But I understand, when it comes to getting money, it’s really uncomfortable!

Although she has money, she earned it with her youth. When she gets older and can no longer afford to eat, she still relies on the money to support herself in old age.

That money belongs to you, not the Jia family.

Especially with an evil mother-in-law!

How is it possible for her to use money to buy coal?

"No. Huairu."

Jia Zhang's triangular eyes rolled and suddenly widened as if she had discovered something, "Tell me, if Yan Fugui is so helpful to the Zhou family, is he having an affair with the widow of Zhou?"

"Although this widow is average-looking, she is still better than the third aunt!"

"Besides, this widow has been here for so many years. Who knows if she will be unable to bear the loneliness. She might have an affair just for a bite to eat!"

Jia Zhang almost jumped up, as if she had discovered some truth.

Qin Huairu's body trembled, her heart skipped a beat, and she felt like her whole body was being seen through!

After looking at Jia Zhang for a moment, I found that the other person was looking outside and didn't notice at all, so I felt relieved.

Then he sneered in his heart again.

Speaking of widows, who in this courtyard has been there longer than Jia Zhang?

According to what Jia Zhang said, she also has a leg!

Well!

No one should like this!

Qin Huairu put down the lid of the pot and ignored the cursing Jia Zhang.

"Mom, I'm going to ask my eldest mother to borrow some. It's getting colder and colder. I don't have any coal. How will I survive?"

Jia Zhang glanced at Qin Huairu, "Then go quickly, pay the money, and let Yan Fugui and the others send it back. This will save us a trip!"

Qin Huairu nodded and left, but as soon as he went out, he saw Banggeng come back covered in dust.

"Bangge, what's wrong with you?"

Banggeng rubbed his blue face, curled his lips and said, "The school organizes a visit to the machinery factory, and we take care of lunch at noon."

"I went to sign up, but the teacher refused to let me go, saying that only those with good performance could go."

"My classmates laughed at me, so I would fight with them!"

Banggeng said he was aggrieved, but in fact he just wanted to eat more delicious food. He said he wanted to see if he could bring something out and sell it to buy a candy man.

In the past, when his father was here, he would buy candy figures for him after selling scrap metal.

Haven't eaten for a long time.

Who knows, I couldn't choose, so I just started making trouble.

"What? Why don't you let us go? This teacher is also blind. We are such a good kid, but we are so good that we can't be chosen?"

"I'm going to find Yan Fugui. This Red Star Elementary School is becoming more and more useless!"

After saying that, she walked out. Qin Huairu didn't care about her and let her make trouble.

If you don't make trouble, how can you show that you are not easy?

Just seeing Banggeng like this makes me feel angry again.

My son finally went to school and looked for an opportunity to make progress. But he didn't expect that the teachers in this school had no sympathy?

If their kids don’t study well, it must be because these teachers are irresponsible.

"Go back to the house and see your sister! Let's cook some food when mom comes back."

Qin Huairu patted the stick twice and then walked to her aunt's house.

Before I even entered the door, I heard the quarrel between Jia Zhang and the third aunt in the front yard.

well!

I don’t know how much money Auntie has left.

If it doesn't work, just borrow less.

Thinking that tomorrow is the day to meet Liu Guangqi, Qin Huairu finally felt better.

With that book, it should be an explanation!

The next day, when Yang Xiaotao arrived at the factory, he saw the propaganda director leading a group of people to dress up in the factory area.

There are people in the logistics department, people in the office, and people in the security department, all of whom are busy working.

Thinking of the old Taoist reminder yesterday, Yang Xiaotao came to Zhao Chuanjun and expressed his worries.

Especially when visiting the workshop, be careful.

Relevant areas can only be watched from a distance outside, and no one is allowed to enter the dangerous area.

Zhao Chuanjun also knew Yang Xiaotao's concerns. Whether it was the factory or the children, any problem on either side was not a trivial matter.

