What is the 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.
 
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 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.
 
Instructions:
- The engine model on the horizontal position by hand toggle the flywheel to see if smooth, if there is a strong sense of raw astringent, check the connection rod is normal, whether the cylinder oil and dust, and if so, please use toilet paper to erase Not smooth. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.
- Please go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better. Fill the alcohol lamp to less than two-thirds.
- Alcohol lamp to the alcohol lamp, at the premise of ensuring safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel automatic operation so far, the whole process of heating, hands may not touch.
 
Warning:
- Please adopt 95% to highgrade alcohol to be the fuel to make sure the air tank can get more temperature, and drive the stirling engine. Please do not full fill the alcohol.
- After the alcohol lamp burn for about 2 minutes, please stir the Flywheel.
- Do not rotate the piston too tightly, otherwise the glass will broken, if the piston is cracked, can be bonded with glue.
- The lamp core of the alcohol lamp cannot touch the heating cylinder.
- The connecting rod and crankshaft should not be too tightly, otherwise it will not work.
- Prohibit to add any oil or water to the heating cylinder or the power cylinder.Because the oil or water will mix with dust in the air, and become a oil-dirt, finally make the friction to be even bigger. The stirling engine can't run freely.
- Because this machine after ignition moving like a car, please be careful. Don't play in the places where inflammable.
- Children accompanied by adults and parents to play. Please do not touch the cylinder after burned.
