How an HHO generator works and helps you save gas

An HHO or Brown gas generator is an interesting and often misunderstood technology.
The Brown gas generator uses electrolysis to split water (H2O) into it´s base molecules, 2 hydrogen and 1 oxygen molecule.
This is why it is often referred to as an HHO gas generator.The HHO in itself is not an alternative to gasoline but a additive
to boost the efficiency of the engine. Gasoline engines are unfortunately not burning gasoline to its full potential. See http://en.wikipedia.org/wiki/Engine_efficiency
The average gasoline engine in a car is about 18% to 20% efficient. That leaves a lot of room for improvement and Brown gas is one good way of improving the efficiency. The reason for this is simple, the hydrogen is highly flammable much more so than gasoline so when your engine ignites the hydrogen the explosion ignites the gasoline with much better results (cleaner, less waste and fewer emissions) than it would otherwise have done.

Some basics the burn speed of hydrogen is 0.098 to 0.197 ft/min (3 to 6 cm/min) compared
gasoline´s 0.00656 to 0.0295 ft/min (0.2 to 0.9 cm/min).

The hydrogen explosion is so fast that it fills the combustion cylinder at least 3 times faster then the gasoline explosion and subsequent ignites the gasoline from all directions  (it is like putting flue on a fire), instead of just a spark in one end of the combustion cylinder, and we would like to do that because the gasoline only has a short time in the combustion cylinder and if its not fully burnt in that short amount of time then it just goes out the exhaust and is lost.It is also preferable to ignite all of the gasoline when it is under maximum compression in combustion cylinder to get the maximum amount of energy out of it (this is a small time window),whonce the piston starts going down the energy transfer from the explosion to the engine becomes less efficient.

The hydrogen´s higher burn temperature and explosive force is such that it cleans the soot that collects in the engine (it is like having the engine consistent maintains) and with a cleaner engine you get better mileage and fewer oil changes .

I'm pretty sure the additional electricity your alternator has to provide to generate the hydrogen outweighs the additional efficiency provided (a.k.a. perpetual motion). Throw some large solar panels on the top of your car/truck to power the HHO generator exclusively and then you might have something.
You couldn't be more wrong. There is a lot of unused power generated by the alternator that simply gets sent to ground once 14.4v is achieved with the use of a properly tuned system one can make use of the otherwise &quot;waste energy&quot; for hho creation. Additional power will be created by the more complete burn of the already existing fuel in the combustion chamber. The use of a pwm (pulse with modulator) is ideal for such tuning. EFIE is used to resist the signal coming from the oxygen sensor. The oxygen sensor sees the additional oxygen (the &quot;o&quot; in your hho) and reacts by asking for more fuel.
<p>There is no unused power. The alternator is instructed by the voltage regulator (which may be built into the computer) to produce only as much power as is needed. </p>
Yes, but that doesn't mean the altenator is functioning at it's max capacity, right?
<p>I know Ford. The 'oxygen' sensors are in the exhaust manifolds just forward and aft of the catalytic coverters. Since, the brown gas is stocichiometric due to process, there should be no increase in oxygen at exhaust. I would theorize that there would be a reduction of oxygen sensed if the gasoline combustion is 'more' complete. Perhaps the reference is to the mass-air flow sensor which is at the air intake? Then I could see that indroducing more oxygen in the air intake system would have an effect, if there were oxygen sensors in the mass-air flow sensor, which I believe there is no oxygen sensers in the intake system. The only oxygen sensors I know of are in the exhaust system.</p>
<p>Okay - after looking at the description of &quot;EFIE&quot; function, I assume that an EFIE is added when oxygen is added such as when injecting Nitrous Oxide.</p><p>With HHO there should be no increase in oxygen. Could the EIFE also be used to compensate for the decrease of remaining oxygen in the exhaust?</p>
<p>huh?! Modern Alternators have 90A+ capability, PWM based regulators and a steady regulated output voltage of 13.8V. A correctly functioning alternator will have 0A output at 0A load. You should upgrade/replace your alternator if it operates as you describe. Also if this system causes the ENGINE to run lean then you run int detonation, worst case = spun rod bearings or melted pistons.</p>
<p>there is not waste energy, there is more energy potential. And alternator or gererator use mecanical energy to make electrical energy, the more power you ask at the generetor, the more mecanical energy it need to make it. Think of a small dynamo you had on your bike. When the light where off the dynamo was easy to turn and all was well, not turn the light on, and you had to work a lot harder to acheive the same speed.. </p>
<p>You may want to check your theromodynamics again. Every system has waste energy. And as the only energy source is the gassoline that's a problem.</p>
<p>Gio, Please learn how an alternator works as it charges the battery.</p><p>A lot of energy goes to waste when the alternator change the engines mechanical energy to electrical energy [used for electrolysis] and no electricity is <em>grounded</em> when the battery is fully charged.</p>
