Detroit Diesel Corporation, a supplier of motorhome diesel engines, has
announced that it has surpassed seven million miles of demonstrated
testing on its BlueTec Selective Catalytic Reduction (SCR) technology.
BlueTec SCR will help the engines meet the upcoming stringent EPA 2010
emissions standards and represents the world’s latest in clean diesel
engine technology. BlueTec SCR will incorporate 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.
A reliability test vehicle fleet 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 temperatures above
120 degrees in the desert regions of Arizona , Nevada and California.
Nearly 100 percent of all big bore engines in production today for the
U.S. and Canada that will be manufactured after Jan. 1, 2010, will
utilize SCR technology.
