    Has anyone ever modified there engine to accept HHO gas? I was doing some research and was thinking about trying it myself. There are a bunch of Youtube videos on this subject.

    As a rodder and general tinkerer,I have built a few different designes of these water to gas devices.my conclusions are ,1.they work ,to a degree 2.you must drive with as low a revs and as high a manifold va***e as possible . 3.constant monitoring of the unit is neccessary 4.some minor adjustments need to be made to the engines timing .5 . the device works better on older petrol and diesel engines than more modern computer ***isted jobs . For me ,it was worth it and I am refining to sharpen the sweet spot .

    I have not built one, because I understand the chemistry/physics of it a lot better than most tinkerers (I'm an engineer), so I know it's all complete ********.

    But I expect you could get better mileage by driving with low revs....that's why they put overdrive in newer cars, and they get a lot better mileage than the old ones did.

    It would be fun to play with one, and do some real testing (using double blind techniques, so neither the driver nor experimenter knows whether or not it's turned on during a particular run) but it would be a waste of time publishing the results, because the tinkerers would claim that I'm part of the big oil company/carmaker/gummint conspiracy to cover it up

    The digital fuel mileage indicator on my ot daily driver shows real quickly that engine rpm is quite directly related to fuel consumption. 55 on the flat equals about 25/26. 70 on an equal flat road equals the epa rating of 18 or so. Above 70 calls for looking for the next gas station in a hurry.

    I'd say that having the proper state of tune on the engine and having the final gear ratio right would be the most beneficial for fuel mileage and forget the add on's.

    That effect is not really an RPM thing, it's a MPH thing. At those speeds a small increase in speed results in quite a bit bigger increase in air drag. Drag is exponential....

    Watch the mileage at a constant speed, but in different gears (shift the transmission) see what happens.

    It is complete ********. until you invent a cold fusion machine, tinker with an electric vehicle.

    None of these under hood devices produce enough Hydrogen to make enough difference in an Internal combustion engine. Why do you think NOS comes in a large container under a lot of pressure??? and how long does a charge of NOS last????

    A fool and his money are soon parted.

    The only benefit from HHO would be if it makes you go easy on the loud pedal and increase the mpg yourself. If you really want to prove to yourself it wouldn't work, look up the BTU content of hydrogen and gasoline and do some quick math as to how much hydrogen would be needed to start displacing gasoline.

    Totally agree.
    Ahh the laws of physics ; energy in = energy out.
    I think if you add some snake oil it would work best......
    But but just don't mention that if you use refrigeration as an example ;energy in = up to 4x energy out.( but the devil is in the entropy).

    We did some hydro builds at my last job. It was thought by this particular group to use it in m*** transit type vehicles like airport buses and the like to reduce emissions in areas more compacted with such. There were 6 gigantic tanks out back that needed a forklift to install and service (lots of that) and each one was substantially pressurized. It did p*** a 45mph rear crash test, used a supercharged engine, ran almost like normal and required just under 2hours to fill. Mileage was no better than the same on gasoline that carried more poeple (no tank module). I heard last year that that particular OEM has dropped hydrogen research completely for now. The expense is impossible to recover for the manufacturer and even worse on the consumer.

    If you're talking about those onboard hydrogen generators that take power from the car's electrical system and use electrolysis to turn water into hydrogen gas and then feed the gas back to the engine tp produce power, they're bogus. That's not just me saying this - the laws of physics state this. (see the 'Law of Energy Conservation' and the 'First Law of Thermodynamics') Energy cannot be created or destroyed....it can only be converted from one form to another. Anytime you convert one form of energy into another, you always have a net loss - usually in the form of heat, light or electro-magnetic radiation - and you have to put more energy in to compensate for these losses than then you get out. That's why perpetual motion machines don't and can't work. The onboard hydrogen kits on the market - ebay and the internet are full of these scams - always take more energy from the car's electrical system then then the energy they give back in the form of hydrogen gas. Guess where the energy for your cars electrical system comes from? From the engine driven alternator that uses power from the engine to produce the electricity used to produce the hydrogen, all at a net loss. They'd only work if you had a free source of onboard electricity to produce the hydrogen from - and if you had a free onboard source of electricity, you wouldn't need a gasoline burning internal combustion engine in the first place. There ain't no such thing as a free lunch....no matter how much people want to believe there is.

