But when it comes to taking money, it's really uncomfortable!

Although she has money, she earned it with her youth, and when she was old, she couldn't eat this mouthful, and she still pointed to the money to support the elderly.

The money is your own, not the Jia family.

Especially there is a wicked mother-in-law!

Let her take the money to buy coal, how is it possible!

"Not true. Huairu. ”

Jia Zhang's triangular eyes turned, and he suddenly stared as if he had discovered something, "You say, Yan Fugui is helping the Zhou family so much, will he have a leg with the widow of Zhou!" ”

"Although this widow looks average, she is also stronger than the three mothers!"

"Besides, this widow has been around for so many years, who knows if she will be unable to bear the loneliness, for a bite to eat, she will have a leg!"

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

Qin Huairu's body trembled, and her heart chuckled, feeling as if she had been seen through!

glanced at Jia Zhang's slightly, and found that the other party's eyes were looking outside, and he didn't notice it at all, so he was relieved.

Then there was a sneer in my heart.

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

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

Belch!

No one should be good at this!

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

"Mom, I'll ask Aunt Yi to borrow some, it's getting colder and colder, and I don't have any coal, how can I live?"

Jia Zhang glanced at Qin Huairu, "Then you go quickly, pay the money, let Yan Fugui and them send it back, and save us a trip!" ”

Qin Huairu nodded and left, but as soon as she went out, she saw the stick terrier coming back covered in dust.

"Terrier, what's wrong with you?"

The stick terrier rubbed his blue face, pouted and said, "The school organizes a visit to the machinery factory, and I will eat at noon." ”

"I went to sign up, but the teacher wouldn't let me go, saying that only those who performed well could go."

"My classmates laughed at me, and I fought with them!"

The stick terrier said that he was wronged, in fact, he wanted to eat as much as he wanted, and said that he would see if he could bring something out and sell it to buy a candy man.

In the past, when his father was here, he sold scrap iron and bought him candy.

I haven't eaten it in a long time.

Who knows, if you can't choose it, you will simply make a fuss.

"What? Why don't you let us go? This teacher is also clumsy, what a good child we are, so well-behaved and can't be chosen? ”

"I'll go find Yan Fugui. This Red Star Elementary School is becoming less and less of a thing! ”

As he spoke, he went outside, Qin Huairu didn't care about her, let her make trouble.

If you don't make trouble, how can you not look easy?

It's just that when I saw the stick terrier like this, I was angry again.

My son finally went to school and looked for a chance to improve. But I didn't expect that the teachers in this school were not sympathetic?

If they don't study well, these teachers must be irresponsible.

"Go back to the house and see my sister! Wait for Mom to come back and cook and eat. ”

Qin Huairu slapped the stick terrier twice, and then walked to an aunt's house.

Before entering the door, I heard the quarrel between Jia Zhang's family and the three mothers in the front yard.

Alas!

I don't know how much money an aunt still has.

If you really can't do it, let's borrow less.

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

With that book,It should be an explanation!

The next day, after Yang Xiaotao came to the factory, he saw the propaganda director leading a group of people to dress up in the factory.

There are logistics, offices, and security offices, all of which are busy.

Thinking of Lao Dao's awakening yesterday, Yang Xiaotao found Zhao Chuanjun and told him about his worries.

Especially when visiting the workshop, you should be optimistic.

The area in question can only be viewed from the outside, and no one is allowed to enter the danger zone.

Zhao Chuanjun also knew Yang Xiaotao's concerns, whether it was the factory or the children, it was not a trivial matter if any party had a problem.

After saying that, Yang Xiaotao stopped caring about it, returned to the office building, and came to the R&D department.

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

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

"We calculated that to fit the size of the existing tractor, we needed to divide one cylinder in half and then consider the other components, so that each cylinder was only a third the size of the original, or even smaller."

"But in reality, to add a cylinder, you need to add a set of pistons, two valves, and an oil ring."

"On top of that, there's a camshaft, there's valve springs and so on."

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

Zhang Guanyu said the results of the discussion among several people, and Yang Xiaotao just nodded on the side.

In the previous life, there has always been a saying that the number of cylinders is justice.

So I often see what eight-cylinder, ten-cylinder, twelve-cylinder.

Regardless of whether this statement is correct or not, but the number of cylinders is more, the volume of the engine must be large.

There is no doubt about it.

Therefore, Yang Xiaotao was already prepared when he studied the drawings, which is also what he said in his discussion with Yang Youning, the new engine may not be suitable for the current tractor, and it is necessary to be ready to open a new line.

"Also, Mr. Yang."

"If you want to get higher speed according to the new engine design, in addition to power, you also need to have a matching gearbox, and the gearbox we are producing at the moment is obviously not suitable."

Zhang Guanyu spoke again and expressed the doubts in his heart.

Yang Xiaotao glanced at the drawings, many of the dimensions on them were clearly marked, and there were remarks next to them.

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

"That's really the problem. What do you guys think? ”

Zhang Guangyu glanced at each other and said the plan discussed, "Mr. Yang, in fact, we can improve the gearbox, just improve it on the Red Star tractor, and we can also increase the lifting speed." ”

Yang Xiaotao shook his head when he heard this, "It's useless, you see, there is an upper limit to the speed of a single-cylinder diesel engine, which is the main reason for limiting the speed." ”

"And you should not forget that we designed the positioning of the tractor, that is, it has a large carrying capacity, strong adaptability, and can have strong off-road ability."

