    摘要： In a control method of an exhaust emission purification system (1) and the exhaust emission purification system (1), an exhaust throttle valve (14) is opened if an engine load reaches at least a predetermined first judgment value during execution of forced regeneration control with said exhaust throttle valve (14) closed when a vehicle is stopping. If the engine load thereby increases during execution of forced regeneration of a DPF (12) for purifying PM (particulate matter) in exhaust gas with the exhaust throttle valve (14) closed when the vehicle is stopping, a good combustion state can be sustained in a cylinder by opening the exhaust throttle valve (14) and taking fresh air into the cylinder of an engine (10).

    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： At regeneration control while a vehicle mounting an internal combustion engine (10) is parked, both an exhaust throttle valve (13) and an exhaust brake valve (18) are used and if a catalyst temperature index temperature (Tg2) is lower than a predetermined first determining temperature (Tc1), first exhaust gas temperature rise control is conducted that the exhaust brake valve (18) is set to a fully closed side and multiple injection is carried out in in-cylinder fuel injection control, while if a catalyst temperature index temperature (Tg2) is equal to the predetermined first determining temperature (Tc1) or above, second exhaust gas temperature rise control is conducted that the exhaust brake valve (18) is set to an open side, the exhaust throttle valve (13) is set to the fully closed side, and post injection is carried out in the in-cylinder fuel injection control. By this arrangement, while temperature rise efficiency of an exhaust gas flowing into a DPF (12) is enhanced, forced regeneration is carried out efficiently in a short time with avoiding overheat or abnormal combustion at the regeneration control of the DPF (12) while the vehicle is parked.

    摘要： In an exhaust gas purification system (1) comprising an exhaust gas purification device (12) having an oxidation catalyst device (12a) carrying an oxidation catalyst and a DPF (12b) arranged in order from an upstream side or a DPF carrying an oxidation catalyst in an exhaust passage (11) of an internal combustion engine (10), in which at regeneration of the DPF (12b), when a catalyst temperature index temperature (Tg2) indicating a temperature of the oxidation catalyst becomes equal to a predetermined determining temperature (Tc1) or above, control of raising a temperature of the DPF (12b) is conducted by supplying an unburned fuel to the upstream side of the oxidation catalyst to thereby oxidize the unburned fuel by the oxidation catalyst, wherein the predetermined determining temperature (Tc1) is changed according to an engine speed Ne of the internal combustion engine (10). By this arrangement, at the regeneration of the DPF (12b), in the regeneration control of raising the temperature of the DPF (12b) by oxidizing the unburned fuel supplied into an exhaust gas by the oxidation catalyst (12a), the unburned fuel supplied into the exhaust gas is surely oxidized and outflow of white smoke is prevented regardless of an operation state of the internal combustion engine (10).
