Meng Xiaobai brought Guan Yang, Xie Lingbo and others to visit, with the purpose of finding out the cause of the fk-30 engine cylinder explosion.
"I have analyzed the cause of the failure very clearly. It is your crankshaft problem. There is no need to look further!" Buck Green said firmly at the scene.
"Mr. Meng, although I also attach great importance to cooperation with Blue Star Motors, the engine problem is not a trivial matter. If you cannot provide a solution, we may have to consider changing suppliers." Du Zhen said seriously.
Meng Xiaobai did not answer directly, but asked: "Today there was news in the industry that there was 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 guarantee that it definitely did not come from within our group. We will not do anything like this that will affect your company's reputation."
"I also believe in your company." Meng Xiaobai certainly knew who did it. He said, "After we have solved the problem today, I hope your company will issue an announcement to clarify it."
"This is natural!" Du Zhen agreed. Compared with this, he was more concerned about the engine problem.
Meng Xiaobai looked at Buck Green again and asked: "Mr. Green, I have read all your analysis and conclusions."
Everyone looked at Meng Xiaobai. Could it be that the CEO of Deep Space Technology actually knew about car engines? Isn't that impossible? It was rumored that Meng Xiaobai was an IT genius and it was unlikely that he knew anything about mechanics. What's more, he was the most professional and most knowledgeable person.
Top automotive core technology engine technology.
"I think you are completely..." Meng Xiaobai paused and added: "Nonsense!"
"Ah?" Everyone at SAIC didn't expect Meng Xiaobai to comment like this, and they were stunned for a moment.
Buck Green thought Meng Xiaobai wanted to say something to defend him, but he didn't expect that he would open his mouth to accuse himself. He immediately became angry and shouted: "Mr. Meng, you are insulting me! You are insulting my personality and professionalism!"
Chief Engineer Guo Ping was also dissatisfied and said: "Mr. Meng, what do you mean by this? Do you think we are all lying to you?"
Du Zhen was also a little angry. Isn't this Meng Xiaobai too disrespectful? You know, the engine explosion is the fault of Blue Star Motors!
Not to mention them, Guan Yang, Xie Lingbo and others were all shocked. They didn't expect Meng Xiaobai to say this in front of others.
"Don't worry." Meng Xiaobai smiled slightly and said confidently: "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! The fk-30 engine explosion is simply a matter of fact.
It’s not the crankshaft, but the engine block he designed that has a problem!”
"What?" Buck Green became even more angry. He blushed and said to Du Zhen: "Mr. Du, you heard it. He just insulted me and slandered me! He must apologize to me, otherwise I will find a lawyer.
Sue him!"
"Mr. Meng, isn't it good for you to be like this?" Du Zhen said in a deep voice.
"You don't believe it?" Meng Xiaobai said.
"It's all nonsense. You said it was the cylinder, but you still need a reason!" Guo Ping asked.
"Okay!" Meng Xiaobai said: "Buck Green, don't rush to sue me. Wait until I find out the problem for you, and then you can think about it carefully. Where are the samples and data sheets of the FK-30 engine? Give them to me!"
"It's in the workshop!" Guo Ping pointed to the engines in the workshop, including the sample and the one with a blown cylinder.
"Mr. Meng, you can take a look at it as you like. If you see any problems, just say it!" Guo Ping also held his breath in his heart. This Meng Xiaobai is too arrogant and does not take designers like them seriously. Each of them is an elite and has spent a lot of money.
It took several years to design this engine, and the cause of the failure has been repeatedly analyzed and demonstrated. It is absolutely impossible to be other problems!
Meng Xiaobai checked the data and the actual object again and said: "The engine exploded at that time. Was it because of the cylinder wall rupture?"
"Yes." Guo Ping said.
"It's because the crankshaft design is unreasonable, resulting in too much side thrust, causing high temperature and explosion due to friction with the cylinder wall!" Buck Green said immediately.
All the designers nodded, they all agreed with this statement.
"Bullshit!" Meng Xiaobai pointed at the engine cylinder wall and said: "The design of the crankshaft is unreasonable? Take a closer look. Is there anything wrong with the size and performance of the crankshaft? It's just that you have placed the crankshaft in the wrong position. The piston rubs against the cylinder wall.
Of course, but if you offset the piston and the crankshaft a little bit, you'll reduce friction significantly."
“According to data calculations, it can definitely run stably for a long time!”
Meng Xiaobai was not arguing in vain. He had already prepared a computer simulation video. As he was talking, Xie Lingbo connected to the computer screen in the workshop and showed it to them.
Sure enough, after the crankshaft and piston are offset 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 looked thoughtful after seeing the video.
"This is just one aspect. I just checked your cylinder block material. Your engine block, part of it is made of magnesium alloy, right?" Meng Xiaobai said, everyone nodded, Guo Ping said: "It is indeed used in some parts of the cylinder block.
