Abstract

Ce procédé de contrôle de la richesse d’un mélange carburé pour moteur (10) à combustion interne d’une automobile équipé d’un système de calage variable (50) des soupapes du moteur, comprend des étapes de : détection d’un changement du point de fonctionnement du moteur;calcul d’au moins une consigne de position dudit système;mesure d’une position courante dudit système;calcul prédictif d’une position dudit système; estimation du débit d’air à partir dudit calcul prédictif;calcul à partir de l’estimation du débit d’air, de la quantité de carburant à injecter pour un fonctionnement du moteur à richesse 1, et ouverture d’injecteurs de carburant du moteur pour injecter ladite quantité de carburant. Le calcul prédictif de la position du système de calage variable des soupapes (50) correspond à la position dudit système à l’instant de l’ouverture des injecteurs de carburant.
