hho in a small gas engine
I;M REALLY NEW AT THIS AND WANT TO KNOW IF ANYONE HAS ANY INFO ON USING HHO WITH SMALL GAS ENGINES.Sad

RE: hho in a small gas engine
I know this is an old post but check out the book "World Hydrogen View" by Roger Billings. He discusses how to run engines on hydrogen, so should be comparable to HHO, just need to take extra oxygen into account when determining A/F Ratios. I learned a lot from reading the book. For example you can run a hydrogen fueled engine at 17 deg. BTC with no backflashing and low oxides of nitrogen emissions as long as you use supplemental water injection at the correct direct proportion to the amount of hydrogen admitted. This would be of particular advantage for small single cylinder engines, since the waste spark should no longer be a problem with the timing set before top dead center. Common knowledge says that you have to set the timing to ATC, I believe, but apparently THIS IS NOT NECESSARILY CORRECT!. Another thing that may be advantageous would be to reduce the spark plug gap, so the firing voltage of the plug is lowered. Hydrogen ignites at a much higher temperature than gasoline, but it also ignites with much less energy required for ignition ! We need to increase the octane, which is the same as slowing down the burn of the hydrogen. This is the purpose of the water injection. A stratified charge can be helpful in this regard also, but that is really only accomplished through direct cylinder injection, which is much more difficult to do than gas carburetion. Another advantage of direct cylinder injection is that the cylinder can be packed with high pressure hydrogen which effectively turbocharges the engine, with the result that the hydrogen engine can then actually produce more horsepower than the normally aspirated gasoline engine. There is lots of other info. in the book, check it out.

He has a couple of websites with some historical info, 5 chapters of book are available as free PDF files on website:

http://rogerbillings.info/index.html

Also you can check out Roy McAllister videos (some are available on YouTube). I think he has written some books and videos that are available through http://www.knowledgepublications.com/ and amazon.com. He may be just referring to hydrogen as well, but should be somewhat applicable to HHO.

The big problem, I think, with running on HHO is that it is generally not considered very safe to store it, since it has the oxidizer already present. Because you have to produce it on demand, it is more difficult to produce enough to allow acceleration under heavy load conditions, even for a small engine, but I believe it is possible with the right supply driver circuitry and pressure regulation and gas carburetion. Stationary engines that run at a fixed speed and load would be much easier. Overunity production through resonance techniques (if you can pull it off) would definitely be helpful!

Hope this helps. If you have more specific questions just ask, not sure I'll have the answer but maybe someone else will.

P.S. If anyone else knows of any other good information sources for running small gas engines on HHO please come forward. I think this thread should be more active.

RE: hho in a small gas engine
Tero Ranta discusses the difficulties of running a small engine on HHO gas alone in his pdf file:

It seems that either you must store the gas, which is very dangerous, or you need some method of overunity production. Zach West's electrolyzer may be accomplishing this overunity production?

See http://www.free-energy-info.co.uk/Chapter10.pdf pp 62 - 77

Also Bob Boyce is said to have accomplished this overunity production as have Dave Lawton and Ravi Raju. So it just may be possible, hopefully time will tell.
