Funny DIY Mini Air Stirling Engine Motor Model Educational Steam Power Toy Electricity Learning Model Toys for Children Adult

Stirling engines are unique heat engines because of their theoretical efficiency is almost equal to the theoretical maximum efficiency,Called the Carnot cycle efficiency.The Stirling engine is heated by gas expansion,cold contraction generate power. 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 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 and low operating costs.The biggest advantage of the external combustion engine output and efficiency from the influence of altitude,very suitable for high altitude areas. Aerodynamics are rich in knowledge of physics,single cylinder combustion engine.Engine principle is intuitive,educational toys,teaching experimental equipment can effectively cultivate children's interest in learning can also be used for classroom teaching,more intuitive and easy to understand. 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 and dust,and if so,please use toilet paper to erase Not smooth.Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon,the cylinder is sealed.
