Problems solved by technology

[0002] The air-cooled piston engine is widely used in aviation, navigation, vehicles, general machinery and other industries due to its advantages of simple structure, light weight, convenient maintenance, and low manufacturing cost. However, the low cooling efficiency and difficult temperature control seriously affect the engine. The output of power and torque, the unstable working temperature also increases fuel consumption, serious emission pollution, increased wear and shortened service life due to temperature changes, which seriously restricts its application, so air-cooled piston engines are mostly used in places with small power and low cost. Being buried and not getting a lot of applications
[0003] Regarding the fuel consumption and emissions under the same power, a large part of the piston engine’s own loss comes from the friction between the cylinder, piston, and piston ring. When the temperature is too low, this friction will increase due to metal cold shrinkage. The denaturation of lubricating oil leads to insufficient lubrication, which leads to increased friction and wear, that is to say, the fuel consumption will increase if the temperature is too high or too low; too high temperature will cause the mixture to burn too fast and cause knocking, and knocking will not only damage the engine but also make the engine Combustion produces abnormal toxic substances; the engine temperature is too low and the combustion speed of the mixture slows down, and the incomplete combustion increases pollutant emissions
