Chapter 253: Technology is intimidating
SAIC, Lingang Automobile Manufacturing Base, FK-30 Engine R&D Center.
Meng Xiaobai brought Guan Yang, Xie Lingbo and others to visit, the purpose was to find out the cause of the FK-30 engine burst.
"I have analyzed the cause of the failure very clearly, it is your crankshaft problem, you don't need to look at it again!" said Buck Green firmly at the scene.
"Mr. Meng, although I also attach great importance to the cooperation with Bluestar Automobile, the engine problem is not a trivial matter. If you can't come up with a solution, we may want to consider changing suppliers. Du Zhen said solemnly.
Meng Xiaobai didn't answer directly, but asked: "There is news in the industry today that there is a problem in our crankshaft manufacturing, which caused your engine to burst, does Mr. Du know about this?"
Du Zhen shook his head, "I don't know, but I promise, it's definitely not from within our group." We don't do anything like this that would affect your company's reputation. ”
"I believe in your company too. Of course, Meng Xiaobai knew who did it, and he said: "After we solve the problem today, I hope your company will issue an announcement to clarify." ”
"This is natural!" Du Zhen agreed, compared to this, he was more concerned about the engine.
Meng Xiaobai looked at Buck Green again and asked, "Mr. Green, I have read all the conclusions of your analysis. ”
Everyone looked at Meng Xiaobai, could it be that this boss of deep space technology still understands automobile engines? This is impossible, right? It is rumored that Meng Xiaobai is an IT genius, and it is unlikely that he understands mechanical knowledge. Not to mention the most professional and top-level automotive core technology engine technology.
"I think you're completely ......" Meng Xiaobai paused for a moment and added, "Nonsense!"
"Huh?" The people at SAIC didn't expect Meng Xiaobai to comment like this at all, and they were immediately stunned for a moment.
Buck Green thought that Meng Xiaobai wanted 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!"
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 is also a little angry, this Meng Xiaobai is too faceless, right? You know, no matter how you say that the engine burst, it is the fault of Bluestar Automobile!
Don't talk about them, Guan Yang, Xie Lingbo and the others were shocked, they couldn't imagine that Meng Xiaobai would say this in front of people.
"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 failure of the FK-30 engine was not the cause of the crankshaft at all, but the problem with the engine block he designed!"
"What?" Buck Green was even more angry, his face turned red, and he said to Du Zhen: "Mr. Du, you have heard it, he is insulting me and slandering me! He must apologize to me, otherwise I will find a lawyer to sue him!"
"Mr. Meng, isn't it okay for you to be like this?" Du Zhen said in a deep voice.
"You don't believe it?" Meng Xiaobai said.
"There is no evidence, you said that it was the reason for the cylinder, so you also need a reason!" Guo Ping asked.
"Okay!" Meng Xiaobai said: "Buck Green, don't be busy suing me first, wait for me to find out the problem for you, and then you can think about it carefully." What about samples and data sheets for the FK-30 engine?
"It's in the workshop!" Guo Ping pointed to the engine in the workshop, including the sample and the one that burst the cylinder.
"Mr. Meng can look at it casually and see what the problem is, just say!" Guo Ping also held his breath in his heart, this Meng Xiaobai was too arrogant and didn't take them designers seriously. Each of them is an elite, and it took years to design this engine, and the cause of the failure has been repeatedly analyzed and demonstrated, and it is absolutely impossible to be something else!
Meng Xiaobai checked the data and physical objects again, and said: "At that time, the engine burst the cylinder, whether it happened because of the rupture of the cylinder wall. ”
"Yes. Guo Ping said.
"It's because the crankshaft is not properly designed, which leads to too much side thrust, and the friction against the cylinder wall causes high temperatures to detonate!" Buck Green said immediately.
A group of designers nodded their heads, and they all agreed with this statement.
"!" Meng Xiaobai pointed to the engine cylinder wall and said: "The design of the crankshaft is unreasonable? You take a closer look, what is wrong with the size and performance of the crankshaft? It's inevitable that the piston will rub against the cylinder wall, but if you offset the piston and crankshaft a little bit, the friction will be greatly reduced. ”
"According to the data, it can definitely run stably for a long time!"
Meng Xiaobai was not arguing in vain, 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, when the crankshaft and piston are offset to a certain position, the side thrust is greatly reduced, and the corresponding coefficient of friction is also reduced.
"This ...... Seems to make some sense. Duan Rong saw the video and thought thoughtfully.
"That's just one aspect, I just checked your cylinder materials. Some of your engine blocks are made of magnesium alloy, right?" Meng Xiaobai said, everyone nodded, and Guo Ping said: "It is true that magnesium alloy is used in some parts of the cylinder block, which is to make the engine lighter. ”
"There is nothing wrong with using magnesium alloy to lighten 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 flaw is poor corrosion resistance, easy oxidation combustion, 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, it can not only reduce the weight of the engine, but also avoid the shortcomings of magnesium alloys. It's a pity that you guys just have a design problem!"
