Abstract
A solenoid-operated fuel injector has a housing forming an enclosure which contains a solenoid coil assembly having electrical terminals extending therefrom via which the fuel injector is connected with a connector for selectively energizing the solenoid coil by electric current to operate the fuel injector. A fuel rail delivers pressurized liquid fuel to a fuel inlet which is at one axial end of the injector. Fuel is injected from the enclosure at an axially opposite nozzle outlet end. A valve mechanism is disposed within the enclosure and is operated by the solenoid coil acting through a spring-biased armature to open and close a flow path through the enclosure. The coil orientation allows the injector electrical terminal to be lowered, so the terminals exit from the bottom of the coil.
