Forced induction is used to provide the engine with the appropriate boost pressure in all operating phases, thus increasing engine power and torque.

In turbocharging, the flow energy of the exhaust gases is used to drive the turbocharger.

The turbocharger draws in fresh air at the compressor intake, compresses it and directs it through the compressor outlet, the charge air pipe, the charge air cooler and the air intake manifold to the engine's individual cylinders.

Turbocharging is regulated by the boost pressure control.
