Under what circumstances does a car burn engine oil?

The main phenomenon of burning engine oil is the exhaust pipe emitting blue smoke, and the oil consumption in the engine is significantly increased. There are two reasons for this: First, natural wear and tear.

With the increase of the mileage of the car, the wear between the piston and the cylinder gradually increases, when the wear increases to a certain extent, the cylinder blow-by will begin, and then the phenomenon of burning engine oil will occur. When the valve oil seal is damaged, it will make the oil burning phenomenon more obvious. 2. Improper maintenance.

1. Maintaining the engine according to the specified mileage will prolong the service life of the engine. On the contrary, even if the mileage is exceeded and not insured (i.e., the insurance is delayed). If the oil is too dirty, the impurities in the oil will accelerate the wear of the engine cylinder.

2. Too much oil is added. 3. Improper selection of air filter element, machine filter element, engine oil, etc., the gas impurities entering the cylinder can not be well purified, and all kinds of dust particles enter the cylinder, accelerating the wear of the cylinder. The quality of the filter element is poor and does not play the role of the magazine in the filter oil.

Counterfeit engine oil or the oil used does not match the oil grade of the vehicle used, so that it will not be able to form a good oil film on the friction surface of the engine. 4. The ignition time is too early or too late. Premature or late shock will increase the temperature of the engine, and in severe cases, the piston will fall off the top and the cylinder block will be scrapped.

In its initial stage, there will be serious cylinder blow-by gas and burning engine oil. 5. There is too much dirt in the water tank in the cooling system. The radiator and condenser are too dirty, which reduces the ventilation and heat dissipation capacity, and increases the normal working temperature of the engine.

Due to the high temperature, the quality of the oil film produced by the lubricating oil during friction decreases, and the wear of the cylinder is intensified. To sum up, in addition to the natural wear and tear of the vehicle with the increase of vehicle mileage and the generation of engine oil, active maintenance and reasonable use of the vehicle can avoid the early arrival of the cylinder blow-by phenomenon and prolong the service life of the car.

In fact, the root cause of burning engine oil is that the domestic fuel quality and engine oil quality are too poor. The fuel is poor, everyone should still have a number in mind, but the oil is poor, a little bit I don't understand. In Europe, there must be 22% additives in engine oil, and the content of additives is as follows

Typical multigrade motor oils – 78% base oil, 10% viscosity improver, 3% detergent, 5% dispersant, 1% wear protection, 3% other components; The content of domestic oil additives does not exceed 15% at most, or even less. The poor quality of the engine oil not only does not clean away the dust inhaled into the air during the operation of the engine and the carbon deposits formed after combustion, but also the combination of gum and other impurities formed by self-oxidation will lead to the formation of more carbon deposits. These carbon deposits are deposited in the piston, which affects the outward elastic tension of the piston ring, causing the cylinder pressure to deteriorate. If it is deposited in the engine, it will cause poor lubrication, increased wear, increased fuel consumption, decreased power, and cause oil burning.

Burning engine oil is not a terminal disease, and burning engine oil is completely preventable, and the cost of prevention is also the lowest. The prevention method is also very simple, one is to regularly add Matti BE and Matti F to gasoline to keep the fuel system clean, inhibit carbon deposition, and improve combustion efficiency; The second is to add Marty M to the engine oil to improve the performance of the oil, such as cleaning, lubrication, protection, temperature control and other functions are more powerful, reduce engine dirt, avoid wear, so as to solve the problem of poor fuel and oil quality, and there is no need to worry about burning engine oil in the future. Whether to burn engine oil or not, the key is to learn to prevent it.

If the oil has already been burned, it must be solved as soon as possible. At present, there are two more popular ways to find land for overhaul, the quality of accessories, the level of technicians can be guaranteed, and the cost can be afforded, you can try, but after the overhaul, it will inevitably cause damage to the engine, which is common sense, the car is not broken, it is repaired!

