FUEL INJECTION VALVE

WIPO Patent Application WO/1994/002736

A1

A fuel injection valve adapted to bring a fuel to be atomized injected from a fuel injection port into collision with supplementary air introduced from the outside, and accelerate the pulverization and atomization of the fuel is provided with injected fuel guide bores into which the fuel to be atomized is introduced in each of desired directions. Owing to this arrangement, the injected fuel from the fuel injection port impinges upon the supplementary air and the resultant mixture is introduced into the injected fuel guide bores as the pulverization and atomization of the fuel are accelerated, and the fuel diffusing and injecting direction is restricted by the inner surfaces of the injected fuel guide bores. Accordingly, the cross-sectional shape of the injected fuel is controlled to an optimum shape, and the deposition of the fuel on the inner surface of a suction port is reduced. Consequently, the fuel combustion condition can be improved, and , especially, the reduction of generation of HC and the improvement of fuel efficiency can be effected.
