Abstract

L’invention concerne un procédé de commande d’un moteur (1) suralimenté par turbocompresseur, dans lequel on active des moyens de distribution variable (40) du moteur pour commander une levée partielle d’une soupape d’échappement (SE) d’un cylindre du moteur pendant une levée principale d’une soupape d’admission (SA) pour réintroduire des gaz d’échappement dans le cylindre lors d’une phase d’admission d’air, ledit procédé comprenant les étapes de :- fourniture d’une valeur de consigne de débit d’air du moteur tenant compte du régime et de la charge du moteur, ladite valeur de consigne permettant de fixer une valeur cible de taux de gaz d’échappement réintroduits ;- régulation du débit d’air admis dans le moteur, où le circuit d’admission est vanné par un volet d’admission, de façon à faire diminuer le débit d’air admis jusqu’à atteindre ladite valeur de consigne permettant d’obtenir ladite valeur cible de taux de gaz d’échappement réintroduits.
