How the engine works? This type of engine 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 fluid, the 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. General Information: SUPER COOL -- a in-built RGB LED (mixture color LED) designed on the micro motor, when the engine is running, it will emit a colorful light, looks super cool! COMPACT DESIGN – it is a very compact design, good for physics / mechanical education demonstration how the heat energy convert to mechanical energy, the heating glass tube in glass basis show a clear picture how the piston works EASY TO RUN -- It is a assembled engine (for shipping safety purpose, the glass heating tube is not installed on); It is ready to run, super free running, what you need to do is just to prepare the fuel to run (the fuel we recommend to use 95% alcohol or other fuel that is equivalent to 95% alcohol heat-energy) General Information: Revolution : 1500rpm (maximum) Flywheel Diameter : 54 mm Drive wheel diameter : 24 mm Power Cylinder Inner Diameter : 14.0 mm Piston Stroke : 16.0 mm Cylinder Inner Diameter : 19.0 mm Unit Dimension : 205(L) x 100(W) x 90(H) mm Engine Weight : 480g Base : Bare Bamboo Package Contents: 1 x Engine Unit 1 x Fuel Burner
