Detroit Diesel Corp. announced its BlueTec emissions technology completed 25 million miles of testing ahead of schedule, and that by its rollout on Jan. 1, 2010, the Detroit Diesel BlueTec technology will surpass 28 million miles of testing.

“We are pleased to have taken full advantage of our early choice of SCR as the best technology for our customers for 2010,” says David Siler, director of marketing for Detroit Diesel. “The 2010 BlueTec technology will be one of the most extensively tested emissions technology systems in our company’s history, and having this decade of experience has allowed Detroit Diesel and Daimler Trucks North America to not only have an extended period of time for system design and performance refinement, but also to gain significant testing and validation experience. The early commitment to the technology allowed us to finalize our production-intent designs early and to conclusively demonstrate the performance, durability and effectiveness of our BlueTec technology on production designs over the extended lifecycle demands of our customers.”

BlueTec will incorporate the performance of Detroit Diesel’s recently introduced DD15, DD13and DD16 big bore engines, as well as the ACRS fuel system and an integrated engine-compression brake. Detroit Diesel says its BlueTec technology includes a 1-Box packaging design optimized for low back-pressure and an all-new diesel particulate filter (DPF) material. The BlueTec aftertreatment system will utilize diesel exhaust fluid (DEF) and has been fully optimized for low emissions and high fuel economy, according to the company.

“We are meeting our program goals for performance and emissions, fuel economy, durability and reliability,” says Rakesh Aneja, EPA 2010 program manager for Detroit Diesel. “Our current projections are showing up to a 5 percent diesel fuel economy improvement, and up to a 3 percent net improvement with our BlueTec-equipped engines compared to today’s engines. In cooperation with our vehicle colleagues at Daimler Trucks North America, we have had the opportunity to test our 2010 BlueTec system under diverse ambient and environmental conditions, operating conditions and routes. The results of our validation testing meet our expectations and offer a shift from fuel penalties to fuel economies for our customers in 2010, with simultaneous reduction of emissions and CO2, compared to today’s EGR-only vehicles.”

Daimler Trucks says that since adapting the technology in early 2005, it has delivered more than 200,000 trucks and buses around the world utilizing BlueTec.
