A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing power. Power for the supercharger can be provided mechanically by means of a belt, gear, shaft, or chain connected to the engine’s crankshaft. When power is provided by a turbine powered by exhaust gas, a supercharger is known as a turbosupercharger – typically referred to simply as a turbocharger or just turbo.

Supercharging increases power, but turbocharging can improve power and efficiency. Turbochargers were known as turbosuperchargers when all forced induction devices were classified as superchargers. Currently, the term supercharger is only applied to mechanically driven forced induction devices.
