THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EC) No 595/2009 of the European Parliament and of the Council of 18 June 2009 on type-approval of motor vehicles and engines with respect to emissions from heavy duty vehicles (Euro VI) and on access to vehicle repair and maintenance information and amending Regulation (EC) No 715/2007 and Directive 2007/46/EC and repealing Directives 80/1269/EEC, 2005/55/EC and 2005/78/EC(1), and in particular Article 4(3) and Article 5(4)(e) thereof,
Having regard to Directive 2007/46/EC of the European Parliament and of the Council of 5 September 2007 establishing a framework for the approval of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles (Framework Directive)(2), and in particular Article 39(7) thereof,
Whereas:
(1) Regulation (EC) No 595/2009 is one of the separate regulatory acts under the type-approval procedure laid down by Directive 2007/46/EC. It empowers the Commission to adopt measures relating to CO2 emissions and fuel consumption of heavy duty vehicles. The present Regulation aims at establishing measures for obtaining accurate information on CO2 emissions and fuel consumption of new heavy-duty vehicles placed on the Union market.
(2) Directive 2007/46/EC sets out the necessary requirements for the purpose of a whole vehicle type-approval.
(3) Commission Regulation (EU) No 582/2011(3) sets out requirements for the approval of heavy-duty vehicles with regard to emissions and access to vehicle repair and maintenance information. Measures for the determination of CO2 emissions and fuel consumption of new heavy-duty vehicles should be part of the type-approval system instituted by this Regulation. A licence to perform simulations to establish CO2 emissions and fuel consumption of a vehicle will be required to obtain the approvals mentioned above.
(4) Emissions from lorries, buses and coaches, which are the most widely representative categories of heavy-duty vehicles, currently represent around 25 % of road transport CO2 emissions and are expected to increase even further in the future. In order to reach the target of a 60 % reduction of CO2 emissions from transport by 2050, effective measures to curb emissions from heavy-duty vehicles need to be introduced.
(5) Until now, no common method has been laid down by Union legislation to measure CO2 emissions and fuel consumption of heavy-duty vehicles, rendering it impossible to objectively compare performance of vehicles or to introduce measures, whether on the Union or national level, that would encourage the introduction of more energy-efficient vehicles. As a consequence, there has been no transparency in the market as regards the energy-efficiency of heavy-duty vehicles.
(6) The heavy-duty vehicle sector is very diversified, with a significant number of different vehicle types and models as well as with a high degree of customisation. The Commission has conducted an in-depth analysis of the available options to measure CO2 emissions and fuel consumption of those vehicles and concluded that in order to obtain unique data for each produced vehicle at the lowest cost, CO2 emissions and fuel consumption of heavy-duty vehicles should be determined using simulation software.
(7) In order to reflect the diversity of the sector, heavy-duty vehicles should be divided into groups of vehicles with a similar axle configuration, chassis configuration and technically permissible maximum laden mass. Those parameters define the purpose of a vehicle and should therefore determine the set of test cycles used for the purpose of the simulation.
(8) Since there is no software available on the market to meet the requirements necessary for the purposes of the assessment of CO2 emissions and fuel consumption of heavy-duty vehicles, the Commission should develop dedicated software to be used for those purposes.
(9) That software should be publically available, open-source, downloadable and executable. It should include a simulation tool for the calculation of CO2 emissions and fuel consumption of specific heavy-duty vehicles. The tool should be conceived to use, as input, the data reflecting the characteristics of the components, separate technical units and systems which have a significant impact on the CO2 emissions and fuel consumption of heavy-duty vehicles – engine, gearbox and additional driveline components, axles, tyres, aerodynamics and auxiliaries. The software should also include pre-processing tools to be used for the verification and pre-processing of the simulation tool input data relating to the engine and vehicle air drag, as well as a hashing tool to be used for the encryption of the simulation tool input and output files.
(10) In order to enable a realistic assessment, the simulation tool should be equipped with a number of functionalities allowing for a simulation of vehicles with different payloads and fuels over specific test cycles assigned to a vehicle depending on its application.
(11) Recognizing the importance of the proper functioning of the software for the correct determination of vehicles' CO2 emissions and fuel consumption and of keeping up with technological progress, the Commission should maintain the software and update it whenever necessary.
(12) The simulations should be performed by vehicle manufacturers before registration, sale or entry into service of a new vehicle in the Union. Provisions should also be put in place for the licence of the vehicle manufacturers' processes for calculation of the CO2 emissions and fuel consumption of vehicles. The processes of handling and application of data by the vehicle manufacturers for the purposes of calculation of the CO2 emissions and fuel consumption of vehicles using the simulation tool should be assessed and closely monitored by the approval authorities in order to ensure that the simulations are conducted in a correct manner. Provisions should therefore be put in place requiring vehicle manufacturers to acquire a licence for the operation of the simulation tool.
(13) The CO2 emissions and fuel consumption related properties of the components, separate technical units and systems having a significant impact on the CO2 emissions and fuel consumption of heavy-duty vehicles should be used as input for the simulation tool.
(14) In order to reflect the specificities of the individual components, separate technical units and systems and to allow for a more precise determination of their CO2 emissions and fuel consumption related properties, provisions for the certification of such properties on the basis of testing should be set out.
(15) For the purpose of limiting the costs of the certification, manufacturers should have the possibility to group into families components, separate technical units and systems with similar design and CO2 emission and fuel consumption characteristics. One component, separate technical unit or system per family with the least favourable characteristics as regards CO2 emissions and fuel consumption within that family should be tested and its results should apply to the entire family.
(16) The costs related to testing may constitute a significant obstacle in particular to companies manufacturing components, separate technical units or systems in small numbers. In order to provide an economically viable alternative to certification, standard values should be set out for certain components, separate technical units and systems with the possibility of using those values instead of the certified values determined on the basis of testing. Standard values should, however, be set out in a way to encourage suppliers of components, separate technical units and systems to apply for certification.
(17) In order to ensure that the results relating to CO2 emissions and fuel consumption declared by the suppliers of components, separate technical units and systems as well as vehicle manufacturers are correct, provisions for verifying and ensuring the conformity of the simulation tool operation as well as of the CO2 emissions and fuel consumption related properties of the relevant components, separate technical units and systems should be set out.
(18) In order to ensure sufficient lead time for the national authorities and the industry, the obligation to determine and declare CO2 emissions and fuel consumption of new vehicles should be implemented gradually for different vehicle groups starting with the vehicles which are the biggest contributors to CO2 emissions of the heavy-duty sector.
(19) The provisions set out in this Regulation form part of the framework established by Directive 2007/46/EC and complement the provisions for type approval with regard to emissions and vehicle repair and maintenance information laid down in Regulation (EU) No 582/2011. To establish a clear relationship between those provisions and this Regulation, Directive 2007/46/EC and Regulation (EU) No 582/2011 should be amended accordingly.
(20) The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee Motor Vehicles,
HAS ADOPTED THIS REGULATION:
This Regulation complements the legal framework for the type-approval of motor vehicles and engines with regard to emissions and vehicle repair and maintenance information established by Regulation (EU) No 582/2011 by laying down the rules for issuing licences to operate a simulation tool with a view to determining CO2 emissions and fuel consumption of new vehicles to be sold, registered or put into service in the Union and for operating that simulation tool and declaring the CO2 emissions and fuel consumption values thus determined.

In case of vehicles equipped with:
a hydraulically driven axles, the axle shall be treated as a non-drivable one and the manufacturer shall not take it into consideration for establishing an axle configuration of a vehicle;
a mechanically driven axles, the axle shall be treated as a drivable one and the manufacturer shall take it into consideration for establishing an axle configuration of a vehicle;
For the highest 50 % of the gears (e.g. for gears 7 to 12 of a 12 gear transmission) the vehicle manufacturer may declare a gear dependent maximum engine torque limit which is not higher than 95 % of the maximum engine torque.
Engine stop-start during vehicle stops: system which automatically shuts down and restarts the internal combustion engine during vehicle stops to reduce engine idling time. For automatic engine shut down the maximum time delay after the vehicle stop shall be not longer than 3 seconds.
Eco-roll without engine stop-start: system which automatically decouples the internal combustion engine from the drivetrain during specific downhill driving conditions with low negative gradients. During these phases the internal combustion engine is operated in engine idling. The system shall be active at least at all cruise control set speeds above 60 km/h.
Eco-roll with engine stop-start: system which automatically decouples the internal combustion engine from the drivetrain during specific downhill driving conditions with low negative slopes. During these phases the internal combustion engine is shut down after a short time delay and keeps shut down during the main share of the eco-roll phase. The system shall be active at least at all cruise control set speeds of above 60 km/h.
Predictive cruise control (PCC): systems which optimise the usage of potential energy during a driving cycle based on an available preview of road gradient data and the use of a GPS system. A PCC system declared in the input to the simulation tool shall have a gradient preview distance longer than 1 000 metres and cover all following functionalities:
Crest coasting
Approaching a crest the vehicle velocity is reduced before the point where the vehicle starts accelerating by gravity alone compared to the set speed of the cruise control so that the braking during the following downhill phase can be reduced.
Acceleration without engine power
During downhill driving with a low vehicle velocity and a high negative slope the vehicle acceleration is performed without any engine power usage so that the downhill braking can be reduced.
Dip coasting
During downhill driving when the vehicle is braking at the overspeed velocity, PCC increases the overspeed for a short period of time to end the downhill event with a higher vehicle velocity. Overspeed is a higher vehicle speed than the set speed of the cruise control system.
A PCC system can be declared as input to the simulation tool if either the functionalities set out in points (1) and (2) or points (1), (2) and (3) are covered.

