The Mechanical Electronic Unit Injector (MEUI) fuel
system is used on this engine. The MEUI fuel system
eliminates many of the mechanical components
that are used in a pump and lines. The electronic
control and mechanical actuation provides increased
control of the timing and increased control of the fuel
injection pre ssure. The timing advance is achieved
by precise control of the unit injector timing. Engine
speed is controlled by adjusting the injection duration.
A special speed-timing wheel provides information to
the Electronic Control Module (ECM) for detection of
cylinder position and engine speed.
The engine has built-in diagnostics in order to ensure
that all of the components are operating properly. In
the event of a system component failure, the operator
will be alerted to the condition via the diagnostic
lamp that is located on the c on trol pa ne l. Ca terp illa r
Electronic Technician (ET) can be used to read the
numerical code of the faulty component or condition.
Intermittent faults are also logged and stored in
memory.
