Abstract
Official abstract text for this publication.
Attaching a fuel injector to a common rail may utilize a fuel injector and an integral tab that has a solid head portion from which a first flexible prong and a second flexible prong protrude and define a gap therebetween. A fuel injector cup may define a notch through which the first prong and the second prong reside to secure the fuel injector to the fuel injector cup, which is attached to the rail. A first prong interior straight wall surface and a second prong interior straight wall surface may face the gap and be parallel. The prongs may define entry contact surfaces and exit contact surfaces that meet at prescribed angles to aid in insertion and hinder retraction of the injector tab from the injector cup. The tab defines a solid head portion below the gap that resides in the notch.
First claim
