Introduction Multec 3.5 Fuel Injector Application Manual
1-2 Delphi Energy and Chassis Systems
Revision: 11/05-01
The objectives of this document are to help:
• Obtain maximum value and optimum performance from the Multec
3.5 Fuel Injector
• Integrate the Multec 3.5 Fuel Injector within the engine control system
(hardware and software)
• Protect the Multec 3.5 Fuel Injector from damage caused by improper
usage, mounting, handling, or installation
• Prevent testing errors that might result in an inaccurate evaluation of
Multec 3.5 Fuel Injector performance
• Prevent calibration errors that may interfere with the proper operation
of the Multec 3.5 Fuel Injector
To accomplish these objectives, this manual provides the following:
• A description of the components and features of the Multec 3.5 Fuel
Injector
• A description of the process used to determine the requirements
needed to achieve the following objectives:
− Accurate fuel flow requirements
− Proper injector spray
− Proper injector spray targeting
• A description of the options for packaging and mounting, as well as the
optional features available to meet underhood packaging, serviceability
and diagnostic requirements
• Calibration and testing guidelines
• A checklist of interface details required for Delphi to ensure that the
proper fuel injector selection is made to meet customer requirements.
The fuel injector should be specified based upon the constraints/
demands of the engine control module (engine controller and software)
and the chassis fuel supply subsystem (fuel rail, fuel pressure regulator,
fuel pump, fuel filter and supply lines).
