Abstract

La ligne d'échappement comprend : un conduit (3) comportant un tronçon d'injection (7) comprenant un canal interne délimité par une paroi latérale, le flux de gaz d'échappement comportant des veines centrales de gaz d'échappement dans une zone centrale du canal interne (17) et des veines périphériques de gaz d'échappement à proximité de la paroi latérale; un injecteur (5) de réactif, apte à injecter un réactif suivant une direction d'injection (F1). Le conduit (3) est conformé de manière à ce que les veines centrales de gaz d'échappement circulent sensiblement parallèlement à la ligne centrale (L1) du canal interne, la ligne d'échappement (1) comprenant des moyens (31) pour conférer à au moins certaines veines périphériques un mouvement à travers le canal interne tournant autour d'un axe de rotation faiblement incliné par rapport à la direction d'injection (F1).
