摘要： A fuel injector assembly for use with an engine block of a direct injection engine. The fuel injector assembly includes an elongated tubular fuel rail which is fluidly connected to a high pressure fuel source. At least two fuel cups are attached to and extend downwardly from the fuel rail and each fuel cup is adapted to receive one fuel injector. First fasteners attach a bracket to the engine block while second fasteners attach the bracket to the fuel rail. These second fasteners, furthermore, are positioned so that the second fasteners are coplanar with a plane extending through a longitudinal axis of each fuel injector.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A fuel system for a direct injection internal combustion engine having a fuel rail and at least one annular cup secured to the fuel rail so that fuel from the fuel rail flows into the cup. A direct injection fuel injector has a portion axially insertable into the fuel cup to a connected position. A recessed channel on the fuel injector registers with a slot in the annular cup when in the connected position so that a U-shaped clip insertable into the cup slots and the fuel injector channels secures the fuel injector and cup together against axial movement.
