Don't give me black technology

Chapter 254
SAIC Group, Lingang Automobile Manufacturing Base, FK-30 Engine R&D Center.

Meng Xiaobai brought Guan Yang, Xie Lingbo and others to visit, the purpose is to find out the reason for the explosion of the FK-30 engine.

"I have already analyzed the cause of the failure very clearly. It is your crankshaft problem. There is no need to look again!" Buck Green said firmly at the scene.

"Mr. Meng, although I also attach great importance to the cooperation with Bluestar Motors, the engine problem is not a trivial matter. If you can't provide a solution, we may have to consider changing suppliers." Du Zhen said seriously.

Meng Xiaobai did not answer directly, but asked: "There is news in the industry today that there is a problem with our crankshaft manufacturing, which caused your engine to explode. Does Mr. Du know about this?"

Du Zhen shook his head, "I don't know about it, but I promise, it's definitely not from within our group. We won't do such a thing that affects your company's reputation."

"I also believe in your company." Of course Meng Xiaobai knew who did it, and he said, "After we have solved the problem today, I hope your company will issue an announcement to clarify."

"Naturally!" Du Zhen readily agreed. Compared with this, he was more concerned about the problem of the engine.

Meng Xiaobai looked at Buck Green again and asked, "Mr. Green, I have read all your analysis conclusions."

Everyone looked at Meng Xiaobai. Could it be that the CEO of Deep Space Technology still knows about car engines?This is impossible, right?It was rumored in the outside world that Meng Xiaobai was an IT genius, and it was unlikely that he knew mechanical knowledge.What's more, it is the most professional and top-level automotive core technology engine technology.

"I think you are totally..." Meng Xiaobai paused, and added: "Nonsense!"

"Ah?" Everyone in SAIC didn't expect Meng Xiaobai to make such an evaluation at all, and they were stunned for a moment.

Buck Green thought that Meng Xiaobai was going to say something to justify, but he didn't expect him to open his mouth to accuse himself. He immediately became angry and said loudly: "Mr. Meng, you are insulting me! You are insulting my personality and professionalism!"

The chief engineer, Guo Ping, was also dissatisfied, and said, "Mr. Meng, what do you mean by that? Don't you think we are all lying to you?"

Du Zhen was also a little angry. Isn't this Meng Xiaobai too shameless?You know, the engine explosion is the fault of Blue Star Motors!
Not to mention them, Guan Yang, Xie Lingbo and the others were shocked, they never thought that Meng Xiaobai would say that in front of a human being.

"Don't worry." Meng Xiaobai smiled and said to himself: "I didn't mean to insult you, I was just seeking truth from facts. As for questioning Mr. Buck Green's professionalism, this is true! FK-30 engine explosion It's not the crankshaft, it's a problem with the engine block he designed!"

"What?" Buck Green became even more angry. He blushed and said to Du Zhen: "Mr. Du, you heard it all, he just insulted me and slandered me! He must apologize to me, or I will find a lawyer Sue him!"

"Mr. Meng, isn't it good for you?" Du Zhen said in a deep voice.

"You don't believe it?" Meng Xiaobai said.

"It's empty talk. If you say it's the tank, you need a reason anyway!" Guo Ping asked.

"Okay!" Meng Xiaobai said: "Buck Green, don't rush to sue me, wait for me to find out the problem for you, and then think about it carefully. Where are the samples and data sheets of the FK-30 engine? Give it to me!"

"It's in the workshop!" Guo Ping pointed to the engines in the workshop, including the sample and the one with the blown cylinder.

"Mr. Meng can look at it casually, and if he sees any problems, just say it!" Guo Ping also held his breath in his heart. This Meng Xiaobai is too arrogant, and he doesn't take designers like them seriously.Each of them is an elite. It took several years to design this engine, and the cause of the failure has been analyzed and demonstrated repeatedly. It is absolutely impossible to be other problems!
Meng Xiaobai checked the data and reality again, and said, "The engine exploded at that time, did it happen because of the rupture of the cylinder wall?"

"Yes." Guo Ping said.

"It is because of the unreasonable design of the crankshaft that the side thrust is too large, and the friction with the cylinder wall causes high temperature and detonation!" Buck Green said immediately.

All the designers nodded, and they all agreed with this statement.

"Nonsense!" Meng Xiaobai pointed to the cylinder wall of the engine and said, "The design of the crankshaft is unreasonable? Take a closer look, what's wrong with the size and performance of the crankshaft? It's because you misplaced the crankshaft. The piston rubs against the cylinder wall. Definitely, but if you offset the piston and the crankshaft a little bit, it reduces friction a lot."

"According to the data calculation, it can definitely run stably for a long time!"

Meng Xiaobai was not just talking about it, he had already prepared a computer simulation video, and while he was talking, Xie Lingbo connected to the computer screen in the workshop and showed it to them.

Sure enough, after the position of the crankshaft and the piston is biased to a certain position, the side thrust will be greatly reduced, and the corresponding friction coefficient will also be reduced.

"This... seems to make sense." Duan Rong saw the video thoughtfully.

"This is just one aspect. I checked your cylinder block material just now. Your engine block is partially made of magnesium alloy, right?" Meng Xiaobai said, everyone nodded, Guo Ping said: "It is true that some parts of the cylinder block use Magnesium alloy is used to make the engine lighter."

"It's not wrong to use magnesium alloy to reduce the weight of the engine. Magnesium alloy has low density, strong shock absorption performance, good electrical conductivity, and good process performance." Meng Xiaobai first affirmed their approach, and then said: "But its most fatal shortcoming It is poor corrosion resistance, easy to oxidize and burn, and poor heat resistance. Therefore, most of the engine block is still made of aluminum alloy or magnesium aluminum alloy."

