5. Hydraulically and mechanically driven axles U.K.

In case of vehicles equipped with:

(a)

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;

(b)

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;

6. Gear dependent engine torque limits set by vehicle control U.K.

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.

7. Vehicle specific engine idling speed U.K.

7.1. The engine idling speed has to be declared in VECTO for each individual vehicle. This declared vehicle engine idling shall be equal or higher than specified in the engine input data approval. U.K.

[F2 8. Advanced driver assistance systems U.K.

8.1. The following types of advanced driver assistance systems, which are primarily aiming for reduction of fuel consumption and CO ₂ emissions, shall be declared in the input to the simulation tool: U.K.

8.1.1.

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.

8.1.2.

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.

8.1.3.

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.

8.1.4.

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:

(1)

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.

(2)

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.

(3)

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.

8.2. The eleven combinations of the advanced driver assistance systems as set out in Table 7 are input parameters into the simulation tool: U.K.

Table 7
Combinations of advanced driver assistance systems as input parameters into the simulation tool
Combination No	Engine stop-start during vehicle stops	Eco-roll without engine stop-start	Eco-roll with engine stop-start	Predictive cruise control

11	yes	no	yes	yes

8.3. Any advanced driver assistance system declared in the input into the simulation tool shall by default be set to fuel economy mode after each key-off/key-on cycle. U.K.

8.4. If an advanced driver assistance system is declared in the input into the simulation tool, it shall be possible to verify the presence of such a system based on real world driving and the system definitions as set out in point 8.1. If a certain combination of systems is declared, also the interaction of functionalities (e.g. predictive cruise control plus eco-roll with engine stop-start) shall be demonstrated. In the verification procedure it shall be taken into consideration, that the systems need certain boundary conditions to be ‘ active ’ (e.g. engine at operation temperature for engine stop-start, certain vehicle speed ranges for PCC, certain ratios of road gradients with vehicle mass for eco-roll). The vehicle manufacturer needs to submit a functional description of boundary conditions when the systems are ‘ inactive ’ or their efficiency is reduced. The approval authority may request the technical justifications of these boundary conditions from the applicant for approval and assess them for compliance.] U.K.

3. General requirements U.K.

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.

3.1 Test conditions U.K.

All testruns performed for the purpose of certification of one specific engine CO_2-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.

3.1.1 Laboratory test conditions U.K.

The tests shall be conducted under ambient conditions meeting the following conditions over the whole testrun:

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.

3.1.4 Engines with charge air-cooling U.K.

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.

3.1.5 Engine cooling system U.K.

(1)

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.

(2)

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).

(3)

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).

(4)

[F1 The 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.]

(5)

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.

(6)

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.

3.2 Fuels U.K.

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.

[F1 The 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.

[F2 For 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 lubricating oil for all testruns performed in accordance with this Annex shall be a commercially available oil with unrestricted manufacturer approval under normal in-service conditions as defined in paragraph 4.2 of Annex 8 to UN/ECE Regulation 49 Rev.06. Lubricants for which the usage is restricted to certain special operation conditions of the engine system or having an unusually short oil change interval shall not be used for the purpose of testruns in accordance with this Annex. The commercially available oil shall not be modified by any means and no additives shall be added.

All testruns performed for the purpose of certification of the CO₂ emissions and fuel consumption related properties of one specific engine CO_2-family shall be performed with the same type of lubricating oil.

3.4 Fuel flow measurement system U.K.

All fuel flows consumed by the whole engine system shall be captured by the fuel flow measurement system. Additional fuel flows not directly supplied to the combustion process in the engine cylinders shall be included in the fuel flow signal for all testruns performed. Additional fuel injectors (e.g. cold start devices) not necessary for the operation of the engine system shall be disconnected from the fuel supply line during all testruns performed.

ANNEX VI U.K. VERIFYING TRANSMISSION, TORQUE CONVERTER, OTHER TORQUE TRANSFERRING COMPONENT AND ADDITIONAL DRIVELINE COMPONENT DATA

1. Introduction U.K.

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.

