56 Other significant component drivers
(external noise, external corrosion) specify
driver and requirement
57 Injector tip to interface with cylinder head
58 Component assembly best practices
evaluated (engine and vehicle plants).
59 Max injector prime pulse and vehicle
assembly prime analyzed with respect to
engine hydrolock
60 Use of proper seal ring lubricants at engine
assembly verified.

Handling Recommendations
62 Injector service procedure set-up according
to Delphi guidelines prior to SOP
Note: Final injector selection requires verification by customer for emissions and driveability
compliance. This should include limit flow distribution and injector tip leakage hardware.
Seq: Sequential fire; SDF: Simultaneous Double Fire; ASDF: Alternating Simultaneous
Double Fire; SSF: Simultaneous Single Fire; SFC: Specific Fuel Consumption; MAP:
Manifold Absolute Pressure; BLM: Block Learn Multiplier
If the injector lower seal is located in cylinder head, this will expose the injector to
higher than normal temperatures.
