Seeing the old Taoist say this, Jin Ziqiang asked curiously, "Have you ever been in the northwest?"
The old Taoist smiled and nodded, "It's not just me, Comrade Lao Ran has also been there."
"Even this kid has been there too."
The three of them were surprised. Yang Xiaotao glanced at Ran's father and showed no reaction, so he gave a general explanation and let them guess the details.
Sure enough, after the three of them learned the identities of Ran's father and Lao Dao, their faces immediately became respectful.
Ran Qiuye brought the tea and fruit, and the three of them chatted about the past while eating.
After talking for a while, the table was quiet for a while.
Jin Ziqiang glanced at Wang Qiang, Yang Xiaotao and the others knew it was time to get down to business, so they put down their teacups and waited.
Wang Qiang received the prompt and said, "Gong Yang, we have taken the liberty to come here this time. In addition to meeting you, we also have something to ask for."
"You said, I will definitely help you if I can."
Yang Xiaotao didn't rush to agree, which was different from what happened with Fatty Ding.
That one must be helped, and that one depends on what the matter is.
Wang Qiang nodded, then took the briefcase carried by the secretary and took out two drawings from it.
After Yang Xiaotao took it, Ran's father also looked at it, and then Yang Xiaotao asked doubtfully, "This is the engine blueprint, right?"
"right!"
Jin Ziqiang nodded in affirmation.
"If you read it correctly, it should be a four-cylinder diesel engine from our machinery factory."
"Yes, that's right."
Wang Qiang nodded seriously.
Yang Xiaotao looked at it again, then frowned, and then put the drawing on the table, "You want to change the design?"
"How did you know?"
Wang Qiang subconsciously asked, but Yang Xiaotao pointed to two places on the design drawing, "Here and here, the original data was eight and three point two, but now it is nine and four point four. These two places have been changed, and the other
Localities also need to make changes.”
Yang Xiaotao could find the problem just by looking at the drawings. This speed and accuracy left the two of them speechless.
Wang Qiang and Jin Ziqiang looked at each other with shock in their eyes.
And that's not the most important thing. Yang Xiaotao pointed at the table and said thoughtfully, "If you change these two data, the compression ratio of the gas and fuel in the cylinder will have an impact."
"Generally speaking, the compression ratio of this kind of compression-ignition engine is designed to be higher. The original compression ratio of this model was between 18 and 21."
"If you change the size, it is equivalent to increasing the denominator. At the same fuel supply rate, the compression ratio cannot be achieved, and the power of the produced engine will become smaller..."
Yang Xiaotao explained while holding the table. Ran Xinrui next to him looked at Yang Xiaotao's serious look with admiration on his face. Then he turned back and asked Ran Qiuye, "Sister, what does the compression ratio that brother-in-law mean?"
Ran Qiuye shook his head, "I'm not a science major, how would I know."
Ran Xinrui remembered that her eldest sister was a teacher major, so she looked at Lou Xiao'e, she was her brother-in-law's secretary, so she must have been influenced by what she heard and saw.
Lou Xiao'e looked confused, "I don't know the compression ratio."
Ran Xinrui was speechless. She suddenly wanted to be a mechanical expert. Designing machines like her brother-in-law, and being able to answer people's questions like this would definitely be a great sense of accomplishment.
Ran's father at the table did understand the meaning of Yang Xiaotao's words, but this understanding could not reduce the shock in his heart.
Being able to discover the wrong things so quickly and analyze the consequences from these wrong places, this skill can only show that he is confident about the engine.
And this is just one of the many engines Yang Xiaotao has developed.
The earliest single-cylinder diesel engine, to the current eight-cylinder diesel engine, and now I heard that we are going to build an aircraft engine.
this...
At this time, Ran's father suddenly wanted to call Lao Zheng and tell him about Yang Xiaotao's situation.
However, when I thought that aircraft engines and diesel engines were completely different concepts, I gave up this idea.
