Douluo: My dear grandson, come quickly, Grandpa, I am Titled Douluo

Chapter 221 The steam engine has become
Hu Yanxiang led the law enforcement team and set off from Jiancheng mightily.

This ancient military fortress fell into peace again.

The streets are empty.

Only the military factory on the street in the backyard of the Dutong Mansion was still tinkling non-stop.

"My lord, the steam engine is ready!"

Dutong Mansion, Study Room.

Ye Tian is writing the current military information for Wuhun City.

Amaury, with a gray beard, came laughing.

Even disregarding the etiquette, he pushed the door open and walked in.

"It's done!" Amory's face showed joy.

"Just now, the old man ordered someone to try it. The power generated by the steam engine can easily equal [-] horses!"

"Oh!" Ye Tian put down his pen and raised his eyebrows.

This was a pleasant surprise.

Having a steam engine prototype means that more steam engines will be manufactured.

Douluo already has the ability to enter the steam age.

"Su Ziwen is still in the process of debugging. Please, Mr. Dutong, go and have a look." Amori stretched out his hand and asked.

"It's time to take a look."

Ye Tian stood up from his seat, pushed away the chair, walked to the middle of the study, stretched his waist, and exercised his muscles and bones.

Only then did he push open the study door, and together with Amory, walked towards the small door in the backyard.

Su Ziwen's speed of developing the steam engine was somewhat beyond Ye Tian's expectation.

The drawings he asked Su Zi were still very simple.

It's not the manufacturing blueprint of the steam engine, it's just the principle.

As we all know, there is actually a long way to go for technical principles to be separated from real engineering applications.

In order for Su Ziwen to devote himself to the study of steam engines.

Ye Tian specially asked Su Zi to open up an independent courtyard.

After entering the courtyard.

I saw that the courtyard was filled with all kinds of gears and small parts.

More than a dozen craftsmen are discussing in a hurry around a roaring machine that emits black smoke.

"The workpiece is not qualified at all, and the steam is leaking out!" A low-faced, fierce-looking craftsman with bloodshot eyes shouted.

"Gong Liang, you're being a bit picky. This piston, after eight days of grinding, is absolutely round." The thin craftsman assured, patting his chest.

"What I want is the result, don't tell me the working hours! Your monthly salary is gone!" the low craftsman said angrily.

"Mr. Su's grinding is not qualified!" The emaciated craftsman was very angry, and rolled up his sleeves, as if he wanted to fight.

"Master Dutong is here." Amory, who was behind Ye Tian, ​​shouted.

All the artisans who were talking about it turned around.

They all stepped forward to worship Ye Tian.

Among the crowd of craftsmen, Su Ziwen, who was staring at the steam engine and thinking, also shook his head at this moment, stepped forward, and saluted Ye Tian.

"My lord."

Ye Tian nodded.

With hands behind their backs, they came to the rumbling steam engine.

Looking at the first giant steel beast in Douluo World.

Thanks to the support of many artisans.

Su Ziwen is also the apprentice of the master craftsman Lou Gao. In terms of forging skills, it can already be said that he is the top group on the mainland.

Therefore, the steam engine in front of me has been miniaturized.

The lower part of the steam engine is a blazing stove, and above the stove is an inverted 'concave' water tank.

There are two more copper pipes in the water tank, connecting the two steam cylinders.Two steam cylinders pushed a large round wheel that rotated rapidly.

It can be said that the essence of the steam engine has been demonstrated on this prototype.

"That's right, if you install four hubs and a valve on the delivery port of the steam engine, this thing can drive the train to run across the field."

Su Zi who heard the words asked, with a wry smile on his face.

"My lord, it will probably take a few months for your wish to come true."

"We have encountered a big problem now. The steam engine has only been running for less than an hour, and it is already on the verge of damage."

Hearing this, Ye Tian showed doubts.

Immediately, I thought of the conversation of several craftsmen when I entered the courtyard.

He walked up to the cylinder, and sure enough, he found the problem.

When the steam engine is running, most of the steam escapes into the air through the gap.

There is no motivation to be a steam engine at all.

Although the furnace below is filled with coal mines, the fire is burning very vigorously.

Steam is also continuously generated.

But the steam engine in front of him can generate less than two horsepower, Ye Tian estimated.

Su Ziwen sighed and said:
"With your support, my lord, the material used to make the power cylinder of the steam engine is already the best steel in our place."

"It was all transported from the blast furnace in Soto City, and then re-forged by the blacksmiths. This kind of steel is more than enough to make fine steel weapons."

"Unfortunately, the cylinder is worn out badly. In the first 10 minutes, it worked normally."

"After 10 minutes, the cylinder was scratched. The craftsmen and I have changed three cylinders, and this happens all the time."

Speaking of this, all the craftsmen present were all frustrated.

Amory, who was beside Ye Tian, ​​scratched his head in embarrassment:

"I'm really sorry, Mr. Dutong. I didn't expect such a problem with the steam machine when I went out for two hours. It makes you happy for nothing."

"Since there is a problem, let's solve it together. President Amaury, don't forget that my blacksmithing skills are no worse than anyone else here."

"Stop the machine first." Ye Tian beckoned, and what Su Zi asked was a tricky question.

Douluo's steel industry is too backward after all.

"Yes." Amaury hurried forward and waved.

Several blacksmiths understood immediately.

This prototype steam engine has nothing yet, a brake and flameout device.

A blacksmith used the most primitive method, directly holding a basin of water to extinguish the coal fire in the stove.

Another blacksmith took out a large iron crowbar and pried open the water injection port of the steam engine.

Stab Lala!
White steam quickly emerged from the water injection port.

The roar of steam stopped abruptly with this sound.

Su Zi asked and thought:

"My lord, I suspect that this steel material is not enough to support the power of the steam engine. Can I apply for some Mithril alloy?"

Hearing this, Ye Tian smiled and shook his head: "Steel materials are enough to make steam engines, it's not a matter of materials."

"Mithril alloy is too expensive. Even if it is manufactured, there is no problem with the steam engine, and it cannot be promoted on a large scale."

Ye Tian stepped forward and took the cylinder off the machine very skillfully.

With just a glance at it, Ye Tian understood instantly.

"It turned out that it was just a problem of pulling cylinders."

Whether it is an internal combustion engine or a steam engine, oil is needed as a lubricant.

Without lubricant, after a few minutes of operation, the friction will increase due to thermal expansion and contraction, which will damage the precision parts.

"Get a bucket of animal oil in the kitchen." Ye Tian said to Amory.

In a world with low productivity like Douluo, engine oil is out of the question, but animal oil can do just fine and can act as a lubricant.
