today
 
I was driving today with the fuel cell turn on / turn off thing....mpg seemed to go up a bit....won't know for a few more gas ups....

possibly use a rising rate regulator for the fuel, set it up for lean at cruise, full pressure under load instead of full pressure at cruise and even higher pressure under load.

4x4s are probably the most difficult to see mpg gains from? Concentrate on the best drivetrain lubes? Plenty of wind resistance. Also one guy testing HHO found a minor gain at higher amps and maybe 15% running under 10 amps. Adjust ignit timing?

Check this?

Zug: I borrowed an idea from a video and experimented on the bench. My unit will be full of water (or very close to) and the bubbler will simply be higher yet. I found that the center of the bubbler put at the water level was sufficient to eliminate most of the water spurting. I deem it necessary to run a dryer in the line after that.
Cugir: I would have thought the opposite. Most gains with HHO come on the smaller motors, and I'd believe that the percentage of HHO to A/F is higher there, as opposed to a v-8. Oddly, some guys have noticed their greater mpg went down when they increased the amps and output, but I think this is a MAP, MAF, or oxygen sensor issue, and possibly limitations built into certain computers (the field range of voltage). It appears that HHO technology used as an additive has many variables we're not even sure of at this point.
I'd be real careful if putting any controls of any kind on the throttle. I learned long ago that gas, steering and brakes are 3 things you don't shortcut on. I'm sure you know that.
I don't believe for a minute that you can have too much HHO, since there are guys running six packs on their pickups successfully. Or so many claim. I'd think it's just a matter of gettng the engine to respond to or use it properly. I'll bet my initial test of my pickup will not show much; I'm not putting electronics on it at first, as I want to see what happens item by item, tank by tankfull.

quadancer@bellsouth.net 06-16-2008 05:05 AM

Perhaps efficiency has something to do with it.
Our little Seo gets about 27mpg with 100 hp. Efficiency is 2.7/hp.
My Silverado gets about 16mpg with 300hp. Efficiency is .0053/hp?
Let me divide that the other way:
Car: 100/27=3.7
Truck: 300/16=18.75 - There, that's more like it. No, wait, I was right the first time: the car is more efficient than the truck. So the amount of HHO is significantly greater to the amount of WASTED gas from the car, as it is much less waste than the truck. For the truck to match the car, it would need to get 81mpg from the factory.
...and I STILL can't pull a load of lumber with the car...

J. Hartley 06-16-2008 06:07 AM

I've just built and installed the HHO generator described on the hho water 4 gas website. So far the results seem positive. I've noticed roughly 10% increase in fuel efficiency over half a tank of gas. I'm running a relatively tame amount of HHO, using about 1 amp of 12 vdc to generate the gas. If I add some more baking soda to the water, the current increases, but I wanted to start small. I'll let you know how it pans out, but it definately seems to have some merit.

efie
 
I got the EFIE board from fuelsaver-mpg today. I used to be an electronics tech in the navy...did a lot of soldering, sold hot air rework equipment to solder surface mount parts. I have to say....I'm not real happy with the way the board looked. Most of it was fine. They weren't careful aligning the "LM2940s" chip. It's slightly over a run. Not seated completely over the pad.

I had my unit running at 15-25 amps. It's too hot. It works but you end up with steam and high heat. High heat will loosen your bolts, even with lock washers. 5-15 amps seems to be better...no heat problems, no steam. I get a decent stream of bubbles. I have 1/2 id tubing so it's not a stream like small id tubing. The bubbler caught any steam but I still don't like that much water leaving the unit. I have about 3 ft of tubing between my fc and the bubbler. The bubbler is a windshield wiper container. where are you injecting the hydrogen? I tried it in both ccv and manifold line...I think the manifold is best.

My motor is a 4 cyl. I have a switch on the dash....it's not a problem turning it on and off on major accelerations. I have a feeling this is going to work. If I stay at my mpg presently it will be wonderful. 20c/22/h mpg is very good for a 100k 1992 wrangler and I haven't added the efie yet. My goal is 25mpg. I won't add the efie until I get a decent feel for the on/off thing in mpg. It is interesting to see the oil pressure rise after 5 or so seconds of the unit on.

