What Does a Supercharger Do?


Quick Answer

A supercharger pressurizes the air supplied to an internal combustion engine, generating more power for the vehicle. This extra power arises because more air is pumped into the combustion chamber of the engine in a single intake cycle, allowing more fuel to be burnt.

Full Answer

The supercharger is typically powered mechanically by a belt or a chain coupled to the crankshaft of the engine. This causes the air intake of the engine to compress. A side effect of the air compression is that the temperature of the air simultaneously increases. This could result in undesirable spontaneous combustion before the spark ignition. This pre-ignition can be prevented with inter-cooling.
