Abstract

L'invention concerne un procédé de contrôle de la combustion d'un moteur diesel apte à fonctionner au moins selon un premier mode de fonctionnement à charge stratifiée sur la totalité du champ moteur, et selon un deuxième mode de fonctionnement à charge partiellement pré-mélangée qu'il peut adopter si le point de fonctionnement régime-charge du champ moteur se trouve dans un sous-ensemble limité de points du champ. Selon l'invention, l'adoption du deuxième mode n'est pas autorisée si l'écart de suivi de consigne d'au moins une boucle de réglage d'un paramètre représentatif de la quantité d'air ou de la quantité de gaz d'échappement recyclés à l'admission est trop élevé. En outre, le basculement du deuxième mode vers le premier mode est provoqué si ledit écart de suivi de consigne d'au moins une des deux boucles de réglage est trop élevé, et/ou si un paramètre représentatif de la stabilité de la combustion est trop dispersé.
