Abstract

Des problèmes sont fréquemment rencontrés pour recycler des quantités de gaz d'échappement suffisantes dans des moteurs suralimentés à grand volume par l'intermédiaire d'un échangeur de chaleur des gaz d'échappement (5) et d'une soupape de recyclage des gaz d'échappement (14). L'objet de l'invention est d'éviter ces problèmes. A cet effet, deux canaux d'évacuation des gaz d'échappement (20, 22) sont disposés dans le module de refroidissement des gaz d'échappement et s'étendent, en étant séparés l'un de l'autre, de l'entrée (26) du carter de soupape de recyclage des gaz d'échappement (2) au carter de clapet de refoulement des gaz d'échappement (10) en passant par l'échangeur de chaleur des gaz d'échappement (5). Des clapets de refoulement des gaz d'échappement (68, 70, 72, 74) empêchant un reflux des gaz d'échappement sont disposés dans le module de refroidissement derrière ces canaux d'évacuation des gaz d'échappement (20, 22) séparés, de sorte que les pulsations de pression présentes peuvent être utilisées pour garantir une quantité de recyclage des gaz d'échappement suffisante.
