This is an external combustion engine in which the fuel is burned continuously, and the piston is moved by the expansion of air or helium or hydrogen as a medium, and the expansion gas is cooled in the cold chamber, and the cycle is repeated. Only a small alcohol lamp, you can make it fast rotation and generate strong power.
As the external combustion engine, it avoid the explosion risk when traditional internal combustion engine working, in order to achieve a high efficiency, low noise, low pollution and low operating costs.
The biggest advantage of the external combustion engine is that the output and efficiency are not influenced by altitude, very suitable for high altitude areas.
Instructions:
Put the engine model on the horizontal position, toggle the flywheel to see if it is smooth, if there is a strong sense of raw astringent, check the connection rod, whether the cylinder has oil and dust, and if so, please use toilet paper to erase. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.
The packing bag of alcohol lamp cotton wear into the metal cap lamp.
