Abstract

Le procédé de correction des paramètres d’injection de carburant est mis en œuvre en phase de fonctionnement transitoire du moteur thermique, le moteur thermique comprenant une boucle d’alimentation d’air intégrant un papillon doseur d’air et une vanne de recirculation des gaz d'échappement, et la correction étant déterminée en fonction d’un écart de débit d’air (EBA) dans la boucle d’alimentation d’air entre une consigne de débit d’air et un débit d’air effectif. Conformément à l’invention, une prise en compte de l’écart de débit d’air pour la correction est déterminée en fonction d’une position d’activation (PPD) du papillon doseur d’air et d’une position d’activation (PEGR) de la vanne de recirculation des gaz d'échappement. Fig.3The method of correcting the fuel injection parameters is implemented in the transient operating phase of the heat engine, the heat engine comprising an air supply loop integrating an air metering butterfly and a gas recirculation valve exhaust, and the correction being determined as a function of an air flow difference (EBA) in the air supply loop between an air flow setpoint and an actual air flow. According to the invention, taking into account the air flow difference for the correction is determined as a function of an activation position (PPD) of the air metering butterfly and an activation position (PEGR) of the exhaust gas recirculation valve.