Hi, I know that perpetual motion at this particular period of time is not possible, personally I believe it will be a reality one day but that's another topic. The thing that concerns me a little is the amperage required. I have heard numbers like 29 amps. That is considerable, the question is what will those additional amps require? Well, it will make it harder to turn the altenator, there by requiring more power in order to spin it, robbing the engine of some of it's, HP. But that's (as far as I can see) not really the question here. What I mean is that if we look at the current in vs the hydrogen out, I would agree that there is little doubt that the amperage would out weigh the hydrogen produced, hence illustrating that it is not perpetual motion. But I think we should also remember that 1, apparently the hydrogen enhances the burn of the fuel by virtu of it's higher and more complete burn scenerio. Apparently, and I didn't relize this until recently the efficiency of the typical internal cumbustion engine is not that high, again I have heard (second hand) that it is around 30%. That kind of surprises me. I am going to inquire about that. Anyway not only does the hydrogen burn hotter, it also burns faster and this apparently aids in ignighting almost if not all of the gas o2 mixture. So if we can reduce the amount of gas because of the increased efficiency then I could see how less fuel would be required, if we adjust the o2 sensor to permit the difference in efficiency, I guess we can do that? Let's not forget that the hydrogen is also going to expand thereby helping to increase the compression as well. The altenator is part of a closed system that puts out more electricty than what is needed, yes it will increase the resistance to spin the altenator but to the point where we loose enough hp to increase the fuel consumption to the point of burning more fuel that without the HHO generator? I think not but I'm not sure. I would guess no though. I mean, I think our present set up with internal combustion is far from perfect and I'm sure we have all heard the stories about carberator's that have been deveoped in the past with far greater efficiency than anything we have ever seen but the blue prints have been bought and shelved by those of us who benefit from the volume of fuel burned. If not I have heard stories of that nature going back decades. All I'm saying is that I do believe it is possible to increase the level of efficiency, especially if what I have heard is true and it's only 30%. I hope it's true!
No one is saying this is a perpetual motion something for nothing. Hydrogen gas is cheaper than gasoline if you make it yourself, like a home-made apple pie is less expensive than a commercial one.
Yeah he's got a rather poorly designed pseudo electric car. Forget the fact that even with a pretty good energy source thees devices can't produce that much gas/minute. producing the same amount of force from thees it take 3 times the mass of water then gasoline. You rarely see one of thees devices with more than a few gallons of water. And again is you have the perfect device at the theoretical best efficiency 94% (best devices ever made are in the range of 70%, I've not tested this device but a device in a lab under perfect conditions are working at 70% this ain't even close.)
For every gallon of water you can get 4707 litres of H2, thats at atmospheric pressure and freezing point. So, it would seem on the face of it that H2 production by electrolysis is worthwhile. I agree the main problem is producing enough to properly suppliment your current fuel, but this talk of inefficiencies and costing more to produce than it delivers is hogwash. The weight of an H2 generator is under 10kg fully loaded. The H2 generated will improve combustion, reduce emmissions and should save money long term. Thats 3 positive benefits. &quot;There are none so blind as those who will not see&quot;
<p>On an enegy level, there is no difference, no improvement.. but on the COST side, yes there could be a lot on money saved.. water cost a lot less then gasoline (unless you drink Perrier) but tap water in here is cheap, real cheap and if it can help some fuel.. that is where someone will save.. But not on the energy ratio created.</p>
<p>If the electrolysis of the water and combustion of the brown gas were 100% efficient (which physics tells us they aren't) there would be no net increase in energy produced by the engine. So no burning brown gas produced by electrolysis is more costly. IE it is infinitely more costly. You are wasting money to do nothing. But as said above that is if the system is 100% efficient, it only get's worse when we start talking about 30% efficient engines and 40% efficient alternators and a electrolysis device with no known measure.</p>
<p>Flat out no it doesn't. Messing with the O2 sensor changes compression increases pollution and damages the vehicle. Adding the trickle of brown gas does just about nothing either way. Don't trust me. Look up tests where the system is turned on and off without messing with the O2 censor. Hell do it yourself. Efficiency increases when the brown gas generator is off.</p>
3 ways to easily bypass the O2 sensors, remove them, remove the cat(s or fool the ecu into thinking your not running too lean. If you take off the cat(s) you gain a much free'r flowing exhaust. If you then are able to produce sufficient hydrogen to effect efficient combustion then you will have a cleaner burning more efficient SI/CI engine. Just bypassing or removing the O2 sensors wont have a detrimental effect on the engine, it will have a detrimental effect on the cat(s), so best to remove them.
