I brought a Jurassic

Chapter 347 Research and Development Trivia
Wang Luo plans to bring them to participate in the design work of this engine. These will become his connections in the future. Even if there is a lack of technical talents after the reform and opening up, they can be pulled in to help. In addition, it will also allow them to receive better practical education so that after leaving school, they will not only have theory but no practice.

The single-cylinder engine project was officially launched, and all the skilled craftsmen in the school-run factory were gathered in this project team. The first thing they did was the conceptual design of the engine. It was Wang Luo, the person in charge who could not be considered the chief engineer, who proposed the specific data indicators of the single-cylinder engine, which would determine the main characteristics and dimensions of the engine.

"I have sent the specifications of this engine to everyone. The requirements are written on it. First, it must be fuel-efficient, with a fuel consumption of 1.5 to 2 liters, which is aimed at the situation of diesel shortage in rural areas. Second, it must be light, less than 200 kilograms. Third, it must be simple, as simple as possible, considering the maintenance problem. It cannot be too complicated, because many ordinary people use it, and they cannot repair things that are too complicated. Finally, we must consider the universal replacement of parts in the future when it is produced by various companies. We strive to make some replacement parts in some small processing plants below. This is very important. I hope everyone will pay attention to this issue.

Next, we will divide the tractor into four groups according to the main engine. One is the engine design group, which is the most important. The second is the gearbox group. The third is the rear axle group. The last is the coordination group. Don't think that this coordination group is unimportant. You need to communicate with the school leaders and summarize the current agricultural machinery manufacturers and parts processing manufacturers on the market. If there are ready-made parts on the market, we will not do additional processing. This will save time. We will strive to achieve that as long as the prototype is developed, it can be directly put into production according to the actual situation. Okay, that's all for now. Everyone should start to form groups according to their expertise and report back later."

The next day, when the names of the four groups were handed in, everyone swarmed into the first three groups, but there were few people in the coordination group. Everyone was involved in mechanics and would eventually go to various companies to work with mechanics. It was not okay to let a person who was committed to becoming a mechanical expert do the scheduling work. No one was willing to submit to anyone else, so they all gathered in the first three groups. Otherwise, it would be embarrassing to tell others about it. Did I not learn my major well?
"My fellow seniors, this won't work. There are too few people in the coordination group. We don't need that many people in the first three groups. Really, the coordination group is very important. It is the most critical department besides the engine. You are responsible for coordinating the logistics of the entire agricultural machinery. Without you, if we want to find a spare part or a nozzle, we don't know which manufacturer to contact. Let's carry forward the spirit and send a few people to the coordination group."

. . . . . .

Wang Luo kept chattering in the front, even though he was talking until his mouth was dry and saliva was flying everywhere, but no one came over, making the scene a bit awkward.

This made him a little annoyed. This wouldn't do. How could he disobey the instructions at the very beginning? He had to show his courage and call out the names.

"Since no one wants to go to the coordination group, then I will call on you, the female compatriots, to go to the coordination group and assist the entire project team with its logistics work."

"No, we won't go. Women hold up half the sky. What matters now is gender equality. We women can do the same jobs that you men can do. You are discriminating, Junior Brother. No matter how much you say, we will not agree."

The senior sister who was the leader of the female compatriots immediately refuted Wang Luo.

What my senior sister said is really true. Today's women hold up half the sky. They really do hold up the sky. They get equal pay for equal work. Women can do the same things that men can do. So it is not surprising to see many female comrades in factories doing the same jobs as men, such as electricians, machine tool workers, truck drivers, etc., and they even do a better job than the men.

This is not the same as the boxing in later generations. Theirs is not the same form as now. One is truly put into practice, and the other is just a slogan shouted to make men obey them better. If you really want them to do some dirty and tiring work that men do, they will only whimper and will never do it. At this time, they will not call men stinky, but change their words to say that we are little fairies, how can you bear to let us do this kind of thing, you are disrespecting women, haha, it's simply unreasonable.

