PORTLAND, OR - Recently completing more than 25 million miles of testing with its BlueTec emissions control system, Detroit Diesel Corporation has filed applications with the U.S. Environmental Protection Agency (EPA) and the California Air Resource Board (CARB) for 2010 certification of Detroit Diesel DD13 and DD15 engines with BlueTec emissions control systems. The company will apply for DD16 certification next month.

The applications submitted by Detroit Diesel provide the EPA and CARB with test results and documentation required to validate that the engine systems are in compliance with new 2010 emissions standards set by the EPA in December 2000 and CARB in October 2001. The U.S. standards for 2010 are the most stringent emissions standards in the world, and reduce two of the most detrimental pollutants, NOx and particulate matter, to near-zero levels at the tailpipe.

"The submission of our 2010 certification applications, based on successful completion of our emissions and OBD certification testing, is a key program milestone for us. We have millions of test miles under our belt, including 'real world' freight hauling experience in customer trucks as well as our own testing in extreme ambient conditions and diverse operating conditions. We are pleased with test results confirming that our Detroit Diesel engines with BlueTec consistently meet the 2010 emissions standards," said Rakesh Aneja, 2010 program manager, Detroit Diesel. "In addition to being good for the environment, BlueTec allows the performance of the engine to be optimized, thereby
meeting customers' need for fuel efficiency, drivability, reliability, simplicity, and convenience. We are satisfied with the readiness of our engine and after-treatment system for production launch - in fact, pre-production of our 2010 trucks and engines is already underway. We remain excited at the prospect of offering a paradigm-changing product
to our customers."

"After a decade of investment in both resources and funding to design, develop, integrate and test both engine and emissions control technologies, the early application for certification of our most popular engines brings tremendous satisfaction to the team at Detroit Diesel and Daimler Trucks North America," said David Siler, director of marketing, Detroit Diesel. "We're pleased to deliver on our commitment to build highly efficient engines and emissions systems that are among the cleanest in the world."

Detroit Diesel chose selective catalytic reduction (SCR) as the primary technology to meet the EPA 2010 emissions regulations. SCR has proven to be an effective means to reduce NOx emissions and the only proven technology for meeting the EPA 2010 standards as measured at the tailpipe.
