摘要:
A selective catalytic reduction system that can defrost urea aqueous solution without interruption of warm air of an engine or heating of a vehicle cabin. The system includes a defrosting control unit to open a tank heater valve at the time of starting the engine and close the tank heater valve when the temperature of the urea aqueous solution detected by a temperature sensor reaches a predetermined defrosting completion determination value, and a warm air priority control unit to prohibit the opening of the valve by the defrosting control unit when the temperature of the cooling water is less than a predetermined defrosting permission value and permit the opening of the valve by the defrosting control unit when the temperature of the cooling water is equal to or more than the defrosting permission value.

摘要:
In the exhaust gas purification system, a diesel particulate defuser (“DPD”) for trapping particulate matter (“PM”) in exhaust gas is connected to an exhaust pipe of an engine to automatically regenerate the DPD by raising a temperature of the exhaust gas from the engine by carrying out post injection when an amount of PM in the DPD exceeds a predetermined amount. Further, the system includes detecting the temperature of the exhaust gas during DPD regeneration when the DPD is automatically regenerated, calculating a deviation between the detected temperature of the exhaust gas and a target temperature for the DPD regeneration, and controlling a quantity of the post injection by resetting an integral control term used in a PID control to zero when running mode automatic regeneration is shifted to idling mode automatic regeneration after a vehicle is stopped, when PID-controlling the quantity of the post injection based on the deviation.

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.

In case of emergency regeneration, i.e. any one of forced regeneration after a judgment is made that purification is insufficient in purification judgment after ending forced regeneration, forced regeneration after time has expired before completing of forced regeneration, or forced regeneration when the pressure difference across a DPF exceeds a predetermined first judging pressure difference under a state where traveling distance of a vehicle is shorter than a predetermined distance for judgment an alarm for urging manual regeneration is issued, and wherein when manual regeneration is designated thereafter manual regeneration is performed and when predetermined conditions are satisfied without the reception of a designation of manual regeneration, automatic regeneration is performed. In forced regeneration of the DPF for purifying PM in exhaust gas, forced regeneration is performed surely even if manual regeneration is not selected at the time of emergency regeneration, and convenience is enhanced by reducing burden on a driver.

摘要:
In forced regeneration control of an exhaust gas purification device a number of data for injection control, such as a number of meshes of a data map and a number of data maps for multi injection control, is decreased while occurrence of torque shock, which is a rapid fluctuation of a generated torque, is avoided. In this forced regeneration control, when an operation state of an internal combustion engine is a high-load operation state, the normal injection control by stopping the multi injection is carried out and, according to a rotation speed and a load of the internal combustion engine, a region for control is divided into a multi-injection control region, a transition region, and a normal injection control region. In the transition region, data for injection control obtained by interpolation of data for injection control on the multi-injection control region side and data for injection control on the normal injection control region side is used.
