Audi A4L burns engine oil causes and solutions

Reasons why the Audi A4L burns engine oil:

Under what circumstances does a car burn engine oil?

1. Use engine oil with poor quality or viscosity grade that does not meet the requirements. In addition, too low or too high oil viscosity will cause poor engine lubrication, increase the wear of piston rings and cylinder walls, reduce sealing performance, and lead to oil burning.

2. The matching gap between the piston ring and the cylinder wall is too large, the piston ring is improperly installed or the sealing is poor, and the oil on the cylinder wall enters the combustion chamber, causing the phenomenon of burning the engine oil; In addition, poor sealing performance of the valve seal, damage to the crankcase forced ventilation valve or crankcase vent blockage will cause the oil to enter the cylinder with the crankcase gas to participate in combustion. If your car has not been damaged, which will happen after 7 years, Che Yian recommends checking the engine condition of your vehicle regularly.

3. Burning engine oil caused by excessive oil filling. When the oil is filled above the center line, the part of the engine lubrication process that passes through splash lubrication will be too much into the combustion chamber due to the high oil pressure.

4. Oil leakage from the turbocharger (model with T). The turbocharger is mounted at the front of the exhaust pipe and operates at a very high temperature, and the turbine and pump wheels can reach 120,000 revolutions per minute when the engine is running at full load. The turbine shaft has oil-lubricated floating bearings, and the car has one oil passage to the turbocharger.

Oil leaks from pipes or bearings can allow oil to seep from the turbocharger into the exhaust pipe. When the exhaust pipe temperature is high, the oil is baked and discharged into blue smoke.

5. There is leakage in the valve oil seal, which means that the oil leaks into the combustion chamber through the valve oil seal.

1. Use engine oil that meets the technical requirements of the vehicle. Many car owners never read the vehicle manual, and they don't know what quality and viscosity grade oil their vehicles use for a few years, and there is a lot of arbitrariness in the use of engine oil. When using engine oil, one is to pay attention to the quality index, and the other is to pay attention to the viscosity index.

2. Avoid frequent rapid acceleration and long-term ultra-high-speed driving. When the engine rotates at ultra-high speed, it is easy to break the lubricating oil film, resulting in poor lubrication and dry grinding of the rotating parts, and when it becomes a regular operation, it will make the engine wear abnormally and burn the oil, therefore, maintaining economic speed is one of the best ways to prevent the phenomenon of burning oil.

3. The oil must meet the specifications when filling. When the oil filling volume exceeds the center line, the repairman should be asked to pump out the excess oil, in addition, the oil volume should be observed before the next day.

4. If you find that the engine oil is burned, go to the maintenance station for inspection as soon as possible. If it is due to engine failure (such as poor piston ring sealing, valve oil seal leakage, cylinder gasket leakage, etc.), you should go to the maintenance station as soon as possible to check and repair the fault as soon as possible.

At present, the most advanced method of repairing burned engine oil:

Under the premise of determining that there is no problem with the oil seal exhaust valve and turbine, the direct use of the method of non-destructive repair of the burning oil, do not disassemble the accessories and do not remove the screws, and the repair of the burning oil can be completed while driving, which is the most convenient repair technology at present, and the owner can complete the repair of the burning oil by himself.

A good solution to the problem of burning engine oil in Audi.

The incident of Audi A4L burning engine oil happened, do we really not understand the use of engine oil of big brands, or does the product have its own internal problems? Follow me to find out the causes and solutions of Audi A4L burning engine oil!

Audi A4L burns engine oil.

Cause. 1. New car running-in: Many professional technicians pointed out that many people use inappropriate methods during the run-in period after buying Audi A4L vehicles.

There are many motorists who react to burning engine oil when it happens, and it is within a range of 4,000 kilometers. Therefore, when driving 5,000 kilometers, the merchant will provide the first warranty service, thus solving the problem of burning engine oil in the later stage.

Cause. Second, layered combustion: this situation is mainly related to the engine of the model, because the thickness of the piston is thinner than its conventional one, so it is also very different from the conventional piston when running at high temperatures.

