"Why did the cylinder explode?" Guo Ping asked anxiously.
"The specific reason is not yet clear." Duan Rong, one of the designers, said, "We are investigating."
Engine "explosion" should be accurately called "cylinder locking", which means that the piston and cylinder barrel of the car engine are hugged together and cannot move. It may cause the engine to be scrapped or emit thick flames.
"Find it out quickly!" Guo Ping immediately summoned people to investigate the cause of the fk-30 engine cylinder 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 engine cylinder. There may be collapse and rupture." Duan Rong said.
"It can't be a problem with the cylinder!" One 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 the engine designer of the British Rover Motors. Rover Motors has a long history. It was founded in 1877 and has manufactured many high-performance automobile engines. After going through ups and downs, Rover Motors was finally acquired by SAIC Group.
Sub-group acquisition.
Buck Green also came to SAIC and became an engine designer. Because he was experienced and technically authoritative, ordinary designers did not dare to refute him. Even chief engineer Guo Ping had to pay attention to his opinions.
"The cylinder explosion did happen. It cannot explode for no reason. We must find the problem!" Guo Ping said seriously.
Duan Rong looked at Buck Green and said again: "During the inspection, it was found that the engine block was indeed cracked."
Hearing this, Buck Green was quite angry. What Duan Rong meant was that there was something wrong with the engine block he designed?
Seeing some designers giving him questioning looks, Buck Green immediately said: "I emphasize again that the cylinder I designed has been repeatedly verified and there is absolutely no possibility of any problems!"
"I also saw the test report. I think the problem is not with the cylinder, but with the crankshaft!"
"Crankshaft? How could it be?" Guo Ping disagreed. "The quality of the crankshaft this time is very good. It was ordered from Blue Star 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 the piston.
Side thrust. The side thrust of the piston rubs against the cylinder, which is unavoidable."
"Generally, there are lubricants and wear-resistant coatings that can prevent the cylinder from being worn. But if there is a problem with the crankshaft design, resulting in excessive output torque, the piston will rub too quickly and the cylinder will generate high temperatures. The cylinder is originally
If there is a combustible mixture, explosion will occur in the engine, causing the piston to lock and the gas chamber to explode. In summary, there is a problem with the design of the crankshaft. You have used an unqualified supplier!"
Buck Green's words were reasonable and well-founded, which made everyone think deeply. Could it be that there was really a problem with the crankshaft?
One person said: "I knew that Blue Star car was unreliable. This crankshaft is not good!"
"We can't draw conclusions prematurely." Guo Ping was still very confused. He always felt that this explanation was still a little short of the truth about the engine explosion.
"You can check again." Buck Green became more confident as he spoke. "The engine explosion was entirely due to the substandard design of Blue Star Automobile's spare parts. I suggest that they be held responsible or change to a new supplier and replace the fk-30
It’s really a fool’s errand to leave the future of the engine to a car company that has only been established for two months!”
"Yes, we should ask them for details!" Other designers also agreed with his point of view.
Buck Green is a senior engine designer. He must be right when he says this. Everyone trusts this former Rover designer.
Guo Ping, Duan Rong and others checked several times, but still found nothing major. They could only attribute the explosion of the cylinder to the reasons mentioned by Buck Green.
"What? There is something wrong with the crankshaft we designed? It failed, causing your engine to explode?" Guan Yang didn't believe it at all when he heard the call from Duan Rong. He immediately retorted: "This is impossible, the crankshaft has gone from design to
I have personally inspected every step after manufacturing, and there will definitely be no problems!”
"Old Duan, you're not lying to me, are you? Your engine's cylinder explosion must be due to other reasons!"
"The research team has already concluded 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 it. If there was really a problem with their design, according to the contract, Blue Star Motors would have to compensate SAIC for certain losses.
Money is still a small thing, the most important thing is reputation!
Think about it, the first product manufactured by Blue Star Automobile had quality problems. If word spread, how would this company continue to operate in the future? No one would trust the products they manufactured.
"Our designer Buck Green has already written it clearly in the failure analysis report, which I will send to you later." Duan Rong sighed and said, "Laoguan, I don't want to see this happen.
But the engine problem is not a trivial matter. We have invested more than one billion in this project. This responsibility is too heavy and must be investigated clearly."
Guan Yang's brows twisted into the word "Chuan" again, and he said: "I want to read the fault analysis report carefully, and I will reply to you as soon as possible."
"Okay, preferably within three days. Because of this incident, the people above have lost their temper. They are considering holding your company responsible."
After hanging up the phone, Guan Yang immediately reported the incident 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. "Improper design caused excessive friction between the piston and the engine cylinder wall, causing the combustible mixture to impact the cylinder block and cause the cylinder to explode."
"Design?" Meng Xiaobai was very confused. This was designed by Jin Mu. Could it be that his design also made mistakes?
"Where's the fault analysis book? Show it to me." Meng Xiaobai asked him to read the fault analysis book. After these days of study, he could fully understand the relevant knowledge.
"I've already seen it, maybe, is this really the case?" Guan Yang's words were a bit 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 say anything and looked at the fault analysis book carefully. Soon, he slapped the fault analysis book on his desk and said dissatisfied: "It makes no sense. What kind of analysis is this?"
