‘Approval of a vehicle’ means the approval of a vehicle type with regard to the measurement of energy consumption (fuel or electric energy);

2.2.

‘Vehicle type’ means a category of power driven vehicles which do not differ in such essential respects as body, power train, transmission, traction battery (if applicable), tyres and unladen mass;

2.3.

‘Unladen mass’ means the mass of the vehicle in running order without crew, passengers or load, but with the fuel tank full (if any), cooling liquid, service and traction batteries, oils, onboard charger, portable charger, tools and spare wheel, whatever is appropriate for the vehicle considered and if provided by the manufacturer of the vehicle;

2.4.

‘Reference mass’ means the unladen mass of the vehicle increased by a uniform figure of 100 kg;

2.5.

‘Maximum mass’ means the technically permissible maximum mass declared by the manufacturer (this mass may be greater than the maximum mass authorised by the national administration);

2.6.

‘Test mass’ for the pure electric vehicles, means the ‘reference mass’ for the category M

vehicles and the unladen mass plus half the full load for the category N

vehicles;

2.7.

‘Lorry’ means a motor vehicle of category N

which is designed and constructed exclusively or principally for conveying goods;

2.8.

‘Van’ means a lorry with the cab integrated into the body;

2.9.

‘Cold start device’ means a device which enriches the air/fuel mixture of the engine temporarily, to assist starting;

2.10.

‘Starting aid’ means a device which assists engine starting without enrichment of the air/fuel mixture, e.g. glow plug, changed injection timing, etc.;

2.11.

2.12.

‘Internal combustion engine vehicle’ means vehicle powered by an internal combustion engine only;

2.13.

‘Electric power train’ means a system consisting of one or more electric energy storage devices (e.g. a battery, electromechanical flywheel or super capacitor), one or more electric power conditioning devices and one or more electric machines that convert stored electric energy to mechanical energy delivered at the wheels for propulsion of the vehicle;

2.14.

‘Pure electric vehicle’ means vehicle powered by an electric power train only;

2.15.

‘Hybrid power train’ means a power train with at least two different energy converters and two different energy storage systems (on-board the vehicle) for the purpose of vehicle propulsion;

2.15.1.

‘Hybrid electric power train’ means a power train that, for the purpose of mechanical propulsion, draws energy from both of the following on-vehicle sources of stored energy/power:

— a consumable fuel

— an electrical energy/power storage device (e.g. battery, capacitor, flywheel/generator, etc.);

5.5. Interpretation of results

5.5.1. The CO

value or the value of electric energy consumption adopted as the type-approval value shall be the value declared by the manufacturer if the value measured by the technical service does not exceed the declared value by more than 4 per cent. The measured value can be lower without any limitations.

In the case of vehicles powered by an internal combustion engine only which are equipped with periodically regenerating systems as defined in paragraph 2.19, the results are multiplied by the factor K

obtained from Annex 10 before being compared to the declared value.

5.5.2. If the measured value of CO

or electric energy consumption exceeds the manufacturer’s declared CO

or electric energy consumption value by more than 4 per cent, then another test is run on the same vehicle.

When the average of the two test results does not exceed the manufacturer’s declared value by more than 4 per cent, then the value declared by the manufacturer is taken as the type-approval value.

5.5.3. If the average still exceeds the declared value by more than 4 per cent, a final test is run on the same vehicle. The average of the three test results is taken as the type-approval value.

6. MODIFICATION AND EXTENSION OF APPROVAL OF THE APPROVED TYPE

6.1. Every modification of the approved type shall be notified to the administrative department which approved the type. The department may then either:

6.1.1.

Consider that the modifications made are unlikely to have an appreciable adverse effect on the values of CO

and fuel consumption or electric energy consumption and that, in this case, the original approval will be valid for the modified vehicle type; or

6.1.2.

Require a further test report from the technical service responsible for conducting the tests according to conditions in paragraph 7 of this Regulation.

