Siheyuan: My Northeastern Farmhouse

Chapter 182 My surname is Gu, I take care of Gu!

It's no wonder that Qian Weichang has achieved such great achievements. His energy will not be wasted on worldliness!
Gu Weijun patted his head again, "Okay, let's get straight to the point!" "Professor Qian, I'm here to ask for advice on a single-cylinder diesel engine!"

"Oh! Please come in." The fat old man finally let go of the door and welcomed Gu Weijun into the living room.
After sitting down, the fat old man asked directly, "That little classmate" without pouring Gu Weijun a glass of water?

"My surname is Gu!" Gu Weijun had a black line on his forehead.

"Oh! Student Gu, you want to ask about the single-cylinder diesel engine, right? Are you from the mechanical department? How old are you now? This structure is very simple! There is nothing to talk about, right? What question do you want to ask?" The fat old man crackled. After asking a lot of questions, Gu Weijun was given a black line.
Gu Weijun's admiration for the fat old man was gradually crumbling. No wonder Kong Laoer said: Respect ghosts and gods and stay away!This is so close, the idol’s halo has collapsed!You'd better stop pretending to discuss technical issues with the fat old man!Don't let a technical problem lead you to outer space, fat old man, and you won't be able to catch it yourself!
Gu Weijun simply made his request directly: "Professor Qian, if we want to develop a tractor equipped with a single-cylinder diesel engine that can pull 5 or 6 tons of cargo, how much horsepower do you think this single-cylinder diesel engine needs?"

The fat old man's eyes lit up. This question was quite interesting. "Little classmate, wait for me first. I'll get a notebook!"

My surname is Gu!Gu Weijun said to the fat old man again in his heart.
After a while, the fat old man took out a notebook from the bedroom and began to write and draw as if no one was watching, "Engine, chassis, clutch, gearbox, transmission shaft, steering shaft."

"If you want to achieve this traction capacity, according to the formula: T=9550*P/n, the engine is expected to have at least 24 horsepower and a torque of 60Nm. In this case, its stroke must be long and the secondary reduction wheel must be large. It should be "horizontal"

"The clutch and transmission gear are easy to solve, and the diameter of the gear is..."

"The single-cylinder diesel engine needs to be modified. In the current rotation state without increasing the volume, the diesel compression ratio should reach 20:1. In this case, the strength and performance required by the engine cylinder is. The flywheel is..."

Gu Weijun on the side looked stupidly at the fat old man drawing and calculating one by one while talking to himself. In the middle, he quietly poured a glass of water for the fat old man, and quietly put it on the table without daring to say anything.

I don’t know how long it took, but the fat old man looked at the full notebook and stretched with satisfaction, "Well, that’s right, that’s it for the first time! I need to make more precise calculations later, and then build one and try it!" Then He reached out to get a water cup to drink, but when he looked up and saw Gu Weijun, he was stunned. He didn't react for a while, "Little classmate, you are..."

Gu Weijun's eyes were shining and he quickly handed the water cup to the fat old man, pointed at the notebook and said excitedly: "Professor Qian, I'm here to ask about this tractor?"

The fat old man also recalled it at this time, and said apologetically: "Oh, I'm sorry, little classmate, I tend to forget things when I think about things! You are here to ask about the tractor, right? What question do you want to ask?" Afterwards, he waited expectantly. Gu Weijun asked.

Gu Weijun glanced at the notebook. Although he didn't understand it, he saw that you had been writing for so long, muttering some formulas and results, and in the end you were so satisfied with your calculations. Do you still need to ask?No need!
Gu Weijun didn't reply, and silently stretched out his hand to pull the notebook in the fat old man's hand. The first time he pulled it out a little, the fat old man squeezed it hard with both hands.Gu Weijun tugged again, but the notebook didn't move. The fat old man looked down at the notebook, then looked up at Gu Weijun, full of confusion, "Little classmate, didn't you want to ask me a question?"

