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

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

(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)

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 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 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 CO 2 -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

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 i.

To ensure that the same fuel is used for all testruns performed for the purpose of certification of one specific engine CO 2 -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.

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 CO 2 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

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.

4.3 Testruns

4.3.1 Engine full load curve

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.

4.3.2 Engine motoring curve

The recording of the engine motoring curve in accordance with this paragraph shall be omitted for all other engines except the CO 2 -parent engine of the engine CO 2 -family defined in accordance with Appendix 3. In accordance with paragraph 6.1.3 the engine motoring curve recorded for the CO 2 -parent engine of the engine CO 2 -family shall also be applicable to all engines within the same engine CO 2 -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 ±2K.

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..

4.3.5 Fuel consumption mapping cycle (FCMC)

The fuel consumption mapping cycle (FCMC) in accordance with this paragraph shall be omitted for all other engines except the CO 2 -parent engine of the engine CO 2 -family. The fuel map data recorded for the CO 2 -parent engine of the engine CO 2 -family shall also be applicable to all engines within the same engine CO 2 -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.

4.3.5.1 Handling of interruptions during the FCMC

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:

(1)

the procedure shall be continued as described in paragraph 4.3.5.1.1

(2)

the whole FCMC shall be repeated in accordance with paragraphs 4.3.5.4 and 4.3.5.5

4.3.5.1.1 Provisions for continuing the FCMC

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.

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 CO 2 -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 CO 2 -parent engine of the engine CO 2 -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 n 57 shall be determined by the following equation:

n 57 = 0.565 x (0.45 x n lo + 0.45 x n pref + 0.1 x n hi − n idle ) x 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 = n 57 – 0.05 x (n 95h – n idle )

(3)

Base engine speed 3: n B = n 57 + 0.08 x (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)

dn 44 = ABS(dn idleA_44 – dn B95h_44 )

(2)

dn 35 = ABS(dn idleA_35 – dn B95h_35 )

(3)

dn 53 = 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 dn 44 , dn 35 and dn 53 in accordance with the following provisions:

(1)

If dn 44 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 dn 35 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 dn 53 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.

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 CO 2 -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.

If the first target setpoint is reached within less than 46 seconds, the remaining time up to 46 seconds shall be used for stabilization.

4.3.5.5 Test sequence

The test sequence consists of steady state target setpoints with defined engine speed and torque at each target setpoint in accordance with paragraph 4.3.5.2 and defined ramps to move from one target setpoint to the next.

The highest target torque setpoint at each target engine speed shall be operated with maximum operator demand.

The first target setpoint is defined at the highest target engine speed setpoint and highest target torque setpoint.

The following steps shall be performed to cover all target setpoints:

(1)

The engine shall be operated for 95±3 seconds at each target setpoint. The first 55±1 seconds at each target setpoint are considered as a stabilization period,. During the following period of 30±1 seconds the engine speed mean value shall be controlled as follows:
(a) The engine speed mean value shall be held at the target engine speed setpoint within ±1 percent of the highest target engine speed.

(b) Except for the points at full load, the engine torque mean value shall be held at the target torque setpoint within a tolerance of ±20 Nm or ±2 percent of the overall maximum torque, T max_overall , whichever is greater.

The recorded values in accordance with paragraph 4.3.5.3 shall be stored as

averaged value over the period of 30±1 seconds. The remaining period of 10±1

seconds may be used for data post-processing and storage if necessary. During this

period the engine target setpoint shall be kept.

(2)

After the measurement at one target setpoint is completed, the target value for
-1

engine speed shall be kept constant within ±20 min of the target engine speed setpoint and the target value for torque shall be decreased linearly within 20±1 seconds to match the next lower target torque setpoint. Then the measurement

shall be performed according to subpoint (1).

(3)

After the zero torque setpoint has been measured in subpoint (1), the target engine speed shall be decreased linearly to the next lower target engine speed setpoint while at the same time the target torque shall be increased linearly to the highest target torque setpoint at the next lower target engine speed setpoint within 20 to 46 seconds. If the next target setpoint is reached within less than 46 seconds, the remaining time up to 46 seconds shall be used for stabilization. Then the measurement shall be performed by starting the the stabilization procedure according to subpoint (1) and afterwards the target torque setpoints at constant target engine speed shall be adjusted according to subpoint (2).

Run-in of newly manufactured engines

5.1 The tests shall be carried out on newly manufactured engines taken from the series production which have a maximum run-in time of 15 hours before the testrun for the verification of conformity of the certified CO 2 emissions and fuel consumption related properties in accordance with paragraph 4 of this Appendix is started.

5.2 At the request of the manufacturer, the tests may be carried out on engines which have been run-in up to a maximum of 125 hours. In this case, the running-in procedure shall be conducted by the manufacturer who shall not make any adjustments to those engines.

5.3 When the manufacturer requests to conduct a running-in procedure in accordance with point 5.2 of this Appendix it may be carried out on either of the following:

a.

all the engines that are tested

b.
newly produced engine, with the determination of an evolution coefficient as follows:
- A.
  
  The specific fuel consumption shall be measured over the WHSC test once on the newly manufactured engine with a maximum runin time of 15 hours in accordance with point 5.1 of this Appendix and in the second test before the maximum of 125 hours set in point 5.2 of this Appendix on the first engine tested.

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
  -1
  
  be held within ±5 min 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 o 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
  o
  
  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
  -1

which the actual engine speed shall be held within ±5 min 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

o

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
o

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.

The actual fan constant shall be calculated from the measurement data according to the following equation:

C = MD fan _ disengage − MD fan _ engage i ⋅ 10 6

( n 2 2 fan _ engage − n fan _ disengage )

where:

C i fan constant at certain engine speed

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 -1 fan_disengage fan speed with fan disengaged min )

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 2 fan = C fan ⋅ n fan ⋅ 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. This mechanical power and the corresponding engine torque shall be taken into account in accordance with paragraph 3.1.2.

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 -1 95h are copied to engine speed (n 95h + 500 min ) 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 x (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 x 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
