Abstract
A fuel injector has a thin disc orifice member through which fuel exits the injector for entrainment with combustion air. The thin disc orifice member has a centrally disposed dimple that contains the orifice pattern. The orifice pattern is asymmetrical about the axis of the dimple thereby enabling the injector to be tilted to a desired orientation for directing the stream from each orifice of the pattern toward a desired target zone. The ability to tilt a fuel injector in this manner enables a fuel injector to be disposed in the most favorable orientation with respect to the engine, for example reducing the protrusion height of the fuel injector above the engine.