2. Definitions U.K.

For the purposes of this Annex the following definitions shall apply:

(1)

‘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;

(2)

‘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 = n_in/n_out );

(3)

‘Ratio coverage’ means the ratio of the largest to the smallest forward gear ratios in a transmission: φ_tot = i_max/i_min ;

(4)

‘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;

(5)

‘Main section’ means the sub-transmission that has the largest number of forward gears in a compound transmission;

(6)

‘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;

(7)

‘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;

(8)

‘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);

(9)

‘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;

(10)

‘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);

(11)

‘Synchroniser’ means a type of tooth clutch where a friction device is used to equalise the speeds of the rotating parts to be engaged;

(12)

‘Gear mesh efficiency’ means the ratio of output power to input power when transmitted in a forward gear mesh with relative motion;

(13)

‘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;

(14)

‘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;

(15)

‘Power take-off drive mechanism’ means a device in a transmission that allows the installation of a power take-off (PTO);

(16)

‘Lock-up clutch’ means a friction clutch in a hydrodynamic torque converter; it can connect the input and output sides, thereby eliminating the slip;

(17)

‘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;

(18)

‘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);

(19)

‘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;

(20)

‘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;

(21)

‘Retarder’ means an auxiliary braking device in a vehicle powertrain; aimed for permanent braking;

(22)

‘Case S’ means the serial arrangement of a torque converter and the connected mechanical parts of the transmission;

(23)

‘Case P’ means the parallel arrangement of a torque converter and the connected mechanical parts of the transmission (e.g. in power split installations);

(24)

‘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);

(25)

‘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;

(26)

3.4.9. The torque loss map data shall be formatted and saved as specified in Appendix 12 to this Annex. U.K.

4. Torque converter (TC) U.K.

The torque converter characteristics to be determined for the simulation tool input consist of T_{pum 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:

Case S

:

TC and mechanical transmission parts in serial arrangement

Case P

:

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:

(i)

Option A: measurement at constant input speed

(ii)

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 T_pum 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.

5. Other torque transferring components (OTTC) U.K.

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.

5.1. Methods for establishing retarder drag losses U.K.

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.

Table 2

Retarder rotor speeds

Configuration	Speed reference	Retarder rotor speed calculation
A. Engine Retarder	Engine Speed	nretarder = nengine * istep-up
B. Transmission Input Retarder	Transmission Input Shaft Speed	nretarder = ntransm.input * istep-up = ntransm.output * itransm * istep-up
C. Transmission Output Retarder or Propshaft Retarder	Transmission Output Shaft Speed	nretarder = ntransm.output * istep-up

where:

i_step-up

=

step-up ratio = retarder rotor speed/drive part speed

i_transm

=

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:

(1)

Measurement on the retarder as a stand-alone unit

(2)

Measurement in combination with the transmission

5.1.1. General requirements U.K.

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.

5.1.2. Run-in U.K.

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.

5.1.3.4. Oil or water quality U.K.

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).

5.1.3.5. Oil viscosity U.K.

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).

5.1.3.6. Oil or water level U.K.

The oil/water level shall meet the nominal specifications for the retarder.

5.1.4. Installation U.K.

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°.

Standard torque loss values - Transmission U.K.

Calculated fallback values based on the maximum rated torque of the transmission:

• The torque loss T_l,in related to the input shaft of the transmission shall be calculated by

  

  where:

  T_l,in

  =

  Torque loss related to the input shaft [Nm]

  T_dx

  =

  Drag torque at x rpm [Nm]

  T_addx

  =

  Additional angle drive gear drag torque at x rpm [Nm]

  (if applicable)

  n_in

  =

  Speed at the input shaft [rpm]

  f_T

  =

  1-η

  η

  =

  efficiency

  f_T

  =

  0,01 for direct gear, 0,04 for indirect gears

  f_{T_add}

  =

  0,04 for angle drive gear (if applicable)

  T_in

  =

  Torque at the input shaft [Nm]

• For transmissions with tooth shift clutches (Synchronised Manual Transmissions (SMT), Automated Manual Transmissions or Automatic Mechanically engaged Transmissions (AMT) and Dual Clutch Transmissions (DCT)) the drag torque T_dx is calculated by

  

  where:

  T_max,in

  =

Appendix 9

Generic model – torque converter U.K.

Generic torque converter model based on standard technology:

For the determination of the torque converter characteristics a generic torque converter model depending on specific engine characteristics may be applied.

The generic TC model is based on the following characteristic engine data:

n_rated

=

Maximum engine speed at maximum power (determined from the engine full-load curve as calculated by the engine pre-processing tool) [rpm]

T_max

=

Maximum engine torque (determined from the engine full-load curve as calculated by the engine pre-processing tool) [Nm]

Thereby the generic TC characteristics are valid only for a combination of the TC with an engine sharing the same specific characteristic engine data.

