Don't give me black technology

Chapter 252 Unqualified design?
"How could the cylinder explode?" Guo Ping asked anxiously.

"The specific reason is still unclear." Duan Rong, one of the designers, said, "It is under investigation."

The "cylinder explosion" of the engine should be accurately called "cylinder holding", which means that the piston and cylinder barrel of the automobile engine are hugged together and cannot move.The engine may fail, or a thick flame may be emitted.

"Find out quickly!" Guo Ping immediately summoned people to investigate the cause of the FK-30 engine explosion.

A few hours later, the FK-30 engine research team held an emergency meeting to discuss the cause of the engine explosion.

"After investigation, we found that there was a problem with the cylinder block of the engine. There may be collapse and rupture." Duan Rong said.

"It can't be a problem with the cylinder!" A person immediately retorted, "I checked, and there is no problem with the cylinder!"

Everyone looked at him. This was the designer responsible for designing the FK-30 engine block, Buck Green.

This is a Frenchman who used to be an engine designer for British Rover cars.Rover has a long history, founded in 1877, and has produced many high-performance automobile engines.After going through ups and downs, Rover was eventually acquired by a subsidiary of SAIC Motor.

Buck Green also came to SAIC and became an engine designer.Because he has rich experience and is a technical authority, ordinary designers dare not refute him at all, and even the chief engineer Guo Ping has to pay attention to his opinions.

"The cylinder explosion did happen, it cannot explode for no reason, we must find out the problem!" Guo Ping said seriously.

Duan Rong looked at Buck Green, and he said again: "During the inspection, it was found that the engine block was indeed broken."

Hearing this, Buck Green was quite angry. Duan Rong meant that there was a problem with the engine block he designed?
Seeing some designers cast doubtful eyes on him, Buck Green immediately said: "I repeat, the cylinder block I designed has been verified repeatedly, and there is absolutely no possibility of problems!"

"I also saw the inspection report, I think it's not the cylinder block that's faulty, but the crankshaft!"

"Crankshaft? How come?" Guo Ping disagreed, "The quality of the crankshaft this time is very good, and it was ordered from Bluestar Motors."

"It's the crankshaft!" Buck Green insisted that there was something wrong with the crankshaft. He said: "When the mixture in the engine cylinder is burned, the explosive force and pressure will impact the piston. The crankshaft needs to convert the combustion work into effective work, and convert the torque output into piston Side thrust. The side thrust of the piston against the cylinder is unavoidable."

"Generally, there are lubricating oil and wear-resistant coatings to prevent the cylinder from being worn. But if there is a problem with the crankshaft design, the output torque is too large. The piston will rub too quickly and the cylinder will generate high temperature. The cylinder is originally If there is a flammable mixture, there will be a shock explosion in the engine, causing the piston to lock up, and the gas chamber to explode. In summary, there is a problem with the design of the crankshaft. You have adopted an unqualified supplier!"

Buck Green's words were well-founded, and everyone fell into deep thought. Could it be that there is really a problem with the crankshaft?
One person said: "I knew that Blue Star car is unreliable. This crankshaft is not good!"

"Don't make a conclusion too early." Guo Ping was still very puzzled, he always felt that this explanation was still a little bit short of the truth of the engine explosion.

"You can check it again." Buck Green said more and more confidently, "The engine explosion is entirely because the design of the spare parts of Blue Star Motors is not up to standard. I suggest that they be held accountable or change to a new supplier, and put the FK-30 It's so stupid to hand over the future of the engine to a car company that has only been established for two months!"

"Yes, we should ask them clearly!" Other designers also agreed with his point of view.

Buck Green is a senior engine designer. He must be right when he said this. Everyone believes in this former Rover designer.

Guo Ping, Duan Rong and others checked it several times, but still found nothing major, so they could only attribute the explosion to the reason Buck Green said.

"What? There is a problem with the crankshaft we designed? It is unqualified, causing your engine to explode?" Hearing the call from Duan Rong, Guan Yang didn't believe it at all. He immediately retorted: "This is impossible. After it was manufactured, I have personally checked every link, and there will be absolutely no problems!"

"Old Duan, you didn't lie to me, did you? Your engine exploded, it must be something else!"

"The research team has already reached a conclusion that there is a problem with your crankshaft design." Duan Rong said.

"No, no, no, we can't take the blame casually!" Guan Yang still denied that if there was a problem with their design, according to the contract, Bluestar Motors would have to compensate SAIC for a certain amount of losses.

Money is still a small matter, the most important thing is reputation!

Think about it, the first product manufactured by Bluestar Motors had a quality problem. If it gets out, how will the company continue to operate in the future?No one will trust the products they make.

"Our designer Buck Green has clearly written it in the failure analysis report, and I will send it to you later." Duan Rong sighed and said, "Old Guan, I really don't want to see this kind of thing happen. But the engine problem is not a trivial matter, we have invested more than one billion yuan in this project, this responsibility is too great, we must investigate clearly.”

Guan Yang's brows were twisted into the word "Chuan" again, and he said, "I want to read the failure analysis report carefully, and I will reply to you as soon as possible."

"Okay, preferably within three days. Because of this incident, those people above have lost their temper. They are considering holding your company accountable."

After hanging up the phone, Guan Yang immediately reported the matter to Meng Xiaobai.

"There is a problem with our crankshaft?" Meng Xiaobai's first reaction was disbelief, "Is it true? Is it a design or quality problem?"

"They said it was a design problem." Guan Yang said, "The improper design caused excessive friction between the piston and the engine cylinder wall, and the combustible mixture gas impacted the cylinder block, causing the cylinder to explode."

"Design?" Meng Xiaobai was very puzzled. This was designed by Kaneki. Could it be that his design also made mistakes?
"Where's the fault analysis book? Show me." Meng Xiaobai asked him to read the fault analysis book. After studying these days, he can fully understand the relevant knowledge.

"I've already read it. Maybe it's really like this?" Guan Yang's words were a little uneasy. The British designer named Buck Green wrote in an orderly manner, as if there was really a problem with their crankshaft design.

Meng Xiaobai didn't speak, and carefully looked at the fault analysis book. Soon, he slapped the fault analysis book on the desk, and said dissatisfiedly: "Bullshit doesn't make sense, what is this analysis about?"
