    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.

    摘要： An exhaust pipe injection control device for controlling an appropriate fuel injection amount regardless of engine rotation speed. The exhaust pipe injection control device includes: a target injection amount setting unit which sets, according to an engine rotation speed and an exhaust gas flow rate, a target injection amount that is injected in a single injection from an exhaust pipe injector; a base pulse width (“BPW”) map in which a fuel injection time of the exhaust pipe injector is set so that, with respect to the target injection amount and an exhaust pipe injection fuel pressure, fuel in the target injection amount is injected; and an exhaust pipe injection executing unit which performs injection from the exhaust pipe injector by referring to the BPW map based on the target injection amount and the exhaust pipe injection fuel pressure.

    摘要： A selective catalytic reduction (SCR) system that can prevent fixation of urea solution to an interior of a dosing valve when the urea solution is not injected through the dosing valve. An SCR system closes a dosing valve when the exhaust gas temperature is lower than a temperature at which an SCR catalyst becomes active and is provided with a fixation prevention system that opens the dosing valve and controls a supply module to feed the urea solution in the dosing valve back to a urea tank to prevent fixation of the urea solution to the interior of the dosing valve, when the exhaust gas temperature is equal to or higher than a temperature at which the urea solution crystallizes and lower than the temperature at which the SCR catalyst becomes active.

    摘要： 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. An abnormality detector detects an abnormality of the dosing valve and a recovery controller controls a supply module to feed urea solution in the dosing valve back to an urea tank when the abnormality detector detects the abnormality.
