Rebirth of the Auto Giant

Chapter 570 Development Progress of New Engines

Marry a wife who is virtuous, virtuous and talented.

The first is to be gentle and kind. A gentle woman often has a harmonious tutor. She can control her emotions at any time. When a husband and wife quarrel, a virtuous wife will give in to each other and reduce the number of quarrels between the two.

They argue over trivial matters and strive to make a difference.

A gentle and kind woman can resolve family disputes.

The second is to be sensible and filial. A sensible woman is a good wife to her husband. The man works hard outside to make money to support the family, and the woman takes good care of her children at home. Such a woman will make men feel particularly worry-free. For men,

She is a good wife and a good daughter-in-law to her parents-in-law.

Being a daughter-in-law is difficult, but if the woman is more filial, there won't be many conflicts between mother-in-law and daughter-in-law, and the family will become more harmonious.

Zhao Min is such a person.

Wang Shi was particularly grateful for this.

If it were other women, when they find out that their husband has a woman outside, they will cry, make fuss, and hang themselves, which makes the chickens and dogs uneasy. In the end, both parties are cornered, and the only option is divorce.

"Wife, you are so good to me that I feel guilty." Wang Shi gratefully kissed his wife on the forehead and said.

"This will never happen again." Zhao Min glared at her husband and said.

"I swear, there will never be a next time." Wang Shi raised his hand and swore.

"Hey, your men's oaths are just like those in TV commercials. They are not very credible."

"No more, next time I go on a business trip, I will take you to meet Li Yue." Wang Shi said.

"Li Yue, what a good name, what does it do?"

"She is a flight attendant. I often fly on business trips. I met her on the plane. She is a very nice person. Like you, she must be kind-hearted and always considerate of others..." Wang Shi told his wife about Li Yue's situation.

Wang Shi has always had nothing to hide from his wife. If he doesn't want the two of them to live in the same bed and have different dreams, it would be boring to live. If it's okay or not, tell them all and find a solution instead of hiding it in their hearts. The husband and wife are suspicious of each other.

"Okay, she must be very beautiful, otherwise she wouldn't be able to seduce my husband."

"It's so ugly to talk about seducing. It's me who takes the initiative to pick up people."

"Did you spend money on it?"

"Your husband is so handsome, does he need to spend money on him? He must be impressed by my charm."

The couple chatted and slowly fell asleep.

Li Yue has now been transferred to work at the ground ticket office. She is not busy at work and does not have to fly everywhere every day like before.

Work on the ground and commute to get off work on time.

The next day, the couple came to the company.

Now that he was forgiven, Wang Shi felt lighter.

I came to the R&D center of the company's technical department to check the development progress of gasoline EFI engines.

Gasoline EFI engines are based on diesel EFI technology.

The electronic control unit has also been modified accordingly based on the original diesel electronic control unit.

Gasoline engines are different from diesel engines. Diesel engines use compression ignition. Since the auto-ignition temperature of diesel is relatively low, only about 220 degrees Celsius, and its viscosity is high and difficult to evaporate, diesel engines have no spark plugs and have a larger compression ratio than gasoline engines.

Therefore, relying on the compression stroke, the mixture can be compressed to the ignition point, allowing it to automatically ignite in the cylinder, so the compression ratio of diesel engines is higher than that of gasoline engines.

Gasoline engines, because gasoline has a lower ignition point than diesel, are easier to ignite, and have a lower compression ratio than diesel engines. The auto-ignition temperature of gasoline is much higher, around 480 degrees Celsius, has low viscosity and is easy to evaporate. Therefore, it is necessary to mix the oil and gas ratio in advance or use the injection system

Gasoline is directly injected into the cylinder, and then a spark plug is used to ignite the mixture at the end of the compression stroke. When the piston reaches the top dead center of the compression stroke, the huge thrust generated by the explosion of the mixture causes the piston to continue to move downward.

The work stroke begins.

Gasoline engines also have their advantages over diesel engines, including lower noise, less pollution, and lower vibration.

Before the emergence of electronic injection machines, the atomization of gasoline engines mainly relied on mechanical carburetors.

The atomization effect is not good.

Tang Dynasty’s EFI technology patent has always been in its own hands.

A total of four gasoline engines with different displacements have been developed: 1.6, 1.8, 2.0, and tc3.8v6.

tc3.8v6 is an engine specially used in the future Kunpeng sports car series sports cars.

