| Abstract: | Under the circumstances of two given temperatures of heat sources and compression ratio, the optimal performance of engines with finite process rate due to the existence of inertial effect and heat resistance is discussed. The relation between the optimal efficiency and power output of the engines for an ideal or van der Waals gas as a working fluid is derived. Some new conclusions concorning the compression ratio are deduced. |
