Whoohoo! Thanks!

Sui. That's a kind of chef, right?

Why is the word 'science' in the title graphic?

Under the description header in that wikipedia link "A process that does NOT involve the transfer of heat or matter into or out of a system, so that Q = 0, is called an adiabatic process, and such a system is said to be adiabatically isolated.[4][5] The assumption that a process is adiabatic is a frequently made simplifying assumption. For example, the compression of a gas within a cylinder of an engine is assumed to occur so rapidly that on the time scale of the compression process, little of the system's energy can be transferred out as heat to the surroundings. Even though the cylinders are not insulated and are quite conductive, that process is idealized to be adiabatic. The same can be said to be true for the expansion process of such a system." So essentially under high shaft velocities the heating has little/no/less time to occur whereas lower velocities experience heating....and presumably a higher rate of pressure gain through the stroke. So basically the opposite of the heating process occuring at higher speeds.
