Diesel Cleans Up
(Business 2.0 Magazine) -- With gas prices still high, it's a great time to sell drivers on the only widely available alternative. Diesel cars are 20 to 30 percent more fuel-efficient than regular autos. Trouble is, they spew much more nitrogen oxide, the main cause of smog.
But now DaimlerChrysler (Charts) has found a chemical to clean up diesel's act - and it's as near as your next bathroom break. Urea, a waste product the body excretes in urine, neutralizes nitrogen oxide. The auto giant's AdBlue system, already used in European trucks and featured in a prototype version of the Mercedes GL-320, sprays a fine mist of odorless urea on diesel exhausts.
That puts DaimlerChrysler in the driver's seat of the U.S. diesel car market, which J.D. Power predicts will quadruple by 2015 - especially since tough new smog standards kick in next year.click here.
