Abstract

Dans des véhicules à moteur, par exemple, les gaz d'échappement doivent traverser un réacteur au plasma qui fonctionne selon le principe de la décharge à inhibition diélectrique ("décharge silencieuse"). Le réacteur au plasma comprend au moins deux électrodes et au moins un corps diélectrique. Les réacteurs au plasma connus contiennent plusieurs sections de décharge adjacentes. Selon l'invention, plusieurs sections de décharge concentriques (2-9) se suivent dans le sens d'écoulement, deux systèmes de tuyaux (10, 20) étant coaxialement emboîtés l'un dans l'autre à cet effet. Au moins un des systèmes de tuyaux (10, 20), de préférence le deuxième système de tuyaux (20), est enduit d'un matériau diélectrique sur ses côtés exposés aux gaz d'échappement.