<strong>That's </strong>the spirit!
Actually, modern day alternators are designed in such a way with such thick windings that the average auto owner will never use more than 50% or 60% of the what the alternator is capable of producing. That includes when you have all your lights on and every accessory in the vehicle going simultaneously. Auto makers have put over sized alternators in their vehicles(at least the domestics) since the mid to late 80s. Which consequently is about when they started EFI (Electronic Fuel Injection) as a standard, which an HHO application would require to have any effect anyway. The alternators used in modern vehicle's use electro magnets and voltage regulators in order to be able to restrain the alternators way back as to not over charge the system. Your HHO generator would have to be putting quite a draw to really have much, if any, effect on your engine or fuel consumption. <br><br>Long and short, your analysis isn't INCORRECT entirely. There are clearly some variables to be considered in each case. However your line of thinking is more in line with the generators they used to put in vehicles in the 60s and earlier, which had permanent magnets and were affected by every extra voltage draw as opposed to the alternators of today with electro magnets. <br><br>Please excuse my rant, I'm by far no chemical expert, I'm just starting my research on HHO generators in automotive applications. I do however know cars and quite a bit about generators and building them, so I just wanted to throw my 2-cents in. Thanks, this rant was fun!
<p>Darkstar is correct, even though an alternator is capable of producing more than what the vehicle needs to run the electronics. It is only generating what is required. There isn't 100 amps of current being generated and simply waiting to get used. As you increase energy demands the magnetic field inside the alternator gets stronger, the engine uses more fuel to overcome the stronger field and in return outputs more energy to meet the demands of the system. The question at hand is, if you have a system that is running at 30A and you add an hho generator that wants and additional 10A. How much more fuel do you have to burn to overcome the additonal load? And how does that compare to the efficiency the hho adds to the combustion process?</p>
<p>Seems to me that no one knows how alternators work! An alternator deliver only what is asked by the complete electrical system.</p>
<p>I do however know cars and quite a bit about generators and building <br>them, so I just wanted to throw my 2-cents in. Thanks, this rant was <br>fun! ........To control voltage and current output of all car generators and alternators, the current flow through the field/rotor electro magnate is altered. No permanent magnets is/was used. Some residual magnetism of the generator field coil core is there to start a generator working [They must be polarized correctly]</p><p>A medium sized vehicle will use 1 liter more fuel in an 8 hour day driving with lights on on a smooth level surface at 60 mph with no wind blowing.....Think how much this system will waste.....Better just feed some water to the intake when the engine is hot and stop adding water 30 minutes before the engine is stopped. As very old motor mechanic and motor- teacher I advise that you stop wasting your time on this brown gas system.</p>
So u say that electrolysis of water takes up more energy than hydrogen explosions?<br>Hydrogen burning=Chemical energy harvested<br>Hydrogen separating=bonding energy destroyed<br>I know u are applying conservation of energy.<br>But the energy liberated after burning H was not the energy provided by electrolysis.It is chemical energy,it was already there.
Bond energy IS chemical energy. Breaking the bonds in water molecules requires exactly the same amount as is released when those same bonds form in an explosion. wikipedia enthalpy if you would like to know more.<br>The problem is though, that alternators are not 100% efficient, and nor is the electrolysis process, due to electrical resistance. Therefore, it takes more energy to split the water you get back from the combustion.<br>HOWEVER<br>To my understanding, correct me if I'm wrong, but using HHO as a fuel additive isn't as simple as getting only as much energy as the HHO provides, but I think it actually improves the efficiency of the petrol combustion, so you would end up getting more out of your engine despite working the alternator extra hard.<br>Can someone confirm this?
During electrolysis,H20 separates,so molecular bonds are broken.<br>during HYRDROGEN explosion,I don't know the actual REACTION EQUATION.So I maybe wrong there.But understanding the amount of energy evolved in a hydrogen gas explosion I don't really think it is supplied by the battery.
