use pencil to lubricate it

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 contrastto 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’suse of water in both its liquid and gaseous phases as the working fluid,the Stirling engine encloses a fixed quantity of permanently gaseousfluid such as air or helium. As in all heat engines, the general cycleconsists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.

This good-looking Low Temperature Stirling Engine could be a great gift for your friends or families or yourself. It is almost ready to run: you will only have to install the flywheel. After 30 seconds of installation, put it on a cup of hot water, then it will run like Forrest Gump.

Note: the various parts of the crankshaft and connecting rod can use pencils to lubrication, never oil lubrication, once produce oil dirties, friction is very big, and not easy to clean up!!!!
