What are the advantages of an air-cooled engine?

[KateLee]

Air-cooled engines have the following advantages: simple structure, lightweight, easy maintenance and use, strong adaptability to climate changes, quick start-up, and no need for a radiator. An air-cooled engine is a type of engine that uses air as the cooling medium. It has cooling fins cast on the outer walls of the cylinder and cylinder head, and a cooling fan blows air at high speed over the surface of the fins to carry away the heat dissipated by the engine, thereby cooling it. Air-cooled engines are widely used in motorcycles, eliminating the need for a radiator. They are also used in water-scarce areas because they do not require water as a cooling medium. Their disadvantages include: poor rigidity of the cylinder block and cylinder head, high vibration and noise levels, and a tendency to overheat.
