Abstract:Within the framework of the European Artemis project, the emissions of unregulated compounds were measured on new technology passenger cars. A sample of passenger cars was tested on a chassis dynamometer with constant volume sampling (CVS). The measurement of unregulated compounds comprised about 100 different VOC in the C 2 -C 6 and C 7 -C 15 range and carbonyl compounds. The sampling of these compounds was made using sorbent tubes followed by analysis with chromatography technology in liquid and gas phases.The influence of cold and warm starting conditions on the VOC composition was determined.The emission factors were determined and compared for either gasoline or diesel vehicles.The influence of the technology was evaluated and a first approach to understand the effect of recent technology on the ozone formation was developed.
