Hahaha well It is a little experiment,which I am sure has been tried before.Here is a lil low down:
The wankel rotary engine I will be using contains 4 fuel injectors for 2 chambers(2 injectors per cahmber).But since the fuel is injected in the intake manifold,I will move the injectors into the intake chamber for direct inject so I can use h2 as fuel.I will have to use direct injection since h2 is lighter than air.But instead of just running straight h2, I wanted to shoot a small amount of h2 along with water into the intake chamber,which will then compress and detonate the hydrogen,causing thermal water splitting(hopefully lol).Newayz that is it.But I wont be attempting this experiment for another few months since I have to rebuild/learn more about the engine I am using.Thanks for the info!
