What we usually sayVehicle maintenanceThe work carried out mainly in the area of the extension of the useful life of cars, from maintaining their state of technology, has three main aspects:
1. Appearance maintenance: appearance maintenance is also known as car beauty. The main objective is to remove all oxidation and corrosion from the body and in the vehicle and then protect it, highlighting as much as possible the beauty of the vehicle. It includes, inter alia, painting maintenance, carpet maintenance on mattresses, bumpers, skirt maintenance, meter maintenance, plating processing maintenance, leather plastic maintenance, tyres, {the useful life of tyres is generally 2-3 years or approximately 60,000-100,000 kilometres. Tires should be replaced immediately at a depth of 1. 6 mm (minimum grinding). Tyres exceeding their shelf life (especially spares, with a spare life of approximately three years) have declined overall performance. } windshield maintenance, engine exterior maintenance, etc。
Ii. Indoor maintenance: appearance maintenance is intended to keep the car young and within vehicles is intended to keep hundreds of thousands of kilometres unrepaired and to ensure that the vehicle is in the best technical condition. It consists mainly of engines, chassis, maintenance of body electrical, etc。
1. The surface of transmissions, such as engines and gear tanks, is rusted by the fact that they are often in direct contact with air, and the long-term natural discharge of bottles affects their useful life. The best way is to run the car every few days for 30 to 40 minutes. In addition, the fact that cars are always used short distances can also cause injuries to vehicles, which are always moving but not far away, is an important cause of injuries。
2. The oil in the warp axle boxes cannot be added to, and cannot be added to, the excess of the oil, which would increase the gearing resistance of the rotor poles and would also increase the amount of oil spilled over the walls of the cylinders. Excess oil leads to an increase in chamber carbon and lower engine power, thus affecting emissions. When the oil is inspected or added by the owner, it shall be added at the scale above the oil ruler, the fluid level of the oil shall not exceed the limit of the scale, the minimum of which shall not be below the lower of the scale, and the fluid level of the oil shall normally be added to the position of the middle of the two scales。
The effect of excessive maintenance frequency is that you have to go to the repair plant on a regular basis and that, in the long run, you will have to pay extraordinary hours and materials, some of which are wasteful. Therefore, the scientific determination of the spacing miles of the various maintenance operations will not only keep cars in good technical condition on a regular basis, but also save you maintenance and repair costs. In determining the vehicle maintenance cycle, appropriate adjustments should be made to the vehicle's own technical condition and actual conditions of use, taking into account the maintenance cycle recommended by the vehicle manufacturer. New vehicles that are generally in good technical condition and are used under good working conditions may be used for an appropriate extension of the maintenance period, which should be reduced if the vehicle is in poor technical condition or in poor operating conditions。
4. Full use of free testing: automobile manufacturers are now increasingly focusing on after-sales services, thus benefiting the owners of cars from frequent free testing. Many of these free testing activities appear to be simple and, in the view of the owner, not substantial, but they are very beneficial. The owner could use these free-of-charge check-ups to conduct a full medical examination of car-lovers, detect some potential failures in a timely manner and eliminate the risks of those failures, thus saving high future maintenance costs。
As far as possible, the maintenance of a better-technical and specialized repair plant is complete, as many car owners feel, and a certain sum of their own cars (e. G., engines) are left unmanageable after the break-up and maintenance, with “hospital” treatment taking place over time, which is particularly common in imported vehicles. Why is this happening? The reasons for this are multiple, mainly in terms of repair workers ' assembly techniques and the quality of spare parts。
6. Proper use of oil: the proper use of oil consists of two aspects: fuel and lubricants. Inadequate fuel selection can easily cause breakdowns such as jamming and misfostering of fuel filters, resulting in a lack of speed, acceleration and rising fuel consumption of engines, as well as accelerating the wear of cylinders and affecting engine life. As a result, inappropriate fuel selection increases the maintenance and repair costs of vehicles. The quality of lubricating oil varies widely from brand to grade, and prices vary widely. How can lubricant be chosen to meet both the requirements for lubrication and the costs involved? The basic principle is to be able to meet the requirements for the use of vehicles and to adjust them when they are actually used。
7. The performance of brake oil has a critical impact on the overall safety of vehicles and, as brake oil is used for long periods of time to absorb the water in the air and can become evaporated when it is heated, causing the brake to fail, it must be replaced on a regular basis (40,000 km)。
Iii. Car retrofitting, such as deep scratching diagnosis, management, multi-material bumper repair, hard wound repair for wheel rims, leather, fibre-optic material refurbishment, engine colour renovation, etc。
Vehicle maintenance is divided into two categories: regular maintenance, with routine maintenance, primary maintenance, secondary maintenance; and non-regular maintenance, with drying and seasonal maintenance. The main tasks involved in vehicle maintenance are cleaning, inspection, tightness, adjustment and lubricants. However, with the development of science and technology and the automobile industry, advanced computer-based technologies have been widely applied in cars, leading to the intellectualization of future cars, and hence the new content of vehicle maintenance。
