Detroit Diesel submits EPA applications

Detroit Diesel Corp. (DDC) has confirmed submitting applications to EPA for emissions certification of its Series 60 diesel engines. These initial emission-certification applications will cover 20 of the currently available Series 60 ratings. All will be fully compliant to the October 2002 emission requirements, said DDC, and additional ratings will be submitted for certification in the future. By October 1, DDC will have accumulated approximately eight-million test miles on its fleet of test vehicles equipped with October 2002 prototype engines. Also by October 1, 27 different fleets will have engines in operation, in addition to the factory-owned test units. "Of course, we are well aware of the questions some truckers have about the Series 50 and 60 engines equipped with exhaust gas recirculation (EGR)," said John Morelli, vp of the Series 60 2002 engine program. "For those who may not be aware of it, EGR has been used on the Series 50 since 2000. We have over 2,500 units in operation and I want to reassure the trucking industry that these Series 60 and 50 engines are excellent products. Morelli said that now that DDC has eight-million test miles under its belt, it is confident the new engines will continue to meet customers' expectations. He added that the warranty on 2002 engines will remain exactly the same, as will the maintenance schedule.
