小保養
Minor maintenance
小保養一般是指汽車行駛一定距離后，為保障車輛性能而在廠商規定的時間或里程做的常規保養項目。主要包括更換機油和機油濾芯。
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.
小保養的間隔：
Interval of minor maintenance:
小保養的時間取決于所用機油和機油濾芯的有效時間或里程。不同品牌級別的礦物質機油、半合成機油、全合成機油有效期也不盡相同，可以廠商推薦為準。機油濾清器一般分常規及長效兩種，常規機油濾清器隨機油一起更換，長效機油濾清器使用時間更長。
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.
小保養中的用品：
Supplies for minor maintenance:
1.機油
1. Engine oil
機油就是發動機運轉的潤滑油。能對發動機起到潤滑、清潔、冷卻、密封、減磨等作用。對于降低發動機零件的磨損，延長使用壽命有著重要的意義。
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.機油濾清器
2. Oil filter
機油濾清器是過濾機油的部件。機油中都含有一定量的膠質、雜質、水分和添加劑;在發動機工作過程中，各部件摩擦產生的金屬屑、吸入空氣中的雜質、機油氧化物等，都是機油濾清器過濾的對象。若機油不作過濾，直接進入油路循環，將會對發動機的性能和壽命產生不利的影響。
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.
大保養
Major maintenance
大保養的內容：
Contents of major maintenance:
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。
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.
大保養的間隔：
Interval of major maintenance:
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。
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.
大保養中的用品：
Supplies in major maintenance:
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 changing the oil and oil filter, there are two items in the major maintenance of the vehicle:
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。空氣濾芯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 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化，同時也為發動機提供了保護。
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.
通常在進行汽車保養時，工作人員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，切莫被忽悠了）至于清洗這些項目當然是做的好！關鍵費用太貴（查查手冊或問問朋友有個底）效果有，但不會明顯！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, 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.
