    摘要: An air intake structure is provided with an air intake control valve (20) disposed in the air intake passage (13). The air intake control valve (20) has a valve element (23) pivotally mounted at one end adjacent to a passage wall of the air intake passage (13).
    The air intake control valve (20) is configured to control a gas flow based on the rotational position of the valve element (23). A horizontal partitioning plate (25) extends along the flow direction of an intake air. The horizontal partitioning plate (25) can be stationary or moveable with the valve element (23). Optionally, the valve element (23) has a swirl-producing notch (23c) and a vertical partitioning plate (26) extends substantially perpendicular to the horizontal partitioning plate (25) from a position corresponding to a vertical side edge (23f) of the swirl-producing notch (23c) when the air intake control valve (20) is fully closed. The vertical partitioning plate (26) can be stationary or moveable with the valve element (23).

    摘要: An internal combustion engine includes an intake port (5) leading to an engine cylinder (2). The intake port is divided into first and second passage section by a partition (11) extending in the intake port in a longitudinal direction of the intake port. A gas motion control valve (31) is arranged to open and close an upstream end of the second passage section (5B). A connection passage (12) connects an upstream end portion of the second passage section (5B) to the first passage section (5A). A fuel injector (41) is directed to inject fuel toward a valve opening of the intake valve through a space (5C) on the downstream side of the downstream end of the partition (11).

    摘要: An intake apparatus for an internal combustion engine, including a partition (11) dividing an intake port (5) into a first passage (5A) and a second passage (5B), and a gas motion control valve (31) including a rotatable valve element disposed upstream of the partition (11) and spaced from an upstream end (11b) thereof. The gas motion control valve (31) has a full-closed position where the valve element prevents intake air from flowing into the second passage (5B) and a full-open position where the valve element allows the intake air to flow into the second passage (5B). The valve element is inclined so as to guide a flow of the intake air to the first passage (5A) when the gas motion control valve (31) is in the full-closed position. The valve element and the partition cooperate with each other to define an interspace (12) therebetween when the gas motion control valve (31) is in the full-closed position.
