The way to control the burning of engine oil is to heat the cleaning agent, and at the same time, the piston moves around slightly, so that the cleaning agent can penetrate into the piston ring to clean. The reason for burning engine oil is: when the engine works for a certain period of time, the piston ring diameter width will decrease, the elastic force will weaken, and the opening clearance will become larger, which will affect the engine oil addition in the clearance. When the piston goes up, the engine oil will be hung into the combustion chamber and burned together with the mixture, so the phenomenon of burning engine oil will appear. The phenomenon of vehicle burning engine oil will damage the oxygen sensor of the vehicle too quickly, affect the bad consequences such as carbon accumulation in the combustion chamber, unstable idle speed, weak acceleration, increased fuel consumption, excessive exhaust emissions, seriously affect the insufficient lubrication of the engine, make the engine cause damage that is difficult to repair or even scrap, and cause a substantial increase in repair costs and even potential accidents.

通過氣缸壁進入燃燒室，主要的因素如下：

The main factors for entering the combustion chamber through the cylinder wall are as follows:

1、活塞與缸筒的間隙過大。

1. The clearance between piston and cylinder barrel is too large.

2、活塞環對口。

2. Match the piston rings.

3、活塞環彈力不夠。

3. The piston ring is not elastic enough.

4、活塞環磨損，除了工作面磨損還有和環槽的側隙過大。

4. Piston ring wear, in addition to working face wear and ring groove side clearance is too large.

5、活塞環失效，尤其是油環的失效影響較大。

5. The failure of piston ring, especially the failure of oil ring, has great influence.

6、氣缸壁本身就加工出一定粗糙度的交叉紋路的珩磨紋，目的就是留存一定量的機油，減少缸壁磨損，這種正常的機油消耗非常少，可以忽略不計。

6. The cylinder wall itself processes a certain roughness of cross grain honing lines, the purpose is to retain a certain amount of oil, reduce the cylinder wall wear, this normal oil consumption is very small, can be ignored.

通過氣門進入燃燒室的機油主要有如下途徑：

The main ways of oil entering the combustion chamber through the valve are as follows:

1、通過氣門導管進入燃燒室，主要原因是氣門油封老化、導管磨損。

1. The main reasons for entering combustion chamber through valve guide are aging of valve oil seal and wear of guide.

2、曲軸箱強制通風閥故障造成進氣管真空把機油抽入進氣道。

2. The failure of the positive crankcase ventilation valve results in a vacuum in the intake pipe, which draws oil into the intake port.

3、渦輪增壓器轉軸密封失效，機油漏到進氣道。

3. Turbocharger shaft seal failure, oil leakage to the inlet port.

氣門導管滲漏機油主要是氣門油封老化，或者潤滑不好，造成的氣門導管異常磨損。解決方法就是更換氣門油封或者氣門導管。預防的方法同樣是選用優良的機油。

Oil leakage of valve guide is mainly caused by aging of valve oil seal or poor lubrication, resulting in abnormal wear of valve guide. The solution is to replace the valve seal or valve guide. The prevention method is also to choose excellent engine oil.

渦輪增壓器漏機油油主要是渦輪增壓器的轉軸出現磨損，預防的方法是使用優良的全合成機油。

Turbocharger oil leakage is mainly due to the wear of the turbocharger shaft. The best way to prevent it is to use excellent synthetic oil.

曲軸箱通風系統失效造成真空直接把油氣吸入進氣道參與燃燒。解決的方法只有更換曲軸箱通風系統。

The failure of the crankcase ventilation system results in the vacuum directly sucking oil and gas into the intake port to participate in combustion. The only solution is to replace the crankcase ventilation system.

通過以上分析可以看出發動機油、空氣濾芯的性能是至關重要的，至于材質、設計、零件失效就不是我們能夠控制的了，只能亡羊補牢，及時更換故障件。

From the above analysis, we can see that the performance of engine oil and air filter element is very important. As for the material, design and failure of parts, we can not control them. We can only mend them quickly and replace them in time.
