Oil Supply System

Oil Supply System

When the lubrication system was developed, the most important objective was to reduce friction inside the engine even further. A series of measures such as the modified chain drive were implemented. In addition, improvements in the oil circuit have significantly reduced the oil flow rate.







Improvement measures:
- Modification of the sickle groove on the main bearing shell of the crankshaft from 180° to 150°
- Relocation of the oil feed bore in the camshaft bearings
- Halving of the flow rate through the piston spray nozzles
- Reduction in leaks from the camshaft controller incl. valves for camshaft control
- The oil supply system for the continuous camshaft controller has been decoupled from the cylinder head oil supply system (camshaft bearings and hydro elements). It was therefore possible to restrict the oil pressure in the cylinder head while simultaneously improving the connection between the cam - shaft control valves and the oil supply system.
