What Is a Turbocharger?

A turbocharger is a high-precision device that increases an engine’s power by forcing more air into the combustion chamber.
More air → better combustion → more power without increasing engine size.

It uses exhaust gases—energy that normally gets wasted—to create extra boost for the engine.

How a Turbocharger Works: Simple Explanation

A turbocharger has two main parts:

Turbine (Exhaust Side)

Exhaust gases from the engine spin the turbine wheel at extremely high speeds (up to 200,000+ RPM).

This side uses waste exhaust energy.

Compressor (Air Intake Side)

The turbine is connected to a compressor wheel with a shaft.

When the turbine spins, it also spins the compressor.

The compressor pulls in fresh air and compresses it before sending it into the engine.

Step-by-Step Working Process
1. Exhaust Gas Enters the Turbo

Hot exhaust gases flow out of the engine and enter the turbine housing.

2. Turbine Wheel Spins

The force of the exhaust spins the turbine wheel at extremely high speed.

3. Compressor Wheel Pressurizes Air

The turbine is connected to the compressor wheel by a shaft.
As the turbine spins, the compressor wheel also spins and sucks in outside air.

4. Compressed Air Goes Into the Engine

The compressed air is pushed into the engine’s cylinders.
More air → more oxygen → stronger combustion.

5. Engine Produces More Power

The engine burns more fuel efficiently, giving:

More power

Better mileage

Lower emissions

Why Turbochargers Are So Effective

They use wasted exhaust energy to improve performance.

They allow small engines to produce the power of big engines.

They improve fuel economy and reduce pollution.
