Abstract

La présente invention concerne un dispositif et un procédé de contrôle de l'admission d'un cylindre (1) d'un moteur à combustion interne. Le cylindre (1) est relié à deux entrées de gaz, une première entrée de gaz (4) à une première pression P1, et une deuxième entrée de gaz (5) à une deuxième pression P2 supérieure à la première pression P1. Le dispositif et procédé contrôlent l'admission de gaz dans le cylindre par admission d'abord du gaz issu de la première entrée de gaz (4), puis par admission du gaz issu de la deuxième entrée de gaz (5). En outre, le dispositif et le procédé contrôlent le passage de gaz issu de la deuxième entrée de gaz (5) vers le conduit d'échappement (9).The present invention relates to a device and a method for controlling the intake of a cylinder (1) of an internal combustion engine. The cylinder (1) is connected to two gas inlets, a first gas inlet (4) at a first pressure P1, and a second gas inlet (5) at a second pressure P2 greater than the first pressure P1. The device and method control the admission of gas into the cylinder by first admitting gas from the first gas inlet (4), then by admitting gas from the second gas inlet (5). In addition, the device and the method control the passage of gas from the second gas inlet (5) to the exhaust duct (9).
