Vol 2 Chapter 119: Technology shock 4

Gu Shao took the parts handed over by Tang, and took a look at them randomly, then lost them, and said arrogantly:
"The problem with this thing is my bird thing? Do you know that I just lost face!"
As a result, the parts that he threw away fell in front of Fang Linyan.
Fang Linyan was going to leave. With a movement in his heart, he picked this part up and examined it for a while, then walked to the technician next to the car and said:
"Is this part to IT10?"
The technician looked at Fang Linyan for a moment, because the question asked by Fang Linyan was exactly on the idea, and it was not a confidential parameter.
"No, it's probably around IT12."
Machining accuracy is measured with tolerance grades. The smaller the grade value, the higher the precision; the machining error is expressed by a numerical value. The larger the value, the greater the error. High processing accuracy means small processing error and vice versa. There are a total of 20 tolerance levels from IT01, IT0, IT1, IT2, IT3 to IT18, of which IT01 has the highest machining accuracy.
Fang Linyan nodded, and found it in his bag. He found out an loupe and put it on his head. This thing was originally used by watchmakers to repair watches, and was also called eyepieces. It was also a moment.
Immediately afterwards, I saw Fang Linyan digging out more than ten tools from his own bag. The file alone has a plastic file, a small file, a pull back file, a triangular file, etc., as well as a bench vise and a grinder. There were also a few homemade tools that nobody knew.
Fang Linyan's speed can be said to be extremely skilled, almost a blink of an eye, he assembled a fitter's temporary work table, and then he carefully looked at that part, and then began cutting.
The attention of everyone else was on the car, and I didn't notice the movement of Fang Linyan. Only the technician saw it for a moment, but after only two or three minutes, Fang Linyan ended the work in his hand, but reprocessed it. Passed parts looked at the light, and then said:
"Okay."
At this time, Lao Tang had let that Gu Shao inside, and only the technician who was guarding the car, as well as Jin Mao and Director Deng next door. The colleagues were enemies. They originally came to see the joke next door, but watched To the scene of Fang Linyan's hands-on operation.
Fang Linyan came to Corvette and reinstalled the part. The technician hurriedly stopped:
"Hey, hey! How did you put it on?"
Fang Linyan ignored him, squinted his eyes and looked at the engine, and then inspected it carefully. Then he removed a duct from the top and carefully polished it after removing it. The technician next to him changed his face, but just talked, but he didn't stop.
Because this person has a very serious mind, knowing that Gu Shao is not a reasonable person, there is actually a person like Fang Linyan who doesn't know how to live or die, and if he can't get it right (this is almost a high probability in the mind of this technician), What if you don't take him as a scapegoat? At least I can share most of the responsibilities.
Fang Linyan's actions were very fast. The series of actions of disassembly, grinding, and reinstallation were almost done in one go. The work was completed in just five minutes, and then he began to carry out a careful inspection and commissioning. During his inspection, , Also includes methods such as tapping with a wrench, finger movement, etc. It seems that you can hear something wrong from the sound of tapping.
At this time, Gu Shao had come out with a shameful mouth and scolding, and Boss Tang nodded, wiping his sweat, and stayed careful. Because the people in the store were wearing work clothes, Fang Linyan, who was moving the car, looked very conspicuous, and Gu Shao said angrily:
"Hey, what are you doing?"
Fang Linyan raised his head and gave him an indifferent glance:
"Wait for another two minutes and you can drive away without checking the problem."
"What?" Gu Shao said suddenly.
Just now, Tang has made it very clear to him. If he wants to get on the track again, he must wait for the high-precision parts from Europe. Good luck. Maybe it will arrive tomorrow. If so, I'm afraid it will take half a month.
If second-hand dismantling parts are also used, there is no guarantee that problems will not occur on the track.
Gu Shao finally accepted this fact. I didn't expect that when he went out, the boy said to himself that he could drive away in two minutes! !! However, people always like to hear the good news, and Gu Shao is no exception to this kind of rich and willful man. He was somewhat surprised:
"What are you talking about? You can drive in two minutes? Can you go to the track?"
Fang Linyan Light Road:
"Yes, and I just optimized it to improve the four coefficients of performance of the ignition advance angle, the amount of fuel injected, the time of injection, and the concentration of the combustible gas mixture. In this case, your speed is at After being upgraded to 80 kilometers, the acceleration performance will be improved to some extent. "
After hearing Fang Linyan's words, Gu Shao's face was already smiling. He did not consider whether Fang Linyan would lie to himself, because those who dared to lie to him would generally be miserable. But after hearing Fang Linyan's words, several technicians around Lao Tang lost their gaze at the same time, shouting:
"impossible!!"
