Abstract
Procédé de réglage de la recirculation partielle des gaz d’échappement à l’admission d’un moteur diesel . L’invention concerne un procédé de réglage de la recirculation partielle des gaz d’échappement à l’admission d’un moteur diesel suralimenté comprenant un circuit EGR à haute pression et un circuit EGR à basse pression. Le taux d’EGR et la répartition entre débit de gaz EGR à haute pression et débit de gaz EGR à basse pression est définie à priori pour respecter un niveau d’émissions de NOx à la sortie du moteur. Selon l’invention, on modifie pas à pas la répartition entre les débits de gaz EGR à haute et à basse pression de manière à diminuer le débit d’oxydes d’azote à la sortie du circuit d’échappement du moteur.
