Yedi 1 4t manual polar version burns engine oil

Hello, Yedi manual polar version of the new car will not burn oil unless the engine has quality problems, normal operation, regular maintenance, the general burning of engine oil will occur in about 200,000 kilometers, I hope to help you, if you are not sure, please log in to the Baichebao Q&A to find me.

Causes of burning engine oil and how to prevent it.

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the following reasons will aggravate the oil consumption and cause the burning of engine oil, so that the vehicle appears:

1. Carbon deposition occurs in the combustion chamber, which makes the gas ring of the piston ring stuck, and the sealing is poor.

2. Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

3. Wear occurs between the piston and the cylinder wall.

4. The valve seal is corroded and aging, and the sealing performance fails.

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem.

Burning engine oil means that the engine oil enters the combustion chamber of the engine and participates in the combustion along with the mixture. The phenomenon of "burning engine oil" in the vehicle will damage the vehicle's oxygen sensor too quickly, resulting in an increase in carbon deposition in the combustion chamber, unstable idling, weak acceleration, increased fuel consumption, and excessive exhaust emissions.

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., are directly or indirectly related to 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 point to achieve no dismantling and repair to solve the problem of burning engine oil.

Volkswagen Qi Zai's supercharged cars generally burn engine oil.

But it's not a big problem, this wild emperor is Skoda.

I don't know if the current use of Gao Juwang is the Volkswagen's god-shielding technology or Skoda's own technology, it should not be a big problem, not as serious as imagined.

First, the main reason for burning 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 can lead to poor engine lubrication, increased wear of piston rings and cylinder walls, and reduced sealing performance, resulting in 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 draft valve (PCV) or crankcase vent blockage can cause excessive pressure in the crankcase to cause the oil to enter the cylinder with the crankcase gas and participate in combustion.

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 turbocharger. 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.

Second, the method of preventing the burning of engine oil.

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.

The quality index refers to the grade above SL as much as possible, and the viscosity index should be strictly in accordance with the provisions of the viscosity index in the automobile manual, and cannot be too low or too high.

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.

There is no news about this car to burn the engine oil now, I hope it can help you, I wish you a safe ride.

For the time being, there is still no problem of burning engine oil, and I hope it can help you.

This car doesn't burn oil.

Hello, this car does not burn engine oil, I hope it can help you!

The turbocharged engines carried by Yedi, including EA211 engine and EA888 engine, are engines with large oil consumption, and it is a matter of time before the maintenance oil is not standardized. First of all, for turbocharged vehicles, it must be used with fully synthetic engine oil. The moment the turbine starts working, the engine torque increases exponentially, and according to the principle of turbocharging technology, the oil film covering the engine crankshaft is subjected to several times higher shear forces than before.

If the oil film is broken, it will increase the wear of the engine and reduce the overall life of the engine, because the base oil molecules of the fully synthetic engine oil are arranged neatly and have high oil film strength, so it can meet the requirements of the turbine engine for high temperature and high rotation of the oil film.

Secondly, in view of the problem of burning engine oil, EA211 engine, the biggest feature is direct injection in the cylinder, gasoline atomization is short, easy to produce carbon particles, and the engine temperature is high, the main reason is that Volkswagen has increased the turbine speed, high temperature and carbon residue will accelerate the deterioration of engine oil, so there will be organic oil consumption too fast, in view of this situation, the standard for choosing engine oil is, first, to choose 5w40 viscosity of fully synthetic engine oil. Second, choose an oil with a higher total base number to neutralize the acid group in the gasoline and slow down the deterioration of the oil. Thirdly, it is necessary to choose the engine oil of the ACEA (European Automobile Manufacturers Association) standard, the reason is simple, there are many oil standards in the ACEA, which were proposed by the "Volkswagen Group", one of the members of the association.

Fourth, it is necessary to choose an oil with a higher shear viscosity than HTHS at high temperature, so as to ensure the thickness and strength of the oil film under high temperature and high shear force

The A3 B4 standard requires the > of HTS, which is also proposed by the public. In view of this situation, it is recommended that you use Motorgold fully synthetic 5W40 engine oil imported from Germany, which has a formula to alleviate oil burning, which can effectively increase the tightness of the German engine mesh oil storage grid cylinder and prevent the oil from being brought to the combustion chamber when the piston is running. It has a high-temperature flash point of more than 220 degrees, which reflects strong anti-high-temperature evaporation and high-temperature oxidation resistance under intense working conditions of the engine, effectively alleviates oil burning and prolongs oil change mileage.

HTHS High Temperature High Shear Viscosity (ACEA:

The A3 and B4 standard requirements should not be lower than to ensure that the friction pair has a super adhesion ability, so that the engine is protected by a high-strength oil film, reduce wear, strengthen the seal, and reduce oil consumption. Hope to adopt.
