Abstract
A fuel injector for an internal combustion engine is disclosed. In the fuel injector, an opening on the outer side of the injection hole has a width generally larger than a height thereof. The width of the injection hole is gradually narrowed inward so that the fuel is injected at a predetermined angle in the direction of width. The height of the injection hole is nearly uniform in the direction of injecting the fuel within the predetermined angle in the direction of width. A height at both ends of the opening on the outer side of the injection hole is larger than the height at the central portion thereof.
