Summary:PROBLEM TO BE SOLVED: To resolve a problem that intake mixing gas adheres and consolidates in a throttle valve causing failure of the throttle valve by placing a gas introducing part immediately below the valve to enhance the mixing degree of the gas to the intake air. SOLUTION: The gas introducing part 4 is provided in an air connector 2 on the side apart from the throttle valve 1 to blow out the intake mixing gas in the direction B against the intake air flow A flowing in the connector 2. The introducing part 4 is disposed at the separated side of an opening 5 from the center α of the connector 2. Thus, the gas hardly adheres to the valve 1, reducing the failure probability of the valve than before. The mixing degree of the air with the gas is enhanced before flowing into a surge tank 3, thereby suppressing the dispersion of an air-fuel ratio supplied to each independent port 6.
