NASA Tests Devices to Increase Truck Fuel Efficiency

摘要

Saving the nation $10 billion annually in diesel fuel costs may be possible in a few years, thanks to new devices developed at Lawrence Livermore National Laboratory (LLNL) and now being tested at NASA's Ames Research Center in California.rnLLNL has teamed with Navistar (Warrenville, IL), NASA Ames, the U.S. Air Force, and industry, to develop and test devices for reducing the aerodynamic drag of tractor-trailers. The average fuel mileage of a tractor-trailer is six miles per gallon. A two percent reduction in the aerodynamic drag of tractor-trailers translates into 285 million gallons of diesel fuel saved per year.