Of course, this is only limited to boxers. The majority of our female compatriots are still very powerful. Many of them are engaged in jobs that their male compatriots do, such as those who drive trucks and do machine processing on certain audio platforms. These are the women who truly put the idea of ​​"women hold up half the sky" into practice.

"Sister, please don't put a label on me. I don't respect women. I know you are also outstanding in mechanics, and you are no worse than us men. But this coordination work really needs you women to step up. Why? Because you women are naturally more friendly than us men.

If you go to the factory to do coordination work, and a girl goes to do the handover, they will definitely be willing to deal with you. A real man would not want a girl to wait on the side. But it's different for us men. Who would want to discuss coordination issues with a rough old man? I made this decision to maximize the advantages of you female compatriots. What do you think? This reason is enough to respect you, otherwise you female compatriots are scared and dare not take on this glorious and arduous task. "

You hit me with a stick and give me a date. Girls nowadays are very naive. They cannot be compared with Wang Luo, who came from later generations and has seen all kinds of situations. A provocation and a compliment will definitely make them convinced.

"Not bad, Junior Brother, you are also good at provoking others. But it also fully shows that you respect us female compatriots and you also point out our strengths. Come on, let's take over this task. Sisters, can we do a good job in this coordination task?"

The senior sister raised her right fist and shouted slogans to cheer up the female soldiers.

"Make sure to complete the mission."

"Okay then. The logistical support of the project team is now in your hands."

This matter has come to an end, and the female compatriots are also very happy. The importance of the task can reflect their value.

"Junior brother, I admire you so much. I didn't expect you to have this skill."

"That's amazing! All the female soldiers obey you. I have to admit I'm better than you."

A group of big men gave Wang Luo a thumbs up to express their recognition of his achievements.

"Alright, alright, hurry up. Now that the groups have been divided, let's hurry up and do the research. Let's start with a simple one, the gearbox. Let's see what suitable products are on the market. The coordination group should hurry up and compile the gearboxes. If they can't be used, we will re-develop them. If our factory can make gears and the like, we will make them ourselves. If we can't make them, we will find relevant units to coordinate with. It's that simple. Come up with the best solution. The same goes for the rear axle group, especially in terms of calculations. I believe you guys can't handle these."

"No problem, just look at us. If it doesn't work, there are teachers to help."

"These are up to you. They are all common sense mechanical principles. I won't worry about it. After you finish the calculations, take out the design drawings. I'm going to study my engine."

After being divided into groups, they began their research work under the leadership of their elected group leaders. Wang Luo was directly responsible for the most important engine.

Time passed unknowingly. Wang Luo rarely went there except for occasionally visiting the pig farm at the accounting school. He devoted himself to this single-cylinder magic machine. When more than half of the summer vacation was over, the first to get good news was the gearbox group. Under the coordination of the coordination group, through the relationship between Principal Lin and Dean Ding, they directly contacted the Changzhou State-owned Wujin Machinery Factory, which was the original designer of S195. They started trial production of 59 diesel engines and Gongnong-1120 hand-held tractors from 7, but they were not put on the market in batches, which means that they were not successful due to poor quality.

But their foundation was quite good, at least they had a foundation, that is, the engine had problems. When the call from the University of Technology came to them, they were very happy. They did not expect that their once unsuccessful product would be valued by the Department of Mechanical Engineering of the University of Technology, which was a high-end professional unit for them.

Their secretary Sun Fuxiang said excitedly: "I never thought that our small factory would receive a call from your university one day. It seems that our original choice was not wrong. Small horsepower tractors have great potential. Unfortunately, our factory's equipment, workers, and R&D capabilities are relatively poor, and the walk-behind tractor we developed was not very successful."

"Then let's cooperate. According to what you said, the main problem is the engine. That's okay. Your gearbox should be fine. If the gearbox is not a problem, we will directly use your gearbox to save us from developing our own, which is too troublesome. If possible, can you pull your unsuccessful tractor over and make a sample for us?"

