Why do Volkswagen cars often burn engine oil

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.

The main oil burning is the cylinder block, the contact surface in the cylinder ——— the cylinder wall and the piston, due to various reasons caused by the increase in the matching gap and the poor sealing, resulting in the oil jumping up to the combustion chamber and burning the engine oil, the specific reasons are as follows: First, the coordination of the contact surface. Different models have different processing accuracy.

The precision of economy cars is slightly lower, and the clearance of some cars is slightly greater than that of high-end models, so the fully synthetic engine oil used in some economy cars is not very suitable, and the oil consumption will increase. In addition, the assembly errors of the individual components are inconsistent, which leads to differences in the individuality of the vehicles. Second, the piston ring, which plays a sealing role.

The quality of the piston rings is different, the elastic strength is also different, and the high-frequency reciprocating movement in the cylinder is highlighted, and the sealing effect is naturally different. Third, with the extension of the use time, the incomplete combustion products ——— carbon or manganese deposits, so that the piston ring adhesive loses elasticity, and the flat shaft friction appears, so that the piston ring or cylinder wall wears, resulting in the burning of engine oil. Fourth, the cylinder or cylinder wall is seriously worn, resulting in too large a gap between the two, and excess oil enters the combustion chamber.

Fifth, the design of engine materials is different, and the requirements for oil film are also different. In addition, the oil burned by the quality of maintenance should not be underestimated. For example, whether the bolts are tightened, whether the piston rings are installed correctly, whether the damaged oil seals are replaced, etc.

On the other hand, the oil from the cylinder head is mainly due to the aging or damage of the valve oil seal, the valve guide is eccentric and the clearance increases, resulting in the oil entering the combustion chamber and becoming another major oil burner. European cars and American cars burn engine oil, as well as those with T, which are relatively normal.

Burning engine oil is not a big deal, normal,

Burn the engine oil to see what is causing it, although it is not a serious problem, or to prevent it, to prevent the cylinder, go to the repair shop to check it.

Generally, it is the reason for the oil seal of the door of the filial piety, the large piston clearance, the driving habits, the amount of oil and oil, etc., you can check according to these directions.

Volkswagen's engine oil is mainly the pot of the oil-gas separator. The second-generation EA888 uses a cyclone separator, and due to design defects, the pressure spool spring under the cyclone is too large or the spool is stuck, which causes the pressure in the engine crankcase to slowly increase. The abnormally increased pressure directly squeezes the oil out of the sealing ring, forcing the engine to seal the oil leakage in many places, and at the same time, it will also cause the PCV valve to directly open and discharge high-pressure exhaust gases.

The PCV valve body of EA888 is located just above the camshaft, and the oil splashed by the camshaft can directly enter through the PCV valve and be sucked into the combustion chamber through the engine intake system. That's the real reason why the second-generation EA888 engine burns oil.

Of course, there are also voices saying that the second-generation EA888 is due to the special mesh texture of the engine cylinder wall (grinding process), which causes the piston ring to be unclean, resulting in the phenomenon of burning oil. But I don't think that argument is tenable at all. Because the engine with the cylinder wall using the grinding process is very widely used, and other engines using this process do not burn oil, so it is not convincing to use the grinding process to explain the oil burning of Volkswagen.

Volkswagen's hair is absolutely motivated to burn engine oil because the design of the oil-air separator is unreasonable, and the gap between the piston ring and the cylinder wall is too large. If the fuel consumption is within the normal range, there is no need to care. If the oil consumption is higher than the normal range, it needs to be repaired.

Engine oil is known as the blood of the engine. If there is no oil in the engine, the engine will not function properly.

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

When the engine is running, the oil forms an oil film on the surface of the engine components.

In this way, friction caused by direct contact between the various components in the engine is prevented.

If the components in the engine are in direct contact with each other, friction can increase engine wear.

The performance of the engine oil will be reduced after a long period of use, so it is necessary to change the engine oil regularly.

If the oil is not changed in time, engine wear can be exacerbated.

Replace the oil filter with each oil change.

The oil filter element is used to filter the oil. If there is no oil filter, the oil will be 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, you must choose a big brand, and you must buy it from regular channels.

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 will form a layer of oil 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. Boom.

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.

If there is no oil filter, the oil will 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.
