ABSTRACT:
A fuel injection valve includes an injector body having a fuel injection hole and an adapter having a fuel collision surface, two air injection holes and two injected fuel paths. The fuel injected from the fuel injection hole flows in a slug-like pattern and collides with the fuel collision surface where the fuel is atomized a first time. Then, the fuel flows in a direction away from an axis of the adapter in a membrane-like pattern getting thinner in thickness to be finally broken to pieces, that is, to be atomized a second time. The air injected from the air injection holes collides with the membrane-like pattern of fuel to be atomized a third time before the fuel goes out of the injected fuel paths.
