小保养
Minor maintenance
小保养一般是指汽车行驶一定距离后，为保障车辆性能而在厂商规定的时间或里程做的常规保养项目。主要包括更换机油和机油滤芯。
Minor maintenance generally refers to the routine maintenance items done at the time or mileage specified by the manufacturer to ensure the vehicle performance after driving a certain distance. It mainly includes changing engine oil and engine oil filter element.
小保养的间隔：
Interval of minor maintenance:
小保养的时间取决于所用机油和机油滤芯的有效时间或里程。不同品牌级别的矿物质机油、半合成机油、全合成机油有效期也不尽相同，可以厂商推荐为准。机油滤清器一般分常规及长效两种，常规机油滤清器随机油一起更换，长效机油滤清器使用时间更长。
The time of minor maintenance depends on the oil used and the effective time or mileage of the oil filter element. Mineral oil, semi synthetic oil and fully synthetic oil of different brands have different validity periods, which can be recommended by the manufacturer. The oil filter is generally divided into conventional and long-term. The conventional oil filter is replaced with the oil, and the long-term oil filter has a longer service life.
小保养中的用品：
Supplies for minor maintenance:
1.机油
1. Engine oil
机油就是发动机运转的润滑油。能对发动机起到润滑、清洁、冷却、密封、减磨等作用。对于降低发动机零件的磨损，延长使用寿命有着重要的意义。
Engine oil is the lubricating oil for engine operation. It can lubricate, clean, cool, seal and reduce wear of the engine. It is of great significance to reduce the wear of engine parts and prolong the service life.
2.机油滤清器
2. Oil filter
机油滤清器是过滤机油的部件。机油中都含有一定量的胶质、杂质、水分和添加剂;在发动机工作过程中，各部件摩擦产生的金属屑、吸入空气中的杂质、机油氧化物等，都是机油滤清器过滤的对象。若机油不作过滤，直接进入油路循环，将会对发动机的性能和寿命产生不利的影响。
The oil filter is the component that filters the oil. Engine oil contains a certain amount of gum, impurities, water and additives; In the working process of the engine, the metal chips generated by the friction of various components, impurities in the inhaled air, oil oxides, etc. are the filtering objects of the oil filter. If the engine oil is not filtered and directly enters the oil circuit for circulation, it will have an adverse impact on the performance and service life of the engine.
大保养
Major maintenance
大保养的内容：
Contents of major maintenance:
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。
Minor maintenance items are covered by major maintenance, which means that all items included in minor maintenance are generally implemented during each major maintenance. The major maintenance items will also have different details according to different vehicle designs of different manufacturers. But in general, it will have a brief commonality. Major maintenance includes changing engine oil and routine maintenance of engine oil filter, air filter, gasoline filter, etc.
大保养的间隔：
Interval of major maintenance:
大保养是基于小保养的存在，一般这两种保养交替进行。间隔因汽车品牌车型差异各有不同，具体还请以厂商推荐为准。
Major maintenance is based on minor maintenance. Generally, the two types of maintenance are carried out alternately. The interval is different due to the difference of automobile brands and models. Please refer to the manufacturer's recommendation for details.
大保养中的用品：
Supplies in major maintenance:
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 changing the oil and oil filter, there are two items in the major maintenance of the vehicle:
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。空气滤芯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 needs to absorb a lot of air during operation. If the air is not filtered, the dust in it will accelerate the wear of piston bank and cylinder. Larger particles entering between the piston and the cylinder will also cause serious "cylinder pulling" phenomenon. The function of the air filter element is to filter out dust and particles in the air and ensure sufficient and clean air in 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化，同时也为发动机提供了保护。
The function of gasoline filter is to provide clean fuel for the engine and filter out the water and impurities of gasoline. Thus, the engine performance is optimized and the best protection is provided for the engine.
通常在进行汽车保养时，工作人员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，车辆行驶一定公里数后（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，切莫被忽悠了）至于清洗这些项目当然是做的好！关键费用太贵（查查手册或问问朋友有个底）效果有，但不会明显！其他的如轮胎、刹车片、这些安全部件还是要认真检查一下的。
Usually, during vehicle maintenance, the staff will conduct other inspections according to the specific conditions of the vehicle, and other maintenance items will be added. After the vehicle has driven a certain number of kilometers (after 30000 or more), the whole vehicle system needs major maintenance, and the whole vehicle fluids such as brake, steering, power assistance and gearbox need to be replaced, Of course, some are unnecessary (antifreeze, timing belt and other visual conditions should not be fooled). As for cleaning these items, of course, they are well done! Key costs are too expensive (finally check the manual or ask a friend for a bottom) the effect is good, but it will not be obvious! Other safety parts such as tires, brake pads and so on should be carefully checked.
