Which type of compressor is typically used in a supercharger?

In the context of supercharging, centrifugal compressors are widely utilized due to their ability to efficiently increase the pressure of the intake air. The design of a centrifugal compressor allows for a high air flow rate and a significant pressure rise in a compact system, making it suitable for high-performance applications such as in superchargers. These compressors work by converting rotational energy from a turbine or other power source into kinetic energy, which is then transformed into pressure energy.

The response time of centrifugal compressors is generally quick, allowing them to adapt to varying engine loads and speeds. This characteristic makes them particularly advantageous in automotive applications where performance is essential, as they can provide the requisite boost in air flow to support enhanced engine performance and efficiency.

While axial compressors and other types have their own applications in different engines and systems, the centrifugal design is specifically favored in supercharging for its effective pressure generation and efficiency at various operating conditions.
