Well, to be fair, you are cooling more than the exhaust. Both the Crower Six-Stroke (2006) and the Dyer Six-Stroke (1915) were able to run without a cooling system as well

In reference to your above argument, the energy that converts the water to steam comes from the piston/valves/chamber/etc, not just the exhaust air. The problem is that extracting the heat from there just increases the delta-T between the combustion and chamber walls (and therefore heat transfer) on the next power stroke, effectively weakening it.

There is probably a reason Crower never finished his patent application, and why Dyer's engine never went anywhere 100 years ago.
