Abstract: The emission coefficient is defined as a factor which, when multiplied by the quantity of polluting products discharged by the new engine, allows the estimation with a satisfactory degree of precision of the pollutant quantity (CO, HC, NOx) sent off by the engine after a certain number of years and a certain mileage covered. The emission deterioration factor was determined by disposing of a rich database on the polluting emissions of certain cars grouped according to their cylinder capacity and the treatment degree of the combustion gas, in accordance with the European norms (Euro I….Euro VI).
