CA 2415296

A particulate filter (22) is arranged in an exhaust passage of an internal combustion engine. Whether the particulate deposited on the particulate filter (22) has changed in property to a property harder to oxidize compared with right after deposition is predicted or judged. When the fact that the particulate deposited on the particulate filter (22) has changed in property to a property harder to oxidize compared with right after deposition is predicted or judged, the air-fuel ratio of the exhaust gas flowing into the particulate filter (22) is switched temporarily from lean to rich.

L'invention concerne un filtre à particules (22) disposé dans un passage d'échappement dans un moteur à combustion interne. On prévoit ou estime si la propriété des fines particules déposées sur le filtre à particules (22) a changé ou non en une propriété moins susceptible d'être oxydée que celle suivant directement le dépôt. Si on prévoit ou estime que la propriété a changé en une propriété moins susceptible d'être oxydée, le rapport air/carburant d'un gaz d'échappement s'écoulant dans le filtre à particules (22) est temporairement modifié, passant de pauvre à riche.
