"Hello everyone, everyone, here is our new program, Lao Zhang dismantles the car. I am Lao Zhang, an automotive engineer. This program" said a middle-aged man wearing a protective overall. When he was speaking, he still Slightly unnatural.

This is a new era, and there are all kinds of novel ways to make money. When Kimchi country’s celebrity Choi Eun-hee was making money by live broadcast, many people's thinking has also broadened.

This middle-aged man is actually a very honest car repairer, but his nephew, the young guy who is holding a camera and shooting him at this time, is a flexible-minded person. He has a foreboding. This will be a new opportunity to make a fortune, so, squeezing his uncle, started this show.

The investment is huge. After all, it’s going to take apart a car, and I don’t know where my nephew got the investment. In short, I’ll bring him a brand new imported car. Come over, let him disassemble and play it at the same time. In that case, he is not welcome. After all, a car that has been repaired for half a lifetime is also quite fond of the car. It is able to disassemble a foreign imported car. Rare opportunity. The price is that he has to face the camera and do a side job he is not familiar with.

I have to pretend to be forced, where I am an automobile engineer, I am just a car repair master. I don't go online anyway, so it is estimated that few people know myself.

"I don't see much of this car in China." Lao Zhang continued: "What I see on the market is imported and smuggled. Especially recently, there was a serious car accident. It was this model. The car, the unfortunate driver, is also called Lao Zhang."

This car was dismantled, obviously for a purpose. Taking advantage of this car accident, it attracted attention.

"Well, let’s first introduce it. This car is an A-class car with 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, this The fuel consumption of this car is already quite good." Lao Zhang said: "The whole car is well-formed, not local or foreign. Although it is rarely seen in China, it sells quite well in the West. Now, let us see, this What is special about this car."

"Let's get up first and look at its chassis." According to his nephew's plan, Lao Zhang began to introduce it. With his continuous introduction, it gradually became more natural.

"Well, the front front drive, the 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, and the fuel tank actually doesn't have any The baffle is used for protection, and the fuel tank of synthetic material is used, so that if it encounters a bump, the fuel tank is easily broken.

The road in the country is a restricted area for it, even if it is a highway, once the stones splash up, it is easy to leak its fuel tank!

I really don't know what I think, is it to save the weight of ten kilograms?

"Now, we dismantle, starting with the bumper."

"We can see that the front bumper is made of multi-layer stamped steel plates. The thickness is the lowest I have ever seen. If you use it for a frontal collision and the engine's collapse, it can be said that it is barely qualified. "Lao Zhang said, after thinking about it, he recites the above few sentences according to the draft given by his nephew in advance.

"This is also the difference between the island country car design and our design philosophy." Lao Zhang pretended to be an engineer. I have to say that the addition of these few words immediately improved his grade: "We think The stronger the car’s structure, the better. However, islanders don’t think so. They think that a moderate deformation can absorb more collision energy. This is called active energy absorption. If we are to make a metaphor, we are particular about rigidity. Conquer Gang, what they pay attention to is softness over rigidity. If there is a frontal collision, it may be able to withstand the energy of the collision, but if it is a small-area collision, we can look at the transmission route of the impact force."

Where did my nephew find these claims? While thinking about it, Lao Zhang began to introduce that the consequences of a small-area collision were very disastrous, and it was directly transmitted to the cockpit. What's more, the cockpit was designed to overcome rigidity by softness, which suddenly deformed, so the driving in the cockpit The member was also absorbed.

After finishing talking about the front, Lao Zhang came to the back again: "Now, let's disassemble the rear bumper again."

When he opened it, he immediately showed a surprised expression: "There is no bumper at the back, but foam is installed at the back! That's right, soft, foam! This kind of car, if there is a rear-end collision, then There is no way to protect the passengers behind."

Lao Zhang's expression was very exaggerated, because he was really shocked.

The effect of this video is quite good. After all, he is a man who likes cars. It is definitely the standard equipment for successful men. For many people, they can’t afford it for the time being, but they can’t afford it. Ah, on the Internet, I gave pointers, looked at various cars, made good comments, and became a professional car critic, well, the so-called keyboard car god. They know every kind of car, and they can point out the advantages and disadvantages of each kind of car, especially the unrestricted enlargement of the disadvantages, so that they can show their rich knowledge.

After this video was released, for a period of time, the number of first clicks has been growing wildly, and it has been hung in the front page headlines of various websites. It has attracted the emotion of countless people. Unexpectedly, this car is so cutting corners!

Because of this video, Lao Zhang jumped up and became an internet celebrity. This is something to do. At least for now, they have caused a sensation.

However, this is amateur after all. Just as this video is spreading rapidly on the Internet, professional-level evaluation has also begun. This is a collision research institution jointly formed by multiple insurance companies in Han China.

Their research results are also disseminated in the form of video, but there is no one in this video, only dubbing.

"This time, the accident of a driver named Zhang in Wucheng attracted the attention of our insurance agency. After studying a large number of car accident videos, we discovered that this small-area collision is also a frequent occurrence, so In the crash test, we introduced this model, the scientific name is the small 25% overlap frontal impact test. In this test, our test vehicle will crash into 1.5 meters at a speed of 64 kilometers per hour. Highly rigid and non-deformable retaining walls are used to detect the consequences of such impacts. Now we know that most of the models' energy absorption and safety design are centered on the center of the car body. They perform well in frontal collisions. This kind of collision can just avoid this area. Our purpose is to more rigorously examine the design strength of the car’s A-pillar and the cockpit itself. We chose a low-profile model of Camry purchased from the market. In the future, all our tests will be based on the low-end models on the market."

After the introduction, the video of the test began.
