Siheyuan Great Craftsmen

If you want to do it, just do it. Soon, he took out the blueprint and began to draw the structural design of the tractor.

This year, that is, 1952, the country will promulgate some reform policies regarding agricultural mutual assistance, and he can take advantage of this favorable situation to promote his agricultural machinery.

He originally planned to start with some basic research objects, but after much thought, he decided to start with the tractor. After all, compared with other daily machinery, the tractor is undoubtedly the most helpful to farmers.

Tractors are generally divided into crawler tractors and wheeled tractors, each of which has its own advantages and disadvantages.

If you want to study tractors, you can't avoid studying diesel engines.

At this time, the diesel engines in domestic tractors mostly had power ranging from tens to several kilowatts, with a maximum power of only 24 horsepower.

Compared with the 54-horsepower diesel engine of the foreign big brother, the gap is really big. Of course, this has a lot to do with the fact that the big brother's diesel engine is a four-cylinder one.

What we are talking about here is only the diesel engine of the tractor, not the diesel engine on the airplane. After all, the diesel engine on the airplane is much more powerful than the ordinary diesel engine and is not on the same level.

The structural drawings of a tractor are not complicated to draw. On the contrary, the drawings of a diesel engine are much more complicated. They consist of nine parts: cylinder block and cylinder head, piston, piston ring and piston pin, connecting rod and crankshaft, camshaft and valves, fuel system, cooling system, lubrication system, starting system and electrical system.

As Zhou Tian continued to draw the structure of the diesel engine, a stream of information instantly flooded into his mind. At the same time, a diesel engine different from the current one appeared in the virtual space of his mind.

"Boy, this diesel engine is really powerful!"

When he had digested all the information in his mind, he couldn't help but exclaim to himself.

This diesel engine that came from the virtual space in his mind was actually a single-cylinder diesel engine with a power of 36 horsepower. Compared with the domestic 24-horsepower diesel engine, it is much more powerful and is comparable to the HS400 diesel engine of the s.

Of course, it is strong, but the manufacturing difficulty is also rising sharply. The steel required for the cylinder alone is not something that ordinary steel can achieve. Not only must it have high strength and good wear resistance, but it also needs to have extremely stable thermal stability.

Fortunately, the specific manufacturing method of the diesel engine is given in the virtual space, as well as the specific description and metallurgical formula of its cylinder material.

With the formula and metallurgical description, Zhou Tian also completely understood why the materials used in current diesel engines frequently malfunction. To put it bluntly, it is because the cylinder material does not match.

However, it is clearly stated on the cylinder block material in the virtual space in my mind that the cylinder block of this engine needs to be made of vermicular cast iron.

He did know a little about vermicular graphite cast iron. It seemed that in 1947, Morrow from England accidentally discovered vermicular graphite while studying ductile iron. It was not until the 20s that the Orleys studied the effect of rare earths on molten iron and finally determined the formula of vermicular graphite cast iron. In 60, they obtained a patent for the production of vermicular graphite cast iron.

At present, vermicular cast iron has not attracted the attention of foreign countries. If he develops vermicular cast iron now, wouldn't he be able to seize the patent of vermicular cast iron? Moreover, vermicular cast iron is widely used in the manufacture of diesel engine cylinders in later generations, which can be called a golden hen that lays eggs.

Although he may not be able to collect any patent fees even if he develops vermicular cast iron now, it does not mean that he cannot collect them in the future. Thinking of this, Zhou Tian's heart moved, and he wrote down the formula and process of vermicular cast iron on the drawing. After writing it, he finished drawing the design of the diesel engine, and then he got up and left the steel rolling mill and went to the machinery factory.

When he arrived at the machinery factory, he first asked the guard about Song Weiguo's whereabouts. When he learned that Song Weiguo had not returned from the military factory yet, he was slightly disappointed and rode his bike back to the steel rolling mill.

As soon as Zhou Tian returned to the steel mill, he saw Nie Guodong pacing back and forth at the factory gate. When he saw Zhou Tian coming back, his eyes immediately flashed with light, and he hurriedly came up to him and said, "Xiaotian, where did you go just now? I went to your office to look for you, and your technical department said you had left!"

"Chief, what do you want to talk to me about?"

Seeing Nie Guodong's anxious face, Zhou Tian couldn't help but ask curiously.

"Of course there is something wrong. Let's go and talk while we walk!"

As he spoke, Nie Guodong took Zhou Tian's hand and walked into the steel mill.

"Hey, hey, hey! Chief, slow down, I'm still pushing my bike, if you keep pulling like this, I won't be able to move!"

Hearing this, Nie Guodong stopped and looked at Zhou Tian struggling to push the cart with one hand. He couldn't help but smile and said, "Why don't you hurry up and catch up!"

Zhou Tian rolled his eyes speechlessly. He wanted to follow, but how could he follow after what he did just now? He complained in his heart, and he said no more. The two of them entered the steel rolling mill and came to the logistics department.

Zhou Tian parked the car in front of the logistics department, and he and Nie Guodong walked into his office one after another.

"Xiaotian, you have to help me with this matter, otherwise I don't know what to do."

After the two sat down, Nie Guodong poured Zhou Tian a cup of tea and said with a worried look.

"Hey, Chief, please tell me what's going on. I'm still confused and you dragged me to the logistics department!"

Listening to Nie Guodong's words, Zhou Tian said speechlessly.

"Look at me, I'm so anxious that I'm confused. Xiaotian, I know you know He Daqing, I want you to ask him, is there any chef in our city who can make Western food?"

"Western chef?"

Zhou Tian had been wondering along the way what had happened to make the section chief so anxious, but he didn't expect it to be this. He was even more confused for a moment.

"No, Chief, why are you looking for me so urgently just for this matter?"

"Isn't this a big deal?" Nie Guodong glared at him and said, "The superiors asked our factory to be responsible for the food and daily life of these senior experts. Housing is easy to solve, as they have an expert building allocated by the state, but the problem is that it is difficult to arrange food!"

As he spoke, Nie Guodong couldn't help but sigh.

If it was the Eight Great Restaurants, even if it was bird's nest or ginseng, as long as they had it, he could have people collect it and make it, but the problem was Western food, which the Eight Great Restaurants didn't have and couldn't make. This gave Nie Guodong a headache.

"Section Chief, you are the head of the logistics department. Can't you call Uncle He to ask yourself? Why do you have to let me ask? Isn't this unnecessary?"

Zhou Tian could understand the section chief's complaints, but he didn't understand why he didn't ask He Daqing, but asked him instead. Isn't this like asking a blind man for advice? Moreover, Uncle He was theoretically under the section chief's jurisdiction, so he didn't understand why he didn't ask He Daqing himself.

"Hey, you think I don't want to, but He Daqing is a very reckless person. It's not like I haven't been there before, but he rejected me!"

Nie Guodong couldn't help but roll his eyes at Zhou Tian and sighed.

"What? No way!"

Zhou Tian was stunned by Nie Guodong's words. Uncle He dared to do this? He couldn't believe it.

If it was Sha Zhu in the plot, he would believe it, but He Daqing is the director of the cafeteria, and he dared to directly refuse his immediate superior. He felt that Uncle He should not be so brainless!
