Rebirth of the Auto Giant

In the cab, Lin Zhengtang, the head of the service department, acted as the temporary driver, and Wang Shi was in the co-pilot position. In a row of sleepers behind him, two people from the computer department, Zhai Liangpeng and Weng Xinyuan, were sitting, holding notebooks and recording test questions at any time.

On the carriage behind, stood everyone from the service department, as well as two bodyguards, Zhang Long and Zhao Hu.

Lin Zhengtang stepped on the pedal slowly, and the car made a low beeping sound. The noise was originally lower than that of traditional engines, and with the addition of the muffler, the sound was much quieter than during the test.

"Master, this accelerator is too light. It's so light that even I'm not used to it. It feels like I'm flying in the clouds." Lin Zhengtang said.

Compared with the traditional throttle lever, the throttle of the high-pressure common rail system is controlled by a computer. The throttle position sensor installed on the accelerator pedal transmits the driver's signal to refuel to the computer instructions. The computer then obtains the engine speed of each cylinder based on the camshaft position sensor signal.

According to the operating conditions, the opening size of the solenoid valve on the electronically controlled injector is controlled to increase the size of the fuel injection to achieve the purpose of refueling.

Compared with the traditional pull rod that pulls the high-pressure oil pump to achieve the purpose of refueling, the high-pressure common rail system only gives a signal instruction to the computer, with low resistance and high flexibility. No wonder Lin Zhengtang said that it feels like flying in the clouds.

"It's not that outrageous, but compared with the traditional one, it is indeed much more flexible and lighter. With this, everything in the future will not be controlled by a computer. Failure of each sensor can also be detected by the computer. The computer department will develop a special detection

The fault diagnosis system for each sensor of the engine is installed in the computer. When there is a fault in the engine, you can check it with the computer. Based on the fault code obtained, you will know which sensor has a problem, or the alarm indicator light of each temperature keeps flashing, or you can design a

Buzzer sound to achieve."

"In the future, car fault diagnosis will all be done through computers, so I asked you to learn English a few years ago, and now you are using it. In the future, when our products are launched on the market, computer diagnosis will definitely be used in after-sales service." Wang Shi looked at it.

He said to the driver Lin Zhengtang from the front.

A few years ago, when Wang Shi decided to accept Lin Zhengtang as his apprentice, considering the future development of car services, he asked him to go to night school to learn English. Over the past few years, Lin Zhengtang's English level has even surpassed that of his master Wang Shi. Now

I have been using my weekends to study English at a foreign language university.

Thinking of all that happened back then, Lin Zhengtang admired Wang Shi in his heart.

Not only did he teach me the skills of repairing cars, he also taught me English in advance. Without the master, I would still be an unemployed vagrant without even a stable job. Not to mention being the director of a department, I also learned English.

Nowadays, some foreign technical books can be read by oneself.

Thinking of this, Lin Zhengtang looked at the master gratefully and said, "Thank you, master."

"I've finished saying that you are my apprentice, follow me well, and the master will give you a level you can't imagine, whether it's money or social status."

"How many months is Zhuo Zixia now?" Lin Zhengtang's wife Zhuo Zixia is now pregnant. This is what Wang Shi heard, but he doesn't know how many months ago.

As a master, I really don’t know this at all, so I am a bit incompetent.

"Seven months." Lin Zhengtang became excited when he mentioned his wife.

"The due date is at the end of November. This month is not good. The weather is so cold, which is inconvenient for both adults and children." Wang Shi said.

"No, my grandpa said the same thing. When he thinks about the baby being born at the end of the year, he keeps thinking. My grandpa has bought a lot of gauze and slowly cut it into pieces, washed them, dried them and stacked them for use later.

Now Zhuo Zixia has been told not to go to work, and my grandfather watches her every day and follows her wherever she goes, fearing that she will be accidentally bumped into by some naughty child in the alley."

"It's too early to prepare diapers now." Wang Shi was speechless.

"Who said it wasn't the case? I tried to persuade him, but grandpa didn't listen. Then I left it to him. He might as well be busy with some things. Now, in addition to having enough food and sleeping, grandpa's great-grandson is also here. Now the family has also hired a nanny.

