When an engine is stuck, it is not only delayed in use, but also requires high repair costs. Why is the engine holding tile? Many car owners only know because of the oil, but the specific reasons are not understood, in fact, in addition to the oil problem, there are other reasons.

Lubrication system.
1, poor engine lubrication conditions: engine holding tile, many cases because of poor lubrication, it is easy to engine heat load, high temperature and so on. If you can not select the appropriate level of oil in accordance with the requirements, can not provide good lubrication for the axle tile, there will be an abnormal wear of the axle tile, coupled with a long period of time to run the eventual holding tile failure.
2, oil viscosity is too large: choose the regular oil is very critical, but also need to pay attention to the viscosity level of the oil when choosing, if the viscosity of the oil is too large, it will lead to poor fluidity of the oil, can not take away the heat of the axle shaft tile, resulting in higher axle shaft tile temperatures, but also increase the operating resistance of the moving parts of the engine.
3, the oil viscosity is too small: if the oil viscosity is too small, the engine is not easy to form a film when running, this will accelerate the wear of the alloy layer of the axle tile, when the wear to a certain extent, it will lead to the engine hold tile.

4, the oil pressure is too low: engine oil pressure if too low, will lead to the crankshaft and the flow between the axle tile is reduced, can not form a normal lubricant film, and ultimately lead to wear and tear or even damage to the axle tile. There are many reasons that affect the low oil pressure, such as low viscosity of the oil, the oil pump works abnormally will cause the oil pressure is too low.
5, poor oil filter quality: oil filter is also very critical, poor quality filter element can not be very good impurities filtered out, so that the impurities in the oil increased, and some poor filter element and even filter paper detachment, resulting in filter blocking, ultimately leading to impurities in the oil can not be filtered out of the hair, resulting in poor engine lubrication conditions, resulting in the engine hold tile.

Avoid burst tile, operation and maintenance is very critical
1, low-temperature start into the full load: engine low-temperature just start is the worst lubrication conditions, if the engine starts to enter the full load operation, the oil temperature does not rise, can not provide good lubrication will lead to abnormal wear and tear of the axial tile, a long time is very easy to lead to the engine holding tile.
2, often boring car, drag gear driving: in the actual vehicle driving, many drivers used to stew car, drag gear driving, in fact, this is a very bad habit. This operation will increase the burden of the shaft tile, bogging down, dragging gears when the engine speed is low, the oil pump can not be to the normal working speed, this time the oil pressure will be very low, the same will also appear in the engine hold tile risk.

3, buy genuine oil, cartridge: now on the market for the oil is mostly multi-grade oil, can basically meet the needs of the use of card users. When choosing motor oil, you should strictly follow the provisions of the vehicle instruction manual, choose the right level, viscosity of the oil. At the same time should also choose genuine oil filter, a good oil filter can filter out impurities in the oil, to maintain the lubricating quality of the oil, but also regularly replace the oil!

Assembly needs to be careful Shaft tile assembly should be reasonable
1、Insufficient preload height of axial tile assembly
Some engine hold tile failure, the reason is not enough preload height of the assembly of the axle shaft tile. If the preload height of the axle shaft tile is not enough, will make the axle shaft tile and sit on the body of the sitting hole fit is not enough, is not conducive to the heat dissipation of the axle shaft tile, thus leading to the axle shaft tile bite dead, the axle shaft tile rotating in the sitting hole, resulting in the seat of the axle shaft tile abnormal abrasion, the rotation caused by the oil hole clogging, the axle shaft tile temperature rises until the burnt out holding the tile faults.
2、The preload height of the axle shaft tile is too big
If the preload height of the axial tile is too large, it will also cause the holding tile. Shaft tile preload height is too large in the assembly will lead to shapely shaft tile, the surface of the shaft tile wrinkled, shaft tile and the crankshaft clearance is destroyed, ultimately leading to hold tile failure.
3、The assembly clearance of the axle shaft is too small
If the assembly clearance is too small, it will lead to insufficient oil to provide lubrication to form an oil film, when the crankshaft rotation will be due to friction, resulting in axial tile line hair, and in serious cases, there will even be axial tile melting and the crankshaft holding dead.

