                  What's Stirling 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 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 gaseous phases 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 cycle.

                  How To Use?
                  1. Inject fuel into each alcohol wick with a needle type plus alcohol.
                  2 Full filled the fuel tank.
                  3.Light the alcohol wick and heat it for 30-50 seconds. Clockwise dial the gyro flywheel to start the model operation.(The alcohol wick can not touch the glass hot cylinder )
                  4.Medical alcohol with 95% fuel concentration works best.
                  5.Debugging instructions:
                  If the operation is not good, you can adjust the length of the following two wick, increase the firepower.(The height of both wick can be adjusted)

                  Recommmended age: 14+. Adults' guidance is required for young children.
                  Please add alcohol fuel slowly.
                  Be careful of the fire and keep away from the flammable objects when using the engine.