Today I road tested the modified Smack unit in the 6x6x4 electrical box.
Readings were as follows when I got home and idled in the drive for 45 minutes.
Amps/Case Temp/Bubbler Temp/Voltage/Output
10 85 75 14.2 L/min
12 133 121 14 -
12 141 134 14 .74
15 151 135 14 .85
15 156 137 14 .88
15 161 141 14 .94
15 163 143 13.8 .99
15 166 148 13.8 1.01
15 169 152 13.8 1.21
15 171 155 13.8 1.03
16 172 158 13.8 1.09
17 174 160 13.8 1.01
17 177 163 13.8 .88 shut down.
As you can see, production decreased over 170 degrees f. case
temperature. I found at shutdown that the lid had warped between
the screws and was leaking.
I did put in the float tank, supply tank on under the hood, and hooked them up to the jenny, but didn't put water in them until after the test, which is how I found the leaking. The float idea ...I dunno, it seems to want to overfill, even though it's lower than the jenny. It worked on the bench tho.

ZugyNA 06-17-2008 02:55 AM

Just guessing...but I think the upper temp limit for good gas production might be around 130-140F. Could be that under higher heat and amps...that more steam or water vapor is produced instead of HHO

I think the smack says 150F or so is his designs upper limit.

When I start to test again...I'll probably shut it off it I see cell temps above 140F or so.

cugir321 06-17-2008 04:03 AM

Here's a picture of the board.

Notice the three legged chip....designation LM2940s. The chip is over a run...it does not sit completely over the pad. This is not a good thing. I'm not real happy with their work.

I got the EFIE board from fuelsaver-mpg today. Most of it was fine. One problem is too much. It only takes one short to cause problems. Will it work? Probably. The run is coated so it should. Could it short...maybe. Do you want a maybe problem attached to your cars ECU?

GasSavers_Russ 06-17-2008 06:46 PM

Its well worth looking in to but as said in the last post A BUBBLE IS A MUST

believe me its not worth doing anything without i have had a reactor go up on me and its not nice,


Its easy to make it with a Bottle


have the in hose (FROM REACTOR) going in through the lid right down to the bottom and the out (To torch car) at the top, half fill the bottle with water and tighten the lid,

This stops any explosions from getting back through to the reactor and protects yourself, if anything now you will pop your lid on the bottle, and not risk yourself, (NOTE) glass jars should not be used,

You can also acheve the same afect useing a tub tightly packed with wire wool sealed at both ends with taped holes,

if there is any more info you would like about this please feel free to Email me,


Never Give up

Along with the Dollar store pizza cutter wheels?

You might want to add a simple bubbler to avoid flashback? Could just be a jar with water in it. The gas bubbles up thru the water before going to the engine...also removes some contaminants.

Interesting pages?

HHO, Hydrogen/Oxygen is simply made by making a sandwich of stainless steel plates in a bath of baking soda and water. Use the 12 volts from your car battery to start the electrolisis process in the plates and viola, you can suppliment your gasoline with a stream of HHO.

The benefits, in a fuel injected car, the O2 sensor will read a rich condition and lean the mix, your burning less gasoline getting better mileage and it only costs you water and baking soda.

So as soon as I buy my next car ( Saturn, Civic, Escort, or Geo), I'll start building some cells and see how much HHO I can make.

Has anyone out there had any luck assembling cells and does the mileage double? From the info on Youtube, it seems the skys the limit. Oh also, if you do build a system, make sure you install back fire valves, so you don't have a Hindenburg under the hood.

Oh, MPG Research has started a column on Hydrogen, this seems to be the fuel of the future, I can't wait to hear the responce. Thank you.

I wanted to let you know about https://hhoinfo.ning.com we are a group of HHO builders who have come together from all over the world to work as a team to figuere this technology out and bring it to the forefront. You should join us. We have people from all walks of life and that is one of the things that makes it such an iteresting system. We get all sorts of ideas running through the system. Not all of it works but the stuff that does is awesome.

it hasn't come yet. But I'm half considering of trying it on my car. My car already burns lean. So what will this mean for my emissions if HHO is making my engine burn even leaner? Will a car with lean burn get any benefit from it?

Do larger cars get more benefit than smaller ones?

ZugyNA 07-03-2008 06:05 AM

I'd start testing with lower amps...maybe 3 cold and 6 hot? Since you are already doing 60 mpg...it ought to be interesting.

I'm pretty much convinced that HHO does improve mpg...the question being whether you just buy a generator or make one and what kind to make or buy.

There is something in investing called "opportunity cost"...where if you don't make a trade...you've lost the chance to make some $....but there is always some amount of risk involved. So you have to balance risk and reward.