After the matter was settled, Yang Xiaotao stopped caring, returned to the office building, and came to the R&D Department.

In the room, Zhang Guanyu was leading several people to sort out the drawings.

After Yang Xiaotao walked in, Zhang Guanyu stepped forward and said, "Mr. Yang, these are some drawings of the Red Star tractor. This is the drawing of the single-cylinder diesel engine."

"After our calculations, if we want to meet the size of the existing tractor, we need to divide a cylinder into two halves, and then consider other components, so that the size of each cylinder is only one-third of the original, or even smaller."

"But in fact, adding a cylinder requires adding a set of pistons, two valves, and an oil ring."

"In addition, there must be a camshaft, valve springs, etc."

"If you want to manufacture it according to this size, not only will the technical difficulty be greatly increased, it will be very troublesome to manufacture in the future, but the power produced may not be greater than that of a single cylinder!"

Zhang Guanyu told the results of the discussion between several people, and Yang Xiaotao just nodded aside.

There has always been a saying in previous lives that the number of tanks is just.

So we often see eight-cylinder, ten-cylinder, or twelve-cylinder ones.

Regardless of whether this statement is correct or not, if there are more cylinders, the engine must have a larger volume.

There is no doubt about this.

Therefore, Yang Xiaotao was already prepared when he was studying the drawings. This was also what he mentioned when discussing with Yang Youning. The new engine may not be suitable for the current tractors, and he must be prepared to open a new line.

"Also, Mr. Yang."

"If we follow the new engine design and want to achieve higher speeds, in addition to power, we also need a matching gearbox, and the gearbox we currently produce is obviously not suitable."

Zhang Guanyu spoke again and expressed his doubts.

Yang Xiaotao glanced at the drawing. Many dimensions were clearly marked on it, and there were notes next to it.

Several people gathered around to listen to Yang Xiaotao's opinions.

"This is indeed a problem. What do you think?"

Zhang Guangyu and others looked at each other and spoke out the discussed plan, "Mr. Yang, in fact, we can improve the gearbox, just on the Red Star tractor, and we can also increase the lifting speed."

Yang Xiaotao shook his head after hearing this, "It's useless. You see, the speed of a single-cylinder diesel engine has an upper limit. This is the main reason for the speed limit."

"And don't forget that our positioning in designing tractors is to have a large carrying capacity, strong adaptability, and strong off-road capabilities."

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "If you sacrifice the carrying capacity in the pursuit of speed, you will lose more than you gain."

Zhang Guanyu said suspiciously, "Then let's design a new engine. As it is now, it's difficult to take care of both parties."

Yang Xiaotao smiled, "So, the twin-cylinder diesel engine we designed should not be limited to the framework of the Red Star tractor."

"With a new engine, of course there will be a new tractor!"

With Yang Xiaotao's approval, Zhang Guanyu and others no longer adhered to the original framework and began to design a two-cylinder engine according to their own ideas.

Yang Xiaotao did not disturb these people.

Now he can design a two-cylinder diesel engine on his own, but that doesn't mean he can do it all.

What he wants more is that these people can get exercise and have their own ideas.

After all, Yang Xiaotao's current engine drawings are only for an eight-cylinder diesel engine.

If all these drawings are used in the end, then when they develop a better engine later, they will be in a similar situation to their current situation.

Therefore, Yang Xiaotao has been doing personnel training.

Of course, he will not give up the credits he is supposed to get. At worst, it will be announced in a few days after it is completed.

After leaving the R&D Department, Yang Xiaotao returned to the office.

Lou Xiao'e was called to help maintain order, and Yang Xiaotao was the only one in the room.

"As the engine gets bigger, the front of the truck must be bigger. Is it possible to build a 50-meter tractor?"

I thought of the Dongfanghong tractor that was pulling bricks and earth in the village in my previous life. It was running with a rumble and the driver was twisting the steering wheel hard.
