New Electric Field Device Reduces Car Fuel Consumption by 20%


Professor Rongija Tao, from Temple University, invented a device that, applied to the vehicle’s fuel line, near the injectors, creates an electric field that reduces the fuel’s viscosity, so that smaller droplets are injected into the engine, leading to better combustion and increased fuel efficiency as much as 20%.

Rongija Tao did six months of road testing by using the device in a classical diesel car, a Mercedes Benz. The device helped the car increase its mileage from 32 MPG to 38 MPG on highway traffic, and by 12 to 15 percent in town.

“We expect the device will have wide applications on all types of internal combustion engines, present ones and future ones,” Rongija Tao wrote in the study published in Energy & Fuels.

The professor is still working on his invention, and wants to apply it to gasoline, biodiesel and kerosene powered engines. If he succeeds with kerosene, it means that planes will have great fuel consumption reductions.

The Temple University wants to patent Tao’s invention. California-based firm called “Save the World Air”, Inc., has been licensed to use and commercialize the technology.

Joe Dell, Vice President of Marketing for STWA says the company is currently working with a trucking company near Reading, Pa., to test Rongija Tao’s device on diesel-powered trucks, where he estimates it could increase fuel efficiency as much as 6-12 percent (again, big consumption reduction figures). He predicts this type of increased fuel efficiency could save tens of billions of dollars in the trucking industry and have a major impact on the economy through the lowering of costs to deliver goods and services.

“Temple University is very excited about the translation of this new important technology from the research laboratory to the marketplace,” said Larry F. Lemanski, Senior Vice President for Research and Strategic Initiatives at Temple. “This discovery promises to significantly improve fuel efficiency in all types of internal combustion engine powered vehicles and at the same time will have far-reaching effects in reducing pollution of our environment.”

Again, this invention is good, but it has to be brought up quickly and safely for everybody to enjoy it. My opinion is that still electric cars are the automobile’s future. Until we can be 100% certain that 100% electric motors could drive everything (to be read: we’ll have the batteries to drive them efficiently), these intermediate technologies are still good at important fuel consumption reductions and helping the environment until we come up with something else.

  1. It’s very sad that this stuff gets published in a blog passing itself off as “green”.

    Then again, it’s the internet.

    btw, if you actually believe this works, please stay away from heavy machinery, electricity, inflammable liquids and normal people.

  2. Actually it is true! We have developed a magnetostrictive device that fits in the fuel line as well. It does the same thing. It lowers the surface tension of the fuel as well as produces a fraction of smaller molecules that vaporize at lower flash points thereby creating more oomph per power stroke hence creating better gas mileage and lower harmful tail pipe emissions.
    Problem is that modern emission controlled vehicles defeat attempts such as these to the degree that they cause the air fuel ratio to enrichen to compensate for more O2 in the exhaust gasses. Really stupid the way emissions control systems do not allow for cleaner exhaust emissions!
    There are tons of ways to improve ones gas mileage other than fuel alteration or additives but until emissions control systems contribute to such additional improvements, people will continue to be highly skeptical regarding gas mileage improvment devices.
    I do have yet an even better design than those featured but I do not currently have the financial wherewithall to carry out the small amount of R&D needed to proof the concept. It is largely based on known principles and concepts that have already been proven. The latest design is more of a material change than anything else. Saves costs and energy consumption and is not magnetostrictive.

  3. This is purest BS. There is no way that this could improve fuel economy because it does absolutely nothing to the fuel. One might as well say an incantation over the fuel instead. Just another scam.

  4. I do not know how magnetic field could affect the viscosity of
    fuel that is not magnetic. It would seem that heating up the fuel
    under high pressure before it going through fuel nozzle would be
    easiest way to increase viscosity. The high pressure is needed to
    avoid boiling which causes number of problems that we do not need
    to go into now.

  5. Once again proves what many have said all along. A better mix makes for better mileage. And vapor in more power out. If car manufacturers would vaporize the fuel then mix it with air the mpg would go up 50% percent+ and power would go up while emissions down. Some claim 100% mpg increase with fuel vapor systems that they are using now. Then add water, hydrogen etc etc. there is no reason for a 12mpg car when 50 mpg cadilac is possible and has been built. Mit proved the how and why the 100mpg carb worked with gas analyzers and showed why gas additives introduced soon after the patents release do little else but stop the 100 mpg carbs function in a few days to weeks. but even then the 100mpg carb still boosted mpg over 30%
