The theory seem sound, regular gasoline engines are fully capable of running on pure hydrogen. The only modification needed is a dry carb, or fuel injectors capable of injecting gases instead of liquids and maybe a little engine tuning. There are many piston vehicles that run on hydrogen and the great part is the only emissions it gives off is Pure Distilled Water.

I'm personally a huge supporter of Hydrogen powered vehicles whether it be fuel cells or piston powered. The only thing needed is the infrastructure of hydrogen fill stations, otherwise hydrogen is very easy to make from water and if renewable resources like wind or solar energy is used to make it, it is virtually pollution free.

I saw a 500hp Shelby Colbra at a car show once that ran on pure hydrogen...it was pretty freakin sweet but it goes to show power wont drop if we make the switch to hydrogen.

 

i know on youtube somewhere. acetone will increase your mileage like 10 mpg better.

i have never tried it, but there is a engineer i know that swears by it

Cheers

No it won't. It may increase it slightly at the expense of eating all of the rubber compnents on you fuel system.

It does make a great fuel system cleaner. So I guess if your driving a Prius with a really dirty fuel system a 10 mpg jump would be possible*.

The hydrogen system is interesting. I guess nothing would be out of the question once she's paid off and the gas prices continue to climb.

edit: Just think, for $700 I can get a 20% increase in fuel efficiency and actually get to the 20mpg the EPA sticker said when I bought the truck!

 

Interesting theory, but what controls the output of the HHO? It doesn't make much sense to just dump it in at a constant rate regardless of throttle position or engine load. Try one and post up your results, who knows, might work.

 

This sounds pretty interesting. I'd like to see the theory behind it.
From what the website says.
the added hydrogen + oxygen to the air intake makes the fuel burn faster so you get more complete combustion which is what gives you the better fuel efficiency

Practically zero chance this could work. Any power/mileage gains would be offset by the engine having to work harder turning the alternator.

I highly doubt that as the power it actually takes to run this unit is next to nil. The fact that the engineer i know that installed one saves almost 100kms per tank tells me it does work. The debate here is, is there any damage goning to be done to the motor in the long run and how does this thing account for an engine working harder or under cruise as it consistently add's the same amount of gas, essenually boosting octane. Most guys on here drop 300$ for an air intake that may put an extra 3 hp at the crank when this device claims 15% increase in mileage at the least.

 

He he!

It's using the gasoline engine to run the alternator to generate electricity to split water into hydrogen and oxygen, then burning the hydrogen in the same engine to remake water. If this was 100% efficient, you'd still be out the power it took to cart the extra weight around. (If it were magically >100% efficient, we'd all have these perpetual motion machines doing everything for us...)

Now if you could generate the electricity with a big solar array or wind turbine, you might be ahead. Particularly if you could generate the stuff when you were parked. But compare the output of solar cells (or worse, wind turbines) to the power required to move a car. Then there's the issue of storage. Hydrogen, as the smallest molecule, leaks through everything. Even the metal walls of pipes. There will be challenges getting to that utopian hydrogen economy.

 

You sir know your shit.

I've read that the best solution right now is to use a tank set up full of hydrides. This allows for a near doubling of capacity for storage. However it doesn't address the issue of the hydrogen "leaking" through the pours of the metal tank.


What we need is transparent aluminum to save the day!

 

This is not a fuel cell so there would be no issue with the hydrogen storage or hydrogen fueling stations

It converts distilled water through electrolysis into hydrogen and oxygen which is dumped into the air intake.

The hydrogen makes the A/F mixture burn faster and more complete. The extra oxygen increases the octane rating.

Extra strain on the alternator, probably yes
Better MPG, I think it would

 

Interesting.... For the sake of argument, I get around 18mpg... An additional 15% would be an extra 2.7mpg. Assuming I fill up around 18 gallons (normal for me), that's an extra 48.6 miles per tank....

So how long would this thing take to pay for itself assuming it works as claimed? (just wondering if it's even WORTH it IF it works....)

Also assuming the $347model (AL-30 good for 373 miles) would be the right one for our trucks.

I just can't do the math tonight! :lol:

Excel and I are old friends. Without laying it all out it would take about 33 complete fillups to pay for itself assuming $3.50/gal on the gas cost.

 

How much strain would this put on the alt anyway? It's connected to the battery so unless it drains the battery rapidly I can't see it affecting things more than headlights, fog lights, amps, etc. Certainly not as much as the 1000W amps some people put in their trucks, or 100W off road lights.

 

How cool is this? Let's get one of those pure hydrogen engines and hook up our alternator and power one of these little bad boys to produce the hydrogen to feed the engine to produce the electricity to create the hydrogen to power the engine. Hell we don't even need the gasoline part anymore. Ok so maybe it's not powerful enough for a whole truck but maybe a skate board or we could make a really big one or we could just put a whole bunch together and use some of the "extra" electricity to power our homes. Cool. </sarcasm>

 

I was looking into this a bit further and found some more material here

Loads of info, some quality, some BS
And info for DIY, might be an interesting experiment/project

 

If only i was still driving my 1990 mercury topaz.(pimp'd) i'd install one of these as se how she went. Unfortunatly i'm not willing to risk the new truck although i've looked into this pretty extensivly at school all day bored out of my mind and it does look reasonable.