"As long as the design is good, the weight of the engine can be reduced, and the shortcomings of magnesium alloys can also be avoided. Unfortunately, you have a problem with the design!"

"You...you're talking nonsense!" Buck Green felt a little guilty.

"Really? Then how about my modification plan?" Meng Xiaobai motioned to Xie Lingbo, Xie Lingbo immediately showed the next video, and explained: "This is our modified engine block design and material ratio by Mr. Meng. The modification of the body design not only did not increase the engine mass, but also reduced the engine mass by 5.00% by using magnesium-aluminum alloy, and the performance is even better than before!"

"During the simulation test, there was never a single problem."

A group of designers discovered that in the video, the design of the cylinder block was really different. Guo Ping was shocked immediately and exclaimed: "Why didn't I think of it? These changes are great!"

"Yeah! The material and design modification of the combustion chamber... this, maybe it's really possible!"

"I have an intuition that this design is better than the previous one!" The designers talked one after another, and they were all too familiar with the FK-30 engine.

It's like a group of top students solving Olympiad problems, as long as you tell them an idea, they can find the solution immediately.

When Buck Green saw the video, he was even more horrified. Decades of experience in automotive engine design told him that this design was several times better than his own!
"In addition to the design, there is another fatal factor for the FK-30 cylinder explosion!" Meng Xiaobai hadn't finished speaking, "That is the problem of the wear-resistant coating on the cylinder wall!"

"Turbocharged engine torque is much greater than that of self-breathing, and the friction reduction effect of the lubricant cannot avoid the frictional heating of the cylinder wall and piston wall. Your cylinder wall wear-resistant coating cannot cope with the increased pressure of the turbo. Engine torque!"

"This..." Guo Ping was left speechless by what he said, and he knew the problem in his heart.The wear-resistant coating of this FK-30 engine has not made any material progress. If it is a self-aspirated engine, it is okay, but this is an engine with a turbocharger added, and the original materials cannot meet the needs of use!

"It seems that this is the reason!" Duan Rong felt a little bit suddenly realized. Before Buck Green said that it was the crankshaft, he always felt that it was wrong, but he couldn't find the problem.

Now after Meng Xiaobai's explanation, he found that it seemed to be true!The design and material problems of the engine cylinder block led to the occurrence of cylinder explosion accidents!

"Why do I think it's wrong? It turned out to be a problem with the design of the cylinder block!" A designer had already started to simulate with computer software. "If the data is corrected, the engine can indeed run in a steady state!"

"How could this be?" Buck Green was sweating profusely. He didn't intend to slander Blue Star Motors, but he thought in the wrong direction from the beginning.

Now after listening to Meng Xiaobai's words and seeing his revised design plan, Buck Green already knew in his heart that this time, he was indeed wrong, and it was a big mistake!
Although Du Zhen didn't understand it very well, seeing the appearance of the designers, he knew in his heart that Meng Xiaobai did not deliberately speak big words!

He was secretly shocked, the boss of Deep Space Technology really knows better than their top designer?Or, did he do his homework in advance?He should have done his homework in advance, otherwise how could he understand this?
"Xiao Xie, Mr. Meng has studied mechanical design before?" Guan Yang couldn't help asking Xie Lingbo.

"No, he studied computer." Xie Lingbo looked puzzled.

"He knows too much, it's impossible...oh, it must be Dr. Jinmu!" Guan Yang made an excuse for himself, Dr. Jinmu must have told Mr. Meng, otherwise how could Mr. Meng know so much ?

Thinking of this, Guan Yang felt much more balanced in his heart. Otherwise, this boss is young and has better professional skills than him, so why would he let people live?
"What, Mr. Buck Green, are you still going to sue me?" Meng Xiaobai looked at Buck Green.

Buck Green was extremely embarrassed. He never thought that today he would be slapped in the face by others in his best field, and he was so slapped that he had no power to fight back!
"Okay. As long as the problem is clearly identified, it will be easy to handle." Du Zhen quickly rescued Buck Green and said, "It is indeed our fault. We misunderstood you without investigating the cause of the failure. I am here, On behalf of our company, I would like to apologize to Mr. Meng and everyone at Bluestar Motors!"

"No need, it's just a small misunderstanding." Meng Xiaobai didn't plan to worry about it anymore, since the other party was still their big client.

That night, Du Zhen held a banquet in honor of everyone from Blue Star Motors and apologized.

At the banquet, Du Zhen asked: "Mr. Meng, I wonder if your company can supply the engine block you showed today?"

"Of course!" Meng Xiaobai waited for him to say this, and he spent all his time modifying the design plan to sell the product.

"That's great! I think we can sign a new supply contract, and the Blue Star Automobile Factory will provide us with the cylinder block of the FK-30 engine!" Du Zhen said happily.Guo Ping told him just now that Meng Xiaobai's design plan is wonderful, but they are very difficult to manufacture, so in the end they still have to find Blue Star Motors.

"Then wish us a smooth cooperation in advance!" Meng Xiaobai raised his glass.

"Smooth cooperation!"

After the banquet was over, Guan Yang found Meng Xiaobai on purpose, and said, "Mr. Meng, you promised them to make the cylinder block just now, but I read the design requirements, and I'm afraid we won't be able to make it now."

"It's okay, I have ordered Dr. Kaneki to modify our die-casting machine." Meng Xiaobai said.

"Can the die-casting machine be transformed?" Guan Yang was stunned. How much hidden technological strength does Deep Space Technology have?
