Detroit Diesel Reaches SCR Testing Milestone

Posted on November 8, 2008

Detroit Diesel Corp. announced that it has surpassed seven million miles of demonstrated testing on its BlueTec Selective Catalytic Reduction (SCR) technology. BlueTec SCR, used through a range of Mercedes-Benz automobiles and commercial vehicles, was selected by Detroit Diesel in 2005 to meet the upcoming EPA 2010 emissions standards for heavy-duty trucks.

¡§We started our engineering development and validation activities several years ago to optimize BlueTec SCR for the 2010 North American market,¡¨ said David Siler, director of marketing, Detroit Diesel Corp. ¡§We are excited about how successful we¡¦ve been in our validation program and we feel our customers will benefit from this positive experience.¡¨

BlueTec SCR will incorporate enhanced performance of Detroit Diesel¡¦s recently introduced DD15 and DD13 engines, the ACRS common rail fuel system, a diesel particulate filter already in use today, as well as a new SCR NOx aftertreatment system that utilizes diesel exhaust fluid (DEF), commonly known as urea. Since adapting the technology in early 2005, Daimler has delivered more than 200,000 trucks and buses around the world utilizing BlueTec SCR.

The company said its validation testing is not yet complete. Its reliability test vehicle fleet is expanding monthly and will continue to log millions of miles prior to production launch in January 2010. Detroit Diesel has also conducted several rounds of vehicle validation testing under extreme operating and environmental conditions, such as below-zero winter conditions in northern climates, as well as high temperatures in the desert regions of Arizona, Nevada and California.
