Scholars in the courtyard

Jin Ziqiang saw the Taoist saying this and asked curiously, "Have you been to the northwest?"

The Taoist smiled and nodded, "Not only me, this old comrade Ran has also been there."

"That kid has been there too."

The three were surprised. Yang Xiaotao looked at Ran's father and didn't react. He told them roughly and let them guess the details.

Sure enough, after the three knew the identities of Ran's father and the Taoist, their faces immediately became respectful.

Ran Qiuye brought tea and fruit, and the three of them ate and talked about the past.

After talking for a while, there was a moment of silence at the table.

Jin Ziqiang looked at Wang Qiang, and Yang Xiaotao and the other two knew that it was time to get to the point, so they put down their teacups and waited.

Wang Qiang got the hint and said, "Mr. Yang, we came here this time, in addition to seeing you, we also have something to ask for."

"You said, I will definitely help if I can."

Yang Xiaotao didn't rush to agree. This was different from Fatty Ding's matter.

That one must help, this one depends on what it is.

Wang Qiang nodded, then took the briefcase from the secretary and took out two drawings from it.

After Yang Xiaotao took it, Ran's father also took a look at it, and then Yang Xiaotao asked suspiciously, "This is the engine drawing, right?"

"Yes!"

Jin Ziqiang nodded in affirmation.

"If I'm not mistaken, it should be the four-cylinder diesel engine of our machinery factory."

"Yes, that's right."

Wang Qiang nodded seriously.

Yang Xiaotao took another look, then frowned, and then put the drawings on the table, "You want to change the design?"

"How did you know?"

Wang Qiang asked subconsciously, 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. If these two places are changed, other places must also be changed."

Yang Xiaotao only took a look at the drawings to find the problem. This speed and accuracy made the two speechless.

Wang Qiang and Jin Ziqiang looked at each other, and their eyes were full of shock.

And this is not the most important thing. Yang Xiaotao tapped the table with his finger, and then said thoughtfully, "If you change these two data, the compression ratio of the gas and fuel in the cylinder will be affected."

"Generally speaking, the compression ratio of this compression ignition engine is designed to be higher. The compression ratio of this model was originally 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 engine power produced becomes smaller."

Yang Xiaotao explained while pressing the table. Ran Xinrui next to him looked at Yang Xiaotao's serious look with admiration, and then turned back to ask Ran Qiuye, "Sister, what does my brother-in-law mean by compression ratio?"

Ran Qiuye shook her head, "I'm not a science student, how would I know."

Ran Xinrui remembered that her eldest sister was a teacher training major, so she looked at Lou Xiaoe. This is her brother-in-law's secretary, and she must have been influenced by her.

Lou Xiao'e was confused, "I don't know about the compression ratio."

Ran Xinrui was speechless. She suddenly wanted to be a mechanical expert, designing machines like her brother-in-law, and explaining things to people in the same way. She would definitely feel very accomplished.

Ran's father at the table understood what Yang Xiaotao meant, but even if he understood it, he couldn't reduce his inner shock.

Being able to find the wrong things so quickly and analyze the consequences from these wrong things, this skill can only show that he is confident about this engine.

And this is just one of the many engines Yang Xiaotao has made.

The earliest single-cylinder diesel engine, the current eight-cylinder diesel engine, and now I heard that he is going to make an aircraft engine.

This.

At this time, Ran's father suddenly wanted to call Lao Zheng and tell him about Yang Xiaotao's situation.

But thinking that aircraft engines and diesel engines are completely two concepts, he gave up this idea.

Just when Ran's father was thinking, Jin Ziqiang and the others had opened their mouths wide, looking at Yang Xiaotao, shocked and not knowing what to say.

Papapapa

Jin Ziqiang didn't know what to say, so he could only purse his lips and applaud to express his admiration for Yang Xiaotao.

"High, too high, you are really amazing."

"It's better to see it in person than to hear about it. Once an expert makes a move, you can tell whether it is good or not."

Compared to him, Wang Qiang was more excited.

They are all technical people. I have been working on it for so long, but he can see my problems at a glance and point out the crux of the problem. This is the gap.

I have to admit that he is better than me.

"Mr. Yang, we came here this time just to talk about what you said."

Jin Ziqiang spoke up and finished the purpose of coming here.

Last year, Jiefang obtained the production drawings of the four-cylinder diesel engine of the machinery factory and also obtained a batch of engines from the machinery factory.

At that time, the automobile factory realized the nationalization of all vehicles in order to get rid of the clamp of engine imports.

Moreover, this engine is better than the modified one. It has strong power and low failure rate. Moreover, it is produced domestically and can be repaired and replaced at any time.

Under various factors, they want to use this engine to replace the original ship-modified engine.

Unexpectedly, difficulties arose at the very beginning.

Because this engine was originally designed purely for the purpose of obtaining credits, Yang Xiaotao tried to pursue perfection when designing it, so that he could obtain more credits.

Later, the machine tool technology of the machinery factory was upgraded, so the engine produced was of high precision.

The result is that after the engine enters the car factory, the precision is too high to be compatible with the car factory's supporting equipment.

Moreover, the cost of the factory producing the engine is too high. Even if they purchase several machine tools from the machinery factory, they will not be able to make ends meet and lose money.

In the past six months, their car factory has been trying to improve the capabilities of the surrounding industries, starting from supporting facilities, starting from production levels, and focusing on technical capabilities.

