Chapter 1799: Too Precise

When Jin Ziqiang heard the Taoist say this, he asked curiously, "Have you been to the Northwest?"

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

“This kid has been there too.”

The three people were surprised. Yang Xiaotao glanced at Ran's father without any reaction. He then gave them a general idea and let them guess the details.

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

Ran Qiuye brought over tea and fruit, and the three of them ate while chatting about the past.

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

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

Wang Qiang got the hint and said, "Engineer Yang, we came here this time not only to see you, but also to ask for something."

"You tell me, I will help if I can."

Yang Xiaotao was not in a hurry to agree, as this was different from Fatty Ding's matter.

That one must be helped, this one depends on what the matter 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. Then Yang Xiaotao asked suspiciously, "This is the engine blueprint, right?"

"Correct!"

Jin Ziqiang nodded in affirmation.

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

"Yes, that's right."

Wang Qiang nodded seriously.

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

"How did you know?"

Wang Qiang asked subconsciously, but Yang Xiaotao pointed at two places on the design drawing and said, "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 was able to find the problem just by taking a quick look at the drawings. His speed and accuracy left the two speechless.

Wang Qiang and Jin Ziqiang looked at each other, with shock in their eyes.

And this is not the most important thing. Yang Xiaotao tapped the table with his finger and 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 type of compression ignition engine is designed to be higher. The 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 engine power produced will be reduced."

Yang Xiaotao explained while tapping the table. Ran Xinrui, who was standing next to him, looked at Yang Xiaotao's serious expression with admiration, then turned around and asked Ran Qiuye, "Sister, what does the compression ratio that my brother-in-law mentioned mean?"

Ran Qiuye shook his head. "I'm not a science major, how would I know?"

Ran Xinrui remembered that her elder sister majored in education, so she looked at Lou Xiao'e. She was her brother-in-law's secretary, so she must have been influenced by him.

Lou Xiao'e was confused. "Compression ratio, I don't know."

Ran Xinrui was speechless. She suddenly wanted to be a mechanical expert, designing machines like her brother-in-law and answering people's questions in the same way. It would definitely be a great sense of accomplishment.

Mr. Ran at the table understood what Yang Xiaotao meant, but even though he understood it, it did not reduce his inner shock.

Being able to spot the error so quickly and analyze the consequences from it, this skill can only prove that he is confident about the engine.

And this is just one of the many engines developed by Yang Xiaotao.

From the earliest single-cylinder diesel engine to the current eight-cylinder diesel engine, now I heard that they are going to develop aircraft engines.

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

However, when I thought that aircraft engines and diesel engines are two completely different concepts, I gave up this idea.

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

Papapa

Jin Ziqiang didn't know what to say, so he could only clap with his lips pursed to express his admiration for Yang Xiaotao.

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

"Seeing is believing. Once an expert makes a move, you can tell whether it is good or not."

In comparison, Wang Qiang was more excited.

We are all technical people and have been doing it for so long, but others can see our problems at a glance and point out the crux of the problem. This is the gap.

I have to admit that they are better than me.

"Boss Yang, we are here this time just for what you said."

Jin Ziqiang then spoke and explained the purpose of his visit.

Last year, Jiefang obtained the production drawings of the machinery factory's four-cylinder diesel engine 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, the automobile factory nationalized all vehicles.

Moreover, this engine is better than the modified ones. Not only is it powerful, but it also has a low failure rate. Moreover, it is produced domestically and can be repaired and replaced at any time.

For various reasons, they wanted to use this engine to replace the original ship-modified engine.

But unexpectedly, I encountered difficulties at the very beginning.

Because this engine was originally developed purely for the purpose of earning credits, Yang Xiaotao tried his best to pursue perfection when designing it so that he could earn more credits.

Subsequently, the machinery factory upgraded its machine tool technology, so the engines produced were of very high precision.

The result is that when the engine enters the automobile factory, the precision is too high to be compatible with the automobile factory's accessories.

Moreover, the cost of producing engines in a factory is too high. Even if we purchase several machine tools from a machinery factory, we will still end up spending more than we earn and will still lose money.

Over the past six months, their automobile factory has been trying to improve the capabilities of surrounding industries, starting with supporting facilities and 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 techniques.

But they are making progress, and the machinery factory is not idle either.

Especially with the improvement and popularization of the Venusstar machine tool series, the four-cylinder diesel engines produced by the machinery factory today are more sophisticated than before.

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

So the top management held a meeting to reflect on whether this approach was right.

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

To be honest, their new car design has not come out yet.

All because of this great engine.

Finally, they also understood that they could not rely on the engines from the machinery factory, because they were always on the road of improvement. They only needed engines for a certain stage.

So, as long as they adapt a certain engine, they can make a new truck.

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

then
After many blows, they came.
Ask Yang Xiaotao for help.

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

In the past, I always thought about how to optimize and improve.

Now, we are going backwards.

It's really helpless.

Mr. Ran, who was standing by, was also speechless after hearing this. They were trying every possible way to improve, but they thought the improvement was too fast.

The world is so big and full of wonders.

The old Taoist, on the other hand, is open-minded. In his eyes, as long as it's suitable, it's fine.

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

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

But they couldn't figure it out no matter how hard they tried during this period.

This drawing has been revised a thousand times, but the finished product is just not good enough.

Now the workshop workers jokingly call them "just there to make up the numbers" when they see them, and even their own designers have given up hope.

"Well, you sit down 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 modify it.

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

But since the other party has said this, what else can they do?
"Director Wang, let's go inside and tell us your request."

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 his heart slow down and he felt uncomfortable all over.

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

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

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

As I was looking at the bookshelf, I heard Yang Xiaotao's voice beside me.

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

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

Then I saw Yang Xiaotao open the box and take out the drawings inside. There was a pile of draft paper at the bottom.

"This is a rough draft from a previous design. I think it will be helpful."

As Yang Xiaotao spoke, Wang Qiang looked embarrassed.

It feels like there is already a first place, but I insist on finding the second one.

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

"Well, in that case, this place needs to be modified."

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

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

He could see that Yang Xiaotao was really designing.

However, this kind of design requires a lot of factual verification, and it is simply not feasible to calculate based solely on design data.

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

"Ding, congratulations to the host for successfully designing a 'four-cylinder diesel engine'. Evaluation level: good-medium!"

"Ding, congratulations to the host, you have obtained 1000 credits."

"Ding, it is discovered that the host's design 'Four-cylinder Diesel Engine' has a higher evaluation level, so the reward will be halved this time."

"Ding, congratulations to the host, you have obtained 500 credits."

After an unknown amount of time, Yang Xiaotao heard the system's voice and felt relieved.

Then look at the revised engine drawings.

This pile is quite a lot.

It’s just this evaluation.

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

The credit reward also increased 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 bit low, it is still a qualified product.

After Yang Xiaotao put the design drawing in order, he stood up and walked out.

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

Wang Qiang, who was flipping through a book, suddenly saw Yang Xiaotao standing up. He quickly put down the book and walked over to ask, "Boss Yang, don't worry about this. There's no point in worrying."

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

Wang Qiang thought Yang Xiaotao was tired, so he stepped forward and tried to comfort him.

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

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

Wang Qiang spoke haltingly, somewhat unbelievingly.

"This design is based on your requirements. Take it back and try it out."

"However, it shouldn't be a big problem."

As he said this, 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.
