JAC Ruifeng business vehicle 2 8 how 130,000 kilometers will burn engine oil

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.

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem. In the past, the problem of burning engine oil could only be solved by dismantling and repairing, but now there is a plan to solve the problem of burning engine oil without dismantling and repairing, which can be understood by taking a look.

It is inevitable that the oil that plays a lubricating role between the piston and the cylinder wall in the engine will participate in the combustion, as long as it does not exceed one liter within 5,000 kilometers, it is normal oil consumption, and vice versa. The lack of engine oil will cause the engine to heat up badly, the car will shake abnormally, the water temperature will be high, the valve will sound, and in serious cases, it will even strain the cylinder wall or burst the cylinder.

Burning engine oil is basically caused by piston ring stagnation. As long as there is no serious strain on the cylinder wall, it does not need to be overhauled. Changing the maintenance of high-viscosity engine oil is only an expedient measure to treat the symptoms rather than the root cause, and it will do more harm than good.

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 there is a possibility that the engine oil will burn again after tens of thousands of kilometers, so overhauling the engine is not sustainable.

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 burning engine oil and having to go to the auto repair shop for overhaul, without removing a screw, repairing and releasing the piston ring stuck engine oil while driving, with remarkable results.

JAC Refine will not burn engine oil in the early stage, and the oil that will burn engine oil in the later stage will be consumed to a certain extent. Excessive consumption is the problem of burning engine oil. There are several factors in burning oil, as long as Xie Xiang ordered the emperor to solve the following problems, burning oil can be solved.

There are many factors that affect oil combustion, such as: fuel quality, road conditions, driving habits, maintenance habits, etc. The above reasons will exacerbate fuel consumption, lead to fuel burning, and cause the appearance of the vehicle

1.Carbon deposits occur in the combustion chamber, causing the air ring of the piston ring to jam, resulting in poor sealing. Jinyan 2

Oil sludge is generated in the lubrication system, which clogs 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 aged, and the sealing performance fails. If the oil is burned by the wind, poor cylinder sealing is the main reason for burning the oil.

The poor sealing performance of the cylinder is mainly due to the excessive gap between the piston and the cylinder wall, the improper installation of the piston ring or poor sealing performance, and the oil on the cylinder wall enters the combustion chamber, resulting in oil combustion. In addition, poor sealing of valve seals, damaged crankcase vents or clogged crankcase vents can cause excessive pressure in the crankcase, which can lead to oil entering the cylinder with crankcase gases and participating in combustion. Cold-boiled engine oil:

Before the temperature of the car was fully warmed up, a lot of blue smoke came out of the engine exhaust pipe, but after the warm-up it was normal. This phenomenon is caused by the aging of the valve seals. As the temperature of the valve seal decreases, the rubber valve seal becomes stiff and cannot be fully sealed.

This phenomenon occurs when the oil leaks from the valve into the combustion chamber for combustion. If it is determined that the hot car burns the engine oil, and it is not serious (for safety reasons, the cylinder pressure test can be carried out first), the oil pan can be directly removed, the piston can be directly removed, and the piston ring can be replaced. In this case, the cost and time are similar to the first solution.

Qinqin is happy to serve you: JAC Rui fan oil increase is 1, the oil is mixed with gasoline or water. In the process of driving, due to the poor sealing of the piston or cylinder, the mixture gas enters the crankcase, and when the temperature drops, the gas will liquefy into liquid, and flow back to the oil pan to increase the oil oil, which is mixed with water in the oil.

When the fuel is not burned sufficiently in the cylinder, it flows back into the oil pan, which also causes an increase in the amount of oil, which is mixed with gasoline. 2. Engine component mechanism. The increase in oil volume is related to the engine component mechanism, such as insufficient pressure of the cylinder and poor sealing of the cylinder, which will reduce the power of the engine and make it difficult to start.

There are also poor injectors that cause excessive oil dripping or excessive fuel injection, but these two simple cases must be monitored by the maintenance master to confirm the cause and repair. 3. Temperature conditions. In the process of cold start, a thicker mixture is required, so the fuel injector will also inject more gasoline, which also makes the remaining gasoline flow back into the oil pan, and the reason for the increase in oil is generally that the oil injection is too much.

Solution: In a low-temperature environment, carry out more behaviors such as hot car and high-speed running, so that the engine can reach sufficient temperature conditions, and the gasoline or water mixed in the engine oil can be evaporated. However, if the phenomenon of oil increase has not been improved, it is best to go to a 4S shop or maintenance shop for an in-depth professional inspection to find the source of the fault and solve the problem of oil increase.

Hello, what causes burning 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, thank you.
