How Turbocharger Works?

A turbocharger is a type of forced induction system that increases the amount of air entering the engine, allowing it to burn more fuel and produce more power. It consists of a turbine and a compressor that are connected by a shaft.

The turbine, located on the exhaust side of the engine, is powered by the exhaust gases. As the turbine spins, it drives the compressor, which is located on the intake side of the engine. The compressor compresses the incoming air, increasing its density and allowing more oxygen to enter the combustion chamber.

This results in a more powerful combustion, which in turn increases the engine’s power output. Additionally, turbochargers also help to improve the engine’s fuel efficiency by using the exhaust gases to compress the intake air, instead of consuming extra power from the engine.
