Pierce Manufacturing on Schedule with Launch of 2010 EPA Compliant Engines



APPLETON, Wis. (December 14, 2009) — Pierce Manufacturing, an Oshkosh Corporation (NYSE:OSK) company, announced that testing for its new 2010 EPA compliant engines is on schedule. In recently completed validations on Pierce fire apparatus, the Detroit Diesel DD13™ engine has demonstrated up to five (5) percent better fuel economy than previous engines, while delivering up to 500 horsepower and 1650 ft-lbs of torque on-demand. This Detroit Diesel DD13 engine is only available through Pierce Manufacturing, and can be purchased on selected custom chassis vehicles later this year.

“It’s our mission to provide Pierce customers with safe, technologically advanced, reliable and environmentally friendly vehicles,” said Wilson Jones, Oshkosh Corporation executive vice president and president, Fire & Emergency. “We’re pleased to report that the DD13 engine has hit every benchmark set by our product development and validation testing team. This engine is designed to reduce emissions to near zero without compromising performance.”

The DD13 is an advanced design that offers seamless integration of BlueTec®* selective catalytic reduction (SCR) technology that, according to the company’s test data, reduces nitrogen oxide (NOx) engine emissions to near zero without compromising power, fuel economy or performance.

“We drove a pre-production DD13-equipped pumper over the Rocky Mountains through 10,000 foot elevations without any problems,” said Ken Kamprath, Pierce Manufacturing chief engineer - research and development. “We also conducted an array of cooling system and reliability tests that included pulling a 40,000-pound trailer up the renowned Baker Grade on the Nevada/California border. The vehicle ran smoothly and performed exceptionally well under those extreme conditions.”

Pierce and Detroit Diesel have developed proprietary emissions components that will have virtually no impact to wheelbase, cab and compartment space, or options on the vast majority of apparatus.

“Our onsite wind tunnel testing and reliability testing in Death Valley confirm that the Pierce – Detroit Diesel collaboration for 2010 engine compliance will provide our customers with the performance and reliability they’ve come to expect from Pierce apparatus,” added Jones. “Moreover, in most applications the DD13 engine will have no impact on how they can configure a vehicle.”

Detroit Diesel parent company, Daimler, has manufactured more than 200,000 SCR diesel trucks in Europe and around the world. SCR is a proven technology that works by injecting diesel exhaust fluid (DEF), a simple solution of water and urea, into the exhaust stream. DEF works with the heat of the exhaust and a catalyst to convert NOx into nitrogen and water vapor – two harmless and natural components of air. Utilizing SCR to reduce emissions allows the engine to produce efficient power and torque.
