    • A fuel injector for an internal combustion engine is disclosed. The injector has a valve body, an injection hole which has a width larger than a height thereof, and a fuel reservoir on the downstream side of a seat portion of the valve body. The fuel reservoir has a side surface and a bottom surface. One part of the side surface imparts one velocity component oriented in the direction of width in the injection hole to the fuel flow along the one part of the side surface. Another part of the side surface imparts another velocity component oriented in the direction of width in the injection hole to the fuel flow along the another part of the side surface. The bottom surface is formed at right angles with the center axis of the injection hole. The injection hole is communicated with the fuel reservoir via the bottom surface thereof.
    • 公开了一种用于内燃机的燃料喷射器。 喷射器具有阀体,具有大于其高度的宽度的喷射孔和在阀体的阀座部分的下游侧的燃料储存器。 燃料储存器具有侧表面和底表面。 侧面的一部分将沿着喷孔的宽度方向定向的一个速度分量赋予沿着侧表面的一部分的燃料流。 侧表面的另一部分赋予另一速度分量,该速度分量沿喷射孔中的宽度方向定向到沿着侧表面的另一部分的燃料流。 底表面与注射孔的中心轴线成直角形成。 注入孔经由其底面与燃料储存器连通。

    • In a fuel injector for an internal combustion engine having a valve body, an injection hole and a fuel reservoir on the downstream side of a seat portion of the valve body, an opening on the outer side of the injection hole has a width generally larger than a height thereof, the width of the injection hole is gradually narrowed inward so that the fuel is injected at a predetermined angle in the direction of width, the height of the injection hole is nearly uniform in the direction of injecting the fuel within the predetermined angle in the direction of width, a through hole is formed at the center portion of the injection hole in the direction of width, and the through hole is communicated with said fuel reservoir and has a height larger than the height of the injection hole.
    • 在具有阀体,喷射孔和在阀体的座部的下游侧的燃料储存器的内燃机的燃料喷射器中,喷射孔的外侧的开口的宽度通常大于 其高度,喷射孔的宽度向内逐渐变窄,使得燃料沿宽度方向以预定角度喷射,喷射孔的高度在将燃料喷射到预定角度内的方向上几乎是均匀的 在宽度方向上,在喷射孔的中心部分沿宽度方向形成通孔,并且通孔与所述燃料箱连通并且具有比喷射孔高度高的高度。
