Hot Air 8 Cylinder Stirling Model Engine


A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, 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.This is an external combustion engine in which the fuel is burned continuously, and the piston is moved by the expansion of air as a medium, and the expansion gas is cooled in the cold chamber, and the cycle is repeated.

Only a small alcohol lamp, you can make it fast rotation and strong power.Unlike the steam engine’s use of water in both its liquid and gaseous phases as the working fluid, the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium.