The second is not to overhaul the solution, because the root cause of burning engine oil lies in the poor quality of oil and oil, resulting in excessive carbon deposits, which causes a series of problems such as piston ring stuck, cylinder wall wear, oil seal aging, etc., so as to burn engine oil, through high-quality cleaning and repair technology, such as the more popular German Marty, can solve these problems, do not overhaul can also solve the problem of burning engine oil, and solve the quality of gasoline and engine oil from the root, to ensure that there will be no more **.

Hello When the piston ring is worn and the gap between the cylinder liner is too large, the oil will escape to the combustion chamber and burn the oil.

Cars, generally need to lubricate the engine, when climbing, consume a little oil.

Under what circumstances does a car burn engine oil?

The main reason for burning engine oil

1. There is a problem with the accessories, the waste valve, the valve seal, the cylinder is pulled in the cylinder, and the cylinder pressure is insufficient.

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

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 first confirm the cause of burning engine oil 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 cylinder pressure 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 for two consecutive times, plus to find a good road condition to run in separately, 3000-5000 kilometers to complete the run-in, the cost of oil + gasoline is very high, and the cost of overhaul and run-in of ordinary cars 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.

Decrypt the correct inspection methods and repair plans for burning engine oil.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Cars burn engine oil. One is that the piston wear gap is larger. The other one is piston ring grinding.

The gap is bigger. In this way, the oil can be burned. Change the cylinder liner or fire plug ring immediately. It won't burn.

Clause. 1. Aging of valve oil seals.

If the vehicle starts in the morning, there is blue smoke from the exhaust pipe, and the blue smoke disappears after a period of time, it means that the engine oil is burned when the engine is started, and this situation is most likely due to the broken valve oil seal. The valve oil seal is a component installed on the valve guide rod, and its function is mainly three: one is to seal the intake and exhaust valves to prevent the oil or exhaust gas in the cylinder from leaking from the intake and exhaust valves, the second is to prevent the oil from entering the cylinder, and the third is to prevent the oil from entering the intake and exhaust pipes.

If the valve oil seal is broken, the oil will seep into the cylinder along the valve guide rod and mix with the fuel to burn, and the engine will emit blue smoke. The valve oil seal is a rubber part, which will deteriorate after a long period of use, affecting its tightness. In addition, if there is a problem with the oil seal of the vehicle with a small number of kilometers, it is most likely that the oil seal structure is damaged during installation, or foreign matter enters, resulting in damage to the seal and causing the oil to enter the combustion chamber.

Clause. Second, the exhaust valve is damaged and aging.

When the engine is running, the high-temperature and high-pressure gas in the cylinder will be drilled into the crankcase from the tiny gap between the piston and the cylinder block, and the oil in the crankcase will also produce some oil vapor due to the high temperature, and the exhaust valve is to screen these mixtures, leave the usable oil in the crankcase to continue to use, and discharge the "undigested" exhaust gas to the intake manifold, and then enter the cylinder for secondary combustion.

If the exhaust valve fails, it is impossible to separate the oil from the crankcase mixture, which transfers the oil vapor and fuel mixture to the intake manifold and then into the cylinder for combustion. In this way, the wastegate is equivalent to losing the ability to "screen", and to exaggerate, it is equivalent to connecting the pipe from the crankcase to the intake manifold, which will not only cause a serious waste of oil, but also increase the carbon deposit of the engine and make the power worse.

Clause. 3. The accessories in the cylinder are damaged.

If you find that the vehicle emits blue smoke when accelerating, it is likely that the piston rings in the cylinder are worn and the engine oil is burned. Due to the increase of carbon deposition in the cylinder, the oil seal ring and air seal ring of the piston will be wrapped in carbon deposition, losing the original sealing function, and the cylinder block will also be scratched by carbon deposition, and the overall airtightness will be greatly reduced. Compared with the above two cases, in the case of damage to the accessories in the cylinder, the maintenance is the most troublesome, and the engine needs to be dismantled.

