Anyone tried this? The approach is slighly different than meth injection. The theory behind it is that you generate hydrogen onboard from electrolysis of water (electrolyte solution) and use it to supplement your fuel for better mileage, better ignition, etc. Probably a better argument for mileage than power increases as I have not seen any HP comments with HHO yet. So hydrogen versus methanol. That's the question I guess. Perhaps it comes down to cost and yield. With meth, I have seen up to 50/50 ratio on here. With the HHO method you only refill the HHO generator every 1-2 fillups of your tank or even less frequent depending on how much evaporates out. So very little cost--ie some distilled water electrolyte of your choice to fill the unit.

When I first saw it, I thought it was a hoax. But the more I investigate, the more ppl I find already doing it. Just looking for opinions or anyone with experience in the matter.

i have read and talked to people about it,and with a duramax it does not help mpg and it might lower egts. but there are not many benefits with a duramax yet

I wish there was more hard data out there on diesel applications. Most of what I have seen are for gasoline cars and trucks. Although, I have seen kits advertised for semis, tractors and other trucks. Even if you had a beater car, I think it would be worth it to give it a shot and see if you could get that 30%-50% better mileage (and power) they are claiming. Lots of interesting stuff on youtube. Just search for hho.

Electrolysis is a very inefficient means to make hydrogen and oxygen from water. Been used for years in the glass blowing industry. It takes a lot of electricity and the energy taken from the engine is greater then what you get from hydrogen. Only way to get any gains from it is to pump enough juice through the electrodes to boil the water. Gets very hot and you are basically making steam. The mix cools back down in the intake and recollects as water. The water in the combustion chamber then boils or "pop" creating additional cylinder pressure and the old steam engine effect resulting in some gains.

The home made systems are dangerous as there is no flame arrestor. hydrogen gas burns very fast and flame front could propagate back through the gas and to the source generator.

Water-meth injection does the same thing, only the methanol acts as a catalyst for a more complete burn of the diesel fuel. Any hydrogen in the small amounts generated would flash almost instantly having little to no effect on combustion. You would gave to combust a lot for it to have any effect.

110X what Labonte said.

Water injection and water/methanol injection do work. Are proven and work well. The vendors here sell good systems. I have NOT however seen evidence that there is any catalytic effect from methanol burn, nor from Propane or CNG fumigation. In doing the math, it is a straight energy replacement with the energy from burning the methanol, propane or CNG replacing the energy from diesel. No "extra" energy from more complete burning by a catalytic action. (Sorry Labonte). If you can buy the energy equivalent of diesel cheaper with methanol, then it makes a financial case.


But, there is a gain from the phase change of the water from liquid to gas. It adds cylinder pressure (torque) while cooling the EGT's. Both good things. So if you want more power and cooler EGT's it makes sense.

HHO - pure non-sense.

The above is my opinion. You can agree with me and be right or disagree and be wrong. It's still a free country, for now.

there is a write up in my new diesel power magazine. Definatly claiming its not non-sense

I put an HHO system on a 1991 Mitsubishi gas p/u truck I had. The system did produce Hydrogen. but I saw absolutly no MPG gains from it.

Im getting ready to put hydrogen on my lb7, I'll let you know how it goes.

monitoring for more details

did anyone heard anything from nolimit2403? hopefully he's okay and the truck

My thoughts if a hydrogen generator can be built in the back yard for under $100 or $300 for a kit, then WHY wouldn't a multi-billion dollar company mass produce and install them on every vehicle for $50 a pop? Why would they if they would:
1) Increase MPG drastically for vehicles that are under CAFE
2) Increase sales since they get 30 mpg diesel truck while others only get 20 mpg.
3) Reduce pollutants by burring hydrogen and less diesel
4) Add power at the same time as the above. HP and Tq sell vehicles
Wow, GM, Chrysler, BMW, VW, and every other car maker in the WORLD would have hydro generators IF they were effective.
THEY are in the business of making money and selling vehicles. WHY would they not do this? Let’s look at the current reasons they don't make current vehicles do this using diesel or fuel alone:
1) Increase MPG drastically would require massively more efficient vehicles or smaller displacements. This would require billions in research and development passed on to customers. Just use this "proven" hydrogen generators.
2) Increase sales since they get 30 mpg diesel truck while others only get 20 mpg. This would require less HP, smaller displacements, or seriously lightening the vehicle. Once again reducing the vehicle weight, smaller displacement, or reducing HP would hurt sales as people want HP and efficiency.
3) Reduce pollutants by burning hydrogen and less diesel. This requires millions in research and hurts MPG. Look at the diesel particulate systems. Why do all this when a simple $100 hydro generator would solve this?
4) Add power at the same time as the above. HP and Tq sell vehicles. Well, they could easily increase HP by adding more fuel, more boost, more everything, but this would require more expensive turbos, stronger engine parts, worse fuel economy, more pollutants, etc. Why do all that when a $100 "proven" hydrogen generator would work?
IF hydrogen generator is so wonderful, why hasn't it been patented by anyone or an oil company for sure?
IF this simple hydrogen generator works, why wouldn't all car mgf be wildly doing this? Why invest in expensive hydrogen fuel cells?
If it works by liberating more energy in Hydrogen then it consumes to make, why are there no cars that run purely on hydrogen via electrolysis using NO fuel at all? Just run a battery to water and wa-la hydrogen, start vehicle, drive off?
IF this technology was so great, wouldn't the big 3 auto mfg be doing this to save their asses from bankruptcy? Look, new car, 50% better mpg, more power, cleaner burning, etc all for $100 more sticker price. Hummm.
So many questions.....
