Judge the reason and overhaul of car engine oil burning

The reasons for engine oil burning are as follows: Poor valve sealing: the valve is to prevent oil leakage to In the combustion chamber, but as the service life increases, there will be wear and aging, resulting in poor valve sealing, so that the oil is easy to enter the combustion chamber.

The color of automobile exhaust can also judge the cause of oil burning: the internal piston ring failure of the engine is not sealed, the oil flows into the cylinder to burn, and oil burning fault will occur. If the gasket between the engine cylinder head and the cylinder block is deformed or damaged, the oil in the oil line flows into the cylinder, and oil burning failure will also occur.

Abnormal wear: The causes of abnormal wear are product quality and early wear caused by improper use.If your car burns oil during the warranty period, please contact the manufacturer's four S store in time to negotiate maintenance or replace the engine.

First of all, you need to confirm the reason for burning the engine oil. The main reasons for burning the engine oil are two aspects. One is that there is a problem with the accessories, such as the exhaust gas valve, the valve oil seal, the cylinder in the cylinder, and the cylinder pressure is insufficient. Second, the oil line is not cleaned for a long time, the antifreeze is not replaced in time, the oil use cycle is too long, and the piston ring is stuck. The more common situation is that the piston ring is stuck.

The reason for burning engine oil The engine oil itself consumes a certain amount, and excessive consumption means that there is a problem of burning engine oil.

Therefore, the link of checking the reason for burning oil in the car cannot be ignored after playing.

What is the phenomenon of burning engine oil

1. There are four types of burning engine oil: blue smoke when the cold car starts, blue smoke when accelerating, the inner wall of the exhaust pipe is very black, and the oil consumption is too fast. Blue smoke emots when the cold car starts.

2. The main reason is that the lubricating oil film breaks when the engine is running at high speed, resulting in oil burning phenomenon. I hope everyone can maintain economic speed in daily driving; Third, the vehicle emits blue smoke during acceleration. Especially if you find that blue smoke begins to come out of the exhaust pipe when you step on the accelerator hard, it means that there is oil burning in the car.

3. There are three phenomena that the car burns engine oil. One is that the exhaust pipe highlights blue smoke when the cold car starts, the other is that a large amount of blue smoke comes out of the exhaust pipe when the car accelerates, and the other is that the driving computer shows that the oil consumption is too fast.

4. The serious result of burning engine oil will be insufficient lubrication of the engine, resulting in irreparable damage or scrapping of the engine. Burning oil seems to be a small matter, and when it is serious, it will cause great safety hazards, so you should learn some common sense of discrimination.

How to judge the car burning engine oil? In addition to blue smoke

and when the oil burns in the engine, the gas produced appears blue. If your car's power is significantly reduced and the exhaust gas produces a large amount of blue smoke, then the oil is burning.When the cold car starts, if a large amount of blue smoke comes out of the exhaust pipe, it also means that the car has burned the oil.

The exhaust pipe is very dirty, with oil stains and black oil stains. One is to remember where the existing position is and how much to watch after running for a while.

Blue smoke comes from acceleration. When the car is driving, when you increase the accelerator and find a large amount of blue smoke coming out of the exhaust pipe, it means that the engine has a phenomenon of burning oil.

View: The main manifestation of burning engine oil is that the tail discharges blue exhaust gas when driving, which means that too much engine oil enters the combustion chamber to participate in combustion. The specific operations are as follows: (1) After the cold car starts in the morning, check whether the exhaust pipe will have blue smoke.

Performance 1: Blue exhaust gas appears in the exhaust pipe when the cold car starts in the morning, and disappears after a period of operation.

How to judge; oil seal aging. In this kind of situation, there will be black smoke and blue smoke when the cold car starts, and there is no smoke in the hot car. Because the oil seal is sealed and strengthened after the high temperature, only the cold car will appear. For this kind of phenomenon, the oil seal can be replaced or the oil seal can be repaired.
