3.3.5 Injector Retaining Clip
The injector clip (refer to Figure 3-6) is typically supplied as part of the
injector assembly and provides the following functions:
•
Retains the injector to the rail prior to assembly to the engine.
•
Allows the rail assembly (including injectors) to be removed from the
manifold as a unit, enabling fuel to be retained in the rail. This also
applies if the rail is impacted and moved relative to its normal mounted
position.
•
Positions the injector during normal operation, preventing solid contact
with the manifold/head. Solid contact affects noise and heat transfer to
the injector, and possibly injector durability.
•
Provides a method for rotational orientation of the injector with respect
to the rail. This is especially important for the dual-spray injector
design to maintain spray proper targeting relative to the intake valves.
Note: The injector retaining clip is designed to engage the
encapsulation post and maintain rotational orientation of the injector in
the fuel rail socket.
