Burn off the remaining engine oilIt's a cliché problem, the new oil starts to burn the oil, or the viscosity of the new oil is not suitable, too thin, the oil film is too thin, can not be well attached to the parts, resulting in a bad seal, or it is to use jujube to fake engine oil, and the oil quality is poor. Now fake engine oil is impossible to prevent. I only use imported engine oil, or to ensure that there are no fakes, the experience is good, like GT magic red engine oil, just entered the domestic market, the channel control is very strict, the pace of expansion is slow, can ensure that it is real engine oil.
The oil that has just been changed is equivalent to destroying the balance of the original lubrication system, so it is necessary to adapt, especially the poor engine oil used before, and now the good engine oil is very clean, and it will clean up the carbon deposit.
It is possible to break the tightness of the roll, which will lead to the burning of the engine oil. As long as you insist on using it, it is best to use German GT engine oil, this will not be the case, because his high temperature stability is very good, and the high temperature viscosity value is very high, which is higher than that of fully synthetic, because he is a PAO base oil. Target.

This is a very normal thing to bury in the past, the oil that has just been replaced by the bend search is equivalent to destroying the balance of the original moist accompaniment system, so it is necessary to adapt, especially the poor engine oil used before, and now the good engine oil, the cleanliness of the good engine oil is very strong, and it will clean up the carbon deposits, which may destroy the sealing and lead to the burning of the engine oil. As long as you insist on using it, it is best to use German GT engine oil, this will not be the case, because his high temperature stability is very good, and the high temperature viscosity value is very high, which is higher than that of fully synthetic, because he is a PAO base oil. You can try this instead.

Burning engine oil is a common problem, change the new engine oil and start to burn the lead hole with the engine oil, either the viscosity of the new engine oil is not suitable, too thin, the oil film is too thin, can not be well attached to the parts, resulting in the sealing of the Huai stupid, or the use of fake engine oil, poor oil quality. Now the trembling head in the fake engine oil is impossible to prevent. I only use imported engine oil, or to ensure that there are no fakes, the experience is good, like GT magic red engine oil, just entered the domestic market, the channel control is very strict, the pace of expansion is slow, can ensure that it is real engine oil.

The reason why the car burns oil.
1. Burning engine oil in a cold car: When the temperature of the car is not completely warmed up, the engine exhaust pipe emits a lot of blue smoke, but it is normal after the car is heated. This phenomenon is caused by the aging of the valve oil seal.
Due to the decrease in temperature, the valve oil seal of the rubber material is stiff and cannot be completely sealed, and the oil leaks from the valve into the combustion chamber and burns. Solution: Remove the engine cylinder head and replace the valve seal.
2. Hot car burns engine oil: After the car reaches the normal temperature, the exhaust pipe still emits blue smoke, which indicates that the piston ring has a poor seal. Due to the poor sealing of the piston ring, the oil directly enters the combustion chamber through the piston ring leakage under the action of the oil pump, and there is a phenomenon of blue smoke from the exhaust pipe.
There are several reasons for this phenomenon, such as: material aging, carbon deposition jamming, excessive wear of cylinder liners, etc. Workaround:
According to the normal operation method, the engine needs to be lifted down for overhaul work. The repair time is about 2-4 days. Depending on your car, the cost is mainly in the accessories.
In addition, there is another way to deal with it: if it is determined that the oil is burning in a hot car and it is not very serious (for safety reasons, the cylinder pressure test can be carried out first), the oil pan can also be removed directly, the piston can be directly taken out, and the piston ring can be replaced, so that the cost and time are similar to the first solution.

Summary. Hello, the engine has been replaced with four sets and the oil is burned for the following reasons:
Hello, the engine has been replaced with four sets and the oil is burned for the following reasons:
My tractor has just been replaced, and the oil is burning, and the more it burns, the more it burns more than one acre, and two pots are burned.
1. The phenomenon of gas channeling and oil burning: Jane and 1"Three filters"failure, so that dust impurities into the cylinder to form abrasive wear; 2.
When the engine combustion is insufficient, excessive carbon deposits are produced and abrasive wear is formed; Blocking Lu staring 3The lubrication system works poorly and cannot form a lubricating oil film, resulting in poor lubrication between the friction pairs; 4.After replacing the four matchings, the run-in was not carried out in strict accordance with the technical requirements of the engine; 5.
In the assembly process, the components are not cleaned, and there are dust and other impurities caused by abrasive wear; 6.The lubricating oil is of poor quality and cannot form a lubricating oil film, or the formed oil film is easy to break, resulting in poor lubrication between the friction pairs.
Second, the reason for the piston ring 1The vertical quality of the piston ring does not meet the requirements, which is easy to cause fracture or early wear of the piston ring; 2.insufficient elasticity of the piston ring or too large finch skin gap between the openings; 3.The flatness of the piston ring is out of tolerance or the deflection does not meet the requirements.
Three thought mold, piston reason 1The piston ring groove is out of tolerance; 2.The piston ring groove is too wide; 3.The head or skirt of the piston is on the small side; 4.The piston material does not meet the requirements, resulting in piston ring bank fracture or early wear.
Fourth, the reason for the cylinder liner 1The diameter of the cylinder liner is too large; 2.Liner cylindricity or taper is out of tolerance; 3.The roughness of the inner surface of the cylinder liner is out of tolerance.
5. Assembly reason 1The piston ring is reversed; 2.Causing the piston ring to twist, deform or break during assembly; 3.
The opening of the piston loss wheel ring was not sold according to the assembly requirements; 4.The credit adjustment of the combustion system is not good, and the carbon deposit generated when the combustion is not sufficient is too much, resulting in abrasive wear; 5.Improper adjustment of the injection advance angle of the injector causes the engine to produce abnormal combustion, excessive carbon deposits, and abrasive wear.
Sixth, other reasons for the characteristics of Chunda: four supporting components and installation and use process are no problem 1The oil scale is incorrect, resulting in the oil level in the oil pan being too high; 2.
The crankcase ventilation valve hole is blocked, resulting in too high demolition, lubricating oil being pressed into the combustion chamber, and at the same time, it will also cause exhaust gas to channel upward; 3.The clearance of the crankshaft spindle diameter bearing is too large, and too much oil splashes on the surface of the cylinder liner and the pickpockets enter the combustion chamber vertically; 4.The oil return hole of the cylinder head is blocked, so that the excess oil cannot return to the oil pan and is consumed, resulting in oil loss; 5.
The oil channel is not tightly sealed, so that the oil leaks; 6.The gap between the valve stem and the valve guide is too large, which causes the oil to enter the combustion chamber and burn the oil.
If the engine is replaced with four sets and still burns the engine oil, you need to eliminate and check from these six aspects one by one.
There are many reasons, so at this time you still have to be patient to rule out and check! Even when you go to a repair shop, you have to check it like this!
It's hard, so I suggest you go to the forum and check it out.

In cars, belts are a very important thing. It is usually the main medium connecting the crankshaft of the automobile engine and the air conditioning compressor, generator and water pump on the car. When the automobile engine is in operation, the precise control of the intake and exhaust of the car can only be achieved through the operation of the timing belt. >>>More

Hello! If you can't catch fire, you check it out.
1. Check the valve clearance, if it is not right, you need to adjust it, if your car is DHOC, you have some annoyance. Valve gaskets are not easy to find. >>>More
