Abstract
Various embodiments include a fuel injection assembly comprising: a fuel injector; an injector cup comprising a cylindrical body with a cavity at the lower end to receive a fuel inlet port of the injector; a holding element for securing the injector to the cup; a spring clip; and a first opening formed in a peripheral wall of the cup for receiving the holding element. The holding element comprises a U-shaped body with two parallel arms engaging opposite sides of an annular groove in the injector to secure the injector in the cup. When inserted in the cup, the free ends of the two arms project from the cup, and include adjacent the free ends a retention arrangement engageable by the spring clip. The spring clip comprises a depending leg engageable in a corresponding receiving part on the injector to locate the angular position of the injector relative to the cup.
