Causes and solutions for burning engine oil in automobiles

Causes of burning engine oil

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

Carbon deposition is indispensable in the combustion process, and carbon deposition is the root cause of some automobile failures, such as the aging of valve seals, piston wall clearance, etc., which are directly or indirectly related to the formation of carbon deposition, so keeping the fuel oil circuit clean is of great help to prevent burning engine oil, of course, this needs to be done with the help of high-quality fuel additives.

3. With the help of external forces

The cleanliness of the fuel oil circuit and the anti-aging degree of the engine oil are basically the key to determining whether the engine oil can be prevented, so considering the relationship between domestic oil products, it is necessary to use high-quality engine oil and fuel additives to achieve, which is also the key to realizing the solution of burning engine oil without dismantling and repair.

The core reason for burning oil:

1.Domestic oil products and road conditions are prone to carbon accumulation (the root cause of automobile problems).

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

3.Excessive wear and clearance between the cylinder wall and the piston.

4.Oil leakage caused by corrosion and aging of valve oil seals and crankshaft oil seals;

the phenomenon of "burning engine oil";

Phenomenon 1: The main manifestation of "burning engine oil" is the exhaust of blue exhaust gas from the tail when driving, which indicates that too much engine oil enters the combustion chamber to participate in combustion.

Phenomenon 2: The oil dipstick detects that the oil consumption is too fast.

Detection method: After the cold car is started in the early morning, check whether the exhaust pipe will emit blue smoke; Whether there is a large amount of blue smoke coming out of the exhaust pipe when the vehicle is driving or when the accelerator is pressed on the spot; In addition to the exhaust pipe, the oil port also emits blue smoke from time to time.

Therefore, it is necessary to check the oil level regularly and add the right amount of oil as needed.

In the normal operation of the car, after the oxidation of gasoline additives, a gelatinous substance will be generated, and after the fuel injector enters the extinguishing chamber and is extinguished, it will constitute carbon deposition in the intake valve, piston top, piston ring groove, extinguishing chamber, spark plug and other parts, which will aggravate the aging of these parts and cause the burning of engine oil.

Solution; The inherent method of direct overhaul, now burning engine oil does not necessarily have to be overhauled, many car owners have not solved the problem after overhaul, and there are other problems in the car. You can place a "zero dismantling and non-destructive repair to solve the problem of burning engine oil", and there is no need to disassemble and repair to solve the problem of burning engine oil, which will not cause any harm to your car.

processing methods; 1. The owner should replace the valve oil seal of the vehicle in time to ensure the valve tightness. The valve oil seal will be aged and seriously worn out after long-term use, and the vehicle with a longer service life or more kilometers is more likely to burn engine oil; 2. The oil with appropriate viscosity can increase the tightness between the engine piston and the cylinder wall, and the use of this oil can alleviate the phenomenon of oil burning, but it cannot be completely eliminated;

3. Replace the piston ring of the car, and regularly clean the carbon of the surface area of the piston ring;

4. Check the oil ruler frequently, and the scale of the oil ruler is generally added to the best between 4 and 5, that is, eighty percent of the position, too much or too little. In addition, regularly replace the oil and oil filter spare parts according to the requirements of the product manual; 5. Choose high-end or high-quality engine oil, especially for engines with turbochargers, because its higher operating temperature and higher oil requirements. Choose an oil with a low volatility rate, as oil volatilization can also cause the car to burn oil.

In addition, choosing a fully synthetic engine oil can greatly reduce the phenomenon of burning engine oil;

6. Develop good driving habits, especially for new cars during the run-in period, the speed should not exceed 90 kilometers per hour, and the engine speed should not exceed three-quarters of the maximum speed.

Through the above methods can solve the phenomenon of engine oil burning, the owner should avoid the above wrong methods in daily maintenance, and prolong the service life of the engine.

The main reason for burning engine oilIt is the problem with the fittings, the wastegas valve, the valve seal, the cylinder pulling the cylinder, and the cylinder pressure is insufficient.

It is a long-term unclean oil circuit, the antifreeze is not replaced in time, the oil service life is too long, the piston ring is stuck, and the more common situation is that the piston ring is stuck.

