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

"What the hell is wrong with this thing? Do you know that I've just lost face!"

As a result, the parts he threw away fell in front of Fang Linyan.

Fang Linyan was originally going to leave, but his heart moved, he picked up this part and looked at it carefully for a while, and then walked to the technician next to the car and said:

"Is the tolerance level of this part IT10?"

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

"No, probably around IT12. ”

The machining accuracy is measured by the tolerance grade, the smaller the grade value, the higher the accuracy, and the machining error is expressed as a numerical value, the larger the value, the greater the error. High machining accuracy means that the machining error is small, and vice versa. There are a total of 20 tolerance classes from IT01, IT0, IT1, IT2, IT3 to IT18, among which IT01 indicates the highest machining accuracy.

Fang Linyan nodded, then looked in his bag, and found an inch mirror and put it on his head, this thing was originally used by a watchmaker to repair watches, also known as an eyepiece, and others were stunned when they saw it.

Immediately afterwards, I saw Fang Linyan take out more than ten tools from his bag, including plastic surgery files, small files, pull back files, triangular files, etc., as well as vices, grinders, and a few self-made tools that others don't know.

Fang Linyan's speed can be said to be extremely skillful, almost in the blink of an eye, he assembled a fitter's temporary workbench, and then he carefully examined the part, and then began to cut.

The attention of others was on the car, and they didn't notice Fang Linyan's actions, only the technician was stunned, but only after two or three minutes, Fang Linyan ended the work in his hand, but looked at the reprocessed parts at the light, and then said:

"That's it. ”

At this time, Lao Tang had already let that Gu Shao into it, and only the technician was guarding the car, as well as the golden retriever and Director Deng next door, who were enemies, they originally came to see the joke next door, but they saw Fang Linyan's hands-on scene.

Fang Linyan came to Corvette and reinstalled the part, but the technician hurriedly stopped:

"Hey, hey, how did you put it on?"

Fang Linyan ignored him, squinted his eyes and looked at the engine, then carefully inspected it, and took out a conduit from it, and carefully polished it after removing it. The technician's face next to him changed, and he just said it, but he didn't stop it.

Because this person is very thoughtful, knowing that Gu Shao is not a reasonable person, it just so happens that there is a person like Fang Linyan who does not know whether he is alive or dead and takes the initiative to come up, if he doesn't get it well (this is almost a high probability in the heart of this technician), what will he do if he doesn't use him as a scapegoat? At least he can share most of the responsibility.

Fang Linyan's movements were very fast, dismantling, polishing, and reinstalling the series of actions were almost all in one go, and the work was completed in just five minutes, and then he began to carefully inspect again, as well as debugging, and his inspection also included tapping with a wrench, flicking his fingers, etc., it seemed that he could hear something wrong from the sound of tapping.

At this time, that Gu Shao had already walked out of it with a black face and a curse in his mouth, Boss Tang nodded and wiped his sweat, and was careful with his heart. Because the people in the store were wearing work clothes, Fang Linyan, who was moving the train, looked very conspicuous, and Gu Shao suddenly said angrily:

"Hey, what are you doing?"

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

"Wait another two minutes, and if you don't find a problem, you'll be able to drive away. ”

"What?" Gu Shao said in amazement.

Just now in it, Lao Tang has made it very clear to him that if he wants to put this car on the track again, then he must wait for the high-precision parts from Europe to come, and if he is lucky, he may arrive tomorrow, and if he is unlucky, he is afraid that he will have to wait for half a month.

If you still use second-hand dismantling parts, 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, this kid actually said to himself that he could drive away in two minutes!

"You're telling you the truth? You can drive away in two minutes? Can you get on the track?"

Fang Linyan said lightly:

"Yes, and I've just optimized the performance coefficient of the ignition advance angle, the amount of fuel injected, the time of fuel injection, and the concentration of the combustible mixture by about 5%, so that your acceleration efficiency will also be improved in the middle of the car after 80 kilometers per hour. ”

Hearing Fang Linyan's words, Gu Shao's face already showed a smile, he didn't consider whether Fang Linyan would lie to himself, because those who dared to lie to him would generally end up miserable. But after hearing Fang Linyan's words, several technicians around Old Tang all lost their temper at the same time and shouted:

"Impossible!!"