There will also be gaps in the work, so that the oil flows out of the gaps and burns the engine oil. Many riders report that the oil loss of the model is relatively high, which is one of the reasons!

Cause. 3. Dealer behavior: Because there are defects in the process of engine production and design, it may be a little difficult to solve it fundamentally.

If this is the case, it is recommended that the only way to alleviate the rapid consumption of engine oil is to improve the quality of the engine oil.

Audi A4L burns engine oil impact.

Effect. First, it leads to an increase in the fuel consumption of the car, the exhaust gas quality is exceeded, the idle speed during driving is not stable enough, the driving danger is increased, and the economic burden of users increases.

Effect. Second, it leads to the increase of carbon deposits inside the engine, the starting acceleration is weak, the speed is slow, and the power provided cannot be satisfied.

Effect. Third, the life of the sensor in the car becomes shorter, the lubrication capacity of the oil is insufficient, the damage to the engine cannot be repaired, and the cost of maintenance is greatly increased.

Audi A4L burns engine oil to solve.

Resolution. 1. Pay attention to the standardization of the run-in period, do not drive recklessly, and cooperate with the relevant run-in regulations for regular driving.

Resolution. Second, we must develop a good driving habit, if the driving mode after the run-in period must also be standardized, otherwise the incident of burning engine oil will continue to occur.

Resolution. Third, the quality of the engine oil is also very important, do not give up your life because of the cheap. Also pay attention to know what brand and model of engine oil is used in the vehicle from the factory.

Resolution. Fourth, the conscience of the business community is something that we can't do, and I hope that businesses can act with conscience.

Epilogue. Only by doing your duty and norms can you have a life guarantee.

In order to protect the engine and prolong the life of the engine, German cars are designed to reduce the frictional resistance between the piston ring and the cylinder wall, and an oil film will be formed in the cylinder wall, and part of the oil film will be burned off with the gas burned at high temperature, so the oil loss is more than the same period last year.

1. Volkswagen's processing technology for engine cylinders, the engine cylinder wall is shown as a mesh shape under the microscope, each small mesh is a "small oil depot" for storing oil, and the piston has better lubrication performance than the flat cylinder wall when running up and down in the cylinder, which also minimizes the wear between the piston ring and the cylinder wall.

2. The toughness of the piston ring of the Volkswagen car is better, and the degree of tension is weaker than that of the Japanese car, simply put, it is strong, but the elasticity is small, and this matching naturally reduces the wear caused by the piston ring running up and down on the cylinder wall, so the Volkswagen car after driving hundreds of thousands of kilometers to measure the wear of the cylinder wall of the engine, which is much smaller than that of other car series, and the engine can still maintain good working condition.

3. The engine is like the heart of the car, the engine burns oil in the final analysis, or the piston ring has a problem, under normal circumstances, there is no oil loss of 1000km, if it exceeds too much, it is possible to burn oil. If there is a problem with the sealing of the piston ring, the oil will follow the movement of the piston and secretly drill into the combustion chamber to participate in the combustion, and then the oil will be burned.

4. In order to prolong the service life of the engine, Volkswagen manufacturers cause engine oil to be burned.

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

Carbon deposition is indispensable in the combustion process, and carbon deposition is the root cause of some automobile failures, such as the aging of valve seals, piston wall clearance, etc., which are directly or indirectly related to the formation of carbon deposition, so keeping the fuel oil circuit clean is of great help to prevent burning engine oil, of course, this needs to be done with the help of high-quality fuel additives.

There is no good way, industry insiders say that Audi burns engine oil maintenance can not solve the problem, don't listen to the flicker of the 4S shop. This is a common problem of German cars, and it is recommended that you keep an oil in your car, and it is best to keep a barrel of oil in your car.

Normal. If it's not serious, keep a bucket in the trunk.

If it's serious, it's going to be repaired.

There are two ways to solve the problem of burning engine oil

Overhaul. PNF restoratives.

Benefits of this one: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 have to find out the reason for your burning oil, oil circuit blockage, carbon deposits, piston ring stagnation can be repaired with repair agent, there are riders who have repaired it with repair agent before, you can refer to it.

