7.4. Turbocharger
The turbocharger is a system designed to make use of the engine exhaust gas energy to
charge high-density compressed air into the cylinders, thereby to increase the engine output.
As explained, the compressing of air to supply into the cylinders is called “Supercharging” and
the making use of the energy of exhaust gas discharged from the combustion chamber to
charge the compressed air into the cylinders is called “Turbocharging”.