‘specific mass emissions’ means the total mass emissions divided by the total engine work over a defined period expressed in g/kWh;
‘specific fuel consumption’ means the total fuel consumption divided by the total engine work over a defined period expressed in g/kWh;
‘FCMC’ means fuel consumption mapping cycle;
‘Full load’ means the delivered engine torque/power at a certain engine speed when the engine is operated at maximum operator demand.
The definitions in paragraphs 3.1.5 and 3.1.6. of Annex 4 to UN/ECE Regulation 49 Rev.06 shall not apply.
The calibration laboratory facilities shall comply with the requirements of either ISO/TS 16949, ISO 9000 series or ISO/IEC 17025. All laboratory reference measurement equipment, used for calibration and/or verification, shall be traceable to national or international standards.
Engines shall be grouped into engine CO2-families defined in accordance with Appendix 3. Paragraph 4.1 explains which testruns shall be performed for the purpose of certification of one specific engine CO2-family.
All testruns performed for the purpose of certification of one specific engine CO2-family defined in accordance with Appendix 3 to this Annex shall be conducted on the same physical engine and without any changes to the setup of the engine dynamometer and the engine system, apart from the exceptions defined in paragraph 4.2 and Appendix 3.
The tests shall be conducted under ambient conditions meeting the following conditions over the whole testrun:
The parameter fa describing the laboratory test conditions, determined in accordance with paragraph 6.1 of Annex 4 to UN/ECE Regulation 49 Rev.06, shall be within the following limits: 0,96 ≤ fa ≤ 1,04.
The absolute temperature (Ta) of the engine intake air expressed in Kelvin, determined in accordance with paragraph 6.1 of Annex 4 to UN/ECE Regulation 49 Rev.06 shall be within the following limits: 283 K ≤ Ta ≤ 303 K.
The atmospheric pressure expressed in kPa, determined in accordance with paragraph 6.1 of Annex 4 to UN/ECE Regulation 49 Rev.06 shall be within the following limits: 90 kPa ≤ ps ≤ 102 kPa.
If tests are performed in test cells that are able to simulate barometric conditions other than those existing in the atmosphere at the specific test site, the applicable fa value shall be determined with the simulated values of atmospheric pressure by the conditioning system. The same reference value for the simulated atmospheric pressure shall be used for the intake air and exhaust path and all other relevant engine systems. The actual value of the simulated atmospheric pressure for the intake air and exhaust path and all other relevant engine systems shall be within the limits specified in subpoint (3).
In cases where the ambient pressure in the atmosphere at the specific test site exceeds the upper limit of 102 kPa, tests in accordance with this Annex may still be performed. In this case tests shall be performed with the specific ambient air pressure in the atmosphere.
In cases where the test cell has the ability to control temperature, pressure and/or humidity of engine intake air independent of the atmospheric conditions the same settings for those parameters shall be used for all testruns performed for the purpose of certification of one specific engine CO2-family defined in accordance with Appendix 3 to this Annex.
The test engine shall be installed in accordance with paragraphs 6.3 to 6.6 of Annex 4 to UN/ECE Regulation 49 Rev.06.

In the case of a closed crankcase, the manufacturer shall ensure that the engine's ventilation system does not permit the emission of any crankcase gases into the atmosphere. If the crankcase is of an open type, the emissions shall be measured and added to the tailpipe emissions, following the provisions set out in paragraph 6.10. of Annex 4 to UN/ECE Regulation 49 Rev.06.
During all testruns the charge air cooling system used on the test bed shall be operated under conditions which are representative for in-vehicle application at reference ambient conditions. The reference ambient conditions are defined as 293 K for air temperature and 101,3 kPa for pressure.
The laboratory charge air cooling for tests according to this regulation should comply with the provisions specified in paragraph 6.2 of Annex 4 to UN/ECE Regulation 49 Rev.06.
During all testruns the engine cooling system used on the test bed shall be operated under conditions which are representative for in-vehicle application at reference ambient conditions. The reference ambient conditions are defined as 293 K for air temperature and 101,3 kPa for pressure.
The engine cooling system should be equipped with thermostats according to the manufacturer specification for vehicle installation. If either a non-operational thermostat is installed or no thermostat is used, subpoint (3) shall apply. The setting of the cooling system shall be performed in accordance with subpoint (4).
If no thermostat is used or a non-operational thermostat is installed, the test bed system shall reflect the behavior of the thermostat under all test conditions. The setting of the cooling system shall be performed in accordance with subpoint (4).
[F1The engine coolant flow rate (or alternatively the pressure difference across the engine side of the heat exchanger) and the engine coolant temperature shall be set to a value representative for in-vehicle application at reference ambient conditions when the engine is operated at rated speed and full load with the engine thermostat in fully open position. This setting defines the coolant reference temperature. For all testruns performed for the purpose of certification of one specific engine within one engine CO 2 -family, the cooling system setting shall not be changed, neither on the engine side nor on the test bed side of the cooling system. The temperature of the test bed side cooling medium shall be kept reasonably constant by good engineering judgement. The cooling medium on the test bed side of the heat exchanger shall not exceed the nominal thermostat opening temperatur downstream of the heat exchanger.]
For all testruns performed for the purpose of certification of one specific engine within one engine CO2-family the engine coolant temperature shall be maintained between the nominal value of the thermostat opening temperature declared by the manufacturer and the coolant reference temperature in accordance with subpoint (4) as soon as the engine coolant has reached the declared thermostat opening temperature after engine cold start.
For the WHTC coldstart test performed in accordance with paragraph 4.3.3, the specific initial conditions are specified in paragraphs 7.6.1. and 7.6.2 of Annex 4 to UN/ECE Regulation 49 Rev.06. If simulation of the thermostat behaviour in accordance with subpoint (3) is applied, there shall be no coolant flow across the heat exchanger as long as the engine coolant has not reached the declared nominal thermostat opening temperature after cold start.
The respective reference fuel for the engine systems under test shall be selected from the fuel types listed in Table 1. The fuel properties of the reference fuels listed in Table 1 shall be those specified in Annex IX to Commission Regulation (EU) No 582/2011.
To ensure that the same fuel is used for all testruns performed for the purpose of certification of one specific engine CO2-family no refill of the tank or switch to another tank supplying the engine system shall occur. Exceptionally a refill or switch may be allowed if it can be ensured that the replacement fuel has exactly the same properties as the fuel used before (same production batch).
The NCV for the fuel used shall be determined by two separate measurements in accordance with the respective standards for each fuel type defined in Table 1. The two separate measurements shall be performed by two different labs independent from the manufacturer applying for certification. The lab performing the measurements shall comply with the requirements of ISO/IEC 17025. The approval authority shall ensure that the fuel sample used for determination of the NCV is taken from the batch of fuel used for all testruns.
If the two separate values for the NCV are deviating by more than 440 Joule per gram fuel, the values determined shall be void and the measurement campaign shall be repeated.
[F1The mean value of the two separate NCV that are not deviating by more than 440 Joule per gram fuel shall be documented in MJ/kg rounded to 2 places to the right of the decimal point in accordance with ASTM E 29-06.]
For gas fuels the standards for determining the NCV according to Table 1 contain the calculation of the calorific value based on the fuel composition. The gas fuel composition for determining the NCV shall be taken from the analysis of the reference gas fuel batch used for the certification tests. For the determination of the gas fuel composition used for determining the NCV only one single analysis by a lab independent from the manufacturer applying for certification shall be performed. For gas fuels the NCV shall be determined based on this single analysis instead of a mean value of two separate measurements.
[F2For gas fuels, switches between fuel tanks of different production batches are allowed exceptionally; in that case, the NCV of each used fuel batch should be calculated and the highest value should be documented.]

