Daming Town Haiwang

Chapter 1695, the internal combustion engine came out?

"A brand new power machine?"

"Motor?"

"Or an internal combustion engine?"

On the way, sitting in the four-wheeled carriage, Liu Jin also thought about it.

Based on Daming's current level of technology, whether it is electric motors or internal combustion engines, it seems that it is too early to appear.

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 167s, the Dutch first invented the internal combustion engine using gunpowder as fuel, which made the gunpowder burn and expand in the cylinder. , to push the cylinder to do work.

There is no doubt that this is obviously too much gunpowder to be of practical significance.

It was not until 1801 that the French thought of using gaseous fuels, using coal gas and hydrogen obtained after dry distillation of coal as fuels, which is obviously not very practical.

It was not until 1859 that Belgian engineers developed a two-stroke horizontal internal combustion engine, using liquid fuel, that the technology of internal combustion engines gradually matured.

It was not until 1885 that German engineers developed the gasoline internal combustion engine that the internal combustion engine technology truly matured and began to be operated on a large scale.

As for the invention of the motor, it was also during this period, but it was really mature in the early 20th century.

"It should be internal combustion engine technology."

After thinking about it, Liu Jin can make a rough guess.

"Could it be that I'm too powerful? Daming's technological development is too fast."

"The steam engine was only a dozen years ago, and the internal combustion engine was invented by people. The speed is too fast, and it has traveled a path that others have traveled for hundreds of years."

"It's unbelievable that after more than ten years, this light will be produced, and it will really be like riding a rocket."

"Could it be because of the new type of education I run, under the basic and systematic education and training, the technology and talents are constantly blowing out, so the current effect is achieved?"

Liu Jin kept thinking in his mind.

Soon, Liu Jin and Zhu Houzhao came to the Capital Institute of Mechanical Engineering. When they learned of the arrival of Liu Yuan and Zhu Houzhao, the dean of the college, Ren Siheng, hurriedly brought many deputy deans and professors to welcome them.

"Dean Ren, what kind of power machine was invented just now?"

As soon as he arrived at the School of Mechanical Engineering, Zhu Houzhao hurriedly asked. He was more curious than Liu Jin.

Zhu Houzhao himself is very obsessed with machinery. He has participated in the research of trains and clocks.

"This time, it was a student named Lu Qing from our college. He majored in steam engines. He specialized in the manufacture, research and improvement of steam engines. First boil the water, and whoever turns it on will use the steam to drive the cylinder."

"He wondered why it can't be burned directly in the cylinder, and use the expanding gas to push the cylinder to do work, so that there will be no intermediate loss, which can greatly improve efficiency and generate stronger power at the same time."

While Ren Siheng took Liu Jin and Zhu Houzhao to the laboratory, he also explained to Zhu Houzhao and Liu Jin in detail.

"It burns directly in the cylinder, and uses the expanding gas to push the cylinder."

"Hiss, what a genius idea, why didn't I think of it?"

When Zhu Houzhao heard it, he immediately slapped his brain, and couldn't help being amazed by this unconstrained idea.

"After listening to Lu Qing's idea, the professors in our college felt that this idea was indeed a good idea, so they organized a team to study this technology."

"It really made them come up with some tricks for their research. The power of the researched machine is indeed very strong, much stronger than that of a steam engine."

Ren Siheng also nodded. To be honest, he was also amazed by this idea at first. Someone would think of burning directly in the cylinder and using the expanding gas to push the work.

Soon, under the leadership of Ren Siheng, everyone came to a laboratory of the School of Mechanical Engineering, and saw a large number of professors and students around here, who were researching a strange machine.

This machine is very large, like a small room. It can be clearly seen that there is an oversized cylinder, and there is something like a boiler under the cylinder.

I saw a group of students in disgrace and pitch-black tinkering around on the machine, as if they were doing related repair work.

"Is 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 they can all be made to a small degree. It is not that such huge internal combustion engines do not exist, but are all used on ships.

"Lu Qing, Lu Qing!"

Ren Siheng looked at a young man with a dark face and shouted, and then everyone looked over in unison, 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 was holding a wrench in his hand when he came over.

