Abstract

Dispositif de purification de gaz d'échappement assisté par du plasma et consommant moins de courant électrique, tout en évacuant aucun gaz nocif dans l'atmosphère. Ce dispositif est constitué par un corps filtrant (7) en matériau poreux servant à recueillir des particules dans le gaz d'échappement (2) simultanément au passage du gaz à travers ce matériau. Filtre de particules (11) du type récupération de plasma construit par montage d'une électrode-barre (9) et d'une électrode tubulaire (10) dans le corps filtrant (7), de manière à produire du plasma dans ce dernier. Le filtre de particules (11) loge dans un boîtier (12) au milieu d'un tuyau d'échappement (3) et des catalyseurs d'oxydation (16, 17) sont placés à proximité du filtre (11) et à travers celui-ci, de sorte que ce filtre (11) peut exercer un effet de rétention de chaleur.