Magnesium alloy is used to make the engine lighter."
"There is nothing wrong with using magnesium alloy to make engines lighter. 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 has poor corrosion resistance, is easy to oxidize and burn, and has poor heat resistance. Therefore, most engine blocks are 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 alloy can be avoided. Unfortunately, you just have a design problem!"
"You...you're talking nonsense!" Buck Green felt a little guilty.
"Really? What about my modification plan?" Meng Xiaobai gestured to Xie Lingbo, who immediately showed the next video and explained: "This is the engine cylinder design and material ratio modified by our Mr. Meng. Through the cylinder
The modification of the body design not only did not increase the engine mass, but used magnesium-aluminum alloy to reduce the engine mass again by 5%, and the performance is even better than before!"
"During the simulation test, there was not a single problem."
A group of designers discovered that the cylinder design in the video was indeed different. Guo Ping was immediately shocked and exclaimed: "Why didn't I think of that? These points have been changed so well!"
"Yes! Modifications to the materials and design of the combustion chamber... this may be possible!"
"I have an intuition that this design is better than the previous one!" The designers started talking, and they were all too familiar with the FK-30 engine.
It's like a group of top students solving Mathematical Olympiad problems. Just tell them an idea and they can find the solution immediately.
Buck Green was even more horrified when he saw the video. Decades of experience in automotive engine design told him that this design was several times better than his!
"In addition to the design, there is another fatal factor in the explosion of the fk-30 cylinder!" Meng Xiaobai has not finished speaking, "That is the problem of the wear-resistant coating on the cylinder wall!"
"The torque of a turbocharged engine is much greater than that of a self-aspirated engine. The friction reduction effect of the lubricant cannot avoid the friction and heating of the cylinder wall and piston wall. Your cylinder wall wear-resistant coating cannot cope with the increased pressure of the turbine.
Engine torque!”
"This..." Guo Ping was speechless by what he said. He also knew this problem in his heart. The wear-resistant coating of this fk-30 engine has not made any material progress. It would be okay if it was a self-aspirated engine, but
This is an engine with a turbocharger added, and the original materials can no longer meet the needs!
"It seems like this is the truth!" Duan Rong felt a little enlightened. Buck Green said before that it was the crankshaft, but he always felt something was wrong, but he couldn't find the problem.
Now after Meng Xiaobai explained it, he found that it seemed to be true! The design and material problems of the engine cylinder led to the cylinder explosion accident!
"I said something doesn't feel right. It turns out it's a cylinder design problem!" A designer has already started to simulate using 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 mean to slander Blue Star Motors, but he was thinking 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, when he saw the designers looking like this, he understood in his heart that Meng Xiaobai did not deliberately lie!
He was secretly shocked. Did the CEO of Deep Space Technology really know more than their top designers? Or did he do his homework in advance? He should have done his homework in advance, otherwise how could he understand?
These?
"Xiao Xie, did Mr. Meng study mechanical design before?" Guan Yang couldn't help but ask Xie Lingbo.
"No, he studies computer science." Xie Lingbo looked confused.
"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 these things, otherwise how could Mr. Meng know so much?
?
Thinking of this, Guan Yang felt much more balanced in his heart. Otherwise, this boss was young and had better professional skills than him. How could he be allowed to live?
"What, Mr. Buck Green, are you still planning to sue me?" Meng Xiaobai looked at Buck Green.
Buck Green was extremely embarrassed. He never thought that he would be slapped in the face today by someone in the field where he is best at, and he was beaten without the ability to fight back!
"Okay. As long as the problem is clearly identified, it will be easy to solve." Du Zhen quickly came to Buck Green's rescue and said: "This matter is indeed our fault. We misunderstood you without investigating the cause of the fault. I am here,
On behalf of our company, we apologize to Mr. Meng and everyone at Blue Star Motors!"
"No need, just clear up the minor misunderstanding." Meng Xiaobai didn't intend to argue anymore. After all, the other party was still their big customer.
That night, Du Zhen hosted a banquet for everyone at 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 was waiting for him to say this, and spent his time modifying the design plan just to sell the product.
"That's great! I think we can sign a new supply contract, and Blue Star Automobile Manufacturing Plant will provide us with fk-30 engine cylinder blocks!" Du Zhen said happily. Guo Ping just told him that Meng Xiaobai's design plan
It's wonderful, but they are difficult to manufacture, so in the end we still have to find Blue Star Motors.
"Then I wish our cooperation in advance good luck!" Meng Xiaobai raised his glass.
“Good cooperation!”
After the banquet was over, Guan Yang went to Meng Xiaobai and said, "Mr. Meng, you just promised them to make the cylinder, but I saw the design requirements and I'm afraid we can't make it now."
"It's okay, I've already asked Dr. Kaneki to modify our final machine." Meng Xiaobai said.
"Can the final machine be modified?" Guan Yang looked stunned. How much hidden technological strength does deep space technology have?