I like how some of these comments believe this is a 500$ convert your vehicle over to hydrogen device. There actually quite small, use little power from your bat but do need to be filled up with water and some use a sodium solution every tank or two.

 

This thread got me to researching this whole HHO generator thing, and I built one. It draws about 10 amps and puts out around 1 liter a minute when it's warmed up. It cost a whopping $1.79 to build, I used an old coleman air pump (you know, the kind you use for blow up dolls) and some 1/2" SS tubing I had laying around. I gutted the pump and arranged the tubing around the center tube that attaches to the pump handle, the only thing I spent money on was the BBQ skewers I used as anodes. Works pretty slick, so far all I have done is blow up a couple pop bottles, but I'm going to run the HHO into the filter in my volant airbox and see what happens. I can watch my fuel trims on my laptop and the A/F ratio on my wideband, so no worries about blowing the motor up. Besides, all I'm doing is adding more fuel. The worst that will happen is it will run rich. HHO is 3 times more powerful than gas, so my one liter a minute is equal to 3 L of gas a minute. Probably barely enough to idle the thirsty 4.0, but we'll see. I'll take some pics when I get it under the hood, right now it's just an air pump with wires coming out the top.

 

:clap: I'll be anxiously awaiting results and pics!

 

I want to build one too. Have done a lot of reading on it
If you end up putting it into your air intake the EFI controller will try to make your A/F ratio rich because the HHO burns most of the fuel that is usually catalyzed in the cats from incomplete combustion.
You'll have to override this to make it run leaner to see the improved mpg
Good luck

 

Nah. In closed loop when the ECU is using feedback from the o2 sensors it will see the extra fuel getting dumped in (hho) and the fuel trims will go negative as the ECU pulls the fuel (gasoline) out. Open loop is a different story, on our truck anything above 3000 rpms relies on a preset map that changes the amount of fuel based on temperature (engine and ambient), throttle positon, and engine load. Tuning open loop might not hurt, but honestly there isn't enough volume to make a shit one way or another at 3000 rpms and above. HHO is just a drop in the bucket, but it's a free drop so I'm going to try it. Some try to throw the fact that you are also producing oxygen which may get read weird by the o2 sensor, but that's bs because it will get burnt up and by the time it gets to the cats it will be water again, so no worries there. Oh and the exhaust hits the first set of o2 sensors BEFORE the first cat, those sensors are used by the ECU to tune fuel trims, the second set of sensors after the first cat is just to make sure the cat is functioning, there's no tuning feedback from them at all.

 

I'm glad you understood WTF you just said! Might as well be another drunken ramble to me! Maybe if I read it again later it will make more sense. I don't understand that stuff. :lol:

 

I did some reading, and I guess you are right. For whatever reason, when the HHO is introduced to the combustion chamber it leans the A/F out and the o2 sensors pick up on that and add more fuel. I also did some more electrolyte tests today with vinegar 50/50 with tap water and the results were kind of interesting. At first, it only drew 6 amps with very little output. After about an hour, it stopped producing any gas at all. I thought I had a leak, but pressure testing proved I did not, so out of boredome I swapped the anode and cathode polarity and bam, more gas than I knew what to do with. After the cell warmed up I switched the polarity back to normal and gas production continued at an astonishing rate. I estimate 2-3LPM, but I didn't have any way to test large quantities so I'm not certain. At peak temp and output it was drawing about 30 amps. the problem was the gas bubbles foamed up a lot, overflowing my flashback bubbler and a second 1 liter water bottle in half a minute or so, so I had to shut it down. I planned on doing a test run on the truck today, but with the huge amounts of gas and foam over I am redesigning the system to a closed cell design with a reservoir, just need to find parts. I'm also thinking of building a PWM to keep the draw minimal, hooked direct to a batt there is just no way to control this monster.

 

I've been doing more testing off and on... I left it running all night with a temperature probe installed to see how hot it would get, and it looked like a grenade went off in the shop the next morning. I'm not sure what happened, but it must have been a tremendous kaboom. I'm suprised it didn't wake me up, but the windows were still there so it wasn't too bad. For my new cell I'm doing a plate design in a small 1 liter bottle. I've got some pretty impressive results running 110VAC out of a 760W inverter and that's what I plan on using for power for this one. I spent about $30 on parts, so hopefully it turns out better than the last one. Still having problems with the eloctrolyte foaming...tried vinegar and distilled water, water and baking soda, and just plain old water. The plain water didn't work, no HHO output at all. Hmm.

 

Yikes,
Is it foaming because of high HHO production or is it a chemical reaction within the electrolyte itself.
Have you tried a sodium hydroxide solution yet?

 

next up, Tacogrande's truck develops wings and rocket propulsion!

 

I totally forgot about this thread. I'm not exactly sure what caused the foam, but I think it was a severe PH imbalance due to too much baking soda. I ended up going with a plate system, then found some SS aircraft cable so went with a helix design, then back to plates, then changed my cell design completely again, and now I'm moving so I get to start all over on the other side of the pond.

 

any updates on this?
