Size: 155*130*80 mm Weight: 628g Flywheel Diameter: 60mm Transmission Wheel Diameter: 25mm Power Cylinder Bore: 12.5mm Piston Stroke:13mm Generating Voltage: 3-5v Suitable Age: 8 years old & above Experiment Type: physical Package: Small Carton Metal Base style: Mirror Features-This is an external combustion engine in which the fuel is burned continuously, & the piston is moved by the expansion of air (or helium or hydr ogen) as a medium, & the expansion gas is cooled in the cold chamber, & the cycle is repeated. Only a small alcohol lamp, you can make it fast rotation & 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 & low operating costs.-The biggest advantage of the external combustion engine output & efficiency from the influence of altitude, very suitable for high altitude areas. Instructions-The engine model on the horizontal position by hand toggle the flywheel to see if smooth, if there is a strong sense of raw astringent, check the connection rod is normal, whether the cylinder oil & dust, & if so, please use toilet paper to erase Not smooth.
