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.
As the external combustion engine to avoid the traditional internal combustion engine of the explosion to do work, in order to achieve a high efficiency, low noise, low pollution and low operating costs.The biggest advantage of the external combustion engine output and efficiency from the influence of altitude, very suitable for high altitude areas.
Aerodynamics are rich in knowledge of physics, Engine principle is intuitive, educational toys, teaching experimental equipment can effectively cultivate children’s interest in learning can also be used for classroom teaching, more intuitive and easy to understand.A floating bead links 8 cylinders and its piston to drive based on the motor power from hot air, hard to believe it is a engine model, super cool,8 cylinders, 8 heating tube.8 fire-outlet sparks the fire flame to the stainless heating tube, cool.