6.2. Confirmation or extension of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 4.3 to the Parties to the 1958 Agreement applying this Regulation.

6.3. The competent authority which grants the extension of the approval shall assign a series number for such an extension and inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in Annex 4 to this Regulation.

7.5. Extension of approval of vehicles of category N

1 within a family, if powered by an internal combustion engine only or by a hybrid electric power train

7.5.1. For vehicles of category N

that are approved as members of a vehicle family using the procedure in paragraph 7.6.2, the type-approval can be extended to vehicles from within the same family only if the technical service estimates that the fuel consumption of the new vehicle does not exceed the fuel consumption of the vehicle on which the family’s fuel consumption is based.

Approvals may also be extended to vehicles which:

(a) are up to 110 kg heavier than the family member tested, provided that they are within 220 kg of the lightest member of the family;

(b) have a lower overall transmission ratio than the family member tested due solely to a change in tyre sizes; and

7.5.2. For vehicles of category N

that are approved as members of a vehicle family using the procedure in paragraph 7.6.3, the type-approval can be extended to vehicles from within the same family without additional testing only if the technical service estimates that the fuel consumption of the new vehicle falls within the limits made up of those two vehicles in the family that have the lowest and the highest fuel consumption, respectively.

7.6. Approval of vehicles of category N

1 within a family, if powered by an internal combustion engine only or by a hybrid electric power train

Vehicles of category N

can be approved within a family as defined in paragraph 7.6.1 using one of the two alternative methods described in paragraphs 7.6.2 and 7.6.3.

7.6.1. N

vehicles may be grouped together into a family for the purposes of this Regulation if the following parameters are identical or within the specified limits:

7.6.1.1.

Identical parameters are:

(a) manufacturer and type as defined in Annex 4, item 2;

(b) engine capacity;

(d) fuel system type as defined in Annex 4, item 6.7.2.

7.6.1.2.

The following parameters have to be within the following limits:

(a) transmission overall ratios (no more than 8 per cent higher than the lowest) as defined in Annex 4, item 6.10.3;

(b) reference mass (no more than 220 kg lighter than the heaviest);

(d) engine power (no more than 10 per cent less than the highest value).

7.6.2. A vehicle family, as defined in paragraph 7.6.1, can be approved with CO

emission and fuel consumption data that are common to all members of the family. The technical service must select for testing the member of the family which the service considers to have the highest CO

emission. The measurements are performed as described in paragraph 5 and Annex 6, and the results according to the method described in paragraph 5.5 are used as type-approval values that are common to all members of the family.

7.6.3. Vehicles that are grouped in a family as defined in paragraph 7.6.1 can be approved with individual CO

emission and fuel consumption data for each of the family members. The technical service selects for testing the two vehicles, which the service considers to have the highest and the lowest CO

emissions respectively. The measurements are performed as described in paragraph 5 and Annex 6. If the manufacturer’s data for these two vehicles falls within the tolerance limits described in paragraph 5.5, the CO

emissions declared by the manufacturer for all members of the vehicle family can be used as type-approval values. If the manufacturer’s data do not fall within the tolerance limits, the results according to the method described in paragraph 5.5 are used as type-approval values and the technical service shall select an appropriate number of other family members for additional tests.

8. SPECIAL PROVISIONS

In the future, vehicles with special energy efficient technologies may be offered which could be submitted to complementary testing programmes. These would be specified at a later stage which can be claimed by the manufacturer in order to demonstrate the advantages of the solution.

9. CONFORMITY OF PRODUCTION

9.1. Vehicles approved according to this Regulation shall be so manufactured as to conform to the type-approved vehicle.

9.2. So as to verify that the conditions set out in paragraph 9.1 are complied with, appropriate production checks shall be carried out.

9.3. Vehicles powered by an internal combustion engine only

9.3.1. As a general rule, measures to ensure the conformity of production with regard to CO

emissions from vehicles are checked on the basis of the description in the type-approval certificate conforming to the model in Annex 4 to this Regulation.