"You...... You're talking nonsense!" Buck Green was a little weak-hearted.
"Really, how about looking at my modification plan?" Meng Xiaobai gestured to Xie Lingbo, Xie Lingbo immediately showed the next video, and explained: "This is our total Meng's modified engine block design and material ratio, through the modification of the cylinder design, not only did not increase the engine mass, but used magnesium aluminum alloy to reduce the engine mass by five percent again, and the performance was better than before!"
"In the simulation test, there was not a single problem. ”
A group of designers found that in the video, the design of the cylinder block was really different, Guo Ping immediately shook his body, and exclaimed: "Why didn't I think of it?
"Yes! The materials and design of the combustion chamber have been modified...... This may be really possible!"
"I have a gut feeling that this design is better than the previous ones!" began the designers, who were all too familiar with the FK-30 engine.
It's like a group of top students solving Olympiad problems, just tell them an idea, and they will immediately find a solution by themselves.
When Buck Green saw the video, he was even more shocked, decades of experience in automobile 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 FK-30 cylinder explosion!" Meng Xiaobai didn't finish speaking, "That's the problem of the wear-resistant coating of the cylinder wall!"
"Turbocharged engines have much more torque than self-aspirated, and the friction-reducing effect of the lubricant does not prevent the friction of the cylinder and piston walls from heating up. Your cylinder walls are not coated with the increased engine torque of the turbine!"
"This ......" Guo Ping was speechless by him, and he also knew this problem in his heart. The wear-resistant coating of this FK-30 engine has not improved in materials, if it is a self-aspirated engine, it is fine, but this is an engine with an added turbocharger, and the original material cannot meet the needs of use!
"It seems, that's the truth!" Duan Rong felt a little suddenly realized, before Buck Green said that it was the crankshaft, he always felt that it was wrong, but he couldn't find a problem.
Now, after Meng Xiaobai's explanation, he found that this seems to be the case! The design and material problems of the engine block led to the occurrence of the cylinder explosion accident!
"I said it was wrong, it turned out to be a cylinder block design problem!" One designer has already started to use computer software simulation, "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 Bluestar, but he had thought in the wrong direction in the first place.
Now after listening to Meng Xiaobai's words and seeing his revised design plan, Buck Green already knows in his heart that this time, it is indeed his own mistake, and it is a big mistake!
Although Du Zhen didn't understand it very well, when he saw the designers like this, he also knew in his heart that Meng Xiaobai really didn't deliberately say big things!
He was secretly shocked in his heart, this boss of deep space technology really knows 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 this?
"Xiao Xie, Mr. Meng studied mechanical design before?" Guan Yang couldn't help but ask Xie Lingbo.
"No, he studied computers. Xie Lingbo looked puzzled.
"He knows too much to ...... Oh, it must be Dr. Kaneki!" Guan Yang made an excuse for himself, these must have been told by Dr. Kaneki to Mr. Meng, otherwise how could Mr. Meng know so much?
Thinking of this, Guan Yang's heart is much more balanced, otherwise this boss is young, and his professional skills are better than him, so he won't 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 he would be slapped in the face by someone else in the field he was best at today, and he was beaten without any power to fight back!
"Alright. As long as the problem is clear, it will be easy to do. Du Zhen hurriedly relieved Buck Green and said: "This matter is indeed our fault, and we misunderstood you without investigating the cause of the failure." I am here, on behalf of our company, to apologize to Mr. Meng and all of you at Bluestar Automobile!"
"No, just solve the misunderstanding. Meng Xiaobai didn't plan to worry about it anymore, speaking of which, the other party was still their big customer.
That night, Du Zhen held a banquet to entertain everyone in Bluestar Automobile and apologized.
At the banquet, Du Zhen asked: "Mr. Meng, I don't know if your company can supply the engine block you showed today?"
"Of course you can!" Meng Xiaobai waited for him to say this, and he spent his time revising the design plan in order to sell products.
"That's great! I think we can sign a new supply contract, and the Bluestar Automobile Factory will provide us with the blocks for the FK-30 engines!" Du Zhen said happily. Guo Ping just told him that Meng Xiaobai's design plan is wonderful, but it is difficult for them to manufacture, so in the end, they still have to find Bluestar Motors.
"Then I wish our cooperation in advance!" Meng Xiaobai raised his glass.
"The cooperation went well!"
At the end of the banquet, Guan Yang also deliberately found Meng Xiaobai and said: "Mr. Meng, you just promised them to manufacture the cylinder block, but I read the design requirements, but I'm afraid that we can't make it now." ”
"It's alright, I've already instructed Dr. Kaneki to revamp our finale. Meng Xiaobai said.
"Can the finale be transformed?" Guan Yang was stunned, how much hidden scientific and technological strength does deep space technology have?
