Boost pressure control function

21.8.95

Task

 Controlling the boost pressure in line with the operating state of the engine

 Controlling boost pressure in line with the map in the DFI control module (N3/8)

Function

The boost pressure is controlled by the DFI control module (N3/8) in line with the boost pressure map and the pressure sensor (B28). The boost pressure control vacuum transducer (Y31/5) is actuated by the control module with a variable current and supplies a controlled vacuum to the boost pressure control vacuum unit (110/10).