The control of production conformity is based on an assessment made by the competent authority of the manufacturer’s auditing procedure in order to ensure conformity of the vehicle type with respect to the emission of CO

If the authority is not satisfied with the standard of the manufacturer’s auditing procedure, they may require that verification tests be carried out on vehicles in production.

9.3.1.1. If a measurement of the emissions of CO

must be carried out on a vehicle type that has had one or several extensions, the tests will be carried out on the vehicle(s) available at the time of the test (vehicle(s) described in the first document or in subsequent extensions).

9.3.1.1.1. Conformity of the vehicle for the CO

test.

9.3.1.1.1.1.

Three vehicles are randomly taken in the series and are tested according to the procedure as described in Annex 6.

9.3.1.1.1.2.

If the authority is satisfied with the production standard deviation given by the manufacturer, the tests are carried out according to paragraph 9.3.2.

If the authority is not satisfied with the production standard deviation given by the manufacturer, the tests are carried out according to paragraph 9.3.3.

9.3.1.1.1.3.

The production of a series is regarded as conforming or non-conforming, on the basis of tests on the three sampled vehicles, once a pass or fail decision is reached for CO

, according to the test criteria applied in the appropriate table.

If no pass or fail decision is reached for CO

, a test is carried out on an additional vehicle (see Figure 1).

9.3.1.1.1.4.

In the case of periodically regenerating systems as defined in paragraph 2.19, the results shall be multiplied by the factor K

obtained by the procedure specified in Annex 10 at the time when type-approval was granted.

At the request of the manufacturer, testing may be carried out immediately after a regeneration has been completed.

Figure 1

[Bild bitte in Originalquelle ansehen]

9.3.1.1.2. Notwithstanding the requirements of Annex 6, the tests will be carried out on vehicles which have not travelled any distance.

9.3.1.1.2.1.

However, at the request of the manufacturer, the tests will be carried out on vehicles which have been run-in a maximum of 15 000 km.

In this case, the running-in procedure will be conducted by the manufacturer who shall undertake not to make any adjustments to those vehicles.

9.3.1.1.2.2.

If the manufacturer asks to conduct a running-in procedure (‘x’ km, where x ≤ 15 000 km), it may be carried out as follows:

The emissions of CO

will be measured at zero and at ‘x’ km on the first tested vehicle (which can be the type-approval vehicle);

The evolution coefficient (EC) of the emissions between zero and ‘x’ km will be calculated as follows:

[Bild bitte in Originalquelle ansehen]

The value of EC may be less than 1.

The following vehicles will not be subjected to the running-in procedure, but their zero km emissions will be modified by the evolution coefficient, EC.

In this case, the values to be taken will be:

The value at ‘x’ km for the first vehicle;

The values at zero km multiplied by the evolution coefficient for the following vehicles.

9.3.1.1.2.3.

As an alternative to this procedure, the car manufacturer can use a fixed evolution coefficient, EC, of 0,92 and multiply all values of CO

measured at zero km by this factor.

9.3.1.1.2.4.

The reference fuels described in Annexes 10 and 10a to Regulation No 83 shall be used for this test.

9.3.2. Conformity of production when manufacturer’s statistical data is available.

9.3.2.1. The following sections describe the procedure to be used to verify the CO

conformity of production requirements when the manufacturer’s production standard deviation is satisfactory.

9.3.2.2. With a minimum sample size of three the sampling procedure is set so that the probability of a lot passing a test with 40 per cent of the production defective is 0,95 (producer’s risk = 5 per cent) while the probability of a lot being accepted with 65 per cent of the production defective is 0,1 (consumer’s risk = 10 per cent).

9.3.2.3. The following procedure is used (see Figure 1):

Let L be the natural logarithm of the CO

type-approval value:

the natural logarithm of the measurement for the i-th vehicle of the sample;

an estimate of the production standard deviation (after taking the natural logarithm of the measurements);

the current sample number.

