Electronic controls and components
have significantly increased in sophistica-
tion, but the fundamental objective
remains the same – precise timing and
delivery of fuel. The very heart of the
Detroit Diesel Electronic Controls 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 500,000
engines with electronic unit injectors –
more than anyone else in the business.
Detroit Diesel cautions that the indiscrim-
inate rebuilding of precision compo-
nents, without the
specifications, specialized equipment,
and knowledge of the electronic operat-
ing system, will jeopardize performance
or lead to more serious problems, and
can take the engine outside of compli-
ance with EPA or California 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.
benefit of 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 specifi-
cations may result in early wear out or
engine failure.
