Chapter 1696, the internal combustion engine came out?
"A brand new power machine?"
"Electric motor?"
"Or an internal combustion engine?"
On the road, sitting in the four-wheeled carriage, Liu Jin also started thinking.
Judging from the current technological level of the Ming Dynasty, whether it is an electric motor or an internal combustion engine, it seems that they appeared too early.
Historically, the steam engine was invented around 1700 and the technology became mature, while the development of the internal combustion engine went through three stages. In the 1670s, the Dutch first invented an internal combustion engine that used gunpowder as fuel, causing the gunpowder to burn and expand in the cylinder.
, push the cylinder to do work.
There is no doubt that this is obviously too wasteful and of no practical significance.
It was not until 1801 that the French thought of using gaseous fuel, using coal gas and hydrogen obtained after the carbonization of coal as fuel. This was obviously not very practical.
It was not until 1859 that Belgian engineers developed a two-stroke horizontal internal combustion engine that used liquid fuel, and the internal combustion engine technology gradually became mature.
It was not until 1885, when German engineers developed the gasoline internal combustion engine, that the internal combustion engine technology truly matured and began to be put into large-scale operation.
As for the invention of the motor, it was also during this period, but it really matured in the early 20th century.
"It should be internal combustion engine technology."
Liu Jin thought about it and was able to make a rough guess.
"Am I cheating too much? Ming's technology is developing too fast."
"The steam engine only took more than ten years, and the internal combustion engine was invented. The speed was too fast, and it has traveled a road that others took hundreds of years to travel."
"We can't afford to think that in more than ten years, all these lamps will be built, and it will really be like riding a rocket."
"Is it because I run a new type of education? Under the basic and systematic education and training, the technology and talents have continued to explode, so the current results are achieved?"
Liu Jin kept thinking in his mind.
Soon, Liu Jin and Zhu Houzhao arrived at the Beijing Mechanical College. Upon learning of the arrival of Liu Yuan and Zhu Houzhao, the dean of the college, Ren Siheng, also hurriedly brought many deputy deans and professors to greet them.
"Dean Ren, what kind of power machine has been invented just now?"
As soon as he arrived at the Mechanical College, Zhu Houzhao quickly asked. He was even more curious than Liu Jin.
Zhu Houzhao himself was very obsessed with machinery. He participated in the research of trains and clocks. His obsession with various machinery can be said to be second only to the creation of humans.
"This time it was a student named Lu Qing from our college. He studied steam engines, specializing in the manufacture, research and improvement of steam engines. After studying steam engines, he suddenly had a whim, saying that this steam engine actually consumes a lot of energy and requires
Boil the water first, and then use the steam to push the cylinder."
"He wondered why the combustion could not be carried out directly in the cylinder, and the expanded gas could be used to push the cylinder to do work. In this way, there would be no intermediate losses, which could greatly improve efficiency and produce stronger power."
Ren Siheng took Liu Jin and Zhu Houzhao to the laboratory and explained it to Zhu Houzhao and Liu Jin in detail.
"Combust directly in the cylinder and use the expanding gas to push the cylinder."
"Hey, what a genius idea, why didn't I think of it?"
When Zhu Houzhao heard this, he immediately patted his brain and couldn't help but be amazed by this unreasonable idea.
"After listening to Lu Qing's idea, the professors in our college felt that it was indeed a good idea, so they organized a team to study this technology."
"They really worked out some tricks. The machine they developed is indeed very powerful, much more powerful than a steam engine."
Ren Siheng also nodded. To be honest, he was surprised by this idea at first. Someone would actually think of burning directly in the cylinder and using the expanding gas to promote work.
Soon, under the leadership of Ren Siheng, everyone arrived at a laboratory in the School of Mechanical Engineering. They saw a large number of professors and students surrounding the place, working on a strange machine.
This machine is very large, like a small room. You can clearly see that there is an oversized cylinder, and underneath the cylinder is something like a boiler.
I saw a group of students with gray faces and dark faces, tinkering around on the machinery, seemingly carrying out related repair work.
"Isn't this too big?"
Liu Jin looked at the big guy in front of him and was slightly dumbfounded. This was the first time he had seen such a huge internal combustion engine.
The technology of internal combustion engines in later generations has been extremely advanced and can be made to a very small extent. It is not that there are no such huge internal combustion engines, but they are all used on ships.
"Lu Qing, Lu Qing!"
