Charging, function

Forced induction is used to provide the engine with the appropriate boost pressure in all operating phases, thus increasing engine performance and engine 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 inlet, pre-compresses it, then passes it through the compressor outlet, the charge air pipe, the charge air cooler and the air intake manifold to the individual cylinders in the engine.

Controlling of the turbocharging takes place over the boost pressure control, which is described in a separate document:
