Oil pressure regulating valve: Notes

For the volume-flow-controlled oil pump, the oil pressure control valve has been integrated.

The use of characteristic map control for the volumetric-flow-controlled oil pump enables oil supply in line with requirements and a reduction in the average pressure level in the oil circuit. The oil pressure control valve enables the Digital Engine Electronics (DME) to control the fuel delivery rate individually.

NOTE: The basic function of the oil pressure control valve is described. The installation location shown via the hotspot on the wiring diagram of the diagnosis is essential to ensure that the installation location is correct!

The engine has a volume-flow-regulated oil pump. This volume-flow-controlled oil pump only delivers exactly as much oil as each operating range of the engine requires.

For the volume-flow-controlled oil pump, the oil pressure control valve is integrated. The control via a characteristic map influences the oil pressure in the controllable oil chamber. Two valves are involved in the oil-pressure control:
