Liu Jin took Zhu Houzhao to a building in the Beijing Machinery Factory, which Liu Jin called the Steam Engine Research Institute.

Jingcheng Machinery Factory is not very profitable at present, and now it is selling some textile machines and looms, but this thing, everyone will soon be able to study and imitate it, and everyone has stopped buying Jingcheng Machinery Factory.

Although the textile machines and looms of the Beijing Machinery Factory are of good quality and have few accidents, the price is indeed too expensive, and there have been many factories and workshops specializing in the manufacture of textile machines and looms in the Beijing-Tianjin area.

Springs and bearings are the most important money-making products of the machinery factory, these two things, high technical content, small factories, workshops can not be made at all, and these two things are all kinds of machines on the indispensable things.

But just relying on these two things, there is no way to feed such a huge machinery factory and so many craftsmen, so most of the time Liu Jin is still needed to subsidize it.

Liu Jin is a businessman, naturally will not always do loss-making business, Liu Jin has always been making people focus on the study of steam engines, as long as this thing comes out, it will inevitably set off a new steam revolution, driving the advent of the mechanization era, at that time, making money is trivial.

Steam Engine Research Institute, with the arrival of Liu Jin and Zhu Houzhao, Ren Siheng, the person in charge of the Steam Engine Research Institute, hurriedly brought people over.

"His Royal Highness the Prince, Childe~"

Seeing that Zhu Houzhao was also there, Ren Siheng also hurriedly saluted, he was very young, not even twenty years old, he used to be a blacksmith, and later entered the industry under Liu Jin.

Because people love to learn and are good at research, they slowly became the head of the steam engine research institute, responsible for the research of steam engines.

Of course, the steam engine is very simple, it is nothing more than the use of water vapor as power, but it is not easy to really delve into it and study a powerful steam engine.

If the steam engine cannot be sealed, once the air leaks, the steam engine will have no effect, and the power will be greatly reduced.

"Ren Siheng, how is the research on the steam engine?"

Liu Jin looked at Ren Siheng and asked with a smile.

"If you go back to Gongzi, the steam engine has already been studied, but we have been trying to find ways to continuously improve the power and stability of the steam engine."

Ren Siheng hurriedly replied respectfully.

For Liu Jin, he was full of infinite gratitude.

A few years ago, there was a famine in Beizhili, he was emaciated, hungry and cold, and fled to the capital with his younger brothers and sisters, seeing that he was about to starve to death and freeze to death, it was Liu Jin who took them in and let them enter the Xishan coal industry, which is what they are now.

was entrusted by Liu Jin with the important task of researching the steam engine, and he did not dare to slack off in the slightest, and studied it every day, devoting himself to the study of the steam engine.

Of course, he himself is also very fond of mechanical things like Zhu Houzhao, and thinks that the rotation between the gears is more charming than that of the eighteenth girl.

Liu Jin also gave him enough salary to make him worry about food and clothing, not only did he buy a house here in the capital and become a family, but even his younger brothers and sisters were sent to private schools to study.

"yes, let's go, take us to see~"

When Liu Jin heard this, he immediately laughed happily.

"His Royal Highness the Prince, Childe, please come here~"

Ren Siheng took Liu Jin and Zhu Houzhao to an empty room here, the whole room was placed with all kinds of machine parts, there was a steam engine in the middle, and there were many blackboards next to it, there were many things written and painted on it, and many people were carefully studying around this machine.

"This is the steam engine?"

Zhu Hou took care of the steam engine in the middle, and immediately became interested, and hurriedly walked over to take a look.

Recently, he has been obsessed with studying machinery, and when he saw the structure of the steam engine, he was in good spirits.

Liu Jin did the same, walked over and took a closer look at the steam engine in front of him.

Similar to the steam engine in my mind, a large boiler can burn coal and firewood underneath to heat the water in the boiler.

When the water is boiled, water vapor is formed, which enters a small piston and pushes the piston to rotate, and the piston is connected to the parts that need power.

It seems like something very simple, but Ren Siheng and they have been studying it for several years.

"This is the steam engine?"

"How does it work?"

Zhu Houzhao looked around this steam engine left and right, and didn't seem to think that it was anything special, as if it was not as good as the wheat harvester he had designed.

"Back to Your Highness, the steam engine, the steam engine, as the name suggests, is a machine that uses steam to propel the piston to generate power."

