How much do you know about cars? for

With the increasing popularity of automobiles in daily life, people know more and more about various related professional knowledge of automobiles.

Are there always some people around you? Facing the traffic on the road, they can know the name of every car on the road by their own cognition.

Even the displacement of each car is clear, and they can know when the new car will be on the market and how much it will cost.

In fact, some knowledge is usually the most common and neglected. Even these people may not understand. What are they?

Why is there only one rear fog light?

The first thing to explain to you is that this design is in full compliance with relevant laws and regulations.

Because the rear fog lights are red like the rear width indicator lights and brake lights, but the rear fog lights have stronger penetration and are more dazzling.

Therefore, in order to clearly distinguish the rear fog lights and not be mistaken for brake lights by the rear car, the design idea of "only one" is adopted, and a single rear fog light is located on the driving side.

Opposite is a white reversing light, and there is only one. But there are also many cars whose reversing lights are two symmetrical white lights, and there is only one fog light, and the other side is empty.

Why are the tires all black instead of colored?

Now there are more and more cars in the street, but the tires are only black.

This knowledge may not be understood by old drivers who have been driving all their lives. Why are the tires of cars running on the road the same color? If it is a colored tire, is it more beautiful?

In fact, the first tire in the world is white, because natural rubber is white and there is no additive in it.

Later, it was found that the service life of this kind of tire with carbon black was 4-5 times longer than that of the original natural rubber white tire.

With the development of automobile, there are more and more accidents caused by automobile tires, and the regulatory authorities have begun to pay attention to the wear resistance and aging resistance of tires.

Adding carbon black into the tire makes the tire more wear-resistant, has a longer service life and improves the driving safety.

Why are the front and rear bumper skins made of plastic?

In fact, at the earliest time, the bumper was made of metal. We saw some old cars in movies. The front bumper was silver, and many bumpers were made of iron in those days.

So why did the bumper of the car change to plastic later? Is it because the manufacturer is considering the cost?

There is no denying that cost is an aspect that manufacturers consider. The modern definition of plastics is already a polymer composite, and the cost of many plastics is not cheaper than that of metals.

The world's first plastic bumper was Fiat's. Plastic bumpers play a buffering role in the collision of pedestrians and are also a kind of protection for pedestrians.

Metal bumper is not easy to deform, and its energy absorption effect is more harmful and dangerous to pedestrians than plastic. Moreover, plastic itself is light in weight, which is definitely better than metal parts, reducing the weight of the whole vehicle.

Many luxury cars use aluminum alloy materials instead of steel plates to make covers and fenders, also in order to better absorb impact energy and reduce weight.

Why are more and more cars equipped with BOP suits?

BOP brand creates the code of conduct for optical owners. As one of the earliest companies to produce optical films in China, the owner of BOP brand Window Optics has gradually established its own core technology network after years of R&D investment!

Only by mastering technology can we make really good products. When other stealth car clothing brands are still promoting the concepts of "never turning yellow in ten years" and "never turning yellow in life" (not to mention being suspected of misleading consumers), BOP stealth car clothing industry is the first.

Under the premise of normal use by the owner, the phenomena such as water spots, water stains and matte film on the invisible car clothes are included in the warranty scope as product quality problems, which gives the owner real protection.
