摘要： An accurate determination of deterioration of a NOx storage reduction catalyst. A supply device supplies a reducing agent to the NOx catalyst to change an air fuel ratio of an exhaust gas passing through the NOx catalyst, an NH3 detection device detects NH3 in the exhaust gas at the downstream side of the NOx catalyst, a control device adjusts an amount of the reducing agent so that the air fuel ratio of the exhaust gas becomes a predetermined rich air fuel ratio, and a determination device makes a determination that the NOx catalyst has deteriorated, when a detected value of the NH3 detection device becomes equal to or greater than a threshold value, at the time of supplying the reducing agent while adjusting the amount of the reducing agent so that the air fuel ratio of the exhaust gas becomes the predetermined rich air fuel ratio.

摘要： An internal combustion engine, in which an NOX selective reducing catalyst (15) is arranged inside an engine exhaust passage, and aqueous urea stored in an aqueous urea tank (20) is fed to the NOX selective reducing catalyst (15) to selectively reduce the NOX. The aqueous urea tank (20) comprises a main tank (20a) and a sub tank (20b) arranged inside the main tank (20a). The aqueous urea in the sub tank (20b) is sent to an aqueous urea feed valve (17). When the aqueous urea tank (20) should be refilled with aqueous urea, the sub tank (20b) is refilled with aqueous urea. It is detected by a level sensor (40) if the aqueous urea in the aqueous urea tank (20) is refilled. When it is judged that the NOX purification rate falls below an allowable level at the time of engine operation right after the aqueous urea in the aqueous urea tank (20) has been refilled, it is judged that the refilled aqueous urea is abnormal.
