Abstract

L'invention concerne une combinaison (10) de convertisseur catalytique et de résonateur contenue dans une cartouche (12) commune. Le composant convertisseur catalytique (24) est disposé en amont du composant résonateur (34) (par rapport au débit des gaz d'échappement du moteur) pour recevoir une chaleur supplémentaire provenant des gaz d'échappement pénétrant dans le dispositif. De préférence, l'élément substrat (28) du composant convertisseur catalytique (24) est formé dans une matière en céramique dure et résistante à la chaleur telle que Dow-Corning XT ou une autre matière appropriée en céramique. L'utilisation de cette matière dure et résistante à la chaleur permet d'avoir des parois de substrat relativement minces, ce qui permet d'obtenir un rapport élevé entre la zone de surface et le volume du substrat. Les passages entre les parois du substrat sont relativement larges également, ce qui réduit la résistance intérieure contre une augmentation du débit dans ces passages.
