3.4. Greasing system


System of greasing of the engine

The compulsory system of greasing includes the polnopotochny oil filter and the shesterenny pump. The pump takes away oil from the pallet which passes through the reception mesh filter, and submits it to greasing system via the oil filter.

On the engine the polnopotochny oil filter with a cardboard filtering element is established. In system it is provided by the roundabout suited the filter on which oil arrives to rubbing details of the engine at a contamination and increase сопротив the line of the oil filter. From the filter oil goes to the trunk oil main from which oil channels of radical bearings depart.

In rods small openings through which oil is sprayed on internal walls of cylinders for обеспече a niya of greasing and in pistons for their cooling are executed. The vertical channel departs from the trunk oil main for an oil supply to cases of cam-shafts. Oil arrives to the central axial canals of cam-shafts through radial openings in necks of the third bearing and is distributed to other bearings. The vertical channel is connected with the top longitudinal oil channels drilled from the left and right side in a head of cylinders.

On these channels oil arrives to hydrojacks of gaps of inlet and final valves. Cams of cam-shafts are oiled, arriving from the central channels through radial drillings in cams. Excessive oil merges from the gazoraspredeleniye mechanism in the oil pallet through the vertical drainage openings located about inlet valves 1, 2 and 3rd of cylinders, see fig. System of greasing of the engine.
