摘要:
A urea removing apparatus has: a determining section that determines whether or not a urea aqueous solution is injected from an injection nozzle when control is performed to inject the urea aqueous solution from the injection nozzle into an exhaust pipe where exhaust gas of an engine flows; a supply control section that controls a pump that supplies the urea aqueous solution to the injection nozzle from a tank that stores the urea aqueous solution, and causes the urea aqueous solution to be supplied from the tank to the injection nozzle in a case that it is determined that the urea aqueous solution is not injected from the injection nozzle; and a temperature control section that performs control to raise the temperature of exhaust gas in a state where the urea aqueous solution supplied from the tank has been poured into the injection nozzle.
