Ask the master, what is going on about burning engine oil in the car?

Reasons for burning engine oil: long-term unclean oil circuit, untimely replacement of antifreeze, and too long oil service cycle.

The harm of burning engine oil: it will continue to generate greater carbon deposits, which will seriously pull the cylinder. The three-way catalytic converter is completely damaged in the poor combustion exhaust gas,,, and the continuous life-sustaining oil will eventually cause the engine to burst the cylinder.

The three points of the car that burn the engine oil will inevitably occupy one point, and the most important point is the high temperature caused by the oil circuit not being effectively cleaned.

Causes of piston ring seizure.

The oil used for the stuck piston ring will be caused by the oil scraping not clean and remaining on the cylinder wall, causing the oil to participate in combustion and burn the oil. Among them, the cylinder wall will be seriously worn due to the delay in processing, and the engine will have to be disassembled.

In fact, the treatment principle of piston ring stagnation should start from the oil circuit, the reason for the stagnation is the beginning of the oil circuit, the oil bearing temperature is 110 degrees, and the high temperature caused by the long-term unclean oil circuit makes the oil at a temperature of 120 degrees or higher for a long time, so that the oil will be exhausted in advance, the small hole of the oil ring is very small, and the oil inside will be dried and scabbed for a long time, and a cylinder stuck is 5000 kilometers of a liter of oil, at this time, the working conditions of other cylinders will also begin to be bad, and soon the 4 cylinders will be stuck. It becomes a liter of engine oil for 1000 kilometers or even hundreds of kilometers. Therefore, in order to solve the problem, we must start from the root oil circuit, which is the way to remove the root.

This kind of car burning engine oil is very easy to do, first check the exhaust valve to see if there is a problem, and then see if the cylinder wall wear is serious, there is no problem, it must be caused by the piston ring stagnation, because there is no cylinder wall wear is not required to overhaul.

The problem of burning engine oil caused by piston ring stagnation is a phenomenon that occurs in most oil-burning vehicles. Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, PNF non-destructive repair technology has completely gotten rid of the technical shackles of the operation of the auto repair shop, without removing a screw, the owner can operate it himself, and the piston ring is repaired and released during driving, and the effect is remarkable.

Identification method of burning engine oil:

1. Cool car burning engine oil: When you get on the car for the first time every morning, there will be a relatively thick blue smoke exhaust from the rear exhaust pipe. After a while, the blue smoke disappears, and there is generally no similar situation on the day.

2. Burn engine oil when accelerating: When the driver slams on the accelerator or steps on the accelerator when the vehicle is moving, a large amount of blue smoke is discharged from the exhaust pipe, and when the driver slams the accelerator when the vehicle is driving, the driver can see the blue smoke from the reflector on the exhaust pipe side.

3. Fill the vehicle with the phenomenon of "burning engine oil" with engine oil, let the owner go to the maintenance station to weigh the oil filter after driving 1000 kilometers, and then fill up the engine oil, and then let the owner drive 1000 kilometers. Repeated 3 times, to obtain an average value, after the run-in period of normal oil consumption can generally reach 1000 kilometers liters, if the standard is exceeded, there is a situation of burning oil.

Precautionary measures for burning engine oil:

1. Use high-quality engine oil

Engine oil is very easy to corrode and age in a long-term high temperature state, resulting in the oil film becoming thinner, and it is easier to escape to the combustion chamber to participate in combustion, so the use of high-quality engine oil can greatly delay this phenomenon.

2. Pay attention to the cleanliness of the fuel circuit

Fuel in the combustion process is indispensable to produce carbon deposits, and carbon deposits are the root cause of some car failures, such as the aging of valve seals, piston wall clearance, etc., all have a direct or indirect relationship with the formation of carbon deposits, considering the relationship between domestic oil products, it is necessary to use high-quality engine oil and (PNF) fuel additives to achieve, which is also the key to achieve no dismantling and repair to solve the problem of burning engine oil.

When you go to the auto repair shop to check, pay attention to whether the worker has played a small action to add oil to the fuel tank!

If there is no above situation, you should be a hot car when you drive to the auto repair shop, so the reason for the aging of the valve oil seal is ruled out, most likely because the piston ring and the cylinder block are not tightly combined, and the piston ring needs to be replaced! You have to turn on the engine to replace it.

Are you sure that there is blue smoke when you say it? The blue smoke is not burning the engine oil, but the combustion is incomplete, and the ignition time is incorrect. This phenomenon occurs when the mixture is too thick. Accompanied by a lack of motivation.

