摘要： The disclosed valve has an injector plate (23) arranged downstream of a valve seat (29). The injector plate (23) is characterised in that it has a plurality of narrow fuel discharge slots (40) that are arranged in a star shape in the radial direction but have no common contact point. This arrangement allows fuel to be finely sprayed without requiring additional energy. The breaking down into smallest droplets also results in a further reduction of the exhaust gas emission of an internal combustion engine and in a reduction of fuel consumption. This valve is particularly useful for fuel injection systems spark-ignited internal combustion engines with high compression ratio of the mixture.

摘要： This fuel injection valve has an injector plate (23) arranged downstream of a valve seat (29). The injector plate is characterised in that a plurality of swirl-generating elements (40) are arranged at its inflow side and are followed by at least one uninterrupted ring-shaped slot (45). The swirl-generating elements (40) are arranged in the manner of a blade wheel, in that each individual element (40) extends substantially in the radial direction and is tilted in the circumferential direction, and in that the elements (40) follow each other in a circle. The ring-shaped slot (45) defines the injection geometry. This arrangement allows fuel to be finely and uniformly sprayed without requiring additional energy. The breaking-down into smallest droplets results in a further reduction of the internal combustion engine exhaust fume emission and also in a reduction of fuel consumption. This fuel injection valve is particularly useful for fuel injection systems of high compression ratio, spark-ignited internal combustion engines.

摘要翻译：该燃料喷射阀具有布置在阀座（29）下游的喷射器板（23）。该喷射器板的特征在于，多个产生涡流的元件（40）布置在其流入侧，并且随后是至少一个不间断的环形槽（45）。涡流产生元件（40）以叶轮的方式布置，其中每个单独的元件（40）基本沿径向方向延伸并且沿圆周方向倾斜，并且元件（40）分别跟随其他围成一圈。环形槽（45）限定注射几何形状。这种布置使得燃料能够精细且均匀地喷射而不需要额外的能量。分解成最小的液滴导致内燃机废气排放物的进一步减少并且还减少了燃料消耗。该燃料喷射阀对于高压缩比的燃料喷射系统，火花点火式内燃机特别有用。
