What is Supercharger?
It is used for pressurizes the air at intake or increase the air density which supplied to internal combustion, more air means more oxygen allowing it to burn more fuel and to get more power by increase in air during the combustion of an engine. Here we will learn about different types of supercharger.

Types of Supercharger
1. Roots Type Supercharger:
- Excellent reliability.
- Low rpm big boost; at low engine speed it can produce greater boost.
- Simple in design.
- Creates lots of heat.
- Heavy in weight and due to bigger in size it can comes out of the hood.
- Least efficient.
2. Twin-Screw Supercharger:
- It provides Instant boost.
- Noisy, it means it more noise during its working.

3. Centrifugal Supercharger:
- High thermal efficiency and creates less heat.
- Small and compact in size.
- Bad low rpm boost; there is no fixed amount per revolution.
After Supercharging Process:
As the air is compressed at the end of supercharger, air gets hotter, this means that it loses its density so air molecules are less and cannot expand as much during the explosion in combustion chamber. For a supercharger to work at efficiency, the compressed air needs to cool down for more air molecules. At the discharge unit compressed air must be cooled before it enters the intake manifold. The intercooler is responsible for this cooling process. Due to intercooler reduction in air temperature, the density of the air increases, which makes more oxygen entering the combustion chamber.In this article we have learnt about types of supercharger used in automobile for boost of engine. if you find anything missing or incorrect then comment us.
