TURBOCHARGER VS SUPERCHARGER

Ever wondered what is Supercharger or Turbocharger? Most of us may have heard these words in movies or may have seen it in real life. Since both of them are used to increase the efficiency and power of the engine, let's see how they perform. 

 TURBOCHARGER VS SUPERCHARGER

SUPERCHARGER:-

To boost the power of the engine there are two ways: one is to make the size of engine big which of course will weigh more and is not feasible, and another way is to make the engine more efficient which is to supply more air into the combustion chamber.

More air means more fuel which in turn will increase the horsepower of the engine. A Supercharger is basically an air compressor. It compresses the air above the atmospheric pressure and then it is fed t the intake valve of the engine.

The supercharger is driven by the engine crankshaft either with a belt drive or a chain drive. As the crankshaft rotates the pulley attached to the supercharger also rotates which is connected to the rotors in the supercharger. Due to the rotation, the air is sucked in, the rotors then compress this air making it denser. 

Since compressing the air make it hotter, hence an intercooler is mounted in between the supercharger and the intake manifold of the engine. The supercharger adds 46 percent of the increase in horsepower and a 31 percent increase in torque. The first supercharged car was the Mercedes Kompressor Model which made its debut in 1923.

TYPES OF SUPERCHARGER:-

• Root type Supercharger
• Twin Screw Supercharger
• Centrifugal Supercharger

SUPERCHARGED CARS:-

• Chevrolet Camaro 
• Audi A6
• Jaguar F-pace
• Volvo XC90

TURBOCHARGER:-

Turbochargers are similar to the superchargers but the difference is that it is driven by the exhaust gas which is emitted by the engine. Both fall under the category of dynamic compressors. The aim of turbos and superchargers is the same both are used to increase the engine's efficiency.

Turbos are also called free power source devices as they are driven with the help of exhaust gases, unlike superchargers which are driven by the engine using a belt or chain drives.

A turbocharger consists of two halves which are connected with the help of a shaft. One half is fed with the exhaust gases which in turn rotates the shaft, due to which the other half is rotated, a vacuum is created and the air is sucked in. This air is then compressed and fed in the intake manifold of the engine. Sometimes the pressure inside the turbo is so high which has to be revealed to avoid any consequences hence an Air Bypass Valve is provided to relieve the pressure. A turbocharger can boost the engine's hp by 15 to 25 percent.

TYPES OF TURBOCHARGERS:-

• Single Turbo
• Sequential Turbo
• Twin-Scroll Turbo
• VGT (Variable Geometry Turbo)
• Variable twin-scroll Turb
• Electric Turbo

TURBOCHARGED CARS:-

• Tata Nexon
• Mahindra XUV300
• Hyundai Venue
• Hyundai Grand i10 Nios Turbo
• Audi A3

SO WHO'S THE WINNER?

Both are used to increase the engine's power. Surely supercharger increases more power than that of the turbocharger. Since supercharger requires engine power to get in working and turbo works with the help of exhaust gases. Therefore TURBOCHARGER is the winner. Being feasible it has been adopted by many automotive industries.
