Detroit Diesel Corporation has surpassed seven million miles of demonstrated testing on its BlueTec Selective Catalytic Reduction (SCR) technology. BlueTec SCR was selected by Detroit Diesel in 2005 to meet the upcoming stringent EPA 2010 emissions standards for heavy-duty trucks.
BlueTec SCR will incorporate performance of Detroit Diesel's recently introduced DD15 and DD13 engines, the ACRS common rail fuel system, a diesel particulate filter already in use, as well as a new SCR NOx aftertreatment system that uses 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. The firm 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.
