  • Internal combustion engine exhaust gas purifying system
    Patent number: 7210285
    Abstract: An internal combustion engine exhaust gas purifying system (10) having a continuous regenerating diesel particulate filter system (3) on the exhaust passage (2) of an internal combustion engine (1) is constituted by including collected-quantity estimation means (5A) for estimating the quantity of collected particulate matter in a filter (3b) of the filter system for collecting the particulate matter and maximum-fuel-injection-quantity restricting means (5C) for restricting the maximum fuel injection quantity of the internal combustion engine (1) when the quantity of collected particulate matter estimated by the collected-quantity estimation means (51A) is equal to or more than a predetermined judgment value.
    Type: Grant
    Filed: September 10, 2003
    Date of Patent: May 1, 2007
    Assignee: Isuzu Motors Limited
    Inventors: Hitoshi Sato, Naofumi Ochi, Masashi Gabe, Takehito Imai, Takashi Urata
