An assembly for an air assist fuel injection system have a rail configured to fluidly communicate pressurized gas to a fuel pressure regulator and to an air assist fuel injector of the system. The assembly further includes a cover configured to fluidly communicate fuel to the fuel pressure regulator and to a fuel injector of the air assist fuel injection system.

Methods and assemblies for delivering fuel and gas in air assist fuel injection systems

A cover that covers at least a portion of a fuel pressure regulator of an air assist fuel injection system and fluidly communicates pressurized gas to the fuel pressure regulator.

A fuel injector assembly comprises a fuel injector having an inlet end and an outlet end, and further having an associated fuel rail assembly. An o-ring seal is located approximately at the inlet end to prevent fluid from leaking out of the fuel injector and the fuel rail assembly. A groove in the inlet end is located above the o-ring seal, and a retainer member is constructed to be received into the groove to provide positional constraint to the o-ring seal.

A fuel injector has a metal housing with grooves formed adjacent the interface of the metal housing and a plastic overmold. By extending the overmold around the grooves, fluid migration past the interface of the overmold and metal housing is prevented. Fluid migration is also prevented in the calibration hole of the injector by forming a thin layer of plastic material at the base of the hole which, when compressed during staking and calibration, remains as a layer overlying the metal portions of the inlet connector. The terminal boss for the windings of the injector also has a plurality of grooves which during the plastic encapsulation process, are filled with plastic materials, hence also inhibiting fluid migration past the interface.
