Tip Location
•
To prevent fuel collection at the injector tip and surrounding port
surfaces do not recess the injector tip from the airflow.
4.2.1.1 Limits on Injector Position
The fuel injector should be located to meet the following requirements
when analyzed at worst-case dimensional conditions for rail injector and
engine:
•
No injector interference when seated into the manifold / head.
•
With the injector clip removed, no loss of fuel seal with rail socket.

4.2.2 Orienting the Injector
Injector spray targeting and combustion quality are interrelated and must
be evaluated in the specific application (refer to Section 3.8 for
information on injector targeting, placement and cone angle). An
orientation tab on the injector solenoid engages the injector clip and
allows the injector to be oriented rotationally relative the fuel rail. The
fuel rail then supplies the specific feature for orienting the injector clip.
See Figure 3-6.
