An auto fuel injector would provide the right amount of fuel

I like your pioneer spirit Alex. Keep in mind If OA is too powerful acetylene and air can be used. Also MAPP gas, butane or whichever is easier to get. While we're brainstorming, I wonder how an automotive fuel injector and gasoline might work (this would of course be used with a steel chamber and b...

Using pressurized air you'd be able to fire rapidly. We assume the incoming charge would blow the exhaust gasses out the barrel. Car engines use air and this is basically a similarly fuel injected cylinder without a piston.

Rambo, if you look at the first post in this topic you'll see a diagram for just what you mentioned - my design uses solenoid operated fill and purge (exhaust) valves and an electronic ignition system which accomplish pretty much what your pic describes. BTW this could also be adapted for use with e...

You can thank me later for all the lively discussion my post started :) Strangely, despite the fact that "equations are plastered all over the internet" and "theres <sp> members here that know there crap when it comes to physics" no one's posted anything here to positively support that position and ...

I certainly wouldn't have posted what I did without knowing I'd get all types of replies - that's part of the fun of public forums. Thanks for the vote of confidence. This isn't NASA so no one can predict the outcome of what I suggested with any accuracy. That doesn't mean go ahead and do it without...

No really let's hear how you really feel :) Under the right conditions any combustible gas detonates. And yes PVC isn't the same material as in an engine so it's probably overkill to say the least (pun intended) That said the general idea was to get a better gas/air ratio for better performance. Usi...

Has anyone used Oxy Acetylene as a fuel for cannons? It's perfectly mixed, pressurized and has a LOT more energy per cu in than propane. Yes I am aware of the potential danger, but with the proper safeguards in place it should work a heck of a lot better. Attached is the wiring diagram for one I'm t...
