A turbocharger mainly consists of two main sections: the turbine and the compressor.
The turbine consists of a turbine wheel and the turbine housing whose purpose is to guide the exhaust gases into the turbine wheel.
The kinetic energy of the exhaust gases gets converted into the mechanical after striking it on turbine blades.
The exhaust outlet helps the exhaust gases to get exit from the turbine. The compressor wheel in the turbocharger is attached to a turbine with the help of steel shaft and as the turbine turns the compressor wheel, it draws the high-velocity, low-pressure air stream and converts it into high-pressure, low –velocity air stream.
This compressed air is pushed into the engine with the more quantity of fuel and hence produce more power.

The waste exhaust gases of the engine are utilized to drive a turbine wheel, which is connected to a compressor wheel by a shaft.
Compressor or air wheel sucks in air through the air filters and passes this into the engine.
As the waste gases are expelled from the engine, they are directed to the turbine or hot wheel of the turbo and so completes the cycle.
Instead of escaping through the exhaust pipe, hot gases produced during combustion flow to the turbocharger.
Cylinders inside an internal combustion engine fire in sequence (not all at once), so exhaust exits the combustion chamber in irregular pulses.
Conventional single-scroll turbochargers route those irregular pulses of exhaust into the turbine in a way that causes them to collide and interfere with one another, reducing the strength of the flow.
In contrast, a twin-scroll turbocharger gathers exhaust from pairs of cylinders in an alternating sequence.

The exhaust strikes the turbine blades, spinning them at up to 150,000 rpm. The alternating pulses of exhaust help eliminate turbo lag.
Having served their purpose, exhaust gases flow through an outlet to the catalytic converter, where they are scrubbed of carbon monoxide, nitrous oxides, and other pollutants before exiting through the tailpipe.
Meanwhile, the turbine powers an air compressor, which gathers cold, clean air from a vent and compresses it to 30 percent above atmospheric pressure, or nearly 19 pounds per square inch. Dense, oxygen-rich air flows to the combustion chamber.
The additional oxygen makes it possible for the engine to burn gasoline more completely, generating more performance from a smaller engine.
As a result, the Twin Power engine generates 30 percent more power than a non-turbocharged one of the same sizes.
