Abstract

Moteur (10) à allumage commandé comprenant un circuit de recirculation (24) des gaz d’échappement à l’admission comprenant une vanne « V EGR HP » (26) configurée pour réguler le débit des gaz d’échappement à haute pression recyclés à l’admission du moteur, et au moins deux soupapes d’admission (1, 2) par cylindre (12) reliées à un collecteur d’admission (14) respectivement par un premier et un deuxième conduit d’admission (31), les deuxièmes soupapes d’admission (2) étant couplées à un dispositif (40) de régulation du flux d’air. Le moteur comprend un système (50) de commande de la répartition en air frais et en gaz d’échappement recirculés dans les premiers conduits d’admission (31, 32) de chaque cylindre (12) configuré pour commander l’ouverture et la fermeture de la vanne (26) et le dispositif (40) de régulation du flux d’air via les deuxièmes soupapes (2) selon trois modes de fonctionnement du moteur (10). Figure pour l’abrégé : Fig 1Spark-ignition engine (10) comprising an inlet exhaust gas recirculation circuit (24) comprising a "V EGR HP" valve (26) configured to regulate the flow of high pressure exhaust gas recirculated to the intake of the engine, and at least two intake valves (1, 2) per cylinder (12) connected to an intake manifold (14) respectively by a first and a second intake duct (31), the second intake valves (2) being coupled to a device (40) for regulating the air flow. The engine comprises a system (50) for controlling the distribution of fresh air and recirculated exhaust gas in the first intake ducts (31, 32) of each cylinder (12) configured to control the opening and closing of the valve (26) and the device (40) for regulating the air flow via the second valves (2) according to three operating modes of the engine (10).
