Calling it “a reengagement” with the industry, Detroit Diesel Corp. has announced it will supply American bus and coach manufacturers with engines that meet the new U.S. Environmental Protection Agency (EPA) diesel engine emissions requirements taking effect in January.
Like the engines Detroit Diesel is building for its parent company, Daimler Trucks of North America (DTNA), the bus and coach powerplants will employ selective catalytic reduction (SCR) to deliver emissions levels that meet the new standards.
Currently Detroit Diesel is in the process of obtaining 2010 EPA certification for the proprietary DD13, DD15 and the new DD16 heavy-duty engines it builds for the DTNA truck brands Freightliner and Western Star. All three engines will now also be offered to bus and coach builders, the company announced in a press release.
“Detroit Diesel had been an important supplier to MCI for many years, and we look forward to the return of their leadership, technological advances and commitment to this market for decades to come,” said Terry Loewen, powertrain systems manager for Motor Coach Industries.
Founded originally as a division of General Motors Corp., Detroit Diesel has a long history of supplying diesels for buses that stretches back to the 1950s when GM first developed a dominate position in the transit bus market.
