A car turbocharger is a device that boosts the engine’s power by increasing the air pressure in the cylinders. It consists of two main components: a turbine and a compressor. The turbine is driven by the exhaust gas from the engine, and the compressor is connected to the turbine by a shaft. The compressor draws in fresh air, compresses it, and delivers it to the engine intake manifold, where it mixes with the fuel and ignites. By forcing more air into the combustion chamber, the turbocharger allows the engine to burn more fuel and produce more power.
