What is the general situation of burning engine oil in a car?

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:

1. 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.

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.

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 wall clearance, etc., all have a direct or indirect relationship with 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 to achieve no dismantling and repair to solve the problem of burning engine oil.

1. Burning engine oil in a cold car: When the temperature of the car is not completely warmed up, the engine exhaust pipe emits a lot of blue smoke, but it is normal after the car is heated. This phenomenon is caused by the aging of the valve oil seal.

Due to the decrease in temperature, the valve oil seal of the rubber material is stiff and cannot be completely sealed, and the oil leaks from the valve into the combustion chamber and burns.

Solution: Remove the engine cylinder head and replace the valve oil seal (please rest assured, this belongs to the repair project.) The repair time is about 4-5 hours. The cost ranges from 800 yuan to 1200 yuan, depending on your car).

2. Hot car burns engine oil: After the car reaches the normal temperature, the exhaust pipe still emits blue smoke, which indicates that the piston ring has a poor seal. Due to the poor sealing of the piston ring, the oil directly enters the combustion chamber through the piston ring leakage under the action of the oil pump, and there is a phenomenon of blue smoke from the exhaust pipe.

There are several reasons for this phenomenon, such as: material aging, carbon deposition jamming, excessive wear of cylinder liners, etc.

Solution: According to the normal operation method, the engine needs to be lifted down for overhaul operations. The repair time is about 2-4 days. The cost ranges from 5,000 yuan to 20,000 yuan, which needs to be combined with your car, and the cost is mainly high in accessories.

In addition, there is another way to deal with it: if it is determined that the oil is burning in a hot car and it is not very serious (for safety reasons, the cylinder pressure test can be carried out first), the oil pan can also be removed directly, the piston can be directly taken out, and the piston ring can be replaced, so that the cost and time are similar to the first solution.

1. Burning engine oil in the car is harmful to some parts of the car, but it will not be wasted. For the use of engine oil in cars, many car owners will have a misunderstanding, thinking that this will only consume more oil, will not cause any harm to the car, and also think that it is beneficial to the engine. As everyone knows, this idea is wrong, the use of engine oil will not only waste more, but also because of the excessive combustion of oil, resulting in some parts are not completely burned out, thus forming carbon deposits, resulting in the emission of harmful substances contained in the exhaust of the car exceeds the standard, endangering the air, ecological environment and ecological quality, as well as human health.

2. The core reason for burning engine oil:

1.Domestic oil products and road conditions can easily produce carbon deposits (the source of automotive problems).

2.Carbon deposition causes the piston ring to jam and lose its oil scraping performance; The oil return hole is blocked, and the oil cannot return to the crankcase normally.

3.Wear between the cylinder wall and the piston, the gap is too large.

4.Corrosion and aging of valve oil seals and crankshaft seals cause oil leakage.

Engine parts are damaged, wear and tear is severe

Hello, the car burns the engine oil for a period of time, the oil will be reduced, and the exhaust pipe of the oil burns blue smoke, I hope mine will help you!

How Volkswagen and Toyota choose.

Three types of oil-burning phenomena are classified

1. When the car is first started in the morning, there is a thick blue smoke in the exhaust pipe, and the blue smoke disappears after a while, and this situation may not occur again on the same day, but this phenomenon occurs again in the morning of the second and third days, which indicates that the vehicle has burned engine oil, which is called burning engine oil in a cool car.

2. When the vehicle is driving or on the spot, the exhaust pipe emits a large amount of blue smoke when the driver slams on the accelerator, which indicates that the phenomenon of the vehicle burning engine oil has been more serious, which is called accelerating the burning of engine oil.

3. In addition to the blue smoke coming out of the exhaust pipe, you can also see pulsating blue smoke coming out of the oil port of the processor. In this case, the damage to the engine is already severe.

Analysis and solutions

Burn the oil"This is when the oil enters the combustion chamber of the engine and participates in the combustion along with the gas mixture. Vehicles appear"Burn the oil"The phenomenon will cause the vehicle oxygen sensor to be damaged too quickly, resulting in an increase in carbon deposition in the combustion chamber, unstable idling, weak acceleration, rising fuel consumption, excessive exhaust emissions and other adverse consequences.

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. However, it has happened that the engine lives by oil and burns the engine seriously, so it is recommended to check it first, and don't be in a hurry to deal with the engine problem blindly.

Burning engine oil will lead to shaking, 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 on the main line.

If it is delayed, it will cause the oil to participate in more and more combustion, and finally pull the cylinder, because the oil participates in the combustion, there are more oil components in the mixture, and the load of the three-way catalysis is too large, and the three-way catalysis will be replaced in advance, and the three-way catalysis is very expensive, which will lead to a sharp increase in costs. The result of relying on oil to continue life is that the cylinder must be dismantled, the engine must be dismantled, the engine must be overhauled, and the valuable three-way catalysis must be replaced in advance.

