Abstract

Système de recirculation (100) des gaz d'échappement d'un moteur thermique comprenant une culasse (50) dont laquelle sont creusés : - des premières canalisations (53), - une canalisation d'extrémité latérale (55), toutes les canalisations étant connectées avec des chambres à combustion, - et un conduit de recirculation (56) de gaz d'échappement adjacent à la canalisation d'extrémité (55), débouchant tous par une bouche (54, 60) distincte d'une face d'échappement de culasse dans un collecteur d'échappement, chacune des canalisations étant connectée à un conduit d'entrée (21, 22) distinct du collecteur (20) débouchant ensuite dans un plénum d'admission (25) du collecteur, caractérisé en ce que le conduit de recirculation (56) et la canalisation d'extrémité (55) adjacente débouchent de la face d'échappement (52) par une même bouche (60) dans un même conduit d'entrée mixte (22) du collecteur d'échappement en amont du débouché dans le plénum (25) d'admission.System for recirculation (100) of the exhaust gases of a heat engine comprising a cylinder head (50) of which are hollowed: - first pipes (53), - a lateral end pipe (55), all the pipes being connected with combustion chambers, - and an exhaust gas recirculation duct (56) adjacent to the end pipe (55), all opening through a mouth (54, 60) separate from an exhaust face cylinder head in an exhaust manifold, each of the pipes being connected to an inlet duct (21, 22) separate from the manifold (20) then opening into an intake plenum (25) of the manifold, characterized in that the recirculation duct (56) and the adjacent end duct (55) open from the exhaust face (52) through the same mouth (60) into the same mixed inlet duct (22) of the exhaust manifold in upstream of the outlet in the intake plenum (25).
