Diesel Diet

摘要

California-based Save the World Air, Inc., says its Elektra fuel pump add-on can improve a big-rig truck's highway fuel economy by as much as 10 percent. That could cull a trailer truck's diesel intake by more than 2,000 gallons a year, says Joe Dell, the company's vice president for marketing, saving a typical 1,000-truck fleet two million gallons. The thermos-size device is based on technology from Temple University that thins fuel with an electric field, creating smaller droplets that burn more thoroughly, which yields more energy and pumps less unburned fuel from the exhaust pipe. The company will test a refined, smaller version of the device this year and could have a model ready for diesel cars by 2011.
