大保養的內容：小保養的項目，都是被大保養所涵蓋的；意思就是說：每次大保養時，一般都會執行小保養所含的所有項目。而大保養的項目依照不同廠家的不同車輛設計，也會有細部的不同區分。但大致上，它還會有一個簡略的共通性。大保養進行的內容為更換機油和機油濾清器、空氣濾清器、汽油濾清器等的常規保養。
Big Maintenance Content: Small Maintenance Project is covered by Big Maintenance; that is to say, every Big Maintenance will generally carry out all the items contained in Small Maintenance. Large maintenance projects are designed according to the different vehicle designs of different manufacturers, and there will be different details. But in general, it will have a brief commonality. The major maintenance is to replace oil and oil filters, air filters, gasoline filters and other conventional maintenance.
大保養的間隔：大保養是基于小保養的存在，一般這兩種保養交替進行。間隔因汽車品牌車型差異各有不同，具體還請以廠商推薦為準。
The interval between large maintenance: large maintenance is based on the existence of small maintenance, generally the two kinds of maintenance alternate. The interval varies according to the different models of automobile brands. Specifically, please refer to the manufacturer's recommendation.
除了更換機油和機油濾清器之外，汽車大保養中還有以下兩個項目：
In addition to the replacement of oil and oil filters, there are the following two items in the major maintenance of automobiles:
1.空氣濾清器
1. Air filter
發動機在工作過程中要吸進大量的空氣，如果空氣不經過濾，其中的塵埃會加速活塞組及氣缸的磨損。較大的顆粒進入活塞與氣缸之間，還會造成嚴重的“拉缸”現象。空氣濾清器的作用就是濾除空氣中的灰塵、顆粒，保證氣缸中進入足量、清潔的空氣。
The engine sucks in a lot of air during its working process. If the air is not filtered, the dust will accelerate the wear of the piston set and cylinder. Large particles entering between piston and cylinder will also cause serious "cylinder pulling" phenomenon. The function of the air filter is to filter out the dust and particles in the air, so as to ensure that enough clean air is entered into the cylinder.
2.汽油濾清器
2. Gasoline filter
汽油濾清器的作用是為發動機提供清潔的燃油，過濾掉汽油的水分及雜質。從而使發動機性能達到優化，同時也為發動機提供了佳保護。
The function of the gasoline filter is to provide clean fuel for the engine and filter out the moisture and impurities of the gasoline. Thus, the engine performance can be optimized and the best protection can be provided for the engine at the same time.
通常在進行汽車保養時，技師會根據車子的具體情況做其他檢查，還會增加其他保養項目，車輛行駛一定公里數后（3萬以后、或更多）全車系統需要大維護了，全車油液如：剎車、轉向、助力、變速箱、都需要更換，當然有些是沒必要的（防凍液、及正時皮帶這些可視情況）至于清洗這些項目當然是做的好！其他的如輪胎、剎車片、這些安全部件還是要認真檢查一下的。
Usually in the course of vehicle maintenance, technicians will do other checks according to the specific conditions of the car and add other maintenance items. After a certain number of kilometers (30,000 or more) the whole vehicle system needs to be maintained. The whole vehicle oil such as brake, steering, boost, gearbox, need to be replaced. Of course, some of them are unnecessary (antifreeze, timing belt, etc.). As for cleaning these items, of course, they are well done! Others, such as tires, brake pads, and these safety components, should be carefully examined.