"Sure, no problem. I'll take the prototype to Beijing right now."

Four days later, Secretary Sun personally brought the tractor to the school-run factory of the University of Technology. They quickly dismantled the gearbox and took a look. They found no problems at all and it could be used. This was a good start.

"Secretary Sun, you have helped our project team a lot. If we had developed the gearbox from scratch, it would have been too time-consuming and laborious. This saves us a lot of time."

Wang Luo said, holding his hand a little excitedly.

"It's good enough that I can help you. I never thought that one day I would be able to bring this machine to a nationally renowned military engineering school. I'm so proud, haha."

After receiving Secretary Sun, the problem of the tractor gearbox was directly solved. After calculation and optimization by the gearbox group, this gearbox can be put into operation directly. Optimization is necessary, otherwise the product quality cannot be guaranteed. After all, the Wujin Factory, that is, Changchai, is still a small factory with only a few pieces of equipment. Everything depends on manual operation and polishing.

"Wang Luo, does your diesel engine need a water tank? The drawings you made don't show the traditional air-cooled design."

"Water cooling is a must. Air cooling is a bit too delicate compared to water cooling. When you are in the fields, what else can you do but repair machines?"

A senior student asked after seeing Wang Luo drawing the blueprint, and Wang Luo also explained it to him.

After giving some pointers to a group of senior students, they carried out the work on the drawing according to Wang Luo's requirements, and Wang Luo found Director Zhao of the school-run factory.

"Director Zhao, this is the cylinder block of the engine. I have marked all the specific parameters on it. Now you can find someone to cast the cylinder block. Try to minimize the error and maintain the output during mass production. So please ask the masters to pay attention to the values ​​in the middle."

Wang Luo took the cylinder drawing and gave it to Director Zhao.

"No problem, just leave it to me. I will ensure that it is completed with quality and quantity, and it will definitely not delay your next work."

Just after he handed in the cylinder block drawings, another senior came to Wang Luo with the drawings. After half a month of getting along day and night, the seniors were impressed by Wang Luo because he knew so much, especially about this single-cylinder diesel engine research and development project. It would be more accurate to say that Wang Luo was pulling them forward rather than saying that everyone was working together.

What they learned from books was often contradicted by reality. Some parts were designed to be a little complicated, and Wang Luo would never agree. They had to be modified because the theoretical processing procedures for many parts could only be processed by machine tools in industrially developed countries such as Europe and the United States. When it came to our country, everything was completely different because there was no separate processing equipment. We could only find alternative methods. Wang Luo not only explained to them, but also pointed out their mistakes and helped them to modify them.

Books are just books. When it comes to real work, you have to adapt to local conditions. Although Wang Luo is their junior, he is more than one level higher than them. He even knows more than their teachers. He knows what parts can be replaced by what equipment during the processing, as if he has an instruction manual in his mind.

They used to call him "Junior Brother", but now they just call him by his name. This brings him to the same starting line as them. I believe that it won't be long before they will call him "Teacher Wang". Hahahaha. Of course, they also learned a lot of practical things at work, because Wang Luo always tells them what he wants to know and patiently tells them if they don't understand.

"Wang Luo, tell me how you use cooling in this place, and why you use so many dome-shaped designs. Look at these places, the cylinder liner, the water tank interface, the water tank waist, all of them are of this structure. What are the benefits of using this structure? I don't think the book mentions this."

"This question is very simple. This machine body is strong, light, and shock-resistant. It is also easy to cast and clean. It also looks good. Using this machine body can at least reduce 4 kilograms compared to traditional machines. If you don't believe me, follow Director Zhao and see how the workers cast it."

Wang Luo answered the question without even raising his head.

"Ah, what else can I do? No, I need to follow and take a look. You go ahead and do your work."

"Go ahead. What's in the books is basically a Da Mao-style teaching material. We are different, so we have to operate according to the situation."

"Thanks."
