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(guò)氣缸壁進(jìn)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(guò)大。

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

2、活塞環(huán)對(duì)口。

2. Match the piston rings.

3、活塞環(huán)彈力不夠。

3. The piston ring is not elastic enough.

4、活塞環(huán)磨損，除了工作面磨損還有和環(huán)槽的側(cè)隙過(guò)大。

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

5、活塞環(huán)失效，尤其是油環(huán)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(jī)油，減少缸壁磨損，這種正常的機(jī)油消耗非常少，可以忽略不計(jì)。

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(guò)氣門進(jìn)入燃燒室的機(jī)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(guò)氣門導(dǎo)管進(jìn)入燃燒室，主要原因是氣門油封老化、導(dǎo)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(qiáng)制通風(fēng)閥故障造成進(jìn)氣管真空把機(jī)油抽入進(jìn)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(zhuǎn)軸密封失效，機(jī)油漏到進(jìn)氣道。

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

氣門導(dǎo)管滲漏機(jī)油主要是氣門油封老化，或者潤(rùn)滑不好，造成的氣門導(dǎo)管異常磨損。解決方法就是更換氣門油封或者氣門導(dǎo)管。預(yù)防的方法同樣是選用優(yōu)良的機(jī)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(jī)油油主要是渦輪增壓器的轉(zhuǎn)軸出現(xiàn)磨損，預(yù)防的方法是使用優(yōu)良的全合成機(jī)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(fēng)系統(tǒng)失效造成真空直接把油氣吸入進(jìn)氣道參與燃燒。解決的方法只有更換曲軸箱通風(fēng)系統(tǒng)。

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(guò)以上分析可以看出發(fā)動(dòng)機(jī)油、空氣濾芯的性能是至關(guān)重要的，至于材質(zhì)、設(shè)計(jì)、零件失效就不是我們能夠控制的了，只能亡羊補(bǔ)牢，及時(shí)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.
