    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.

    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.

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

    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

    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 solving the problem of burning engine oil without dismantling and repair.

    There are two causes of engine oil burning:

    1.Positive wear and tear is a normal phenomenon after a certain number of kilometers of driving. The general vehicle is about 200,000 kilometers, and different vehicles, different people, and different regions (air dust content) have a great impact on the service life of the engine.

    I won't say much about the normal wear and tear of vehicles that exceed a certain service life and kilometers, and the overhaul should be overhauled.

    2.Abnormal wear and tear: The cause of abnormal wear and tear is early wear caused by product quality and improper use.

    If your car burns oil during the warranty period, please contact the manufacturer's four S shop in time to negotiate repair or replacement of the engine. The reasons for the early wear of the engine are: the use of unqualified oil, the failure to change the oil and the oil cleaner within the expiration date, the start of the cold car throttle, the long-term lack of oil to operate, the long-term operation at high temperature, the long-term overload and high speed operation (the engine speed exceeds 4,000 revolutions per minute), the long-term operation in the state of poor air quality (dust content exceeding the standard) and the expiration date without replacing the air cleaner, the oil pump oil pump force is insufficient, the oil pressure is too low, the oil channel is blocked, etc. This will reduce the life of your engine and cause early wear.

    Knowing the reason, friends should avoid the above mistakes in daily driving maintenance, take good care of the vehicle, and prolong the service life of the engine.

    The phenomenon of burning engine oil is as follows: 1. Touch the exhaust pipe with your hands, find that there is a black and wet oil sludge accumulation, and smell the organic oil. 2. Blue smoke comes from the exhaust pipe of the car.

    3. In the case of no oil leakage, the oil is seriously lacking. There are two main reasons why cars burn engine oil. One is the common problem of the model, which is difficult to solve.

    One is caused by excessive wear and aging of the internal components of the engine as the vehicle ages. This situation can be solved by simply replacing excessively worn and aging parts.

    "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, excessive exhaust emissions and other adverse consequences, and in serious cases, the engine is not lubricated enough, so that the engine causes irreparable damage or even scrapped.

    1. Burn engine oil in the cool car: park the vehicle overnight, and observe the exhaust gas discharged when the car is on for the first time in the morning. If the exhaust is a thick blue smoke, it means that the vehicle has burned engine oil.

    If the blue smoke disappears after the car is hot, then this type of engine oil is a cool car burner.

    2. Burn engine oil at any time: Once started, you can see blue smoke, at this time, the engine oil burning situation is quite serious, and there may even be potential safety hazards.

    3. Burning engine oil during rapid acceleration: After the car is heated, whether it is rapid acceleration or idling process, as long as the speed rises rapidly, there will be blue smoke discharged from the exhaust pipe, indicating that the vehicle burns engine oil.

    Although the problem of burning engine oil is very cumbersome to solve, it can be prevented through certain measures in the early stage. Usually use high-quality engine oil, improve the performance of engine oil, clean, lubricate, protect, and control temperature, reduce engine dirt, and avoid wear, which solves the problem of poor fuel and oil quality, and also cleans up carbon deposits.

    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 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.

    The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. Burning engine oil is caused by the following factors, as long as the following problems are solved, burning engine oil can be solved.

    There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the above reasons will aggravate the oil consumption and lead to the burning of engine oil, making the vehicle appear:

    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.

    Nowadays, cars have crankcase ventilation systems (exhaust valves), 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. For some old cars, it is relatively normal to burn engine oil, and we can appropriately choose slightly more viscous engine oil to increase the sealing 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.

    Satisfied, thank you!!

    The main reasons for burning engine oil are:1The gasoline oil is not good and produces carbon deposits, resulting in the piston ring being stuck by carbon deposits, and the piston ring cannot scrape the oil and leave it in the cylinder; 2.

    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 seals and crankshaft seals lead to oil leakage.

    The most obvious phenomenon of burning engine oil is that the exhaust port of the rear of the car will emit blue smoke, and at the same time, the oil consumption will increase significantly, and the oil will have to be replenished in a short time. The phenomenon of burning engine oil in the vehicle will lead to an increase in carbon deposits in the combustion chamber, a decrease in the economy and power of the vehicle, and excessive exhaust emissions.

    It is recommended to use high-quality gasoline in the process of daily use of the car, which can avoid the phenomenon of burning some engine oil, in the normal operation of the car, after the gasoline additives are oxidized, they will generate a gelatinous substance, and after the fuel injector enters the extinguishing chamber and extinguishes, it will constitute carbon deposits 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.

    Hello, there are two kinds of engine oil, one is caused by the valve oil seal, the valve oil seal burns the engine oil, the general cool car is the exhaust pipe blue smoke is heavier, and the heat is lighter. On the other hand, the piston ring burns the engine oil, and the piston ring burns the engine oil, and the exhaust pipe does not emit blue smoke when the car is cool, and the blue smoke from the exhaust pipe is heavier after the hot car. The main phenomenon of burning engine oil is manifested in the exhaust pipe.

    The color of the exhaust gas discharged from the exhaust pipe should be blue, if there is in the idle state, it disappears after increasing the throttle, which should be caused by the failure of the valve seal. If acceleration is noticeable, it should be caused by a faulty piston ring. [Car questions, ask the car master.]

    There are many possible reasons why an engine burns oil, and the most common ones are the following:

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