    • PROBLEM TO BE SOLVED: To accurately determine that an exhaust gas recirculation (EGR) valve is opened and fixed, in an internal combustion engine which sprovided with an exhaust gas recirculating device for supplying the exhaust gas of an exhaust system to an air inlet system. SOLUTION: When the load factor kl of the engine is less than a predetermined value α (S410), and when a rate of an engine torque Te, which is actually output to a target torque Te* of the engine, is less than a predetermined value β (a temporary abnormal determining flag Ftmp is 1) and an engine request power Pe* is 0 (S430-S470), a torque Tset for determination is set to be the target torque of the engine (step S480); after a predetermined time T1 has elapsed (S490), the engine torque Te and a predetermined value γ are compared (S500); and if the engine torque Te is less than the predetermined value γ, the EGR valve is determined as being opened and fixed. As a result, it is possible to accurately determine that the EGR valve has been opened and fixed, without being influenced by the load fluctuation. COPYRIGHT: (C)2010,JPO&INPIT