The engine full load curve shall be recorded in accordance with paragraphs 7.4.1. to 7.4.5. of Annex 4 to UN/ECE Regulation 49 Rev.06.
The recording of the engine motoring curve in accordance with this paragraph shall be omitted for all other engines except the CO2-parent engine of the engine CO2-family defined in accordance with Appendix 3. In accordance with paragraph 6.1.3 the engine motoring curve recorded for the CO2-parent engine of the engine CO2-family shall also be applicable to all engines within the same engine CO2-family.
In the case that upon request of the manufacturer the provisions defined in Article 15(5) of this Regulation are applied, the recording of the engine motoring curve shall be performed additionally for that specific engine.
The engine motoring curve shall be recorded in accordance with option (b) in paragraph 7.4.7. of Annex 4 to UN/ECE Regulation 49 Rev.06. This test shall determine the negative torque required to motor the engine between maximum and minimum mapping speed with minimum operator demand.
The test shall be continued directly after the full load curve mapping according to paragraph 4.3.1. At the request of the manufacturer, the motoring curve may be recorded separately. In this case the engine oil temperature at the end of the full load curve testrun performed in accordance with paragraph 4.3.1 shall be recorded and the manufacturer shall prove to the satisfaction of the an approval authority, that the engine oil temperature at the starting point of the motoring curve meets the aforementioned temperature within ± 2 K.
At the start of the testrun for the engine motoring curve the engine shall be operated with minimum operator demand at maximum mapping speed defined in paragraph 7.4.3. of Annex 4 to UN/ECE Regulation 49 Rev.06. As soon as the motoring torque value has stabilized within ± 5 % of its mean value for at least 10 seconds, the data recording shall start and the engine speed shall be decreased at an average rate of 8 ± 1 min– 1/s from maximum to minimum mapping speed, which are defined in paragraph 7.4.3. of Annex 4 to UN/ECE Regulation 49 Rev.06.
The WHTC test shall be performed in accordance with Annex 4 to UN/ECE Regulation 49 Rev.06. The weighted emission test results shall meet the applicable limits defined in Regulation (EC) No 595/2009.
The engine full load curve recorded in accordance with paragraph 4.3.1 shall be used for the denormalization of the reference cycle and all calculations of reference values performed in accordance with paragraphs 7.4.6, 7.4.7 and 7.4.8 of Annex 4 to UN/ECE Regulation 49 Rev.06.
In addition to the provisions defined in Annex 4 to UN/ECE Regulation 49 Rev.06 the actual fuel mass flow consumed by the engine in accordance with paragraph 3.4 shall be recorded.

In addition to the provisions defined in Annex 4 to UN/ECE Regulation 49 Rev.06 the actual fuel mass flow consumed by the engine in accordance with paragraph 3.4 shall be recorded.
The fuel consumption mapping cycle (FCMC) in accordance with this paragraph shall be omitted for all other engines except the CO2-parent engine of the engine CO2-family. The fuel map data recorded for the CO2-parent engine of the engine CO2-family shall also be applicable to all engines within the same engine CO2-family.
In the case that upon request of the manufacturer the provisions defined in Article 15(5) of this Regulation are applied, the fuel consumption mapping cycle shall be performed additionally for that specific engine.
The engine fuel map shall be measured in a series of steady state engine operation points, as defined according to paragraph 4.3.5.2. The metrics of this map are the fuel consumption in g/h depending on engine speed in min-1 and engine torque in Nm.
If an after-treatment regeneration event occurs during the FCMC for engines equipped with exhaust after-treatment systems that are regenerated on a periodic basis defined in accordance with paragraph 6.6 of Annex 4 to UN/ECE Regulation 49 Rev.06, all measurements at that engine speed mode shall be void. The regeneration event shall be completed and afterwards the procedure shall be continued as described in paragraph 4.3.5.1.1.
If an unexpected interruption, malfunction or error occurs during the FCMC, all measurements at that engine speed mode shall be void and one of the following options how to continue shall be chosen by the manufacturer:
the procedure shall be continued as described in paragraph 4.3.5.1.1
the whole FCMC shall be repeated in accordance with paragraphs 4.3.5.4 and 4.3.5.5
The engine shall be started and warmed up in accordance with paragraph 7.4.1. of Annex 4 to UN/ECE Regulation 49 Rev.06. After warm-up, the engine shall be preconditioned by operating the engine for 20 minutes at mode 9, as defined in Table 1 of paragraph 7.2.2. of Annex 4 to UN/ECE Regulation 49 Rev.06.
The engine full load curve recorded in accordance with paragraph 4.3.1 shall be used for the denormalization of the reference values of mode 9 performed in accordance with paragraphs 7.4.6, 7.4.7 and 7.4.8 of Annex 4 to UN/ECE Regulation 49 Rev.06.
Directly after completion of preconditioning, the target values for engine speed and torque shall be changed linearly within 20 to 46 seconds to the highest target torque setpoint at the next higher target engine speed setpoint than the particular target engine speed setpoint where the interruption of the FCMC occurred. If the target setpoint is reached within less than 46 seconds, the remaining time up to 46 seconds shall be used for stabilization.
For stabilization the engine operation shall continue from that point in accordance with the test sequence specified in paragraph 4.3.5.5 without recording of measurement values.

The grid of target setpoints is fixed in a normalized way and consists of 10 target engine speed setpoints and 11 target torque setpoints. Conversion of the normalized setpoint definition to the actual target values of engine speed and torque setpoints for the individual engine under test shall be based on the engine full load curve of the CO2-parent engine of the engine CO2-family defined in accordance with Appendix 3 to this Annex and recorded in accordance with paragraph 4.3.1.
The 10 target engine speed setpoints are defined by 4 base target engine speed setpoints and 6 additional target engine speed setpoints.
The engine speeds nidle, nlo, npref, n95h and nhi shall be determined from the engine full load curve of the CO2-parent engine of the engine CO2-family defined in accordance with Appendix 3 to this Annex and recorded in accordance with paragraph 4.3.1 by applying the definitions of characteristic engine speeds in accordance with paragraph 7.4.6. of Annex 4 to UN/ECE Regulation 49 Rev.06.

n57 = 0,565 × (0,45 × nlo + 0,45 × npref + 0,1 × nhi – nidle) × 2,0327 + nidle
The 4 base target engine speed setpoints are defined as follows:
Base engine speed 1: nidle
Base engine speed 2: nA = n57 – 0,05 × (n95h – nidle)
Base engine speed 3: nB = n57 + 0,08 × (n95h – nidle)
Base engine speed 4: n95h
The potential distances between the speed setpoints shall be determined by the following equations:

dnB95h_44 = (n95h – nB) / 4
dnidleA_35 = (nA – nidle) / 3
dnB95h_35 = (n95h – nB) / 5
dnidleA_53 = (nA – nidle) / 5
dnB95h_53 = (n95h – nB) / 3
The absolute values of potential deviations between the two sections shall be determined by the following equations:
dn44 = ABS(dnidleA_44 – dnB95h_44)
dn35 = ABS(dnidleA_35 – dnB95h_35)
dn53 = ABS(dnidleA_53 – dnB95h_53)
[F1The 6 additional target engine speed setpoints shall be determined in accordance with the following provisions:
If dn 44 is smaller than or equal to (dn 35 + 5) and also smaller than or equal to (dn 53 + 5), the 6 additional target engine speeds shall be determined by dividing each of the two ranges, one from n idle to n A and the other from n B to n 95h , into 4 equidistant sections.
If (dn 35 + 5) is smaller than dn 44 and also dn 35 is smaller than dn 53 , the 6 additional target engine speeds shall be determined by dividing the range from n idle to n A into 3 equidistant sections and the range from n B to n 95h , into 5 equidistant sections.
If (dn 53 + 5) is smaller than dn 44 and also dn 53 is smaller than dn 35 , the 6 additional target engine speeds shall be determined by dividing the range from n idle to n A into 5 equidistant sections and the range from n B to n 95h , into 3 equidistant sections.]
Figure 1 exemplarily illustrates the definition of the target engine speed setpoints according to subpoint (1) above.
The 11 target torque setpoints are defined by 2 base target torque setpoints and 9 additional target torque setpoints. The 2 base target torque setpoints are defined by zero engine torque and the maximum engine full load of the CO2-parent engine determined in accordance with paragraph 4.3.1. (overall maximum torque Tmax_overall). The 9 additional target torque setpoints are determined by dividing the range from zero torque to overall maximum torque, Tmax_overall, into 10 equidistant sections.
[F1All target torque setpoints at a particular target engine speed setpoint that exceed the limit value defined by the full load torque value at this particular target engine speed setpoint minus 5 percent of T max_overall , shall be replaced by one single target torque setpoint at full load torque at this particular target engine speed setpoint.