Same with HHO...the longer you wait...the more fuel you can use and the more it costs you? At the same time...if you "roll your own" or buy one you can make mistakes that will set you back $ wise also.

I don't think you need a tero cell to utilize HHO...mason jar series cells work just fine if tweaked out right?

The civic lean burn is a stratified charge type, that means there's one pocket of probably near 16:1 mixture that burns and one pocket of pure air. So average is 25:1 but locally the mixture is rich enough to burn. Since H2 injection has been shown by Arvin Meritor and MIT to move the lean limit to about 26:1 in a HOMOGENOUS charge, then a stratified charge type of lean burn system should be able to get benefits from it. However, you do have to ensure that your HHO or H2 get inducted with the charge and not the "spare air" or you might have issues with it, one way to do this might be to regulate H2/HHO induction with the injector pulse when in lean burn mode.

edit: or it might be nice just to replace all fuel maps with the lean burn map and shoot for 25:1 at all times.

HHO has two different meanings. One is a mixture of gases produced from electrolysis of water. The other is a magnetic combination (Google Magangas) which is produced from extreme current arks passed through water.

Since the cat is out of the bag now and it is well known by the readers of this group that producing HHO by electrolysis of water is a very energy wasteful process due to the loss in heat, inefficiencies in electricity generated by alternators spun by fan belts with with friction involved, whose initial energy is created by inefficient burning of gasoline in an internal combustion engine -- that something had to be done to continue this scam.

It is now being claimed that HHO is somehow a "catalyst" that increases the, to gasoline burned and decreases the amount wasted. Wasted gasoline is converted to heat in the catalytic converter. If a sufficient amount of gasoline was on guard the catalytic converter would very quickly become red hot. The fact is that modern engines burn almost all of the gasoline that is injected into the cylinders. The theoretical maximum amount of energy that can be obtained from burning fuel is a function of the burning temperature and the cold temperature. Google "carnot" for the explanation of what's going on.

The "patriot movement" has always been ripe for exploitation because all you have to do is say "the government is hiding this" and they will be there with their checkbook in hand.

Many letters will be written and many kits will be sold and no one will ever get an increase in mileage that is not simply the result of them driving more gently. No one would dare admit that they were taken because they are embarrassed to admit their ignorance.

I am writing this because it angers me that the affiliates and producers of this bogus product are making money from the ignorant. In my opinion you are every bit as evil as the government that you claim is hiding energy-efficient devices.

I've seen these scams come and go for over 20 years. Sucker born every minute.

GasSavers_roy 07-06-2008 11:50 AM

Hello everyone, my name is Roy(newbie, please no cat calls till tomorrow) and I currently have a site where I posted my journey with HHO from purchase to installation. I have a few pics there showing some of the details. The site is located at https://www.houseofbugs.com/weblog/?site_id=308.

One day I said, enough is enough! When the gas prices kept rising, and still are, I decided that I was going to find a better way. I am still working on that.

My first journey was with one of the sites that abound on the internet. I ran across a using water for gasoline post while googling about an unrelated topic.

I didn't take any action, just read the -homepage only-site that was just a glorified ad for an ebook.
I mentioned the site to my sister and in her desire to save on her weekly fuel bill for her family of almost 250/ week, she purchased that book.

Came to find out, that the book was pretty much assembly information using stainless steel tubing made into a tank with a remote water tank to keep it filled.

If that would have been my only experience with this technology, I would have file 13'd that one, but I didn't give up. Main thing is that I do not have time for that kind of assembly. Finding the parts and all that stuff was asking a bit much for me to do for something that I had little understanding or information about. Then the author had some coil you make and place on the top to charge the gas/water mixture in the unit. That was too much for me to handle, I was just trying to find another way, not journey overseas looking for the mythical hydrogen generator.

Well to make a very very long story shorter,
currently my vehicle, a plymouth van, has two jars under the hood(yes mason jars). I had to set them in there the best way that I could because there was little room under there for any sort of mounting bracket.

These jars(purchased unit from a backyard floridian who is making them at his home) are hooked into the intake of the engine via a vacuum hose. There is a check valve in the HHO feed line.

The water inside has 1/2 tsp of baking soda in each jar.
The jars are filled up 3/4 full and there is a water trap in the HHO feed line just in case.

