How HHO gas save fuel for cars/motorcycles?

I found the following summary of on-demand HHO system explains clearly how and why HHO gas can be used to cut down fuel consumption in vehicles.

I remind you one thing Stanley Meyer the frontier of HHO technology got murdered by TPTB years ago.

Back in the good old days, before there were computers in cars, experimenters were able to add HHO to their engines and get remarkable mileage gains and dramatic decreases in emissions. No other handling was needed to get excellent results. Similarly, diesel engines, even today get excellent results with HHO and need no other handling.

However, with the advent of the computer, fuel injection, oxygen sensors, and other sensors used to control the air/fuel ratio, a problem is introduced into this simple technology. The problem starts like this. When hydrogen is introduced, and the engine is turning more times with less gas, one of the results is that there is more oxygen coming through the exhaust. This is reported to the computer by the oxygen sensor(s) that are installed in the exhaust pipe(s). The computer reads this additional oxygen as a “lean” air/fuel mix. It then promptly adds more gas, until it “sees” the same exhaust conditions it was programmed to expect. However, it is now incorrectly adding gas when it shouldn’t.

People with modern, fuel-injected cars, who put in HHO, often report that their vehicle runs smoother, and has a dramatic increase in horsepower. But they also often report no increase in fuel mileage. This is because the computer, that was designed for inefficient combustion, is adding much more gas than is actually needed. What is needed to get all the gains available to this technology is to compensate for this additional oxygen in the exhaust.

A device was created that does just that. It’s called an EFIE, which is short for Electronic Fuel Injection Enhancer. You can find out more about this device, and how it works in the article EFIE Described. But basically this device compensates for the additional oxygen appearing in the exhaust, and allows the computer to do it’s job correctly when an HHO system is installed.

  1. I think HHO gas burn itself 2H2+O2= 2H2O
    fastly so promotes complete burn with good timing after 15degree after top dead center.
    And leave ideal exhaust gas states.
    Power increase then driver donesn’t need press deep the gas pedal, so advanced higher gear driving possible. so it leads gas saving.
    It’s same like Cyclone- my invention device.
    Problem is unburned fuel at present EFI engine, Cyclone make air swirl in engine for more complete burning. See my website
    Altoghter Cyclone and HHO good matching in motorbike, gasoline EFI, Diesel also…..
    I worked at KIA motor co, 10 years in R&D.
    And I did Cyclone air swirling device selling over 22 years.
    Also I want to added about EPA -Fuel saving testing, carbon balance testing is fully wrong, they tested CO2 gas, I and all clever people strongly insist correct testing way is checking consumed fuel per same driving distance.
    Cyclone laboratory test result shows all 3 harmful gases all reduced down , but at the same time CO2 gas is all the same with or without……in each city and highway condition. And FE-fuel economy data shows +/- 0, but in highway test with 1 unit of Cyclone 80Km/H constant speed Nissan Maxima EFI, and Oldsmobile EFI auto T/M 24%, 22% saving fuel.

    Clean burning of fuel gives more horsepower so it definitely reduces fuel consumption like you said. Lower RPM of engine using your device or HHO kit will produce the same amount of power of conventional engine at a high RPM.

    But to increase fuel mileage the actual amount of fuel per cycle needs to be reduced either tweaking sensors of engine computer or rejetting carburetor needle.

    I’ll buy a 50cc or 100cc used scooter for HHO experiment soon to save fuel money. I have no intention to provide fuel saving service as business, which probably put me in jail due to so many stupid regulations and laws in South Korea.

    Do you know that 1980s Honda Civic has more mileage than most hybrid cars in these days? It’s so pathetic how whole auto industry exploit customers. GM Cobalt is a joke. Hyundai hybrid car is laughable too.

    • Saving fuel is really possible by more power and using higher gear driving….
      So good car maintenance also important, because even sensors also must be replace if it’s function bad or wrong, and I insist driver must use good after market products, if it’s real good. But wrong savign fuel testing method must be changed, like USA EPA carbon balance method, checking by CO2, not by consumed fuel amount.
      *Latest vehicle use EGR- exhaust gas recirculation for reduction NOx by lower engine temperature, but engine need fresh new air, not dirty gas.
      I mean Cyclone my invention also reduce NOx by more working in engine.
      We have test data for that…….
      And HHO also cooling gas temperature, you can imagine all water engine, meaning 100% HHO gas engine will leave almost no harmful gases.
      * Also they must equipped catalitic converter, but it gives back pressure so power drop and bad milleage, also I find it carck down some times by un burned fuel wet there and fire and burned it.
      If that car fixed Cyclone , by complete burn effect, that can be preventer also…..

      I’d like try to develop car engine drive by HHO gas mostly….
      For better environment and economy of many drivers…..
      In that case Cyclone must be used, why? H2 has is so light so it can adhere at top somewhere intake hose, with Cyclone it swirls up and rushing to the engine and makes it fast burn……….
