ABSTRACT:
A plastic molded fuel rail includes a plurality of core fuel injector assemblies molded within the fuel rail. Each core fuel injector assembly includes a magnetic core, electrical coil bobbin having electrical contacts extending therefrom, and axial fuel passageway. The magnetic core, coil bobbin assembly, and electrical contacts are hermetically sealed from the fuel passageways. An armature and sleeve including a needle and seat valve are inserted into the core fuel injector assemblies to provide fuel injectors. Trimming resistors are appropriately selected connected in series between each fuel injector and a corresponding electronic driver to achieve substantially uniform fuel flow through each fuel injector of the fuel rail.