"Hurry up and tell His Highness the Crown Prince and Mr. Liu about your machine in detail."

Ren Siheng ordered someone to bring a towel and let him wipe his face.

"Yes, yes~"

When Lu Qing heard that the people in front of him were His Royal Highness the Crown Prince and Liu Jin, he quickly wiped his face and began to explain his internal combustion engine in detail.

"I call my machine a lighter. It mainly has two parts. One is the combustion chamber, which is at the bottom of the machine, which is like this big sealed boiler."

"The other part is the cylinder, which is like the piston of a steam engine. When burning in the combustion chamber, a large amount of energy is generated. Under high temperature and high heat, the gas will expand rapidly, and then push the cylinder to do work."

Lu Qing came to the machine and began to explain it in detail.

"Lighter?"

"The name is too low-level."

When Liu Jin heard the name, he was speechless immediately. Can he have some snacks when choosing the name, so he can't take out the name lighter if he chooses it casually.

Take a closer look at the machine in front of you. The combustion chamber is very large, and there is a place next to it that is similar to the feed port, but it needs to be tightened with screws.

"Are you using coal too?"

Liu Jin thought for a while and asked.

"Yes, yes, coal is still used, and coal is added by opening this feed port."

When Lu Qing heard it, he nodded again and again, and then he unscrewed the entrance with great difficulty and showed it to Liu Jin.

"The piston of this cylinder needs to 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 problem with this machine now is that it is inconvenient to add fuel. In addition, because the coal inside is extremely difficult to burn in a sealed environment, it is easy to stop the fire."

"In addition, the combustion of coal is prone to produce a large amount of carbon deposits, which will lead to clogging of cylinders and pistons, and it will not take too long at all."

"In order to solve these problems, we also set up additional air intakes to supply air to the inside, and added fierce fire oil to the coal to support combustion."

When Lu Qing heard it, he also gave Zhu Houzhao a thumbs up. He knew whether there was such a market as soon as he made a move. Everyone knows that His Royal Highness is obsessed with machinery, and now he just asked the key question.

"Then why not just use fierce fire oil for combustion?"

Zhu Houzhao touched his chin and said.

"Yeah, why not burn it directly with fire oil."

"If you use oil directly for combustion, the fuel supply is not a problem. You can directly use a pipe to send oil into it, and continue to burn."

"Furthermore, the combustion of kerosene produces little carbon deposition, and it is easier and more stable to burn than coal."

Hearing Zhu Houzhao's words, Lu Qing immediately yelled and yelled as if suddenly enlightened.

"Yeah, why not burn it directly with oil!"

When many professors and students around heard this, one of them opened their eyes slightly.

They have been studying this for a while, but their thinking has always been limited by the traditional steam engine, and they just want to use the combustion method of the steam engine to study this machine.

Now that Zhu Houzhao woke up like this, they all cried out in surprise.

"If you use strong flame oil to burn, this inlet can be connected with a pipe. There is no need for such a large inlet at all, and there is no need to worry about adding fuel."

"And the combustion of the high-fire oil is easier, more stable, and it can be better controlled. You only need to control the incoming fuel."

"Yes, yes, why can't you use fierce kerosene?"

"This machine doesn't need to be designed so big, it can just be burned directly in the cylinder."

"Yes, yes, this cylinder is the combustion chamber. There is no need for an extra combustion chamber at all, and the cylinder is directly driven by the fierce oil combustion to do work."

"It's much easier to add oil. You can directly install an oil inlet device on the piston to spray the oil in."

"It's a really genius idea and design."

"."

Numerous professors and students immediately started a heated discussion around this internal combustion engine, and even Zhu Houzhao soon joined in. When encountering disagreements, they would argue with each other red-faced.

As for Liu Jin, he was completely left alone, and no one cared about it at all. Ren Siheng unexpectedly joined the heated discussion very quickly, fighting back and forth, and constantly putting forward his own ideas.

"Is this a direct progress from solid fuel to liquid fuel?"

Liu Jin was dumbfounded, and touched his chin. The internal combustion engine felt that it would be mature soon, and it would be ready.
