Division 1 INTRODUCTION

In order to determine the CO₂ reduction that can be attributed to the use of the enthalpy storage tank technology (EST system), it is necessary to establish the following:

1. (a)

   the testing procedure to be followed for determining the cool-down curves of the baseline vehicle (the vehicle fitted with a deactivated enthalpy storage tank) and the eco-innovation vehicle;

2. (b)

   the testing procedure to be followed for determining the CO₂ emission at different engine coolant start temperature;

3. (c)

   the testing procedure to be followed for determining the theoretical temperature of the engine after discharging the EST system;

4. (d)

   the testing procedure to be followed for determining the Hot start benefit;

5. (e)

   the formulae to be used for determining the CO₂ savings;

6. (f)

   the formulae to be used for determining the statistical error and significance of the results.
