Supercharger
A supercharger is a compressor driven by the engine that forces more air into the cylinders for more power.
What is Supercharger?
Types include Roots, twin-screw and centrifugal superchargers. Some engines use electric compressors. Unlike a turbocharger, it responds instantly but uses some engine power to drive it. Some superchargers have an electromagnetic clutch or bypass valve so they only work when extra power is needed.
How it works
A belt or gear from the crankshaft spins the compressor, which pushes air into the intake under pressure.
Why it matters for your car
Whining is normal for some types, but new noises or loss of boost need checking. Superchargers usually have their own oil or are lubricated by engine oil; follow the service schedule for them.
