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: In some examples, a clip prevents relative rotation between a fuel injector and an injector cup of a fuel rail. For instance, the fuel injector may be rotated following insertion into the injector cup to prevent removal of the fuel injector. The clip includes a clip body having a pair of arms extending from the clip body with an opening between the arms for receiving the fuel injector. A tab extends from the clip body into the opening for engaging a first alignment slot in the injector cup and a second alignment slot in the fuel injector when the clip is installed on the fuel injector. Following installation of the clip on the fuel injector, the tab is disposed in the first and second alignment slots to prevent relative rotation between the fuel injector and the injector cup.