The lady who does the cooking and housework is from the same alley. She is nice and quick with her hands and feet, so I can rest assured." Lin Zhengtang said.

"How much does it cost per month?" Wang Shi asked.

"One hundred and eighty, I cook, do housework, and sometimes help at the table. There are some things that are not convenient for my grandfather."

"One hundred and eighty is not too much, not too much, that's fine. My neighbors in the same alley can use it with confidence."

"Yes, my grandfather has become much more energetic after he became pregnant. Now he no longer collects rags. From now on, he won't listen if I tell him not to. Now that Zhuo Zixia is pregnant, he won't even ask you to tell him.

Go and guard at home, afraid of any accidents." Lin Zhengtang was full of pride when he mentioned his wife, grandfather, or the unborn little life at home.

After the car left Beijing, Lin Zhengtang still couldn't find any problems in the test. In his words, everything was perfect.

"Let me do it." You have never seen a high-pressure common rail system. Compared with the traditional throttle, it is of course perfect.

Wang Shi had driven a lot before crossing over, and he knew how sensitive the accelerator was as soon as he tried it.

I switched to Wang Shi to drive again. After driving for a while, I checked the data in each table on the stop meter board. Everything was normal, Wang Shi said while driving.

"Zhai Liangpeng, please remember that the sensitivity of the throttle is not very good, and it tends to get stuck when going uphill. This should not be a mechanical problem, but may be related to the computer. You can go back and optimize the ECU electronic control unit to address this problem.

Program." Wang Shi said.

"Okay." Zhai Liangpeng and Weng Xinyuan replied in unison while writing down.

"There is no need to be stressed. If there are problems with the program you just wrote, it is normal. If there are no problems, it is abnormal. Only after continuous testing and optimization can the program be perfect." Wang Shi comforted the two of them.

Computer programming is a mental job, which not only requires personnel to have extremely high knowledge of computer programming, but also requires programmers to have a high level of thinking.

Later, Wang Shi also discovered some problems with this design, and Zhai Liangpeng and Weng Xinyuan also recorded them. After the test was completed, the car returned to the base and told no one to get close to it.

In order to prevent the car's ECU from being stolen, the computer module was removed from the cab. To keep it secret, the car was parked next to the security booth.

Wang Shi and Zhai Liangpeng returned to the computer department, and they began to optimize the coding in the program based on the results of the test.

"You also need to build the computer diagnosis system I just mentioned as soon as possible." Wang Shi went back after explaining the matter.

Wang Shi's next work is mainly to apply for national and international patents.

Domestic ones are easy, mainly because of this international patent, but they are easy to deal with.

However, the state also provided a lot of help.

It is not easy for a domestic patent to apply for an international patent, and it is the automobile industry with the weakest domestic industry. The country should fight for the enterprise, and it is also a kind of publicity.

Applying for an international patent is also troublesome, and with the help of the state, Wang Shi only needs to prepare the finished product.

The World Intellectual Property Organization, referred to as "wipo", is a specialized agency of the United Nations for the protection of intellectual property rights. It was established according to the "Convention Establishing the World Intellectual Property Organization". The Convention was signed in Stockholm, the capital of Sweden, on July 14, 1967, and was signed in April 1970.

It came into effect on June 26. Our country joined the organization on June 3, 1980.

Soon the World Intellectual Property Organization sent people to Tang Dynasty Power Company to personally review the finished product.

There are two finished products, one is a separate engine and the other is installed on the heavy truck.

After expert review, the results were obtained and a patent certificate was issued.

"It is reported that the high-pressure common rail system is the most cutting-edge diesel engine technology. It is the latest product after the traditional camshaft high-pressure oil pump. It has the characteristics of low noise, low oil pump and low pollution emissions. Tang Dynasty Power Company is committed to developing the best

Diesel engine, insisting on technological innovation, the national leader in high-pressure common rail system

The yield rate has reached 98%, and there are many national patents, which are patents jointly developed by Tang Dynasty Power Company and Xi'an University of Electronic Science and Technology..." The news was broadcast on Xinwen Lianbo at 7:30 that night,

In the end, Wang Shi had a few seconds of opportunity to appear on camera. It was a video of a reporter interviewing Wang Shi.