The accessories in the cylinder lose their sealing effect, and the oil in the crankcase will flow into the cylinder through the gap between the cylinder block and the piston, and burn together with the fuel, and the high-temperature and high-pressure gas inside the cylinder will also flow to the crankcase, and finally lead to the decline of the vehicle's dynamic performance. In addition, the usual use of inferior engine oil will also cause accelerated wear and tear of the cylinder block, so be sure to choose the best engine oil.

At last. In fact, engine oil burning is often caused by inconspicuous small problems, and these small problems are mostly caused by not paying attention to inspection and maintenance. Therefore, the car must be regularly inspected and maintained, and it is not possible to delay time because it is "still okay".

Driving with a fluke mentality, many times it is to save a small amount of money and spend a lot of money, and the best state is to prevent problems before they happen.

There are four common reasons for burning engine oil.

1.If you don't clean the oil circuit for a long time or don't do effective oil circuit cleaning, detergents are used at will, and using detergents and effective detergents are two different things;

2.The antifreeze replacement cycle is too long or not changed at all;

3.The oil change interval is too long;

4.Long-term or often short-distance driving.

I believe that Volkswagen and Audi owners can only say two words in the face of their car burning engine oil: helpless!

My Magotan began to burn engine oil about 100,000 kilometers, burning one liter from 5,000 kilometers, to the standard of the Volkswagen manual: burning at 1,000 kilometers, looking for a 4S store, saying that it is normal. Next is 1000 kilometers to burn 1L, Volkswagen said that the warranty period, can only be overhauled, it seems that the Volkswagen car burns the engine oil is stuck in time, after the warranty period to burn the oil, a belly fire does not know how to vent.

I began to look for information on the Internet, saying that the German Ma can be solved, according to the "prescription" prescribed by others, I asked my friends in Germany to bring a set of additives and engine oil from Germany, and added them with hope, observing that 1000 kilometers are useless, 2000 kilometers are useless, 3000 kilometers are useless, and 5000 kilometers are useless. The money is not spent, and the oil has to be added vigorously. The key is a vicious circle, and the oil alarm has reached 700 kilometers within a few thousand kilometers.

I saw that online riders burned to the limit, burning a liter of engine oil for 200 kilometers, and the car couldn't be driven! What if it gets to this point? It's really disturbing!

Having said that, there is nothing wrong with this car except for burning engine oil, and the power of 140,000 kilometers is only slightly reduced to now. If it is overhauled, 100,000 are unwilling. If it is 300,000 kilometers, to the standard overhaul mileage, the overhaul will be overhauled, but it is only 140,000 kilometers, and it really can't be overhauled.

In May 2020, it was found that the technology of non-dismantling engine without dismantling and treating engine oil burning appeared on the Internet. There are two technologies: one is to heat and dismantle the oil pan, which I was very disgusted with dismantling the engine, and to heat it in the cylinder in a cold car state, the oil and water channels are not circulating, and it is terrible to make an accident.

In addition, this product is very corrosive, and the reason why the oil pan is removed is because it is afraid of corroding the paint of the oil pan. If it heats up for a few hours, the cylinder liner and piston are also corroded, and the strength decreases, then it will be afraid.

The other technology does not need to be heated, is weakly alkaline, does not corrode, and does not cause harm to the first technology, which basically avoids the defects of the first technology. And it is a ** transaction, not a cash transaction, Alipay guarantee, and there is a written warranty. Like the overhaul warranty of the 4S shop, it is guaranteed for 30,000 kilometers a year.

I think if this technology is not mature, I dare not use the ** transaction method, after all, the seller is risky. On the other hand, if you dare to use ** to trade, you must have two brushes. At the same time, the seller provided a successful case, and the owner's ** communicated in detail with several car owners, which was more practical.

Clapper decided to try, anyway, there is no other way, a dead horse should be a live horse doctor.

Burning engine oil is not a terminal disease, there is a way to solve it, and it is not necessary to overhaul the engine. 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 and drive more, you can clean the carbon deposits on the top of the piston and release the piston ring.

The company has a link to teach you to prevent burning engine oil.
