Supercharging refers to the use of mechanical devices to increase the air pressure in the engine exhaust system, thus improving the output power and efficiency of the engine. There are several forms of supercharging. Let's introduce them in detail.

First of all, the most common form of supercharging is turbocharger. Turbocharger is a mechanical device that can use exhaust heat to improve the output power and efficiency of the engine. It is realized by a turbine and a compressor. The turbine extracts exhaust heat from the exhaust pipe, and the compressor compresses the exhaust air, thus improving the output power and efficiency of the engine.

Secondly, there is a mechanical supercharger called "super supercharger". Supercharger is a mechanical device that can use exhaust heat and exhaust pressure to improve the output power and efficiency of the engine. It is realized by a super supercharger and a compressor. The super supercharger extracts exhaust heat energy and exhaust pressure from the exhaust pipe, and the compressor compresses the exhaust air, thus improving the output power and efficiency of the engine.

Finally, there is a mechanical supercharger called "mechanical turbocharging". Mechanical turbocharging is a mechanical device that can use mechanical energy to improve the output power and efficiency of the engine.
