机油污染和变质的原因
Causes of oil contamination and deterioration
机油存放污染和变质主要是机油与空气中的水分、氧和杂质接触导致的,所以开封后的机油一定要密封保存。
The oil storage pollution and deterioration are mainly caused by the contact between the oil and the water, oxygen and impurities in the air. Therefore, the oil after opening must be sealed and stored.
水分
water content
正常情况下机油中的含水量在0.03%以下,当含水量超过0.1%时,机油中的添加剂(抗氧化剂、清净分散剂等)就会失效,加速机油的氧化过程。而机油氧化生成的有机酸及发动机排出废气中的酸性氧化物与水发生反应,又生成无机酸。这些酸性物质增加对发动机的腐蚀。
Under normal conditions, the water content in the engine oil is below 0.03%. When the water content exceeds 0.1%, the additives (antioxidants, detergents, dispersants, etc.) in the engine oil will become invalid, accelerating the oxidation process of the engine oil. The organic acids generated by the oxidation of engine oil and the acid oxides in the exhaust gas from the engine react with water to generate inorganic acids. These acids increase the corrosion of the engine.
因此当机油中含有较多的水时,机油润滑性会变差,粘度下降,轻则导致机油过早变质和机件生锈;重则引起发动机抱轴、烧瓦等严重机械事故。
Therefore, when there is more water in the engine oil, the lubricating property of the engine oil will become worse, and the viscosity will drop, which may lead to premature deterioration of the engine oil and rusting of the parts; In serious cases, it may cause serious mechanical accidents such as engine shaft seizure and bearing burning.
氧气
oxygen
机油由基础油和添加剂组成,虽然基础油一般都比较稳定,但是机油中其重要作用的添加剂稳定性要弱很多,遇到空气中的氧很容易产生化学反应,特别是在有阳光照射的环境下,导致添加剂变质,大幅降低了机油的抗氧化性、清洁性等特性。
The engine oil is composed of base oil and additives. Although the base oil is generally stable, the stability of the additives that play an important role in the engine oil is much weaker. When encountering the oxygen in the air, it is easy to produce chemical reactions, especially in the environment with sunlight, which leads to the deterioration of the additives, greatly reducing the anti-oxidation, cleanliness and other characteristics of the engine oil.
杂质
impurity
杂质主要影响机油的清洁度,机油中混入杂质后会影响机油的润滑效果,甚至导致发动机异常磨损,进而影响其密封性能。
Impurities mainly affect the cleanliness of the engine oil. Impurities mixed in the engine oil will affect the lubricating effect of the engine oil, even lead to abnormal wear of the engine, thus affecting its sealing performance.
开封后机油的保存方法
Storage method of oil after opening
知道了机油污染和变质的原因后,下面就对症下药,解析下开封后机油的保存方法。
After knowing the cause of oil pollution and deterioration, we will take the right medicine to solve the problem and analyze the preservation method of oil after opening.
开封后立即封存,在4S店或者维修厂保养完成后,应立即将机油瓶盖 拧上。需要注意的是,由于原厂的锡纸膜已经破坏,剩下的盖垫隔绝作用有限,这个时候可以使用一层干净塑料薄膜套在瓶口,为了避免破损对折几次后套上,然后再拧上瓶盖,这样密封效果更好一些。有条件的也可以在瓶口盖子处滴蜡密封。
Seal it immediately after unsealing, and screw on the oil bottle cap immediately after maintenance in the 4S shop or repair shop. It should be noted that since the original tin foil film has been damaged, the remaining cap pads have limited insulating effect. At this time, a layer of clean plastic film can be used to cover the mouth of the bottle. In order to avoid damage, fold it in half several times, cover it, and then screw on the cap, so that the sealing effect is better. If conditions permit, wax can also be dropped at the bottle mouth cap for sealing.
机油瓶密封后需要将其存放在干燥凉爽的地方,并确保太阳光不会照射到,避免里面的机油发生氧化反应。
After the oil bottle is sealed, it needs to be stored in a dry and cool place, and ensure that the sun will not shine on it to avoid oxidation reaction of the oil inside.
在下次保养取出存放已久的机油后,在向发动机中加入的过程中不要将其完全倒入,应保留一部分,一般来说长时间存放机油瓶底多少会有微量的水分,加入到发动机中会影响其性能发挥甚至产生不良的影响。
After the oil that has been stored for a long time is taken out for the next maintenance, do not pour it into the engine completely, but keep some of it. Generally speaking, there will be a little water at the bottom of the oil bottle that has been stored for a long time, and adding it into the engine will affect its performance or even cause adverse effects.
一般来说使用后的机油密封存放周期按照其类型有所差异:矿物油存储6个月问题不大;半合成可以存放9个月;全合成可以存放12个月甚至更长时间。无论是哪一类型的机油,这段时间都足以支撑到汽车下次保养。
Generally speaking, the oil seal storage period after use varies according to its type: mineral oil storage for 6 months is not a problem; Semi synthetic products can be stored for 9 months; It can be stored for 12 months or even longer. No matter what type of engine oil, this period of time is enough to support the next maintenance of the car.
