A turbocharger, or turbo (colloquialism), from the Greek
"τύρβη" (mixing/spinning) is a centrifugal compressor
powered by a high speed turbine that is driven by an
engine's exhaust gases. Its benefit lies with the compressor
increasing the mass of air entering the engine (forced
induction), thereby resulting in greater performance (for
either, or both, power and efficiency). They are popularly
used with internal combustion engines (e.g., four-stroke
engines like Otto cycles and Diesel cycles). Turbochargers
have also been found useful compounding external combustion
engines such as automotive fuel cells.[1]

The term turbocharger is a modern one, derived by shortening
the turbosupercharger, which was widely used during the
World War II era and earlier. This term refers to the fact
that turbochargers are a specific type of supercharger, one
that is driven by a turbine. The most common form of
supercharger at the time, which was often referred to as a
"geared supercharger", was mechanically driven by the
engine, whereas turbochargers are always driven by a turbine
that gets its power from the engine's exhaust stream.[2]
Twinchargers combine a supercharger and turbocharger.
