Types of Supercharge

               Types of supercharge

• Roots Superchargers.
• Twin-Screw Superchargers.
• Centrifugal Supercharger.
• Electric Superchargers. 

1]Roots Supercharge

The roots supercharger traps air in a chamber between the rotor and the housing, in the void between the rotor's lobes, and transports this trapped air to the outlet side, at the engine's intake manifold. By virtue of moving air into the manifold at a rate higher than the engine consumes it, pressure is built..

*Advantage*

1)The Roots-type supercharger adds a lot of power to the vehicle.

2) The power delivery is instantaneous, the throttle response is smooth, and the torque curve is equally improved across all RPM.

*Disadvantage*

1) In the range of partial load, the conveying speed is higher, i.E. Wear on the conveyor pipe and breakage of the conveying material will be greater.

2) A conveying speed once chosen can only be altered with considerable expenditure.

2]Twin-Screw Superchargers.

In a twin-screw style supercharger, the two rotors are designed to mesh with one another and compress the air forced between them. So while they're both similar in design, twin-screw superchargers compress the air directly while roots superchargers create pressure in the manifold that compresses the air.

*Advantages*

1) More horsepower and boost can be            achieved as compared to root type             supercharger.

2) During the each rotation, a specific             fixed amount of air is trapped and moved to discharge side where it is compressed

3) Less noisy.

*Disadvantage*

1) Installation is complex

2) Continuously compression and                    discharge irrespective of boost                    requirement at low or high speed.

3) It also exhibits heating issues but less        as compared with the root type.

3]Centrifugal Supercharger. 

A centrifugal supercharger is a specialized type of supercharger that makes use of centrifugal force in order to increase the manifold air pressure, MAP. An increased MAP allows the engine to burn more fuel, which results in an increased power output. Centrifugal superchargers are generally attached to the front of the engine via a belt-drive or gear-drive from the engine's crankshaft.

*Advantage*

1) Boost level is high compared to other superchargers . 

2) Parasitic load: power required to turn centrifugal supercharger is very less

3) Less heat generation.

*Disadvantage*

1) More Engine oil required.

2) Not great for low rpm boost.

3) Its performance is directly related to          engine speed. 

4]Electric Superchargers. 

An electric supercharger is a specific type of supercharger for internal combustion engines that uses an electrically powered forced-air system that contains an electric motor to pressurize the intake air. By pressurizing the air available to the engine intake system, the air becomes more dense, and is matched with more fuel, producing the increased horsepower to the wheels.

*Advantage*

1) compress air and increase the amount        of air delivered to an engine. 

2) electric motor can not only be used to         drive the turbocharger shaft, but it can         also be used to brake it. 

*Disadvantage*

1) electric turbocharging will remain comparatively expensive for some time.
