Abstract

L'invention se rapporte à un procédé de gestion du fonctionnement d'un moteur (1) de véhicule, à allumage commandé et à injection directe, ledit moteur (1) comprenant au moins une chambre de combustion (2) dotée d'au moins une soupape d'admission (6) et d'au moins une soupape d'échappement (8) ainsi que d'au moins un injecteur (5) de carburant dans chaque chambre. La principale caractéristique d'un procédé selon l'invention est qu'au moins un cycle du moteur comprend les étapes suivantes, - Une étape de fermeture de la soupape d'échappement (8), - Une étape d'ouverture de la soupape d'admission (6) qui est postérieure à ladite étape de fermeture de la soupape d'échappement (8), ladite étape d'ouverture commençant avant que la soupape d'échappement (8) ne soit complétement fermée, engendrant une période de croisement (11) au cours de laquelle lesdites deux soupapes (6, 8) sont ouvertes, - Une étape d'injection d'une quantité principale (14) de carburant lorsque la soupape d'admission (6) est ouverte, - Une étape d'injection d'au moins une quantité secondaire (15, 16) de carburant durant la phase de fermeture de la soupape d'échappement (8), avant que celle-ci ne soit complètement fermée.The invention relates to a method for managing the operation of a vehicle engine (1), with spark ignition and direct injection, said engine (1) comprising at least one combustion chamber (2) provided with at least an inlet valve (6) and at least one exhaust valve (8) as well as at least one fuel injector (5) in each chamber. The main characteristic of a method according to the invention is that at least one engine cycle comprises the following steps, - A step of closing the exhaust valve (8), - A step of opening the exhaust valve intake (6) which is later than said closing step of the exhaust valve (8), said opening step beginning before the exhaust valve (8) is completely closed, generating a crossover period ( 11) during which said two valves (6, 8) are open, - A step of injecting a main quantity (14) of fuel when the intake valve (6) is open, - A step of injection of at least a secondary quantity (15, 16) of fuel during the closing phase of the exhaust valve (8), before the latter is completely closed.
