Abstract

Dispositif de chauffage pour un dispositif de purification de gaz d’échappements à encombrement réduit Le dispositif (11) de chauffage comporte un élément chauffant (16), perméable aux gaz d’échappement et destiné à être traversé par le gaz d’échappement circulant dans une direction longitudinale (X), l’élément chauffant (16) comportant deux pôles électriques (18), et deux électrodes (20), chacune solidarisée à un pôle électrique (18) respectif, chaque électrode (20) présentant une forme générale allongée le long d’une direction d’allongement respective. Au moins l’une des électrodes (20) présente une direction d’allongement sensiblement parallèle à la direction longitudinale (X). Figure pour l'abrégé : Figure 3
