ABSTRACT:
A fuel injection valve for an internal combustion engine includes an injector body and an adapter. The injector body includes a single fuel injection hole and the adapter includes a concave portion defining a dead volume portion and a pillar extending from a bottom surface of the concave portion toward the fuel injection hole formed in the injector body. Fuel injected through the fuel injection hole into the dead volume portion collides with a top surface of the pillar to form a cone-like fuel flow pattern and a large portion of the fuel can directly flow into injected fuel paths formed in the adapted without attaching to and collecting on surfaces of various portions of the adapter. Thus, stable fuel injection from the injected fuel paths can be obtained.
