REDFORD, Mich. –Detroit Diesel says its selective catalytic reduction (SCR) system, dubbed BlueTec, has reached seven million miles in North American validation testing.
“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. “We are excited about how successful we’ve been in our validation program and we feel our customers will benefit from this positive experience.”
Detroit Diesel’s DD15 and DD13 engines will use BlueTec technology to meet EPA2010 emission standards. A common rail fuel system, diesel particulate filter and exhaust gas recirculation will also be employed. SCR requires the use of diesel exhaust fluid (DEF), which is dosed into the exhaust stream to create a chemical reaction that reduces NOx into harmless water and nitrogen.
The company says it is continuing its validation testing and expanding its test fleet monthly. It has also conducted extreme weather testing in sub-zero temperatures as well as in the Nevada desert.
“We have leveraged our relationship with Daimler Trucks North America by jointly conducting our design, packaging and validation testing activities,” said Rakesh Aneja, Detroit Diesel’s 2010 program manager.
“This ensures that the vehicle is optimized as an integrated system with respect to lifecycle cost including fuel economy, durability and reliability.”
In addition to racking up more than seven million miles of testing in North America, Detroit Diesel’s parent company Daimler has delivered more than 200,000 vehicles with SCR around the world. •