Just as Ran's father was thinking, Jin Ziqiang and the other two had opened their mouths and looked at Yang Xiaotao, so shocked that they didn't know what to say.
bang bang bang
Jin Ziqiang didn't know what to say, so he could only express his admiration for Yang Xiaotao by applauding with his lips pursed.
"High, too high, you are really amazing."
"Famous is not as good as seeing it. Once an expert takes action, he will know whether it is there or not."
In comparison, Wang Qiang was even more excited.
They are all engaged in technology. After doing it for so long, others can see their problems at a glance and tell them the crux of the problem. This is the gap.
I have to admit that others are better than me.
"Mr. Yang, we are here this time just for what you said."
Jin Ziqiang then opened his mouth and finished explaining the purpose of coming here.
Last year, Jiefang obtained the production drawings of the four-cylinder diesel engine from the machinery factory, and also obtained a batch of engines from the machinery factory.
At that time, in order to get rid of the constraints of engine imports, automobile manufacturers nationalized all vehicles.
Moreover, this engine is better than the modified one, not only has strong power, but also has a low failure rate. It is also produced in China and can be repaired and replaced at any time.
Due to various factors, they wanted to use this engine to replace the original ship modified engine.
Unexpectedly, I encountered difficulties at the very beginning.
Because when this engine was first developed, it was purely for gaining credits, so when Yang Xiaotao designed it, he tried his best to pursue perfection so as to gain more credits.
Subsequently, the machine tool technology in the machinery factory was upgraded, and the engine produced was very precise.
The result is that after the engine enters the automobile factory, the accuracy is so high that the automobile factory's supporting equipment is incompatible.
Moreover, the cost of the factory that produces engines is too high. Even if you purchase several machine tools from a machinery factory, you will still be unable to make ends meet and lose money.
In the past six months, their automobile factory has been trying to improve the capabilities of surrounding industries, starting from supporting facilities and production levels, and paying close attention to technical capabilities.
In the past six months, they have indeed made great progress. Compared with the rough technologies before, it can be said to be a world of difference.
But they are making progress, and the machinery factory is not idle either.
Especially with the improvement and popularization of the Venus machine tool series, the four-cylinder diesel engines produced by the machinery factory today are more sophisticated than before.
This made them realize the reality that they were not improving as fast as others.
So the top management held a meeting to reflect on whether this approach was right or not.
If I’m not right, the results of the past six months are obvious to all.
To be fair, their new car design hasn't been released yet.
All because this engine is so good.
Finally, they also understood that they could not count on the engine from the machine shop, because they were always on the road to progress.
And they only need a certain stage of engine.
Therefore, as long as they adapt to a certain engine, they can make a new truck.
So, after finding each other, they started tinkering with the engine design again.
Then...
After many blows, here they come...
Ask Yang Xiaotao for help.
After Jin Ziqiang finished explaining the situation, Yang Xiaotao touched his chin and thought.
In the past, I was always thinking about how to optimize and how to improve.
It's good now, it's going backwards.
It's so helpless.
Ran's father on the side was equally speechless after hearing this. They tried every possible means to improve, but they felt that the improvement was too fast.
It’s such a vast world, filled with wonders and wonders.
But the old Taoist is very open-minded, as long as it is suitable in his eyes.
Just like on the battlefield, don't look at all kinds of guns. As long as it can kill the enemy, it is a good gun.
Jin Ziqiang and Wang Qiang also knew that their requests were a bit strange.
But during this period, they racked their brains and couldn't figure it out.
I've changed this drawing a thousand and eight hundred times, but the finished product just doesn't work.
Now when the workshop workers see them, they all jokingly call them soy saucers, and even their own designers have given up hope.
"Well, you guys sit down for a while and I'll think about it."
Yang Xiaotao mentally reviewed the situation of the four-cylinder diesel engine and felt that it would not be difficult to make changes.
Jin Ziqiang and Wang Qiang looked at each other, both unsure of what Yang Xiaotao meant.
