Turbocharger vs Supercharger | Differences Between Turbocharger and Supercharger.

Turbocharger vs Supercharger. The power generated in the IC engine is directly related to the compression force exerted on the air-fuel mixture. In the other words, the greater the compression, the greater the output of the engine. In previous articles, I discussed turbochargers and superchargers. Today in this article, I will discuss the differences between these two force induction power systems. 

Turbocharger vs Supercharger-

The main difference between Turbocharger and Supercharger is that the Turbocharger is driven by the exhaust gas of an engine, whereas The supercharger is directly driven by the engine through a belt drive. In order to understand the Difference Between Turbocharger and Supercharger it is essential to first know what is a Turbocharger and a Supercharger. First, take a look at what is the turbocharger and supercharger- 

Turbocharger- 

It is a turbine-driven forced induction device that increases an internal combustion engine’s efficiency and also power output by forcing extra compressed air into the combustion chamber. The turbocharger is used in trains, cars, buses, and other engines.

Supercharger- 

The supercharger is also called an air compressor. The function of an air compressor is to compress the fuel which means increasing the pressure of the fuel of an ic engine. Increasing the pressure of fuel means the burning of fuel will be more and fast, which will provide more work.

Differences- 

The main differences between Turbocharger and Supercharger are Turbocharger is not connected directly to the engine and whereas a Supercharger is a direct connection with the engine through the belt. Here are some differences-

SL. No	Turbocharger	Supercharger
01	The turbocharger is not connected directly to the engine.	The supercharger is a direct connection with the engine through a belt.
02	It has smog-altering equipment that lowers carbon emissions.	The supercharger does not have a wastegate. So the smog emits from a supercharger.
03	It uses exhaust gas for its energy.	It is a connected crankshaft of the engine for its energy.
04	The spinning rate is 15000 RPM	The spinning rate is 50000 RPM.
05	This is a device consisting of both the turbine and compressor mounted on the same shaft.	This is basically a compressor.
06	It does not need any extra power.	Here in the supercharger extra power is to be supplied.
07	It drew power from exhaust gases.	It drew power from the engine.
08	It takes time to spin up to the speed hence there is lag.	Here no lag. Power delivers immediately.
09	Higher speed achieved.	Greater acceleration is achieved.
10	Difficult maintenance.	Easy maintenance.
11	This is costly.	This is cheap.
12	More efficient because it drew power from exhaust gases.	A supercharger is less efficient.
13	Suitable for an engine with higher displacement.	Suitable for an engine with lower displacement.
14	Turbos won’t start operating until a sufficient amount of exhaust gases is produced.	Superchargers start working as soon as the engine starts.
15	Here a compressor is rotated by the turbine.	The compressor is rotated by the engine crankshaft through a belt.
16	This is more complex.	but this one is less complex.
17	The intercooler requires here to for lowering the temperature of compressed air.	The chances of the requirement of the intercooler are negligible. But some time is needed.
18	The compressed air has a high temperature in the turbocharger.	The compressed air has a low temperature in the supercharger.
19	This is less reliable.	This is more reliable.