The body uses an aluminum alloy cylinder block and head.

"How is the progress?" Wang Shi saw that there were many finished auto parts, cylinders, pistons, piston rings, connecting rods, various tiles, screws, etc. in the technical dust-free workshop.

"This is the first prototype. We are preparing to assemble it and try it out." Technical director Gao Mingyuan and veteran technician Xing Lichong said in unison.

"We must make every product upgrade a breakthrough in processing technology and installation technology. Our company's engines are the core. We want users to know that car engines are the first to think of us. We must do this

First of all, as the company's technical researchers, you must have the feelings of a painter, treat the products as your own masterpieces, and draw the most beautiful and beautiful works in your heart."

“It’s okay if we didn’t have high-precision CNC machine tools in the past. Now that we have such high-precision CNC machine tools, we need to make breakthroughs in the matching clearance of the engine.”

"For an engine, if the parts difference drops from plus or minus 0.24 to 0.18, the engine's power can be increased by 0.7%, and the corresponding fuel consumption can be reduced by 0.5%. To achieve this, we all need to continue to explore

, keep learning." Wang Shi looked at it for a while, and then said: "In this regard, little rb has done a very good job. We have to admit that in order to learn from each other's strengths, I think craftsmanship is very accurate.

"

"Craftsmen must strive for excellence and constantly break through themselves. Only in this way can our products continue to develop and progress. Otherwise, we will always stand still and one day be eliminated by the market."

After Gao Mingyuan heard Wang Shi's words, he continued: "The chairman's words are very correct. In fact, we have thought of this a long time ago and implemented it in our work. Previously, we allocated funds to the company and developed a batch of torque automation tools in universities.

The equipment has now been successfully developed, so

Yes." Gao Mingyuan pointed to a batch of automatic torque electric equipment in the dust-free assembly workshop, "These equipment are computer-controlled, and the core parts of the engine such as cylinder head screws, connecting rod screws, and camshafts are all automatically controlled and discarded.

It has replaced the original manual operation method in the past.”

"Oh, this is the plan I proposed last time, developed?" Wang Shi proposed a production plan for automated production and precision processing in two years.

Then a sum of money was allocated to the technology department to carry out equipment upgrade and research and development work.

"Yes, this is an automated engine installation equipment jointly developed by the university and the company's computer department. The torques here can be debugged by computer, and can be debugged accordingly according to the screw torques of different parts. Also, some major engine cores

The components, we use the cold installation method, below zero..." Gao Mingyuan then installed various parts that were tested by the technology research and development center at several degrees below zero to achieve the best fit gap.

This takes advantage of the principle of thermal expansion and contraction of parts.

"To do this, it requires scientific verification. You must be very familiar with materials science and processing technology. You must know how much the temperature of the processed parts expands under the normal working condition of the engine, what is the gap at normal temperature, and how much the cooling is below zero.

How much degree and how much cold shrinkage gap can achieve the best effect of the fitting of the accessories, and the order of installation of each part also has strict requirements." Gao Mingyuan said.

"Well, the principle of the engine has been changing from the time it was invented to today. Everyone knows that it uses the heat energy generated by the fuel explosion to convert the kinetic energy of the car forward. It is all four strokes. Why do some companies manufacture

The engine has low vibration, low noise and high power?”

"In the final analysis, it is a matter of materials and processing technology."

"The material determines the service life of the engine, and the processing technology determines the power of the engine. The smaller the gap and the seamless connection of each part, the lower the energy loss, the higher the utilization rate, and the greater the power." Wang Shi

said.

Then, Wang Shi watched the engineers assemble it.

The whole time takes about half an hour. This is a test. Once the assembly process is fluent and confirmed, the time will be shorter.

"I have only one request. The production volume is based on the premise of technical quality. Our company is taking the road of high-quality products. Unlike other companies that pursue maximizing production and making money, I want users to think of our company as their first impression.

The word "exquisite" is two words."

Wang Shi watched everyone carefully assemble the engine with the help of automated installation equipment, starting with the crankshaft and assembling it in an orderly manner.

The first thing to assemble is the tc3.8v6v engine.

The assembly was completed, the engine oil was filled up, and it was sent to the factory inspection center.

This is a special test platform specially used to test various indicators of the engine. After connecting the exhaust pipe and fuel pipe, everything is ready. Start the engine and the engine will roar.

Various indicators on the instrument panel on one side were beating silently, including engine power, speed, etc.

