Young Master Gu took the parts handed over by Old Tang, glanced at them casually, threw them away, and said arrogantly:
"What's wrong with this thing is none of my business? Do you fucking know that I was embarrassed just now!"
As a result, the parts he threw away fell in front of Fang Linyan.
Fang Linyan was about to leave, but with a thought in his heart, 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 shock, because the question Fang Linyan asked was exactly on the idea, 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 accuracy; the machining error is expressed by a numerical value. The larger the number, the greater the error. High machining accuracy means small machining error, and vice versa. Tolerance grades range from IT01,
There are a total of 20 IT0, IT1, IT2, IT3 to IT18, among which IT01 indicates that the part has the highest machining accuracy.
Fang Linyan nodded, then searched in his bag, and surprisingly found a loupe and put it on his head. This thing was originally used by watchmakers to repair watches. It was also called an eyepiece.
I was also stunned.
Immediately afterwards, I saw Fang Linyan take out more than ten tools from his bag. The files alone include plastic files, small files, rebound files, three-edge files, etc., as well as vise, grinder, etc.
There are also a few homemade tools that no one else recognizes.
Fang Linyan's speed can be said to be extremely skillful. He assembled a temporary fitter's workbench almost in the blink of an eye. Then he looked at the part carefully and started cutting it.
Everyone else's attention was on the car, and they didn't notice Fang Linyan's actions. Only the technician looked at it for a while. In the end, after only two or three minutes, Fang Linyan finished the work in his hands, but reprocessed it.
The passed parts looked at the light, and then said:
"That's it."
At this time, Old Tang had already let Mr. Gu inside. The only ones guarding the car were the technician, Jin Mao and Director Deng next door. They were enemies. They originally came to see the joke next door, but instead they saw
It’s time for Fang Linyan to take action.
Fang Linyan came to the Corvette and reinstalled the part. The technician hurriedly stopped him:
"Hey, hey! Why did you put it on?"
Fang Linyan ignored him, looked at the engine with squinted eyes, then checked it carefully, and removed a pipe from it. After removing it, he polished it carefully. The technician next to him changed his face and just said,
But didn't stop it.
Because this person is very thoughtful and knows that Mr. Gu is not a reasonable person, and someone like Fang Linyan, who does not know life and death, happens to take the initiative to get involved. If he can't do it right then (this is almost a high probability event in the technician's mind)
, why not use him as a scapegoat? At least he can share most of the responsibility.
Fang Linyan moved very quickly, disassembling, polishing, and reinstalling the series of actions almost in one go. He completed the work in just five minutes, and then began to conduct careful inspection and debugging again. During his inspection
, also includes methods such as tapping with a wrench, flicking with fingers, etc. It seems that something is wrong can be heard from the tapping sound.
At this time, Mr. Gu walked out with a dark face and cursed. Boss Tang nodded and bowed, wiping his sweat, and kept looking after him. Because everyone in the store was wearing work clothes, Fang Linyan, who was driving the train, watched
It was so conspicuous that Young Master Gu immediately said angrily:
"Hey, what are you doing?"
Fang Linyan raised his head, glanced at him indifferently and said:
"Wait another two minutes. If no problems are found, we can drive away."
"What?" Mr. Gu said in astonishment.
Old Tang had made it very clear to him just now. If his car wanted to go on the track again, he would have to wait for high-precision parts from Europe. If he was lucky, they might arrive tomorrow. If he was not,
If it's good, I'm afraid it will take half a month.
If you still use second-hand disassembled parts, there is no guarantee that there will be no problems on the track.
Mr. Gu finally accepted this fact. Unexpectedly, as soon as he went out, this guy told himself that he would be able to drive away in two minutes! However, people always like to hear good news, and rich people like Mr. Gu
People with power and willfulness are no exception. He said with some surprise:
"Are you telling the truth? You can drive away in two minutes? Can you get on the track?"
Fang Linyan said lightly:
"Yes, and I have just optimized it to increase the performance coefficients of the ignition advance angle, the amount of fuel injection, the time of fuel injection, and the concentration of the combustible mixture by about 5%. In this case, your vehicle speed will be within
The mid-range acceleration performance after 80 kilometers will also be improved to a certain extent."
