More and more people are driving. You know all the little things about these cars!
I have to say that people's demand for cars is really growing now. You can make your car very comfortable when traveling or visiting relatives. As a tool for people to travel, the car is also a sophisticated instrument, which itself contains a lot of interesting and unpopular knowledge. Some things look ordinary, which we can usually see and use, but because they are so ordinary, many people ignore their uses and origins. Let's talk about these cold knowledge thoroughly today and see if you know everything. If you know everything, then you are too powerful.
1 day, let's talk about the small black spots on the car glass. In fact, whether it is on the bus glass or the car glass, as long as you look carefully, you will find circles of small black spots inside the bag. The existence of these small black spots seems inconspicuous, but it has a great effect. Many people also know that the glass of a car is fixed with glue. When a car passes the sun in hot weather, the temperature of the metal frame around the glass will continue to rise, leading to expansion, and the glass will be in danger of explosion. In winter, the temperature outside is low and the car is warm. This temperature difference will also lead to glass explosion. The appearance of these small black spots can play the role of transition energy, can buffer the stress such as cold shrinkage, and make the automobile glass quickly heat up or cool down, thus reducing the risk of glass explosion.
The second point is, do you see what the line on the engine bar is for? When we learn to drive at school, whether driving in a straight line or turning, the coach always shows us two straight lines on the hood. But do you know what these two straight lines are for? In fact, it mainly plays the role of diversion, which increases the stability of the car when driving and the rigidity of the hood.
The third is the antenna of the car, the antenna of the car, and someone named it shark fin. In the past, many cars had this kind of thing, all of which knew how to receive signals, but now cars seem to be equipped with these antennas, and we don't often see them.
There is a thin line on the windshield behind the fourth car. In fact, these wires on the rear window are not all antennas, but most of them are heating wires. On foggy and snowy days, the rear window will be foggy. As long as the defogging button is pressed, the frost or milk attached to the glass by these heating wires will melt quickly through the electronic heating of the glass, so as to achieve some defrosting and defogging effects and make the rear view clearer, you know?
The fifth is whether there is one or two rear fog lights. Many netizens also have such an annoyance, which is normal. Lights are installed in pairs. Why is there only one rear fog light and some cars have two? In fact, the state stipulates that rear fog lamps must be installed, but there is no special provision for installing several.
In order to save costs, some models installed one, while others installed two.
