What is the principle of a supercharger?

[MacHolden]

Mechanical supercharging works by driving air flow through the meshing of high-clearance gears or rotors. Here is a detailed introduction to superchargers: 1. Function of superchargers: After being compressed by the supercharger, the intake air temperature of the engine will rise significantly. 2. Power source of superchargers: The power for mechanical supercharging comes directly from the rotation of the crankshaft. 3. Three types of superchargers: (1) Centrifugal supercharger: This type of supercharger is similar to a turbocharger, except that it is not driven by engine exhaust but by the engine's belt. It shares the same principle as turbocharging, where air is pressurized by centrifugal force to achieve compression. (2) Roots-type supercharger: Air is drawn into the supercharger and compressed by two spiral-shaped rotors before being sent to the intake manifold. This type of supercharger can provide strong torque output. (3) Screw-type supercharger: When air is drawn into the supercharger, it is forced into the intake manifold by spiral-shaped rotors.