How to avoid bursting tile operation and maintenance is very critical
01, low-temperature start into full load
Engine low-temperature just start is the worst lubrication conditions, if the engine starts to enter the full load operation, the oil temperature does not rise, can not provide good lubrication will lead to abnormal wear of the axial tile, it is easy to lead to the engine holding tile.
02, often bogging down, dragging gear
Many drivers are accustomed to stalling the car, dragging gears to drive, in fact, this is a very bad habit. This operation will increase the burden of the axial tile, bogging down, dragging gears when the engine speed is relatively low, the oil pump can not be to the normal working speed, this time the oil pressure will be very low, the same will also appear in the engine hold tile risk.
03, buy genuine oil, filter element
The oil on the market is mostly multi-grade oil, which can basically meet the needs. When choosing motor oil, you should strictly follow the provisions of the vehicle instruction manual, choose the right level, viscosity of the oil. At the same time, you should also choose a genuine oil filter, a good oil filter can filter out impurities in the oil, to maintain the lubricating quality of the oil!
Generally speaking: there are only two special cases that may cause serious axle shaft tile failure due to oil factors.
(1). Winter engine temperature is too low, so that the fuel atomization is not good, incomplete combustion of fuel down the cylinder wall into the oil pan to dilute the lubricating oil, can also cause “burned holding shaft”.
(2). Due to cooling water infiltration into the oil for a long time, resulting in oil emulsification, deterioration, viscosity is completely lost, in the shaft and tile surface can not form a film of oil, resulting in more serious dry friction.

1, lubricating oil can add more, just add without replacement 
Too much lubricating oil is a negative impact, because too much lubricating oil from the cylinder and piston clearance into the combustion chamber combustion formation of carbon deposits. These carbon deposits will increase the engine compression ratio, increase the tendency to produce shock; carbon in the cylinder is red hot state is also prone to cause premature combustion, such as falling into the cylinder will intensify the wear and tear of the cylinder and piston, but also to accelerate the pollution of lubricating oil. Secondly, too much lubricant increases the crankshaft connecting rod stirring resistance, so that fuel consumption increases. The amount of lubricating oil should be controlled in the oil gauge between the upper and lower scale line is good.
Lubricating oil in the process of use, due to pollution, oxidation and other reasons the quality will gradually decline, while there will be some consumption, so that the amount of reduction. At this point, if you only add lubricant is not to ensure the quality of oil, can not fully compensate for the loss of lubricant performance, only to make up for the lack of oil quantity.
2, domestic equipment blindly use imported oil
Some owners believe that imported oil must be better than domestic oil, so the domestic equipment, especially the new equipment on the use of imported oil. Unbeknownst to them, this is often not worth the loss, there will be many disadvantages. If the blind use of imported oil, the engine will be in the normal operating temperature of the oil is too thin so that the oil pressure is low, and even up to the specified working pressure, can not meet the needs of normal lubrication, so that the engine wear increased.
3, pay attention to the additives in the lubricating oil
Lubricating oil is most concerned about the balance of the formula to protect the full play of various properties. Self-added other additives not only can not bring additional protection to the equipment, but easy to react with the chemical substances in the oil, resulting in a decline in the overall performance of the oil. In fact, the real quality of the lubricant is equipped with a variety of engine protection function of the finished product, the formula already contains a variety of additives, is not necessary to add their own.
4, do not know when to change the oil
Some car owners think, when the lubricant becomes black, the oil change, in fact, this understanding is not comprehensive. Automotive lubricants are generally clean decomposition agent, this decomposition agent will be adhered to the piston on the film and black carbon washing down, and dispersed in the oil, reduce the engine high temperature precipitates generated, so the lubricant after a period of time the color will become black, but this time the oil has not been completely degraded, that is, you can continue to use, and does not need to be replaced. Did not add a cleaner decomposition agent lubricant in the color black when the instructions have been deteriorated, this time it is necessary to replace.
5, the greater the viscosity of the lubricant the better
Many owners will think that the greater the viscosity of the lubricant the better, in fact, this idea is not right, because the greater the viscosity, the friction surface of the moving parts of the oil film between the thicker. Thick oil film, although it is conducive to preventing friction surface wear, but then the friction resistance is also large, power loss increases. Experiments have proved that the viscosity of the lubricating oil exceeds the requirements, but also increase the wear of the parts, because the wear of the parts of about 2/3 of the amount produced in the early start. Therefore, the viscosity of the engine lubricating oil is not the greater the better, but should be in the conditions to ensure lubrication, try to choose a small viscosity of the lubricant. Because the low viscosity of the lubricating oil is one of the current measures to save fuel.
