Abstract

Le système d'échappement pour un moteur à combustion interne avec recirculation des gaz d'échappement, comporte une unité (1) de traitement des gaz d'échappement, située sur la ligne d'échappement et comprenant un cône de sortie (12) agencé pour y relier une partie aval de la ligne d'échappement, et un dispositif de recirculation des gaz d'échappement (2), agencé pour recirculer une partie des gaz traversant l'unité de traitement. Le dispositif de recirculation (2) est relié directement et rigidement sur le cône de sortie (12), sans tubulure intermédiaire, par une partie (23) intégrante du cône de sortie.
