temp and efficiency

The only relationship that I know of,is raising the temp in the combustion process with high-temp metalurgy or ceramics such that the delta-T is actually increased and waste heat eliminated.An adiabatic cycle.No cooling system.
Experimental engines have been tested.Nitrogen oxides were an issue at temps where 'inert' gases begin to react.
Vapor-phase or dry lubrication is also of interest.
Be careful.
