After a survey among 39 European laboratories, data were obtained concerning 1 556 vehicles and 29 825 measurements (1 measurement corresponds to 1 vehicle, 1 cycle and 1 pollutant). Data were measured during standardised and representative cycles. The data received were analysed in order to model cold-start-related excess omissions (defined as the difference between cold and hot omissions, for a same cycle) for 4 regulated pollutants (co, c02, hc, nox), fuel consumption and 121 non regulated pollutants as a function of various parameters: technology or omission standard, average speed, ambient travelled distance. Mots clés libres : transport; émission; pollutant; cold start; driving cycle; catalyst; diesel; passenger car; ambient température; engine temperature; model; speed; travelled distance
