Add oils:

1 - anti-oxidant additives.
2 - Extras sealing foam.
3 - Extras corrosion-proof.
4 - Extras improve viscosity coefficient.
5 - Extras cleaning.
6 - Extras rust-proof.

Moving parts that require lubrication: -
 - Attached chairs axes.
 - Benz piston.
 - The walls of the cylinders.
 - Chairs camshaft.
 - Leverages column valves.
 - Evidence valves.
 - Timing gears.

Lubrication method:
The method oiling forced most common way and will talk about it in detail and the pump is used to take their movement through the pinion particular problem on the camshaft These pump to withdraw oil from the pot of oil (cover crankcase) through strainer wire and then you pay by pressing a certain prescribed pressure regulator to pass to the candidate and from oil to the main tube subdivided into several branches up to the corridors of oil to lubricate moving parts engine and these branches are:

- Branch to set the oil pressure in the circuit while the engine is running.
- Branch to chairs fulcrum column annex.
- Branch to chairs camshaft.
- Branch to Jacks valves column top cover cylinders and then stalks pay valves.
- Pass a special chair front of the facility or column chair camshaft timing gear lubrication.
Oil and flaking after passing these branches to the crankcase (oil tank) again.

A lubricating components:

1 -  Oil pan

 It receptacle that accumulates the lubricating oil engine and purpose that works reservoir for a certain amount of oil depending on the requirements of the engine and maintain the oil level so that it is consistent and appropriate for the pump during landing or the rise of heights so be base with two different levels also contains stopper unloading at the lowest point where can even dump the engine oil after the lifting or decode this plug.

 

2 - oil refinery:

 Is a wire mesh metal minute gaps placed in casing linking the bottom of the oil pump so that a suitable bottom pot oil to avoid capture mineral deposits generated during operation of the engine and that accumulate inside the container and thus operate the refinery to purify oil from exotic materials relatively large access to stream across the engine with oil.

3- Oil Pump

 Using several types of oil pumps in the group of lubrication for engine parts such as pump with feathers - pump rotor - pump with leg immersion - pump with gears which derive their movement usually on different kinds of camshaft engine and sometimes column annex and the purpose of the pump is pulling oil from container and then pay in lubricating distributor circle under particular pressure fits the necessary pressure for the oil to reach different parts of the motor and pump is supplied and fed into a pressure safety valve installed with oil at the exit hole.

 

4 - Oil Filter

 

 Riding in circles Engine lubrication are two main types of filters (filters) and purpose of the oil is suspended impurities minute reservations oil and prevent the passage of the Department of oiling up to clean engine parts moving decreases erosion and long life operation.

 Types:
Type I: -
Cover is a candidate or permanent container placed in filtration material are replaced alone without the enclosure or cover all 8000: 10,000 km so remains a candidate with a good performance for his job.

 Type II: -
Candidate is stainless parts for the casing material nomination as a single unit where alter completely and no substance nomination only and manufactures often material filtration fabric felt porous (cotton waste) confined between two sheets metal flimsies punched or layers of paper processing sheets thin metal separating between them poles or barriers to Thiar oil The granules impurities Inseparable him and deposition in the bottom of the cover.

Nomination of lubricating oil circuits:
1 - Department of micro-filtration of oil:
And where no two corridors separate oil related one candidate while related other chairs axes various engine where it passes part of the oil Alorad from the pump to bypass to the candidate to pass through material nomination minutes and then back to the oil tank mailbox facility after his nomination and purified to remain clean before turning or paid to motor axes chairs.
2 - Department of kidney filtration of the oil:
 And the passing of oil in a single lane where it passes the oil coming from the pump all through the filter of kidneys to oil to flow through the material nomination comes after purified chairs axes and contains candidate kidney on the valve to divert oil to allow Passes through the filter in case of clogging substance filtration exactly where opens the valve when increasing oil pressure set to pass the oil and complements its candidate without the nomination and thus prevents the valve uninterrupted oil chairs axes when clogged filtration material and important switch oil regularly with the candidate regularly in order to avoid what is happening as a result of poor filtration.

 Safety devices in lubricating circuits:
Provide lubrication circuits arrest (by clicking) iPods and means safety can protect the lubrication cycle of disruption and ensure the availability of oil and continuity for the performance of his duties in the engine lubrication of moving parts, namely:
1 - oil pressure regulator (valve security department).
2 - indicated mechanical oil pressure Oil Pressure Indicator.

  

Oil pressure regulator valve circuit security:
Its purpose is to keep the oil pressure remains constant search and appropriate access to the moving parts engine regardless of the temperature of the oil or the speed of rotation of the pump, which pay high pressure oil higher the rotational speed of the engine.

 Shown mechanical oil pressure:
Provide services oiling shown a special statement oil pressure proves on the dashboard so the driver can see and he may look if that happens malfunction or defect in the constituency to prevent the arrival of oil to moving parts engine and related this indicated a branch pipe major emerging from the oil pump.

How it works shown mechanical oil?
When a steady drumbeat of oil paid or CD from the pump to pipe compressed air trapped inside the tube towards the end closed the unique impact of air captivity according to the increased pressure and when separately this free end to the outside move with lever articulated to move sector dentate around the axis fulcrum to manage gear and with the index shows how much pressure oil on the scale shown.

Measure the oil level Oil Stick
Is a column metal long used to see the depth of the amount of oil inside the pot oil engine and enters this leg to the engine through a tube installed on the block cylinders where dive end measure within the oil and is listed signs show the oil level in the basin, and should be checked the oil level regularly before run the engine and must be the oil level on the scale between the two signs refer to the highest level and the lowest level of the oil is not recommended to run the engine if the oil is less or more than the required level.

  

  Crankcase Ventilation :

 
· To maintain the pressure within the crankcase and ensure that no amount of oil shortages and disposal of harmful fumes.

· To maintain the properties of lubricating oil to ensure good lubrication for engine parts and dispose of harmful substances generated during operation.

· Should not manage the engine at slow speeds for a long time until it reaches a temperature to operating temperature and then all of the water evaporates
 And the shipment leaked, and thus can get rid of them through the crankcase ventilation.

The crankcase ventilation means:
Containing circle air ventilation crankcase general slot to enter the air into the engine - slot exit of air from the engine - means air circulation between the slots and is used in ventilation modern engines tray attachment Court so called system ventilation system ventilation requirement for packet Positive Crank Case Ventilation and which is inserted stream ventilation air directly from the main candidate and who pays fumes accumulated attachment from the mailbox slot exit the box to the side tube especially related Bamozy or intake manifold to bring it back again to the combustion chambers with a mixture of air and fuel through ventilation valve positive crankcase.