"If you sacrifice carrying capacity for the sake of speed, you lose more than you gain."

Zhang Guanyu said suspiciously, "Then we design a new engine, according to the current situation, it is difficult for both parties to take care of it." ”

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

"With a new engine, it is natural to have a new tractor!"

With Yang Xiaotao's affirmation, Zhang Guanyu and others no longer stuck to the original framework and began to design the twin-cylinder engine according to their own ideas.

Yang Xiaotao didn't bother these people.

Now he can design a twin-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 eight-cylinder diesel engines.

If in the end, all the drawings are used, then when they develop better engines, it will be similar to what they are in now.

Therefore, Yang Xiaotao has been doing the training of personnel.

Of course, he will not give up the credits he has obtained, and it is a big deal to make it, and it will be announced a few days later.

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 alone in the house.

"If the engine gets bigger, the front of the car has to be bigger, so it's hard to get a 50 tractor?"

Thinking of the Dongfanghong tractor that pulled bricks and dirt in the village in his previous life, he was rumbling and running, and the driver twisted the steering wheel hard.

And every time he stopped, the driver jumped out of the car in a chic manner.

I envied these for a long time when I was a child.

Although the impression in my mind is not clear, it also points the way.

Moreover, the speed of this tractor has been increased a lot, which should be able to meet the requirements.

"Then do it, big tractors."

Yang Xiaotao made a decision in his heart and was ready to get the twin-cylinder diesel engine out first.

Take out the pen and paper from the space and start working on the design.

Not long after I sat down, the phone rang.

"Hello, who?"

"Director Xiao Yang? I'm Liu Dehui! ”

"Director Liu! You're so busy, how do you have time to think of me? ”

Yang Xiaotao smiled, and the person on the other end of the phone was Liu Dehui, the director of the city's automobile factory.

Nowadays, with the support of the military, the Quancheng Automobile Factory is becoming more and more prosperous, the scale is getting bigger and bigger, and the output is also increasing day by day.

I heard that last time, if it weren't for the sudden rise of the machinery factory, the status of the Quancheng Automobile Factory would have been higher.

Of course, this ranking is just a reputation, and there is no real benefit.

Of course, Yang Xiaotao also heard some gossip from Liu Huaimin, and it seemed that the Quancheng Automobile Factory would be divided into the logistics department, and in the future, it would specialize in the production of military products.

But it was rejected by the boss of the first machine department

He doesn't know if it's true or not, anyway, it's the leaders above who have the final say.

"Busy is busy, friendship still has to be maintained."

Liu Dehui smiled, Yang Xiaotao leaned back in the chair and smiled, "That's right, thank you for your help in the matter of the tanker truck last time." ”

"That's a little thing, and besides, there's the approval above."

"Then there is a first-come, first-served one."

The two chatted for a while, and then Liu Dehui began to talk about business, "Director Xiao Yang, I have something to ask you." ”

"I knew that there was nothing to do without going to the Three Treasures Hall. You definitely didn't call me for a drink! ”

"You, you're young, how can you be like Lao Wang, just thinking about drinking, this is not good!"

"Haha, Brother Wang has been drinking with you again recently?"

"Do you still need to think about it? I have to drink every time I come, and the last time I heard that you had come up with a new steelmaking technology, I went to my house to drink it. ”

Yang Xiaotao laughed, "Brother Wang will make excuses." ”

"Not really, but how far has your steel plant been built? Several steel factories here in Quancheng asked me to ask so that I could learn! ”

"What's the matter, who's coming, we're warmly welcome."

Yang Xiaotao agreed without thinking about it.

As long as there are more people who learn and use more, the air compressors they make will be marketable.

Moreover, there is more steel, which also promotes national construction.

Not to mention anything else, at least the infrastructure has come up, and the railway is built, and it is much more convenient to travel.

"Okay, I'll tell them when I get back."

Liu Dehui should take it down.

Yang Xiaotao thought that this was the matter, but he didn't want Liu Dehui to change his words and talk about the engine again.

"Xiao Yang, I heard that you submitted a research plan for a twin-cylinder diesel engine?"

"Yes, it was just approved!"

Yang Xiaotao suddenly thought of something in his heart, this is the real purpose of Liu Dehui's call.

Sure enough, I heard Liu Dehui's urgent voice, "Director Xiao Yang, you can all make two-cylinder ones, and the four-cylinder diesel engine is no problem!" ”

"This, I really haven't thought about it, but if you eat the two-cylinder one thoroughly, the four-cylinder one will not be far away."

Yang Xiaotao said cautiously, in his opinion, the increase in the number of cylinders is not a simple superposition, in which the design and structure are many different.

But as long as the double cylinder is eaten thoroughly, the follow-up work will be traceable.

"Really?"

"Well, it takes time to study though, what? Do you want to study diesel engines in your car factory? ”

"To tell you the truth, when you come up with a single-cylinder engine, we start researching it."

"But after such a long time, there has been no improvement, I heard that you are going to make a twin-cylinder diesel engine, so I called to ask."

Liu Dehui didn't plan to hide it, and generously admitted it.
