One solution is to provide a replacement to the N2 gas that makes up 79% of our air...

That is where water injection comes in. A small volume of water, directly injected into the combustion chamber pre-ignition point will flash into a large volume of steam providing the buffering gas and the pressure producing gas.
I didn't think about using purely water injection, but that might work.

My original idea is to cool nearly all the exhaust and reroute that back into the intake and use some of the condensated water from it for some water injection.
