Paccar announced that it will join Detroit Diesel, Volvo and Mack in the use of selective catalytic reduction as an element in its engine platform to meet 2010 Environmental Protection Agency standards for NOx emissions.

In the Paccar platform, SCR will be used in concert with exhaust gas recirculation, the primary emissions component of most 2002 and 2007 heavy-duty engine technologies.

“The combination of SCR and EGR will provide Paccar customers a highly efficient solution to meet the rigorous 2010 emission requirements,” says Craig Brewster, Paccar assistant vice president. Brewster says the company’s vehicles have operated SCR emissions systems in Europe successfully for years.

“Paccar is working with SCR distributors to ensure a nationwide infrastructure is in place to serve our customers,” Brewster says. The infrastructure is needed to supply urea for the engines.

Current work on Paccar’s $400 million engine production facility in Columbia, Miss., is expected to wrap up in late 2009. The facility will produce the 12.9-liter and 9.2-liter MX and PR engines, respectively, for Kenworth and Peterbilt tractors, launching Paccar heavy-duty engines in the North American market.

“Paccar premium-quality engines will be offered to our customers to complement the engines available from our existing suppliers in North America in 2010,” Brewster says.
