Is the blackening of the Audi A4L car exhaust pipe a sign of burning engine oil?

1. The processing technology of the engine cylinder of Audi car, the engine cylinder wall is shown as a mesh under the microscope, and 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 Audi 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 and tear caused by the piston ring running up and down on the cylinder wall, so the Volkswagen car has traveled 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, Audi car manufacturers burn engine 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

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.

3. With the help of external forces

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 solving the problem of burning engine oil without dismantling and repair.

Most of the cars on the market now burn engine oil, and most of them are French cars, German cars, and BMW cars.

The main reason for burning engine oil

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

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 have to find out the reason for your burning oil, and you can refer to it if you have repaired it with a repair agent before.

If it is relatively wet and there is sludge, the blue smoke must be burning engine oil. If only blackening is normal.

The reason why it is blackened is because the carbon deposits in the oil circuit of gasoline are not clean for a long time. Gasoline contains minerals, which will produce carbon deposits as long as it is burned;

Cause cylinder pressure to decline; If it is deposited in the engine, it will cause poor lubrication, increased wear, increased fuel consumption, decreased power, and cause oil burning. In this case, it is necessary to clean the oil circuit with Siyoupu;

caused by the exhaust pipe of the vehicle that burns the engine oil is blue smoke; Black smoke from the fuel throttle is generally caused by insufficient combustion of the engine, which may be caused by the failure of the engine electronic control system (the intake pressure sensor is damaged or if the hand start, the mass signal is wrong, and the ignition and fuel injection timing is incorrect), the ignition system is damaged (the ignition energy is low), the cylinder pressure is insufficient, etc. Further maintenance is required to determine the cause of the failure.

Generally, the stool stall that emits black smoke is caused by the mixing of jujube sales and excessive qi. Doesn't it have a direct relationship with burning engine oil? At this time, you can also read the data stream and take a look at the fighting family.

Volkswagen EA888 low-power version canceled double injection, is it a disguised reduction, in fact, high and low power are two different engines, although they are called EA888, the high-power version has more twin scrolls and double injections than the low-power version, and the variable valve lift of the high-power version uses the Otto cycle on the exhaust side, the valve lift of the low-power version is actually on the intake side, and the Miller cycle is added, the high-power spike version is biased towards performance, and the modification of the He Yun Qianchai source force is huge, and the low-power version is energy-saving, high thermal efficiency so fuel saving. So how to choose or depends on the owner's car orientation, if you like modification, hope to have more horsepower, then start with the high-power version, if it is home, there is no speed demand then the low-power version is definitely enough.

It can also be caused by insufficient combustion. There are many reasons for this, and it is recommended to go to the repair shop to check it out.

1 all hello, black smoke is not burning oil, but insufficient combustion, it is recommended that you go to the repair shop with a diagnostic instrument to detect it, if not repaired will be very oil-intensive, blue smoke is the performance of burning engine oil, I hope it can help you, I wish you a happy car [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, black smoke is not a phenomenon of burning engine oil, this is too much fuel injection, it is recommended to check the throttle, fuel injector, and itch sensor, these will affect you, I hope to help you [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, black smoke is not good for burning, and there is a basket of smoke for burning engine oil. Generally, the black smoke is due to the spark plug ignition energy is not enough Fuel injector leakage Intake pressure sensor , oxygen sensor, I hope my answer can help you [Car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello dear, burning engine oil is blue smoke, and black smoke is too thick of the mixture [car question, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Under normal circumstances, it is not to burn the engine oil, if the oil is burning the smoke, it is recommended to change the air filter element and give it a try.

The new Audi A4L burns oil mainly in the direct injection turbocharged models.

Therefore, the correct run-in method of new car is still essential. If you throttle, fully load or drive at high speed during the run-in period, it will also have a certain impact on the excessive consumption of the engine and oil. Since the consumption of engine oil in the case of a cold car is also higher than that of a hot car, it is necessary to allow about half a minute of residual heat time after the engine is ignited, especially in the overnight car.

In addition, it is necessary to learn to warm up during driving and not to drive vigorously at the beginning of the drive after the vehicle is started, which will also reduce oil consumption as much as possible.

The engine of the Audi car is relatively easy to burn the engine oil, which is a design loophole of the designer, and many German cars have this problem, and you are not alone.

First of all, you need to confirm the reason for burning engine oil, and the main reasons for burning engine oil are two aspects.

First, there is a problem with the accessories, the exhaust valve, the valve seal, the cylinder stove is good, and the cylinder pressure is insufficient.

The second is that the oil circuit is not cleaned for a long time, the antifreeze is not replaced in time, the oil service life is too long, and the piston ring is stuck, and the more common situation is that the piston ring is stuck.

Causes of piston ring seizure

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.

The solution to burning engine oil in Audi cars.

First of all, you need to check the accessories. If it is a damage to the accessory, the accessory needs to be replaced. Check if there is a serious problem with the cylinder. If there is a serious situation of pulling the cylinder, you can directly choose to overhaul the engine and replace the middle cylinder. If there is no pull cylinder or slight pull cylinder, you can do not rush to overhaul it first.

Burning engine oil is not a terminal disease, there is a way to solve it, and it is not necessary to overhaul the engine with hidden lead. Overhaul is self-evident on engine damage, and many car owners will still burn engine oil after overhaul. At present, the solution to the problem of burning engine oil has matured, so there is one more option for the treatment of burning engine oil!

As long as you use the general burning oil repair agent for 4 times in a row, you can clean the carbon deposits on the top of the piston and release the piston ring.

The solution to burning engine oil in Audi link.

Asking for Advice Two situations: 1One is to burn the engine oil directly; That is, there is a problem in the engine cylinder (cylinder wall strain, or the piston oil ring, air ring and cylinder wall gap is too large), causing too much crankcase oil to flow into the cylinder, combustion chamber mixed burning, exhaust pipe blue smoke, power drop and return and engine overheating; 2.

the other is indirect burning of engine oil; That is, the engine crankcase ventilation and oil-oil separation system function failure, oil and gas separation is not complete, resulting in the separated gas containing excess oil, with the intake air into the intake manifold and combustion chamber mixed firing, commonly known as the engine intake system oil channeling phenomenon. In the process of engine work, the engine oil enters the engine cylinder and burns together with the gasoline, which is what we often call "burning engine oil"!It is generally caused by several reasons such as mold hand hunger

1. The gap between the piston and the piston ring becomes larger, the piston ring is too worn, and the cylinder liner is overworn, which causes "pump oil"; 2. The gap between the valve guide sleeve and the valve stem is too large and leaks; 3. The cylinder gasket oil circuit hole is connected with the cylinder, referred to as "oil and gas mixing". It usually appears as blue smoke. Exhaust pipe organic oil, high temperature and other appearances.

It is recommended that you go for repairs immediately. The function of the oil-gas separator is faulty, or the piston ring interval is too large, and the engine oil will be burned. The poor sealing of the cylinder is the main cause of oil burning.

The main reason is that the matching gap between the piston 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 oil. Choose good quality engine oil as much as possible, old vehicles can appropriately choose slightly more viscous engine oil to increase the tightness between the piston and cylinder wall, use mineral engine oil for a long time, and change to fully synthetic engine oil is also prone to poor sealing. Checking the oil scale frequently and changing the oil and oil filter regularly can effectively avoid burning the oil.
