Abstract

L'invention concerne un circuit de recirculation partielle des gaz d'échappement (1) à l'admission pour un moteur à combustion interne comprenant au moins deux cylindres (12, 13), dont au moins un premier cylindre (13) est dédié à la production de gaz d'échappement à recirculer, ledit circuit de recirculation des gaz d'échappement (1) comprenant :une première extrémité configurée pour être connectée à l'échappement du premier cylindre (13) du moteur ; au moins une seconde extrémité configurée pour être connectée à l'admission des au moins deux cylindres (12, 13) du moteur ; et une chambre formant un volume tampon agencée entre la première extrémité et la au moins une deuxième extrémité du circuit de recirculation des gaz d'échappement (1). L'invention concerne également un moteur et un véhicule automobile comprenant un tel circuit de recirculation des gaz d'échappement (1).The invention relates to a circuit for partial recirculation of the exhaust gases (1) at the intake for an internal combustion engine comprising at least two cylinders (12, 13), of which at least a first cylinder (13) is dedicated to producing exhaust gas to be recirculated, said exhaust gas recirculation circuit (1) comprising: a first end configured to be connected to the exhaust of the first cylinder (13) of the engine; at least one second end configured to be connected to the inlet of the at least two cylinders (12, 13) of the engine; and a chamber forming a buffer volume arranged between the first end and the at least one second end of the exhaust gas recirculation circuit (1). The invention also relates to an engine and a motor vehicle comprising such an exhaust gas recirculation circuit (1).
