IntroductionA turbocharger (also called turbo), is a turbine-driven forced induction device that increases an internal combustion engine’s efficiency and power output by forcing extra air into the combustion chamber. The key difference between a turbocharger and 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 and an exhaust valve.