Fang Linyan had already done the inspection at this time, closed the hood, and didn't bother to care about them, directly:
"All right."
After he had said it well, Gu Shaozheng was about to come forward, but he was squeezed away by several technicians. With a feeling of humiliation and anger, they directly connected a series of instruments, and then started testing in neutral. As a result, among the huge engine roar of Corvette, the latest parameters were released one by one.
And this Corvette has always been maintained in the store, so the previous parameters are also very clear. As a result, the two are compared, and an automobile technician is incredulous, and only feels that his three views must be affected. Subverted, because not only has this car been repaired, but its performance has really been improved! It is even higher than Fang Linyan said that the increase is 5%, which is about 7%.
At this time, Director Deng stared at it all with a stun and didn't know how he felt.
Looking at the expressions of these technicians, Gu Shao was already aware of it, and immediately looked at Fang Linyan with a smile:
"Wow! I can drive now? Can I go to the track?"
Fanglin Rock Road:
"Try the car first, neutral, floor oil, try to keep the engine speed above 12,000 for one minute. At this time, there is no problem, then it is completely okay, but remember to change the drive shaft in two weeks. New parts, they should be in stock by then. "
Gu Shao stunned, because the speed of the ordinary car engine is almost at 7000 rpm. Although his car has been changed, the limit speed is almost more than 10,000. Before, his engine speed was over 10,000. Problems after a thousand revolutions.
Therefore, even though Gu Shao is considered half-blind, it is also clear that at this time, if the engine speed of more than 12,000 can be maintained for one minute, this car will be repaired.
So Gu Shao said immediately:
"it is good."
Then he couldn't wait to get into the car and started to blast the throttle. The rest of the people were stunned and watching Gu Shao's operation. As a result, after one minute of the test run, Gu Shaomei burst out with a smile:
"Nice, yes! Tough!"
Fang Linyan said at this time:
"It's okay, you give three hundred dollars."
Gu Shao heard it, but only felt that the asking price was really too cheap and too expensive. He came here to change the car, and the cost was not lower than five figures. I took 5,000 yuan directly from my wallet and threw it to Lin Yan, and then I made a phone call, and anxiously went straight to the throttle to find someone.
The rest of the people looked at each other, but did not expect that the peak circuit turned to such a point. In particular, Director Deng next to him was completely stunned, and his face was hotter at the same time, not even having the courage to face Jin Mao.
After Fang Linyan had made money this time, the purpose of coming here has been achieved, and he began to dismantle the fitter's operating table next to him, ready to leave.
Boss Tang certainly won't let go of this opportunity. He smiled over and handed over his cigarettes. Fang Linyan also knew that he had to deal with them in the future. Although he didn't say anything enthusiastic, he still had to answer questions.
After a few words of embarrassment between the two, boss Tang probably thought that Fang Linyan was young and there was no city government, so he went straight to the theme:
"Little brother, I don't think you have changed any new parts before. How can you make Gu Shao's Corvette just fine?"
Fanglin Rock Road:
"Isn't his car a very simple problem? The parts on the drive shaft are worn and worn. Once in high-performance mode, the engine is approaching the limit speed. Defects in the parts cause a series of problems, and eventually the fault light is turned on. Wouldn't it be nice to rework this old and worn part? "
Boss Tang was stunned for a while. Boss, he definitely didn't know much about deep business. I just felt that the guy in front of him seemed to be fine, but I always felt that there was something wrong.
But the technicians around him couldn't help it ~ EbookFREE.me ~ A little crazy:
"That part is not a big deal! You thought it was Taobao's 13.8 free shipping, which was bought by our boss from a modification factory in Gwanggang, Japan through special channels, and the price quoted to us was more than three thousand dollars. , And every time I go late, it's gone. How could it be reworked? "
Fanglin Rock Road:
"I looked at it. The filing accuracy of this part should be about four thousandths of a millimeter, right?"
The technician thought for a while and hesitated:
"Well, it seems that the file is written with a precision of 4 millimeters, which is already beyond the reach of domestic car companies."
Fanglin Rock Road:
"My hand filing accuracy can reach machining tolerances of one-thousandth of a millimeter when needed."
