Turbocharger serves to increase engine output. This is especially true if the car has a certain displacement. This happens because the air is supplied into the cylinder, which is pre-compressed in the compressor. When more air is fed into the cylinder, respectively, the more fuel is supplied. When it burns, it releases more energy. Thus, the main function of the turbocharger is air injection into the engine cylinders under pressure. Turbocharger construction is not complex. Centrifugal compressor, gas turbine and wheels are rigidly attached to the common shaft.

Exhaust gases enter the chamber of the gas turbine through the outlet pipe. After they are directed to the turbine wheel blades and rotate them together with the shaft. Gazes get into the atmosphere through the exhaust pipe. As for the wheel which is fixed to the shaft, it sucks air from the atmosphere through an air cleaner. Air is pumped into the engine cylinders under excessive pressure on the inlet pipe that increases their filling.
