COMMISSION DIRECTIVE 93/116/EC of 17 December 1993 adapting to technical progress Council Directive 80/1268/EEC relating to the fuel consumption of motor vehicles

THE COMMISSION OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Community,

Having regard to Council Directive 70/156/EEC of 6 February 1970 relating to the type-approval of motor vehicles and their trailers (1), as last amended by Commission Directive 93/81/EEC (2), and in particular Article 13 (2) thereof,

Having regard to Council Directive 80/1268/EEC of 16 December 1980 on the approximation of the laws of the Member States relating to the fuel consumption of motor vehicles (3), as amended by Directive 89/491/EEC (4), and in particular Article 3 thereof,

Whereas Directive 80/1268/EEC is one of the separate directives of the EC type-approval procedure which has been established by Directive 70/156/EEC; whereas, consequently, the provisions laid down in Directive 70/156/EEC relating to vehicle systems, components and separate technical units apply to this Directive;

Whereas, in particular, Articles 3 (4) and 4 (3) of Directive 70/156/EEC require each separate Directive to have attached to it an information document incorporating the relevant items of Annex I to that Directive and also a type-approval certificate based on Annex VI thereto in order that type-approval may be computerized;

Whereas reference should be made to Council Directive 70/220/EEC (5), as last amended by Directive 93/59/EEC (6), relating to measures to be taken against air pollution by emissions from motor vehicles, because that Directive establishes technical and administrative provisions which apply also to this Directive;

Whereas, in view of the increasing concern about the environmental effects of carbon dioxide emissions, the fifth programme of action of the European Communities on the protection of the environment approved by the Council on 16 December 1992 provides for a stabilization target of these emissions; whereas it is necessary to determine the carbon dioxide emissions of light motor vehicles in the framework of the EC type-approval; whereas it is appropriate to base the measurement of carbon dioxide on the test procedure established by Directive 70/220/EEC for the measurement of the air-polluting substances of motor vehicles, and consequently to calculate fuel consumption on the basis of the results of these measurements;

Whereas the measures provided for in this Directive are in accordance with the opinion of the Committee for Adaptation to Technical Progress established by Directive 70/156/EEC,

HAS ADOPTED THIS DIRECTIVE:

6.3.3. When using the alternative method for the setting of the dynamometer, the brake is adjusted in accordance with the values of Pa listed in the above table.

6.4. Calculation of emissions

6.4.1. General provisions

6.4.1.1. Emissions of gaseous pollutants are calculated by means of the following equation:

where:

Mi = mass emission of the pollutant i in grams per kilometre;

Vmix = volume of the diluted exhaust gas expressed in litres per test and corrected to standard conditions (273,2 K and 101,33 kPa);

Qi = density of the pollutant i in grams per litre at normal temperature and pressure (273,2 K and 101,33 kPa);

Ci = concentration of the pollutant i in the diluted exhaust gas expressed in ppm and corrected by the amount of the pollutant i contained in the dilution air. If Ci is expressed in % volume, 10 6 factor is replaced by 10 2;

d = driven distance during the operating cycle in km.

6.4.1.2. Volume determination

6.4.1.2.1. Calculation of the volume when a variable dilution device with constant flow control by orifice or venturi is used. Record continuously the parameters showing the volumetric flow, and calculate the total volume for the duration of the test.

6.4.1.2.2. Calculation of volume when a positive displacement pump is used. The volume of diluted exhaust gas in systems comprising a positive displacement pump is calculated with the following formula:

V = Vo · N

where:

V = volume of the diluted exhaust gas expressed in litres per test (prior to correction);

Vo = volume of gas delivered by the positive displacement pump on testing conditions in litres per revolution;

N = number of revolutions per test.

6.4.1.2.3. Correction of the diluted exhaust-gas volume to standard conditions. The diluted exhaust-gas volume is corrected by means of the following formula:

CO2 mass emissions (see formula 1)

6.4.2. Special provisions relating to vehicles equipped with compression ignition engines

HC measurements for compression-ignition engines

The average HC concentration used in determining the HC mass emissions from compression-ignition engines is calculated with the aid of the following formula:

where:

= integral of the recording of the heated FID over the test duration (t2 t1);

Ce = HC concentration of the diluted exhaust sample as calculated from the integrated HC trace, in ppm carbon equivalent.

6.5. Interpretation of the results

6.5.1. The CO2 value 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 %. The measured value can be lower without any limitations.

6.5.2. If the measured value of CO2 exceeds the manufacturer's declared CO2 value by more than 4 %, 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 %, then the value declared by the manufacturer is taken as the type-approval value.

6.5.3. If the average still exceeds the declared value by more than 4 %, a final test is run on the same vehicle.

The average of the three test results is taken as the type-approval value.

