Educational model of combustion of external Stirling engine with colored LED diodes Description: Physical DIY Kits — Stirling Engine Model Combustion Engine with LED Lights Made of galvanized aluminum, resistant to high temperature and resistance to low temperatures -As with the internal combustion engine (EC engine): the burning lampa provides heat output to expand the gas inside, then the internal gas power increases and acts strongly on the flywheel. Za the help of flywheels, thermal energy will be converted into mechanical work and then into electrical energy LED colour LEDs directly demonstrate the process of converting thermal energy into electricity Great educational toy-class or experimental teaching aids, nurture children's interest in physics, more intuitive and easy to understand An engine is a heat engine that operates by cyclically compressing and expanding air or other gas (working fluid) at different temperatures so that there is a conversion of netto of heat energy into mechanical work. Specification: Material: metal and glass Color: Temperature range:-30 ℃ - 700 ℃ Size when folded (L. x W ): approx. 18x9x14 cm / 7,09x3,54x5,51 inch The package includes: 1 set Engine model with colored LED diodes
