5.11.1. Features of a design

Greasing system the combined: the most loaded details are greased under pressure, and the others — or directed разбрызгиванием, or разбрызгиванием the oil following from backlashes between interfaced details. Pressure in greasing system is created шестеренчатым by the oil pump with internal трохоидальным the 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 cranked shaft.

The pump soaks up oil from oil картера the engine through маслоприемник with the mesh filter and through полнопоточный the oil filter with a filtering element from a porous paper submits it to the main oil highway located in a body of the block of cylinders on the left side. Channels of a supply of oil depart from the trunk main to radical bearings of a cranked shaft. Oil to шатунным to bearings moves through the channels executed in a body of a cranked shaft, and further on channels in cores of rods to apertures 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 departs from the main oil highway to cases of camshafts and in the top longitudinal oil channel connected by drillings in a head of the block with hydrojacks of backlashes in клапанном the mechanism. In a face part of the top longitudinal channel will screw редукционный the valve limiting pressure of oil in a head of the block of cylinders.

For greasing of bearings of camshafts oil from the vertical channel arrives in the central axial channels of camshafts through a radial aperture in a neck of the third bearing and is distributed on them to other bearings.

Camshaft cams are oiled, which arrives from the central axial channels through radial apertures in cams. Excessive oil merges from a block head in oil картер through vertical drainage channels.

Oil replacement in the engine and the oil filter is described in section 4 "Maintenance service" (oil Replacement in the engine and the oil filter see), removal and installation of the oil pump, and also its repair — in the given subsection.
