you wouldnt be able to store very much unless you had a compressor of some sort

Ugh... I told you guys I'll even plug the cord in the house to make the electrolisys i do not freakin care, i just want to see if the motor will run on the h2 that i make from electrolisys(sp)

you will ned to store it. th consumption of th engin can't b supplmntd just by on the fly electrolosis., you nd to hav a storage spac

If your going to store the hydrogen make sure that you separate it from the oxygen in the process of electrolysis. This way it won't be as likely to explode if it was lit. To keep the hydrogen isolated you will need to use DC current. The hydrogen will come off of the negative electrode. I heard somewhere where they used high voltage pulses to conduct a lower voltage current through the water, it requires less electricity and makes more hydrogen. i don't know if this really works though

You can very easily make an engine to run on hydrogen. What you need is a compressed source of H, and a simple fuel injector. Gut the carb so all you have is the throttle plate. Grab a fuel injector designed for propane and connect it to your hydrogen regulator. Make a PWM circuit to give the injector pusles based on engine vacuum (measure after throttle plate with any standard GM style MAP sensor). One hydrogen engine. Simple.

You need the circuit to control the injection amount/rate of hydrogen. I suppose you could try to rig up a mechanical timing system rather than an electronic one, but I wouldn't try it.

Should work fine for all basic gas engines. You need the PWM circuit to control your fuel injection and keep the mixture correct. Just putting a regulator directly to the carb will allow the engine to run if you manually adjust the mixture, but you don't want to do this. You would have to make adjustments any time the load or speed of the engine changes, as well as compensate for temperature, etc. A simple PWM based on three outside inputs (vacuum signal, RPM of engine, throttle position) is easy, and there are probably ICs already around to do this.
But again, there's the "why?" factor. Seems to be an aweful lot of trouble to go through to make an already inefficient engine less efficient, with a fuel that is difficult to obtain.

"why" has been awsered. to se if it can be dome and too kep urself occupied. if you hav to ask, youll never know.

True, but when I do a project, I like to have a usable result. A hydrogen lawnmower engine is neat, but won't have enough power to mow the lawn, and refuelling it will be annoying. Instead, why not buy or build a fuel cell?

it is much too efficent. and how csn u build one?
at last!!! |

Aren't those membrains expensive, plus the controlling mechanism would be critical...

There are a number of homade fuel cell plans on the Net, as well as kits. Alot simpler them most people assume...

OK here goes- 1) Im not into precision when it comes to stupid projects..... 2) there is a way to produce a LOT of hydrogen through a chemical reaction between caustic soda(dont want to get any on your hands tho! lol) and strips of aluminum here you guys check out this site:
http://www.fortunecity.com/greenfield/bp/16/jacksongas.htm
i want to make a simpler version of that; larger metal container filled with aluminum strips and then quickly with caustic soda/water and closed with a lid that contains a tube equiped with a one-way :) valve which goes to a simple valve to regulate gas flow which in turn goes into the intake pipe for the lawnmower(where the card should be) and hopefully ill still be able to walk the next day
