た内燃機関の吸気制御装置。An intake control valve for controlling the flow path of intake air in the intake port is provided in the intake port, and the rotation axis of the intake control valve is arranged eccentrically to one side of the intake port from the intake port axis. In the intake control device for an internal combustion engine, the rotation of the intake control valve is controlled according to the engine load, and a partially cylindrical groove centered on the rotation axis of the intake control valve is formed on an inner wall surface of one side of the intake port. The valve body of the intake control valve is formed from a partial cylindrical body with a sector-like cross section having a diameter slightly smaller than the diameter of the groove, and the cylindrical outer circumferential surface of the valve body is connected to the intake port inlet during low load operation. An intake control device for an internal combustion engine that directs the intake air toward the opening.