9.3.2.4. Compute for the sample, the test statistic quantifying the sum of the standardised deviations to the limit and defined as:

[Bild bitte in Originalquelle ansehen]

9.3.2.5. Then:

9.3.2.5.1.

if the test statistic is greater than the pass decision number for the sample given in Table 1, a pass decision is reached;

9.3.2.5.2.

if the test statistic is less than the fail decision number for the sample size given in Table 1, a fail decision is reached;

9.3.2.5.3.

otherwise, an additional vehicle is tested according to Annex 6 and the procedure is applied to the sample with one unit more.

9.3.3. Conformity of production when manufacturer’s statistical data is unsatisfactory or unavailable.

9.3.3.1. The following sections describe the procedure to be used to verify the CO

conformity of production requirements when the manufacturer’s evidence of production standard deviation is either unsatisfactory or unavailable.

9.3.3.2. With a minimum sample size of three the sampling procedure is set so that the probability of a lot passing a test with 40 per cent of the production defective is 0,95 (producer’s risk = 5 per cent) while the probability of a lot being accepted with 65 per cent of the production defective is 0,1 (consumer’s risk = 10 per cent).

9.3.3.3. The measurement of CO

is considered to be log normally distributed and should first be transformed by taking the natural logarithms. Let m

and m denote the minimum and maximum sample sizes respectively (m

= 3 and m = 32) and let n denote the current sample number.

9.3.3.4. If the natural logarithms of the measurements in the series are x

, x

, …, x

and L is the natural logarithm of the CO

type-approval value, then define:

ANNEX 6

METHOD OF MEASURING EMISSIONS OF CARBON DIOXIDE AND FUEL CONSUMPTION OF VEHICLES POWERED BY AN INTERNAL COMBUSTION ENGINE ONLY

1. SPECIFICATION OF THE TEST

1.1. Emissions of carbon dioxide (CO

) and fuel consumption of vehicles powered by an internal combustion engine only shall be determined according to the procedure for the Type I test as defined in Annex 4 to Regulation No 83 in force at the time of the approval of the vehicle.

1.2. Emissions of carbon dioxide (CO

) and fuel consumption shall be determined separately for the Part One (urban driving) and the Part Two (extra-urban driving) of the specified driving cycle.

1.3. In addition to the conditions specified in Annex 4 to Regulation No 83 in force at the time of the approval of the vehicle, the following conditions apply:

1.3.1.

Only the equipment necessary for the operation of the vehicle during the test shall be in use. If there is a manually controlled device for the engine intake air temperature, it shall be in the position prescribed by the manufacturer for the ambient temperature at which the test is performed. In general, the auxiliary devices required for the normal operation of the vehicle shall be in use.

1.3.2.

If the radiator fan is temperature controlled, it shall be in the condition of normal operation on the vehicle. The passenger compartment heating system shall be switched off, as shall any air conditioning system, but such systems compressor shall be functioning normally.

1.3.3.

If a super-charger is fitted, it shall be in the normal operating condition for the test conditions.

1.3.4.

All the lubricants shall be those recommended by the manufacturer of the vehicle and shall be specified in the test report.

1.3.5.

The widest tyre shall be chosen. If there are more than three tyre sizes, the widest minus one shall be chosen.

1.4. Calculation of CO

2 and fuel consumption values

1.4.1.

The mass emission of CO

, expressed in g/km, shall be calculated from the measurement results using the provisions defined in Appendix 8 to Annex 4 to Regulation No 83 in force at the time of the approval of the vehicle.

1.4.1.1.

For this calculation the density of CO

shall be Q

CO2

= 1,964 g/litre.

1.4.2.

The fuel consumption values shall be calculated from the emissions of hydrocarbons, carbon monoxide, and carbon dioxide determined from the measurement results using the provisions defined in Appendix 8 to Annex 4 to Regulation No 83 in force at the time of the approval of the vehicle.