Description of the four-point model for the torque capacity of the TC:

Generic torque capacity and generic torque ratio:

Figure 1

Generic torque capacity

Figure 2

Generic torque ratio

where:

T_P1000

=

Pump reference torque; [Nm]

v

=

Speed ratio; [-]

μ

=

Torque ratio; [-]

v_s

=

Speed ratio at overrun point; [-]

For TC with rotating housing (Trilock-Type) v_s typically is 1. For other TC concepts, especially power split concepts, v_s may have values different from 1.

v_c

=

Speed ratio at coupling point; [-]

v₀

=

Stall point; v ₀ = 0 [rpm]

v_m

=

Intermediate speed ratio; [-]

The model requires the following definitions for the calculation of the generic torque capacity:

• Stall point:

  • Stall point at 70 % nominal engine speed.

  • Engine torque in stall point at 80 % maximum engine torque.

  • Engine/Pump reference torque in stall point:

    

• Intermediate point:

  • Intermediate speed ratio v_m = 0,6 * v_s

  • Engine/pump reference torque in intermediate point at 80 % of reference torque in stall point:

    

• Coupling point:

  • Coupling point at 90 % overrun conditions: v_c = 0,90 * v_s

  • Engine/pump reference torque in clutch point at 50 % of reference torque in stall point:

    

• Overrun point:

  • Reference torque at overrun conditions = v_s :

    

The model requires the following definitions for the calculation of the generic torque ratio:

• Stall point:

  • Torque ratio at stall point v₀ = v_s = 0:

    

• Intermediate point:

  • Linear interpolation between stall point and coupling point

• Coupling point:

  • Torque ratio at coupling point v_c = 0,9 * v_s :

    

• Overrun point:

  • Torque ratio at overrun conditions = v_s :

    

• Efficiency:

  n = μ * v

Linear interpolation between the calculated specific points shall be used.

ANNEX VII U.K. VERIFYING AXLE DATA

1. Introduction U.K.

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.

2. Definitions U.K.

For the purposes of this Annex the following definitions shall apply:

(1)

‘Single reduction axle (SR)’ means a driven axle with only one gear reduction, typically a bevel gear set with or without hypoid offset.

(2)

‘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.

(3)

‘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.

(4)

‘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.

(5)

‘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).

(6)

‘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.

(7)

‘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.

(8)

‘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.

(9)

‘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.

(10)

‘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.

(11)

‘Oil type viscosity grade’ means a viscosity grade as defined by SAE J306.

(12)

‘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.

(13)

‘Axle line’ means a group of axles that share the same basic axle-function as defined in the family concept.

(14)

‘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.

(15)

‘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.

(16)

‘Mirror inverted axle casing’ means the axle casing is mirrored regarding to the vertical plane.

(17)

‘Axle input’ means the side of the axle on which the torque is delivered to the axle.

(18)

‘Axle output’ means the side(s) of the axle where the torque is delivered to the wheels.

3. General requirements U.K.

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.

3.1 Run-in U.K.

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.

3.1.1 Only factory fill oil shall be used for the run-in procedure. The oil used for the run-in shall not be used for the testing described in paragraph 4. U.K.

3.1.2 The speed and torque profile for the run-in procedure shall be specified by the manufacturer. U.K.

3.1.3 The run-in procedure shall be documented by the manufacturer with regard to run-time, speed, torque and oil temperature and reported to the approval authority. U.K.

3.1.4 The requirements for the oil temperature (4.3.1), measurement accuracy (4.4.7) and test set-up (4.2) do not apply for the run-in procedure. U.K.

4. Testing procedure for axles U.K.

4.1 Test conditions U.K.

4.1.1 Ambient temperature U.K.

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.

4.1.2 Oil temperature U.K.

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.

4.1.3 Oil quality U.K.

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.

4.1.4 Oil viscosity U.K.

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.

4.1.5 Oil level and conditioning U.K.

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.

4.2 Test set-up U.K.

4.2.2 Installation of torque meters U.K.

4.2.2.1 For a test setup with two electric machines, the torque meters shall be installed on the input flange and on one wheel end while the other one is locked. U.K.

4.2.2.2 For a test setup with three electric machines, the torque meters shall be installed on the input flange and on each wheel end. U.K.

4.2.2.3 Half shafts of different lengths are permitted in a two machine set-up in order to lock the differential and to ensure that both wheel ends are turning. U.K.

4.2.3 Test set-up ‘Type A’ U.K.

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 i_para cannot be lower than 10 %.

Figure 1 Example of Test set-up ‘Type A’ U.K.

4.2.4 Test set-up ‘Type B’ U.K.

Any other test set-up configuration is called test set-up Type B. The maximum influence of parasitic loads i_para for those configurations shall be set to 100 %.

Lower values for i_para may be used in agreement with the approval authority.

4.3 Test procedure U.K.

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. [F1 The 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.]

