Volvo Trucks North America's D11 and D13 engines have been certified by the US Environmental Protection Agency and the California Air Resources Board as meeting upcoming 2010 diesel emissions standards.
The company says it is the first truck manufacturer to have its heavy-duty diesel engines certified for 2010 by both EPA and CARB. These engines have been fully certified to meet EPA's standards without the use of emissions credits.
Volvo Trucks' emissions technology for EPA2010 does more than cut emissions of nitrogen oxides (NOx) and particulate matter to near-zero levels. Using selective catalytic reduction (SCR) to reduce NOx, Volvo improved fuel economy and reduced emissions of the greenhouse gas carbon dioxide. This fights global warming and reduces dependence on imported petroleum. SCR also helps eliminate active regenerations of the diesel particulate filter (DPF).
All heavy-duty diesel truck engines produced after January 1, 2010 must meet the new standards. Volvo has experience with SCR technology, having accumulated 5 million miles with 50 test vehicles in customer field-test fleets in North America. Volvo also has billions of miles of real-world experience with SCR in other markets. The new SCR system was added to the Volvo engine platform, which has been used in North America since 2007.
