TECHNICAL EVALUATION OF THE EXHAUST EMISSION FROM DIFFERENT ENGINE FAMILIES

This report focuses on 56 light duty vehicles. They have been tested according to the urban (UDC) and the highway (HDC) driving cycles of the A13-Regulation. Of these 56 vehicles, 30 have been tested according to the test procedure of the EEC-directive 91/441 and among these vehicles, 21 have been tested according to a proposed modified test procedure of the same EEC-directive (OICA C). This is the final report of project MTC 9302. Of the eleven vehicle groups tested, only four are within the stipulated emission standards regarding average values for all regulated exhaust emissions. For seven respectively six of the vehicle groups, the average CO- and HC-emissions are above standards according to the urban driving cycle (UDC) of the A13-Regulation. Only two vehicles exceed the highway driving cycle (HDC) nitric oxide emission standard. Of the ten vehicles tested regarding evaporative emissions five failed. The average HC-emission of the SHED-tests is above the emission standard. Ten vehicles have been tested at different constant speeds and the results from this are presented. In general the emissions of the regulated components and the fuel consumption increase with speed although the selection of gear also has a large influence. (A)