The obvious characteristics of burning engine oil are black smoke and soot from the exhaust pipe, and carbon accumulation from the spark plug. The oil is reduced too quickly.

The main reasons for burning engine oil are valve oil seals, serious wear of the duct, excessive clearance between the piston and the cylinder, and the loss of tension of the piston ring at high temperature and being stuck in the ring groove by carbon deposits.

Check the spark plug for severe tar and carbon build-up, and if so, need to be repaired.

I'll take a look, if the car inspection is not very serious at that time, it is not easy to see whether the oil is burned in the hot car, and it is obvious when the car is cold (valve seal), but the piston ring can be seen at any time (at the time of departure), Second, it must be overhauled, that is, it is impossible to overhaul only the piston ring, valve seal, but also to change a lot of things, in saying that the second-hand car must be repaired well. Thirdly, there is the engine.

It is recommended to go to the 4S shop to overhaul it, after all, they specialize in repairing a class of cars, which is more professional.

Now if you don't want to burn the engine oil, you have to change the valve oil seals and piston rings, which is an overhaul.

Burning engine oil means that the engine oil enters the engine combustion chamber and participates in combustion together with the mixture. Burning oil in the car will damage the vehicle's oxygen sensor too quickly, resulting in increased carbon deposition in the combustion chamber, resulting in unstable idling, weak acceleration, increased fuel consumption, and excessive exhaust emissions. In severe cases, the engine can be damaged beyond repair or even scrapped.

The main reason for burning engine oil.

1.It is the problem with the fittings, the wastegas valve, the valve seal, the cylinder pulling the cylinder, and the cylinder pressure is insufficient.

2.It is a long-term unclean oil circuit, the antifreeze is not replaced in time, the oil service life is too long, the piston ring is stuck, and the more common situation is that the piston ring is stuck.

Causes of piston ring seizure.

Stagnation starts from the oil circuit, the oil bears the temperature at 110 degrees, and the high temperature caused by the long-term unclean oil circuit makes the oil at a temperature of 120 degrees or higher for a long time, so that the oil will fail in advance, the small hole of the oil ring is very small, and the oil inside will be dried and scabbed for a long time, and a cylinder stuck is a liter of oil for 5000 kilometers, at this time, the working conditions of other cylinders will also begin to be bad, and soon the 4 cylinders are stuck, and it will become a liter of oil for 1000 kilometers or even hundreds of kilometers. Therefore, in order to solve the problem, we must start from the root oil circuit, which is the way to remove the root.

Resolution. There are two ways to solve the problem of burning engine oil, one is overhaul, and the second is PNF repair agent. In the case of overhaul, the cost is very high, the vehicle depreciates quickly, and the later run-in is also very troublesome.

First of all, you need to find out the reason why you are burning engine oil.

1. The piston ring sealing effect is not good, if the car is driven to a normal temperature, but there is still blue smoke from the exhaust pipe, which means that the piston ring seal is abnormal. Once the piston ring sealing effect is poor, it is easy to cause oil burning.

2. The valve oil seal is aging, and when the valve oil seal is aging, it cannot play a better sealing effect. At this time, the oil will directly enter the combustion chamber from the valve to fully burn, and eventually cause the oil to burn.

3. If the oil is not used, when the oil enters the cylinder, the gas impurities cannot obtain a better purification effect. As a result, a lot of dust particles will enter the cylinder, which will accelerate the wear rate of the cylinder and cause the oil to burn.

4. The engine is not maintained in time, which causes the oil to be too dirty, especially in the oil, which will lead to the acceleration of the wear of the engine cylinder, which will cause the car to burn oil.

Automobile oil burning refers to the phenomenon of oil burning due to the friction and wear of various parts inside the engine and the high temperature inside the engine during the operation of the automobile engine, resulting in the loss of engine oil. There are several possible causes of oil burnout:

First, the oil is not changed in time. During the operation of the automobile engine, the oil will deteriorate with the increase in temperature and lose lubricity, which will lead to the aggravation of friction and wear of the internal parts of the engine, which will lead to the loss of oil, which will lead to the burning of the oil.

The second is that the internal temperature of the car engine is too high. If the internal temperature of the car engine is too high, it will cause the temperature of the oil to be too high, which will cause the oil to lose its lubricity, which will lead to the aggravation of friction and wear of the internal parts of the engine, which will lead to the loss of the oil, which will lead to the burning of the oil.

Third, there are impurities inside the car engine. There are impurities inside the engine of the car, which can cause the oil to be contaminated, which will cause the oil to lose its lubricity, which will lead to increased friction and wear of the internal parts of the engine, which will lead to the loss of oil, which will lead to the burning of the oil.

