The scheme of a contour of circulation of oil

Engines BMW have greasing under pressure. The oil pump sucks in oil through a grid from the pallet картера and submits it under pressure to system through the oil filter. Through the central axis of a filtering cartridge the cleared oil arrives in the main oil highway. If the filter is littered, oil through перепускной the valve arrives directly in system without clearing.

After the oil filter it is established редукционный the valve supporting pressure nearby 4 bar. At increase of pressure of oil the valve opens and merges oil in the pallet картера.

From the trunk main there are branches for greasing of bearings of a cranked shaft. Through inclined channels oil moves to шатунным to bearings and therefrom to the bottoms of pistons and to cylinders.

Simultaneously impellent oil through vertical tubes moves in a head of cylinders, greasing there bearings of camshafts, jacks клапанных backlashes and directing valves. Throttle channels provide giving of necessary quantity of oil for greasing listed above elements in a head of cylinders.

Besides, oil arrives to a chain of a drive of the mechanism of distribution with натяжителем and at the petrol engine to приводной chains of the oil pump.
