Stirling Engine Model Vacuum Motor Model Kit Description Engine Model Vacuum Motor Model KitFeatures With the help of the flywheels then a net conversion of heat energy to mechanical work Mechanical work through small generators produce electricity to power a light bulb Can be used for teaching purpose 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 engines 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 engines 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 Specification Item Name Vacuum Power Generation EngineModel QX ZK 01Material WoodMetalDimension 150 70 90mmWeight 280g Package Included 1 x Vacuum Motor Model Kit not included alcohol