Fourth, the internal parts of the engine are damaged. Damage to the internal parts of the car engine will cause the oil to lose its lubricity, which will lead to the aggravation of friction and wear of the internal parts of the engine, which will lead to the loss of oil, which will lead to the burning of the oil.

Let's first popularize what is burning engine oil. Burning engine oil means that the oil enters the combustion chamber of the engine and burns with the fuel. When the car starts to burn oil, the car will have an increase in carbon deposits and unstable idling.

Weak acceleration. Evidence such as increased fuel consumption and excessive exhaust gas will seriously damage the engine and reduce the service life of the engine.

There are many reasons for burning engine oil, mainly including engine carbon deposits are not cleaned in time, oil filter blockage, excessive oil addition, aging of car front and rear crankshaft oil seals, throttle blockage, air filter blockage, etc.

However, the main reason for burning engine oil in the car is that the oil-oil separator of the car is damaged, resulting in the engine when the engine is working, the fuel and the oil cannot be separated, so the oil enters the engine cylinder for combustion.

The cost of replacing the oil and gas separator is relatively low, and the oil and gas separator imported from Germany is between 300 yuan and 400 yuan, while the oil and gas separator made in China is between 200 yuan and 300 yuan. When the car is replaced with a new oil-air separator, the symptoms of burning engine oil in the car will be reduced, and the engine can work better.

In fact, it is inevitable that the engine of the car will burn the oil, and if the degree of burning the engine oil is relatively low, it can be left untreated. If the burning of engine oil is more serious, then you must go to the repair shop or 4S shop for maintenance in time to prevent the normal use of the car from being affected.

The vehicle stops and goes, the vehicle often ignition, stalling, the temperature of the piston does not come up, and the temperature of the piston does not come up, which is equivalent to a small piston in a large cylinder, so the phenomenon of burning engine oil is quite common.

Avoiding engine oil burning is generally a good and suitable lubricant and replacing it regularly. However, it should be noted that the design concept of the engine is different in each country, so the cost of repair and the effect of repair vary greatly depending on the model in different countries. There is universal and practical advice, which is to use the oil well and change it regularly.

If the engine oil has been burned, then the engine can be repaired or engine repair agent can be used. Recommend a few brands, the United States Red Line, the United Kingdom BP, the United States 3M, the Canadian All-Insman, the German BASF Happy Run, these are the world's top brands.

Whenever possible, a less viscous oil should be used to keep the oil path clear. For example, in the high temperature season or under the condition of severe engine wear, the selection of high viscosity oil is conducive to the formation of oil film and reduces engine wear.

1.Fully synthetic engine oil: Fully synthetic engine oil has better high and low temperature performance, longer oil change interval and is suitable for more severe car conditions, suitable for luxury high-performance vehicles, and is replaced at about 10,000-12,000 kilometers.

2.Semi-synthetic engine oil: The replacement cycle of semi-synthetic engine oil is generally about 8000-10000 kilometers, and the performance is moderate.

3.Mineral oil: This type of oil generally needs to be replaced after about 5000 kilometers.

Try to choose multi-grade oil, multi-grade oil has a better protection effect on the engine due to saving, long life and high efficiency. Based on the characteristics of multi-grade oil, premature blackening and oil pressure may be smaller than that of ordinary oil during use, which is normal.

"Burning oil" means that the oil enters the combustion chamber of the engine and participates in the combustion along with the gas mixture. The phenomenon of "burning oil" in the vehicle will damage the vehicle oxygen sensor too quickly, resulting in an increase in carbon deposition in the combustion chamber, unstable idling, weak acceleration, rising fuel consumption, excessive exhaust emissions and other adverse consequences. In the traffic conditions of frequent starts and stops, many car owners report that their cars "burn engine oil", so it is necessary to understand the hazards, identification and avoidance methods of burning engine oil.

1. Slight burning: fuel consumption, insufficient power, easy to produce carbon deposits, after carbon deposits, it will be difficult to get on the car, and the engine will shake.

2. Severe burning: The oil consumption is very large, and the engine is very worn. When the oil burns out, the engine will be overhauled!

3. Identification and inspection: the concentration of blue smoke. Pull out the oil ruler often to see how fast the oil is consumed.

4. Suggestion: If you plan to open it, deal with it as soon as possible, which is the most cost-effective and worry-free. If you don't plan to open it, make another plan as soon as possible, it's very serious, it's not easy to sell, and the price is low.
