How do you know if the engine of the car is burning oil?

Identification method of burning engine oil:

1. Cool car burning engine oil: When you get on the car for the first time every morning, there will be a relatively thick blue smoke exhaust from the rear exhaust pipe. After a while, the blue smoke disappears, and there is generally no similar situation on the day.

2. Burn engine oil when accelerating: When the driver slams on the accelerator or steps on the accelerator when the vehicle is moving, a large amount of blue smoke is discharged from the exhaust pipe, and when the driver slams the accelerator when the vehicle is driving, the driver can see the blue smoke from the reflector on the exhaust pipe side.

3. Fill the vehicle with the phenomenon of "burning engine oil" with engine oil, let the owner go to the maintenance station to weigh the oil filter after driving 1000 kilometers, and then fill up the engine oil, and then let the owner drive 1000 kilometers. Repeated 3 times, to obtain an average value, after the run-in period of normal oil consumption can generally reach 1000 kilometers liters, if the standard is exceeded, there is a situation of burning oil.

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.

1.Whether there is blue smoke coming from the exhaust pipe: When the car starts in the morning, check if the exhaust pipe of the car is emitting blue smoke.

If found (check the transaction price|Matching|Preferential policy) blue smoke from the exhaust pipe, indicating that the car has the phenomenon of burning engine oil. When you make a good judgment through this method, you can find two people. Since the time it takes for a car exhaust pipe to emit blue smoke is quite short, it is difficult to detect it immediately if the car is started.

2.Look inside the exhaust pipe:

Judging the oil combustion phenomenon through the exhaust pipe is a fairly simple method of eliminating the bridge. After the car is turned off, observe the inside of the exhaust pipe. If there is a little black sediment on the inside of the exhaust pipe, which is a little sticky, it means that the engine performance is poor during the driving of the car, and there is a little oil mixed in, and there is a phenomenon of burning engine oil.

Whether the oil burns seriously can be judged by the amount of black sediment.

3.Is there carbon deposit in the spark plug:

The carbon deposits of spark plugs during normal use are quite delicate and the amount is quite small. If the car burns engine oil, the carbon deposition of the spark plug will be quite obvious. The method of judging the spark plug burning engine oil is a little more troublesome than the previous year. You can go to a professional 4S shop or repair shop for **.

Attached: Reasons for burning engine oil:

1.Fuel quality issues:

Because the quality of automobile oil is not uniform, there may be a wide range of carbon deposits during combustion. Carbon deposits in cars are the cause of many engine failures. Therefore, when refueling the car, we must ensure the quality of the car oil, prevent adding a little oil with bad oil quality, and try to refuel at a regular gas station.

2.Corrosion and deterioration of valve seals:

After long-term use of the car, there will be aging of the oil seal and poor sealing. Valve seals are the most susceptible part of an engine to deterioration. Pay attention to the valve oil seal when maintaining the car, and deal with it immediately if there is any abnormality to prevent the aging of the valve oil seal from affecting the combustion of the automobile oil.

The most intuitive performance, the exhaust pipe emits blue smoke.

Three types of oil-burning phenomena are classified.

1. 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 again on the same day, but this phenomenon occurs again on the second and third mornings, which indicates that the vehicle has burned engine oil, which is called burning engine oil in a cool car.

2. When the vehicle is driving or on the spot, the exhaust pipe emits a large amount of blue smoke when the driver slams on the accelerator, which indicates that the phenomenon of the vehicle burning engine oil has been more serious, which is called accelerating the burning of engine oil.

3. In addition to the blue smoke coming out of the exhaust pipe, you can also see pulsating blue smoke coming out of the oil port of the processor. In this case, the damage to the engine is already severe.

Analysis and solutions.

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, rising fuel consumption, excessive exhaust emissions and other adverse consequences.

There is no warning of burning engine oil, and it is said that it will burn, and the illness will come like a mountain. Moreover, the new car has not burned engine oil for tens of thousands of kilometers, and once it starts to burn engine oil, it will become very serious in half a year and half a year. However, it has happened that the engine lives by oil and burns the engine seriously, so it is recommended to check it first, and don't be in a hurry to deal with the engine problem blindly.

Burning engine oil will lead to shaking, weakness, high fuel consumption and other possible phenomena, these are caused by burning engine oil, don't be in a hurry to deal with small phenomena, first deal with the problem of burning engine oil on the main line.

If it is delayed, it will cause the oil to participate in more and more combustion, and finally pull the cylinder, because the oil participates in the combustion, there are more oil components in the mixture, and the load of the three-way catalysis is too large, and the three-way catalysis will be replaced in advance, and the three-way catalysis is very expensive, which will lead to a sharp increase in costs. The result of relying on oil to continue life is that the cylinder must be dismantled, the engine must be dismantled, the engine must be overhauled, and the valuable three-way catalysis must be replaced in advance.

Therefore, starting from the oil circuit to solve the problem is the way to eradicate the root. But not casually, the oil circuit cleaner does not have the function of releasing the piston ring, let alone using something like PEA, and do not clean the carbon deposits in the cylinder separately. If you want to use a PNF-type cleaner, you can release the piston ring.

Prevention of engine oil burning and solutions.

Do you have to overhaul the engine oil?

When the vehicle is driving or on the spot, the exhaust pipe emits a large amount of blue smoke when the driver slams on the accelerator, which indicates that the phenomenon of burning engine oil in the vehicle has been more serious, and this phenomenon is called accelerating the burning of engine oil.

In general, the performance of burning engine oil is the exhaust pipe when driving to remove blue exhaust gas, which means that too much oil enters the combustion chamber to participate in combustion. Under normal circumstances, the engine will also burn off some of the oil from the cylinder block, piston and valve lubrication, but only in small amounts. This refers to the phenomenon of burning engine oil beyond the normal range.

into the combustion chamber of the both.