Not a major overhaul to solve the problem of burning engine oil.

All kinds of models repair the record of burning engine oil.

If it is determined that the oil is burned by the 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 taken out directly, and the piston ring can be replaced.

1. Valve oil seal: The valve is actually used to prevent oil leakage into the combustion chamber, but with the delay of time, it will more or less wear or aging. If it is serious, it will affect the tightness of the valve, so it is easy to burn the engine oil.

2. The piston gap is too large: when the car is used for a long time, there must be carbon deposits attached to the piston ring, but if it is not cleaned for a long time, it is likely to expand the gap between the piston ring and the cylinder block, resulting in the oil flowing into the combustion chamber, resulting in the burning of engine oil, and in serious cases, it will also lead to the phenomenon of engine bursting.

1. The selection of engine oil should be selected according to the requirements of the engine, and it is not necessary to use too high-grade engine oil on the engine with lower requirements, nor can the lower-grade engine oil be used on the engine with higher requirements.

2. Multi-grade oil should be selected as much as possible, because multi-grade oil has a good protective effect on the engine due to its 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.

3. If the engine is in good condition and the temperature is low in season, the oil with low viscosity should be used as much as possible to make the oil circuit smooth. 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.

Either overhaul the engine, or get a new machine. The cost of both is relatively high.

As for how long it will take for the car to burn engine oil, it is difficult to say, mainly depending on the degree of burning engine oil, the performance of burning engine oil is that blue smoke will come out of the exhaust pipe. If you run 10,000 kilometers and consume 3L of engine oil, it is more serious, at this time you need to overhaul the engine, replace the corresponding seals or components, and clean the engine carbon deposits.

Identify the cause and target treatment; There are many reasons for burning engine oil, such as: turbocharger damage, valve guide wear oil seal aging, piston ring wear, large three-gap gap, piston cylinder sticking cylinder, etc.

See how to solve the after-sales service, 1If the old vehicle burns oil, you can choose to add a relatively high viscosity oil to the engine to increase the sealing between the engine piston and the cylinder wall.

2.The ultimate way to completely solve the problem of burning engine oil is to overhaul the vehicle more thoroughly in order to fundamentally solve the problem.

3.If you notice signs of burning engine oil, check the oil gauge frequently. Regularly replace the oil and oil filter according to the requirements of the product instruction manual, and replace the ** oil filter spare parts.

First of all, burning engine oil will roughly lead to the following 4 points1Burning engine oil will cause damage to the vehicle's oxygen sensor too quickly;

2.Burning engine oil will lead to an increase in fuel consumption, excessive exhaust emissions, and unstable idling, which will increase the hidden dangers of automobiles and increase the economic burden.

3.Burning engine oil will lead to undesirable consequences such as increased carbon deposition in the combustion chamber of the engine, weak acceleration, slow speed, and insufficient power.

4.Long-term oil burning is not solved, resulting in insufficient engine lubrication, causing irreparable damage or even scrapping of the engine, resulting in a significant increase in maintenance costs and even potential accidents. The main reasons for burning engine oil are:

The difference in the coefficient of thermal expansion of the metal at the cylinder interface of the TSI causes the metal to have a slight leakage, which is officially recognized by Audi! But to be honest, the problem of burning engine oil is very common in cars, because models with all-aluminum shells and cast iron cylinders are still relatively common at present, but the amount of Audi slightly exceeds the specified standard!

Why does Audi A4L burn engine oil, what are the consequences of burning engine oil It seems that even if the car is a domestic car, but the sensor is very sensitive, in order to ensure environmental protection requirements, so, when encountering the fault code of exhaust VV, and the kilometers are only tens of thousands of kilometers, first consider cleaning the oil circuit instead of changing accessories. If the oil circuit is dirty, the computer can't detect it, but this will really affect the combustion quality, and finally affect the exhaust quality, so that the fault light will be on. As long as the cleaning agent such as the cleaning agent is used to clean the oil tank, the combustion will improve the impurities of the clean oil circuit, improve the emission effect, and the fault lamp will disappear automatically after a few tanks of oil.
