NON-GENUINE AND

QUALITY A LERT
In recent years, electronic engine
controls have been instrumental
in aiding engine manufacturers in
meeting the stringent emission
requirements of the U.S.
Environmental Protection Agency
(U.S. EPA ) and the Calif ornia Air
Resources Board (CARB) and
also in meeting the ever-increasing
performance demands of the customer.
Maintenance procedures are to
be followed in order to continue
satisfactory performance and
durability and to ensure coverage of
the engine under th e manufacturer's
warranty. Many of th e se maintenance
procedures also ensure that the engine
continues to comply with app licable
emissions standards. The U.S.
EPA specifically defines a n engin e's
“useful emission life” — currently
established as 290 ,0 00 miles (464,000
kilometers) for on-highway engines.
Proper maintenance procedures, using
specific compon ents engineered to
comply with emissions regulations,
may be p erform ed by an authorized
Detroit Diesel distributor or dealer,
an in depen dent outlet or the operator
or owner. The owner is responsible
for d eterm in ing the suitability of
components to maintain emissions
compliance during the engine's useful
emission life.
Electronic controls and components
have significantly increased in
sophistication, but the fundamen tal
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). Th e proper functioning of the
EUI is absolutely paramount if the
benefits of electronic controls are to be
realized. Detroit Diesel Corporation
has built o ver 650,000 engines with
electronic unit injectors — more than
anyone else in the business.
