some of theories I have read suggest 1/3 of the combustion energy ends up in the radiator, 1/3 ends up out the exhaust, and 1/3 makes the car "go forward."
When you dig a bit deeper, you discover the 33 percent to make the car go forward is VASTLY exagerated - 25 percent is a more reasonable goal.
It seems to me the energy going out the radiator is an opportunity for better mileage.
It seems to me if I can reduce the combustion temps, I will lose less energy to the radiator.
It seems to me if steam is HALF as efficient as the adiabatic process, but I lower the combustion temp in half while doing it, I am still ahead. After all, the radiator gets more energy then propulsion does by a fair amount.