1.4.3.

The fuel consumption, expressed in litres per 100 km (in the case of petrol, LPG, ethanol (E85) and diesel) or in m

per 100 km (in the case of NG/biomethane) is calculated by means of the following formulae:

(a) for vehicles with a positive ignition engine fuelled with petrol (E5):

FC = (0,118/D) · [(0,848 · HC) + (0,429 · CO) + (0,273 · CO

)];

(b) for vehicles with a positive ignition engine fuelled with LPG:

norm

= (0,1212/0,538) · [(0,825 · HC) + (0,429 · CO) + (0,273 · CO

)]

If the composition of the fuel used for the test differs from the composition that is assumed for the calculation of the normalised consumption, on the manufacturer’s request a correction factor cf may be applied, as follows:

norm

= (0,1212/0,538) · (cf) · [(0,825 · HC) + (0,429 · CO) + (0,273 · CO

)]

The correction factor cf, which may be applied, is determined as follows

cf = 0,825 + 0,0693 · n

actual

;

where:

actual

the actual H/C ratio of the fuel used;

norm

= (0,1336/0,654) · [(0,749 · HC) + (0,429 · CO) + (0,273 · CO

)];

(d) for vehicles with a compression ignition engine fuelled with diesel (B5):

FC = (0,116/D) · [(0,861 · HC) + (0,429 · CO) + (0,273 · CO

)];

(e) for vehicles with a positive ignition engine fuelled with ethanol (E85):

FC = (0,1742/D) · [(0,574 · HC) + (0,429 · CO) + (0,273 · CO

)].

In these formulae:

the fuel consumption in litre per 100 km (in the case of petrol, LPG, diesel or biodiesel) or in m

per 100 km (in the case of natural gas);

the measured emission of hydrocarbons in g/km;

the measured emission of carbon monoxide in g/km;

the measured emission of carbon dioxide in g/km;

the density of the test fuel.

In the case of gaseous fuels this is the density at 15 °C.

6.3.1. The test results (fuel consumption C [l/100 km] and CO

of the vehicle’s battery.

The corrected values (C

[l/100 km] and M

, the energy balance of the electric energy storage device.

6.3.1.1. The electricity balance Q [Ah], measured using the procedure specified in Appendix 2 to this Annex, is used as a measure of the difference in the vehicle battery’s energy content at the end of the cycle compared to the beginning of the cycle. The electricity balance is to be determined separately for the Part One cycle and the Part Two cycle.

6.3.2. Under the conditions below, it is allowed to take the uncorrected measured values C and M as the test results:

(1) in case the manufacturer can prove that there is no relation between the energy balance and fuel consumption;

(2) in case that ΔΕ

batt

always corresponds to a battery charging;

(3) in case that ΔΕ

batt

always corresponds to a battery decharging and ΔΕ

batt

is within 1 per cent of the energy content of the consumed fuel (consumed fuel meaning the total fuel consumption over 1 cycle).

The change in battery energy content ΔΕ

The purpose of this Appendix is to define the method and required instrumentation for measuring the electricity balance of off-vehicle charging hybrid electric vehicles (OVC HEV and not off-vehicle charging hybrid electric vehicles (NOVC HEVs). Measurement of the electricity balance is necessary

(a) to determine when the minimum state of charge of the battery has been reached during the test procedure defined in paragraphs 3 and 4 of this Annex; and

(b) to correct the measured fuel consumption and CO

-emissions for the change in battery energy content occurring during the test, using the method defined in paragraphs 5 and 6 of this Annex.

OEM diagnostic testers are not to be used for the purpose of this test.

2.1.1.

The current transducer shall be fitted on one of the wires directly connected to the battery. In order to easily measure battery current using external measuring equipment, manufacturers should preferably integrate appropriate, safe and accessible connection points in the vehicle.

2.1.2.

The output of the current transducer shall be sampled with a minimum sample frequency of 5 Hz. The measured current shall be integrated over time, yielding the measured value of Q, expressed in Ampere hours (Ah).

