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 suivantes : - générer une valeur de consigne de débit d'air du moteur tenant compte du régime et de la charge du moteur, ladite valeur de consigne de débit d'air étant apte à fixer une valeur cible de taux de gaz d'échappement réintroduits ; - réguler le débit d'air admis (Qair) dans le moteur en agissant sur le turbocompresseur par rapport à ladite valeur de consigne de débit d'air, de façon à faire diminuer le débit d'air admis jusqu'à atteindre ladite valeur de consigne de débit d'air.The invention relates to a method for controlling an engine (1) supercharged by a turbocharger, in which variable valve means (40) of the engine are activated in order to control a partial lift of an exhaust valve (SE) of the engine. a cylinder of the engine during a main lift of an intake valve (SA) for reintroducing exhaust gases into the cylinder during an air intake phase, said method comprising the following steps: - generating a engine air flow setpoint value taking into account the engine speed and load, said air flow setpoint value being able to set a target value of the rate of reintroduced exhaust gases; - regulate the flow of air admitted (Qair) into the engine by acting on the turbocharger with respect to said air flow setpoint value, so as to reduce the intake air flow until said value of air flow setpoint.
