Turbocharger: Description and Operation
Turbocharger Operation
Cut-Away View Of Turbocharger
The turbocharger is comprised of 2 impellers (compressor and turbine) connected by a single shaft, bearings, seals, and the housing that contains these
components. The turbine impeller is driven by, and located in the exhaust stream. The compressor impeller is driven by the turbine impeller and located
in the intake air stream. The compressor impeller compresses the intake air before it enters the intake manifold.
When the compressor impeller rotates, it creates and forces a highly compressed amount of air into the combustion chamber. As more air (and fuel) is
forced into the combustion chamber, more horsepower is developed due to higher density and compression of the incoming air. The amount of air that
enters the combustion chamber is dependant upon the rpm of the turbocharger. As the rpm of the turbocharger increases so does the amount of air that is
