Abstract
For each of the injection holes on the face of a plate member which is disposed in a fuel passage, grooves are provided which run along the circumferential direction of the respective injection holes, and at the positions of the grooves, fuel overflows are formed. As a result, contracted fuel flow portions are formed in the injection holes, so that the maximum flow velocity of fuel is increased at the injection hole outlet portions. Thus, a fuel injection valve for an internal combustion engine is provided, in which the atomization performance near the injection holes is effectively enhanced.
