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)

The engine coolant flow rate (or alternatively the pressure differential 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 CO₂-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 should be kept resonably 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.

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

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.

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 3 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.

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.

When the highest target torque setpoint at the particular target engine speed setpoint where the interruption occurred is reached, the recording of measurement values shall be continued from that point on in accordance with the test sequence specified in paragraph 4.3.5.5.

4.3.5.2 Grid of target setpoints

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 CO_2-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.

4.3.5.2.1 Definition of target engine speed setpoints

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 n_idle, n_lo, n_pref, n_95h and n_hi 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.

The engine speed n₅₇ shall be determined by the following equation:

n₅₇ = 0,565 × (0,45 × n_lo + 0,45 × n_pref + 0,1 × n_hi – n_idle) × 2,0327 + n_idle

The 4 base target engine speed setpoints are defined as follows:

(1)

Base engine speed 1: n_idle

(2)

Base engine speed 2: n_A = n₅₇ – 0,05 × (n_95h – n_idle)

(3)

Base engine speed 3: n_B = n₅₇ + 0,08 × (n_95h – n_idle)

(4)

Base engine speed 4: n_95h

The potential distances between the speed setpoints shall be determined by the following equations:

(1)

dn_{idleA_44} = (n_A – n_idle) / 4

(2)

dn_{B95h_44} = (n_95h – n_B) / 4

(3)

dn_{idleA_35} = (n_A – n_idle) / 3

(4)

dn_{B95h_35} = (n_95h – n_B) / 5

(5)

dn_{idleA_53} = (n_A – n_idle) / 5

(6)

dn_{B95h_53} = (n_95h – n_B) / 3

The absolute values of potential deviations between the two sections shall be determined by the following equations:

(1)

dn₄₄ = ABS(dn_{idleA_44} – dn_{B95h_44})

(2)

dn₃₅ = ABS(dn_{idleA_35} – dn_{B95h_35})

(3)

dn₅₃ = ABS(dn_{idleA_53} – dn_{B95h_53})

The 6 additional target engine speed setpoints shall be determined based on the smallest of the three values dn₄₄, dn₃₅ and dn₅₃ in accordance with the following provisions:

(1)

If dn₄₄ is the smallest of the three values, 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.

(2)

If dn₃₅ is the smallest of the three values, 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.

(3)

If dn₅₃ is the smallest of the three values, 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.

Definition of speed setpoints

4.3.5.2.2 Definition of target torque setpoints

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 T_{max_overall}). The 9 additional target torque setpoints are determined by dividing the range from zero torque to overall maximum torque, T_{max_overall}, into 10 equidistant sections.

All 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 with the full load torque value at this particular target engine speed setpoint. Figure 2 exemplarily illustrates the definition of the target torque setpoints.

7.1 The specific fuel consumption over the WHSC, SFC_WHSC, shall be determined in accordance with paragraph 5.3.3 of this Annex from the testruns performed in accordance with paragraph 4 of this Appendix. At the request of the manufacturer the specific fuel consumption value determined shall be modified by applying the provisions defined in points 5.3 to 5.6 of this Appendix.

7.2 If market fuel was used during testing in accordance with point 1.4 of this Appendix, the specific fuel consumption over the WHSC, SFC_WHSC, determined in point 7.1 of this Appendix shall be adjusted to a corrected value, SFC_WHSC,corr, in accordance with paragraph 5.3.3.1 of this Annex.

7.3 If reference fuel was used during testing in accordance with point 1.4 of this Appendix the special provisions defined in paragraph 5.3.3.2 of this Annex shall be applied to the value determined in point 7.1 of this Appendix.

7.4 The measured emission of gaseous pollutants over the WHSC performed in accordance with paragraph 4 shall be adjusted by application of the appropriate deterioration factors (DF's) for that engine as recorded in the Addendum to the EC type-approval certificate granted in accordance with Commission Regulation (EU) No 582/2011.

8. Limit for conformity of one single test

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) + 3 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) + 4 percent.

9.4 If neither a pass nor a fail decision is reached, the manufacturer may at any time decide to stop testing. In that case a fail decision is recorded.

Appendix 5 Determination of power consumption of engine components

1. Fan

The engine torque shall be measured at engine motoring with and without fan engaged with the following procedure:

(i)

Install the fan according to product instruction before the test starts.

(ii)

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).

(iii)

Stabilization phase: After the warm-up or optional warmup 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} < 0,25 * 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.

(iv)

Measurement phase: During the following period of 60 ± 1 seconds the actual engine speed shall be held within ± 2 min^{– 1} of n_pref 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.

(v)

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)

(vi)

Stabilization phase: After the optional warm-up is completed the engine shall be operated with minimum operator demand (motoring) at engine speed n_pref for 130 ± 2 seconds with the fan engaged (n_{fan_engage} > 0,9 * 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.

(vii)

Measurement phase: During the following period of 60 ± 1 seconds the actual engine speed shall be held within ± 2 min^{– 1} of n_pref 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.

(viii)

Steps (iii) to (vii) shall be repeated at engine speeds n_95h and n_hi instead of n_pref, 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.

