A Stirling engine is a heat engine that operates by cyclic compressionand expansion of air or other gas， the working fluid， at differenttemperature levels such that there is a net conversion of heat energy tomechanical work.The engine is like a steam engine in that all of theengine's heat flows in and out through the engine wall. How it works? This is traditionally known as an external combustion engine in contrastto an internal combustion engine where the heat input is by combustionof a fuel within the body of the working fluid. Unlike the steam engine'suse of water in both its liquid and gaseous phases as the working fluid，the Stirling engine encloses a fixed quantity of permanently gaseousfluid such as air or helium. As in all heat engines， the general cycleconsists of compressing cool gas， heating the gas， expanding the hotgas， and finally cooling the gas before repeating the cycle.
