Why do Volkswagen cars burn engine oil so much

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 will be oil loss every 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

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 cylinder wall clearance, etc., all of which are directly or indirectly related to the formation of carbon deposits, so keeping the fuel circuit clean is of great help to prevent burning engine oil, of course, this needs to be done with the help of high-quality PNF fuel additives.

As the turbocharged engine runs for a long time, the water vapor generated by the high-temperature oxidation of the oil is sucked into the combustion chamber through the crankcase ventilation valve. Domestic traffic congestion, and many traffic lights, vehicles need to stop-and-go, so that the engine is often in the idle state, so that the residual oil in the cylinder mesh is more, so burning engine oil will be more common.

Due to the fact that Volkswagen's engine gas is blind and the cylinder wall stores the engine oil in the form of a mesh, the residual oil in the mesh will be burned out due to the increase in temperature during piston operation. When this kind of cylinder is used in Europe, the speed of the vehicle is usually faster because of the oil in Europe and the good road conditions. When the engine is running at high speed, the oil remaining in the mesh will be reduced, so the oil burned is very small.

Why does Volkswagen burn engine oil so much

Reasons for burning engine oil:

1.Do not do effective cleaning oil circuit for a long time, 2The antifreeze is not replaced in time, 3The oil life cycle is too long.

4.Long-term short-distance driving. The car that burns engine oil must occupy one or all four points. Please be seated.

Find the cause of burning the oil

One is the accessories, the other is that the oil circuit is not clean, carbon is deposited, and the piston ring is stuck. It is recommended that you confirm the cause of burning engine oil first, so that you can solve it in a targeted manner. Check the fittings first, mainly the valve chamber cover and the exhaust valve.

They are one. When it comes to inspection, just check it together. Then, measure the pressure of the gas code orange cylinder to see if there is piston ring matching and cylinder pulling.

If there is no problem, the fault of the accessories can be basically eliminated, which is the burning oil caused by the stuck piston ring.

Jamming starts with the oil circuit. The temperature of the engine oil is 110 degrees, and the high temperature caused by the long-term unclean oil circuit makes the oil stay at a temperature of 120 degrees or even higher for a long time, so that the oil will be exhausted in advance, and the holes in the oil ring will be very small. The oil inside will dry up after a long time.

One cylinder card 5000 kilometers a liter of oil. At this time, the operating conditions of other cylinders will also start to deteriorate. Soon, all four cylinders will be stuck, and to solve the problem, it is necessary to start from the root oil circuit.

Solutions for burning engine oil

Overhaul

First, overhaul, maintenance of multi-person operation technology is not unified and assembly is not good, the hot and cold value of the engine assembled at room temperature is not enough, overhaul 1-40,000, vehicle depreciation 3-60,000. The disadvantages of overhaul: do not turn on the engine as a last resort, after opening, there are traces of disassembly, the car instantly depreciates a lot, and the result of assembly is unknown.

In the process of dismantling and assembly, the humidity of the air, constant temperature, low temperature are unable to meet the environment of the dust-free workshop operation, there are many people in the plugging and assembly, the technology is not the same, and the assembly can not ensure the stability of a machine because of the screwing and other links, often the later car volume is unable to consume fuel, shaking and other phenomena are found. Don't disassemble the engine without serious cylinder pulling. After the overhaul, 2000 kilometers to change a fully synthetic engine oil to two times in a row, plus to find a posture mold fluid good road conditions to run in separately, 3000-5000 kilometers to complete the run-in, the cost of oil + gasoline is very high, the cost of ordinary car overhaul run-in is 2000 yuan.

And once you call the police, you can call a tow truck immediately, which is more troublesome.

Non-destructive repair

The second is that 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. It has nothing to do with the valve seal, this car will not be broken for 16w km or 20w km. The problem of burning oil caused by piston ring stagnation is a phenomenon that occurs in most oil-burning vehicles, you can take a look at this Magotan owner method, he uses PNF repair agent, you can clean the carbon deposits on the top of the piston and release the piston ring.

At present, Volkswagen's engine oil is mainly for EA111 and EA888 engines.

The main reason is that the engine with the TSI kit burns oil, and the official explanation is normal consumption.

The principle of operation is that the two engines are covered with tapered holes in the cylinder wall, which form a net.

Its purpose is mainly to help form an oil film and reduce wear while the piston is working.

However, the oil in the holes of the combustion chamber will be consumed, which is currently commonly known as the phenomenon of burning engine oil.

This design does consume some of the oil, but it will significantly extend the life of the powertrain.

Hello! Because of the turbocharger, there is also the problem of cylinder design! If you don't understand, you can ask, I wish you a happy life! [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Specifically, it is divided into models.

Volkswagen has some.

In the dual-supercharged model.

will form an oil film on the cylinder wall.

The part in the combustion chamber will be burned out.

