Does anyone know when to buy such parts? From the journal elektronikpraxis I have this article:www.elektronikpraxis.vogel.de/…/strategieunternehmensf… The cost-effective apparatus can be installed in any car, even gasoline could benefit from it, write the physicists around Rongjia Tao from Temple University in Philadelphia (US state Pennsylvania) . A suitably equipped Mercedes-Benz 300D increased its reach in a six month practical test of 13.6 to 16.2 km/l on the US highway – an increase of 18.75%. The fuel consumption thus decreased from 7.4 to 6.2 l/100 km. In the city the fuel yield did not increase quite as much, but still by 12 to 15%, reports the physicists. The small unit consists of a few centimeters long cylinder, which is installed before the injection nozzle. Inside it there is a strong electric field, the flowing fuel is charged electrically. The field requires very little Stro m. The repulsive effect of the electric charge makes the fuel thinner, and considerably smaller droplets are injected into the engine, which burn much more efficiently and cleaner, the researchers explain. Accordingly, the engine power of the diesel car in the laboratory increased by 20.4% during a solid spray.
