    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). 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 intake apparatus for an internal combustion engine, including a partition (11) extending in a longitudinal direction of an intake port (5) so as to divide an inside region of the intake port (5) into a first passage (5A) and a second passage (5B), and a gas motion control valve (31) disposed at a downstream end of an intake manifold and adjacent to an upstream end of the partition (11). The gas motion control valve includes a rotatable valve element (33) and has a full-closed position where the valve element fully closes the second passage (5B) of the intake port and a full-open position where the valve element fully opens the second passage (5B) of the intake port. The valve element and the partition cooperate with each other to define an interspace (12) between the valve element (33) and the upstream end of the partition (11) when the gas motion control valve (31) is in the full-closed position.

    摘要: An internal combustion engine includes at least two intake valves per cylinder, and at least two intake ports leading to the intake valves, a first intake port preferably being configured as unthrottled tangential passage and the flow through a second intake port being controlled by means of a first throttle element (11) actuated in dependence of at least one engine parameter, and at least one fuel injector per cylinder injecting fuel into at least two intake ports, wherein in the closed position of the first throttle element at least one leakage aperture will permit a defined minimum flow through the second intake port. To improve emission values of the engine in a simple manner, the first throttle element is positioned downstream of the fuel injector and that at least one leakage aperture is provided in the area impinged on by at least one injection jet, the first throttle element in its closed position forming an obtuse angle (alpha) of greater than 90 ° with a partition wall between the first and second intake port so that the inlet air flow will be diverted towards the first intake port.
