Exhaust gas purification device
An exhaust gas purification device comprises a NOx catalyst for purifying NOx contained in exhaust gas by using ammonia as a reducing agent, an ammonia supply device for supplying ammonia to the NOx catalyst, a catalyst temperature sensor for detecting the internal temperature of the NOx catalyst, and a control unit that stops the ammonia supply from the ammonia supply device when the stop condition is satisfied that the internal temperature of the NOx catalyst becomes equal to or higher than first prescribed temperature in the process where ammonia is supplied from the ammonia supply device to the NOx catalyst.
