Expansion rate of hho ?

[captainl67]

Ok
help me understand . I blew the top off of my electrolyzer to me that would be explosion ! so how far does a liter expand in such a case. and what is pure HHO ?

[captainl67]

 and has anyone seen this implosion ? I have run it in a 25cc engine without any extra air or intake of air so I am thinking explosion. ?
Like I said thow I am not as informed as you guys so please use some laymen terms.

Many have . But because of the shock wave moving outward  you can run a piston engine .. There is still a vacuum effect  but the explosion and shockwave given time to propagate over come this,  driving the piston. This effect will increase with added air. More air will slow the burn time, mainly because of the nitrogen as it is inert. There are many different experiments and devices you can build to see the difference in a vacuum outcome or a expansion outcome  or both. Sealed chambers and inert gas injected chambers such as the piston engine.  There are far to many of these test to list, so here are just a few of the videos we have done. Sorry I am trying to cram far to much in to such a short reply. I hope to explain more as this thread builds.

Pure HHO is derived from the water cracking process.  2 parts hydrogen and 1 part oxygen. This is where the ratio of 66.6% Hydrogen and 33.3% Oxygen comes from . If there is nothing else added to this mix such as air or other we see a stronger implosive effect. This has to do with burn time and propagation. At this mix the burn rate it about 40,000 feet per second .Adding other gases including air will slow this burn rate down. 


"How far does a liter of HHO expand" . this depends on the burn rate and the added air amount or the air that is already in your device. If there is no air or steam or any other gases in the container  the gas will imploded causing the container to destruct inward but as the air comes in through the broken pieces  you then have the explosion effect and this is what you end up seeing as this all happens so fast.

I know some of this sounds contradicting , but there are many factors in this simple gas reaction  and the outcome of  its force.

Well, I've had implosion-explosion events in my HHO experiments. I've seen plastic bubblers collapse from outside air pressure, after an implosion. I've seen cylinder head parts cracked, after explosion. So I think the correct ratio of gases can produce an explosion/shockwave, and then the product of the reaction (water vapor) condenses and produces the implosion effect. In fact, this explosion/implosion is an old-timer's way of getting a partial vacuum in a glass vacuum tube. You fill the tube with water, electrolyse it till the water is displaced by gas, use the pump to evacuate this gas, flame-seal the tube (carefully!) then send a little arc thru the electrodes in the tube to explode/implode the remaining gas. You wind up with a much stronger vacuum than your pump will pull, and a little residual water vapor in the tube.
It would seem to me that a properly-designed IC engine for HHO would take advantage of the explosion, to push the piston down in the normal way, and also the implosion, to pull it partially back up during what would usually be an "exhaust" stroke.
