INTRODUCTION
Electronic controls and components
have significantly increased in
sophistication, but the fundamental
objective remains the same — precise
timing and delivery of fuel. The very
heart of the Detroit Diesel Electronic
®
Controls (DDEC ) is the electronic
unit injector (EUI). The proper
functioning of the EUI is absolutely
paramount if the benefits of electronic
controls are to be realized. Detroit
Diesel Corporation has built over
650,000 engines with electronic unit
injectors — more than anyone else in
the business.
Detroit Diesel cautions that the
indiscriminate rebuilding of precision
components, without the benefit of
specifications, specialized equipment,
and knowledge of the electronic
operating system, will jeopardize
performance or lead to more serious
problems, and can take the engine
outside of compliance with U.S. EPA
or CARB emissions standards.
There are other components in
an engine, such as turbocharger,
camshaft, piston, etc., which
are specifically designed and
manufactured to exacting standards
for emissions compliance. It is
important that these components, if
replaced, modified or substituted, can
be verified to ensure that the engine
remains in compliance with emissions
standards. The use of inadequately
engineered, manufactured or tested

components in repair or rebuild of
the engine may be in violation of the
federal Clean Air Act and applicable
U.S. EPA or CARB regulations.
Furthermore, modern engines exhibit
operating parameters which require
the use of proper fluids, such as
fuel, coolant and lubricating oil, to
maintain long engine life. The use of
fluids that do not meet Detroit Diesel
Corporation specifications may result
in early wear out or engine failure.
