DETROIT - Detroit Diesel, the engine manufacturer that belongs to Daimler Trucks North America (DTNA), has subjected BlueTec SCR technology in trucks to tests totaling 25 million miles. By the time SCR (selective catalytic reduction) technology is introduced in January 2010, the test vehicles will have been tested for a total of 28 million miles. This will make SCR technology one of the most thoroughly tested exhaust technologies in the United States as well.

After being extensively tested over a total distance of 25 million miles, SCR technology, which has been established in Europe since 2005, is now ready for use in the NAFTA market. Detroit Diesel engines with SCR technology will be introduced on January 1, 2010, when the U.S. emissions standard EPA10 takes effect.

BlueTec stands for Daimler's commitment to mastering today's ecological challenges while also ensuring exemplary performance and savings in terms of fuel consumption. Since the launch of this technology in the spring of 2005, Daimler Trucks has delivered more than 237,000 trucks and buses with BlueTec technology to customers around the world.

The North American version of BlueTec will be used in the DD13, DD15 and DD16 engines recently introduced by Detroit Diesel.

The most recent studies show that the benefits of SCR are widely recognized in the truck sector in North America. As soon as the customers investigate the technology and learn all the facts, SCR becomes their first-choice technology for staying competitive under EPA 2010.

Nearly 100 percent of all big diesel engines for the U.S. and Canada produced after January 1, 2010, will be equipped with SCR technology. The BlueTec technology used for Detroit Diesel engines features a modular design and is suitable for road use and various sector-typical applications.
