The Stirling engine was invented by Robert Stirling, a Scottish minister, in 1816, and the principle of this engine is based on the Stirling cycle which is consisted of two isothermal changes and two constant volume changes. At that time, thermal efficiency of this engine was considerablly low because of the use of air as the working fluid and of the low efficiency of regenerator. But in last decade, this engine was developed to highly efficient prime mover, for high pressure hydrogen or helium gas was used as the working fluid and the efficiency of the regenerator was improved. As the result, thermal efficiency of this engine has increased as high as that of the internal combustion engine. Because the Stirling engine has an external combustion system, low level of vibration, noise and emission characteristics of this engine are suitable for marine, automobile and other use. In this paper, recent development on Stirling engine is reviewed with the theoretical and experimental analysis which was reported in last decade in many countries, and described on the capability of the application in many fields. It is seemed that the points of problem of this engine is laid on sealings, heat transfer units and controls.