2.1.3.

The temperature at the location of the sensor shall be measured and sampled with the same sample frequency as the current, so that this value can be used for possible compensation of the drift of current transducers and, if applicable, the voltage transducer used to convert the output of the current transducer.

2.2.

A list of the instrumentation (manufacturer, model No, serial No) used by the manufacturer for determining:

(a) when the minimum state of charge of the battery has been reached during the test procedure defined in paragraphs 3 and 4 of this Annex; and

(b) the correction factors K

fuel

and K

CO2

(as defined in paragraphs 5.3.3.2, 5.3.5.2, 6.3.3.2, and 6.3.5.2 of this Annex)

and the last calibration dates of the instruments (where applicable) should be provided to the technical service.

3. MEASUREMENT PROCEDURE

3.1.

Measurement of the battery current shall start at the same time as the test starts and shall end immediately after the vehicle has driven the complete driving cycle.

ANNEX 10

EMISSIONS TEST PROCEDURE FOR A VEHICLE EQUIPPED WITH A PERIODICALLY REGENERATING SYSTEM

1. INTRODUCTION

1.1. This Annex defines the specific provisions regarding type-approval of a vehicle equipped with a periodically regenerating system as defined in paragraph 2.19 of this Regulation.

2. SCOPE AND EXTENSION OF THE TYPE-APPROVAL

2.1. Vehicle family groups equipped with periodically regenerating system

The procedure applies to vehicles equipped with a periodically regenerating system as defined in paragraph 2.19 of this Regulation. For the purpose of this Annex vehicle family groups may be established. Accordingly, those vehicle types with regenerative systems, whose parameters described below are identical, or within the stated tolerances, shall be considered to belong to the same family with respect to measurements specific to the defined periodically regenerating systems.

2.1.1. Identical parameters are:

Engine:

(a) number of cylinders

(b) engine capacity (± 15 per cent)

(d) fuel system

(e) combustion process (2 stroke, 4 stroke, rotary).

Periodically regenerating system (i.e. catalyst, particulate trap):

(a) construction (i.e. type of enclosure, type of precious metal, type of substrate, cell density)

(b) type and working principle

(d) volume (± 10 per cent)

(e) location (temperature ± 50 °C at 120 km/h or 5 per cent difference of maximum temperature/pressure).

2.2. Vehicle types of different reference masses

The K

factor developed by the procedures in this Annex for type-approval of a vehicle type with a periodically regenerating system as defined in paragraph 2.19 of this Regulation, may be extended to other vehicles in the family group with a reference mass within the next two higher equivalent inertia classes or any lower equivalent inertia.

2.3. Instead of carrying out the test procedures defined in the following paragraph, a fixed K

value of 1,05 may be used, if the technical service sees no reason that this value could be exceeded.

3. TEST PROCEDURE

The vehicle may be equipped with a switch capable of preventing or permitting the regeneration process provided that this operation has no effect on original engine calibration. This switch shall be permitted only for the purpose of preventing regeneration during loading of the regeneration system and during the pre-conditioning cycles. However, it shall not be used during the measurement of emissions during the regeneration phase; rather the emission test shall be carried out with the unchanged Original Equipment Manufacturer’s (OEM) control unit.

3.1. Measurement of carbon dioxide emission and fuel consumption between two cycles where regenerative phases occur

3.1.1. The average of carbon dioxide emission and fuel consumption between regeneration phases and during loading of the regenerative device shall be determined from the arithmetic mean of several approximately equidistant (if more than 2) Type I operating cycles or equivalent engine test bench cycles. As an alternative, the manufacturer may provide data to show that the carbon dioxide emission and fuel consumption remain constant (± 4 per cent) between regeneration phases. In this case, the carbon dioxide emission and fuel consumption measured during the regular Type I test may be used. In any other case emissions measurement for at least two Type I operating cycles or equivalent engine test bench cycles must be completed: one immediately after regeneration (before new loading) and one as close as possible prior to a regeneration phase. All emissions measurements and calculations shall be carried out according to Annex 6. Determination of average emissions for a single regenerative system shall be according to paragraph 3.3 of this Annex and for multiple regeneration systems according to paragraph 3.4 of this Annex.

