Yang Yuanzhao is an engine engineer, and he is quite familiar with the tractor structure. It is very difficult to apply a small BMW 999 engine to a tractor, even if he is experienced.

After thinking for a long time, Yang Yuanzhao slowly straightened his thoughts and added some things to the engine that can only be used in high-end cars. He completed mechanical transmissions and power equipment, and the most important thing was the engine and transmission device. After completing this, in Yang Yuanzhao's view, the entire design was mostly done, and the rest was the appearance and operating system.

Later generations Yang Yuanzhao saw many tractors. Relatively speaking, small ones are not suitable for large farms like Baotou. Baotou has thousands of miles of fertile land. Although the 220 hectares of land are not connected together, they are only divided into two pieces of size and size, belonging to two large landlords. Obviously, when they chose the land, they specially integrated it, so the land of Baoken Company is two large tracts of land, each of which exceeds 10,000 acres. It can be said that it is a real big farm.

Since it is a large farm and it can play its best, it can only be a large, large tractor, and the BMW 999's 193 horsepower, which is barely possible. Tires are a big problem, and huge tires are definitely a roadblock.

In this era, vulcanized rubber technology has appeared, but to a certain extent, this technology is high-tech. In the early 20th century, the United States already owned a large number of cars. The famous Ford relied on the T-shaped model, the cheapest model of the epoch-making model, and became one of the guides of the American automobile industry. The Ford family also began its rise. However, even Ford did not use tires in the true sense. It used gun wheels, that is, wooden. Most of the cars born in this era, either used wood or tires wrapped in a layer of rubber or other things, and inflatable tires. To a certain extent, it was still a fantasy that it would not be used on cars until almost 20 years later.

The all-in-one machine is very powerful, but it cannot make things out of thin air. In Yang Yuanzhao's view, rubber may also be a kind of organic matter. It is really hard to say whether it can be copied. So he has only one choice.

Crawler-type and crawler-type tractors are the foundation of tanks to a certain extent. They will not develop tremendously until 10 or 20 years later, or even during World War II. They will only develop rapidly after World War II. Generally, crawlers are among large-scale machinery, such as large excavators, bulldozers, etc.

The track type is Yang Yuanzhao has been exposed to. The early track type was very simple, regardless of speed, but only considering the efficiency and function of entering the farmland. The track type is still acceptable. The huge area of ​​stress will make the bulldozer reduce the pressure on the land by the bulldozer, which is conducive to the further improvement of its functions.

It seems that I have been walking in the horn before, and the crawler type can also be solved. The crawler type is nothing more than using a transmission device to run the crawler wrapped outside. Under the premise that large tires and special tires are not solved, the crawler type is a necessary device for tanks. It divides the pressure of dozens of tons of tanks onto huge crawlers, which has little pressure on land and roads. The most important thing is that it can pass through most of the environment on the battlefield, especially the battlefield environment full of craters and obstacles. For example, trenches that do not exceed the overall length of the vehicle, some slightly steep slopes, and some not-too-high steps, can all pass through.

In this era, was the use of crawlers a little earlier? Yang Yuanzhao thought carefully that the crawlers are probably the only key to solving the tractor problem. Recalling, after calculating several problems, he found that he did not have much contact with crawlers, but he could barely make them. Perhaps in terms of speed and flexibility, it was far from the crawlers in later generations, but it was much higher than in this era.

Since the chassis problem was solved with crawler type, we would not consider the tire problem. The rest is to integrate the entire collective, use some fixed structures to imagine all the components of the tractor, and carefully checked it, without any omissions. Yang Yuanzhao then asked: "Dingdang, how do I want to generate the drawings, or do I imagine it directly?"

"Yes!" Dingdang replied affirmatively.

Yang Yuanzhao began to outline the drawings of the tractor in his mind, which looked a little strange, but could achieve the full effect of the tractor. It took almost 10 minutes and finally completed the entire outline process. He thought he could successfully complete the copying of the drawings, but at the moment when the drawings were generated, a purple light suddenly turned ahead, and the drawings turned into ashes out of thin air.

"This, what is this?"

"Verification failed!" Dingdang said calmly.

"If you fail, why did you fail?" Yang Yuanzhao said a little lost.

"Of course, according to the drawings you imagined, even 30% of the tractor cannot be completed, how can it be passed?" Dingdang's words were calm and unceremonious, which made Yang Yuanzhao feel ashamed. Yes, he was not familiar with the tractor. He just barely completed the imagination of different components of the tractor based on the mechanical principles. He integrated it together and looked strange. If he succeeded, he might not be able to last for a long time. What's more, the overall 30% could not be completed.