<p>Petrol consists of many different chains of molecules which ignite at different temperatures thus is burn very fast but it does not explode! If your engine detonates, you hear a pinking sound [part of the fuel mixture explodes]. This is bad for the engine.</p>
Sorry I didn't really understand your response, but am I right in thinking you meant to say:<br> &quot;Electrolysis supplies energy to breaks molecular bonds. Hydrogen gas explosions release a lot of&nbsp;energy, which was not originally put in by the battery&quot;.<br> If that's what you meant, then this is my reply:<br> <br> The equation for electrolysis of water is as follows<br> 2H<sub>2</sub>O&nbsp;+ energy =&gt; 2H<sub>2</sub> + O<sub>2</sub><br> <br> The equation for combustion of hydrogen is thus<br> 2H<sub>2</sub> + O<sub>2</sub> =&gt; 2H<sub>2</sub>O + energy<br> <br> It's the exact reverse.&nbsp;Hydrolysis&nbsp;is just a backwards explosion.<br> If you don't believe me there, here's something to ponder...<br> <br> The first law of thermodynamics states that &quot;energy can be neither created nor destroyed&quot;<br> This means that the total energy of the system, in all its forms, must be equal both before and after a reaction. So...<br> If the system has x amount of energy, provided by the battery to&nbsp;electrolyse&nbsp;the water, where does the extra energy come from which is released by the hydrogen explosion?<br> The energy has to be in there originally, to be released, so according to your explanation, if you electrolyse water, then combust the hydrogen, electrolyse that same water and repeat 100 times, then the hydrogen would eventually run out of energy because electrolysis doesn't put back in as much as combustion releases...<br>
All you say is right,provided the explosion reaction reaction of hydrogen is the same as you have written.I don't know,though that's logically right(the reaction).<br>So,yes if thats right then the combustion helps in the fuel burning properly.<br>:P Thanks :P
<p>Yes... I have tried a locally made fuel saving device which produces HHO, has given me an additional mileage of 30% in city and more than 50% on long drive in my 2 wheeler. I am from Mumbai, India.</p>
<p>can you share your schematics for my 2 wheeler Fi automatic scooter... 125cc...</p>
<p>Right on the head for the solar panels! Since the govenrment charges us for the water, maybe someday they might charge us for the solar rays we harvest! LOL!</p>
<p>During the past three years, I've made myself three HHO generators by studying plans on the web and test driven them on three different cars, but all old twin barreled carb types. There's many trolls out there, who are very skeptical, who've never done it, tried them out, yet criticize. The Mitsubishi was a 1600 cc, the Mazda was a 1300 cc and the Nissan was a 1500 cc. The average improvement on fuel consumption was 15 - 24%. Recently, for larks, I hooked on a Shell Solar PV Panel of 45 watts (Panel surface area - 19&quot; X 39&quot;) and I was amazed that the production of HHO was quite healthy (My electrolyte base is a mixture of Lab Grade KOH + Distilled water @ a dilution rate of 8 - 10%). Like this article mentions with clarity, HHO is not an alternative fuel, it is simply, a healthy, simple additive. There's a lot of definitive plans around of making HHO work for you, with EFI engines by overriding the O2 sensor using EFIE systems. As far as taxing the alternator and battery is concerned, this is highly exaggerated, it's a load of bull.</p>
<p>a friend of mine made one out of 2 - one gallon pickle jars and he is getting 20 MPG out of a 2004 Ford F250 V10! I think I will go with having one than without. oh and hes running over sized tires which will drop fuel mileage... if he was running the correct size then its my guess that he would get around 25....</p>
<p>HHIO systems absolutely do not reduce your energy costs. It is a scam, outright. The two problems are the second law of thermo and amount of power required.