The remaining number of engine CO2-families to be tested shall be randomly selected from all existing engine CO2-families and shall be agreed between the manufacturer and the approval authority.
[F1The minimum number of engines to be tested for each engine CO 2 -family, n COP,min , shall be determined by dividing n COP,base by n COP,fam , both values determined in accordance with point 2. The result for n COP,min shall be rounded to the nearest integer. If the resulting value for n COP,min is smaller than 4 it shall be set to 4, if it is greater than 19 it shall be set to 19.]

For diesel engines, the limit values for the assessment of conformity of one single engine tested shall be the target value determined in accordance with point (6) + 4 percent.
For gas engines, the limit values for the assessment of conformity of one single engine tested shall be the target value determined in accordance with point (6) + 5 percent.]
If the cumulative number of nonconforming tests at the nth test determined in accordance with point 9.3 of this Appendix is less than or equal to the pass decision number for the sample size given in Table 4 of Appendix 3 to UN/ECE Regulation 49 Rev.06, a pass decision is reached.

Otherwise, an additional engine is tested in accordance with paragraph 4 of this Appendix and the calculation procedure in accordance with point 9.3 of this Appendix is applied to the sample increased by one more unit.
The engine torque shall be measured at engine motoring with and without fan engaged with the following procedure:
Install the fan according to product instruction before the test starts.
Warm up phase: The engine shall be warmed up according to the recommendation of the manufacturer and by practicing good engineering judgement (eg operating the engine for 20 minutes at mode 9, as defined in Table 1 of paragraph 7.2.2. of Annex 4 to UN/ECE Regulation 49 Rev.06).
[F1Stabilization phase: After the warm-up or optional warm-up step (v) is completed the engine shall be operated with minimum operator demand (motoring) at engine speed n pref for 130 ± 2 seconds with the fan disengaged (n fan_disengage < 0,75 * n engine * r fan ). The first 60 ± 1 seconds of this period are considered as a stabilization period, during which the actual engine speed shall be held within ± 5 min – 1 of n pref .]
Measurement phase: During the following period of 60 ± 1 seconds the actual engine speed shall be held within ± 2 min– 1 of npref and the coolant temperature within ± 5 °C while the torque for motoring the engine with the fan disengaged, the fan speed and the engine speed shall be recorded as an average value over this period of 60 ± 1 seconds. The remaining period of 10 ± 1 seconds shall be used for data post-processing and storage if necessary.
Optional warmup phase: Upon manufacturer's request and according to good engineering judgement step (ii) can be repeated (e.g. if the temperature has dropped more than 5 °C)
Stabilization phase: After the optional warm-up is completed the engine shall be operated with minimum operator demand (motoring) at engine speed npref for 130 ± 2 seconds with the fan engaged (nfan_engage > 0,9 * nengine * rfan) The first 60 ± 1 seconds of this period are considered as a stabilization period, during which the actual engine speed shall be held within ± 5 min– 1 of npref.
Measurement phase: During the following period of 60 ± 1 seconds the actual engine speed shall be held within ± 2 min– 1 of npref and the coolant temperature within ± 5 °C while the torque for motoring the engine with the fan engaged, the fan speed and the engine speed shall be recorded as an average value over this period of 60 ± 1 seconds. The remaining period of 10±1 seconds shall be used for data post-processing and storage if necessary.
Steps (iii) to (vii) shall be repeated at engine speeds n95h and nhi instead of npref, with an optional warmup step (v) before each stabilization step if needed to maintain a stable coolant temperature (± 5 °C), according to good engineering judgement.
If the standard deviation of all calculated Ci according to the equation below at the three speeds npref, n95h and nhi is equal or higher than 3 percent, the measurement shall be performed for all engine speeds defining the grid for the fuel mapping procedure (FCMC) according to paragraph 4.3.5.2.1.
The actual fan constant shall be calculated from the measurement data according to the following equation:
where:
fan constant at certain engine speed

measured engine torque at motoring with fan engaged (Nm)
fan speed with fan engaged (min– 1)
fan speed with fan disengaged min– 1)
ratio of the speed of the engine-side of the fan clutch to the speed of the crankshaft]
If the standard deviation of all calculated Ci at the three speeds npref, n95h and nhi is less than 3 %, an average value Cavg-fan determined over the three speeds npref, n95h and nhi shall be used for the fan constant.
If the standard deviation of all calculated Ci at the three speeds npref, n95h and nhi is equal or higher than 3 %, individual values determined for all engine speeds according to point (ix) shall be used for the fan constant Cind-fan,i. The value of the fan constant for the actual engine speed Cfan, shall be determined by linear interpolation between the individual values Cind-fan,i of the fan constant.
The engine torque for driving the fan shall be calculated according to the following equation:
Mfan = Cfan · nfan 2 · 10– 6
where:
engine torque for driving fan (Nm)
fan constant Cavg-fan or Cind-fan,i corresponding to nengine
The mechanical power consumed by the fan shall be calculated from the engine torque for driving the fan and the actual engine speed. Mechanical power and engine torque shall be taken into account in accordance with paragraph 3.1.2.
The electric power supplied externally to electric engine components shall be measured. This measured value shall be corrected to mechanical power by dividing it by a generic efficiency value of 0,65. This mechanical power and the corresponding engine torque shall be taken into account in accordance with paragraph 3.1.2.