Fang Linyan had already done a good job of checking at this time, closed the hood, didn't bother to pay attention to them, and said directly:

"Alright. ”

After he said it, Gu Shao was about to step forward, but he was already squeezed away by several technicians, and with a sense of humiliation and annoyance, they directly connected to a series of instruments, and then began to hang neutral and start testing, and the results were that in the huge engine roar of Corvette, the latest parameters were released one by one.

And this Corvette has always been maintained in the shop, so the previous parameters are also very clear, the results of the comparison of the two, a dry car technician looked at each other in disbelief, only to feel that their three views are going to be subverted, because this car has not only been repaired, and the performance has really been optimized and improved! For example, the increase of 5% as Lin Yan said, is about 7%.

At this time, Director Deng was watching all this dumbfounded, and he didn't know what his mood was.

Looking at the expressions of these technicians, Gu Shao already knew it in his heart, and immediately looked at Fang Linyan and said with a smile:

"Oh! I can drive away now, can I get on the track?"

Fanglin Rock Road:

"Let's try the car first, neutral, floor oil, keep the engine speed above 12,000 for a minute, it's all right, then it's no problem at all, but remember to change the new parts on the transmission half shaft in two weeks, it should arrive at that time." ”

Gu Shao was stunned, because the engine speed of an ordinary car was almost the limit at 7,000 rpm, although his car had been changed, the limit speed was almost a little more than 10,000 rpm, and his engine speed was more than 11,000 rpm before.

Therefore, even if Gu Shao is half blind, he also knows very well that if he can really maintain an engine speed of more than 12,000 for a minute, the car will indeed be repaired.

So Gu Shao immediately said:

"Good. ”

Then he couldn't wait to get into the car and began to slam the accelerator, and the rest of the people watched Gu Shao's operation in amazement, but after a minute of test driving, Gu Shao came out of it with a smile and said:

"Yes, yes!

Fang Linyan said unhurriedly at this time:

"It's okay, you can give three hundred yuan. ”

When Gu Shao heard this, he only felt that the asking price was really too cheap and too convertible, he came here to change the car, and none of the expenses were less than five figures. took out 5,000 yuan directly from the wallet and threw it to Lin Yan, and then made a phone call, and in a hurry, he went directly to the accelerator to find someone to PK.

The rest of the people looked at each other, completely unexpectedly that things would turn to such a point. Especially Director Deng next to him, he 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 had been achieved, so he began to disassemble the fitter's console next to him in a hurry and prepare to leave.

Of course, Boss Tang would not let go of this opportunity, and came over with a smile to hand over the cigarette cliché, Fang Linyan also knew that he would have to deal with them in the future, although he didn't say anything with an enthusiastic attitude, but he also had to answer questions.

After the two exchanged a few words, Boss Tang probably felt that Fang Linyan was young and didn't have any city government, so he went straight to the point:

"Little brother, I see that you haven't changed any new parts before, how can you make Gu Shao's Corvette good?"

Fanglin Rock Road:

"Isn't the problem with his car very simple: the parts on the drive half shaft are aging and wearing, and once you enter high-performance mode, the engine is close to the limit speed. Defects in the parts led to a series of problems, culminating in a faulty light. So wouldn't it be nice to rework this old part where it is old and worn?"

Boss Tang was stunned for a while, boss, he definitely doesn't know much about in-depth business, he just thinks that the young man in front of him seems to be fine, but he always feels that something is wrong.

However, the technician beside him couldn't help it, and said a little crazy:

"That part is not a big road goods! Do you think it is Taobao 13.8 free shipping buy one get one free, that is our boss through a special channel from the Japanese Guanggang refitting factory to get, to us the price is more than 3,000 US dollars, and every time you go late, there is no more, how can it be reprocessed?"

Fanglin Rock Road:

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

The technician thought for a moment and said hesitantly:

"Well, it seems that the manual says that the filing accuracy is four thousandths of a millimeter, which is already a data that domestic car companies can't reach. ”

Fanglin Rock Road:

"My manual filing accuracy allows me to achieve machining tolerances of one thousandth of a millimeter when needed. ”