"There's a big boiler here, it's filled with water, and there's a fire burning under the boiler, and when the water is boiled, it produces steam, and when the steam enters the piston, it pushes the piston to rotate, and then it generates power."

Ren Siheng hurriedly began to introduce Zhu Houzhao in detail, the principle is very simple, and he can understand it as soon as he speaks.

"Listen to what you say, I understand, but if this steam wants to push the piston, the tightness should be very high, otherwise this air leak will not have any strength?"

Zhu Houzhao listened carefully, and said after thinking about it.

He studied machinery, and he was quite talented, and when he heard it, he knew that the core of this steam engine was tightness.

"Your Highness is powerful, you can see the difficulty at a glance."

"The principle of the steam engine is very simple, but it is quite difficult to manufacture, for this sealing, we have been experimenting for several years, coming up with many methods, and using a lot of materials."

"It wasn't until last year, from the Golden Continent, that Childe asked people to bring back a rubber thing, and our sealing was finally satisfactory."

"In addition, we cooperated with Miyun Iron Works, and after more than a year of research, we have developed seamless cylinder tubes, and the power of the steam engine has been greatly increased, and it has now become practical."

"Now the most important thing is the safety aspect, because our sealing is too good, the power is very sufficient, but it also leads to a very easy fryer, and we haven't solved this problem yet."

Ren Siheng nodded solemnly, His Royal Highness the Crown Prince is very powerful, and he can see the problem at a glance.

"Fryer?"

"If it's a fryer, why don't you design an air valve?"

"Once there is too much steam in the pot, this valve can automatically discharge the excess steam, so that it can be safe?"

Hearing Ren Siheng's words, Zhu Houzhao touched his chin, thought about it and said.

"That's right~"

When Ren Siheng heard this, he couldn't help but slap his face.

"Why didn't I think of this method, if there is an air valve, not only can it discharge some gas, to ensure safety, in fact, it can also be easily controlled, increase stability and control."

"Let's quickly redesign and add an air valve~"

Thinking of this, Ren Siheng also immediately got busy, and immediately began to redesign the boiler with his subordinates and add a gas valve.

"I don't think we should study something that can calculate the steam pressure in the boiler, so that we can accurately know the pressure in the boiler and make it easy to control."

Zhu Houzhao touched his chin, thought about it and added.

"Yes, yes, Your Highness, you are really a genius, too powerful~"

Ren Siheng nodded again and again, and immediately felt that he had met a confidant.

I have been studying the steam engine for so long, and I have always felt that it is not perfect, but now after what Zhu Houzhao said, I suddenly felt that it was suddenly enlightened, and I suddenly saw the appearance of a perfect steam engine.

As for Zhu Houzhao, hearing Ren Siheng's praise, the whole person was even more happy, a young man of this age is the age when he needs to be recognized the most.

His father and emperor naturally couldn't praise him for studying these things, and even felt that he was not doing his job, and he should learn the way of the king and learn the way of governing the country, instead of making these playthings and losing his mind.

As for his teacher Yang Tinghe, it is even more impossible to praise him, Yang Tinghe is already half angry and half dead, and he has not gone to class for a day in ten days, which makes him a teacher who has no face, and has asked Emperor Hongzhi for resignation many times.

Now just made two suggestions, Ren Siheng praised again and again, which made him even happier, and quickly mixed with Ren Siheng and them, and began to discuss how to better improve the power of the steam engine, improve the stability and control of the steam engine.

Liu Jin on the side was dumbfounded.

"Could this Zhu Houzhao also have crossed over?"

"How does he know about the gas valve?"

"How the hell does his head grow, it's too powerful, isn't it?"

Liu Jin really had to wonder if Zhu Houzhao was a traverser, as soon as he saw the steam engine, he knew about the gas valve, and he also knew that he had to develop an instrument to measure the water vapor pressure in the boiler, which was too demonic.

Originally, after listening to Ren Siheng's words, Liu Jin wanted to give Ren Siheng a little mention and talk about the gas valve and pressure gauge, but Zhu Houzhao actually thought of it first.

The key is that Zhu Houzhao is a person of this era, and he can think of this thing at once, which really makes Liu Jin feel incredible.

"Are the people of the future really wiser than the ancients?"

"Or is there really a genius in this world?"

"This Zhu Houzhao, what is his head made of?"