4.3.1 Measurement equipment U.K.

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.

4.3.3 Torque range: U.K.

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.

4.3.3.1 The manufacturer may extend the measurement up to 20 kNm output torque by means of linear extrapolation of torque losses or by performing measurements up to 20 kNm output torque with steps of 2 000 Nm. For this additional torque range another torque sensor at the output side with a maximum torque of 20 kNm (2-machine layout) or two 10 kNm sensors (3-machine layout) shall be used. U.K.

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.

Calculation of the standard torque loss U.K.

The standard torque losses for axles are shown in Table 1. The standard table values consist of the sum of a generic constant efficiency value covering the load dependent losses and a generic basic drag torque loss to cover the drag losses at low loads.

Tandem axles shall be calculated using a combined efficiency for an axle including drive-thru (SRT, HRT) plus the matching single axle (SR, HR).

Table 1

Generic efficiency and drag loss

Basic function	Generic efficiencyη	Drag torque(wheel side)Td0 = T0 + T1 * igear
Single reduction axle (SR)	0,98	T0 = 70 Nm T1 = 20 Nm
Single reduction tandem axle (SRT) / single portal axle (SP)	0,96	T0 = 80 Nm T1 = 20 Nm
Hub reduction axle (HR)	0,97	T0 = 70 Nm T1 = 20 Nm
Hub reduction tandem axle (HRT)	0,95	T0 = 90 Nm T1 = 20 Nm

The basic drag torque (wheel side) T_d0 is calculated by

T_d0 = T₀ + T₁ * i_gear

using the values from Table 1.

The standard torque loss T_loss,std on the wheel side of the axle is calculated by

Appendix 4

Family Concept U.K.

1. The applicant for a certificate shall submit to the approval authority an application for a certificate for an axle family based on the family criteria as indicated in paragraph 3. U.K.

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.

2. Special cases U.K.

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.

Appendix 5

Air drag family for trucks U.K.

1. General U.K.

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.

2. Special cases U.K.

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.

F3 3. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . U.K.

4. Parameter defining the air drag family: U.K.

4.1. Vehicles are allowed to be grouped within a family if the following criteria are fulfilled: U.K.

(a)

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.

(b)

Same roof height in vertical Z. All members of the family stay within a range of ± 10 mm to the parent vehicle.

(c)

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.

Figure 1 Family definition U.K.

4.2. An air drag family consist of testable members and vehicle configurations which can not be tested in accordance with this regulation. U.K.

4.3. Testable members of a family are vehicle configurations, which fulfil the installation requirements as defined in 3.3 in the main part of this Annex. U.K.

5. Choice of the air drag parent vehicle U.K.

5.1. The parent vehicle of each family shall be selected according to the following criteria: U.K.

5.2. The vehicle chassis shall fit to the dimensions of the standard body or semi-trailer as defined in Appendix 4 of this Annex. U.K.

5.4. The applicant for a certificate shall be able to demonstrate that the selection of the parent vehicle meets the provisions as stated in 5.3 based on scientific methods e.g. CFD, wind tunnel results or good engineering practice. This provision applies for all vehicle variants which can be tested by the constant speed procedure as described in this Annex. Other vehicle configurations (e.g. vehicle heights not in accordance with the provisions in Appendix 4, wheel bases not compatible with the standard body dimensions of Appendix 5) shall get the same air drag value as the testable parent within the family without any further demonstration. As tires are considered as part of the measurement equipment, their influence shall be excluded in proving the worst case scenario. U.K.

[F1 5.5. The declared value C _d ·A _declared can be used for creation of families in other vehicle classes if the family criteria in accordance with point 5 of this Appendix are met based on the provisions given in Table 16.] U.K.

ii.

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.

2. A vehicle fails the conformity of the certified CO₂ emissions and fuel consumption related properties test if the measured C_d A_cr (0) value is higher than the C_d · A_declared value declared for the parent vehicle plus 7,5 % tolerance margin. If a first test fails, up to two additional tests at different days with the same vehicle may be performed. [F1 Where the measured C _d A _cr (0) value of all performed tests is higher than the C _d ·A _declared value declared for the parent vehicle plus 7,5 % tolerance margin, Article 23 of this Regulation shall apply.] U.K.

[F2 For 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.]

3. The number of vehicles to be tested for conformity with the certified CO₂ emissions and fuel consumption related properties per year of production shall be determined based on Table 17. U.K.

Table 17
Number of vehicles to be tested for conformity with the certified CO2 emissions and fuel consumption related properties per year of production

1. Introduction U.K.

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.
