Oil supply: Notes

The engine has a map-controlled oil pump. Oil is supplied according to requirements which means that only the amount of engine oil actually used is supplied. The volume-flow-controlled oil pump reduces fuel consumption by up to 1%. This oil pump builds up oil pressure which initially routes oil through an oil duct to the oil filter. from where it is supplied to the crankshaft bearings and connecting rod bearings via an oil duct. An additional main oil duct fills the vertical line to the cylinder head. An oil duct in the cylinder head leads to the VANOS solenoid valves, chain tensioner, hydraulic valve clearance compensating elements and vacuum pump.
