Chapter 186

Gu Shao took the parts handed over by Old Tang, glanced at them casually, and threw them away, and said arrogantly:

"The problem with this thing is none of my business? Do you fucking know that I just lost face!"

As a result, the part he dropped casually fell in front of Fang Linyan.

Fang Linyan was about to leave, so he picked up the part and looked at it carefully for a while, then walked to the technician next to the car and said:

"Is the tolerance level of this part up to IT10?"

The technician looked at Fang Linyan in amazement, because the question Fang Linyan asked happened to be on the point, and it was not a confidential parameter, and said:

"No, probably around IT12."

The machining accuracy is measured by the tolerance grade, the smaller the grade value, the higher the precision; the machining error is expressed by a numerical value, the larger the numerical value, the greater the error.High machining accuracy means small machining error, and vice versa.There are 01 tolerance levels from IT0, IT1, IT2, IT3, IT18 to IT20, among which IT01 means the highest machining accuracy of the part.

Fang Linyan nodded, then searched in his bag, and suddenly found a loupe and put it on his head. This thing was originally used by watchmakers to repair watches, and it was also called an eyepiece. I was also taken aback.

Immediately afterwards, Fang Linyan took out more than a dozen tools from his bag. Files alone include plastic files, small files, pull-back files, three-edged files, etc., as well as bench vises, grinders, There are also a few self-made tools that others don't know.

And Fang Linyan's speed can be said to be extremely skilled. He assembled a temporary fitter's workbench almost in the blink of an eye, and then he looked at the part carefully, and then began to cut it.

Other people's attention was on the car, and they didn't notice Fang Linyan's actions. Only the technician was stunned. After two or three minutes, Fang Linyan finished the work in hand, but reworked the work. The passed parts looked at the light, and then said:

"Okay."

At this time, Old Tang had already let that Young Master Gu in, and the only ones guarding the car were the technician, as well as Jin Mao and Director Deng next door. It's time for Fang Linyan to operate.

Fang Linyan came to the Corvette (Corvette) and reinstalled this part. The technician hurriedly stopped him:
"Hey, hello! How did you put it on?"

Fang Linyan ignored him, squinted his eyes and looked at the engine, then checked it carefully, and took out a pipe from it, and polished it carefully after removing it.The technician next to him changed his expression, he just talked about it, but didn't stop him.

Because this person is very thoughtful, and he knows that Young Master Gu is not a reasonable person, and it happens that someone like Fang Linyan, who does not know how to live and die, will take the initiative to join him. , why not use him as a scapegoat?At least it can share most of the responsibility.

Fang Linyan's movements were very fast. The series of actions of dismantling, grinding, and reinstalling were almost done in one go. He completed the work in just 5 minutes, and then began to conduct careful inspections and debugging again. , It also includes methods such as tapping with a wrench, flicking your fingers, etc. It seems that you can hear something wrong from the sound of tapping.

At this time, Young Master Gu came out of the room with a sullen face cursing in his mouth. Boss Tang nodded and knelt down, wiping his sweat, and kept being careful.Because the people in the store are all wearing work clothes, Fang Linyan who is moving the car is very conspicuous, Gu Shao suddenly said angrily:

"Hey, what are you doing?"

Fang Linyan raised his head, glanced at him indifferently and said:

"Wait another 2 minutes, and if there is no problem found in the inspection, you can drive away."

"What?" Young Master Gu asked in astonishment.

Old Tang had already made it very clear to him just now that if his car wants to go on the track again, it must wait for high-precision parts from Europe to come. If you are lucky, it may arrive tomorrow. If you are not lucky If it's good, I'm afraid it will take half a month.

If second-hand disassembled parts are still used, then there is no guarantee that there will be no problems on the track.

Gu Shao finally accepted this fact, but he didn't expect that as soon as he went out, the boy told himself that he could drive away in 2 minutes! !However, people always like to hear good news, and people like Young Master Gu who are rich, powerful and self-willed are no exception. He said with some surprise:
"What you said is true? Can you drive away in 2 minutes? Can you get on the track?"

Fang Linyan said lightly:

"Yes, and I have just optimized the performance coefficient of the four items of ignition advance angle, fuel injection amount, fuel injection time, and the concentration of combustible mixture increased by about 5%. The mid-range acceleration performance will also be improved to a certain extent after it is increased to [-] kilometers."

Hearing Fang Linyan's words, Young Master Gu had a smile on his face. He didn't consider whether Fang Linyan would lie to him, because those who dared to lie to him would usually end badly.But after hearing Fang Linyan's words, several technicians around Old Tang lost their composure at the same time and shouted:
"impossible!!"

