Hyundai Getz>> The engine>> Greasing system
Features of the device
Greasing system the combined: разбрызгиванием and under pressure. Under pressure support of camshafts are greased radical and шатунные bearings. The system consists from oil картера, шестеренчатого the oil pump with маслоприемником, полнопоточного the oil filter, the gauge of pressure of oil and oil valves.
The oil pump takes away oil from the oil pallet of the engine and submits it to the oil filter. From outside forcings of the oil pump is перепускной the valve. At too high pressure of oil the valve opens also an oil part flows down back in the engine pallet.
Through the middle of a filtering element of the oil filter pure oil arrives in the main oil highway. At a contamination of the filter bypass the valve located in the case of the oil filter, submits not filtered oil directly to the main oil highway. In a branch pipe of the oil filter there is a return valve which interferes with a devastation of oil channels and hydraulic pushers of valves of the engine. Channels depart from the main oil highway for greasing of bearings of a cranked shaft. Through inclined apertures in cranked to a shaft oil moves to шатунным to bearings, and therefrom is sprayed on piston fingers and cylinders. Simultaneously on ascending channels oil moves in a head of the block of cylinders and provides greasing of bearings of a camshaft and work of hydraulic pushers.
The oil expense
Speaking about the oil expense in an internal combustion engine, we mean only that its quantity which is spent at combustion (the expense on charcoal fumes). At all it is not necessary to confuse the expense of oil to loss of oil because of негерметичности the oil pallet, a cover of a head of the block of cylinders and so forth the Normal expense of oil arises owing to small amount combustion in cylinders, and also because of tap of the rests of combustion and particles of products of deterioration. Oil grows old under the influence of a heat and pressure in engine cylinders. On the oil expense render a great influence and external factors, such as a driving manner, and also accuracy of manufacturing of details of the engine.
As much as possible admissible at operation the oil expense can make 1 l on 1000 km of run.
On reaching a label «MIN» it is necessary to add oil (the volume of added oil should not exceed 1).
Choice of oil for system of greasing of the engine
All-weather oil is applied to greasing of engines of cars Hyundai. It can be used both in winter, and in summertime. A basis of all-weather oils are liquid seasonal oils (for example, a viscosity class 15W). At the expense of so-called thickeners oil is stabilised in a hot condition, therefore for each condition necessary lubricant properties are provided. The letter «W» on classification SAE specifies that the given oil can be used in the winter.
Legkohodnye oils represent all-weather oils with antifrictional additives, at their application the economy of fuel to 2 % is possible. Legkohodnye oils have low viscosity (for example, 10W-30). They demand a special basis (synthetic oils).
Recommended class of quality of oil on API – not more low SG or SH.
Recommended class of viscosity of oil on SAE – depending on the expected temperature of air before the following replacement of oil.
Check of level of oil
Establish the car on an equal horizontal platform.
Start up and warm up the engine.
|
THE NOTE
After long idle time of the car warm up the engine approximately within 20 minutes
|
Stop the engine, wait for 2-3 mines and check up oil level.
Oil level should be between labels маслоизмерительного щупа. At decrease in level below a label «L» add oil to a label «F».
Be convinced that oil pure, without impurity of a cooling liquid or gasoline and has demanded viscosity.
|
THE PREVENTION
On the cars equipped with engines with каталитическим by neutralizer, it is necessary to watch that oil level on маслоизмерительному щупу was not above maximum. If in the car with каталитическим neutralizer too much oil is filled in, it is necessary to remove its surplus from картера means plum or отсоса (the special vacuum pump), otherwise not burnt down oil will get into system of release of the fulfilled gases and can destroy каталитический neutralizer.

Oil replacement in the engine
Start up and warm up the engine to normal working temperature.
Stop the engine.
Remove a stopper маслоналивной mouths, turn away a stopper маслосливного apertures (on the oil pallet), as is shown in fig. 2.127, and merge oil from the engine.
Wrap a stopper and tighten its moment 35–45 Н·м.
Fill in in the engine fresh oil through a bulk mouth.
Establish a stopper маслоналивной mouths.
Start up the engine and allow to it to work.
Stop the engine, check up level of oil and if necessary restore it to norm.
Capacity of system of greasing of the engine, l:
Working volume of 1,1 l:
2,8 (without replacement of the oil filter);
3,1 (with replacement of the oil filter)
Working volume 1,3; 1,5 and 1,6 l:
3,0 (without replacement of the oil filter);
3,3 (with replacement of the oil filter)
Replacement of the oil filter
All engines Hyundai equip with demountable oil quality filters which are recommended to be used for replacement by all cars. Filters available on sale are various on quality. For maintenance of effective maintenance service it is necessary to use only quality filters. Before installation of the new filter remove with привалочной surfaces of the block of cylinders the rests of a rubber lining of the old filter.
Turn away the oil filter by means of a special key.
Put pure engine oil on a rubber lining of the new filter (fig. 2.128).
Wrap the oil filter and tighten its moment 12–16 Н·м (fig. 2.129).
Start up the engine and be convinced of absence of leaks of oil.
Stop the engine, check up level of oil and if necessary finish it to norm.

That it is necessary to know at oil replacement
First, it is recommended not only to give to old oil completely to flow down but also to turn a cranked shaft of the engine on 5–7 turns, to remove the remained oil from oil highways. It is useful to wash out also the engine (for this purpose apply special oil to washing) during 20–25 mines, thus the engine should work in an idling mode.
Changing oil, always it is necessary to replace and the filter. Old though and washed out, will be «as a fly in the ointment».
Oil should be changed indoors where there is no dust and a wind.
At check of level of oil in картере the engine the rag which wipe маслоизмерительный щуп, should be pure. Even, apparently, the insignificant particles of the dust which has got to the engine, considerably reduce term of its service.
At oil replacement change also a lining of a stopper of a drain aperture in the oil pallet of the engine, and also the case of the oil filter (if it is established). The lining is included into the complete set of the oil filter.
After oil replacement it is useful to fix car run, replacement date, oil mark that at its subsequent replacement or доливке was less problems.
It is not necessary to be afraid of that oil will darken already after 1000 km of run. It testifies only that it "works" correctly – keeps in itself a deposit and washes surfaces of details.
