Detroit Diesel Corp. (DDC) announced it will deploy parent firm Daimler's BlueTec system, which uses selective catalytic reduction (SCR), as its “chosen technology to meet the upcoming stringent EPA 2010 standards for heavy-duty trucks.”

DDC said BlueTec represents the world's latest in clean diesel engine advances and will provide improved performance with Detroit Diesel's recently introduced DD15 engine as well as its future family of engines, including the DD13 and DD16. All of the 2010 engines will combine with the amplified common rail system (ACRS) and a diesel particulate filter with a new SCR exhaust emissions aftertreatment system.

“I'm happy to announce that we will be utilizing BlueTec technology for our Detroit Diesel engines beginning in 2010,” said Chris Patterson, president and CEO of Daimler Trucks North America (DTNA). “The technology is clearly the best choice for our customers. BlueTec is the only means of meeting the stringent 0.2 g/kWh NOx standard for heavy-duty diesel engines in 2010, while actually reducing diesel fuel consumption in comparison with the technology used in 2007 engines.”

According to the company, BlueTec “compels no compromise in performance or fuel consumption, essential to today's operators beset by skyrocketing fuel prices, while striving to attract and retain the best of a very constrained driver pool.”

Detroit Diesel's BlueTec system uses automotive-grade urea, also known as diesel exhaust fluid (DEF) or, in Europe, AdBlue. It works with the heat of the exhaust and a catalyst to convert NOx emissions into harmless levels of pure nitrogen and water vapor, said DDC.

Detroit Diesel worked with other Daimler companies to develop and build the North American version of the technology to meet EPA 2010 standards. According to DDC, their system with a 20-gal. DEF tank requires refills only about every 5,000 to 6,000 miles under typical highway duty cycles.
