PROBLEM TO BE SOLVED: To provide an intake air flow control device for an internal combustion engine performing proper handling to prepare for start of an engine, when there is a possibility of fixing of an intake air flow control valve. SOLUTION: In the intake air flow control device for an internal combustion engine 20, an intake air flow control valve 7 controlling an intake air flow AR is disposed in an intake passage 2. The intake air flow control device comprises: a valve temperature detection means 15 detecting a temperature of the intake air flow control valve 7; and a valve opening change means 10 changing opening of the intake air flow control valve based on the valve temperature detected by the valve temperature detection means. Since the valve opening change means changes the opening of the intake air flow control valve based on the valve temperature detected by the valve temperature detection means, the control device can perform needed response to a possibility of the fixing of the intake air flow control valve, and can secure output after the start of the internal combustion engine even if the intake air flow control valve is fixed. On the other hand, the control device can respond to improvement in combustion and emission when a possibility of the fixing is low. COPYRIGHT: (C)2008,JPO&INPIT
