摘要： A coupling for suspending a fuel injector from a fuel rail assembly of an internal combustion engine includes a collar that mates with the fuel injector and a retainer clip that engages with the collar thereby mechanically connecting the fuel injector to the fuel rail assembly. The retainer clip includes windows to enable even load distribution upon the socket flange when assembled. Features are integrated in the collar to facilitate correct alignment of the injector relative to the fuel rail. Paired together, the retainer clip and the collar enable a secure, and a keyed fuel injector-to-fuel rail connection that is able to withstand high pressure separating loads.

摘要： An upper guide system for a solenoid actuated fuel injector of an internal combustion engine includes an armature and a guide ring having a cylindrical shape and surrounding the armature and positioning the armature in a radial direction. The location of the upper guide system is substantially in the same axial location as the radial magnetic forces imposed on the armature. Features such as flutes or grooves are disposed on an outer diameter surface of the armature and/or holes through a body portion of the armature. Accordingly, the response performance of the solenoid actuated fuel injector is improved.

摘要： A protection device for a lower guide system of a fuel injector includes a debris shield deflecting a fuel flow around a lower guide system and a particle trap collecting particles contained within the fuel flow. By deflecting the fuel flow towards flow passages around the lower guide system, the particles contained in the fuel flow are prevented from entering a lower guide area, such as a radial gap between the stationary components of the lower guide system and the moving component of the valve assembly. The particle trap may be defined in a lower housing of the fuel injector or may be integrated in the debris shield. The debris shield may be integral with a valve assembly or may be a separate component. A permeable area may be integrated in the debris shield to enable partial flow therethrough.

摘要： A fuel rail damper includes a hollow member having a first end and a second end, opposing first and second sides, a first face and a second face interconnecting and spacing apart the first and second sides, and a width. Each of the first and second ends are sealed in an air tight manner to thereby define a chamber in conjunction with the first and second sides and the first and second faces and wherein the widths of the ends do not substantially exceed the hollow member width.

摘要： A fuel rail permeant collection system includes a substantially impermeable enclosure surrounding a fuel rail on an internal combustion engine. Preferably, the enclosure is in communication with air intake means for the engine, for example, the intake manifold or runners from the manifold to the engine cylinders, such that fuel collected by the enclosure can be evaporated and passed into the intake means for combustion by the engine. The system may be included in a vehicle vapor purge circuit from a fuel tank emissions-control canister system.
