First, the body maintenance. Car body maintenance is also called car beauty. The main purpose is to remove all kinds of oxidation corrosion inside and outside the car, and then protect it to highlight the beauty of the car as much as possible. Mainly includes: car paint maintenance, cushion carpet maintenance, bumper and skirt maintenance, instrument panel maintenance, electroplating processing maintenance, leather plastic maintenance, tire and hub maintenance, windshield maintenance, chassis maintenance, engine appearance maintenance, etc.
Second, car maintenance. The purpose of car body maintenance is to keep the car young forever, while the purpose of car interior maintenance is to make the car travel hundreds of thousands of kilometers without major repairs and ensure that the car is in the best technical condition. It mainly includes: maintenance of lubrication system, fuel system, cooling system, braking system and carburetor (injector).
Third, the body is refurbished. Such as diagnosis and treatment of deep scratches, repair of multi-material bumper, repair of hub (cover) hard injury, renovation of leather and chemical fiber materials, renovation of engine color and so on.
Automobile maintenance is divided into two categories: regular maintenance and irregular maintenance. Regular maintenance includes: daily maintenance, primary maintenance and secondary maintenance; Non-scheduled maintenance includes running-in maintenance and seasonal maintenance. The main work of car maintenance is nothing more than cleaning, inspection, fastening, adjustment and lubrication. However, with the development of science and technology and automobile industry, various advanced technologies, mainly computers, are widely used in automobiles, which makes the future automobiles gradually intelligent, so the contents of automobile maintenance are endowed with new connotations. Automobile maintenance is a complex work with high technical content, which is difficult to be completed by drivers themselves and needs to be carried out in automobile maintenance enterprises. At present, there are still some automobile maintenance enterprises in our country that stick to the traditional maintenance concept, the maintenance equipment and tools are outdated and the maintenance methods and means are still the same, which can not meet the needs of modern automobile development at all. In addition, the service quality of some maintenance enterprises is worrying. In order to make huge profits, they "operate behind the scenes". In terms of maintenance, the old ones are filled with new ones, the inferior ones are filled with good ones, and the maintenance and replacement fees are very expensive. Therefore, drivers and friends must be reminded that when maintaining their cars, they must choose a maintenance company with strong technical force, reliable service quality and good reputation, instead of not maintaining their cars in order to save trouble and money, so as not to lose big because of small.
Tips for car maintenance:
Maintenance of air filter: The function of air filter is to purify the air entering the cylinder. If the air filter is too dirty, it will hinder the smooth flow of air and increase fuel consumption.
Removal of carbon deposit: The increase of carbon deposit in the combustion chamber will easily lead to the spontaneous combustion of combustible mixture, which will lead to the decrease of power, so it is necessary to carefully remove carbon deposit in the combustion chamber and reduce unnecessary fuel consumption.
Muffler maintenance: Mufflers are designed to reduce noise. If the muffler is broken and damaged, it will hinder the smooth exhaust and increase fuel consumption. Therefore, attention should be paid to the function of muffler at ordinary times, and the damage should be eliminated or replaced in time.
Check the spark plug: the function of the spark plug is to introduce high-voltage electricity into the cylinder of the engine, generate sparks between the electrodes and ignite the mixture. The size of spark plug gap and carbon deposit have a direct impact on power and fuel consumption.
V. Adjust the tire pressure: After the tire is inflated according to the standard, it will naturally consume a part during use. The reduction of tire pressure has a great impact on driving resistance, tire life and fuel consumption, so it is necessary to ensure that the tire pressure is within the normal range.
Sixth, we must ensure braking performance: poor braking performance makes it difficult to ensure driving safety and will also affect engine fuel consumption. Therefore, the correct maintenance and adjustment of the braking system is also an aspect of safety and fuel saving.
Regular maintenance of the engine: preventive maintenance of the engine should be done at least once a year, because the engine will burn more fuel if it is out of tune for a long time.
