Detroit Diesel announced last week that it plans to use Daimler's BlueTec System to meet the upcoming stringent EPA 2010 standards for heavy-duty trucks.


BlueTec represents the world's latest in clean diesel engine technology and will incorporate enhanced performance of Detroit Diesel's recently introduced DD15 engine and its future family of engines, including the DD13 and DD16, the already proven ACRS common rail fuel system and diesel particulate filter, as well as a new Selective
Catalytic Reduction (SCR) exhaust emissions aftertreatment system.

"BlueTec is the only means of meeting the stringent 0.2 g/kwh NOx standard for heavy-duty diesel engines, in 2010 while actually reducing diesel fuel consumption in comparison with the technology used in 2007 engines," said Chris Patterson, president and CEO of Daimler Trucks North America.

Company officials say the BlueTec System with SCR technology is projected to increase fuel efficiency by about 3 to 5 percent.

Detroit Diesel's BlueTec System uses DEF, (diesel exhaust fluid, also known as urea), a common nitrogen-containing compound. It works with the heat of the exhaust and a catalyst to convert NOx emissions into harmless levels of pure nitrogen and water vapor - two natural components of the air we breathe.

Detroit Diesel worked with other Daimler companies to develop and build the North American version of the proven technology to meet EPA 2010 standards. Built upon the
experience of its European counterparts, SCR is proven technology that requires DEF refilling only about every 5,000 to 6,000 miles per 20-gallon tank under typical highway duty cycles.
