Abstract

Dispositif de chauffage de gaz d’échappement, comportant une tige d’alimentation électrique perfectionnée Le dispositif de chauffage comporte un élément électrique chauffant conformé pour être agencé dans un flux de gaz d’échappement, et une tige d’alimentation électrique (17) connectée à l’élément électrique chauffant. La tige d’alimentation électrique (17) comporte : - une âme (20) réalisée en un premier matériau conducteur présentant une conductivité électrique supérieure à 5,0x106S.m-1, et - une gaine rigide (24) réalisée en un second matériau conducteur résistant à l’oxydation due aux gaz d’échappement.