I am currently getting in the mid to upper 20mpg range on level road(per onboard computer-up from upper 13mpg's without the units) after some tweaking,which I won't go into here, but you can go read about it on my site if you are interested.

I am going to put a link to this site from mine. It's good to read some fellow HHOers and their comments. Some folks think this whole hydrogen thing(I coined a term, homeboy hybrid) is a load of crap, but I tell you, us having to pay the big bucks for fuel and get our lives squelched from the associated bills that are rising rapidly at the stores(from rising fuel costs) is the real crap.

Will be back again, bye for now.

GasSavers_roy 07-06-2008 11:58 AM

Hello Fellow HHOers and wannabes
 
Hello all,
Great reading the new posts. My units are still making the gas and the mileage is still looking good on the OBC.
I recently posted on the local news station blog. Fox4 Texas. I currently have a blog I opened there and will be posting a link back to this site on my next visit there.

Fox4texas.com I think it is. The other night this reporter on there had a story about one of the gas saver books for sale online. He invited folks to go there and post, so I did. I don't like the book that he chose though. My sister purchased one similar to that one on her first try to save some gas, and it really was a bit much on the technical side for her.

I could agree with the fact that the reporter couldnt find any mechanics in his sweep that were able to make the unit or install it.
Its one of those fancy stainless steel tanks with electrodes in the top and a backup water tank in the trunk, control panel, and accelerator adjuster...the list goes on for things that you have to make for the system, with no adjustment for the sensor limiters(o2 etc).

He also mentions in the book that my sister purchased, that a person using his system will have to replace the valves eventually, I presume because of the high gas output.

He recommends stainless steel valves, which also was recommended by a person driving a 100 percent water car on his personal web page(don't have the link right now).

He reported that his valves all corroded after a bit on his intial water-gas car experiment and that he replaced them, along with his corroded exhaust system, with stainless steel. Word for the wise?

I think he mentioned a 22k price tag for the valves and exhaust in all stainless steel.

Back to my beer budget project, I am planning to add a few more jars (maybe a 4 pack) to my under the hood setup. These will have to be the smaller mason jars though, mainly because it is all the room that there is, and that will be pushing it.

I have located some plastic mason jar caps at a local grocery store(8 pack made by ball). My original purchased jars have metal lids with gaskets/glue keeping everything separate as far as positives and negatives.

I have noticed that my mileage results(OBC on board computer)go up and stay up for several hours after adding some fresh peroxide to the jars before a trip.

I can do this easily because the guy I purchased my current jars from, installed some small stoppers in the lids for easy access.

I just pull them, pour in the peroxide when I am fixing to go for a drive, and button them up.

I have a large syringe that has some tubing on the end that can be used for withdrawing some of the solution inside of the jars if needed.

So far all of my driving has been city driving.

Bye for now.

hotcubed 07-06-2008 02:52 PM

I haven't used HHO on my car, but my dad uses it on his biodiesel Jetta and it gets a ridiculous amount of increase. I'm pretty sure his average highway MPG without it was somewhere around 40 mpg. Now, he is getting anywhere around 60+ mpg.

I've heard a lot of folks bash it, but it seems to work pretty darn well and give good results for many.

mpcondo 07-07-2008 11:37 AM

I've read a little about using HHO and it seems that the general opinion is that it takes too much energy to produce the HHO so it isn't effective. So I had an idea, and thats all it is just an idea. Will it be effective to use solar energy to make the HHO? I recently pulled four solar panels out of those little solar garden lights that I was gonna just throw away and I wired them together to create a solar powered cell phone/ipod charger. So, I am questioning if the amount of voltage that is put out by my solar charger is enough to created a significant amount of HHO. ( it puts out about 8 voltz)

I wired my solar panels to a usb port, so I figured i could run the wire up to my dashboard or a mount on my hood with a usb plug and plug in the solar charger when I wanted to use it.

Any comments or thoughts are appreciated.

