摘要： Provided is a nozzle plate for a fuel injection device which can inject fuel flowed out from a fuel injection port of a fuel injection device in a sufficiently atomized manner. According to the nozzle plate 3 of the present invention, a portion of fuel flowed out from an fuel injection port of the fuel injection device is atomized by impinging on an interference body 16 and, at the same time, the flow of the portion of fuel is sharply bent and impinges on fuel which straightly advances and passes through a nozzle hole 7 and an orifice 8 thus turning the flow of fuel which straightly advances and passes through the nozzle hole 7 and the orifice 8 into a turbulent flow. Further, according to the nozzle plate 3 of the present invention, both end portions of the orifice 8 form non-rounded sharpened corner portions 22 and hence, a liquid film of fuel injected from the corner portions 22 and areas in the vicinity of the corner portions of the orifice is formed into a thin sharpened and pointed state whereby an end portion of the liquid film of fuel injected from the orifice 8 is easily atomized due to a friction between the end portion of the liquid film of fuel and air. Accordingly, the nozzle plate 3 of the present invention can further improve the level of atomization of fuel compared to conventional nozzle plates.

摘要翻译：本发明提供一种燃料喷射装置用喷嘴板，其能够以充分雾化的状态喷射从燃料喷射装置的燃料喷射口流出的燃料。根据本发明的喷嘴板3，从燃料喷射装置的燃料喷射口流出的燃料的一部分通过撞击在干涉体16上而被雾化，并且与此同时，燃料的一部分急剧弯曲并撞击直线前进并通过喷嘴孔7和喷嘴8的燃料，从而使直线前进并通过喷嘴孔7和喷嘴8的燃料的流动变成湍流。此外，根据本发明的喷嘴板3，孔8的两个端部形成不圆的尖角部22，并且因此从角部22和拐角附近的区域喷射的燃料的液膜由于燃料液膜的端部与空气之间的摩擦，从节流孔8喷射的燃料液膜的端部容易雾化，所以节流孔的一部分形成为尖锐而尖锐的状态。因此，与传统的喷嘴板相比，本发明的喷嘴板3可以进一步提高燃料的雾化水平。

摘要： The invention relates to a fuel-injection valve, in particular a high-pressure injection valve for directly injecting fuel into a combustion chamber of a compressed-mixture, spark-ignition internal combustion engine. Said valve is characterised in that an outlet opening (23) is provided downstream of the valve seat (20), the downstream end of said opening having a slit-forming element (30) that to a great extent closes the outlet opening (23). A slit-type flow outlet (35), through which a fuel spray can be discharged in a fan-type jet, is formed between the slit-forming element (30) and a front face (34) of the valve seat body (16).

摘要： The invention relates to an atomising disc (23) with at least one inlet (40), at least one outlet (42) and an integral passage for fuel between the inlet (40) and the outlet (42). A throughflow sensor (50, 51, 50`, 51`, 150, 151) is arranged in the atomising disc (23), upstream of a metering diameter of the fluid passage. The flow through the atomising disc (23) during flowing operation may thus be regulated and actively adjusted at any time. The atomiser disc (23) is particularly suitable for application in a fuel injection valve, in particular, a high pressure injection valve for direct injection of fuel into a combustion chamber of a mixture-compressing, spark-ignited internal combustion engine.

摘要： The invention relates to a fuel injection valve, characterized in that a perforated disk (23) is fitted, on a valve seat body (16) having a fixed valve seat (29), in particular on its downstream face (17), the opening geometry of which is limited by the valve seat body, so that the flow conditions in the perforated disk (23) are influenced by the valve seat body (16). The valve seat body (16) covers an upper intake area (40) of the perforated disk (23) at least in such a way that the downstream outlet openings (39) of the perforated disk are covered over. The fuel injection valve is particularly suitable for use in fuel injection installations of mixture compressing, spark ignition internal combustion engines.

摘要： The invention relates to a perforated disk characterized in that a complete passage for fluid is constructed. Said passage comprises an inlet opening (40), outlet openings (42) and at least one channel (cavity) (41) situated between the inlet and outlet openings. At least three functional surfaces (45, 46, 47) of the perforated disk (23) with one respective characteristic opening structure (40, 41, 42, 43) are constructed on top of one another by means of galvanic metal precipitation (multi-layer galvanization) so that the perforated disk (23) is available in one piece. In the lower functional surface (45), gas delivery openings (43) are configured through which gas can be delivered in the direction of the fluid which is to be injected, so that the fluid can be finely sprayed. Said outlet openings (42) are part of the gas delivery openings (43). The perforated disk (23) is especially suitable for the use in injection valves for mixture compressed, externally supplied ignition internal combustion engines.

摘要： The invention relates to a fuel injection system for internal combustion engines, comprising at least one fuel injection valve (25) which injects fuel into a fuel chamber (19) defined by a cylinder wall (17) in which a piston (16) is displaced. A spark plug (20) protrudes into the combustion chamber (19), and the fuel injection valve (25) is arranged in said combustion chamber (19) in the region of a gas inlet valve (23) towards the cylinder wall (17). Said fuel injection valve (25) produces a plurality of jets of fuel (28, 29, 30), at least one of said jets (29) being tangentially oriented in the region of the spark plug (20).