This Appendix describes the most important evaluation steps and underlying basic equations that are performed by the engine pre-processing tool. The following steps are performed during evaluation of the input data in the order listed:
This annex describes the certification provisions regarding the torque losses of transmissions, torque converter (TC), other torque transferring components (OTTC) and additional driveline components (ADC) for heavy duty vehicles. In addition it defines calculation procedures for the standard torque losses.
Torque converter (TC), other torque transferring components (OTTC) and additional driveline components (ADC) can be tested in combination with a transmission or as a separate unit. In the case that those components are tested separately the provisions of section 4, 5 and 6 apply. Torque losses resulting from the drive mechanism between the transmission and those components can be neglected.
For the purposes of this Annex the following definitions shall apply:
‘Transfer case’ means a device that splits the engine power of a vehicle and directs it to the front and rear drive axles. It is mounted behind the transmission and both front and rear drive shafts connect to it. It comprises either a gearwheel set or a chain drive system in which the power is distributed from the transmission to the axles. The transfer case will typically have the ability to shift between standard drive mode (front or rear wheel drive), high range traction mode (front and rear wheel drive), low range traction mode and neutral;
‘Gear ratio’ means the forward gear ratio of the speed of the input shaft (towards prime mover) to the speed of the output shaft (towards driven wheels) without slip (i = nin/nout );
‘Ratio coverage’ means the ratio of the largest to the smallest forward gear ratios in a transmission: φtot = imax/imin ;
‘Compound transmission’ means a transmission, with a large number of forward gears and/or large ratio coverage, composed of sub-transmissions, which are combined to use most power-transferring parts in several forward gears;
‘Main section’ means the sub-transmission that has the largest number of forward gears in a compound transmission;
‘Range section’ means a sub-transmission normally in series connection with the main section in a compound transmission. A range section usually has two shiftable forward gears. The lower forward gears of the complete transmission are embodied using the low range gear. The higher gears are embodied using the high range gear;
‘Splitter’ means a design that splits the main section gears in two (usually) variants, low- and high split gears, whose gear ratios are close compared to the ratio coverage of the transmission. A splitter can be a separate sub-transmission, an add-on device, integrated with the main section or a combination thereof;
‘Tooth clutch’ means a clutch where torque is transferred mainly by normal forces between mating teeth. A tooth clutch can either be engaged or disengaged. It is operated in load-free conditions, only (e.g., at gear shifts in a manual transmission);
‘Angle drive’ means a device that transmits rotational power between non-parallel shafts, often used with transversely oriented engine and longitudinal input to driven axle;
‘Friction clutch’ means clutch for transfer of propulsive torque, where torque is sustainably transferred by friction forces. A friction clutch can transmit torque while slipping, it can thereby (but does not have to) be operated at start-offs and at powershifts (retained power transfer during a gear shift);
‘Synchroniser’ means a type of tooth clutch where a friction device is used to equalise the speeds of the rotating parts to be engaged;
‘Gear mesh efficiency’ means the ratio of output power to input power when transmitted in a forward gear mesh with relative motion;
‘Crawler gear’ means a low forward gear (with speed reduction ratio that is larger than for the non-crawler gears) that is designed to be used infrequently, e.g., at low-speed manoeuvres or occasional up-hill start-offs;
‘Power take-off (PTO)’ means a device on a transmission or an engine to which an auxiliary driven device, e.g., a hydraulic pump, can be connected;
‘Power take-off drive mechanism’ means a device in a transmission that allows the installation of a power take-off (PTO);
‘Lock-up clutch’ means a friction clutch in a hydrodynamic torque converter; it can connect the input and output sides, thereby eliminating the slip;
‘Start-off clutch’ means a clutch that adapts speed between engine and driven wheels when the vehicle starts off. The start-off clutch is usually located between engine and transmission;
‘Synchronised Manual Transmission (SMT)’ means a manually operated transmission with two or more selectable speed ratios that are obtained using synchronisers. Ratio changing is normally achieved during a temporary disconnection of the transmission from the engine using a clutch (usually the vehicle start-off clutch);
‘Automated Manual Transmission or Automatic Mechanically-engaged Transmission (AMT)’ means an automatically shifting transmission with two or more selectable speed ratios that are obtained using tooth clutches (un-/synchronised). Ratio changing is achieved during a temporary disconnection of the transmission from the engine. The ratio shifts are performed by an electronically controlled system managing the timing of the shift, the operation of the clutch between engine and gearbox and the speed and torque of the engine. The system selects and engages the most suitable forward gear automatically, but can be overridden by the driver using a manual mode;
‘Dual Clutch Transmission (DCT)’ means an automatically shifting transmission with two friction clutches and several selectable speed ratios that are obtained by the use of tooth clutches. The ratio shifts are performed by an electronically controlled system managing the timing of the shift, the operation of the clutches and the speed and torque of the engine. The system selects the most suitable gear automatically, but can be overridden by the driver using a manual mode;
‘Retarder’ means an auxiliary braking device in a vehicle powertrain; aimed for permanent braking;
‘Case S’ means the serial arrangement of a torque converter and the connected mechanical parts of the transmission;
‘Case P’ means the parallel arrangement of a torque converter and the connected mechanical parts of the transmission (e.g. in power split installations);
‘Automatic Powershifting Transmission (APT)’ means an automatically shifting transmission with more than two friction clutches and several selectable speed ratios that are obtained mainly by the use of those friction clutches. The ratio shifts are performed by an electronically controlled system managing the timing of the shift, the operation of the clutches and the speed and torque of the engine. The system selects the most suitable gear automatically, but can be overridden by the driver using a manual mode. Shifts are normally performed without traction interruption (friction clutch to friction clutch);
‘Oil conditioning system’ means an external system that conditions the oil of a transmission at testing. The system circulates oil to and from the transmission. The oil is thereby filtered and/or temperature conditioned;
‘Smart lubrication system’ means a system that will affect the load independent losses (also called spin losses or drag losses) of the transmission depending on the input torque and/or power flow through the transmission. Examples are controlled hydraulic pressure pumps for brakes and clutches in an APT, controlled variable oil level in the transmission, controlled variable oil flow/pressure for lubrication and cooling in the transmission. Smart lubrication can also include control of the oil temperature of the transmission, but smart lubrication systems that are designed only for controlling the temperature are not considered here, since the transmission testing procedure has fixed testing temperatures;
‘Transmission electric auxiliary’ means an electric auxiliary used for the function of the transmission during running steady state operation. A typical example is an electric cooling/lubrication pump (but not electric gear shift actuators and electronic control systems including electric solenoid valves, since they are low energy consumers, especially at steady state operation);
‘Oil type viscosity grade’ means a viscosity grade as defined by SAE J306;
‘Factory fill oil’ means the oil type viscosity grade that is used for the oil fill in the factory and which is intended to stay in the transmission, torque converter, other torque transferring component or in an additional driveline component for the first service interval;
‘Gearscheme’ means the arrangement of shafts, gearwheels and clutches in a transmission;
‘Powerflow’ means the transfer path of power from input to output in a transmission via shafts, gearwheels and clutches.
For testing the losses of a transmission the torque loss map for each individual transmission type shall be measured. Transmissions may be grouped into families with similar or equal CO2-relevant data following the provisions of Appendix 6 to this Annex.
For the determination of the transmission torque losses, the applicant for a certificate shall apply one of the following methods for each single forward gear (crawler gears excluded).
Option 1: Measurement of the torque independent losses, calculation of the torque dependent losses.
Option 2: Measurement of the torque independent losses, measurement of the torque loss at maximum torque and interpolation of the torque dependent losses based on a linear model
Option 3: Measurement of the total torque loss.
The torque loss Tl ,in on the input shaft of the transmission shall be calculated by
Tl,in (nin , Tin , gear) = T l,in,min_loss + fT * Tin + floss_corr * Tin + T l,in,min_el + fel_corr * Tin
The correction factor for the torque dependent hydraulic torque losses shall be calculated by
The correction factor for the torque dependent electric torque losses shall be calculated by
The torque loss at the input shaft of the transmission caused by the power consumption of transmission electric auxiliary shall be calculated by

For each gear a torque loss map covering the defined input speed and input torque steps shall be determined with one of the specified testing options or standard torque loss values. For the input file for the simulation tool, this basic torque loss map shall be complemented as described in the following:
Calculated fallback values (Appendix 8)
Option 1
Option 2 or 3 in combination with a torque sensor for higher output torques (if required)
For cases (i) and (ii) in Option 2, the torque losses at load shall be measured at the input torque that corresponds to output torque 10 kNm and/or the specified maximum input power.
The torque converter characteristics to be determined for the simulation tool input consist of Tpum 1000 (the reference torque at 1 000 rpm input speed) and μ (the torque ratio of the torque converter). Both are depending on the speed ratio v (= output (turbine) speed / input (pump) speed for the torque converter) of the torque converter.
For determination of the characteristics of the TC, the applicant for a certificate shall apply the following method, irrespective of the chosen option for the assessment of the transmission torque losses.
To take the two possible arrangements of the TC and the mechanical transmission parts into account, the following differentiation between case S and P shall apply:
:
TC and mechanical transmission parts in serial arrangement
:
TC and mechanical transmission parts in parallel arrangement (power split installation)
For case S arrangements the TC characteristics may be evaluated either separate from the mechanical transmission or in combination with the mechanical transmission. For case P arrangements the evaluation of TC characteristic is only possible in combination with the mechanical transmission. However, in this case and for the hydromechanical gears subject to measurement the whole arrangement, torque converter and mechanical transmission, is considered as a TC with similar characteristic curves as a sole torque converter.
For the determination of the torque converter characteristics two measurement options may be applied:
Option A: measurement at constant input speed
Option B: measurement at constant input torque according to SAE J643
The manufacturer may choose option A or B for case S and case P arrangements.
For the input to the simulation tool, the torque ratio μ and reference torque Tpum of the torque converter shall be measured for a range of v ≤ 0,95 (= vehicle propulsion mode). The range of v ≥ 1,00 (= vehicle coasting mode) may either be measured or covered by using the standard values of Table 1.
In case of measurements together with a mechanical transmission the overrun point may be different from v = 1,00 and therefor the range of measured speed ratios shall be adjusted accordingly.
In case of use of standard values the data on torque converter characteristics provided to the simulation tool shall only cover the range of v ≤ 0,95 (or the adjusted speed ratio). The simulation tool automatically adds the standard values for overrun conditions.

