Beschreibung
Zusammenfassung:	In an exhaust passage, a pressure detection means is provided on the upstream side of a filter, and an exhaust throttle valve is provided on the downstream side of the filter. And, when the operational state of the internal combustion engine is a steady operational state (in a step S101), the opening amount of an exhaust throttle valve is controlled so that the upstream pressure detected by the pressure detection means becomes a constant value (in a step S103). Selon l'invention, dans un passage d'échappement, des moyens capteurs de pression sont disposés du côté amont d'un filtre et un papillon des gaz d'échappement est disposé du côté aval du filtre. Lorsque l'état de fonctionnement du moteur à combustion interne est stable (étape S101), la quantité d'ouverture du papillon des gaz est réglée de manière que la pression amont détectée par les moyens capteurs de pression devient une valeur constante (étape S103).