GasSavers_roy 07-07-2008 12:17 PM

Yes there will be increases using HHO
 
Hotcubed tell your dad I hope that his mileage keeps going up...My car is doing great I was out for a while today and noticed the on board going from the teens(starting from zero) up to 70mpg(coasting downhill but in gear).Avg 20 mpg to low 30s on level ground.
Mpcondo as far as the naysayers doing their energy mantra,I hear from this one guy all the time on my blog. His wannabe physicist quotes seem a bit over the top to me. It takes energy to grab that oil out of the ground and process it and then to get it in my gas tank....I have read several places that a car engine is only around 25 percent on its efficiency of combustion....energy waster....then my alternator is turning whether I use that extra electricity that the turning alternator produces or not...so I really don't see where that old "cant use energy to make more energy" mantra has much effect in my energy wasting car that produces more electrical output than it uses...sure maybe in a perfect system that is true, but we are talking about bookoos of waste every time you turn your car on...so I think that there is some extra power to use for my little bottles. Don't you?

montuna 07-08-2008 03:52 AM

I put one of these on my 300d that i had been getting 25-27 with my best mpg coming from a 70% highway trip that got me to 28 and the first half tank of fuel 250 some miles gave me 32.4 mpg. I then ran a full 400 miles and got 31.7. Both tests done with the hho hooked up were 80-90% in town driving, and while i was working as a pizza delivery driver, which means i left the car running when i delivered the pizza 30 seconds to a minute every delivery plus i tend to get on it when im pulling out on country roads. last week i blew the fuse to it and immediatly the car felt slow and it was a little harder to start, but when i hooked th hho back up it felt smooth again... i plan to do a blind test where i have my friends unplug the hho or leave it hooked up and try and see if i can notice the difference or if its a placebo.

There are three companies listed as members of the National Hydrogen Association that sell HHO generators for vehicles. The NHA calls them hydrogen fuel injection devices.

Here is a link to the educational division of the NHA called H2 and You.

https://www.h2andyou.org/caseStudies/injection.asp

According to the site these HHO devices are used in the trucking industry and have logged “50 million miles of real use”.

MAP's and MAF's
 
Hi I'm a new member. I'm in the UK. And have been going through the forums on this subject. As I might consider HHO myself.

Something to consider is how much is one prepare to mess with the EFI system. (MAP/MAF & O2 sensor signals). As far as I can determine the MAP sensor (Manifold Air Pressure) only detects the change in air pressure in the intake system with different throttle positions, and is usually situated between the air filter and throttle body.
So does the injection of HHO at the air intake cause a significant drop in the intake air pressure that is enough to warrant the modification of the MAP signal sent to the ECU?

Pretty much the same applies to the MAF (Mas Air Flow meter). It detects the volume of air flowing into the intake (usually done by a spring loaded flap in the airflow. The wider the throttle opening the faster the air is drawn in, the further open the flap). The signal again sent to the ECU (In both cases as part of the fuel/air mixture control loop).
So in this case, Does the injection of HHO somehow reduce the airflow into the intake?
For example. 1L/min HHO = 6millilitres per second injected just after the air filter. Compared to the volume of flowing in to the intake at a steady cruising speed throttle opening. Does it really affect the intake pressure/flow that much?

Also, as far as I can see you would have to increase/decrease the flow rate of the HHO as the throttle opens/closes. Or else you would effectively have a varying fuel/air mixture depending throttle position. (Closed - Weakest fuel/air mixture - higher content HHO. Open - near normal - due to increased volume (litres/second) of air flowing into intake) Is this the case?

In think you'll find MAF's on older EFI cars, I have seen some cars that have both, But the newer and current cars seem to have MAP sensors. Primarily because all they are, Is a small pressure transduder. Where as MAF's were large and precision mechanical devices, More prone to failing.

If there is either no significant drop in intake pressure (MAP) or flow rate (MAF) there should be no need to modify these signals. Wasting time resources and money on something that does not need to be done.

The O2 sensor is the only one that may need signal modification which also may require a signal from the MAP/MAF to compensate for increased intake airflow vs HHO's sort of fixed flow rate (fuel cell performance).
But exactly what does happen in the burn cycle to the HHO? i.e the hydrogen and the oxygen. Where does it go and if they recombine to form water. How does it affect the O2 sensor signal?

There are a load more questions but I leave that for another time.

I wonder how litres HHO I would need inject per minute to get my best recorded MPG of 32.6 (UK miles) up to about 50 @ 56mph? (Mazda MX6 2.5L 24V V6 164hp - Equivalent to Ford Probe GT). Big fuel cell??

I hope someone can answer some of the above questions. The above info about MAP and MAF is deemed from having to find out how all of the different intake, emission, engine position sensors all worked in order to diagnose a fault of the wife's car. Deemed mostly from manufacturer service data, as I have the manufacturer workshop service CD's for her car which explain how all the sensors work and how to test them.