3.1.2. The loading process and K

determination shall be made during the Type I operating cycle, on a chassis dynamometer or on an engine test bench using an equivalent test cycle. These cycles may be run continuously (i.e. without the need to switch the engine off between cycles). After any number of completed cycles, the vehicle may be removed from the chassis dynamometer, and the test continued at a later time.

3.1.3. The number of cycles (D) between two cycles where regeneration phases occur, the number of cycles over which emissions measurements are made (n), and each emissions measurement (M′

sij

) shall be reported in Annex 1, items 4.1.11.2.1.10.1 to 4.1.11.2.1.10.4 or 4.1.11.2.5.4.1 to 4.1.11.2.5.4.4 as applicable.

3.2. Measurement of carbon dioxide emission and fuel consumption during regeneration

3.2.1. Preparation of the vehicle, if required, for the emissions test during a regeneration phase, may be completed using the preparation cycles in paragraph 5.3 of Annex 4 to Regulation No 83 or equivalent engine test bench cycles, depending on the loading procedure chosen in paragraph 3.1.2 above.

3.2.2. The test and vehicle conditions for the test described in Annex 6 apply before the first valid emission test is carried out.

3.2.3. Regeneration must not occur during the preparation of the vehicle. This may be ensured by one of the following methods:

3.2.3.1.

A ‘dummy’ regenerating system or partial system may be fitted for the pre-conditioning cycles.

3.2.3.2.

Any other method agreed between the manufacturer and the type-approval authority.

3.2.4. A cold-start exhaust emission test including a regeneration process shall be performed according to the Type I operating cycle, or equivalent engine test bench cycle. If the emissions tests between two cycles where regeneration phases occur are carried out on an engine test bench, the emissions test including a regeneration phase shall also be carried out on an engine test bench.

3.2.5. If the regeneration process requires more than one operating cycle, subsequent test cycle(s) shall be driven immediately, without switching the engine off, until complete regeneration has been achieved (each cycle shall be completed). The time necessary to set up a new test should be as short as possible (e.g. particular matter filter change). The engine must be switched off during this period.

3.2.6. The carbon dioxide emission and fuel consumption values during regeneration (M

) shall be calculated according to Annex 6. The number of operating cycles (d) measured for complete regeneration shall be recorded.

3.3. Calculation of the combined carbon dioxide emission and fuel consumption of a single regenerative system

The calculation of the factor (K

) for multiple periodic regenerating systems is only possible after a certain number of regeneration phases for each system. After performing the complete procedure (A to B, see Figure 10/2), the original starting conditions A should be reached again.

3.4.1. Extension of approval for a multiple periodic regeneration system

3.4.1.1.

If the technical parameter(s) and or the regeneration strategy of a multiple regeneration system for all events within this combined system are changed, the complete procedure including all regenerative devices should be performed by measurements to update the multiple K

factor.

3.4.1.2.

If a single device of the multiple regeneration system changed only in strategy parameters (i.e. such as ‘D’ and/or ‘d’ for DPF) and the manufacturer could present technical feasible data and information to the technical service that:

(a) there is no detectable interaction with the other device(s) of the system; and

(b) the important parameters (i.e. construction, working principle, volume, location etc.) are identical,

the necessary update procedure for K

could be simplified.

As agreed between the manufacturer and the technical service in such a case only a single event of sampling/storage and regeneration should be performed and the test results (‘M

’, ‘M

’) in combination with the changed parameters (‘D’ and/or ‘d’) could be introduced in the relevant formula(s) to update the multiple K

factor in a mathematical way under substitution of the existing basis K

factor formula(s).
