affixed to a vehicle shows that the vehicle type concerned has been approved in the Netherlands (E4) pursuant to Regulations Nos. 101 and 83*.  The first two digits of the approval numbers indicate that, at the dates when the respective approvals were given, Regulation No. 101 with the 01 series of amendments incorporated and Regulation No. 83 already included the 05 series of amendments.

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 (CO2) 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 4a of Regulation No. 83 in force at the time of the approval of the vehicle.

     1.2. Emissions of carbon dioxide (CO2) 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 4a of 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 tyres shall be chosen.  If there are more than three tyre sizes, the widest minus one shall be chosen.

     1.4. Calculation of CO2 and fuel consumption values

     1.4.1. The mass emission of CO2, expressed in g/km, shall be calculated from the measurement results using the provisions defined in paragraph 6.6. of Annex 4a of Regulation No. 83 in force at the time of the approval of the vehicle.

     1.4.1.1. For this calculation the density of CO2 shall be QCO2 = 1.964 g/litre.

     1.4.2. The fuel consumption values