The old engineer Xing Lichong took a special stethoscope and placed it on both sides of the machine body, the cylinder head and other parts and listened carefully.

The noise on both sides of the engine body is mainly caused by the vibration of the matching clearance of the crankshaft connecting rod system, and the cylinder head is mainly caused by the valves and camshaft.

"The speed of 7,400 rpm, 294 kilowatts and 400 horsepower meets the design standards. In terms of noise, it is a bit louder." Xing Lichong said.

Everyone came outside together.

Wang Shi said: "Other measures can be taken in terms of noise. Starting with the muffler, it can be reduced. Life reliability is the key, especially for sports cars. If something goes wrong every three days or two, then I would rather not do it." Wang Shi said, then

He told Chai Zhenguo from the design department: "After the engine is completed, you will build a concept car to test its functions and at the same time do a publicity campaign." Wang Shi said.

"Okay, it's currently in the design stage, so it may not be that fast," Chai Zhenguo said.

"There is no rush. The engine has not been successful, and its lifespan and reliability have not been tested. There is no rush for the Kunpeng sports car. This is a high-quality product. There is no production requirement. The appearance and driving comfort must be perfect," Wang Shi said.

Finished and left the technology research and development center.

Wang Shi came outside, to the exit of the production workshop, and engines were shipped out one after another and then packed into packaging boxes.

Some are four-cylinder diesel EFI engines for Mantang cars exported to Germany, and some are high-power six-cylinder diesel EFI engines, which are also produced in Germany and are used in Mantang heavy trucks.

The company's scale has expanded several times compared to before, especially after supporting several European companies and manufacturers, it has expanded its production scale.

What we are most indispensable for is people, and with the popularization of compulsory education, the educational level of Chinese people is getting higher and higher, and university graduation is even more common after the expansion of enrollment.

This has also brought benefits to Tang Dynasty Power Company. Except for a small number of newly recruited workers who are taken care of by the family members of old employees, the core positions are all graduates with a bachelor's degree or above.

"Chairman." Wang Shi was wandering around the company compound. Cleaners in Tang Dynasty uniforms were cleaning with brooms. They saw Wang Shi exposed and said hello to Wang Shi.

On the grass on one side, many cleaners were picking weeds on the grass.

"Okay, thank you for your hard work." Wang Shi stopped.

"It's not hard." The other party said gratefully.

"How are you living at home? If you have any difficulties, you can raise them with the company and I will try my best to meet everyone's needs."

"No...no, the salary provided by the company is higher than that of employees in external companies. How can there be still demand? Thank you, Chairman."

The cleaners in the company are generally family members of military personnel in need, and many of them are veterans who have been injured on the battlefield.

"If you have any difficulties at home, just tell me, don't be afraid," Wang Shi said.

"Thank you, Chairman, it's true," the other party said gratefully.

"If your wife is sick and hospitalized, or you have financial difficulties, you must mention it to the company, you know?"

During the years of war, these veteran soldiers were injured and retired for the sake of the nation and the country. Many of them were unable to receive good medical treatment due to financial difficulties due to recurrence of previous injuries on the battlefield.

"Yeah." The other person nodded gratefully.

"If you have anything to do, you can come directly to see me." After Wang Shi said that, he returned to the office.

Back in the office, Wang Shi picked up the phone and called Liu Xingguo, director of the logistics department.

Liu Xingguo put down his work and came to the chairman's office anxiously.

"There is something I need you to do." Wang Shi looked at the other person and said.

"Okay." Liu Xingguo waited seriously for Wang Shi's next order.

"Check it out. Among the company's cleaning staff, their husbands and veteran warriors are sick and hospitalized, so they have financial difficulties. Write a list and give it to me." When Wang Shi asked the employee just now, it was obvious that

He didn't say what he had in mind. After all, in their eyes, he, the richest man in the country, was not the same type of person as them. In their eyes, he was the superior one. Although he was sincere, in their eyes, he was just a

Just a polite word, but don't dare to take it seriously.

We can only ask Liu Xingguo to take action.

"Okay, I'll handle it," Liu Xingguo said.

"There are more than 100 people. This workload is not small. Don't alarm everyone. We need to visit the home."

"Okay." Liu Xingguo also knew that the chairman wanted to give face to the other party. If he gathered everyone and asked them, they would not dare to mention it in front of everyone. It would be different if it was a home visit.

"Go ahead."