After hearing Fang Linyan's words, Mr. Gu already had a smile on his face. He did not consider whether Fang Linyan would lie to him, because people who dared to lie to him would usually end up in a miserable state. But after hearing Fang Linyan's words, several people around Old Tang
The technicians all 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 pay attention to them, and said directly:
"alright."
After he said it, Mr. Gu was about to step forward, but he was already squeezed away by several technicians. With a sense of humiliation and irritation, they directly connected a series of instruments, and then started to put into neutral gear and start testing.
As a result, amid the roar of the Corvette's huge engine, the latest parameters were released one by one.
This Corvette has always been maintained in the shop, so they knew the previous parameters very well. When they compared the two, the car technicians looked at each other in disbelief, feeling that their own perceptions were being shaken.
Subverted, because not only has the car been repaired, but its performance has also been optimized and improved! It is even higher than the 5% improvement Fang Linyan said, which is probably about 7%.
At this time, Director Deng was watching all this with his mouth open, and he didn't know how he was feeling.
Looking at the expressions of these technicians, Mr. Gu already knew what was going on. He immediately looked at Fang Linyan and said with a smile:
"Awesome! Can I drive away now? Can I go on the track?"
Fang Linyan said:
"Try the car first, neutral gear, floor oil, and keep the engine speed above 12,000 for one minute. If there is no problem at this time, then it will be no problem at all. But remember to replace the transmission half shaft after two weeks.
New parts should arrive by then."
Mr. Gu was stunned, because the engine speed of an ordinary car is almost the limit at 7,000 rpm. Although his car has been modified, the limit speed is only a little over 10,000. Before, his engine speed was over 11,000.
The problem occurred after thousands of revolutions.
Therefore, even though Mr. Gu is half-car blind, he still knows clearly that if he can maintain the engine speed above 12,000 for one minute without any problem, the car will indeed be repaired.
So Mr. Gu immediately said:
"good."
Then he couldn't wait to get into the car and started to slam on the accelerator. The rest of the people stood by and stared at Gu Shao's operation. After a minute of test driving, 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, just give me three hundred yuan."
When Mr. Gu heard this, he felt that the asking price was really too cheap. He came here to modify the car and never spent less than five figures. He took 5,000 yuan from his wallet and threw it to Lin.
Yan, and then made a phone call. He was so anxious that he immediately hit the accelerator and went to find someone to PK.
The rest of the group looked at each other in shock, completely unaware that things would turn to such a turn. Especially Director Deng next to him, who was completely stunned. At the same time, his face was even more burning, and he no longer had the courage to look at the golden retriever.
After Fang Linyan made money this time, the purpose of coming here had been achieved, and he began to unhurriedly dismantle the fitter's workbench next to him and prepare to leave.
Of course, Boss Tang would not miss this opportunity. He came over with a smile and offered cigarettes. Fang Linyan also knew that he would have to deal with them in the future. Although he did not say that he was enthusiastic, he still answered all questions.
After the two exchanged a few pleasantries, Boss Tang went straight to the point, probably because he felt that Fang Linyan was young and didn't have much experience in the city:
"Little brother, I see you haven't replaced any new parts before. How can you make Mr. Gu's Corvette just as good as it is?"
Fang Linyan said:
"Isn't the problem with his car very simple? The parts on the transmission half shaft are aging and worn. Once it enters high-performance mode, the engine is close to the limit speed. The defects in the parts lead to a series of problems, and eventually the fault light comes on. So what?
Wouldn’t it be nice to reprocess the old parts where they are worn out?”
Boss Tang was stunned for a while. As a boss, he definitely didn't know much about in-depth business. He just felt that what the young man in front of him said seemed to be correct, but he always felt that something was wrong.
However, the technician beside him couldn't bear it any longer and said a little frantically:
"Those parts are not commercially available! You thought they were buy one get one free on Taobao 13.8. Our boss got them from the modification factory in Kogan, Japan through special channels. The price quoted to us was more than three thousand US dollars a piece.
, and it’s gone every time I go there late, how can I just reprocess it and it’ll be fine?”
Fang Linyan said:
"I took a look and found that the filing accuracy of this part should be about four thousandths of a millimeter, right?"
The technician thought for a while and said hesitantly:
"Well, it seems that the manual states that the filing accuracy is four thousandths of a millimeter. This is a data that domestic car companies simply cannot match."
Fang Linyan said:
"My hand-filing accuracy can reach machining tolerances of one thousandth of a millimeter when needed."
