What is the stirling engine? A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other , the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.The engine is like a steam engine in that all of the engine's heat flows in and out through the engine wall. How it works? This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and eous phases as the working fluid,the Stirling engine encloses a fixed quantity of permanently eous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool , heating the , expanding the hot , and finally cooling the before repeating the cycle. You can put the stirling motor toy in top of hot water to make the temperature difference. You also can put it in top of ICE to get the termperature difference, Just enjoy the toy!
