Paccar Inc. said it will use selective catalytic reduction technology, in combination with exhaust gas recirculation, in its Paccar engines for Kenworth and Peterbilt trucks to meet to meet 2010 engine requirements.

The technologies will meet the 2010 Environmental Protection Agency standard for nitrogen oxides requirements of the EPA diesel engine emissions regulations, Paccar said in its earnings statement released Tuesday.

“The combination of SCR and EGR will provide Paccar customers a highly efficient solution to meet the rigorous 2010 emission requirements,” said Craig Brewster, the truck maker’s assistant vice president.

Paccar vehicles “have successfully operated SCR emission systems in Europe for several years,” he said.

Starting in 2010, allowable NOx emissions will be reduced by more than 80% from the 2007 standard.

“Paccar is working with SCR distributors to ensure a nationwide infrastructure is in place to serve our customers,” Brewster said. “Paccar premium-quality engines will be offered to our customers to complement the engines available from our existing suppliers in North America in 2010.”

Paccar is the parent company of U.S. truck makers Kenworth Truck Co. and Peterbilt Motors Co. and Europe-based DAF Trucks.
