With the development and perfection of China's economy, people have more and more choices of travel modes, and the automobile industry has gained unprecedented development opportunities. Cars have also entered thousands of households, which not only facilitates people's lives, but also improves the living standards of China cities. However, cars are often used frequently after purchase, and the working environment is complicated. Moreover, it is easily influenced by factors such as driving time, load bearing, driving speed, road conditions, driver's experience and auxiliary fuel used, which leads to different degrees of damage, aging, deformation and corrosion of automobile parts and engines, thus affecting the service life of automobiles. If we don't pay attention to it, it may cause some safety hazards and increase the danger for the future use of automobiles.
1. The significance of automobile maintenance
The main purpose of automobile maintenance is to maintain and repair the damaged parts, to ensure that the automobile is always in a good running state, which not only prolongs the service life of the automobile, but also avoids the huge financial trouble of automobile overhaul. At the same time, with the development of society, people are more and more picky about cars. They need not only the intact parts of the car, but also the cleanliness and beautification of the car. As a result, many car dealers and repair shops have specially launched additional products such as car beauty, car washing, car decoration and car maintenance consultants, which are also derivatives of the automobile industry and the trend of social development.
Good car maintenance can greatly reduce the energy consumption of the car, protect the safe use of spare parts and engines, eliminate potential safety hazards, achieve the purpose of energy saving and emission reduction, and prolong the service life of the car. Therefore, automobile maintenance has been accepted and valued by more and more car owners and repair shops. The contents of automobile maintenance referred to in this paper mainly include inspecting small cars after driving for a certain mileage and time according to the relevant technical standards of automobile maintenance in China, and adopting different special maintenance materials for preventive maintenance according to the different requirements of various parts, which can not only find the problems in the car in time, but also help to reduce the wear rate of automobile parts. Slowing down the speed of automobile life consumption, ensuring the safe operation of the automobile and making the automobile more practical can not only save maintenance funds for the owner, but also help the society to realize the optimal allocation of resources.

2. 1 body maintenance
Car body maintenance, also known as car beauty, mainly cleans the appearance of the car according to the requirements of the owner, and cleans various oxides, corrosives and dirt attached to the surface and interior of the car, such as mud, rain stains, oil stains and soot. Regular cleaning and maintenance can not only keep the appearance of the car clean and tidy, but also prolong its service life. Nowadays, people are more and more critical of cars, and the maintenance of cars gradually goes deep into the cleaning of the center console, seat maintenance, wheel maintenance and glass clarity maintenance.
2.2 In-vehicle maintenance
Body maintenance is mainly to ensure the safe operation of the car. The main maintenance parts are as follows: lubricating oil application area, fuel assembly, cooling system, braking system, engine and other important parts. These parts are the key to driving the car. Proper maintenance will make these important parts run safely and reliably, otherwise it will shorten the service life of the car, even leave hidden dangers and bring danger to passengers. Therefore, in-car maintenance is essential.
2.3 overall renovation
The overall renovation is mainly aimed at the maintenance and renovation of some auxiliary parts of the car, such as the cleaning and renovation of scratches on the bumper of the car body, the repair of the wheel hub, and the removal of scratches on the leather of the seat. At the same time, it also includes the renovation and maintenance of paint falling from all parts of the car body, which makes the car look brand new. Regular maintenance can prevent the damage of the car from deepening and save unnecessary car maintenance expenses for the owner.

3. 1 engine maintenance
The engine is the heart of the car, which provides power for the car and is the propulsion source of the car. Therefore, engine maintenance is particularly important. First of all, the engine needs to choose high-quality lubricating oil. If you don't know enough about this, you can choose according to the lubricating oil grade specified by the automobile manufacturer. Secondly, check the oil filter regularly, because lubricating oil has a shelf life. Once the quality of the filter element is not up to standard, it must be replaced. In addition, it is necessary to check the ventilation of the crankcase. Gas exchange valve is the key to good ventilation. If there are too many pollutants, the air exchange valve will be blocked, which will lead to poor ventilation, increase energy consumption and easily cause engine wear. The water tank of the engine is also the focus of maintenance, and the owner needs to check whether the water tank is rusty from time to time to avoid reducing the water cooling capacity due to rust; Finally, spark plugs must also be inspected regularly. Because the spark plug is a key part that affects various systems of the automobile, if the spark plug is damaged, it must be replaced immediately, otherwise it will have an important impact on the normal work of the engine.
3.2 Vehicle Chassis Maintenance
The chassis of an automobile needs to be cleaned regularly to keep the chassis in a clean and dry working environment and avoid excessive sediment and dirt attached to the chassis. If the sediment is not cleaned in time, it will agglomerate, which will increase the friction of various parts of the automobile chassis and reduce the service life of the automobile chassis parts. In addition, the chassis is the gathering place of four systems, namely, transmission system, driving system, steering system and braking system. The covering of deposits will also affect the normal work of these four systems, such as fenders and exhaust pipes. To increase the frequency of cleaning, send it to the garage regularly for thorough cleaning. Car owners should also pay attention to driving on flat roads as far as possible, because there may be uneven parts on the bumpy ground, which will directly rub the ground and damage the chassis of the car.
3.3 tire maintenance
Tires are the easiest place to maintain and the easiest place to ignore. It is exposed to the air and affected by road conditions. If it is a flat asphalt road, the tire will not be damaged. If it is a sand road or a bumpy gravel road, it is easy to be embedded in the gap of the tire. Over time, it will aggravate the damage of tires and even produce a puncture. In addition, if the temperature is too high, the tire is made of rubber, which is easy to soften and deform. At this time, start the car and run. Therefore, the owner needs to check whether the tire is deformed, damaged or cracked, so as to replace the tire in time to prevent further damage and ensure safe operation.
label
Because of the high frequency of car use, long driving time and complicated road conditions, cars will be damaged to varying degrees. If you accumulate blindly, it will lead to more and more hidden dangers of cars, and even scrap them. At that time, it will not only need to go back to the factory for maintenance, but also delay the travel arrangement of the owner and waste time. Therefore, regular maintenance in daily life is an important link to ensure the extension and timely discovery of problems, which can not only save money and time, but also
