    摘要： In regeneration control in a manual regeneration mode, when a first exhaust gas temperature of an exhaust gas flowing into an oxidation catalyst device is higher than a predetermined determining temperature and an exhaust gas temperature flowing into a DPF device is higher than a predetermined determining temperature and when an intake temperature becomes higher than a predetermined third determining temperature, second exhaust gas temperature control carrying out post injection in addition to multi injection is stopped and switched to third exhaust gas temperature rise control carrying out the post injection in addition to normal injection. Thus, temperature rise of an engine cooling water can be restricted without stopping an air conditioner, and possible overheating of the engine can be prevented.

    摘要： In regeneration control in a manual regeneration mode, when a first exhaust gas temperature (Tg1) of an exhaust gas flowing into an oxidation catalyst device (12a) is higher than a predetermined determining temperature (Tc1) and an exhaust gas temperature (Tg2) flowing into a DPF device (12b) is higher than a predetermined determining temperature (Tc2) and when an intake temperature (Ta) becomes higher than a predetermined third determining temperature (Tc3), second exhaust gas temperature control carrying out post injection in addition to multi injection is stopped and switched to third exhaust gas temperature rise control carrying out the post injection in addition to normal injection. Thus, in the regeneration control in the manual regeneration mode of a continuous regeneration type DPF device (12) of an engine(10), temperature rise of an engine cooling water can be restricted without stopping an air conditioner, and possible overheat of the engine (10) can be prevented.

    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： 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： When an internal combustion engine is in a low rotation speed driving condition, a duration of the low rotation speed driving condition is measured, and when this duration exceeds a predetermined time, the forced regeneration control is performed. Thus, even when an exhaust flow rate is small and an estimation of a particulate matter accumulated amount due to a pressure difference between front and back sides of a filter is difficult, a forced regeneration time can be accurately judged, the deterioration of fuel efficiency that is caused by excessive trapped particulate matter can be avoided, and thermal runaway that is caused by the excessive particulate matter, and the melting damage of the diesel particulate filter due to this thermal runaway, can be prevented.

    摘要： In an exhaust gas purification system (1) for conducting control of raising temperature of a DPF (12b) by supplying an unburned fuel to an upstream side of an oxidation catalyst to oxidize it, a minimum value (Qumin) of a first upper limit value (Qu1) acquired by subtracting a fuel injection amount (Qe) for in-cylinder combustion from a first combustible fuel amount (Qa1) limited by an air/fuel ratio, a second upper limit value (Qu2) acquired by subtracting the fuel injection amount (Qe) for in-cylinder combustion from a second combustible fuel amount (Qa2) limited by an atmospheric pressure, and a third upper limit value (Qu3), which is a third combustible fuel amount (Qa3) which can be oxidized by the oxidation catalyst limited by a catalyst temperature index temperature (Tg1, Tg2) and an engine speed (Ne) is set as an upper limit value (Qu) for the unburned fuel supply amount (Qp). By this arrangement, at forced regeneration of the DPF (12b), the unburned fuel supplied into an exhaust gas is surely oxidized and generation of white smoke is prevented regardless of an operation state of an internal combustion engine (10).
