PACCAR to Use SCR and EGR for 2010 Engine NOx Requirements

31 January 2008

PACCAR, manufacturer of light-, medium- and heavy-duty trucks under the Kenworth, Peterbilt and DAF nameplates, stated in its Q4 2007 Earnings Statement that it will use selective catalytic reduction (SCR) in combination with exhaust gas recirculation (EGR) in its PACCAR engines for Kenworth and Peterbilt to meet the NO_x requirements of the 2010 EPA diesel engine emissions regulations.

Starting in 2010, allowable NO_x emissions will be reduced by more than 80% from the 2007 standard. PACCAR trucks have been using SCR emissions systems in Europe for several years.

The company said that it is working with SCR distributors to ensure a nationwide infrastructure is in place to support the SCR aftertreatment systems with urea.
