For charging, the flow energy of the exhaust gases are used to drive the turbocharger.

The cylinder charge efficiency is improved as a result of charging.

The engine torque and power output are boosted as a result.

The turbocharger sucks in fresh air and compacts this by means of a high rotational speed of the turbine wheel. The resulting high volume flow is further compressed in the charge air pipe.

The boost pressure positioner adjusts the guide vanes in the turbocharger and thus regulates the boost pressure (volume flow).

The charge air cooler then cools down the charge air heated by compression and passes the air on to the charge air distribution pipe. The charge air is then passed from the charge air distribution pipe to the inlet ducts for individual cylinders.

The boost pressure is detected by the boost pressure sensor and the charge air temperature by the charge air temperature sensor and transmitted to the CDI control unit (N3/9) in the form of voltage signals.
