Chapter 1512, Internal Combustion Engines and Decomposing Petroleum
"It's very good. We must continue to carry it forward, continue to explore, and continue to innovate!"
After listening to He Wenyuan's report, Liu Jin also gave a positive evaluation, and his money was finally not wasted.
From now on, when writing the history of the development of science and technology, it is estimated that the names of scientists and inventors of the Ming Dynasty will be written in the future, so that they will not be evaluated as having no contribution to modern science like later generations.
Nonsense~
The descendants of the Yan and Huang Dynasties are the most outstanding nation in the world. As long as they do not close themselves off to the country and are not arrogant, they will always be the top of the world's powerful nations.
With just a little guidance from him, Ming Dynasty's technological development has made rapid progress and achieved rapid development. Liu Jin believes that it will not take too long to use the starting light.
"Yes~"
Upon hearing this, Huang Chong, He Wenyuan and others nodded quickly and took note of Liu Jin's words.
The educational field of the Ming Dynasty was originally dominated by traditional Confucianism, and there was no room for the survival of any other schools or theories. The main reason why the New School was able to rise and develop rapidly was because the New School focused on applying what was learned.
That is, what is learned and researched will eventually be used in life and production. Whether it is the content taught in basic elementary schools, middle schools, or colleges and universities, everything revolves around
This comes from this.
It can be seen from the arrangement of teaching content that new students may not be able to write poetry or eight-legged essays, nor can they recite too many Tang poems and Song lyrics or the Four Books and Five Classics.
But they learn a lot of things, basic mathematics, addition, subtraction, multiplication and division are the most basic, simple solid geometry, basic unit conversion, etc. These are all very useful.
In addition, geographical knowledge, historical knowledge, etc., are all basic and can allow students to understand the world from childhood to adulthood, know their place in the world, know the dynasty they are in now, and know their own history.
.
The teaching philosophy is based on practicality. Although they cannot take the imperial examination to gain fame and become officials, the students who have passed through the new studies have mastered a lot of practical knowledge, which can be applied in various fields casually, and they are very popular.
When it comes to colleges and universities, they focus on integrating theory and practice, focusing on exploration, research and innovation, so as to use knowledge to serve life and production. Many important inventions have emerged and promoted the development of the Ming Dynasty.
"I came here today mainly because I have two tasks for you."
"Please contact Daming Royal Institute of Technology, Beijing Institute of Mechanical Engineering and Imperial University. The four universities will join forces to help me research two things."
Liu Jin explained the purpose of coming to Imperial College today.
"Please give me your instructions, Mr. Liu~"
After hearing Liu Jin's words, several people immediately became energetic.
Generally, the things Liu Jin is asked to study are very important things, and they are also good opportunities to make a name for themselves.
Like steam engines, steam trains and steam ships, when they first came out, they were directly received and rewarded by the emperor, and the main people in charge were directly awarded knighthoods. This is absolutely a supreme honor.
You must know that even for traditional scholars, it is not easy for them to obtain a knighthood. Only those who are extremely respected and have made many great contributions can be knighted. For example, Liu Jian, the chief minister of the cabinet, got the title
It is a title, but it is not hereditary.
It can be seen that it is definitely not easy to obtain a title in the Ming Dynasty. Apart from military merit, there are too few other titles.
The emergence of steam trains brought extraordinary significance to the Ming Dynasty. The entire team was received by the emperor, and some people received knighthoods. This was a huge encouragement to the craftsmen and researchers of the Ming Dynasty.
"One is to study internal combustion engines~"
"One is to study the separation of oil~"
"internal combustion engine?"
"What is an internal combustion engine?"
"This oil seems to be fire oil. Can it be separated?"
After hearing the two new terms mentioned by Liu Jin, three professors, He Wenyuan, Xie Geng, and Ding Zhixiang, quickly asked.
Huang Chong is the principal, but he is not responsible for scientific research. The three professors are mainly responsible for scientific research, so they are very sensitive to these things.
"The main power we use now is the steam engine. The steam engine relies on the steam after boiling water to push the piston to provide power. We can call it a steam engine."
Liu Jin also quickly explained.
"But the energy loss of this steam engine is relatively serious, because water needs to be heated and converted into steam, and the steam then pushes the piston to rotate and drive the machine."
"And as our research on steam engines continues to deepen, we find that after the power of a steam engine reaches a certain level, it is difficult to improve it."