<p>I think everyone is making this more complicated than it really is.</p><p>The main issue is the cost of fuel. If I get 10 MPG and the cost of a gallon of gasoline is $3 my cost per mile is $0.30.</p><p>If an HHO generator increases my fuel efficency by 20% my CPM drops to $0.25 (plus the cost of a gallon of water). Let's say the HHO generator gives me only a 10% increase in efficency but a gallon of water in the generator lasts me 1200 miles since one gallon of liquid converts to about 166 cubic feet of gas. (lets do the math shall we?)</p><p>Without a HHO generator 1200 miles @ 10 MPG x $3 = $360 </p><p>with 10% increase in efficency... 1200 miles / 11 MPG x $3 gallon = $327.27 + $1 for a gallon if distilled water (with the HHO generator).</p><p>with 25% increase in efficency ... 1200 miles / 12.5 MPG x $3 = $288</p><p>with 40 % increase in efficency (a stretch in my opinion but some have claimed) ... 1200 miles / 14 MPG x $3 = $257</p>
<p>obviously you have to factor in your start-up costs and your cost of maintenance (electrolyte) but the claim is that hydrogen as an additive to a fossil fuel engine has a hotter, faster burn rate.</p><p>Gasoline ignites around 232 C and burns over 945 C.</p><p>HHO will autoignite around 570 C but can burn over 2000 C. That ability is what increases the burn efficency of normally wasted gasoline vapor.</p><p>I guess in general I'm trying to say the more complete the exothermic reaction of the fuels within a confined space the more cost efficient it will be. The reason (in theory) an HHO generator could result in a cost savings is because of the huge difference in the cost of the two fuels involved.</p>
Have to tell u that is working. I was a sceptical in the beginning but now i believe 'couse i have in in my car. It does a small amount of millage increase (800ml/100km) in a vw tdi 2003. As i see some r worried about the amount of watts consume by the a cell. Well i got the answer for that. For a 4 cilinder engine from 1L to 3L u don't need to much hho. Is like 1/8L per Liter engine. So the max u need is about 0.750ml of hho. This amount u can have it from a 3-4 watt. Wich is like 56 watts. Is what a low/high beam bulb will consume. Of course if the engine is like 2L than all u need is 250ml of hho. Wich can be obtained in way lower amperage. So my solution was changing the bulbs with a LED ones. Both consume 3 w wich is 42watts. Normally both bulbs consume 110watts. This way u use max 100watts. So u still have an extra 10watts to use as u like. My engine is 1.9 dti and is running beautiful. Let's get real, u won't get economy of like 2-3 liters /100km. But to me the 800ml is good enough. So we ended up the power consumption from the alternator. Great!!! But the big gain is in the gasses emanates the exost (engine). Noone knows till he try this hho on the car and smell the gasses. Total difference. Well another big gain is the carbon deposits on your intake manifold and also in the end after burning(don't know the name now). Saying all of this i will apologize for my English been the second language for me. But all I have to say is that is working. Soon i'll upload a video with the results /100km. With and without hho. So all of u nonbelievers try first and then talk.
<p>So you make hydrogen from battery power which is generated by the alternator driven by your motor which is supplied by fuel? So you use more fuel to add some hydrogen to the fuel?</p>
No the car is started off of regular fuel the battery is already receiving enough energy from the alternator so the energy the energy that's being robbed is barely noticeable when the pressure in the hydrogen cell gets high enough the hydrogen fuel goes in through the air intake so when the engine opens to basically inhale air it pulls some hydrogen in too so the car isn't trying to do anything more than it was already doing the difference is is that the car won't have to use as much fuel in the combustion chamber to move the piston down it will use a smaller amount to receive the same input so imagine if this is how it was broken down.<br><br>Only an example not real values from an experiment<br>(1unit of gas + 1 unit of oxygen + spark= 2 units of power <br><br>With the hydrogen cell it'll be like this <br><br>1/2 unit of gas + 1/2 unit of hydrogen + 1 unit of oxygen + spark= 2 units of power)<br><br>In the end you received the same output power with less fuel input and we all know it's cheaper to put water in the tank than it'd be to put gas so the savings would be outstanding. Use this in your daily driver to save gas.<br>
<p>Nah, this won't work.</p><p>2 units of power + 1 unit of water -&gt; 1 unit of HHO + heat</p><p>1/2 unit of gas + 1/2 unit of HHO -&gt; 1 unit of energy + heat</p><p>Engines are about 40% efficient, that HHO generator too isn't very efficient. Energy conversion law, you can't get out more that you put into it. (If you would heat the fuel to a few million degrees and the atoms would fuse together, then that would be another thing.)</p>
This instructable is nonsense. Installing this into your car and modifying the O2 signal will at least just waste MORE gasoline, worst case cause irreversible engine damage like melted pistons, burnt valves, possibly blown head gaskets or spun bearings. <strong>YOU HAVE BEEN WARNED!</strong>
<p>Has anyone here built one of these and installed it? I'd be interested in your feedback. What's your experience been?</p>
<p>i have two sets of plates in container, one is taking 7 volts and 14.5 amp, where as second one is taking 8 volts and 9 amps. can any one of them be tried to run electric generator of 1 kw capacity?</p>
<p>how much amp and volts should be needed to run 1 kw electric power generator?</p>
<p>don't you only want to add the hydrogen to the gas and not the oxygen. i think if you just add the HHO as is, in it's perfect ratio the propensity it will take is to just reform a H20 molecule and not in acting as a catalyst or fuel accelerant of any kind. There should be ample oxygen in the air mixed with the gas to combust the H2 and ideally it doesn't just form a steam molecule that you paid to separate in your generator and reform in your engine. If you hydrogenate the gasoline, what occurs? I'm sure they've been done on saturating gas with hydrogen and oxygen separately and i'm certain they've been done trying to add peroxides. For God's sake don't try to add peroxides to any fuel to increase its efficiency, just ask a submariner.</p>
