/diy/ - Do It Yourself

fuel cell technology is expensive, not diy. You're better off with electricity.

all i am talking about is to assist the combustion of the gasoline by installing a very simple hho generator, not full hydrogen powered just a little help.

>>418510

then no, hydrolysis is not a suitable source of free energy, it takes energy to split the water molecule, quite a bit of energy that has to come from somewhere.

>>418510
hydrogen gas?
yea why not. its not different from any other combustible gas.
Lots of cars run on propane just fine.
Theres even car out there that run on water but the government is keeping it under wraps because it will destroy the economy.
how are you gonna seperate the H from watteR?

>>418512
all i am asking is if the hydrogen will assist the gasoline. Not whether it is energy efficient. Trust me a car battery in a running car will do just fine.

>>418512

electrolysis

>>418515

Depends on the engine, you will be running richer, increasing compression, if you could re-tune the engine, more fuel is always better.

>>418518
how would compression be effected at all?

>>418505
I would say no, OP, because in normal operation your intake is likely not delivering enough oxygen to burn all the normal fuel unless you have a turbo or supercharger. Just adding hydrogen will just result in more unburned fuel leaving your tail pipe and the water produced is detrimental to your engine. Reacting with your exhaust this will likely result in sulfuric acid or some such going through your cylinders on out.

You're better off consulting your owners manual or the makers website on the most fuel efficient way(speed) to drive your car. No magic fuel will increase your fuel efficiency.

electrolysis produces hydrogen and oxygen so both will be added to the intake also if the first o2 censer is detecting to much fumes then it will lessen the amount of gasoline being injected.

Let me tell you a secret about life anon. If it was simple and cheap it would be every where. Any "amazing" idea you have isn't amazing, 99.9999% of the time its infeasible and/or retarded. Also, things are never as simple as you would love to believe.

This should be at the top of the /diy/ Page, honestly.

>>418551
Unless you have a power source other than the engine for this you are working in diminishing returns. Internal combustion engines are notoriously inefficient in converting chemical to mechanical power.

There are actual setups that run on pure hydrogen and atmospheric oxygen. The hydrogen being supplied by solar based electrolysis most of the time. But by all means, go right ahead.

>>418505
If you don't know what you're doing, you should do research beforehand. Engines are designed for fuels from the pump, if you add a different mixture you will get unpredictable results.

>>418569
actually engines are not designed for a specific type of fuel the only thing that changes is the programming.

>>418569
>what is propane conversion kit

>>418505
>so here is my question, if i were to directly add hydrogen gas into my intake manifold on my car would this give me a boost in gas millage?
someone else already said it, but no.

adding hydrogen won't increase the energy density of the gasoline, in fact it would *lower* the density,,,, because hydrogen is less energy-dense than gasoline.

To get greater energy density, you would need to use heavier (longer) hydrocarbon chains,,,, like--diesel fuel. Or fuel oil. Or motor oil. But guess what? A normal gasoline piston engine isn't going to last long burning fuel that is much-higher-density than the gasoline it was designed for. The fixed compression ratio would need to be adjustable.

>>418608
but it would replace some of the gasoline wont it. it will not make the gas perform better it will just make the engine not use as much gasoline.

There is this scam device that does this. Hook it up to your battery and connect it into the air intake. Put simply it doesn't work because there isn't enough hydrogen made to effect gas mileage. Especially obvious when they claim that you double gas mileage.

If you use the battery to get hydrogen and then burn it to get mechanical energy, which will then move the alternator and charge the battery ... well this is not a perpetual motion machine. You are loosing energy in this loop.

>>418930

Worse than that, you aren't gaining any energy.
You're just blowing yo juice.

>>418618

No,the engine will continue to use as much gas as it did before. It's just the air/fuel ratio will be off,making it run less efficiently.

Maybe even cause other problems,like misfires.

big rigs use h20 systems but they only get a 5-10% boost in mileage (which works for them.) works better with diesel. google it.

you can do it with a smaller car but the increased alternator usage will kill the efficiency. you would have to mess with the fuel/air mixture as well.

>>418505

Nah, wont help. If you plan on generating the hydrogen on the fly you will make so little hydrogen that it will do nothing to your mileage. In fact, if you are in any way using the battery or engine to power your hydrogen generator it will lower your gas mileage. Whether you power it from the motor directly or the battery you will be burning extra gas to get your hydrogen which will in turn do nothing for your mileage.

Now, if you have a pre-charged tank of hydrogen stashed in the car somewhere are you release some of that into the air intake.. you will still lower your gas mileage. The hydrogen will burn but it will fuck with your air/fuel mixture. Without the proper amount of oxygen to fuel the combustion your engine will run less efficiently and probably cause the computer to do funny things with your air/fuel mix to try and correct the unexpected conditions its experiencing.

Now, you could completely replace the fuel with hydrogen if you wanted. The engine would run, but hydrogen is not a good replacement for an engine that was designed for gasoline. Same deal with propane and other "gas" conversions. They work, but not as well as an engine designed for it from the start. Still, if you have a cheap source of hydrogen, propane, whatever, it might be worth your while to look into.

do it tom ogle. go ahead

>same GMderi

nice thought, but the problem with hydrogen is storing and carrying it.
bascially a bomb.
remember the Hindenburg?

>>418930
do you even grasp the concept of perpetual motion you idiot it would be perpetual if there was no type of gas wether it be gasoline or hydrogen there is still a resource being used please dont comment

>>419485
fail post
>do you even grasp the concept of perpetual motion?

Do you?

>>419495
looks like someones butt hurt that they have no real contribution to this topic.

>>418930
>>419495
So is a oil pump that is powered by gasoline perpetual motion???? No because there is a fuel being burned. The thing that you fail to realize is that im not pulling the hydrogen out of my ass, i am taking it out of water, witch in this case is used as a fuel. And to spin the engine that moves the alternator is gasoline so please leave this post.

thanks for contributing

xD

>>419816
wy thank you i actually am contributing because im op so fuck off.

>>418515
>lemme just break the first law of thermodynamcs
no op, it will just just make it pump out carbon monoxide due to lack of oxygen

>>419821
another contribution
>thanks

Extra hydrogen will decrease the carbon monoxide output, instead giving CO2 and water. This means more power from your fuel.

My uncle has this on his vehicle. He is a former mechanic from a family of mechanics, and claims that it works. As a chemist, I can see where it COULD work, depending on how efficient your cracking process was, and the proportion of H2 added to the combustion.

Hydrogen is fine if you are sitting on a source of geothermal energy, otherwise hydrogen is not cost effective no matter what as it has to be produced.
For the engine, a gas engine is optimized for gas and anything else you feed it with will reduce performance and efficiency.
So unless you're going to spend a lot of money on this rebuilding and tuning the engine (plus fuel system, hydrogen is the leakiest stuff on earth) then it is a definitive no.
And a few more no's.
And even some more no's.
