Abstract:
An exhaust purification device of an engine includes: an exhaust passage; a urea injector supplying urea water into the exhaust passage; a pump device which supplies urea water stored in a urea tank to the urea injector, the pump device capable of performing an operation of recovering the urea water supplied to the urea injector to the urea tank; an SCR catalyst which purifies the exhaust gas using urea; and a controller. The controller controls the pump device such that the supply of the urea water to the urea injector is stopped, and a recovery operation for recovering the urea water in the urea injector to the urea tank is performed in a case where an amount of ammonium adsorbed by the SCR catalyst is larger than a predetermined reference adsorption amount under a condition where an internal temperature of the urea injector reaches a predetermined high temperature.

Claim (Index 5):
The exhaust purification device of an engine according to  claim 1 , wherein\n the controller is configured to perform a control of increasing a supply amount of the urea water to the urea injector in a case where the amount of ammonium adsorbed by the SCR catalyst is not yet larger than the reference adsorption amount under a condition where a temperature of the urea injector reaches the predetermined high temperature.
