DPF Could Save Fuel in Heavy-Duty Pickups

GM and Oak Ridge National Laboratory are jointly developing new emissions-cleaning technology that promises better fuel economy for future heavy-duty diesel truck buyers, according to a presentation given during the U.S. Department of Energy's 2011 Merit Review in Washington, D.C.

In 2007, the EPA cracked down on the amount of soot diesel engines could produce, cutting allowable emissions by 90 percent from 2006 levels.
