PROCEDE DE COMMANDE D'UN MOTEUR THERMIQUE

摘要

The method involves determining a reference cylinder richness to be applied to a total number of cylinders (3) of a multi-cylinder thermal engine (1) to meet a required exhaust richness (psiech). A number of effective cylinders taking part in a combustion process is determined. A corrected richness applied to the cylinders taking part in the combustion process is determined from the reference richness and the number of effective cylinders when the number of effective cylinders is lesser than the total number of cylinders, where the corrected richness complies with the exhaust richness. An independent claim is also included for a car.
