Your car's turbo or turbocharger is a device that increases your engine's power by pumping air into the combustion chamber. Having a turbo in your car makes the vehicle more powerful and efficient. Your turbocharger is driven by the engine's exhaust gas turbine. It functions with the help of components like the inlet and compressor wheel, oil inlet, turbine wheel and housing, blow-off valves and wastegates.
The air is forced into the inlet and rotated by the compressor wheel, making it highly dense. The hot air then enters the turbine inlet. The hot air spins the turbine wheel creating back pressure and causes a higher pressure on the exhaust. The wastegate, a bypass valve for the exhaust to flow from the turbine wheel, controls the boost pressure of the engine. The oil inlet of the turbo helps in running the device smoothly. The blow-off valve prevents the compressor from thrust bearing failure.
