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.
