Abstract: A fuel injector with an anti-rotation clip for use in conjunction with a twist lock fuel injector inserted into a receiving fuel cup. The clip includes at least one connector leg which extends at least partially over the electrical connector for the fuel injector and locks the clip against rotation relative to the fuel injector electrical connector. A protrusion on a fuel cup arm engages a notch formed in the fuel cup to lock the arm against rotation relative to the fuel cup.

Abstract: A fuel injector for an internal combustion engine having an elongated body with a fuel inlet end and a fuel discharge end. The injector body includes an outwardly extending plate attached at a position between its ends and this plate includes at least one radially outwardly extending tab so that the cross-sectional shape of the plate is noncircular. A fuel cup receives the fuel inlet end of the fuel injector and includes a radially inwardly extending ledge at a mid position of the cavity. This ledge includes a through bore complementary in shape to the shape of the plate so that, with the fuel injector and plate aligned at a predetermined angular assembly position, the plate passes through the ledge upon insertion of the fuel injector into the cavity. Thereafter, rotation of the fuel injector and attached plate to a locking position positions the tabs above the ledge thus locking the fuel injector to the fuel cup.

Abstract: A high pressure fuel pipe construction for an internal combustion engine, such as a direct injection engine. A conduit for the fuel is open at each end and a ball having a throughbore is slidably positioned over one end of the conduit. A reinforcing sleeve is positioned inside the end of the conduit so that the sleeve extends entirely through the ball. The sleeve, ball and the end of the conduit are then brazed together to attach the ball and conduit together. A double chamfer is provided at one end of the ball throughbore to facilitate inspection of the brazing quality. Additionally, a loop is formed in the conduit and a dampener is attached to the loop.

Abstract: A fuel system for a direct injection engine having a fuel rail and a plurality of direct injection fuel injector assemblies mounted to the fuel rail. Each fuel injector assembly includes a mounting surface and a dampener made of a resilient material is disposed around this mounting surface. A bracket is secured to the engine and has a recess for each fuel injector assembly. Each fuel injector assembly is positioned in its associated recess so that at least a portion of the dampener is sandwiched between the fuel injector assembly mounting surface and a complementary mounting surface formed on the recess. A holder secures the injector assembly in its associated recess.

Abstract: A fuel system component for a direct injection internal combustion engine.

Abstract: A supporting mechanism (12A) is used for transfer-ring a target substrate (W) in cooperation with a transfer arm (32), in a semiconductor processing system. The supporting mechanism includes first and second holding portions (38A to 38C, 40A to 40C) each configured to be moved up and down and transfer a substrate to and from the transfer arm. The first and second holding portions are configured to be moved relative to each other in a vertical direction without spatially interfering with each other, and support substrates at substantially the same horizontal coordinate position. The supporting mechanism further includes first and second drives (46, 48) configured to move the first and second holding portions up and down, and a controller (68) configured to control the first and second drives. The controller is arranged to control the first and second drives to alternatively support a substrate by the first and second holding portions.

Abstract: A fluid coupling for a fuel system in a direct injection internal combustion engine having a body with a ball portion and a fluid passageway extending through the ball portion. The body also includes external threads which extend concentrically around the ball. A tube has an outwardly flared end while both a ferrule and a nut are disposed over the tube. The nut includes internal threads which threadably engage the external threads on the body so that, upon tightening, the nut compresses the outwardly flared portion of the tube in between the ferrule and the ball thus sealingly coupling the tube to the body in fluid communication with the passageway formed through the ball.

Abstract: A method and apparatus for attenuating fuel pump noise in a direct injection internal combustion engine. In one proposal, the direct injection fuel nozzle is suspended from a fuel rail in a fashion that avoids direct metal-to-metal contact between the injector and the engine block. The direct injection nozzle may also be connected to the fuel rail by a pair of spaced-apart seals which equalize the longitudinal pressure on the nozzle during operation. Enlarged diameter fuel reservoirs and/or a restricted orifice may be provided fluidly in series between the fuel pump and the direct injection nozzle in order to attenuate noise resulting from fuel pump pulsation.
