Abstract

Procédé de gestion de l’alimentation d’un moteur (100) dans lequel : - à l’approche d’un point mort haut par un piston (200), des consignes concernant une combustion à venir sont établies,- à l’approche d’un point mort haut (PMH), une prédiction de la vitesse de rotation du moteur (N_TDC) lors du passage du point mort haut à venir est réalisée,- un premier seuil (S1) de vitesse de rotation et un deuxième seuil (S2) de vitesse de rotation sont prédéterminés,- lorsqu’une prédiction de vitesse de rotation au prochain PMH se situe entre les deux seuils (S1, S2), alors la consigne correspondant au début d’injection de carburant est modifiée de telle sorte que l’injection de carburant ne se produise qu’après un passage éventuel du PMH, et - lorsqu’une prédiction de vitesse de rotation au prochain PMH est inférieure au premier seuil (S1), la combustion suivante prévue est inhibée.
