Detroit Diesel announced it has surpassed 7 million miles of demonstrated testing on its BlueTec Selective Catalytic Reduction (SCR) technology.


Daimler's BlueTec SCR was selected by Detroit Diesel in 2005 to meet the upcoming stringent 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 for Detroit Diesel. "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 already proven 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.

Detroit Diesel's extensive validation testing isn't 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 that may be experienced by the end-user, such as below-zero winter conditions in northern climates, as well as temperatures above 120 degrees in the desert regions of Arizona, Nevada and California.

Since adapting the technology in early 2005, Daimler has delivered more than 200,000 trucks and buses around the world utilizing BlueTec SCR. Daimler's BlueTec System is modular and will be adaptable for use in vocational applications, buses and RVs, as well as hybrids and biodiesel powered trucks.
