Why burn engine oil? What causes burning engine oil?

Reasons for burning engine oil: long-term unclean oil circuit, untimely replacement of antifreeze, and too long oil service cycle.

The harm of burning engine oil: it will continue to generate greater carbon deposits, which will seriously pull the cylinder. The three-way catalytic converter is completely damaged in the poor combustion exhaust gas,,, and the continuous life-sustaining oil will eventually cause the engine to burst the cylinder.

The three points of the car that burn the engine oil will inevitably occupy one point, and the most important point is the high temperature caused by the oil circuit not being effectively cleaned.

Causes of piston ring seizure.

The oil used for the stuck piston ring will be caused by the oil scraping not clean and remaining on the cylinder wall, causing the oil to participate in combustion and burn the oil. Among them, the cylinder wall will be seriously worn due to the delay in processing, and the engine will have to be disassembled.

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.

At present, the effective method is to use the oil burning oil repair agent of the original solution of the company to clean the oil circuit and the cylinder, and release the carbon sludge stuck in the piston ring by penetrating into the piston ring. For most of the vehicles where the piston ring does not have a counterpart, the stagnation can be completed as long as it is repaired in this way, and the oil wiping function can be restored to improve the phenomenon of burning oil.

My colleague's car is also burning engine oil, the exhaust valve is fine, planning to release the piston ring, directly using the Si Youpu stock liquid type of burning engine oil repair agent, after 5 times in a row, from the previous 1200 kilometers plus a liter of engine oil to the current 6000 kilometers without adding oil, the price comparison, overhaul is the most such an effect. The cost is only one-tenth of that of an overhaul, and the residual value of the car is maintained.

Hello, as long as the internal mechanical cooperation of the engine is too large, resulting in the burning of engine oil. Hope it can help you

How Volkswagen and Toyota choose.

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.

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 oilIn two aspects, one is that there is a problem with the accessories, the waste valve, the valve oil seal, the cylinder is pulled in the cylinder, 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. 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.

SolutionThere 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, oil circuit blockage, carbon deposits, piston ring stagnation can be repaired with repair agent, there are riders who have repaired it with repair agent before, you can refer to it.

Not a major overhaul to solve the problem of burning engine oil.

Summary and solutions for burning engine oil for various models.

"Burning oil" means that the oil enters the combustion chamber of the engine and participates in the combustion along with the gas mixture.

Generally, vehicles with the phenomenon of burning engine oil will have different degrees of exhaust "blue smoke" symptoms, oil consumption increases significantly, and the engine oil has to be replenished in a short period of time. The phenomenon of burning engine oil in the vehicle will lead to an increase in carbon deposition in the combustion chamber, a decrease in the economy and power of the vehicle, and excessive exhaust emissions.

The poor sealing of the cylinder is the main reason for the burning of engine oil; The poor sealing of the cylinder is mainly due to the excessive matching gap between the piston and the cylinder wall, the improper installation of the piston ring or the poor sealing, and the oil on the cylinder wall enters the combustion chamber, causing the phenomenon of burning oil. In addition, poor sealing performance of the valve seal, damage to the crankcase vent valve, or crankcase vent blockage will cause the oil to enter the cylinder with the crankcase gas to participate in combustion.

For some old cars, it is normal to have different degrees of oil burning due to the increase in the wear gap between the piston and the cylinder wall, and we can appropriately choose the oil with slightly larger viscosity to increase the tightness between the piston and the cylinder wall. Of course, the ultimate solution to the problem of burning engine oil is to overhaul the vehicle more thoroughly and fundamentally solve the problem.

Increase the throttle to keep the engine running at high speeds, and if a large amount of blue smoke is emitted from the exhaust pipe, it means that the organic oil has entered the combustion chamber for combustion. If smoke is also seen at the oil filler at the same time (generally pulsating smoke), the piston connecting rod group should be removed for analysis and inspection, especially the clearance, backlash and side clearance of the first ring. If these gaps are too large, it is easy to aggravate the pumping phenomenon.

In another case, the exhaust pipe of the engine is running under heavy load, but the fuel port does not smoke, which is the result of entering the combustion chamber along the gap of the valve guide. In both cases, repairs or treatments should be carried out.

It is normal to burn engine oil. The engine oil is equivalent to the blood of the car, bringing endless power to the car and braking. Engine oil is indispensable for machine lubrication, especially for the engine.

Too much or too little is not good, generally the highest liquid level is a little lower, and it is necessary to check regularly.

Before the inspection, the vehicle should be parked on the horizontal plane, and the engine should be started to idle for 5 mis "minutes";

Stop the engine, wait for 3 mis, pull out the oil dipstick and wipe it clean, reinsert the dipstick and take it out again, and record the oil level on the dipstick;

The correct oil level should be between the highest and lowest positions;

Beat the oil on the dipstick with your hand and check its viscosity to see if there is any gasoline smell and bubbles;

If the oil level is too high, even if the reason is inquired, it should be ruled out, and the cause may be caused by cooling water or gasoline entering the crankcase.

Five misunderstandings about the use of automobile engine oil:

Myth 1: Engine oil is often added but not changed.

For some German oil-burning car owners, it is not wrong to check the engine oil frequently, but only replenishing and not replacing can only make up for the lack of oil quantity, but cannot fully compensate for the loss of lubricating oil performance. During the use of engine oil, the performance will gradually decrease due to pollution, oxidation and other reasons, and there will also be some consumption, so that the quantity will be reduced.

Myth 2: The role of engine oil additives is large.

A good quality oil is a finished product with a variety of engine protection functions, and the formula already contains a variety of additives, including anti-wear agents, and the oil is most important to balance the formula to ensure that the performance is fully realized. Adding other additives by yourself not only does not bring additional protection to the vehicle, but is easy to react with the chemicals in the oil, resulting in a decrease in the overall performance of the oil.

There are two reasons for 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. It 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.

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.

Supplement] How to tell if you burn engine oil.

1. Check whether there is blue smoke from the exhaust emissions;

2. Check whether there is often less oil.

What are the reasons for burning engine oil?

Burning engine oil is divided into the following situations; 1.The exhaust valve is damaged, and the oil exhaust gas enters the combustion chamber, causing the oil to burn. Judgment method: Disassemble the intake pipe and check whether there is obvious oil stain near the exhaust valve. Solution: Repair or replace the exhaust valve.

2.Excessive clearance between the engine valve and valve guide or poor sealing of the valve oil seal causes oil to enter the combustion chamber from the valve position, resulting in oil combustion. Inspection Method:

3.The engine's cylinder gasket burns through, causing oil to leak through the oil circuit into the combustion chamber, burning the oil. Judgment method:

Remove the spark plug and check the cylinder pressure. If the air pressure of two adjacent cylinders is similar and the air pressure is lower than the standard value, there will be air leakage in the cylinder, which may cause oil leakage. Workaround:

Replace the cylinder gasket.

4. The gap between the piston, piston ring and the cylinder wall is too large, which causes the oil to enter the combustion chamber for combustion. Judgment method: get on the car and pull out the dipstick to observe whether there is blue gas spraying out of the dipstick mouth. Yes, burn the engine oil; No, don't burn oil.

Workaround:: There is a solution to the current market. One is overhaul, and the other is PNF repair agent. The general car does not need to be overhauled without serious cylinder pulling, and the repair agent can be repaired.
