Abstract

Le procédé de purification comprend les étapes suivantes : - se procurer un dispositif de purification (4) comportant au moins un organe de purification (5) des gaz d'échappement ayant une face amont (9) par laquelle les gaz d'échappement pénètrent dans l'organe de purification (5) et une face aval (10) par laquelle les gaz d'échappement sortent de l'organe de purification (5); - en l'absence de circulation des gaz d'échappement forcée par un moteur (3) du véhicule à travers l'organe de purification (5), chauffage d'au moins l'une de la zone amont (7) et de la zone aval (8) de manière radiative, par exemple avant le démarrage du moteur (3) du véhicule.
