    摘要： An exhaust gas purification system has an exhaust gas purification device (12) for purifying components in exhaust gas from an internal combustion engine (10) such as a diesel engine. In order to recover the purification ability of the exhaust gas purification device (12), and in order to prevent oil dilution occurring when post injection is conducted as part of an in-cylinder fuel injection control during an exhaust gas temperature raising control that raises the temperature of exhaust gas, the system performs the following. In a regenerative control for recovering purification ability of the exhaust gas purification device (12), injection quantities (Qp) of post injections are calculated based on previously set map data (Mp), accumulated to calculate a post injection accumulated injection amount (ΣQp), and, when the accumulated injection amount (ΣQp) exceeds a predetermined determination value (Cp), the post injection is stopped to cease the regenerative control.

    摘要： A method and system providing a vehicle condition detection means (38C) for detecting the stopped and traveling state of a vehicle, and when the vehicle condition detection means (38C) detects that the vehicle has stopped during operation of an exhaust gas temperature raising means (351C), closing an exhaust gas throttling valve (16) in addition to continuing the operation of the exhaust gas temperature raising means (351C), and subsequently, when the vehicle's traveling state is detected, opening the exhaust gas throttling valve (16) and continuing the operation of the exhaust gas temperature raising means (351C). Accordingly, in terms of the regeneration of a continuous regeneration-type DPF device (13) capable of significantly reducing the frequency with which the driver is urged to stop the vehicle and perform forced regeneration, the exhaust gas can be efficiently maintained at a high temperature, and reliable burning of PM is possible even for driving patterns featuring frequent waiting at traffic signals in urban areas, even upon transition to the stationary idling condition during automatic traveling regeneration.

    摘要： The present invention concerns a exhaust gas purification system (1), provided with a continuous regeneration-type DPF device (13) having a filter (13b) for collecting PM in exhaust gas (G), provided in an exhaust gas passage (12) of an internal combustion engine (10) provided with an EGR system, for supplying unburned fuel to exhaust gas (G) flowing in the continuous regeneration-type DPF device (13) during the forced regeneration control for regenerating the filter (13b) by forcibly burning PM collected by the filter (13b), characterized by stopping the recirculation of EGR gas (Ge) to the intake passage (14) side in the EGR system, when unburned fuel is supplied to exhaust gas (G) during the forced regeneration control. This prevents the blocking of EGR passage (15) and the sticking of intake valve and so on, caused by the unburned fuel supplied into exhaust gas (G), during the forced regeneration control of the continuous regeneration-type DPF device (13). And this prevents engine troubles caused by these problems.