"Ahem!" Gu Weijun coughed awkwardly, released his hand as if nothing had happened, and pointed at the notebook, "What about that? Professor Qian, you have already answered my question! Didn't you already put together the drawings of a walking tractor towing about 5 tons? Have you painted it yet? This is what I need!"

"Bang!" The fat old man immediately changed his face and slammed the table hard, startling Gu Weijun.

Next, the fat old man criticized Gu Weijun very seriously, "How come you, a little classmate, don't have the spirit to learn at all?" "What kind of learning attitude do you have?"

The fat old man pointed at the notebook angrily, "Is this the result of your study and research?" "Is this the result of your hard thinking?"

The fat old man took a deep breath and spoke earnestly to Gu Weijun, "Little classmate, I remember you are a student at Tsinghua University, right? You should put all your energy into your studies! It doesn't matter if we don't have it now, but the spirit of study and research cannot be lost. ! The country’s future construction depends on you!”

The fat old man tore off a piece of paper from his notebook and handed the pen to Gu Weijun, "Come, sit here, and I will explain to you the structure and principles of this single-cylinder diesel engine from the beginning!"

"Ah!" Gu Weijun was dumbfounded and subconsciously glanced at the wall clock. It was already past 8 p.m. Old comrade, you have no need, but I am still young and still have plenty of energy, right?It’s Saturday, and I’m still looking forward to the red sleeves adding fragrance.
Seeing Gu Weijun still standing stupidly, the fat old man handed over the pen and paper again and angrily said, "Why are you still standing stupidly? Sit there and listen!"

At this point, Gu Weijun could only sit on the side obediently and listen to the fat old man explain starting from the principle of a single-cylinder diesel engine, "A single-cylinder diesel engine is a compression ignition type, and its structure is divided into several parts."

"Who am I? Where am I? What am I doing?" After three consecutive rounds, Gu Weijun could only take pleasure in the hardships and comfort himself, what a guide for one of the three coins!It’s one-on-one face-to-face!Who can have this opportunity?If there is such an opportunity in future generations, no matter how bad I am, I will still be a 211 graduate.
But that’s not necessarily the case. Didn’t Professor Ding, a professor at Peking University, compromise on his daughter’s education? “This is the way of heaven. There is no other way. You have to accept it. What will happen if you don’t accept it? That’s how she is.”

"Bah!" Seeing Gu Weijun distracted, the fat old man hit him as soon as he was distracted, "You dare to be distracted!" Gu Weijun didn't dare to hide even if he could. As long as he continued to listen carefully, the fat old man continued to listen until about 11 o'clock in the middle of the night. The old man ended the explanation temporarily without finishing his thoughts, "Well, let's do this for today. I won't talk much today, how about it? Do you understand everything?"

Gu Weijun looked up at the wall clock again and nodded blankly.Isn't this called much?Old money, do you have no idea about how much?
The fat old man is very satisfied, the boy can be taught!After-school homework was immediately arranged, "This way, you can write me a paper on what I will explain today next Saturday!"

"Well, the topic is called Ways to Improve the Power Output Efficiency of Single-Cylinder Diesel Engines!"

"Ah!" Gu Weijun's eyes widened, fat old man, are you a devil?You just gave me a lecture and then asked me to write a paper?
Looking at Gu Weijun's expression, the fat old man's criticism immediately came, "How come you, a little classmate, are so unmotivated to study! I will make a book list for you. You can refer to it tomorrow!" Then he put pen to paper and wrote a few books. After tearing off the title of the book, he handed it to Gu Weijun, "These books are all in Tsinghua University's library!"

"Oh!" Gu Weijun took the book list and felt dizzy. They were basically Soviet books about engines, such as "Purification of Car and Tractor Engine Oil and Fuel", "Diesel Engine Manual", etc. Did he already think that he could read in Russian?

"Okay, let's go quickly, I want to rest!" The fat old man didn't care whether Gu Weijun was dizzy or not, he just hit him.

Gu Weijun walked to the door with a wry smile, turned around and introduced himself again: "Professor Qian, my surname is Gu, I take care of Gu!"
