A turbocharger consists of a single turbine the rotor of which is mounted on the same as with the impeller of a compressor. The turbocharger uses some of the energy of the hot gases of the engine to drive the turbine. The turbine, being on the same shaft with the impeller of the compressor, the power to the impeller and drives the compressor. The compressor compresses the air which then is cooled and enters the air manifold. Besides the rotor, the turbine assembly has a stator too, that is, stationary vanes which direct the exhaust gases to the rotor. On the compressor’s side on the other hand, there is a and a spiral casing, both of which contribute to further rising of the pressure of the compressed air. There is also a to absorb the noise of the vibration of the running .
