Patent

CA 2374749

A particulate filter (22) for removing particulates included in an exhaust gas discharged from a combustion chamber (5) is arranged in an engine exhaust passage. The particulate filter has wall partitions (54) which the exhaust gas can pass through. The particulates included in the exhaust gas are removed by oxidation in the interior of the partitions. The particulates are fluidized in the interior of the partitions.

L'invention concerne un dispositif d'épuration de gaz d'échappement comprenant un filtre à particules (22) installé dans un passage de gaz d'échappement de moteur, conçu pour supprimer les particules contenues dans les gaz d'échappement dégagés par une chambre de combustion (5). Ledit filtre à particules est doté d'une paroi de séparation (54) perméable aux gaz d'échappement, les particules contenues dans les gaz d'échappement pouvant être ainsi supprimées par oxydation dans la paroi de séparation, les particules étant forcée à s'écouler ainsi dans ladite paroi.
