大保养的内容：小保养的项目，都是被大保养所涵盖的；意思就是说：每次大保养时，一般都会执行小保养所含的所有项目。而大保养的项目依照不同厂家的不同车辆设计，也会有细部的不同区分。但大致上，它还会有一个简略的共通性。大保养进行的内容为更换机油和机油滤清器、空气滤清器、汽油滤清器等的常规保养。
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.
大保养的间隔：大保养是基于小保养的存在，一般这两种保养交替进行。间隔因汽车车型差异各有不同，具体还请以厂商为准。
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.
除了更换机油和机油滤清器之外，汽车大保养中还有以下两个项目：
In addition to the replacement of oil and oil filters, there are the following two items in the major maintenance of automobiles:
1.空气滤清器
1. Air filter
发动机在工作过程中要吸进大量的空气，如果空气不经过滤，其中的尘埃会加速活塞组及气缸的磨损。较大的颗粒进入活塞与气缸之间，还会造成严重的“拉缸”现象。空气滤清器的作用就是滤除空气中的灰尘、颗粒，保证气缸中进入足量、清洁的空气。
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.汽油滤清器
2. Gasoline filter
汽油滤清器的作用是为发动机提供清洁的燃油，过滤掉汽油的水分及杂质。从而使发动机性能达到优化，同时也为发动机提供了佳保护。
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.
通常在进行汽车保养时，技师会根据车子的具体情况做其他检查，还会增加其他保养项目，车辆行驶一定数后（3万以后、或更多）全车系统需要大维护了，全车油液如：刹车、转向、助力、变速箱、都需要更换，当然有些是没必要的（防冻液、及正时皮带这些可视情况）于清洗这些项目当然是做的好！其他的如轮胎、刹车片、这些部件还是要认真检查一下的。
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.