Cheers

The EPA says these devices don't work as has been reported on the news don't pay for plans you can find free info if you search for it.

It takes more energy to seperate HHO then is produced by it so your alternater will place a greater load on your engine and reduce any gain from the HHO gas. If this worked GM and Ford would be using it to avoid bankrupcy. Don't get scamed

sites like tree hugger say you need a nuclear reactor in tow to run your car on HHO

If it was real the inventers would go to ford or GM and they would make them rich

Prove it to the EPA and get a EPA approved lable if you can do this you will be rich but no one can do this. Don't believe the claims from the scammers

Snax 07-19-2008 05:11 PM

The EPA has also felt that it has been perfectly ok for the oil companies to be dumping the excess benzene gleaned off the cleaner fuel required in some areas back into the fuel we burn here. Woohoo, three cheers for the EPA and the increased rates of cancer!

You also seem to be under the mistaken impression that people are attempting to run their motors on HHO, and while some may be deluded into thinking that is the goal, HHO is NOT the fuel. Instead it is supposedly a combustion aid, propagating a more complete and cleaner burn.

I can't honestly say whether it works to that end or not, but rather that the car manufacturers don't do allot of things for many reasons - not the least of which is produce more efficient vehicles due to demand for higher fuel economy. If they did, we would not be seeing car lots overloaded with SUVs and trucks that they can't sell.

HHO systems simply represent an added liability to the manufacturers, providing one more system that the user must monitor and maintain. Even if the engineering and production costs were dirt cheap for HHO injection, that factor alone would discourage most buyers.

GasSavers_roy 07-21-2008 02:54 AM

I couldn't agree more snax.
Did you hear about Phil Grahams' 'nation of whiners' comments? Well at least folks on here are all trying to find some answers to the gas problems, unlike phil and others who played major roles in most of our financial problems.

I can thank folks like Phil for my huge deregulated utility(electric rates in the .20/kwh range and rising),rising natural gas rates, and rising cable bills(100/month plus) here in Texas. No wonder folks are whining, our world is tripling in cost(and rising) with our paychecks literally disappearing...

My main hope is that the hydrogen injection will not cause major repair issues with the valves.

According to the critics that I encounter on my blog,
the little jars of water will not furnish enough hydrogen/oxygen to do anything. If they are right, I hope that includes the valve erosion as well....

I don't expect it to be a problem, but who knows really?

GasSavers_roy 07-28-2008 11:15 AM

The actual mileage on my car is now down to 12.5(bottles on or off). My mpg on the car puter says differently. I think I will go with the actual mpg.

I am now going to purchase an oxyisolator for my oxygen sensor that is upstream of the catalytic converter. It is claimed that the upstream oxygen sensor in the exhaust line is the one that is a factor in adjusting the richness of the fuel.

The oxyisolator is an extender to get the tip of the oxygen sensor out of the exhaust gas stream.

I talk about this some more at my blog at https://houseofbugs.com/weblog/?site_id=308

GasSavers_roy 07-31-2008 09:43 PM

I have been negligent with my system. I never reset the computer after putting in the jars and covering the oxygen sensors with foil....duh.

I reset it today and according to the puter it is sh owing better mileage overall, but fillup mileage will tell.

I talk about it on the recently updated blog at https://houseofbugs.com/weblog/?site_id=308

I went to this site https://www.hhomagicgas.com/ and ordered the quick drop system for like 600 bucks it works great 80-100 mpg on my civic it takes very little energy to create hydrogen and when i refer a friend they give me 100 bucks. and i figured out a way to explain it to my friends that your map sensor opens the fuel injectors through increasing and decreasing voltage. your map sensor typically stays at 5v when hydrogen is entered into your car you turn down the volts using the EFIE device so on my volt meter it reads 2.5 volts so its using half the gas on city i get 40 mpg normally i just increased it by double the amount less volts = less gas that is 80mpg city I tried going lower but the engine starts to sputter but when i am on hwy i can turn the map sensor anywhere between 1.8 and 0 volts which at 0 volts means i am not using any gasoline straight hydrogen. all throttle body and fuel injected motors have map sensors and they all are set to 5v. Now I have a civic which is why my gas mileage is so much but the percent in increase is the same for all cars and the hydrogen actually gives me more horsepower according to the dyno i had done. everyone should be doing this EVERYONE!!! there is no tricks just simple math and general car knowledge you can understand why these hydrogen cells are such a big deal.

gto78 08-06-2008 07:14 PM

... LOL

I'm working on a hydrogen generator install myself, already did the Dual EFIE install, now I'm mounting the generator and already mounted up the Pulse Width Modulator. A couple more relays, switches, and an indicator light... can't wait to see some results.

