As one of the items must be done in a minor repair, the oil filter often needs to be replaced. However, some owners may think that the function of the oil filter is to filter impurities in the oil. Why should I change the oil? In fact, it must be the reason why the oil has been used for a long time and lost its performance. There are other reasons. Let's explain the working process of the lubrication system from Jinan automatic gearbox maintenance manufacturer.

　　這就是機(jī)油過濾器經(jīng)常被更換的原因

　　This is why the oil filter is often replaced

　　機(jī)油，也叫機(jī)油，通常儲存在發(fā)動機(jī)底部的油底殼里。當(dāng)發(fā)動機(jī)運(yùn)行時，一部分發(fā)動機(jī)功率將由發(fā)動機(jī)油泵把油抽上來，然后泵的壓力將它送到發(fā)動機(jī)的各個部位進(jìn)行潤滑。潤滑過的油沿井壁滴入油底殼，然后泵入潤滑部件。經(jīng)過反復(fù)潤滑，磨損的金屬屑或粉塵會與機(jī)油混合，只會加速滑動面的磨損。因此，必須在油路上安裝機(jī)油濾清器，以便隨時對機(jī)油進(jìn)行過濾。即使這樣，油在很長一段時間后會變臟，所以你必須在行駛一段距離后更換機(jī)油。這種油在潤滑時會產(chǎn)生冷卻效果。

　　Oil, also called engine oil, is usually stored in the oil pan at the bottom of the engine. When the engine is running, part of the engine power will be pumped up by the engine oil pump, and then the pressure of the pump will send it to all parts of the engine for lubrication. The lubricated oil drips into the oil pan along the well wall, and then pumps into the lubricating parts. After repeated lubrication, the worn metal chips or dust will mix with the engine oil, which will only accelerate the wear of the sliding surface. Therefore, the oil filter must be installed on the oil circuit in order to filter the oil at any time. Even so, the oil gets dirty after a long time, so you have to change the oil after a long distance. This oil has a cooling effect when lubricated.

　　濟(jì)南自動變速箱維修廠家解釋說，過濾器只能過濾與機(jī)油混合的金屬碎片、灰塵(空氣中的灰塵)。所以你不僅要更換過濾器，還要根據(jù)維護(hù)手冊更換機(jī)油。

　　Jinan automatic gearbox maintenance manufacturer explained that the filter can only filter the metal debris and dust (dust in the air) mixed with the engine oil. So you should not only change the filter, but also change the oil according to the maintenance manual.
