The relationship between temperature and entropy, and its T-S diagram are presented for a displacer-type Stirling engine operating on a closed reversible cycle. A practical engine has spaces of high and low temperatures, so the temperature and entropy of the working gas are not uniform throughout the engine. In this study the relationship between pressure and volume of working space is obtained using the Schmidt cycle model. Next, the mean temperature of working gas is obtained by integrating the temperatures of high and low temperature spaces. The mean entropy is calculated in the same method as for the mean temperature estimation, using the pressure obtained from the Schmidt cycle model. The validity of the method is confirmed by the agreement of the works on P-V and T-S diagrams. The heat storage in the regenerator is then correlated with the thermal efficiency.