However to be realistic I've never expected more than a couple miles per gallon increase. Knowing that every HHO system is different and produces a different volume of HHO, there's no way of claiming just how much mileage you'll gain- if anything at all. I think the only way of making the engine run on Hydrogen only, and zero gasoline, you'd have to combine about 20 HHO cells, and the amount of current it would use would be so high that the mileage would end up almost the same. It depends on the size of the engine, weight of hte vehicle etc.

If someone just lowers the voltage to an extreme amount on their map sensor or O2 sensor, it just forces the computer into "limp" mode, which turns on the check engine light and eliminates most of the sensors.

Jay2TheRescue 08-06-2008 07:31 PM

The big thing about the HHO systems I keep reading is people modifying the output of the sensors to lean out the engine. Leaning out the engine will increase mileage, whether or not you have an HHO generator hooked up.

I think the only way to truly measure the effectiveness of an HHO system is to run it on a stock non-computer controlled vehicle.

still hearing the same old arguments.....duh...... HHO is easy to make and doesn't take much energy to do it...... if it takes 20 amps from my alternator and costs 1% of gas to do it, but HHO is saving me 20% in gas, I have a 19% free gas bill coming to me....that's free energy no matter how you look at it....oh, don't forget, the nay sayers will point out the fact that youneed to have water to do it and the cost of baking soda....bla bla bla....... same old **** from people who can;t think outside the box.......why don't the auto companies come out with it then....... dum dee dumb dee doodle lee doo, go on home, your mamas calling you.....

listen, auto makers controled by oil, controlled by NY and London exchanges and banksters, controlled by greed, wanting high demand for oil n gas...... and if you don't know that, you just another brainwashed dweeb glued to the freeking idiot box telling you want to think and how to live.......

get a brain!

I guess you need a brain then....LOL

R.I.D.E. 08-08-2008 04:16 AM

Well lets see you claim 1% of fuel will get you 20 amps. I guess that means 100% will get you 2000 amps.

You shouldn't have dropped what brains you had at the curb son, before you climbed down into the gutter to write your "contribution".

Another HHO advocate without a gas log.

Of course your whole post hinges on the word "IF". I prefer facts instead of IFS.

Take whatever mileage you are getting in your vehicle, and realize that I can travel as far on the same number of gallons of gas, as your mileage is, while you have to use 58.77 gallons to travel the same distance.

Lets make it very basic and simple, don't want to overload your brain.
IF your car gets 18 MPG, you need 58.77 gallons of gas to go the same distance I need 18 gallons to travel.

If you think you are making "free" energy, why are you wasting your time writing posts here. You have already created perpetual motion with "free" energy.

You make your own ignorance obvious to any reader.

Some math;

Gasoline has 125,000 BTU per gallon

Hydrogen has 325 BTU per cubic foot

HHO is only 12.5 % hydrogen, so your cubic foot of HHO has only 40 BTU of real energy.

There are 28.3 liters in a cubic foot, so your BTU content for a liter of HHO is slightly under >>>>>>>>>>>>>>>>>>>>>>

1.5 BTU

Thats right ladies and gentlemen 1.5 BTU of real heat energy in a liter of HHO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thats just slightly more energy that you get lighting a wooden match!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You need 83,333 liters of HHO per hour to equal the energy in a gallon of gasoline that my car travels just under 59 miles using that same gallon of gas.

1,388 liters per minute !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!

To get 59 MPG in a civic VX.

At 30 MPG you only need 2729 liters per minute.

I would be willing to wager that any fuel economy improvement is not due to the hydrogen, but to the higher oxygen content of the induced total gas volume.

Snax 08-10-2008 06:47 PM

I'm still one of those people who believe in the potential of HHO injection, but only the sense of it acting like a primer to better ignite the gasoline. Regardless, I have yet to see anybody post a convincing test of this concept to prove it actually works. Until then, I'm choosing to waste my time on other things like the constant wrenching on my motored bike and fixing the flats on the regular ones. :P

I am not out to convince anyone of anything, nor am I out for a quick buck.
You can read the log of my experiences here:

My best was a 30% increase in mileage in town, but in conjunction with water/methanol injection.
