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 air intake device of an internal combustion engine comprises a cylinder head having therein two intake ports that are adapted to connect to a cylinder of a cylinder block; and a single partition plate that extends across both the two intake ports so that each of the two intake ports is divided into first and second air passages.

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.

摘要:
The present invention provides a fuel injection device comprising an intake pipe (18) having interior wall surfaces (18b) for providing air from an upstream side to a downstream side and a fuel injection port (52) disposed in the intake pipe (18) between the surfaces for providing fuel into the intake pipe (18) and an air guide member (30) disposed in the intake pipe (18) in a plane substantially parallel to the surfaces for guiding air separately towards an air flow layer passage (18c) and a main air passage (18d) wherein the air guided towards the air flow layer passage (18c) has a speed at least greater than the air guided towards the main air passage (18d).
摘要:
L'invention propose un système d'admission de gaz dans une chambre de combustion (22), qui comporte un conduit d'admission (24) des gaz, du type qui comporte un tronçon amont (26), et qui se divise en deux tronçons aval (28, 30) qui débouchent dans la chambre (22) par deux orifices (32, 34) chacun obturés par une soupape d'admission (36, 38) respectivement, et du type dans fequel l'intérieur du tronçon amont (26) comporte au moins une lame de séparation (60) de façon à former deux couloirs d'écoulement (62, 64) correspondant aux tronçons aval (28, 30), et qui comporte une zone de passage (66) des gaz entre les deux couloirs (62, 64), caractérisé en ce qu'au moins le premier tronçon aval (28) comporte une cloison (72) qui le divise en deux zones d'admission (68, 70) pour que, lorsque le second tronçon aval (30) est au moins partiellement obturé par la soupape (38) correspondante, le débit des gaz est plus élevé dans une des zones d'admission (68).
