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. as the working fluid, the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cyclePackage include:1*Twin Flywheels Hot Air Stirling Engine (not included alcohol)
