ABSTRACT:
A solenoid type fuel injection valve for injecting fuel into a plurality of intake ports including a pintle provided at a lower end of a needle valve to protrude into a fuel atomizing space formed at a lower portion of a fuel injection hole, so that the fuel is atomized by collision against the pintle after passing through the fuel injection hole, and the atomized fuel is introduced into a fuel distributing space having an inclined wall surface. A pair of fuel spray guides are supported at a lower end of a cap through support arms, and a fuel injection passage having a horseshoe-like cross-sectional shape is formed around an outer periphery of each of the fuel spray guides. A fuel spray colliding against the inclined wall surface is divided into two flows which are conducted into the pair of fuel injection passages and injected equally into a bifurcated intake port.
