Definitions

  • the pressure inside the cylinders of the internal combustion engine tends to be more negative than that during the usual fuel cut.
  • the evaporation of the lubricating oil used in the internal combustion engine through the lubricating oil path (for example, a path from the oil pan to the inner wall of the cylinder) leading to the interior of the cylinder is enhanced and the lubricating oil is unnecessarily consumed.
  • This enhanced consumption of the lubricating oil corresponds to the additional consumption inside the cylinders caused by the opening degree of the throttle valve. Such an additional consumption is undesirable since it results in the increased lubricating oil consumption amount.
  • the ECU 10 stores in the memory a correlation between the temperature Tg of the filter 4 and the temperature of exhaust flowing from the filter 4 and a correlation between the PM collected amount in the filter 4 and the difference in exhaust gas pressure between zones upstream and downstream of the filter 4, which have been specified by tests conducted in advance, as respective control maps, and acquires the filter temperature Tg and collected PM amount Mp by accessing the respective control map during the processing of S101. In a case where the processing of S101 is ended, the processing advances to S102.
  • a threshold for determining whether or not such temperature of the filter 4 has been reached corresponds to the aforementioned predetermined threshold temperature. In a case where a positive determination is made in the processing of S102, the processing advances to S103, and in a case where a negative determination is made, the processing advances to S107.
  • the three-way catalyst 3 can lose the exhaust purification function thereof due to the fuel cut processing.
  • the processing advances to S202, and in a case where a negative determination is made, the processing advances to S210.

Abstract

Au moins un état anormal d'un filtre est évité avec précision lorsqu'une MP collectée dans le filtre est oxydée et retirée par traitement de coupure de carburant dans un moteur à combustion interne d'un système d'allumage par étincelle. L'air est fourni à un débit d'air habituel dans le filtre en stoppant l'injection de carburant dans le moteur à combustion interne et en définissant le degré d'ouverture d'un papillon des gaz à une valeur prédéterminée, et la matière particulaire collectée dans le filtre est oxydée et retirée. Dans un cas dans lequel il est déterminé qu'une température atteinte estimée, qui est la température que l'on estime que le filtre atteindra, lorsque l'oxydation et le retrait de la matière particulaire sont réalisés au débit d'air habituel dépasse une température de détermination d'anomalie prédéterminée associée à l'état anormal du filtre, le débit d'air réel dans le filtre lorsque l'oxydation et le retrait de la matière particulaire sont réalisés est réduit de manière à atteindre un débit de suppression d'augmentation de température qui est inférieur au débit d'air habituel.