The scope of this section includes engine retarders, transmission retarders, driveline retarders, and components that are treated in the simulation tool as a retarder. These components include vehicle starting devices like a single wet transmission input clutch or hydro-dynamic clutch.
The retarder drag torque loss is a function of the retarder rotor speed. Since the retarder can be integrated in different parts of the vehicle driveline, the retarder rotor speed depends on the drive part (= speed reference) and step-up ratio between drive part and retarder rotor as shown in Table 2.
Retarder rotor speeds
where:
=
step-up ratio = retarder rotor speed/drive part speed
=
transmission ratio = transmission input speed/transmission output speed
Retarder configurations that are integrated in the engine and cannot be separated from the engine shall be tested in combination with the engine. This section does not cover these non-separable engine integrated retarders.
Retarders that can be disconnected from the driveline or the engine by any kind of clutch are considered to have zero rotor speed in disconnected condition and therefore have no power losses.
The retarder drag losses shall be measured with one of the following two methods:
Measurement on the retarder as a stand-alone unit
Measurement in combination with the transmission
In case the losses are measured on the retarder as stand-alone unit, the results are affected by the torque losses in the bearings of the test setup. It is permitted to measure these bearing losses and subtract them from the retarder drag loss measurements.
The manufacturer shall guarantee that the retarder used for the measurements is in accordance with the drawing specifications for series production retarders.
Modifications to the retarder to meet the testing requirements of this Annex, e.g. for the inclusion of measurement sensors or the adaption of an external oil conditioning systems are permitted.
Based on the family described in Appendix 6 to this Annex, measured drag losses for transmissions with retarder can be used for the same (equivalent) transmission without retarder.
The use of the same transmission unit for measuring the torque losses of variants with and without retarder is permitted.
Upon request of the approval authority the applicant for a certificate shall specify and prove the conformity with the requirements defined in this Annex.
On request of the applicant a run-in procedure may be applied to the retarder. The following provisions shall apply for a run-in procedure.
The ambient temperature during the test shall be in a range of 25 °C ± 10 K.
The ambient temperature shall be measured 1 m laterally from the retarder.
For magnetic retarders the minimum ambient pressure shall be 899 hPa according to International Standard Atmosphere (ISA) ISO 2533.
For hydrodynamic retarders:
Except for the fluid, no external heating is allowed.
In case of testing as stand-alone unit, the retarder fluid temperature (oil or water) shall not exceed 87 °C.
In case of testing in combination with transmission, the oil temperature limits for transmission testing shall apply.
New, recommended first fill oil for the European market shall be used in the test.
For water retarders the water quality shall meet the specifications set out by the manufacturer for the retarder. The water pressure shall be set to a fixed value close to vehicle condition (1 ± 0,2 bar relative pressure at retarder input hose).
If several oils are recommended for first fill, they are considered to be equal if the oils have a kinematic viscosity within 50 % of each other at the same temperature (within the specified tolerance band for KV100).
The oil/water level shall meet the nominal specifications for the retarder.
The electric machine, the torque sensor, and speed sensor shall be mounted at the input side of the retarder or transmission.
The installation of the retarder (and transmission) shall be done with an inclination angle as for installation in the vehicle according to the homologation drawing ± 1° or at 0° ± 1°.
As specified for transmission testing in 3.1.4.
As specified for transmission testing in 3.1.6.1.
The torque loss measurement sequence for the retarder testing shall follow the provisions for the transmission testing defined in 3.1.6.3.2. to 3.1.6.3.5.
When the retarder is tested as stand-alone unit, torque loss measurements shall be conducted using the following speed points:
200, 400, 600, 900, 1 200, 1 600, 2 000, 2 500, 3 000, 3 500, 4 000, 4 500, 5 000, continued up to the maximum retarder rotor speed.
[F1The load-independent torque loss for the complete transmission including retarder shall be measured as defined in point 3.1. for transmission testing in one of the higher transmission gears:
= T l,in,withret]
The retarder and related parts shall be replaced with parts required for the equivalent transmission variant without retarder. The measurement of point (1) shall be repeated.
= Tl,in,withoutret
The load-independent torque loss for the retarder system shall be determined by calculating the differences between the two test data sets
= Tl,in,retsys = Tl,in,withret – Tl,in,withoutret
As specified for transmission testing in 3.1.5.
All recorded data shall be checked and processed as defined for transmission testing in 3.1.7.

:
Measured torque independent losses and calculated torque dependent losses (Transmission test option 1)

In case the angle drive is tested in combination with a transmission, the testing shall follow one of the defined options for transmission testing:
:
Measured torque independent losses and calculated torque dependent losses (Transmission test option 1)
:
Measured torque independent losses and measured torque dependent losses at full load (Transmission test option 2)
:
Measurement under full load points (Transmission test option 3)
The torque loss for the complete transmission including angle drive shall be measured as defined for the applicable transmission testing option

The angle drive and related parts shall be replaced with parts required for the equivalent transmission variant without angle drive. The measurement of point (1) shall be repeated.

