Abstract

Dispositif de purification de gaz d’échappement à double boîtier Le dispositif (10) de purification comporte un boîtier extérieur de logement (12), s’étendant le long d’un axe longitudinal (X), et dans lequel le gaz d’échappement est destiné à circuler, un bloc de purification (14), logé dans le boîtier extérieur de logement (12), intégrant au moins un élément inductif (18), et un boîtier intérieur d’induction (21), logé dans le boîtier extérieur de logement (12) et entourant le bloc de purification (14), et comprenant un dispositif d’induction (22), configuré pour induire un courant électrique dans l’au moins un élément inductif (18). Il comporte un ensemble (32) de maintien et d’isolation, logé dans le boîtier extérieur de logement (12), et entourant le bloc de purification (14), l’ensemble (32) de maintien et d’isolation comportant au moins l’un des éléments suivants : - une nappe de maintien intérieure (36), disposée radialement entre le boîtier intérieur d’induction (21) et le bloc de purification (14), et/ou - des anneaux d’extrémité (38a, 38b), entourant le bloc de purification (14), et disposés de part et d’autre du boîtier intérieur d’induction (21) dans une direction longitudinale parallèle à l’axe longitudinal (X).
