DDC applies for Series 60 engine certification

Detroit Diesel Corp (DDC) has submitted applications to the Environmental Protection Agency (EPA) for emissions certification of its Series 60 diesel engines. These initial emission certification applications will cover 20 of the currently available Series 60 engine ratings. All will be fully compliant with October 2002 emission requirements. Additional ratings will be submitted for certification in the coming months.

By October 1, DDC will have accumulated about 8 million test miles on its fleet of test vehicles equipped with October 2002 prototype engines. Also by that date, 27 different fleets will have engines in operation, in addition to the factory-owned test units.

The warranty on these engines remains exactly the same. There is no difference in the recommended oil change intervals because the soot concerns have not materialized. The required-maintenance schedule has not changed, and no additional parts are subjected to maintenance requirements.

DDC says the piston ring is the key to long engine life, and ring face wear is 78% lower on the EGR engines when compared with the firm's current engines. Also, weight of the Series 60 has been reduced by 25 pounds.