This Annex describes the certification provisions regarding the torque losses of propulsion axles for heavy duty vehicles. Alternatively to the certification of axles the calculation procedure for the standard torque loss as defined in Appendix 3 to this Annex can be applied for the purpose of the determination of vehicle specific CO2 emissions.
For the purposes of this Annex the following definitions shall apply:
‘Single reduction axle (SR)’ means a driven axle with only one gear reduction, typically a bevel gear set with or without hypoid offset.
‘Single portal axle (SP)’ means an axle, that has typically a vertical offset between the rotating axis of the crown gear and the rotating axis of the wheel due to the demand of a higher ground clearance or a lowered floor to allow a low floor concept for inner city buses. Typically, the first reduction is a bevel gear set, the second one a spur gear set with vertical offset close to the wheels.
‘Hub reduction axle (HR)’ means a driven axle with two gear reductions. The first is typically a bevel gear set with or without hypoid offset. The other is a planetary gear set, what is typically placed in the area of the wheel hubs.
‘Single reduction tandem axle (SRT)’ means a driven axle that is basically similar to a single driven axle, but has also the purpose to transfer torque from the input flange over an output flange to a further axle. The torque can be transferred with a spur gear set close at the input flange to generate a vertical offset for the output flange. Another possibility is to use a second pinion at the bevel gear set, what takes off torque at the crown wheel.
‘Hub reduction tandem axle (HRT)’ means a hub reduction axle, what has the possibility to transfer torque to the rear as described under single reduction tandem axle (SRT).
‘Axle housing’ means the housing parts that are needed for structural capability as well as for carrying the driveline parts, bearings and sealings of the axle.
‘Pinion’ means a part of a bevel gear set which usually consists of two gears. The pinion is the driving gear which is connected with the input flange. In case of a SRT / HRT, a second pinion can be installed to take off torque from the crown wheel.
‘Crown wheel’ means a part of a bevel gear set which usually consists of two gears. The crown wheel is the driven gear and is connected with the differential cage.
‘Hub reduction’ means the planetary gear set that is installed commonly outside the planetary bearing at hub reduction axles. The gear set consists of three different gears. The sun, the planetary gears and the ring gear. The sun is in the centre, the planetary gears are rotating around the sun and are mounted to the planetary carrier that is fixed to the hub. Typically, the number of planetary gears is between three and five. The ring gear is not rotating and fixed to the axle beam.
‘Planetary gear wheels’ means the gears that rotate around the sun within the ring gear of a planetary gear set. They are assembled with bearings on a planetary carrier, what is joined to a hub.
‘Oil type viscosity grade’ means a viscosity grade as defined by SAE J306.
‘Factory fill oil’ means the oil type viscosity grade that is used for the oil fill in the factory and which is intended to stay in the axle for the first service interval.
‘Axle line’ means a group of axles that share the same basic axle-function as defined in the family concept.
‘Axle family’ means a manufacturer's grouping of axles which through their design, as defined in Appendix 4 of this Annex, have similar design characteristics and CO2 and fuel consumption properties.
‘Drag torque’ means the required torque to overcome the inner friction of an axle when the wheel ends are rotating freely with 0 Nm output torque.
‘Mirror inverted axle casing’ means the axle casing is mirrored regarding to the vertical plane.
‘Axle input’ means the side of the axle on which the torque is delivered to the axle.
‘Axle output’ means the side(s) of the axle where the torque is delivered to the wheels.
The axle gears and all bearings, except wheel end bearings used for the measurements, shall not be used.
On request of the applicant different gear ratios can be tested in one axle housing using the same wheel ends.
Different axle ratios of hub reduction axles and single portal axles (HR, HRT, SP) may be measured by exchanging the hub reduction only. The provisions as specified in Appendix 4 to this Annex shall apply.
The total run-time for the optional run-in and the measurement of an individual axle (except for the axle housing and wheel-ends) shall not exceed 120 hours.
For testing the losses of an axle the torque loss map for each ratio of an individual axle shall be measured, however axles can be grouped in axle families following the provisions of Appendix 4 to this Annex.
On request of the applicant a run-in procedure may be applied to the axle. The following provisions shall apply for a run-in procedure.
The temperature in the test cell shall be maintained to 25 °C ± 10 °C. The ambient temperature shall be measured within a distance of 1 m to the axle housing. Forced heating of the axle may only be applied by an external oil conditioning system as described in 4.1.5.
The oil temperature shall be measured at the centre of the oil sump or at any other suitable point in accordance with good engineering practice. In case of external oil conditioning, alternatively the oil temperature can be measured in the outlet line from the axle housing to the conditioning system within 5 cm downstream the outlet. In both cases the oil temperature shall not exceed 70 °C.
Only recommended factory fill oils as specified by the axle manufacturer shall be used for the measurement. In the case of testing different gear ratio variants with one axle housing, new oil shall be filled in for each single measurement.
If different oils with multiple viscosity grades are specified for the factory fill, the manufacturer shall choose the oil with the highest viscosity grade for performing the measurements on the parent axle.
If more than one oil within the same viscosity grade is specified within one axle family as factory fill oil, the applicant may choose one oil of these for the measurement related to certification.
The oil level or filling volume shall be set to the maximum level as defined in the manufacturer's maintenance specifications.
An external oil conditioning and filtering system is permitted. The axle housing may be modified for the inclusion of the oil conditioning system.
The oil conditioning system shall not be installed in a way which would enable changing oil levels of the axle in order to raise efficiency or to generate propulsion torques in accordance with good engineering practice.
For the purpose of the torque loss measurement different test set-ups are permitted as described in paragraph 4.2.3 and 4.2.4.
In case of a tandem axle, each axle shall be measured separately. The first axle with longitudinal differential shall be locked. The output shaft of drive-through axles shall be installed freely rotatable.
A test set-up considered ‘Type A’ consists of a dynamometer on the axle input side and at least one dynamometer on the axle output side(s). Torque measuring devices shall be installed on the axle input- and output- side(s). For type A set-ups with only one dynamometer on the output side, the free rotating end of the axle shall be locked.
To avoid parasitic losses, the torque measuring devices shall be positioned as close as possible to the axle input- and output- side(s) being supported by appropriate bearings.
Additionally mechanical isolation of the torque sensors from parasitic loads of the shafts, for example by installation of additional bearings and a flexible coupling or lightweight cardan shaft between the sensors and one of these bearings can be applied. Figure 1 shows an example for a test test-up of Type A in a two dynamometer lay-out.
For Type A test set-up configurations the manufacturer shall provide an analysis of the parasitic loads. Based on this analysis the approval authority shall decide about the maximum influence of parasitic loads. However the value ipara cannot be lower than 10 %.
Any other test set-up configuration is called test set-up Type B. The maximum influence of parasitic loads ipara for those configurations shall be set to 100 %.
Lower values for ipara may be used in agreement with the approval authority.
To determine the torque loss map for an axle, the basic torque loss map data shall be measured and calculated as specified in paragraph 4.4. [F1The torque loss results shall be complemented in accordance with 4.4.8 and formatted in accordance with Appendix 6 for the further processing by the simulation tool.]
The calibration laboratory facilities shall comply with the requirements of either ISO/TS 16949, ISO 9000 series or ISO/IEC 17025. All laboratory reference measurement equipment, used for calibration and/or verification, shall be traceable to national (international) standards.
The torque measurement uncertainty shall be calculated and included as described in paragraph 4.4.7.
The sample rate of the torque sensors shall be in accordance with 4.3.2.1.
The uncertainty of the rotational speed sensors for the measurement of input and output speed shall not exceed ± 2 rpm.
The uncertainty of the temperature sensors for the measurement of the ambient temperature shall not exceed ± 1 °C.
The uncertainty of the temperature sensors for the measurement of the oil temperature shall not exceed ± 0,5 °C.
The following signals shall be recorded for the purpose of the calculation of the torque losses:
Input and output torques [Nm]
Input and/or output rotational speeds [rpm]
Ambient temperature [°C]
Oil temperature [°C]
Temperature at the torque sensor
Torque: 1 kHz
Rotational speed: 200 Hz
Temperatures: 10 Hz
Signal filtering may be applied in agreement with the approval authority. Any aliasing effect shall be avoided.
The extent of the torque loss map to be measured is limited to:
either an output torque of 10 kNm
or an input torque of 5 kNm
or the maximum engine power tolerated by the manufacturer for a specific axle or in case of multiple driven axles according to the nominal power distribution.
If the radius of the smallest tire is reduced (e.g. product development) after completing the measurement of an axle or when the physic boundaries of the test stand are reached (e.g. by product development changes), the missing points may be extrapolated by the manufacturer out of the existing map. The extrapolated points shall not exceed more than 10 % of all points in the map and the penalty for these points is 5 % torque loss to be added on the extrapolated points.
:
250 Nm steps
:
500 Nm steps
:
1 000 Nm steps
:
2 000 Nm steps
If the maximum input torque is limited by the manufacturer, the last torque step to be measured is the one below this maximum without consideration of any losses. In that case an extrapolation of the torque loss shall be applied up to the torque corresponding to the manufacturer's limitation with the linear regression based on the torque steps of the corresponding speed step.
The range of test speeds shall comprise from 50 rpm wheel speed to the maximum speed. The maximum test speed to be measured is defined by either the maximum axle input speed or the maximum wheel speed, whichever of the following conditions is reached first:
The maximum applicable axle input speed may be limited to design specification of the axle.
The maximum wheel speed is measured under consideration of the smallest applicable tire diameter at a vehicle speed of 90 km/h for trucks and 110 km/h for coaches. If the smallest applicable tire diameter is not defined, paragraph 4.3.4.1 shall apply.
The wheel speed step width for testing shall be 50 rpm.
For each speed step the torque loss shall be measured for each output torque step starting from 250 Nm upward to the maximum and downward to the minimum. The speed steps can be run in any order. [F2The torque measurement sequence shall be performed and recorded twice.]
Interruptions of the sequence for cooling or heating purposes are permitted.
[F1The measurement duration for each single grid point shall be 5-20 seconds.]
[F1The recorded values for each grid point within the 5-20 seconds interval in accordance with point 4.4.2 shall be averaged to an arithmetic mean.]
All four averaged intervals of corresponding speed and torque grid points from both sequences measured each upward and downward shall be averaged to an arithmetic mean and result into one torque loss value.

If the limits of UT,in are exceeded:
Tloss,rep = Tloss + ΔUTin

An axle family is characterized by design and performance parameters. These shall be common to all axles within the family. The axle manufacturer may decide which axle belongs to an axle family, as long as the family criteria of paragraph 4 are respected. In addition to the parameters listed in paragraph 4, the axle manufacturer may introduce additional criteria allowing the definition of families of more restricted size. These parameters are not necessarily parameters that have an influence on the level of performance. The axle family shall be approved by the approval authority. The manufacturer shall provide to the approval authority the appropriate information relating to the performance of the members of the axle family.
In some cases there may be interaction between parameters. This shall be taken into consideration to ensure that only axles with similar characteristics are included within the same axle family. These cases shall be identified by the manufacturer and notified to the approval authority. It shall then be taken into account as a criterion for creating a new axle family.
In case of parameters, which are not listed in paragraph 3 and which have a strong influence on the level of performance, this parameters shall be identified by the manufacturer on the basis of good engineering practice, and shall be notified to the approval authority.

An air drag family is characterized by design and performance parameters. These shall be common to all vehicles within the family. The manufacturer may decide which vehicles belong to an air drag family as long as the membership criteria listed in paragraph 4 are respected. The air drag family shall be approved by the approval authority. The manufacturer shall provide to the approval authority the appropriate information relating to the air drag of the members of the air drag family.
In some cases there may be interaction between parameters. This shall be taken into consideration to ensure that only vehicles with similar characteristics are included within the same air drag family. These cases shall be identified by the manufacturer and notified to the approval authority. It shall then be taken into account as a criterion for creating a new air drag family.
In addition to the parameters listed in paragraph 4, the manufacturer may introduce additional criteria allowing the definition of families of more restricted size.
Same cabin width and body in white geometry up to B-pillar and above the heel point excluding the cab bottom (e.g. engine tunnel). All members of the family stay within a range of ± 10 mm to the parent vehicle.
Same roof height in vertical Z. All members of the family stay within a range of ± 10 mm to the parent vehicle.
Same height of cabin over frame. This criterion is fulfilled if the height difference of the cabins over frame stays within Z < 175mm.
The fulfillment of the family concept requirements shall be demonstrated by CAD (computer-aided design) data.

