  • Patent number: 10036295
    Abstract: A aqueous urea solution supply device for an engine is provided with a tank that stores aqueous urea solution, a valve configured to add the aqueous urea solution to exhaust gas, and a passage configured to supply the aqueous urea solution in the tank to the valve. When a pressure of the aqueous urea solution supplied to the valve is equal to or lower than a predetermined pressure and the amount of the aqueous urea solution in the tank is equal to or smaller than a predetermined threshold, an electronic control unit determines that the aqueous urea solution in an amount required for cooling of the valve cannot be supplied from the tank to the valve and executes a return control for returning the aqueous urea solution in the valve to the tank.
