Detroit Diesel Engines with BlueTec Certified as Compliant with EPA 2010 Emissions Standard in the US

The US Environmental Protection Agency (EPA) has certified the entire family of heavy-duty diesel engines made by Detroit Diesel Corporation (DDC), a Daimler Company—DD13, DD15, and DD16 engines with SCR technology— as being in compliance with the EPA 2010 emissions standard, which took effect at the start of this year.

EPA 2010 is the world’s most stringent emissions standard. Daimler Trucks North America (DTNA) decided at an early stage in favor of the SCR technology because engines with this system are best equipped to meet the special emissions requirements for trucks in North America. The technology, which is used under the name BlueTec at Daimler Trucks, relies on selective catalytic reduction (SCR) to reduce emissions to near-zero levels.

In addition to satisfying the EPA 2010 emissions standards, the BlueTec-equipped DD13, DD15, and DD16 engines from Detroit Diesel also improve fuel efficiency and handling. Extensive testing has proved that these engines deliver fuel savings of up to 5% compared to the engines from 2007.

The engine- and vehicle-development engineers at DTNA collaborated on this technology, applying what they learned from Daimler Trucks’ experience in Europe and adapting this knowledge to the specific requirements on the trucks market in North America. Since the introduction of SCR technology in 2005, more than 260,000 trucks and buses with BlueTec have hit the road in Europe.