12 | Vehicle group 10 | Transfer of already transferred values allowed |
[F116 | Vehicle group 9 + 0,3 m 2 | Applicable vehicle group for transfer has to match with gross vehicle weight. Transfer to already transferred values allowed.] |
The ambient temperature of the constant speed test shall be within a range of ± 5 °C to the value from the certification measurement. This criterion is verified based on the average temperature from the first low speed tests as calculated by the air drag pre-processing tool.
The high speed test shall be performed in a vehicle speed range within ± 2 km/h to the value from the certification measurement.
All conformity of the certified CO2 emissions and fuel consumption related properties tests shall be supervised by the approval authority.
[F2For calculation of C d A cr (0) value the air drag pre-processing tool version of the parent air drag in accordance with Attachment 1 of Appendix 2 to this Annex shall be used.]

This Annex sets out the requirements for the verification testing procedure which is the test procedure for verifying the CO 2 emissions of new heavy-duty vehicles.
The verification testing procedure consists of an on-road test to verify the CO 2 emissions of new vehicles after production. It shall be carried out by the vehicle manufacturer and verified by the approval authority that granted the licence to operate the simulation tool.
During the verification testing procedure the torque and speed at the driven wheels, the engine speed, the fuel consumption, the engaged gear of the vehicle and the other relevant parameters listed in point 6.1.6 shall be measured. The measured data shall be used as input to the simulation tool, which uses the vehicle-related input data and the input information from the determination of the CO 2 emissions and fuel consumption of the vehicle. For the verification testing procedure simulation, the instantaneously measured wheel torque and the rotational speed of the wheels as well as the engine speed shall be used as input, as described in Figure 1 instead of the vehicle speed, in accordance with point 6.1.6. The fan power during the verification testing procedure shall be calculated in accordance with the measured fan speed. The measured fuel consumption shall be within the tolerances set out in point 7 and compared to the fuel consumption simulated with the verification data set to pass the verification testing procedure.
As part of the verification testing procedure, the correctness of the vehicle input data set from the certification of CO 2 emissions and fuel consumption related properties of the components, separate technical units and systems shall also be reviewed to check the data and the data handling process. The correctness of the input data relating to components, separate technical units and systems relevant for air drag and for rolling resistance of the vehicle shall be verified in accordance with point 6.1.1.
For the purposes of this Annex the following definitions shall apply:
‘verification test relevant data set’ means a set of input data for components, separate technical units and systems and input information used for CO 2 determination of a verification testing procedure relevant vehicle;
‘verification testing procedure relevant vehicle’ means a new vehicle for which a value of CO 2 emissions and fuel consumption was determined and declared in accordance with Article 9;
‘ corrected actual mass of the vehicle ’ means the corrected actual mass of the vehicle in accordance with point 2(4) of Annex III;
‘ actual mass of the vehicle ’ is as defined in Article 2(6) of Regulation (EU) No 1230/2012;
‘ actual mass of the vehicle with payload ’ means the actual mass of the vehicle with the superstructure and with the payload applied in the verification testing procedure;
‘ wheel power ’ means the total power at the driven wheels of a vehicle to overcome all driving resistances at the wheel, computed in the simulation tool from the measured torque and rotational speed of the driven wheels;
‘ control area network signal ’ or ‘ CAN signal ’ means a signal from the connection with the vehicle electronic control unit as referred to in paragraph 2.1.5 of Appendix 1 to Annex II to Regulation (EU) No 582/2011;
‘ urban driving ’ means the total distance driven during the fuel consumption measurement at speeds below 50 km/h;
‘ rural driving ’ means the total distance driven during the fuel consumption measurement at speeds from 50 km/h to 70 km/h;
‘ motorway driving ’ means the total distance driven in the fuel consumption measurement at speeds above 70 km/h;
‘crosstalk’ means the signal at the main output of a sensor (M y ), produced by a measurand (F z ) acting on the sensor, which is different from the measurand assigned to this output; the coordinate system assignment is defined in accordance with ISO 4130.
The number of new vehicles to be tested per year of production ensures that the relevant variations of components, separate technical units or systems used are covered by the verification testing procedure. The vehicle selection for the verification test shall be based on following requirements:
The vehicles for verification test shall be selected out of the vehicles from the production line for which a value of CO 2 emissions and fuel consumption has been determined and declared in accordance with Article 9. The components, separate technical units or systems mounted in or on the vehicle shall be out of series production and shall correspond to those mounted at production date of the vehicle.
The vehicle selection shall be made by the approval authority that granted the licence to operate the simulation tool based on proposals from the vehicle manufacturer.
Only vehicles with one driven axle shall be selected for verification test.
It is recommended to include in each verification test relevant data set engine, axle and transmission with highest sales numbers per manufacturer. The components, separate technical units or systems may be tested all in one vehicle or in different vehicles, under the condition that each component is covered by minimum one verification test on one vehicle.
Vehicles which use standard values for CO 2 certification of their components, separate technical units or systems instead of measured values for the transmission and for the axle losses shall not be selected for the verification test as long as vehicles complying with the requirements in points a) to c) and using measured loss maps for these components, separate technical units or systems in the CO 2 certification, are produced.
The minimum number of different vehicles with different combinations of verification test relevant data sets to be tested by verification test per year shall be based on the sales numbers of the vehicle manufacturer as set out in Table 1:
Table 1 | |
Determination of the minimum number of vehicles to be tested by the vehicle manufacturer | |
Number of vehicles to be tested | Verification testing procedure relevant vehicles produced/year |
---|---|
1 | 1- 25 000 |

The vehicle manufacturer shall finalize the verification test within a period of 10 months after the date of selection of the vehicle for the verification test.
Each vehicle for the verification test shall be in series conditions as typically delivered to the customer. No changes in hardware such as lubricants or in the software such as auxiliary controllers are allowed.
Run in of the vehicle is not mandatory. If the total mileage of the test vehicle is less than 15 000 km, an evolution coefficient for the test result shall be applied as defined in point 7. The total mileage of the test vehicle shall be the odometer reading at start of the fuel consumption measurement. The maximum mileage for the verification testing procedure shall be 20 000 km.
All lubricants shall be in line with the series configuration of the vehicle.
For the fuel consumption measurement as described in point 6.1.5, reference fuel as set out in point 3.2 of Annex V shall be used.
The fuel tank shall be full at start of the fuel consumption measurement run.
All laboratory reference measurement equipment, used for calibration and verification, shall be traceable to national (international) standards. The calibration laboratory shall comply with the requirements of ISO 9000 series and either ISO/TS 16949 or ISO/IEC 17025.
The direct torque at all driven axles shall be measured with one of the following measurement systems fulfilling the requirements listed in Table 2:
hub torque meter;
rim torque meter;
half-shaft torque meter.
The calibrated range shall be at least 10 000 Nm; the measurement range shall cover the entire range of torque occurring during the verification testing procedure of the tested vehicle.
The drift shall be measured during the verification test described in point 6 by zeroing the torque measurement system in accordance with point 6.1.5 after the pre-conditioning phase by lifting the axle and measuring the torque at lifted axle directly after the verification test again.
For a valid test result a maximum drift of the torque measurement system over the verification testing procedure of 150 Nm (sum of both wheels) shall be proven.
The vehicle speed shall be used for possible plausibility checks of the gear signal later on and shall be based on the CAN signal.
The engaged gear does not need to be measured but shall be calculated by the simulation tool based on measured engine speed, the vehicle speed and the tyre dimensions and transmission ratios of the vehicle in accordance with point 7. The gear position may be provided also from the CAN signal to check possible deviations from the gear position calculated by the simulation tool. In case of deviations of the gear position in more than 5 % of the test duration, the reasons for the deviation shall be investigated and reported by the vehicle manufacturer. The input data on gear position shall be used in the simulation tool to compute the gear dependent losses in the gear box. The engine speed shall be taken by the simulation tool from the input data as defined in point 5.4.
The signal from the connection with the vehicle electronic control unit via the open on-board diagnostic interface shall be used to measure the engine speed. Alternative measurement systems are allowed if they fulfil the requirements set out in Table 2.
The measurement system for the rotational speed of left and right wheel at the driven axle for the assessment of the power demand at the wheels as input to the simulation tool for the verification test simulation shall fulfil the requirements set out in Table 2.
The CAN signal for the fan speed may be used, if available. Alternatively an external sensor fulfilling the requirements set out in Table 2 may be used.
The fuel consumed shall be measured on-board with a measurement device reporting the total amount of fuel consumed in kilograms. The fuel measurement system shall be based on one of the following measurement methods:
Measurement of fuel mass. The fuel measuring device shall fulfil the accuracy requirements set out in Table 2 for the fuel mass measurement system.
