What is the principle of a supercharger?

[VanWyatt]

Mechanical supercharger works by: the engine crankshaft drives the supercharger body through a chain or belt to force air in, the compressed air is cooled and then enters the engine's combustion chamber to mix with fuel, and is compressed for ignition to perform work. A mechanical supercharger, also known as a supercharger, is a forced induction device for internal combustion engines. The mechanical supercharger utilizes the torque generated by the engine crankshaft, with a design purpose largely similar to that of a turbocharger, both aiming to draw more air into the engine through an air compressor, supplemented by an increased fuel supply, to enhance the engine's output power.
