ABSTRACT:
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.
