Abstract

Dispositif de purification de gaz d’échappement, ligne d’échappement et véhicule associé Ce dispositif (14) de purification de gaz d’échappement comprend un conduit (16) définissant un passage (32) de circulation de gaz d’échappement configuré pour conduire les gaz d’échappement selon un axe central (D-D’) du passage (32) dans un sens de circulation depuis une extrémité amont (28) du dispositif (14) vers une extrémité aval (30) du dispositif (14), ledit dispositif (14) comprenant : - une bobine (20) configurée pour générer un champ électromagnétique ; et - un substrat (18) de purification des gaz d’échappement s’étendant dans le passage (32), le substrat de purification (18) comprenant un matériau ferromagnétique et étant adapté pour être chauffé par induction du champ électromagnétique généré par la bobine (20). Le substrat de purification (18) comporte une cavité centrale (34) s’étendant selon l’axe central (D-D’) du passage (32), la bobine (20) étant disposée dans la cavité centrale (34).
