Greasing system - the general informationThe device and functioning principle
The oil pump роторного type consists of the case in which internal and external gear wheels are located. At the expense of rotation of gear wheels oil giving to engine knots is provided. The internal gear wheel (rotor) is interfaced directly to a pin of a cranked shaft and, in turn provides a drive of an external gear wheel (rotor). The pressure is provided at the expense of change in a course of rotation of volume межроторной cavities and supported at demanded level with the help редукционного the valve returning surplus of oil back on an input of pump assemblage.
Contour of system of greasing of engine SOHC
From the pump oil on the channel located in the bottom part of the right semiblock, arrives in полнопоточный the oil filter, whence moves in the main oil gallery of the right semiblock and is distributed on internal components of the engine.
Besides the block, oil under pressure moves also in heads of cylinders for greasing of components клапанных mechanisms. The quantity of arriving oil is regulated by means of the sprays established in oil channels. In an axis коромысел a drive of valves are built in редукционные the valves providing deduction of pressure of oil in set limits, guaranteeing serviceability of functioning of hydraulic proof-readers клапанных backlashes.
The pallet картера the engine is supplied маслоотражательной by a plate providing stabilisation of the account characteristic of the oil pump.
Unlike engines SOHC, on the given engines oil moves from the pump at first in маслоохладитель and only then in полнопоточный the filter.
Contour of system of greasing of engine DOHC
From the filter oil arrives in the main oil galleries of the left and right semiblocks.
The reduktsionnye valves regulating pressure in highways of heads of cylinders are located in separate маслотоках, uniters of a nest of hydroproof-readers клапанных backlashes.
Forward bearings of camshafts are oiled, arriving on the channels laid inside actually of shaft.
Полнопоточный the oil filter
Полнопоточный the oil filter has not folding design.
Design полнопоточного the oil filter
The filtering element is executed from the goffered cardboard, in assemblage is built in перепускной the valve.
The pallet картера and маслозаборник
The pallet картера fastens to the engine block from below, the interfaced surface is condensed with liquid hermetic. Маслозаборник it is equipped by the mesh filter preventing hit in system of greasing of sawdust and other firm extraneous particles. The reception knot маслозаборника is located in the central part of the pallet картера. On a connecting tube oil is soaked up from the pallet in the oil pump located in the left semiblock.
The maslootrazhatelnye partitions established in the pallet and the bottom part картера of the engine, serve for stabilisation of level of oil, and also provide additional rigidity to the pallet.
The gauge of pressure of oil
Design of the gauge of emergency pressure of oil
The gauge of emergency pressure of oil is located in the top part of the block of cylinders. The gauge design is presented on an accompanying illustration.
At inclusion ignition, demanded lifting of pressure of oil yet is not provided, the diaphragm of the gauge under the influence of a spring moves towards the block of cylinders and closes electric contacts of assemblage therefore there is an operation built in in a combination of devices of a control lamp.
After engine start when pressure of oil exceeds value 14.7 кПа, the gauge diaphragm moves to an opposite side therefore contacts are disconnected also a control lamp dies away.