In the past six months, they have indeed made great progress, which is a world of difference compared to the previous crude technologies.

But while they are making progress, 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 are now more sophisticated than before.

This made them realize a reality, that is, their improvement is not as fast as others.

So the senior management held a meeting to reflect on whether this method is right or not.

If it is not right, then the results of the past six months are obvious to all.

If it is right, their new car design has not yet come out.

All this is because this engine is too good.

Finally, they also understood that they could not count on the engine of the machinery factory, because they were always on the road of progress.

And they only needed an engine for a certain stage.

So, as long as they adapted to a certain engine, they could make a new truck.

So, after finding the right direction, they started to tinker with the engine design again.

Then

After many setbacks, they came.

Asked Yang Xiaotao for help.

After Jin Ziqiang finished explaining the situation, Yang Xiaotao touched his chin and thought.

In the past, they were thinking about how to optimize and improve.

Now it’s good, it’s going backwards.

It’s really helpless.

Ran’s father on the side was also speechless after hearing this. They tried every means to improve, but they thought it was improving too fast.

It’s really a world of wonders.

The old Taoist was open-minded. In his eyes, as long as it was suitable, it would be fine.

Just like on the battlefield back then, no matter how many kinds of guns there were, as long as they could kill the enemy, it was a good gun.

Jin Ziqiang and Wang Qiang also knew that the two people’s requirements were a bit strange.

But they racked their brains and couldn't figure it out during this period.

The drawings have been revised a thousand times, but the things that were made just didn't work.

Now the workshop workers jokingly called them "just for show" when they saw them, and even their own designers had no hope.

"Well, you sit for a while, I'll think about it."

Yang Xiaotao went over the situation of the four-cylinder diesel engine in his mind and felt that it would not be difficult to change it.

Jin Ziqiang and Wang Qiang looked at each other, both a little unsure of what Yang Xiaotao meant.

But since the other party had said that, what else could they do?

"Director Wang, let's go inside and tell us your requirements."

Yang Xiaotao stood up, and then Wang Qiang stood up immediately.

"Boss Yang, we're not in a hurry, just help us when you have time."

Yang Xiaotao widened his eyes, then looked at Wang Qiang, "This thing is not difficult, it won't take much time."

Hearing this, Wang Qiang felt that his heart was a little bit unable to beat, and he felt uncomfortable all over.

But he still followed Yang Xiaotao into the house and came to the study.

Looking at the bookshelves around the study, Wang Qiang was shocked again.

Even their factory director wouldn't have so many books at home.

As he was looking at the bookshelf, Yang Xiaotao's voice came from beside him.

Wang Qiang looked over and saw Yang Xiaotao taking out a large file box from the kitchen under the table.

He took a look and saw the words "four-cylinder diesel engine" on the cover.

Then he 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 of the previous design. I think it will be helpful."

Yang Xiaotao said, Wang Qiang's face was embarrassed.

It felt like he had to find the second one when there was obviously the first one.

However, Yang Xiaotao acted quickly, and Wang Qiang didn't care to think too much. He sat aside and talked to Yang Xiaotao about the design requirements.

"Well, in this case, this has to be changed."

Hearing Wang Qiang's request, Yang Xiaotao took out a semi-finished design drawing and redesigned it with a pencil.

Wang Qiang watched from the side, and saw Yang Xiaotao pick it up to look at it, erase it with an eraser, and then take out a new paper to redesign it.

He could see that Yang Xiaotao was really designing.

It's just that this kind of design requires a lot of factual verification. It doesn't work to calculate it only based on the design data.

But Wang Qiang didn't dare to say much, just watched from the side.

"Ding, congratulations to the host, successfully designed the 'four-cylinder diesel engine', the evaluation level is good-medium!"

"Ding, congratulations to the host, get 1000 credits."

"Ding, it is found that the host's design of the 'four-cylinder diesel engine' has a higher evaluation level, and this reward is halved."

"Ding, congratulations to the host, get 500 credits."

After an unknown period of time, Yang Xiaotao heard the voice of the system, and his heart was relieved.

Then he looked at the modified engine drawings.

This stack is not small.

It's just this evaluation.

The original four-cylinder diesel engine was rated excellent-medium, but now it's good, it has dropped a level.

The credit reward also changed from 5,000 to 1,000, and then to 500.

However, although the credit reward was reduced tenfold, the system evaluation still showed that the design was successful.

Even if it is a little low, it is still a qualified product.

Yang Xiaotao organized the design drawings and stood up and walked out.

At this time, it was not dark yet. Looking at the time, it was only two hours.

Wang Qiang, who was flipping through a book, suddenly saw Yang Xiaotao stand up, put down the book, and asked, "Mr. Yang, don't worry about this matter. It's useless to worry."

"It's great that you can help us. We are not in a hurry."

Wang Qiang thought Yang Xiaotao was tired, so he hurried forward to comfort him.

Yang Xiaotao didn't say anything, but handed the design drawings in his hand to him, "Take it. If you lose it, I won't make a second copy."

Wang Qiang subconsciously took the drawings, and then looked at Yang Xiaotao in surprise, "You, no, you, this drawing is"

Wang Qiang stumbled and said, a little unbelievable.

"This design is made according to your requirements, take it back and try it."

"But it shouldn't be a big problem."

Yang Xiaotao walked out.

Wang Qiang held the design drawing in his hands, his expression changed from shock to disbelief, and he didn't even know how he followed Yang Xiaotao out.