Causes of piston ring seizureStagnation 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.

ResolutionThere are two ways to solve the problem of burning engine oil, one is overhaul, and the second is PNF repair agent. If you don't have serious cylinder pulling, engine damage you don't need to overhaul. First of all, you need to find out the reason for your burning oil, if it is not a fault of the accessories, clean the oil circuit with additives, and release the piston ring.

There have been riders who have repaired it with a 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.

For car owners, there is a problem that bothers them consistently, that is, burning engine oil, basically many cars will have this situation, so when car owners buy a car, they will consider whether it burns engine oil. I want to tell you that 95% of the cars on the market will burn engine oil, and at the beginning may burn very little, 1,000 kilometers, but in the later stage, it may become 1L for 1,000 kilometers. So how to solve the problem of low engine oil?

I'm going to tell you about it today. What should I do if my car burns engine oil? 2 tips to help you solve it, and you don't have to spend money in vain!

First of all, we have to judge whether your car is short of engine oil, we observe whether a car burns engine oil, or to see its exhaust, whether it emits blue exhaust, if so, then prove that your car burns engine oil.

The main principle of its operation is that a large amount of blue smoke is emitted from the exhaust during driving: mainly because of the poor sealing between the engine piston ring and the cylinder wall.

When the vehicle accelerates rapidly, the frequency of the piston ring moves up and down accelerates, and the residual lubricating oil on the cylinder wall is easily brought into the combustion chamber by the piston ring, resulting in the phenomenon of "burning engine oil". So how to solve the problem of burning engine oil? Here I will give you two methods.

Special restorative agents are generally used, but they can be broadly divided into these two categories.

The first category: melting and casting.

It is mainly through soft metals or other special materials, attached to the friction surface instead of the original metal friction, on the one hand, to enhance the sealing, on the other hand to protect the original friction surface metal. However, these additives may be useful in the early stages, but over time, the effect will be greatly reduced.

The second category: forging.

It mainly forges the metal on the friction surface through the high temperature and high pressure inside the engine to form a new friction surface, increase the size of the original workpiece, strengthen the seal, and protect the original friction surface. But there is a disadvantage, that is, it is very rare, you need to look for it slowly, if the amount is enough, it can be completely closed directly, so that your engine will never be less 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:

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. Maintain the engine according to the mileage specified in ZD, which 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 it cannot play the role of filtering impurities in the oil. Counterfeit engine oil or the oil used does not match the oil grade of the vehicle used, so that a good oil film will not be formed on the friction surface of the engine.

4. The ignition time is too early or too late. Detonation occurs too early or too late, which increases the engine temperature, 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 when rubbing is reduced, and the wear of the cylinder is intensified.

Causes 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.

Hope it helps.

Pay attention to these components when burning engine oil in automobile engines.

The general situation of burning engine oil in a car is that there is a problem with the engine, and it is best to go to an outside repair shop to check it.

It is generally caused by the piston ring or valve oil seal, which needs to be carefully checked, and many of them have the phenomenon of burning engine oil, but it is not a serious problem, and a slight burning of engine oil is generally acceptable.

If you don't plan to use this car for a long time, you can change the valve seals and piston rings, and you can run for a year.

If you want to use the car for a long time, do an engine overhaul.

There are many reasons for burning engine oil, such as piston rings, valve seals, boosters, check valves, etc. Therefore, further investigation is needed to determine what is causing the problem and avoid unnecessary troubles and unjust money.

The first thing to determine is whether it is caused by external parts of the engine, such as exhaust valves, turbochargers, etc., which are easy to deal with. If not, it is the internal piston piston ring or valve seal inside the engine, which is more difficult to deal with.

The car stops and goes, not only will there be traffic congestion, but also the owner of the car who knows a little about car maintenance will also find that this will make the car burn the engine oil.

Automobile oil burning means that the engine oil enters the combustion chamber of the engine and participates in the combustion together with the mixture. If the vehicle burns engine oil, it will cause the damage of 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, excessive exhaust emissions and other adverse consequences. The most serious consequence of burning engine oil is that the engine is under-lubricated, causing irreparable damage or scrapping of the engine.
