Conclusion.
Supercharger, The Engine Booster
A supercharger is an equipment that compresses the air being delivered to an engine, allowing the combustion chamber to be overfilled without enlarging
the space.
The higher concentration of
oxygen provided by a super-
charger is matched with a larger
amount of fuel from the fuel injectors
thus boosting the power of the
engine.
Why Supercharger ??
Increases the power of an engine.
A supercharger spinning at 50,000 RPM translates to a boost of about six to nine pounds per square inch(psi).
Increases the torque produced.
An efficiently working supercharger can achieve the same speed in one third time.
Necessary in aero-planes as they have less oxygen at high altitudes.
Ensures complete combustion of the fuel.
Reduces pollution to some extent.
