Division 1 INTRODUCTION

To determine the CO₂ savings that can be attributed to the use of the Engine Idle Coasting Function, it is necessary to specify the following:

1. (1)

   The test vehicles;

2. (2)

   The procedure to precondition the vehicle;

3. (3)

   The procedure to perform the dynamometer road load determination;

4. (4)

   The procedure to define the modified testing conditions;

5. (5)

   The procedure to determine the CO₂ emissions of the eco-innovative vehicle under modified testing conditions;

6. (6)

   The procedure to determine the CO₂ emissions of the baseline vehicle under Type 1 hot start conditions;

7. (7)

   The calculation of the CO₂ savings;

8. (8)

   The calculation of the uncertainty of the CO₂ savings.
