J. Kleban!
If you have "competitive" and reliable data, I'd love to know it.
I don't see the error you're talking about:

I do not know how this sentence may suggest that the engine cooling causes a decrease in its efficiency. This is some new, unknown theory? Did you dump the radiator in your Maybach and it started to drive like a Ferrari?
You write that thermal energy is only part of the engine's energy. How big part? Where does "rest" energy come from? Is it possible to run the engine with this "rest" without fuel? That would be a brand new Perpetuum Mobile! So far, scammers or fools have the sole share in promoting "PM", maybe you will finally make a breakthrough?
Why do you think detonation combustion gives more power if all engine and fuel manufacturers are trying to optimize both fuels and engines so that detonation combustion does not occur? Do you know a secret of fuels and engines that is unknown to their manufacturers? Or is it another unknown new theory?
If you know what explosives get their strength from, why not share this knowledge as well? I read somewhere that the energy that can be obtained from burning 1 kg of coal is several times greater than from 1 kg of dynamite!
I searched, found: coal - 27MJ / kg, and dynamite 3MJ / kg - comes out 9 times ...
However, if your "revelations" do not have any basis in documented knowledge, and are only your guesswork, then do not let people raspberries, as this is an offense against the Electrode Regulations.
