ABSTRACT:
A fuel injector valve assembly primarily for use with a diesel engine, including an improved barrel unit comprising an annular, generally cylindrical body having a plurality of internally-disposed, transversely and longitudinally-arranged passageways for the flow of fuel therein. The internal fuel passageways and ports are substantially rectangular rather than round. As a result, the injector operates at lower temperatures. A positive correlation has been discovered between lower injector temperatures in a diesel engine and lower exhaust smoke emission. A positive correlation has been discovered between lower injector temperature and better fuel economy and better horsepower output.
