The function of a turbocharger is to use the exhaust gas energy of an internal combustion engine (which would otherwise be wasted) to drive a turbine wheel and hence a compressor. The compressor increases the pressure and density of the charge in the engine cylinder, thereby increasing the power above that of a naturally aspirated engine.

Turbocharging has been shown to be the most successful method of reducing cost, weight and space requirement of diesel engine installations, and is recognised as a reliable method of improving their performance, efficiency and fuel consumption.