7. CALCULATION OF FUEL CONSUMPTIONS

7.1. The fuel consumptions are calculated from the emissions of hydrocarbons, carbon monoxide and carbon dioxide calculated in accordance with paragraph 6.

7.2. The fuel consumptions expressed in litres per 100 km are calculated using the following formulae:

(a) for petrol-engined vehicles:

(b) for diesel-engined vehicles:

where:

FC = fuel consumption in litres per 100 km;

HC = measured emission of hydrocarbon in g/km;

CO = measured emission of carbon monoxide in g/km;

CO2 = measured emission of carbon dioxide in g/km;

D = density of the test fuel.

8. AMENDMENTS TO APPROVALS

8.1. In the case of amendments to approvals granted pursuant to this Directive the provisions of Article 5 of Directive 70/156/EEC shall apply.

9. CONFORMITY OF PRODUCTION FOR CO2 EMISSIONS

9.1. As a general rule, measures to ensure the conformity of production with regard to CO2 emissions from vehicles is checked on the basis of the description in the type-approval certificate set out in Annex II to this Directive and in accordance with the provisions of Article 10 of Directive 70/156/EEC.

If the authority is not satisfied with the auditing procedure of the manufacturer, then points 2.4.2 and 2.4.3 of Annex X to Directive 70/156/EEC shall apply.

9.1.1. If a vehicle type has had one or several extensions, the tests will be carried out on the vehicle(s) described in the information package which accompanied the first type-approval application.

9.1.1.1. Conformity of the vehicle for the CO2 test.

9.1.1.1.1. Three vehicles are randomly taken in the series and are tested as described in paragraph 6 of this Annex.

9.1.1.1.2. If the authority is satisfied with the production standard deviation given by the manufacturer, according to Annex X to Directive 70/156/EEC, the tests are carried out according to point 9.2 of this Annex.

If the authority is not satisfied with the production standard deviation given by the manufacturer according to Annex X to Directive 70/156/EEC, the tests are carried out according to point 9.3 of this Annex.

9.1.1.1.3. 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 CO2, according to the test criteria applied in the appropriate table.

If no pass decision and/or no fail decision is reached for CO2, a test is carried out on an additional vehicle (see Figure I/8).

FIGURE I/8 9.1.1.2. Notwithstanding the requirements of point 5.1.1 of this Annex, the tests will be carried out on vehicles which have not travelled any distance.

9.1.1.2.1. 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.

9.1.1.2.2. If the manufacturer asks to conduct a running-in procedure ('x' km, where x & le; 15 000 km), it may be carried out as follows:

- the emission of CO2 will be measured at zero and at 'x' km on the first tested vehicle (which can be the type-approval vehicle),

- the evolution coefficient of the emission between zero and 'x' km will be calculated as follows:

It may be less than one,

- 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.

9.1.1.2.3. As an alternative to this procedure, the car manufacturer can use a fixed evolution coefficient EC of 0,92 and multiply all values of CO2 measured at zero km by this factor.

9.1.1.2.4. The reference fuels described in Annex VII to Directive 91/441/EEC shall be used for this test.

9.2. Conformity of production when manufacturer's statistical data is available

9.2.1. The following sections describe the procedure to be used to verify the CO2 conformity of production requirements when the manufacturer's production standard deviation is satisfactory.

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

9.2.3. The following procedure is used (see Figure I/8).

Let L be the natural logarithm of the CO2 type-approval value:

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

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

n = the current sample number.

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

S9.2.5. Then:

- if the test statistic is greater than the pass decision number for the sample size given in Table I/ /9.2.5, a pass decision is reached,

- if the test statistic is less than the fail decision number for the sample size given in Table I/ /9.2.5, a fail decision is reached,

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

9.3. Conformity of production when manufacturer's statistical data is unsatisfactory or unavailable.

9.3.1. The following sections describe the procedure to be used to verify the CO2 conformity of production requirements when the manufacturer's evidence of production standard deviation is either unsatisfactory or unavailable.

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

9.3.3. The measurement of CO2 is considered to be log normally distributed and should first be transformed by taking the natural logarithms. Let m0 and m denote the minimum and maximum sample sizes respectively (m0 = 3 and m = 32) and let n denote the current sample number.

9.3.4. If the natural logarithms of the measurements in the series are x1, x2, . . ., xj and L is the natural logarithm of the CO2 type-approval value, then define:

SS9.3.5. Table I/ /9.3.5 shows values of the pass (An) and fail (Bn) decision numbers against current sample number. The test statistic is the ratio dn / Vn and shall be used to determine whether the series has passed or failed as follows:

for m0 & le; n & le; m:

- pass the series if dn / Vn & le; An,

- fail the series if dn / Vn & ge; Bn,

- take another measurement if An < dn / Vn < Bn.

9.3.6. Remarks
