5.11.1. Features of a designThe lubrication system combined: the most loaded details are greased under pressure, and the others — or the directed spraying, or spraying of the oil following from gaps between the interfaced details. Pressure in the lubrication system is created by the gear oil pump with the internal trokhoidalny gearing of gear wheels established outside in a forward part of the block of cylinders and put in action from the forward end of a bent shaft.
The pump soaks up oil from an oil case of the engine through an oil receiver with the mesh filter and through a full-line oil filter with the filtering element from porous paper gives it to the trunk oil main located in a body of the block of cylinders on the left side. Channels of a supply of oil to radical bearings of a bent shaft depart from the trunk main. Oil to conrod bearings moves via the channels executed in a body of a bent shaft, and further on channels in cores of rods to openings in their top part through which it is sprayed on walls of cylinders and the bottom of pistons. The vertical channel of a supply of oil to cases of camshafts and to the top longitudinal oil canal connected by drillings in a block head to hydrocompensators of gaps in the valvate mechanism departs from the trunk oil main. Will screw the reducing valve limiting oil pressure in a head of the block of cylinders in a face part of the top longitudinal canal.
For lubricant of bearings of camshafts oil from the vertical channel comes to the central axial canals of camshafts through a radial opening in a neck of the third bearing and is distributed on them to other bearings.
Cams of the camshaft are oiled which arrives from the central axial channels through radial openings in cams. Excessive oil merges from a block head in an oil case via vertical drainage channels.
