Pierce On Schedule With 2010 Engines

Pierce Manufacturing said testing for its new 2010 Environmental Protection Agency compliant engines is on schedule, and the Detroit Diesel DD13 demonstrated up to 5 percent better fuel economy than previous engines.

The DD13, which delivers up to 500 horsepower and 1650 foot pounds of torque on-demand, is only available through Pierce and can be purchased on selected custom chassis vehicles.

“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 of the company’s fire and emergency group, which includes Pierce. “We’re pleased to report that the DD13 engine has hit every benchmark set by our product development and validation testing team.”

The DD13 offers 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’s chief engineer for 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.”

Pierce and Detroit Diesel have developed proprietary emissions components that are expected to 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,” Jones said. “Moreover, in most applications the DD13 engine will have no impact on how they can configure a vehicle.”

Detroit Diesel’s 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.