But the other party has already said this, what else can they do?
"Director Wang, let's go inside and talk about your requirements."
Yang Xiaotao stood up, and then Wang Qiang stood up immediately.
"Mr. Yang, we are not in a hurry. Just help when you have time."
Yang Xiaotao's eyes widened, and then he looked at Wang Qiang, "This thing is not difficult and it doesn't take much time."
Hearing this, Wang Qiang felt that his heart had stopped beating, and he felt uncomfortable all over.
However, he still followed Yang Xiaotao into the house and came to the study.
Looking at the bookshelves around the study room, Wang Qiang swept his eyes and was shocked again.
Even their factory director doesn’t have so many books at home.
While looking at the bookshelf, Yang Xiaotao's voice came from beside me.
Wang Qiang quickly looked over and saw Yang Xiaotao taking out a large document box from the kitchen under the table.
He took a look and saw the words four-cylinder diesel engine on the cover.
Then I saw Yang Xiaotao opening the box and taking out the drawings inside. There was also a pile of draft paper at the bottom.
"This is the first draft from the previous design, I think it will be helpful."
Yang Xiaotao said, Wang Qiang looked embarrassed.
It feels like there is clearly a number one, but I insist on finding the number two.
However, Yang Xiaotao acted very quickly, and Wang Qiang didn't have to think too much. He sat aside and talked about the design requirements with Yang Xiaotao.
"Well, in this case, we have to change this place."
After hearing Wang Qiang's request, Yang Xiaotao took out a semi-finished design drawing and redesigned it with pencil.
Wang Qiang watched from the side, and saw Yang Xiaotao picking it up to look at it, erasing it with an eraser, and taking out new paper to redesign.
He could see that Yang Xiaotao was really planning.
It's just that this kind of design requires a lot of factual verification, and it's simply not feasible to make calculations based only on design data.
However, Wang Qiang did not dare to say more and just watched from the side.
"Ding, congratulations to the host for successfully designing a 'four-cylinder diesel engine'. The evaluation grade is good-medium!"
"Ding, congratulations to the host, you got 1000 credits."
"Ding, we found that the host's design 'four-cylinder diesel engine' has a higher evaluation level, this reward will be halved."
"Ding, congratulations to the host, you got 500 credits."
I don't know how long it took, but Yang Xiaotao heard the sound of the system and felt relieved.
Then look at the revised engine drawings.
This pile is quite a lot.
This is just a review.
The original four-cylinder diesel engine had an excellent-medium rating, but now it is so good that it has dropped down a notch.
The credit reward also changed from the original five thousand to one thousand, and then to five hundred.
However, although the credit award has shrunk tenfold, the system evaluation still shows that this design was successful.
Even if it is a bit low, it is still a qualified product.
Yang Xiaotao arranged the design drawings, stood up and walked out.
At this time, it was still dark, and looking at the time, it was only two hours.
Wang Qiang, who was reading a book at the side, suddenly saw Yang Xiaotao standing up. He quickly put down the book and stepped forward and asked, "Mr. Yang, there is no need to worry about this matter. There is no point in being anxious."
"It would be great if you could help us. We are not in a hurry."
Wang Qiang thought Yang Xiaotao was tired, so he quickly stepped forward to comfort him.
Yang Xiaotao didn't say anything, but just handed the design drawing in his hand to him, "Take it, I won't make a second copy if you lose it."
Wang Qiang subconsciously took the drawing, and then looked at Yang Xiaotao with some surprise, "You, no, you, this drawing is..."
Wang Qiang stumbled as he spoke, somewhat unbelievable.
"This design was made based on your requirements. Take it back and try it out."
"However, it shouldn't be a big problem."
Saying that, Yang Xiaotao walked out.
Wang Qiang held the design drawings in his hands, his expression sometimes shocked, sometimes incredulous. He didn't know how he followed Yang Xiaotao out.
