A turbocharger, or turbo (colloquialism), from the Greek "τύρβη" (mixing/spinning) is a forced induction device used to allow more power to be produced for an engine of a given size. The key difference between a turbocharger and a conventional supercharger is that the latter is mechanically driven from the engine often from a belt connected to the crankshaft. The benefit of a turbo is that it compresses a greater mass of intake air into the combustion chamber(s), thereby resulting in increased power and/or efficiency. Turbos are commonly used on truck, car, train and construction equipment engines. Turbos are popularly used with Otto cycle and Diesel cycle internal combustion engines. They have also been found useful in automotive fuel cells. Twincharger refers to an engine which has both a supercharger and a turbocharger.
