The boost pressure is controlled by the CDI control unit (N3/9) in line with the stored boost pressure map

The input parameters for the boost pressure control are:

Charge air pressure/temperature

Atmospheric pressure

Coolant temperature

Oil temperature

Engine load/rotational speed

Drive position

Air mass

The left boost pressure regulator (Y100) and right boost pressure regulator (Y100/1) attached directly to the left and right turbocharger are actuated by the CDI control unit (N3/9) by means of a PWM signal (pulse width modulation) and by means of a linkage determines the position of the guide vanes in the turbochargers (in line with the on/off ratio of the PWM signal).

The variable turbine geometry of the left and right turbocharger makes it possible to build up the boost pressure required for each engine operating point.

The turbine geometry of the left and right turbocharger is controlled through the boost pressure regulators by the CDI control unit (N3/9) so that the same air mass flow exists in the left and right inlet tract (measured by the hot film mass air flow sensors).