Therefore, starting from the oil circuit to solve the problem is the way to eradicate the root. But not casually, the oil circuit cleaner does not have the function of releasing the piston ring, let alone using something like PEA, and do not clean the carbon deposits in the cylinder separately. If you want to use a PNF-type cleaner, you can release the piston ring.

Prevention of engine oil burning and solutions.

The reason why burning engine oil is ignored by many people, the second episode, interprets the reason for burning engine oil from the essence, knowing the essential cause can help us correctly prevent burning engine oil and solve the problem of burning engine oil. Avoid detours.

The possible causes of engine oil burning are du

Many, the most common zhi

There are the following:

1. Use DAO oil with poor quality or viscosity that does not meet the requirements of the internal grade. 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.

If it is a two-stroke, the oil and gasoline are mixed together, and if it is a four-stroke, the engine cylinder liner is worn or the air ring and oil ring on the piston are worn, and the cylinder needs to be bored or the air ring and oil ring replaced.

Summary of the 4 core reasons why cars burn engine oil::

Carbon deposition in the combustion chamber, domestic oil and road conditions are easy to produce carbon deposition;

The carbon deposition causes the piston ring to jam, loses the right to scrape the oil, and causes the seal to be not tight; The oil return hole is blocked, and the oil cannot return to the crankcase normally;

The wear of the cylinder wall and the piston ring, the gap is too large.

Corrosion aging of valve seals and crankshaft seals.

The above is the core reason for burning engine oil, of course, there are some other reasons, and now the problem of burning engine oil can be solved by using the German Marty non-dismantling and repair method, without damage to the car in the overhaul.

The normal loss of engine oil is not called burning engine oil, and the loss of engine oil exceeding the specified range is called burning engine oil, which is certainly not normal, indicating that there is a problem with the engine and the rock wheel.

It's no problem to have a little less, but if you have too much, you need to check the problem, and the old car will burn a little bit, depending on the condition of the car.

Burning engine oil is obviously not normal.

German cars can be somewhat consumed, and there is no problem with other car series.

<> "What is the general reason for burning engine oil in automobiles?

1. The engine has too much carbon deposit. Excessive carbon deposition leads to piston ring stagnation, and the oil on the cylinder wall cannot be effectively scraped off during engine operation, resulting in oil burning.

2. The valve oil seal is damaged. The valve oil seal is damaged, causing the oil lubricating the camshaft and other parts on the cylinder head to enter the cylinder along the intake valve, resulting in oil burning.

3. The crankcase ventilation valve is damaged. If the crankcase vent valve is damaged, a large amount of oil will enter the cylinder to participate in combustion, resulting in oil burning.

4. The oil seal of the turbocharger is damaged. When the turbine oil seal is damaged, the oil will enter the turbine intake or exhaust side, causing the engine oil to burn.

5. Mechanical failure, abnormal wear and tear of the engine, so that the cylinder is seriously pulled by Bichun, and the piston ring cannot effectively scrape off the oil of the cylinder wall during the operation of the engine, resulting in the burning of engine oil.

Now Senqiao's car burns engine oil, which is generally caused by the first four reasons. Due to the qualitative leap forward in today's industrial technology and materials, there are very few cases of burning engine oil due to mechanical failures.

The situation of burning engine oil in automobiles is: 1. The oil consumption is too fast. We can also check the remaining amount of oil through the trip computer or the traditional dipstick of the filial pietro.

If you find that the oil is depleting significantly too quickly before the maintenance date, you need to pay attention. If there is no oil leakage in the engine, it is basically the phenomenon of "burning oil";

2. When the car starts coldly in the morning, the exhaust pipe appears blue exhaust gas, which disappears after running for a period of time, and the engine may have a slight sign of burning oil. When the engine does not run for a long time, the oil will flow into the cylinder through the gap of the valve oil seal under the action of gravity. At this time, once the engine is started, the oil in the cylinder will participate in combustion with the fuel under the action of high temperature and high pressure, producing a large amount of blue smoke;

3. Qiaomu now has some good cars, the central control dashboard can see the amount of oil, ordinary family cars, the simplest is to do maintenance, the oil is near MAX, the car is driven out of the fast repair shop for 1000 kilometers, come back to check if only half, it is to burn the oil;

4. Lower quality engine oil will reduce the working efficiency of the engine, increase the degree of carbon deposition of the car, increase pollution, and reduce the service life of the car. The use of appropriate high-quality engine oil will reduce the friction between the engine and various components, and reduce the overall oil use while ensuring the efficiency of the automobile engine;

5. Note: Do not hold the oak and use gasoline or kerosene to clean the honed cylinder wall. Because they are unable to remove abrasives that adhere to the cylinder walls, they can lead them into the honing micropores.

As a result, cylinder liners that have not been properly cleaned can cause premature wear, piston ring failure, and ultimately increased oil consumption.
