WHAT IS SUPERCHARGER?
A supercharger is an air compressor used for forced induction of an internal combustion engine.
The greater mass flow-rate provides more oxygen to support combustion than would be available in a naturally aspirated engine, which allows more fuel to be burned and more work to be done per cycle, increasing the power output of the engine.

OPERATION OF SUPERCHARGER

Roots Type The Roots type
supercharger or Roots blower is a positive displacement lobe pump which operates by pumping fluids with a pair of meshing lobes not unlike a set of stretched gears. Fluid is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust

Centrifugal Type The centrifugal-type
supercharger is an engine-driven compressor used to increase the power output of an internal-combustion engine by increasing the amount of available oxygen by compressing air that is entering the engine. This type of supercharger is practically identical in operation to a turbocharger, with the exception that instead of exhaust gases driving the compressor via a turbine, the compressor is driven from the crankshaft by a belt, gear or chain drive.

Screw Type Lysholm is also called screw
type supercharger. The supercharger consists of
2 screws, one with male threads and another with female threads. They closely mesh together. When they rotate, air is captured between the screws and the housing while being pushed from the inlet towards the outlet. Moreover, the space gets smaller and smaller as it moves forward, so Lysholm performs internal compression and enables higher boost pressure than Roots type supercharger.

ADVANTAGES AND DISADVANTAGES OF SUPERCHARGED
![Page 19: Supercharger](https://reader033.vdocument.in/reader033/viewer/2022061221/54bd041d4a7959f6768b45c0/html5/thumbnails/19.jpg)
ADVANTAGES OF SUPERCHARGER
Advantages of a Supercharger 1). Increased power 2). No lag – Consistent power delivery 3).Generally better throttle response 4). No Special Procedures or extra
maintenance 5). Centrifugal Superchargers are more
efficient at higher RPM 6). Roots & Twin Screw Superchargers are
efficient at low RPM 7). Easier to tune 8). Easier to install than turbochargers

DISADVANTAGES OF SUPERCHARGER
1). Consumes a lot of power from the engine (therefore not very efficient)
2). Increases the strain on the engine 3). Increases the strain on the running gear 4). Expensive 5).Noise
