Feature

●The Sterling Engine is a heat engine that converts thermal energy into a mechanical function by repeatedly compressing and expanding of gases such as temperature difference air
●The addition of lubricating oil is prohibited because it mixes with dust in the air, and eventually increases friction and prevents rotation of the air
●This engine just like a steam engine, all the heat of the engine goes in and out through the engine wall
●Suitable for students engine principle puzzle toys, educational experimental equipment, can cultivate students who love physics, learn alive, train brain and hand ability

Note:
Use the pencil to smooth it
If necessary, only use pencil powder to lubricate this sterling engine.
Do not add oil to lubricant. The oil will be mixed with dust in the air and grease, so the friction needs to be larger. Sterling engines cant move freely.
