摘要： Even in the case of driving for a long time in the low rotation speed driving condition in which the exhaust flow rate is small and an estimation of the PM accumulated amount due to the pressure difference between the front and the back sides of a filter is difficult, the forced regeneration time can be accurately judged, the deterioration of fuel efficiency that is caused by excessive PM trapping can be avoided, and at the same time, thermal runaway that is generated by the excessive accumulated amount of PM and melting damage of the DPF due to this thermal runaway can be prevented. In the exhaust gas purification system 1 that performs a forced regeneration control by judging a forced regeneration starting time of the DPF 12b from the pressure difference ΔPm between the front and the back sides of the DPF 12b, in the case of detecting that the driving condition of the internal combustion engine 10 is a low rotation speed driving condition, the sustaining time tm of the low rotation speed driving condition is measured, and when the measured sustaining time tm exceeds the predetermined time for judgment tc, the forced regeneration control of the DPF 12b is performed without affecting the pressure difference ΔPm between the front and the back sides of the DPF 12b.

摘要： In in-cylinder fuel multi-injection conducted during forced regeneration of a DPF (12b), control maps for multi-injection are constructed so as to be different for a first gas temperature raising control, which raises a catalyst temperature index temperature (Tg2, Tg1) to a first judgment temperature (Tc1) only by multi-injection, and for a subsequent second exhaust gas temperature raising control, wherein post-injection is conducted in addition to multi-injection to raise a filter temperature index temperature (Tg2) to a second judgment temperature (Tc2). In so doing, exhaust gas flowing into the DPF (12b) can be rapidly raised in temperature when performing forced regeneration of the DPF (12b), thereby shortening the forced regeneration time and improving fuel consumption for forced regeneration.

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.
