But then, if you cool the cylinder down, doesn't the next cycle lose
efficiency in the gasoline portion of the cycle?

Good question. Does anyone here know what the optimum cylinder
temperature is for gasiline combustion?

In a sense, this system is replacing the normal water cooling system
and the amount of water injected could vary to provide the proper
cylinder temperature, within limits.

You could use one or more temperature sensors on the head to control
the amount of water injected and the degree of cooling (no pun
intended). You'd probably want the temp. sensors anyway - running out
of water and melting the engine is considered poor form, or so I've
heard.
