quote: I am doing electrolysis on water and it is producing hydrogen and oxygen. What is the hydrogen/oxygen injection mentioned on the home page.
I'm not sure what you mean. Can you provide a link?

I did that by accident several years ago by adding salt to increase the conductivity of water (speed the reaction). Very bad. As you probably know, chlorine is very poisonous and a major irritant to the lungs, nose and eyes.
Can anyone explain the combustion method of injecting hydrogen and oxygen? and can you use Hydrogen + oxygen mixed in a PVC gun or must a metal one be made?
Well, that was just sort of a general mention,w ithout any specifics. But I assume that the writer meant to use a source of pressurized H and O. You would then connect the tanks to a set of jets installed into your combustion chamber. Nitrous jets for cars might work, though the bore will be a little large.
Doubtfull that a metal gun is absolutely required, though it's a good idea when using any external oxidizer.
