とする多吸気路式内燃機関の吸気装置。In a multi-intake passage internal combustion engine in which the intake passage of each cylinder is separated midway by a separation partition into a first intake passage for swirl generation and a second intake passage for securing output, both intake passages are connected to the starting end of the separation partition. A single common intake control valve for controlling opening and closing of the passage is rotatably mounted, and a fuel injection valve is provided approximately in the middle of the intake passage upstream of the intake control valve, and the intake control valve is connected to the second intake passage. There is a fully closed position (first position) in which the valve is fully closed and the first intake passage is slightly opened, a fully open position (second position) in which both intake passages are fully opened, and a second position in which the valve is fully closed and the first intake passage is slightly opened. An intake system for a multi-intake passage type internal combustion engine, characterized in that it can take a third position in which the first intake passage is controlled to open according to a valve opening angle while the intake passage is fully closed.
