Just when the entire Great Qin was working hard to establish an official school, good news also came from the steam engine factory.

Huang Yuan and Ying Heng led a group of craftsmen to point out a little excitedly in the internal combustion engine research and development workshop of the steam engine factory, facing a machine that had just been assembled!

"Heng Gongzi, Huang Shaojian, the internal combustion engine has been successfully assembled!"

After more than two years of research day and night, all the parts of the internal combustion engine have finally been built.

For the sake of this small internal combustion engine, I don't know how many craftsmen have bothered their hair!

"It's finally successful, it's not easy!"

Since Ying Heng began to study electricity with Huang Yuan, he has become more and more interested in scientific manufacturing.

Up to now, the palace has almost no trace of him, and he has followed Huang Yuan to study and inspect various factories during the day.

Only at night do I go back to the palace to sleep!

I even hope to get married as soon as possible, just like Fusu, living outside the palace in a bright and bright way!

"Let's start testing!"

At this time, Huang Yuan, in addition to being excited, was more worried.

Although everything is made according to the drawings, he can't guarantee whether it will work normally, and he can only know if he has tested it!

"The imperial brother has been looking forward to this internal combustion engine for a long time, if it can be used normally, the imperial brother will be happy!"

Ying Heng squinted his eyes and stared at the internal combustion engine tightly.

He firmly remembered that the emperor's brother had said that although it was difficult to manufacture the internal combustion engine, as long as it was built well, it would push Daqin to take a big step forward!

It is even said that in the future, the application of internal combustion engines will be more extensive than steam tractors!

Trains, cars, tractors, all can be converted into internal combustion engines!

"Come on, pour oil!"

For this day, Ying Feiyu has built oil refineries across the country to produce gasoline and diesel without interruption.

In this way, when the internal combustion engine is successfully developed, there is no need to worry about running out of oil!

"Fire!"

After the diesel fuel was slowly poured into the fuel tank of the internal combustion engine, Huang Yuan ordered again.

With excitement, the craftsmen set the internal combustion engine in motion!

"Boom ......"

As a puff of smoke came out, the internal combustion engine really turned and roared.

"Succeeded? Did we really succeed? ”

A few craftsmen pouring oil and lighting the fire seemed to be in disbelief, and froze in place excitedly.

"Great, after more than two years, this internal combustion engine has finally been built!"

Ying Heng has been with Huang Yuan for a long time, and he knows how much effort he has put into this internal combustion engine.

Now that the manufacturing is successful, he is also happy!

"Just being able to operate is not a real manufacturing success! You have to look at the motivation! ”

What the internal combustion engine later needed to replace was the steam engine.

If the power is not good, it is equivalent to manufacturing failure!

"Hmmm! Again, can such a small machine really replace a steam engine? ”

Ying Heng had a hint of suspicion.

You know, the size of the steam engine is not small!

Even the kind that has been improved and can be installed in a steam car is several times larger than the internal combustion engine in front of you!

"Try it and you'll know!"

In the two years of internal combustion engine manufacturing, Huang Yuan also came up with a complete set of test methods, and waited for the internal combustion engine to be successfully manufactured and tested.

Everyone waited for the installation of the craftsman, that is, a moment of effort, and then began the test!

This test is just to see how powerful the internal combustion engine is!

"Boom ......"

With the roar of the internal combustion engine, the joy on everyone's faces was even greater.

"Not bad!"

At this time, Huang Yuan really showed a smile on his face.

"It's not bad, the power of this internal combustion engine has surpassed that of a steam engine! I really didn't expect this small machine to have such power! ”

The winning balance was also quite pleasantly surprised.

"The steam engine needs to add water and firewood, and there must be space to store steam, so it is relatively large! This internal combustion engine is not so troublesome! Otherwise, His Royal Highness the Crown Prince would not have spent so much manpower and financial resources to produce this internal combustion engine! ”

Huang Yuan said with a smile.

"Quick! Go and inform your father and brother and let them come and have a look! ”

Ying Heng hurriedly beckoned the craftsmen around him to run errands.

"Yes!"

The craftsmen answered with joy on their faces and immediately ran out.

The internal combustion engine is a project, and if you build it, Your Majesty and His Royal Highness the Crown Prince will definitely be rewarded!

……

Due to the compilation of teaching materials, Ying Feiyu almost did not leave the palace during this time, and the craftsman arrived at the palace and conveyed the good news to the two.

After the two learned about it, they didn't stay for a moment, and immediately followed the craftsman to the R&D workshop of the steam engine factory!

"Hahaha! Is the internal combustion engine really studied? ”

As soon as Ying Zheng entered the door, he laughed heartily.

"Back to Your Majesty, it has indeed been successfully developed!"

Huang Yuan took a group of craftsmen, walked a few steps quickly, and went to greet him.

"Great! That's great! ”

Hearing this affirmative answer, the joy in Ying Zheng's heart was indescribable.

"Your Majesty, this is the internal combustion engine!"

led Yingzheng and his party to the internal combustion engine and made a gesture of please.

Ying Zheng is the first time to see an internal combustion engine, except for being happy, he can't see any way!

Ying Feiyu was different, staring at the internal combustion engine carefully, and after a while, he showed a pleased smile.

"Your Highness the Crown Prince, how's it going? Was it a success? ”

Even though he had already tested the power, Huang Yuan still had no bottom in his heart, and asked tentatively.

"It worked!"

Ying Feiyu nodded firmly.

"Hoo ......"

Huang Yuan breathed a long sigh of relief, "Please Your Majesty and His Royal Highness the Crown Prince watch its momentum!" ”

The craftsman showed it to Ying Zheng and others, and received a lot of applause from Ying Zheng.

"I remember that your kid once said that as long as the internal combustion engine is produced, Daqin's industry will be more prosperous?"

"That's right! Everything that my father knows now about the steam engine will be taken to the next level! ”

Ying Feiyu nodded firmly.

"Can cars and ships run faster? Can a loom weave more cloth? ”

"That's right!"

"Sizzle......"

Imagining the scene in the future, Ying Zheng couldn't help but gasp.

Today, a single loom is enough to fit dozens of female workers.

After the installation of the internal combustion engine, wouldn't it be worth hundreds of female workers?

"Isn't it possible to plough more land if it is installed on a tractor?"

Cultivated land is the foundation of the country, and it is also the issue that Ying Zheng is most concerned about.

Only when there is more food can more people be fed, and the people will have children with peace of mind and develop the population!

"Of course, the internal combustion engine is equivalent to the heart of the tractor, as long as this heart is full of power, it will naturally have energy to work!"

Ying Feiyu nodded.

"Good! Then mass produce the internal combustion engine, and replace all the tractors with the internal combustion engine, so that the people can plow more land and produce more grain at the time of spring ploughing, haha! ”

Ying Zheng smiled heartily, and his demonic laughter echoed throughout the workshop.