Yang Yuanzhao looked at the empty space and asked in his heart: "Dingdang, how can I improve my completion level!"

"This, according to the rules, I can't guide you!"

Dingdang's words made Yang Yuanzhao feel a little disappointed, but when he looked up, he saw the smile on the corner of Dingdang's mouth, and suddenly said, "What am I going to do now!"

"Didn't you have a book about engines? Go and try it!" Dingdang said casually, but made Yang Yuanzhao understand. Dingdang might be because of some rules that cannot directly guide him. No matter how to improve it, it cannot be done, but if you change the question, you can find the answer.

When I came here, I was wrapped in an all-in-one machine and brought a lot of things, including a small bookshelves next to the workbench. There were some reference books on it, most of which were the whole engine.

After leaving the drawing area, Yang Yuanzhao searched on the small bookshelf and quickly found the book, the history of engines and cars, and the detailed narrative, starting with Watt's improved steam engine, the history of engine development. Among them, there are some drawings, although they are just simple and simple drawings, but they gave Yang Yuanzhao a great inspiration, especially later, based on the engine after the founding of the People's Republic of China, which discusses the specific development history of the engine in detail, and the things about the engine are all mentioned in detail.

Obviously, if you want to determine the success rate, this book is a breakthrough. With this book, you quickly turned to the principle of Watt Steam Engine. After Yang Yuanzhao had some imagination, he began to enter the drawing area and began to verify the new drawings.

Watt's improved steam engine is far older than this era than Yang Yuanzhao's era. According to some descriptions in the book and his imagination, Yang Yuanzhao formed the drawings, the light flashed again and failed again.

This failure did not discourage Yang Yuanzhao, but instead remained calm and continued to verify other drawings. The whole book, more than 30 different engines, passed the verification in total, and 5 were formed, and the others failed without exception.

Yang Yuanzhao was delighted. He finally found the reason. Regardless of whether the engine was advanced or not, it was like Watt's steam engine. At the beginning, the diesel engine was the same as the internal combustion engine. In this era, some people have made it in foreign countries. It can be said that the technological content is very low. However, Yang Yuanzhao still did not make it. The reason was that he was not familiar with it. On the contrary, the old Jiefang 88-horsepower engine, Santana engine, two-stroke and four-stroke motorcycle engines successfully completed the drawings.

What does this mean? The drawings are more based on familiarity. In terms of the engine level, whether it is the old Jiefang 88-horse engine, Santana, or even the two-stroke and four-stroke motorcycle engine, his performance indicators are much stronger than the engines of this era, but they succeeded because, whether in school or after graduation, Yang Yuanzhao was almost always in contact with these engines, and even familiar with every part of them. With the help of this book, the memories were clear, and then he successfully verified. As for other things, even the simplest Watt engine, he could not generate drawings out of thin air.

Yang Yuanzhao smiled bitterly. The reason for the failure of the tractor was found before was found. With the BMW 999 engine, this is a motorcycle engine after all. The structure of the tractor is simple. However, if the BMW 999 engine is applied to the tractor, there are many things that need to be changed. He almost didn't understand the many things, so it is normal to fail.

It seems that the idea of ​​designing a tractor directly on the train was basically a failure. After all, he did not have a diesel engine with a qualified tractor and could not borrow the previous mechanical structure. The changes he made may be, or may not be, and he must rely on step-by-step experiments to complete the setup. This is also the fundamental reason for his failure in the drawings.

Unfortunately, although it is impossible to use the BMW 999 engine to complete the transformation and installation of the tractor, I unexpectedly obtained the drawings of the five engines. Although it is only manufacturing drawings and no material drawings, the engine produced in this way will have some gaps with the original ones in many aspects. However, with the treasure house of BMW 999 engine, it is not impossible to solve after using what I have figured out.

After finding the reason, Yang Yuanzhao calmed down. For the time being, the tractor could only be studied. Fortunately, the engine and the chassis are almost the same. It is just that the various components of the tractor, the combined harvester and the mechanized part are not particularly familiar. The pictures seen in later generations must be continued to be considered before they can be completed.

It seems that only when you have to go back to Baotou can you conduct the next experiment. Only by slowly changing in actual operations can the tractor be formed. Without completing the entire drawing at once, it has also achieved many results. To a certain extent, he has straightened his ideas.
