A turbocharger, commonly referred to as a turbo, is a turbine-driven forced induction device designed to enhance the efficiency and power output of an internal combustion engine by introducing additional air into the combustion chamber.
This enhancement over a naturally aspirated engine arises from the turbocharger's ability to compress and deliver a greater volume of air—and correspondingly more fuel—into the combustion chamber than atmospheric pressure can provide alone.
The primary objective of a turbocharger is to improve engine efficiency by increasing the density of the intake gas, typically air. This increase allows for more power generation during each engine cycle.
In addition to boosting power, a turbocharger can also enhance fuel efficiency without necessarily increasing output. This is accomplished by recovering waste energy from the exhaust gases and redirecting it into the engine intake. By harnessing this otherwise wasted energy to augment the mass of air entering the combustion chamber, the engine can optimize fuel combustion before the exhaust phase begins.
