Abstract

L'invention porte principalement sur un moteur à combustion interne comportant: - une culasse (41), - une conduite de redirection (40) de gaz d'échappement apte à rediriger une partie des gaz d'échappement issus d'un collecteur d'échappement (20) vers une admission (51) dudit moteur à combustion interne, caractérisé en ce que ladite conduite de redirection (40) est intégrée à ladite culasse (41) et connectée audit collecteur d'échappement (20) via un piquage (43) réalisé dans une paroi dudit collecteur d'échappement (20).The invention relates mainly to an internal combustion engine comprising: - a cylinder head (41), - an exhaust gas redirection pipe (40) capable of redirecting a portion of the exhaust gas coming from an exhaust manifold. exhaust (20) to an intake (51) of said internal combustion engine, characterized in that said redirection line (40) is integrated with said cylinder head (41) and connected to said exhaust manifold (20) via a nozzle (43 ) made in a wall of said exhaust manifold (20).
