Chapter 184 Shining the audience (final)

No matter how you look at it, Fred is unwilling to admit that Mercedes-Benz has solved the brake lock-up situation. Dafeng Motor has used it for so many years and invested so much money without any substantial progress. How could there be a result so soon?

However, when he thought that the electronic injection system was first developed and designed by Zhou Fei, the founder of Feichi Company, Fred felt a little panicked for no reason. It seemed that there was nothing impossible for such a thing to happen to Feichi Company...

Fred decided to keep listening.

Sure enough, the commentator's next words verified Fred's thoughts.

"I know that many people are already speculating whether our Mercedes-Benz company has solved this problem, otherwise why would we say it?"

The narrator smiled and continued, "That's right, as you can imagine, after the unremitting efforts of Mr. Zhou of our company, we have finally developed a system that can prevent the wheels from locking up. We call it the ABS anti-lock system." Lock Brake System, the English full name is Antilock Brake System!"

As soon as the commentator finished speaking, there was a burst of discussion all around. Everyone's face was full of disbelief. They couldn't imagine that such a worldwide problem would be solved by Feichi Company like this?
"Is it true? If it is true, wouldn't it have saved thousands of lives!"

"This is amazing, we Huaxia finally produced a decent car manufacturer!"

"Antilock Brake System... Judging from the name, it seems to be a good invention?"

"There is no evidence for what they say, and there is no real reference. I don't really believe what they said. It is probably a publicity gimmick."

Among the onlookers, some were surprised, skeptical, and some held a wait-and-see attitude. Fred looked at each other with a serious face. He dared to say such words in front of so many people at the Geneva Motor Show. If the final development is not completed, it must be a major breakthrough!

"Next, I will introduce this ABS system to you in detail. Please look at the big screen."

As he said that, the large screen above the exhibition area suddenly lit up, and then the word "ABS" appeared on the screen. In order to make this explanation go smoothly, the narrator specially participated in a week of professional training before coming. training.

The video for the explanation is mainly in English, supplemented by Chinese subtitles.

"This ABS system is composed of three parts: wheel speed sensor, electronic control unit and actuator. Each part is in..."

When everyone's eyes were focused on the big screen, the commentator cooperated with the video and began to explain seriously.

"...During braking, the ABS will quickly determine the locked state of the wheel based on the speed signal from each wheel speed sensor, and close the normally open input solenoid valve on the wheel that starts to lock the wheel, so that the braking force remains unchanged. If the wheel continues to be locked, the normally closed output solenoid valve is opened, and the brake pressure on this wheel moves down rapidly due to the pipeline directly leading to the brake fluid storage tank, which prevents the wheel from being completely locked due to excessive braking force .”

"The specific working process can be understood by referring to this structural diagram. For example, when the electronic control device determines that the right front wheel tends to be locked, the electronic control device energizes the liquid inlet solenoid valve that controls the brake pressure of the right front wheel, so that The right forward fluid solenoid valve turns to the closed state, and the brake fluid output from the brake master cylinder no longer enters the right front brake wheel cylinder..."

Although some vocabulary is difficult to understand, with the video played on the screen, most people can still roughly understand the specific working principle and working process of ABS.

"What I just said is just a systematic introduction to the ABS system, but many people may not have an intuitive feeling for the specific functions of this system, so in order to help everyone better understand the functions of the entire system, we have specially carried out a practical Car test, let’s take a look at the video taken during the test.”

Soon, the picture on the screen changed to the ABS performance test experiment conducted by Mercedes-Benz some time ago!

The entire video lasted about 10 minutes, and all the onlookers had watched the entire content. At this moment, all doubts had disappeared, replaced by shock!
No one in the audience is blind, as long as they carefully read the whole test process, they can clearly understand how good the effect of the ABS system is!

"It's amazing how little the braking distance has changed all of a sudden!"

"The phenomenon of body sideslip has also been significantly improved, awesome!"

"Judging from the brake marks on the ground, after installing the ABS, the brakes are not locked and sliding all the time, but rolling and sliding. It really solves the problem of always locking!"

"This is the good news for us. With this system, not to mention that traffic accidents can be prevented, but at least the traffic accidents caused by brake lock can be reduced by more than half!"

…………

After the video was played, everyone couldn't calm down anymore. They looked at each other with surprised and happy expressions, and couldn't help discussing excitedly.

And Fred, who was behind the crowd, looked at the big screen with a dull expression, and he really guessed right, the Mercedes-Benz company once again took the lead in completing this task!
But how is it possible?

Why is it that things that other companies have racked their brains and failed to do have become so simple with Feichi Company?

First, the engine's electronic fuel injection system, and then the current brake lock. Obviously, the two are not in the same field, but Zhou Fei did it unexpectedly!

Know it all?

All-around genius?

Fred felt that both words could describe Zhou Fei!

The air suddenly became sour, even more sour than eating lemons!

"Perhaps, the video that was played just now was just made by them on purpose, and the actual effect may not be that good..." Jonathan couldn't help but murmured.

"Except for you, no one else would dare to do such a stupid thing!" Fred really wanted to slap him in the face. How dare Jonathan say such stupid things?

"Can I ask if this system is open for assembly?" Someone in the crowd suddenly asked.

Such a good invention, who would not want to install a set on their own car, but successful testing and mass assembly are two different things, which also involves the issue of assembly technology.

"At present, our Mercedes-Benz company has completed all the development of this system, and intends to open it to the Golf as an option. It is up to the customer to choose whether it is enough to install this system. By next year at the latest, we will introduce it to all its models. All are assembled with ABS system!"

The narrator replied with a smile.
