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).
