Abstract

Procédé de contrôle d’un circuit d’admission (1) d’un moteur à combustion interne suralimenté, comprenant une branche de renvoi (13) des gaz de blow-by à partir du carter inférieur du moteur, raccordée au circuit d’admission (1) en amont d’un compresseur de suralimentation (4), caractérisé en ce qu’on ferme un volet de vannage (9) contrôlant le débit des gaz dans le circuit d’admission (1) en amont de l’arrivée du blow-by, lorsque la différence de pression entre le carter inférieur du moteur et son carter d’admission, est insuffisante pour aspirer les gaz de blow-by vers l’admission. Figure pour l’abrégé : figure 1Method for controlling an intake circuit (1) of a supercharged internal combustion engine, comprising a branch (13) for returning the blow-by gases from the lower casing of the engine, connected to the intake circuit (1) upstream of a supercharger (4), characterized in that a valve flap (9) is closed controlling the gas flow in the intake circuit (1) upstream of the arrival of the blow-by, when the pressure difference between the engine's lower crankcase and its intake housing is insufficient to suck the blow-by gases towards the intake.
