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.The invention relates to a method for controlling the combustion of a diesel engine capable of operating at least according to a first operating mode with stratified load over the entire engine field, and according to a second operating mode with partially pre-mixed load that it can adopt if the speed-load operating point of the motor field lies within a limited subset of points of the field. According to the invention, the adoption of the second mode is not authorized if the setpoint tracking deviation of at least one adjustment loop of a parameter representative of the quantity of air or the quantity of gas d exhaust recirculated to intake is too high. In addition, the switchover from the second mode to the first mode is caused if said setpoint tracking deviation of at least one of the two adjustment loops is too high, and/or if a parameter representative of the stability of the combustion is too high. scattered.
