what engines are capable to run 100% on hho, h2, hydrogen gas for vehicles?

Is there ideal engines for the conversion? I want to construct a van that holds enough hydrogen to operate 200 miles power day ++ and cover it with solar panels & a bracket to hold a1,500 watt windmill. Ideally,I would use an AC outlet to produce the hydrogen but with added options to make its own too. This is the ultimate bug out vehicle. I will probably wonder off into the wilderness forever once its complete.

Answer
Sounds like an interesting project. There are some car companies that make hydrogen internal combustion engines/cars but they are hugely expensive and conversions from gas to hydrogen has some problems. A propane engine design might be suitable for adaptation to hydrogen. The fuel/air mixture is much different for hydrogen requiring special carbs and engine timing changes and hydrogen embrittlement of engine parts or exhaust can lower engine life and other parts.
Storing hydrogen is another issue as it requires a large volume of gas under very high pressures to have a suitable range you're looking for.....special tanks, lines, valves, refueling, etc..

There are some new methods coming out to make on-demand low pressure hydrogen gas using chemical processes like sodium silicides or cobalt catalysts which could alleviate some of the problems with onboard storage/use. You can also make hydrogen from urine which has twice the hydrogen molecules as water and splits apart in electrolysis at lower voltages..

Chinese Jonway Scooter 50cc backfired and won't start?

Mike

I have a 2012 Jonway 50cc Chinese Scooter and just hit 1300 miles. I was having battery issues and was relying on the kickstarter. I was riding in the rain and was having some issues with the idling and it stalled. I kickstarted and got it up and running again when finally I heard a sound that sounded like fluid and was followed closely by a gunshot-like sound. The electricity gave out, lights, instrumentation, etc. and it would not start back up again and I was luckily close enough to walk the bike home.

I tried jump-starting it today and it did not want to turn over with the kick starter or electric starter. I had no sound whatsoever out of the electric starter where usually I will hear it trying to start. Also the spark plug was apparently loose, but I rettached it although the bronze or gold tip that sits in the ignition wire is missing the clip and it is not sitting tightly although there was definitely contact and it should have started up.

Any help would be appreciated as I rely on this for transportation and am just wondering what the list of parts to get would be.

Thanks!
Also the person that I purchased from had removed the "restrictor plate" which I believe was a restrictor tube that sits in the air intake case because there is no tube inside there. Apparently this can cause backfiring and all sorts of problems because there is a disproportionate amount of air going in to the engine.
I can get a whole new engine for about $200 on this so if that can save on labor I'd just drop a new one in there.
Thank you for the detailed answer, what I mean by not turning over is that the electric starter will not click whatsoever but the kickstarter will move and it sounds the way a lawnmower does that won't start when you can pull the cord but it won't start...

Answer
You should at least hear a click or something from the starter. What is your definition of turn over? Do you mean that the engine spins but does not fire. Or do you mean that the engine is completely locked? You can not move the kick starter and all the electric start does is click.

If the engine spins but does not start it could be any number of things. You say the gold cap is missing from the spark plug. What happens if you remove the spark plug, put it back on the wire, lay it on a metal piece of the engine, and spin the engine over? There should be a strong bluish white spark between the electrodes. No spark and the engine will not run. You may just simply need a new spark plug.

You should never ever jump start a scooter or motorcycle. Bad things can happen. It is very easy to fry the ignition system when you jump start. If the ignition box is fried the spark plug gets no spark. No spark and there is no way the engine will start.

If the engine is locked, you have some serious internal mechanical issues. You may want to look into that new engine.

You mention the disproportionate amount of air entering the engine. This is technically called running the engine lean. This is bad. Then the person removed this restrictor tube, he should have installed a larger main fuel jet in the carburetor. When the engine runs lean it can literally burn a hole in the piston. Molten metal can seize the piston rings to the cylinder wall. If this is what happened, look into that new engine.

The backfire could also cause the camshaft to jump time. However, there are usually other mechanical issues that go along with this.
