Abstract

L'invention concerne un procédé pour l'alimentation en gaz d'un moteur thermique (2) que comporte un véhicule et qui est raccordé à une ligne d'échappement (1) comportant au moins un élément d'échappement (3) dont un élément de dépollution (5, 5'), caractérisé par le fait qu'il consiste en ce que l'on collecte une partie au moins des gaz d'échappement au niveau et/ou en aval de l'élément de dépollution (5, 5') et en ce que l'on alimente le moteur (2) avec ces gaz d'échappement collectés et dépollués. Cette invention concerne, également, un élément d'échappement (3) comportant des moyens (9) pour alimenter un moteur (2) avec des gaz d'échappement définis par un moyen (10) pour collecter des gaz d'échappement au niveau d'un élément de dépollution (5, 5') ainsi que par un moyen (11) d'acheminement des gaz collectés vers le moteur (2). L'invention a, encore, trait à une ligne d'échappement (1) et à un véhicule à moteur thermique (2) comportant des moyens (9) pour alimenter le moteur (2) avec des gaz d'échappement.
