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.The present invention relates to a method for correcting a duration of injection of fuel injected by at least one injector into a combustion chamber of a cylinder of a heat engine of a motor vehicle. The method comprises a standard phase, a stop phase and a recovery phase during which the injection duration of the injectors is corrected from the last ICVA value calculated during the recovery phase and from the last MFMA value calculated during the recovery phase. standard phase.
