    汽车出现烧机油与这些情况有关!
    2021-10-11 16:22:30

    由于国内燃油品质与国际标准不同步,使得发动机行驶过程中,极易在燃烧室内形成大量积碳,积碳则是引发烧机油等发动机各类问题的重要原因。

    Because the domestic fuel quality is not synchronized with the international standards, it is very easy to form a large amount of carbon deposit in the combustion chamber during engine driving. Carbon deposit is an important reason for various engine problems such as engine oil.

    积碳会沉积在活塞的凹槽内,导致活塞环粘在一起,这样导致活塞环卡死无法完全密封,机油会因此进入燃烧室烧掉,而 “黏住”的活塞环大大降低了刮油密封能力,未被刮掉的机油也会被烧掉。

    Carbon deposits will deposit in the groove of the piston, causing the piston rings to stick together, which will cause the piston rings to get stuck and cannot be completely sealed. Therefore, the oil will enter the combustion chamber and burn off. The "stuck" piston ring greatly reduces the oil scraping and sealing ability, and the oil that has not been scraped off will also be burned off.

    长期形成的油泥得不到清理,也会堵塞活塞环上的回油孔,导致机油无法正常回流,使机油留在燃烧室里燃烧了。

    If the oil sludge formed for a long time is not cleaned, it will also block the oil return hole on the piston ring, resulting in the failure of normal oil return, leaving the oil in the combustion chamber for combustion.

    积碳又会加剧活塞与气缸壁之间的磨损,造成间隙过大,导致机油进入燃烧室烧掉。

    Carbon deposition will aggravate the wear between the piston and the cylinder wall, resulting in excessive clearance, resulting in oil entering the combustion chamber and burning.

    气门油封腐蚀老化,造成密封不严,机油会因此漏入燃烧室烧掉。气门油封可以说是发动机里最容易老化的易损件,基本上行驶了10万公里以上的汽车,都有此问题。

    The valve oil seal is corroded and aged, resulting in loose sealing, so the oil will leak into the combustion chamber and burn. Valve oil seal can be said to be the most easily aging vulnerable part in the engine. Basically, cars that have driven more than 100000 kilometers have this problem.

    前后曲轴油封老化,前后曲轴油封与油大面积且持续接触,油的杂质和发动机内持续温度变化使其密封效果逐渐减弱,一是会造成渗油或漏油,造成机油消耗增加;二是机油蒸汽也会在高压的作用下在密封薄弱处溢出,造成机油损耗。

    The front and rear crankshaft oil seals are aging. The front and rear crankshaft oil seals are in large area and continuous contact with the oil. The oil impurities and the continuous temperature change in the engine gradually weaken the sealing effect. First, it will cause oil leakage or oil leakage, resulting in increased oil consumption; Second, the oil vapor will also overflow at the weak seal under the action of high pressure, resulting in oil loss.

    涡轮增压器故障,一是因密封环损害等原因造成漏油,机油通过发动机进气管进入燃烧室被烧掉;二是机油品质问题导致润滑不良,轴承磨损,造成机油消耗量增大。

    Turbocharger failure: first, oil leakage is caused by seal ring damage and other reasons, and the oil enters the combustion chamber through the engine inlet pipe and is burned; Second, the problem of oil quality leads to poor lubrication and bearing wear, resulting in increased oil consumption.

    机油中存在高比例的燃油,燃油供给系统工作不良、燃油雾化不好,会使燃油或大量的过浓燃油混合气窜入曲轴箱与机油混合,将机油稀释,造成机油消耗过大。

    There is a high proportion of fuel in the engine oil. The poor operation of the fuel supply system and poor fuel atomization will make the fuel or a large amount of too rich fuel mixture rush into the crankcase to mix with the engine oil, dilute the engine oil and cause excessive engine oil consumption.
