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.
 Features:1. This engine is exquisite in appearance, small and exquisite.2. Piston and cold cylinder are made of metal, strong and durable; The heating head is a quartz tube, and will not break under instantaneous high temperature or cooling. 3. Just a little alcohol can make it quickly run up, whether as an experimental teaching material or give it away is the best choice.4. The design structure is exquisite, easy to dismantle, can cultivate children's hands-on ability. Package Included: 1 x Mini Vertical Stirling Engine Model
