First, the basic structure: a car generally consists of four basic parts: engine, chassis, body and electrical equipment.
2. Text: 19 From the end of the 20th century to the beginning of the 20th century, automobile designers devoted all their energies to the development and innovation of automobile mechanical engineering. In the first half of the 20th century, after the basic structure of the automobile was invented, automobile designers began to improve the external modeling of the automobile, and introduced concepts such as aerodynamics, fluid mechanics, ergonomics, industrial modeling design (industrial aesthetics) in succession, in order to make the automobile meet the different needs of people of all ages, classes and even cultural backgrounds in appearance, and make the automobile the best expression image combining science and art, and finally achieve the perfection.
Car stylists dress up cars as human bodies. For example: the eyes of a car-headlights; Mouth air inlet; Lung air filter; Vascular-oil circuit; Neural circuit; Heart engine; Stomach oil tank; Foot-tire; Muscle-mechanical part. Try to inject the cold machine into life, so that it has extraordinary artistic charm and gives people a sense of beauty. In the process of development, the forms of automobile body mainly experienced carriage, box car, beetle car, steamboat car, fish car and wedge car.
Third, the new car maintenance
Waxing a new car
In order to protect the car paint from being damaged during long-distance transportation, automobile manufacturers will spray a layer of wax on the car body, which is called transportation protection wax. This layer of wax is completely different from the light wax on ordinary new cars. When you arrive at your destination, you must take it off and then sell it.
New car waxing should pay special attention to the selection of suitable products. Improper selection will cause serious damage to car paint. Many car washes use kerosene to wax. Although the wax is opened, it will also cause tiny scratches on the car paint. New car transportation wax is divided into fat wax and resin wax. It is best to use environmentally-friendly wax-boiling water to open oil wax, which is extracted from orange peel. It has a strong degreasing function and will not damage the car paint. If it is resin wax, buy a bottle of special "dewaxing" car wash liquid. The price of car washing and waxing is generally between 100-400 yuan according to the grade of the car; If you make it yourself, buy detergent, depending on the brand and dosage. The price is between 20- 150 yuan.
New car paint protection
Protection of new car paint is more important than waxing. Carbon black in automobile exhaust, sundries in the air, acid rain and other invisible hidden dangers. From the first day of the new car on the road, the paint was oxidized. In order to prevent a beautiful car from becoming a "yellow-faced woman", new car paint protection needs waxing, but it is not ordinary wax.
There are two kinds of new car wax: one is called new car wax, and the other is called new car protection wax. These are two completely different waxes. New car wax should be used first, and then used after daily car washing. The unique super anti-oxidation and anti-corrosion function of the new car protection wax can last for one year once, and it will not be washed off in daily car washing. New car wax is a soft wax. Generally, there is no polishing agent in it, which can't stand the test of car washing. New car protective wax can choose invisible car clothes, 100 yuan. Can be used for more than a dozen times, each time the labor cost 20 yuan. You can also learn to operate with a sponge yourself.
New car internal protection
There are generally two kinds of materials for automobile interior, leather and chemical fiber. You'd better do maintenance immediately after you buy a new car. Leather has two kinds of polishes, wax and resin. Wax can only be polished, not protected, and at most waterproof; Resin-based leather polishing agent emphasizes the protective function of products, wear resistance, ultraviolet resistance and corrosion resistance. The protection of chemical fiber must distinguish between internal "cleaning agent" and internal "protective agent", which are completely different products. Interior protective agent generally contains silicone resin, which can form a protective film on the fiber surface, so that oil pollution will not directly erode chemical fiber, and ultraviolet rays will not oxidize interior materials, making it fade and turn white.
Indoor protective agents or cleaning protective agents can be divided into cotton wool cleaning agents, chemical fiber cleaning agents and leather cleaning agents. The price is between 50 yuan and 60 yuan. Spray it on the surface of chemical fiber and wipe it with a dry towel. Please remember at this time, don't forget the canopy above your head.
