Abstract

L'invention concerne un dispositif d'injection d'air dans une ligne d'échappement comportant un conduit (3) d'échappement des résidus (5) de la combustion de carburant dans un moteur à combustion interne (1), ledit dispositif comportant des moyens d'amenée d'air dans ledit conduit. Le dispositif selon l'invention est remarquable en ce qu'il comporte en combinaison des moyens (10) pour répartir l'air amené autour d'une zone (8) interne au conduit (3) traversée par les résidus de combustion et des moyens (11) pour injecter l'air, après répartition, dans la zone (8), à travers au moins deux ouvertures (11) espacées suivant la longueur du conduit.
