Abstract
An air intake structure is provided with an air intake control valve disposed in the air intake passage. The air intake control valve has a valve element pivotally mounted at one end adjacent to a passage wall of the air intake passage. The air intake control valve is configured to control a gas flow based on the rotational position of the valve element. A horizontal partitioning plate extends along the flow direction of an intake air. The horizontal partitioning plate can be stationary or moveable with the valve element. The valve element has a swirl-producing notch and a vertical partitioning plate extends substantially perpendicular to the horizontal partitioning plate from a position corresponding to a vertical side edge of the swirl-producing notch when the air intake control valve is fully closed. The vertical partitioning plate can be stationary or moveable with the valve element.
