A turbocharger, or turbo (colloquialism), from Greek `τύρβη` (`wake`), (also from Latin `turbo` (`spinning top`),) is a turbine-driven forced induction device that increases an engine`s efficiency and power by forcing extra air into the combustion chamber. This improvement over a naturally aspirated engine`s output results because t...

(Turbo) An air compressor or SUPERCHARGER on an internal combustion piston engine that is driven by the engine exhaust gas to increase or boost the amount of fuel that can be burned in the cylinder, thereby increasing engine power and performance. On an aircraft piston engine, the turbocharger allows the engine to retain its sea-level power rating ...

Device that compresses and forces extra air into the intake manifold to produce extra power. Both turbochargers and superchargers are used to produce more power without increasing engine displacement, but neither are particularly fuel efficient and both can require costly maintenance as vehicles age. By forcing fuel through the engine, this system ...

Attached to the engine, a turbocharger uses an exhaust driven turbine to drive a compressor to increase the density of the intake air consumed by the engine. Denser air helps an engine create more power for its size. The residual heat energy contained in the exhaust gases after expansion in the cylinders of the engine is converted to mechanical sha...
