  • Patent number: 8495861
    Abstract: An object of the present invention is to provide a technology that enables detection of a fault of a PM trapper with improved accuracy. In the present invention, a pressure sensor 20 that measures a differential pressure across a PM trapper 11 is provided, and a fault of a PM trapper is determined based on an amount of change in the differential pressure across the PM trapper 11 between two different operation states of an internal combustion engine 1 in which the ambient temperature around the pressure sensor 20 falls within a specific temperature range. Since variations in the offset error of the differential pressure sensor 20 caused by changes in the ambient temperature around the differential pressure sensor 20 is made small, the amount of change in the differential pressure across the PM trapper 11 can be measured more accurately, and a fault of the PM trapper 11 can be detected with improved accuracy.

  • Patent number: 8074442
    Abstract: An object of the invention is to realize a method of determining an abnormality in a particulate filter (5) capable of trapping and oxidizing particulate matter contained in exhaust gas in which even a minor abnormality in which small quantity of particulate matter can pass through the particulate filter (5) can be determined with a high degree of accuracy. To achieve this object, the abnormality determination method according to the invention, the transition of the inflowing exhaust gas temperature in and the outflowing exhaust gas temperature out of the particulate filter (5) during deceleration operating, and the degree of decrease in the outflowing exhaust gas temperature relative to the inflowing exhaust gas temperature is computed based on the transition. If the degree of decrease exceeds a threshold value, it is determined that the particulate filter (5) is abnormal.

  • Publication number: 20090205318
    Abstract: An object of the present invention is to provide a technology that enables to detect a fault of a PM trapper with improved accuracy. According to the present invention, a plurality of temperature sensors 10 are provided in an exhaust passage 9 just downstream of a PM trapper 17 in such a way that their temperature detection elements are positioned on a plane that is perpendicular to an imaginary center axis of the exhaust passage 9. A change in the radial direction temperature distribution of the exhaust gas flowing out of the PM trapper 17 upon occurrence of a fault in the PM trapper 17 is detected from measurement values of the temperature sensors 10, and a fault of the PM trapper 17 is detected based on this radial direction temperature distribution. Since the measurement values of the temperature sensors 10 are unlikely to be affected by the amount of PM deposited on the PM trapper 17, detection of a fault of the PM trapper 17 can be achieved with improved accuracy.