    Saw a couple guys here try to build those things. They were testing on a early nineties F150 with a V8. Two units, each drawing 60 amps each! They kept frying out the relay boards they built, but finally got a system to hold together just before taking out the truck's electrical system. Pretty funny to watch them do it, they never gathered data to prove they worked or not and gave up on the concept.

    I postulated that the gas produced has oxygen as well as the hydrogen and would have more gain in mileage than the hydrogen. I would bet an Oxygen tank with a flow meter set to 1-2 cubic feet per minute would have a more positive gain in performance and be a **** load cheaper to set up and maintain.

    Here's the fundamental principle of how those systems work.

    First, a friend of a friend's cousin finds out you're a gearhead.
    Then they tell you all about how their system "from the internet" improves mileage.
    Then you're forced to witness an S10 blazer with some copper tubing and a mason jar duct taped in place of the charcoal canister.
    At this point you try to explain a few laws of physics.
    They're countered with wild stories of how the HHO "tunes the rings"
    You realize the only thing highly tuned is this person, nod, and just walk away.
    The HHO conversion circle is complete.

    IMO, the HHO users are overlooking the obvious. If they spent the time and materials used on the HHO system to create a fume capture system for their meth lab, they'd have more meth.
     

  20. Well put.

    Why would anyone build a rod and worry about fuel consumption in the first place. Econo-rod is an oxy-*****(sic).

    Guys, you're wasting your time. (I am, too, I guess!) Might as well talk to some old guy about Fish carburetors, or magnets on the fuel line. Moth balls in the gas tank is a good one, too. Oh, and by the way, no man never walked on no moon, neither!

    We should get the government to repeal the laws of thermodynamics!


    Quote from a smart guy, with math and stuff..

    "If a gallon of gas has 112,000 BTU, and your fuel rate at cruise is 15mpg @ 60 mph, that's 4 gallons per hour, or 448 kBTU's. To increase the mileage by 10%, you need to generate 45 kBTU's of h2 per hour, or 192 moles (or grams, if a mole equals a gram) per hour. Adding 96 moles of 02 at 32 grams/mole, gives you 3072 grams of 02.
    192+3072=3264 kg (3.264 Liters) of water/hr needed to electolyze to make enough h2 needed to supplement 10% of the gasoline

    If you need 4 electrons to split a water atom into 2 h2's and one o2, need 96 moles of water/hr, then you need 384 moles of electrons/hr, or 2.3E26 electrons. Since it's 1.6E-19 electrons per coulomb, you need 3.68E7 coulombs/hr.

    An Amp-Hour is 3600 coulombs, so you'll need 10,214 AH to feed the electrolysis reaction.

    A volt is 1 joule per coulomb. With a 12.6 volt battery, you'll need 3.68E7 coulombs/hr * 12.6 Joules/coulomb = 4.63E8 Joules/hr
    Since a watt is 1 joule/sec, that works out to be 128,700 Watts.

    That's a pretty damn big power draw on the alternator!

    Much better to just accept the 35% loss in burning gasoline, than add another 2 steps with their inefficiencies"

    Oh man, reminds me of a video I saw a year or two back. GEET, he invented a fuel vaporizer. LOL Highly tuned mind you! It gets real good from 6:00 on....



    I prefer Brown 25 as a fuel. It's far more traditional. :D

    To better understand the concept, let me try to explain this in simple terms that we all can understand. Get a board, stand on the board. Bend over and grasp each end of the board with your hands. Now pick yourself up off the ground. Now does everyone understand? Your welcome.

    i want to try adding HHO to a vehicle, but i want to make the HHO off vehicle using the wind.

    thats funny, back many year ago i saw a "how to" in popular mechanics on how to create power from the wind, they used a SBC water pump as they have a alternator mount, the fan as i remember had 5 or 6 blades, and they just added extensions, this all went up on an old radio tower, my plan is along those lines, i want it to be as inexpensive as possible, just because.
