GREENSBORO, NC—Volvo North America has chosen SCR for its 2010 emissions technology solution. SCR is an after treatment technology that involves injecting a water-based solution containing urea into the hot exhaust stream of an engine. The urea, in conjunction with a catalyst in the exhaust after treatment system, breaks down the NOx into harmless nitrogen and water vapor. Urea is an organic nitrogen-containing compound commonly used in agriculture as a fertilizer and is classified by the Environmental Protection Agency as a non-hazardous substance. Volvo’s technology solution for 2010 will also include a diesel particulate filter (DPF) and exhaust gas recirculation (EGR). Volvo has employed EGR on its engines in North America since late-2002, while DPFs will be used starting in 2007 on Volvo’s new family of diesel engines. Volvo also draws upon the Volvo Group’s experience with SCR in Europe, where the technology is used to meet the Euro 4 emissions regulations. That experience includes more than 23 million test miles, as well as production for regular use by customers beginning this year. Volvo Trucks North America has also had customer field tests of SCR-equipped trucks operating in the United States since 2003. Volvo Trucks North America assembles its Volvo VT, VN, and VHD trucks in the United States, at the ISO14001 and ISO9001 certified New River Valley Plant in Dublin, Va. Volvo engines for North America are assembled in Hagerstown, Md.
