i was talking with a guy i go to school with that has a little background in electronics/electrical stuff he was telling me and showing me videos about the electrolysis process and how it can theoretically improve MPG of both gas and diesel engines by using hydrogen gas. have any of you guys ever heard of this? is anyone using it??? ive done a little research on it and have found that it is best to use on older vehicles without computer management systems.... "cough cough the IDI"......... im really interested in this but need a little more sound info on it.... i know the gas produced by the electrolysis process is flammable I saw that in the guys videos he made in his garage. the only thing im wondering about really is the volume of the gas required to make it efficient. he said he's got about 50 bucks in it so far making his.... its not on a vehicle yet its still in his testing phase.... if this is something that could drastically improve our MPG with nothing but positive effects it might be worth looking into right? there is just so much BS on the internet about it that people seem to be putting it down but i do have to believe the oil companies have a hand in silencing this move away from traditional fuels.....

 

Don't waste your time or money....Someone tried to sell my boss on the same idea. Tried to tell him it was a line of B.S., but, to make a long story short, it didn't help.
First, the volume required would be immense, just to even noticeable improve mileage....Second, it would pre-ignite when the piston begins to compress the air and before the fuel injector injects the diesel fuel.

 

now that i don't think is right.... i know it takes a spark to ignite. the spark in the case of diesel would be when the diesel fuel ignites. i know hydrogen gas is stored under pressure in tanks so it doesn't ignite under pressure alone

i know that you can run a gas engine on hydrogen just like you can run it on LP or CNG. you can however autoignight hydrogen the same way diesel dose when its compressed to a point that the heat it generates will set it off. i however would not want to haul hydrogen around with me in my truck. hydrogen is a diffrent type of animal to work with. we make and use hydrogen gas at the refinary, ive seen it do some things...lol

 

Don't believe the HHO scam, because that's all it is. Electrolysis is the most inefficient method we have to produce hydrogen. You can't possibly produce enough gas on a typical vehicle electrical circuit of 15-40 amps to even make a dent in mileage. It's physically impossible.

And hydrogen fuel cell technology is a completely different animal.

 

The doubtful bit in this is that the energy balance makes no sense. It takes energy to make energy! Electrolysis increases load on your alternator, increasing resistance to the belt turning, demanding more throttle input. You can't make energy out of nothing; you're not adding any more energy to the system, so it can't help you.

Even on the most basic level, you're expending enough energy to split Hydrogen and Oxygen apart, then, the absolute maximum energy you could get back would be combusting Hydrogen to its most stable product, H2O, which is where you started, leaving no net gain in energy. Add in that a fraction of it will burn with the fuel and produce more complex products of combustion (which produces less energy) and the electrical losses converting 12v to a lower voltage / higher current supply needed for a decent electrolysis rate and you're now loosing energy.

Also, Hydrogen will likely ignite on compression in a diesel. As noted, not just on the compression alone, but with the heat as well. For reference, Hydrogen gas is EXTREMELY flammable, and more explosive than propane or methane, among others. It is in fact almost as explosive as Acetylene.

Hydrogen injection DOES benefit if you make it before-hand, since electricity in your house is cheaper energy that fuel in your truck! Just think if you want to be manufacturing something nearly as hazardous as Acetylene...

 

right remember you never get something for nothing, energy in will never equal energy out due to losses to inefficendies and nothing will ever be 100%efficent, its physicaly impossible. we make hydrogen from natural gas at the refinary, its a big ol process to make something that we can use and its a pretty delicate operation. hydrogen is very flammible, and it really dose burn with an almost invisable flame. the only way to see a hydrogen fire at work is to look for the pipeing and i beams starting to melt.

 

This is what I was going to say. Impossible to get any benefit unless you have free energy. I would not use it in diesel engine if it was free.

Your friend at school needs to take basic physics over, he flunked the first time. Amazing how many people will get taken by this hydrogen-from-water BS scam as gas prices rise further.

 

everyone has ideas, the trick is comming up with practical ideas. if they want us off of oil, there gunna have to come up a real practical alternitave. something that they havent come up with yet

 

if you want that water to do better things for you, you'll be better off injecting it as water!! it seems this was quite popular back in the 70s, based on the FACT that when the water is exposed to that heat, the steam it produces serves to greatly increase combustion pressures and reduce combustion temps (which in a gasser allows a leaner fuel/air mix, etc)... i'm not sure how practical it would be in a diesel, but would be a more sensible project than hydrogen

 

people do use water injection on diesels, gotta be real careful setting that up though, too much water and youll blow the heads right off the block

 

For what it's worth I"ve used the HHO setup and it does work. It takes some work but it does work. I'll agree there are some scams out there but if you do it right you'll come out ahead. BTW, I"ve got a 1987 F250 with a 6.9 n/a. Now about that water injection........
