Why do cars burn engine oil? Why do cars burn engine oil?

The car is old. The engine will wear out during use, the piston will become smaller and smaller, the cylinder will become larger and larger, the piston ring will be thinner and thinner, the oil scraping effect will be worse and worse, and the oil will run into the cylinder and burn. Commonly known as:

Cylinder oiling. Solution: Replace the ring, if it can't be solved, then change the four supporting (cylinder barrel, piston, ring, Xiao) can be solved.

Cars that burn engine oil generally emit blue smoke from their exhausts, which is clear at a glance.

You still have a certain amount of professional knowledge in this question, that is to say, the car has played a very important role in people's lives, and it is relatively fast and convenient, but with the growth of the service life, the car will have the problem of burning engine oil, and the main reason for it is that the steel drum fire is completed by using a unique metal, and then in the case of high temperature. The piston movement back and forth in the cylinder barrel generates power, so it will produce a certain amount of wear and tear, and the amount of wear will increase, and there will be some oil in this gearbox in the future, and these muscle oils are for good lubrication. Because of the wear of the cylinder barrel piston, the muscle oil will go to the combustion chamber above, and then burn after high temperature, so the main reason for the car to burn the engine oil is that the wear of the cylinder barrel piston is relatively large, and it needs to be replaced in time.

The operating temperature of the car rises, and the machine.

Oil is used as a lubricating and cooling fluid.

The body will naturally be vaporized.

The reasons for burning engine oil in automobiles are natural wear and tear, oil problems, etc. The specific reasons are as follows: Natural wear and tear:

As the mileage of the car increases, the wear between the piston and the cylinder gradually increases. When this wear increases to a certain extent, the blow-by of the cylinder begins, and the phenomenon of burning oil will occur. When the valve oil seal is damaged, the oil burning phenomenon will be more obvious.

Oil problem: If the oil is too dirty, the impurities in the oil will accelerate the wear of the engine cylinder, causing the oil to burn; The amount of oil added is too large, the oil is not selected properly, such as fake oil or the oil used does not match the oil grade of the vehicle used, so that the engine surface can not form a good oil film, and the cylinder burns the 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

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.

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.

Solutions to the problem of burning engine oil in the engine link.

The reasons why the car burns engine oil badly: 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.

Hello, if the car burns oil, it means that the gap is too large to cause the oil to burn or the valve oil seal is not tightly sealed.

There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc. In addition, there are now crankcase ventilation systems (exhaust valves) in cars, which can also exacerbate oil consumption if there is a problem.

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. It is relatively normal for some old cars to burn engine oil, and the oil with slightly higher viscosity can be appropriately selected to increase the tightness between the piston and the cylinder wall.

Most of the car burning oil is due to the improper operation of the driver or the maintenance is not timely, it is easy to cause serious engine wear, steel sleeve 4 matching or crankshaft oil seal leakage. He is prone to burning engine oil.

Usually we say that the engine is the heart of the car, so it must be cared for. The quality of the engine oil plays a crucial role in the engine. High-quality engine oil can not only effectively reduce engine wear and improve engine operating efficiency, but also save fuel consumption, extend oil change intervals, and help keep the engine clean, prolong the service life of the engine, make the long-term performance of the engine as new, and virtually save maintenance costs.

Burning engine oil, a phenomenon that is now prevalent between new and would-be new cars. "Burning engine oil" is very harmful to the vehicle, not only will the vehicle oxygen sensor be damaged 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, in serious cases, due to insufficient engine lubrication, the engine will cause damage that is difficult to repair or even scrapped, resulting in a significant increase in maintenance costs, and even potential accidents.

1. Normal engine fuel consumption is necessary to maintain the operation of the engine, all will not cause harm to the engine, the engine in the process of operation "burning" oil and "burning" gasoline is the same normal phenomenon, for most models in the new car after 1000 kilometers, under good working conditions to maintain the oil consumption of the trolley in 1 liter 1000L, large car 2 liters 1000L are normal.

2. The viscosity selection of the engine oil has an impact on the oil consumption, if the viscosity is not enough to form a complete oil film to ensure the sealing between the piston ring and the cylinder wall, the oil consumption will increase. For engines with high piston ring and cylinder wall wear, a higher viscosity oil is required.

3. When the car is first started in the morning, the exhaust pipe appears a thick blue smoke, and the blue smoke disappears after a while, and this situation may not occur 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. (Valve seal failure is the world's rent master).

4. When the vehicle is driving or on the spot, the exhaust pipe emits a large amount of blue smoke when the driver steps on the accelerator, which shows that the phenomenon of burning engine oil in the vehicle has been more serious, which is called accelerating the burning of engine oil. (Piston or piston ring type trace is the main).

5. In addition to the blue smoke from the exhaust pipe, you can also see pulsating blue smoke coming out of the oil port of the processor. The PCV valve or air-air separator (respirator) is clogged.

6. Generally, during the run-in period, the maximum speed of the new car should not exceed 90 kilometers per hour, and the speed of the engine should not exceed 3 4 of the maximum speed, otherwise it will lead to the phenomenon of burning engine oil, and even lead to long-term excessive consumption of engine oil. In addition, poor oil quality can also lead to insufficient combustion of gasoline, forming carbon deposits, which can lead to the phenomenon of burning engine oil.

7. The car owner should develop good driving habits, and at the same time choose good quality engine oil as much as possible, and the old vehicle search can appropriately choose the oil with slightly larger viscosity to increase the sealing between the piston and the cylinder wall; Check the oil ruler frequently, change the oil and oil filter regularly, and replace the ** oil filter spare parts; Try to choose high-quality engine oil, etc., which can effectively avoid the phenomenon of burning engine oil.

8. "Solution."

Most of the engine oil burning in fuel vehicles is caused by the piston ring being stuck by carbon deposits. Relying on the addition of high-viscosity engine oil to continue life is only an expedient measure to cure the change. The poor power of the engine is due to the fact that the oil participates in the combustion and forms more carbon deposits, which in turn aggravate the degree of oil burning and form a vicious circle.

Excessive carbon deposits will clog the fuel injector, resulting in poor atomization and poor combustion, resulting in higher fuel consumption and lower power. In the long run, it will cause cylinder wall strain, or even cylinder burst, and finally the engine can only be disassembled for overhaul.

Four reasons why you burn engine oil.

A ...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;

IIThe antifreeze replacement cycle is too long or not changed at all;

IIIThe oil change interval is too long;

IVLong-term or often short-distance driving.

The above four points of the vehicle that burns engine oil must be occupied by one or all four points.

How the piston rings are stuck.

The principle of piston ring stagnation should start from 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 residue trace 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 baked dry 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 not good, and soon 4 cylinders are 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.

The solution to burning the oil.

In the habitual thinking of car enthusiasts, they always think that burning engine oil should be overhauled, so that they not only have to bear high maintenance costs, but also bear the unpredictable risks and depreciation losses brought about by the overhaul. Destroy the airtightness and precision of the engine. And after tens of thousands of kilometers, it is possible to burn the engine again, so it is not sustainable to overhaul the engine.

Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of the operation of the auto repair shop, and the owner can operate it himself without removing a screw, and the piston ring is repaired and released during driving, and the effect is remarkable.
