Detroit Diesel's DD13, DD15, and DD16 heavy-duty engines have received 2010 EPA emissions certification. The commercial truck engines are fitted with the BlueTec-branded selective catalytic reduction emissions control system and are currently in production at Detroit Diesel's Redford, Michigan, facility. Before receiving official certification, the BlueTec-equipped engines had accumulated more than 28 million equivalent miles of testing, including 1.5 million miles of real-world freight hauling assessment. The revised diesel engines are available with numerous Freightliner and Western Star applications.
"In addition to our rigorous internal testing, the extra time allowed for completion of more than one and a half million miles of real world testing under North American freight hauling conditions as part of our customer demonstration program before BlueTec is being introduced to the commercial market," said David Hames, general manager of marketing and strategy for Daimler Trucks North America. "The technology offers a paradigm shift from fuel penalties to fuel economies with simultaneous reduction of emissions and CO2, compared to today's EGR-only vehicles."
Detroit Diesel is a subsidiary of Daimler Trucks North America.
Current emissions standards are pegged at:
- Particulate matter (PM) -- 0.01 grams/brake horsepower hour (g/bhp-hr)
- Nitrogen oxide (NOx) -- 0.2 g/bhp-hr
- Non-methane hydrocarbons (NMHC) -- 0.14 g/bhp-hr