"It's true. The energy loss of steam engines is very large. Steam trains require a very large amount of coal. Moreover, the power of the steam engines we have manufactured has never been able to make a leap forward and be used in steam ships.
It’s the most powerful steam engine ever built.”
Xie Geng mainly studies steam engines. After listening to Liu Jin's words, he also deeply agreed.
"So I thought, can we directly develop a machine that burns directly in the sealed machine cylinder, and relies on the heat energy generated during combustion to push the piston to work? We can call this machine an internal combustion engine!"
"Combustion directly in a sealed cylinder?"
"This is impossible. How can it burn without fire?"
"And this combustion requires firewood or coal. When burned in a sealed environment, the ash left behind will be discharged. The piston cylinder will soon be worn out by these ashes."
"Yes, yes, and in a sealed environment, the gas will be exhausted quickly. Without gas, it will not burn at all."
"This is impossible, this is impossible~"
When Xie Geng heard this, he immediately shook his head. In this era where steam engines have just started to develop, it seems a bit impossible to use internal combustion engines.
"Don't say too much~"
"This combustion does not necessarily require the use of firewood or coal. Whale oil can be burned. It has no ash, is stable, and has high energy."
"As for gas, you can add more air intake pipes. After burning, you can inhale it and soon there will be gas. As for fire, we conducted experiments. In a high-temperature and high-pressure environment, combustion is a very simple matter. Electromagnetic sparks can be used to ignite the fire.
, it is very clear to achieve high temperature and high pressure in the piston cylinder.”
Ding Zhixiang, who was on the side, thought for a while and said, he felt that this internal combustion engine is still possible in theory.
"If such an internal combustion engine can really be built and uses high-enhanced materials for combustion, theoretically speaking, it can easily surpass the steam engine."
He Wenyuan thought for a while and nodded.
"In addition, is the decomposition of oil related to this internal combustion engine?"
"Petroleum is also called fire oil. It burns very quickly, the temperature is very high when it burns, and it is very difficult to extinguish."
"Yes, there is a certain relationship between petroleum and internal combustion engines. Petroleum is an ideal combustion raw material, but it can not only be used for combustion, it is also an extremely important chemical raw material."
"If oil is simply used for burning, it would be such a waste."
"Petroleum or chemical materials?"
Professor Xie Geng asked very puzzledly.
"This needs to be studied by professional people like you. I have heard it proposed. I heard that in Europe, they had records of using oil hundreds of years ago."
Liu Jin looked at the professors who were staring at him, and suddenly his heart skipped a beat. It seemed that he couldn't talk too much. There were some things he could guide, but he couldn't tell them all, otherwise his identity as a time traveler would be easily exposed. Of course,
Although no one believes in such a mysterious thing as time travel, they still can't explain why they know that internal combustion and oil can be decomposed.
After thinking about it, I can only leave this blame to the Europeans. Anyway, after having more contact with other parts of the world, the Ming people also discovered that Europeans also have very amazing performance in many fields such as mathematics, astronomy, geography, machinery, etc.
It seems reasonable for them to take the blame.
"I see. I've heard about it. It's said that in ancient Greece, people used this oil to fight wars. They filled the river with oil, and after the other party's ships came over, they lit the oil. This oil is worthy of being called fire oil.
It can also burn on water."
Xie Geng, He Wenyuan, and Ding Zhixiang suddenly understood. Xie Geng even helped Liu Jin smooth things over by talking about things recorded in some foreign classics that he had read.
"Liu Gong, please feel free to leave this matter to us. We will definitely invest a lot of manpower and funds into research and we will definitely satisfy you."
Huang Chong looked at the three professors and assured Liu Jin.
"Then I'll help you. There's no need to rush this. It doesn't matter if you study it slowly. It's a very complex and systematic thing. Explore more, summarize more, and take your time."
"On the contrary, we can focus on studying the decomposition of oil first."
Liu Jin is not very anxious about internal combustion engines. Now that a steam engine is available, it is almost enough. What is more urgent now is the decomposition of petroleum. If petroleum can be decomposed, many chemical raw materials derived from petroleum can be obtained in large quantities. The most important one is that it can be used
Manufacture tires.
It is still a bit too luxurious to make tires with natural rubber, and the price of rubber is getting higher and higher, and the output is always limited, which is difficult to meet the current demand. In the end, we still have to rely on the decomposition of petroleum to produce artificial rubber to meet the needs of industrialization. In addition, industrial production is absolutely
Inseparable from petroleum, its uses are too extensive and too important.
