General Information
The engine is an electronically controlled, mechanically actuated unit injector diesel engine.
The electronic unit injector (EUI) eliminates many of the mechanical components of a mechanical unit injector. The EUI also provides increased control of timing. The timing advance is achieved by the precise control of the injector firing time. Engine rpm is controlled by adjusting the firing duration. A speed/timing sensor provides information to the electronic control module for detection of the cylinder position and the engine rpm.
The engine has built-in diagnostics in order to ensure that the components are operating properly. An electronic service tool can be used to read diagnostics. Refer to the Troubleshooting manual for more information.
