Shirai, et al (2016) theoretically investigated on the universal trade-off relation between the power, P, and the thermal efficiency, η, for heat engines. They indicated that P became 0 at both η = 0 and ηC (Carnot efficiency) and became the maximum at (1/2)ηC. The present study explored this subject though a model on piston-cylinder thermal cycle system with finite period, τ. State change of the gas was characterized by the Tv-diagram. The present model brought qualitatively the same trade-off relation by Shirai et al. (2016).
