Résumé / Abstract
After an inquiry to 39 European laboratories, 15 500 measurements (1 measurement corresponds to 1 vehicle, 1 normalized or representative cycle and 1 pollutant) concerning 661 vehicles were analysed in order to modellize the pollutant overemission (c02, co, hc, nox) during cold start and fuel overconsumption. Using these data, we propose an equation describing the relation between overemission and the following parameters: technology (diesel, catalyst and conventional cars), average speed, ambient temperature and travelled distance. The obtained data were measured for passenger cars and an extension to duty vehicles proposed. The model is a part of an emission inventory model.