That's what it is. Change engine life with oil, hope mine can help you.

the formation process of burning engine oil in automobiles; Step 1. The long-term unclean oil circuit of the car leads to the increase of gum impurities and moisture in the oil circuit, and the carbon deposit exceeds the standard due to poor combustion.

Step 2. Excessive carbon deposition leads to a significant decrease in engine condition and greater carbon deposition, and eventually piston ring stagnation and related parts aging.

Step 3. Slight oil burns begin to appear.

Step 4. Because burning engine oil produces greater carbon deposits.

Step 6. The trunk went from having one liter of oil ready to being ready for two or three liters of oil at any time.

Step 7. The overhaul was too expensive, and it was delayed, until in the end, the engine was overhauled with a burst cylinder.

Volkswagen's engine oil burns because of the poor design of the oil-air separator and also because of the excessive clearance between the piston rings and the cylinder wall. If the oil consumption is within the normal range, then there is no need to care. If the oil consumption is beyond the normal range, it is time for repairs.

Engine oil is called the blood of the engine, and if there is no oil in the engine, the engine cannot function properly.

Engine oil not only plays a lubricating role in the engine, but also plays a role in cleaning, sealing, buffering, rust prevention, and heat dissipation.

When the engine is running, the oil forms a film on the surface of various parts of the engine.

This prevents friction from direct contact between the various components within the engine.

If the various parts within the engine come into direct contact and cause friction, it will exacerbate the wear and tear of the engine.

The performance of the engine oil will be reduced after a long period of use, so the engine oil needs to be changed regularly.

If you don't change the oil on time, it will exacerbate the wear and tear of your engine.

Every time you change the oil, change the oil filter as well.

The oil filter element is used to filter the engine oil, if there is no oil filter element, the oil will also be very dirty after a period of use, which will also affect the lubrication and heat dissipation of the engine.

When buying engine oil and oil filter cartridges, be sure to choose the best products from big brands, and be sure to buy them from regular channels.

Online information should pay attention to the screening of Volkswagen car sales are very high, if there is a serious quality problem, it must be. It won't go on for a long time, so to speak. Volkswagen cars rarely burn engine oil.

Burning engine oil is generally in the following aspects. First. There is a problem with the oil itself. Second. There is a leak inside the engine. This causes the oil to escape into the combustion chamber. For example, the piston rings are worn abnormally. The third type of turbocharged burner oil.

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 finally 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, 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.

At present, the effective method of hitting the stove is to use the oil burning oil repair agent of the original solution of the company to clean the oil circuit and the cylinder, and release the carbon sludge stuck in the piston ring by penetrating into the piston ring. For most of the vehicles where the piston ring does not have a counterpart, the stagnation can be completed as long as it is repaired in this way, and the oil wiping function can be restored to improve the phenomenon of burning oil.

Volkswagen burns engine oil because there is a problem with the engine parts, which causes the oil to enter the combustion chamber and burn out. Basically, it is because the oil-air separator is not completely separated, the oil seal is aging and damaged, or the piston ring is seriously worn. The complete solution is to overhaul the engine and replace the defective parts.

But the maintenance cost is not low, and the maintenance time is long. As a last resort, it's best not to do this. In addition, if the engine oil used is a base oil of four PAOs, even if the engine oil is burned, there will be no carbon deposits and impurities, and it will have little impact on the engine power.

At the same time, it can lubricate and protect the engine, and the power will not be affected.

Why does Volkswagen burn engine oil

It's not just Volkswagen that burns engine oil, but other models also burn engine oil, which is already a normal thing

To solve the problem of burning engine oil, first know the reason for burning engine oil.

1.First, check the reason for burning the oil-related accessories and eliminate the problems of the relevant accessories.

2.Through the first step to eliminate the relevant accessories and ask the closed front problem, it is determined that the piston ring is stuck and causes the oil burning problem.

Determining the piston ring is to be deduced in reverse to determine the reason for the piston ring, so it is very simple to check the external accessories, and the second state can be determined to be the piston ring, so as not to take a detour.

How often does burning oil occur

There is no warning of burning engine oil, and it is said that it will burn, and the illness will come like a mountain. Moreover, the new car has not burned engine oil for tens of thousands of kilometers, and once it starts to burn engine oil, it will become very serious in half a year and half a year. I don't think you want to go through such a process, but it has happened that the engine has been revitalized by oil, and it has become a serious oil burn, so it is recommended to check it first, and don't rush to deal with the engine problem blindly.

Burning engine oil will lead to juddering, weakness, high fuel consumption and other possible phenomena, these are caused by burning engine oil, don't be in a hurry to deal with small phenomena, first deal with the problem of burning engine oil.

Workaround:

Don't worry about burning engine oil, prescribe the right medicine, as long as the carbon deposition problem of the piston snap ring is solved, there is no need for overhaul, and the oil burning problem can be directly repaired with PNF repair agent.
