Abstract

La présente invention a pour objet un procédé de correction d'une durée d'injection de carburant injecté par au moins un injecteur dans une chambre de combustion d'un cylindre de moteur thermique de véhicule automobile. Le procédé comprend une phase standard, une phase d'arrêt et une phase de reprise pendant laquelle la durée d'injection des injecteurs est corrigée à partir de la dernière valeur ICVA calculée pendant la phase de reprise et de la dernière valeur MFMA calculée pendant la phase standard.
