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) 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).

摘要： The present invention provides a recovery control system that allows a dosing valve to recover from a malfunction to a normal state or a liquid feed line through which urea solution is fed to recover from clogging to a normal state. A recovery control system for allowing a dosing valve 104 to recover from a malfunction to a normal state has abnormality detection means of detecting an abnormality of the dosing valve 104 and recovery control means of controlling a supply module 106 to feed urea solution in the dosing valve 104 back to a urea tank 105 when the abnormality detection means detects an abnormality of the dosing valve 104.

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 (£Qp), and, when the accumulated injection amount (£Qp) exceeds a predetermined determination value (Cp), the post injection is stopped to cease the regenerative control.
