Abstract

L'invention porte sur un procédé de contrôle d'un moteur à combustion interne à essence suralimenté comportant un arbre à cames d'admission et/ou un arbre à cames d'échappement comportant: - une étape de calcul d'un remplissage de consigne (c) en sélectionnant le minimum entre un remplissage de consigne avant saturation (a) et un remplissage maximal sous contrainte d’auto-inflammation d'une combustion (b), - une étape de comparaison entre le remplissage de consigne (c) et un remplissage maximal que peut réaliser le moteur à combustion interne avec des réglages initiaux d'arbres à cames d'admission et d'échappement, et - si le remplissage de consigne (c) est supérieur au remplissage maximal que peut réaliser le moteur à combustion interne avec les réglages initiaux (d), ledit procédé comporte en outre: - une étape d'activation d'un réglage optimum d'arbres à cames d'admission et d'échappement dépendant d'une altitude et/ou d'une température extérieure. Figure 10.