Ren Siheng looked at a young man with a dark face and shouted. Then everyone looked over and soon knew that the prince and Liu Jin were coming.
"Dean~"
Lu Qing was a young man of eighteen or nineteen years old, and he had a wrench in his hand when he came over.
"Hurry up and tell His Royal Highness the Prince and Mr. Liu about this machine of yours in detail."
Ren Siheng ordered someone to bring a towel and asked him to wipe his face.
"Yes, yes~"
When Lu Qing heard that the people in front of him were His Highness the Crown Prince and Liu Jin, he immediately wiped his face and began to explain his internal combustion engine in detail.
"I call this machine a lighter. It mainly consists of two parts. One is the combustion chamber. At the bottom of the machine, it is like a large sealed boiler."
"The other part is the cylinder, which is just like the piston of a steam engine. When burning in the combustion chamber, a large amount of energy is generated. Under high temperature and heat, the gas will expand rapidly, thereby pushing the cylinder to do work."
Lu Qing came to the machine, gestured with it and explained it in detail.
"Lighter?"
"This name is too poor."
When Liu Jin heard the name, he was immediately speechless. Can you please give me some snacks when you pick the name? You can pick it casually and you won't come up with the name "Lighter".
Take a closer look at the machine in front of you. The combustion chamber is very large, and there is a place similar to the feed port next to it. But the good thing is that it needs to be tightened with screws.
“Are you also using coal?”
Liu Jin thought for a while and asked.
"Yes, yes, we still use coal. Open this feed port and add coal in."
When Lu Qing heard this, he nodded repeatedly, then struggled to unscrew the entrance and showed it to Liu Jin.
"The cylinder piston must be sealed to have greater power. If you seal it, how can the coal burn?"
Zhu Houzhao walked around the machine, thought for a while and said.
"Your Highness is amazing. You can see the problem with my machine at a glance."
"The current problem with this machine is that it is inconvenient to add fuel. In addition, because of the sealed environment, the coal inside is extremely difficult to burn, and it can easily stop burning."
"In addition, coal combustion easily produces a large amount of carbon deposits, which causes the cylinder and piston to become clogged, so it won't last too long at all."
"In order to solve these problems, we also set up additional air inlets to supply air inside, and added fire oil to the coal to support combustion."
When Lu Qing heard this, he also gave Zhu Houzhao a thumbs up. He knew it as soon as he made the move. Everyone knew that His Highness the Prince was obsessed with machinery. Now he just asked the key question.
"Then why not just use fire oil to burn it?"
Zhu Houzhao touched his chin and said.
"Yeah, why not just use strong fire oil to burn it."
"If you use oil directly to burn, the fuel supply will not be a problem. You can directly use a pipe to send oil inside, and the combustion will continue."
"Furthermore, the burning of fire oil produces very little carbon deposits, making it easier and more stable to burn than coal."
After hearing Zhu Houzhao's words, Lu Qing suddenly shouted as if enlightened and shouted.
"Yeah, why not just use oil to burn it!"
Upon hearing this, many professors and students around him suddenly opened their eyes slightly.
They have been studying this for some time, but their thinking has been limited by traditional steam engines. They just want to use the combustion method of steam engines to study this machine.
Now that Zhu Houzhao woke up like this, everyone screamed in surprise.
"If you use strong fire oil to burn, this inlet can be connected with a pipe. There is no need for such a large inlet, and there is no need to worry about adding fuel."
"Furthermore, the combustion of fierce fire oil is easier, more stable, and can be better controlled. You only need to control the incoming fuel."
"Yes, yes, why can't we use strong fire oil?"
"This machine does not need to be designed to be so large. It can simply be placed directly in the cylinder for combustion."
"Yes, yes, this cylinder is the combustion chamber. There is no need for an extra combustion chamber. The strong combustion of fuel directly drives the cylinder to do work."
"It is much easier to add oil. You can set up an oil inlet device directly on the piston to spray the oil in."
“This is truly a genius idea and design.”
""
Many professors and students immediately started a heated discussion around this internal combustion engine. Even Zhu Houzhao soon joined in. When they met those with different opinions, they would argue with each other.
As for Liu Jin, he was completely ignored and no one cared about it. Ren Siheng quickly joined the heated discussion, arguing and constantly putting forward his own ideas.
"Is this a direct progression from solid fuel to liquid fuel?"
Liu Jin was dumbfounded and touched his chin. It felt like the internal combustion engine would soon be mature and ready for use.
