How Turbochargers Work
Principle of operation
A turbocharger is a dynamic gas compressor or liquid pump, in which a fluid from one stream is pumped, and in he case of a gas compressed, by the mechanical action of an impeller which is powered by a turbine that recovers energy from another fluid stream.
In almost all cases the impeller and turbine are mounted on ends of a single shaft passing through a center hub rotating assembly (CHRA) between the impeller and turbine. The CHRA contains bearings for the shaft and may also contain systems for lubrication and cooling.
