System of greasing of the engine
The general data
Engines are equipped by circulating system of 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. On an exit from the oil pump is редукционный the valve. At increase of pressure above the established value the valve opens also an oil part merges back in the pallet картера.
Through the central aperture of the oil filter oil arrives directly in the main channel. At a contamination of the oil filter перепускной the valve directs oil to system not filtered.
From the main oil highway channels for greasing of bearings of a cranked shaft branch off. Through inclined apertures in a cranked shaft oil moves to шатунным to bearings. For cooling of pistons oil is injected on them from below through atomizers.
Simultaneously oil through vertical galleries reaches heads of cylinders and arrives for greasing of bearings of camshafts and elements клапанных system mechanisms газораспределения.
Depending on capacity of the engine oil can be cooled in additional маслоохладителе, located sideways, at the case of the oil filter and included in a contour of system of cooling of the engine.
