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.

Abstract: An electrical connector for connecting electric wiring to a mating connector of a fuel-rail-mounted electric-operated fuel injector. The connector and the fuel rail have integral formations that serve to assure circumferential orientation of the injector in a socket of the fuel rail and to axially capture the injector in the socket. A snap-catch mechanism releasably locks the connector to the injector and is provided by further integral formations on the wiring connector and the injector connector. In this way, extra attaching parts are not required. The fuel rail assembly has a lower profile which is advantageous from the standpoint of engine compartment packaging in an automotive vehicle.
