"Hello, everyone, this is our new program, Lao Zhang dismantling the car. I'm Lao Zhang, an automotive engineer. This program," said a middle-aged man in labor protection overalls. He was still a little unnatural when talking.
This is a new era. There are various novel ways to make money. When Cui Enxi, the online star of kimchi country, makes money by live broadcasting, many people's ideas have been broadened.
This middle-aged man is actually a very honest mechanic. However, his nephew, the young man who is taking a camera to shoot him at this time, is a flexible man. He had a hunch that this would be a new opportunity to make a fortune, so he encouraged his uncle to start the program.
The investment is huge. After all, I have to disassemble a car. I don't know where my nephew came from. In short, I pulled a brand-new imported car, Tian Jiamei, and asked him to disassemble it and play it at the same time. In that case, he's not polite. After all, he likes the car after repairing it for half his life, It is a rare opportunity to disassemble a foreign imported car. The price is that he must face the camera and do a sideline he is not familiar with.
I have to pretend to be an automotive engineer. I'm just a car repair teacher. Anyway, I don't surf the Internet, so it's estimated that few people know me.
"We don't see much of this car in China," Lao Zhang continued. "What we see in the market are imported and smuggled. Especially recently, there was a serious car accident. It was this model of car, the unfortunate driver, also called Lao Zhang."
It's obviously purposeful to dismantle the car. Take advantage of the accident to attract attention.
"Well, first of all, this car is a class a car. It uses a 1.8-liter engine and a 4-speed automatic transmission. The fuel consumption is 6.8 liters per 100 kilometers. For a car with automatic transmission, the fuel consumption of this car is quite good." Lao Zhang said: "The whole car has a regular shape and is neither rustic nor foreign. Although it is rarely seen in China, it sells very well in the West. Now let's see what's special about this car."
"Let's lift it up first and look at its chassis." according to his nephew's plan, Lao Zhang began to introduce it. With his continuous introduction, it became more and more natural.
"Well, the front drive is a common structure. As I just said, the fuel tank does not have any baffle protection, so it is not suitable for going to the countryside." after looking at the chassis, I found the first defect. The fuel tank actually does not have any baffle protection. Moreover, it is still a synthetic fuel tank. In this way, the fuel tank is easy to be damaged in case of collision.
The country road is a restricted area for it. Even if the road splashes stones, it is easy to leak its fuel tank!
I really don't know what I think. Is it to save the weight of more than ten kilograms?
"Now, let's disassemble, starting with the bumper."
"We can see that the front bumper is made of multi-layer stamped steel plate, and the thickness is the lowest I've ever seen. If it is used for a frontal collision, coupled with the collapse of the engine, it can be said that it is barely qualified." Lao Zhang said, thought about it, and recited the above words according to the draft given by his nephew in advance.
"This is also the difference between the island car design and our design concept." Lao Zhang pretended to be an engineer and had to say that adding these words immediately improved his level: "We think that the stronger the structure of the car, the better. However, the islanders don't think so. They think that moderate deformation can absorb more collision energy, which is called active energy absorption. If we make an analogy, we pay attention to overcoming rigidity with rigidity, and they pay attention to overcoming rigidity with softness. If there is a frontal collision, maybe we can undertake the energy of collision, but if If it's a small area collision, we can look at the transmission route of the impact force. "
Where did his nephew find these statements? Lao Zhang thought and began to introduce that the consequences of a small-area collision were very tragic, which was directly transmitted to the cockpit. Moreover, the cockpit paid attention to overcoming hardness with softness, which suddenly deformed. Therefore, the drivers in the cockpit were absorbed with energy.
After talking about the front, Lao Zhang came to the back: "now, let's disassemble the rear bumper."
When he opened it, he immediately showed a surprised expression: "there is no bumper at the back, and foam plastic is in the back. Yes, soft, foam plastic! If this car has a rear end accident, it won't be able to protect the passengers at the back."
Lao Zhang's expression was exaggerated because he was really surprised.
The effect of this video is quite good. After all, it's a man who likes cars. It's definitely the standard configuration of successful men. For many people, they still can't afford to buy it for the time being, but they have to watch it. On the Internet, they point out rivers and mountains, watch all kinds of cars, and make enough comments. They have become a professional car critic, well, the so-called keyboard car God. They can't buy every kind of car We all know that they can point out the advantages and disadvantages of each car, especially amplifying the disadvantages without limitation, so as to show their rich knowledge.
After the release of this video, for a period of time, it has been growing with the first click through, hanging in the front page headlines of various websites, which has attracted the emotion of countless people. Unexpectedly, this car is so Jerry built!
Lao Zhang also jumped up and became a network celebrity because of this video. This is a later story. At least for now, they have caused a sensation.
However, after all, this is amateur. While this video is spreading rapidly on the network, professional evaluation has also begun. This is a collision research institution jointly composed of many insurance companies in China.
Their research results are also disseminated in the form of video, but there is no one in this video, only dubbing.
"The accident of a driver surnamed Zhang in Wucheng attracted the attention of our insurance institutions. After studying a large number of car accident videos, we found that this kind of small-area collision also occurs frequently. Therefore, we introduced this model in the collision test, which is called the small 25% overlapping frontal impact test. In this test, Our test vehicle will hit a hard and deformable retaining wall with a height of 1.5 meters at the speed of 64 km / h to detect the consequences of this impact. Now we know that the energy absorption and safety design of most models take the center of the vehicle body as the core, and we have achieved very good results in frontal collision, and our impact can just avoid this area. We want to be more careful The design strength of the A-pillar and the cockpit itself was strictly investigated. We chose a tianjiamei low configuration model purchased from the market. In the future, all our tests were based on the low configuration models on the market. "
After the introduction, the test video begins.
