沃爾沃汽車發(fā)動(dòng)機(jī)重要的油液就是機(jī)油，一般全合成的機(jī)油壽命在一萬，但是即使是放著不用，只要接觸空氣了，機(jī)油就會(huì)氧化并逐漸變質(zhì)，更何況發(fā)動(dòng)機(jī)工作時(shí)會(huì)面臨各種各樣復(fù)雜的工況。那如何延緩機(jī)油劣化變質(zhì)，保證使用性能？
濟(jì)南沃爾沃汽車專修廠家為你解答。
The important oil of Volvo Cars' engines is engine oil. Generally, the life of fully synthetic engine oil is 10000 km. However, even if it is left unused, as long as it contacts with air, the engine oil will be oxidized and gradually deteriorate, and the engine will face various complex working conditions. How to delay the deterioration of engine oil and ensure its performance? The specialized manufacturer of Volvo Cars in Jinan will answer for you.
一.定期更換機(jī)油濾芯
1、 Replace the oil filter element regularly
機(jī)油濾芯的主要作用是過濾機(jī)油中的雜質(zhì)、污垢，為發(fā)動(dòng)機(jī)提供清潔的潤滑油，保持油路暢通。但是機(jī)油濾芯也有使用期限，長(zhǎng)期不換會(huì)影響過濾性能，當(dāng)雜質(zhì)過多而無法得到有效過濾時(shí)，機(jī)油會(huì)加速劣化變質(zhì)，性能大打折扣。
The main function of the engine oil filter element is to filter impurities and dirt in the engine oil, provide clean lubricating oil for the engine, and keep the oil path smooth. However, the engine oil filter element also has a service life. If it is not replaced for a long time, the filtering performance will be affected. When there are too many impurities and it cannot be filtered effectively, the engine oil will deteriorate rapidly and the performance will be greatly reduced.
二.定期清潔潤滑系統(tǒng)
2、 Clean the lubrication system regularly
無論是重力放油還是抽油機(jī)抽油，都無法完全將舊機(jī)油放干凈，油底殼中一定會(huì)有油泥和氧化了的舊機(jī)油殘留。殘留的舊機(jī)油又會(huì)污染新機(jī)油，加速新機(jī)油劣化變質(zhì)，縮短新機(jī)油的使用壽命。
Neither gravity drainage nor pumping unit can completely drain the old engine oil, and there must be sludge and oxidized old engine oil residues in the oil pan. The residual old engine oil will pollute the new engine oil, accelerate the deterioration of the new engine oil, and shorten the service life of the new engine oil.
因此，每隔一段時(shí)間需定期清潔潤滑系統(tǒng)，去除殘留的沉積物和舊機(jī)油。
Therefore, the lubrication system should be cleaned regularly at regular intervals to remove residual deposits and old oil.
可以在換油前將發(fā)動(dòng)機(jī)清潔劑加入舊機(jī)油中，怠速10-15分鐘后放出即可有效溶解掉發(fā)動(dòng)機(jī)內(nèi)部油泥等沉積物，使舊機(jī)油排出更好，減少對(duì)新機(jī)油的污染。
The engine cleaner can be added to the old engine oil before changing the oil. After idling for 10-15 minutes, it can effectively dissolve the sludge and other deposits inside the engine, so that the old engine oil can be discharged better and the pollution to the new engine oil can be reduced.
三.選擇高品質(zhì)機(jī)油
3、 Select high quality oil
三個(gè)指標(biāo)直接決定機(jī)油的劣化變質(zhì)速度：清潔分散性、抗氧化性、總堿值。
Three indexes directly determine the deterioration rate of engine oil: clean dispersibility, oxidation resistance and TBN.
清潔分散性：機(jī)油在高溫高壓狀態(tài)下會(huì)生成各種氧化產(chǎn)物，這些氧化產(chǎn)物會(huì)與零部件磨損產(chǎn)生的金屬粉末混合在一起，變成沉積物。沉積物量少時(shí)會(huì)在機(jī)油中懸浮，量大時(shí)就會(huì)從機(jī)油中析出，堵塞濾清器和油孔、阻礙機(jī)油的正常流動(dòng)。如果你選購的機(jī)油清潔分散性夠強(qiáng)，就能主動(dòng)溶解、分散沉積物，避免堵塞，在整個(gè)使用周期內(nèi)保證機(jī)油的正常性能。
Cleanliness and dispersibility: under high temperature and pressure, the engine oil will generate various oxidation products, which will be mixed with the metal powder produced by parts wear and become sediment. When the amount of sediment is small, it will be suspended in the engine oil. When the amount is large, it will be separated from the engine oil, blocking the filter and oil hole, and blocking the normal flow of engine oil. If the oil you choose is clean and dispersive enough, it can actively dissolve and disperse the sediment to avoid clogging and ensure the normal performance of the oil throughout the service life.
抗氧化性：發(fā)動(dòng)機(jī)內(nèi)部的高溫會(huì)使機(jī)油迅速氧化，氧化后的機(jī)油各項(xiàng)性能都會(huì)下降，氧化到一定程度后即需更換。而抗氧化性能更強(qiáng)的機(jī)油可以有效抑制機(jī)油的氧化進(jìn)程，實(shí)現(xiàn)更長(zhǎng)的換油周期。
Oxidation resistance: The high temperature inside the engine will rapidly oxidize the engine oil, and the performance of the oxidized engine oil will decline. The engine oil needs to be replaced when it is oxidized to a certain extent. The engine oil with stronger oxidation resistance can effectively inhibit the oxidation process of engine oil and achieve a longer oil change cycle.
總堿值：燃油燃燒時(shí)產(chǎn)生的酸性物質(zhì)和氣體會(huì)融入機(jī)油，導(dǎo)致機(jī)油酸化，使機(jī)油的各項(xiàng)性能迅速衰減，加速機(jī)油劣化變質(zhì)。我國燃油中的含硫量很高，機(jī)油酸化速度更快，因此選擇總堿值更高的機(jī)油可以更好地中和機(jī)油中的酸性物質(zhì)，延緩機(jī)油酸化變質(zhì)的速度。
TBN: Acids and gases generated during fuel combustion will melt into the engine oil, causing the engine oil to be acidified, rapidly reducing the performance of the engine oil, and accelerating the deterioration of the engine oil. In our country, the sulfur content in the fuel is very high, and the speed of oil acidification is faster. Therefore, selecting the oil with higher TBN can better neutralize the acid substances in the oil, and delay the speed of oil acidification.
此外發(fā)動(dòng)機(jī)頻繁啟停、走走停停，機(jī)油也會(huì)因?yàn)橛蜏靥投a(chǎn)生較多的低溫油泥沉積，促進(jìn)機(jī)油的劣化變質(zhì)。長(zhǎng)此以往，機(jī)油固有的油膜特性會(huì)逐漸失效，機(jī)油潤滑性能變差甚會(huì)完全喪失潤滑功能。所以做好相關(guān)的工作非常關(guān)鍵，您有需求就來我們網(wǎng)站

In addition, if the engine starts and stops frequently, the engine oil will also produce more low-temperature sludge deposits due to the low oil temperature, which will promote the deterioration of the engine oil. In the long run, the inherent oil film characteristics of the engine oil will gradually become invalid, and the lubricating performance of the engine oil will become worse or even completely lose its lubricating function. So it is very important to do a good job in related work. Come to our website if you need http://www.lysjkw.com Ask and understand!