Fang Linyan had already done the inspection at this time, closed the hood, and didn't bother to talk to them, and said directly:

"All right."

After he finished speaking, Gu Shao was about to step forward, but was already squeezed away by several technicians. With a feeling of humiliation and annoyance, they directly connected a series of instruments, and then began to put the neutral gear to start the test. As a result, amidst the huge roar of the Corvette's engine, the latest parameters were released one by one.

And this Corvette has always been maintained in the shop, so they are very clear about the previous parameters. As a result, comparing the two, a group of car technicians looked at each other in disbelief, feeling that their three views would be affected. Subverted, because this car was not only repaired, but its performance was really optimized!It is even higher than the 5% increase that Fang Linyan said, probably around 7%.

At this time, Director Deng was watching all this in a daze, and he didn't know how he was feeling.

Looking at the expressions of these technicians, Young Master Gu already knew what he was doing. He looked at Fang Linyan and said with a smile:
"Nice! Can I drive away now? Can I go to the track?"

Fang Linyan said:

"Let's try the car first, neutral gear, floor oil, try to keep the engine speed above 1 for [-] minute, if there is no problem at this time, it will be completely fine, but remember to change the drive half shaft after two weeks The new parts should arrive by then."

Gu Shao was stunned, because the engine speed of an ordinary car is almost the limit at 7000 rpm. Although his car has been modified, the limit speed is only a little over 1. His engine speed was more than [-] before. The problem after a thousand revolutions.

Therefore, even though Young Master Gu is half-car blind, he still knows very clearly that if he can really maintain the engine speed of more than 1 for [-] minute without any problem, the car will indeed be repaired.

So Young Master Gu immediately said:

"it is good."

Then he couldn't wait to get into the car, and started to hit the gas pedal. The rest of the people were stunned and watched Gu Shao's operation. After the 1-minute test drive was completed, Gu Shao came out of the car with a smile on his face and said:

"Not bad, not bad! Awesome!"

Fang Linyan said calmly at this time:

"It's okay, you can give me 300 yuan."

When Gu Shao heard this, he felt that the asking price was really too cheap and a conversion. When he came here to change the car, he never spent less than five figures.He directly took 5000 yuan from his wallet and threw it to Lin Yan, and then made a phone call. Impatient, he hit the gas pedal and went to find someone to PK.

The remaining group of people looked at each other in blank dismay, completely unaware that things would take such a turn.Especially Director Deng next to him was completely stunned, and at the same time, his face was even hotter, and he didn't even have the courage to look at the golden retriever.

After Fang Linyan made money this time, the purpose of coming here has been achieved, so he began to unhurriedly dismantle the fitter's operating table next to him and prepare to leave.

Of course, Boss Tang would not let go of this opportunity, and came over with a smile to pass on the cigarette routine. Fang Linyan also knew that he would have to deal with them in the future. Although he didn't say anything enthusiastic, he still answered every question.

After the two exchanged a few words, Boss Tang probably got straight to the point because he felt that Fang Linyan was young and didn't have much of a city:

"Little brother, I don't think you have replaced any new parts before. How can you make Gu Shao's Corvette just fine?"

Fang Linyan said:

"Isn't the problem with his car very simple? The parts on the transmission half shaft are aging and worn. Once the high-performance mode is entered, the engine is close to the limit speed. The defects on the parts lead to a series of problems, and finally the fault light is on. Then put Wouldn’t it be good to rework the aging and worn parts of this old part?”

Boss Tang was stunned for a while. Boss, he definitely doesn't know much about in-depth business. He just felt that the young man in front of him seemed to be right, but he always felt that there was something wrong.

But the technician beside him couldn't bear it any longer, and said a little frantically:

"That part is not a high-end product! You thought it was Taobao 13.8 free shipping, buy one and get one free. Our boss got it from the refitting factory in Guanggang, Japan through a special channel. The quotation for us was more than 3000 US dollars. And every time I go late, it will be gone, how can it be possible to reprocess it?"

Fang Linyan said:

"I looked, and the filing accuracy of this part should be around four thousandths of a millimeter, right?"

The technician thought for a while and said hesitantly:
"Well, it seems that the manual says that the filing accuracy is four thousandths of a millimeter. This is already beyond the reach of domestic car companies."

Fang Linyan said:

"My manual filing accuracy can reach a machining tolerance of one thousandth of a millimeter when needed."
