  4. MAINTENANCEOF MAJOR COMPONENTS 3) Operating principle The turbocharger is a system designed to make use of the engine exhaust gas energy to charge high- density air into the cylinders, thereby to increase the engine output. 4.4.2 General descriptions The engine output is determined by the fuel delivery volume and engine efficiency. To burn the supplied fuel completely to change into effective power for the engine, the volume of air enough to burn the fuel completely should be supplied into the cylinders.