(ix)

If the standard deviation of all calculated C_i according to the equation below at the three speeds n_pref, n_95h and n_hi 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.

MD_{fan_disengage}

measured engine torque at motoring with fan disengaged (Nm)

MD_{fan_engage}

measured engine torque at motoring with fan engaged (Nm)

n_{fan_engage}

fan speed with fan engaged (min^{– 1})

n_{fan_disengage}

fan speed with fan disengaged min^{– 1})

r_fan

fan ratio

If the standard deviation of all calculated C_i at the three speeds n_pref, n_95h and n_hi is less than 3 %, an average value C_avg-fan determined over the three speeds n_pref, n_95h and n_hi shall be used for the fan constant.

If the standard deviation of all calculated C_i at the three speeds n_pref, n_95h and n_hi is equal or higher than 3 %, individual values determined for all engine speeds according to point (ix) shall be used for the fan constant C_ind-fan,i. The value of the fan constant for the actual engine speed C_fan, shall be determined by linear interpolation between the individual values C_ind-fan,i of the fan constant.

The engine torque for driving the fan shall be calculated according to the following equation:

M_fan = C_fan · n_fan ² · 10^{– 6}

where:

M_fan

engine torque for driving fan (Nm)

C_fan

fan constant C_avg-fan or C_ind-fan,i corresponding to n_engine

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.

2. Electric components/equipment

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.

Appendix 8 Important evaluation steps and equations of the engine pre-processing tool

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:

1. Reading of input files and automatic check of input data

1.1 Check of requirements for input data according to the definitions in paragraph 6.1 of this Annex

1.2 Check of requirements for recorded FCMC data according to the definitions in paragraph 4.3.5.2 and subpoint (1) of paragraph 4.3.5.5 of this Annex

2. Calculation of characteristic engine speeds from full load curves of parent engine and actual engine for certification according to the definitions in paragraph 4.3.5.2.1 of this Annex

3. Processing of fuel consumption (FC) map

3.1 FC values at n_idle are copied to engine speed (n_idle – 100 min^{– 1}) in the map

3.2 FC values at n_95h are copied to engine speed (n_95h + 500 min^{– 1}) in the map

3.3 Extrapolation of FC values at all engine speed setpoints to a torque value of (1.1 times T_{max_overall}) by using least squares linear regression based on the 3 measured FC points with the highest torque values at each engine speed setpoint in the map

3.4 Adding of FC = 0 for interpolated motoring torque values at all engine speed setpoints in the map

3.5 Adding of FC = 0 for minimum of interpolated motoring torque values from subpoint (3.4) minus 100 Nm at all engine speed setpoints in the map

4. Simulation of FC and cycle work over WHTC and respective subparts for actual engine for certification

4.1. WHTC reference points are denormalized using the full load curve input in originally recorded resolution

4.2. FC is calculated for WHTC denormalized reference values for engine speed and torque from subpoint 4.1

4.3. FC is calculated with engine inertia set to 0

4.4. FC is calculated with standard PT1-function (as in main vehicle simulation) for engine torque response active

4.5. FC for all motoring points is set to 0

4.6. FC for all non-motoring engine operation points is calculated from FC map by Delaunay interpolation method (as in main vehicle simulation)

4.7. Cycle work and FC are calculated according to equations defined in paragraphs 5.1 and 5.2 of this Annex

4.8. Simulated specific FC values are calculated analogous to equations defined in paragraphs 5.3.1 and 5.3.2 of this Annex for measured values

5. Calculation of WHTC correction factors

5.1. Measured values from input to pre-processing tool and simulated values from point (4) are used in accordance with the equations in points (5.2) to (5.4)

5.2. CF_Urban = SFCmeas,_Urban/SFCsimu,_Urban

5.3. CF_Rural = SFCmeas,_Rural/SFCsimu,_Rural

5.4. CF_MW = SFCmeas,_MW/SFCsimu,_MW

5.5. In case that the calculated value for a correction factor is lower than 1, the respective correction factor is set to 1

6. Calculation of cold-hot emission balancing factor

6.1. This factor is calculated in accordance with the equation in point (6.2)

6.2. BF_cold-hot = 1 + 0,1 × (SFC_meas,cold – SFC_meas,hot)/SFC_meas,hot

6.3. In case that the calculated value for this factor is lower than 1, the factor is set to 1

7. Correction of FC values in FC map to standard NCV

7.1. This correction is performed in accordance with the equation in point (7.2)

7.2. FC_corrected = FC_measured,map × NCV_meas/NVC_std

7.3. FC_measured,map shall be the FC value in the FC map input data processed in accordance with point (3)

7.4. NCV_meas and NVC_std shall be defined in accordance with paragraph 5.3.3.1 of this Annex

7.5. In the case that reference fuel of the type B7 (Diesel / CI) in accordance with paragraph 3.2 of this Annex was used during testing, the correction in accordance with points (7.1) to (7.4) is not performed.

8. Converting of engine full load and motoring torque values of the actual engine for certification to a logging frequency of the engine speed of 8 min^{– 1}

8.1. The conversion is performed by arithmetical averaging over intervals of ± 4 min^{– 1} of the given setpoint for the output data based on the full load curve input in originally recorded resolution
