Introduction A turbocharger (also called turbo), is a turbine-driven forced induction device that increases an internal combustion engine’s efficiency & power output by forcing extra air into the combustion chamber. The key difference between a turbocharger & a conventional supercharger is precisely that a turbocharger is powered by a turbine driven by the engine's exhaust gas. A turbo consists of a compressor, a cartridge, a turbine & an exhaust valve.
