Great Tang princess

Chapter 814 Internal Combustion Engine Experiment

The next day, Li Yuechen went to the engineering institute as soon as he finished practicing, and asked about the specific matters of the glass mirror.

According to the answers of the craftsmen, the production process of this glass mirror is quite mature.

The production is also relatively stable, and now there are nearly 100 yuan in the warehouse of the Engineering Institute.

Judging from the more than 100 test products, the scrap rate is not high.

The only problem is the cost.

After all, silver is used, and Datang's current silver output is not high, so the current price of silver is not much lower than the price of gold.

If it is roughly converted according to purchasing power, the current price of silver is equivalent to 150 yuan in the future.

Then replace it with the banknotes used in Datang today, an octavo-sized mirror, and the cost is about [-] cents.

In that case... just set the price at 300 yuan!As for the unsatisfied with this size, you can also order it at a high price!

The [-]-carat price is [-], and the smaller one is [-].

Fifty is the lowest, and if it is smaller, it will not be sold.

After all, folks don't need this stuff nowadays, so let's harvest a wave first.

The price can be lowered slowly, and it would be nice to lower it to the price of cabbage after ten years.

So Li Yuechen nodded: "You guys sort out the production methods, and I will open a mirror factory after I go back."

Pei Bishu quickly agreed. Although the process was somewhat difficult, once it was done, it naturally felt a lot easier.

And I have to say that the clarity of this mirror is really high, even the moles on my face can be seen clearly.

"Your Highness, the experimental product in the warehouse..." Pei Bishu opened his mouth a little shyly.

Of course, Li Yuechen also knew what he wanted to do, so he smiled immediately: "You don't need to take those, when the time comes, everyone in the Engineering Academy will send one to everyone they want, and it will be considered a welfare."

Anyway, the cost of this thing is not high, and each person can send one side.

As for whether they will use it at home or sell it, then let them go, and I don't bother to care about it.

"My subordinate would like to thank Your Highness here first!" Pei Bishu hurriedly saluted.

"Okay, speaking of it, it's already August now, remember to make a big mirror that can reflect your whole body, so that you can give it to the saint during the Chinese New Year." Li Yuechen reminded.

Pei Bishu nodded: "Don't worry, Your Highness, after the experiment is successful, the subordinates are already making preparations. However, the mirror itself is simple, but it will take some time to make the frame..."

"Ah, it's all right. There are still a few months, should it be enough?"

"That's natural, please rest assured, Your Highness!" Pei Bishu quickly assured.

After confirming the matter about the mirror, Li Yuechen nodded and prepared to leave.

However, Pei Bishu suddenly stopped her: "Your Highness, the internal combustion engine will be tested in a few days. I don't know much about it, but it's better for Your Highness to come and see it in person."

"Oh? That's good news!" Li Yuechen nodded, "It's easy to say, when the time comes, Ben Gong will come over in person!"

……

It is indeed good news that the internal combustion engine will be tested soon, and Li Yuechen had a smile on his face when he returned.

Even in the next few days, I felt a lot better every day, and I was looking forward to sending someone from the Engineering Academy to inform her.

Three days later, Li Yuechen received a letter from his mother in Qingdao.

In the letter, he was full of praise for the mirror that was delivered a few days ago, and praised her well.

Then she said that it was almost September and the weather in Qingdao was getting colder, so she planned to leave for Zhenzhou.

The difference is that instead of taking the airship this time, we will go by boat.

After all, there are too many people, and if you take a boat, you can experience the customs and customs of various coastal cities along the way.

Li Yuechen agrees with this idea. After all, there are not many airships, and it would be better to take a boat.

Anyway, Liu Zihe and the others set off after the Chinese New Year, so they didn't feel too nervous about using a boat during this time, and a big boat would be enough to send her to Hainan.

There are no pirates in this era, and there are artillery on board, so there is no need to worry about safety.

Li Yuechen wrote back to his mother, asking her to play as she pleases, as she pleases, without worrying about things here.

By the way, it will be August [-]th, so I gave my mother a blessing in advance.

I won't go to spend time with her this year... I believe she will understand.

……

On August [-]th, Li Yuechen got up early. After practicing yoga, he did not continue to practice, but put on Taoist robes to chant scriptures.

Over the years, this habit has never changed. The 15th of every month is a day for chanting.

After finishing reading, it was almost noon. After having lunch and resting for a while, I immediately set off for the Engineering Academy.

Today is the day of the internal combustion engine test. Under the high expectations, this thing is finally made.

On the way to the Engineering Academy, Li Yuechen couldn't help thinking that if the experiment was successful, it might be able to explode into many different uses at once.

For example, cars and trains that are already under research, these two alone can greatly change the current life.

Seeing her smiling happily, Yiluoru couldn't help asking: "Your Highness, is the internal combustion engine really so magical?"

"It's somewhat troublesome to explain. If you haven't retired by then, you might be able to see it for yourself." Li Yuechen smiled.

Since the last time I said to let some guards retire, Li Yuechen's guard team has lost a lot of people.

After all, they are of marriageable age, and about half of them chose to retire.

As for Li Yuechen's arrangements for them, there are two choices.

The first is to receive 3000 yuan in retirement fees and arrange jobs and accommodation for them.

The second is to only arrange accommodation and not work, but you can receive a one-time discharge fee of 8000 yuan.

Of course, no matter which one you choose, this so-called accommodation arrangement is not a direct delivery of a house.

The residence arranged for them cannot be rented out, they can only live by themselves, and the land deed will be given to them after they have lived there for 20 years.

After all, this is also a means of supervision.

After all, he used to be the princess's guard and knew a lot about the princess, so the follow-up arrangements must be made well.

The house assigned to each person is not small, basically a single family with a small courtyard.

The combined area of ​​the house and the area of ​​the small courtyard is almost [-] square meters.

The only problem is that the location may not be very good, they are all on the southeast corner.

After all, there are only a few people in the Eastern Capital, which can build a large number of houses.

These guards live here, and most of them will be neighbors in the future, and they will take care of each other.

……

All the way to the Engineering Institute, just arrived at the door, and saw a group of craftsmen waiting here.

As a large project that took many years, these craftsmen worked hard and overcame various difficulties, and finally made the real thing!

Pei Bishu trotted all the way over: "I've seen Your Highness!"

"No!" Li Yuechen jumped off the horse neatly.

The craftsmen who greeted him at the door also saluted, and Li Yuechen kept walking in: "It's all free, go in and have a look!"

The craftsmen agreed and followed her into the laboratory.

As soon as he entered the door, Li Yuechen saw the engine on the shelf in front.

The whole body is silvery white, exuding a sense of industrial beauty, exuding a light that does not belong to this era.

This is a four-cylinder engine, not too big, just like a stool.

But the grotesque appearance is enough to catch anyone's attention.

At this time, there was no need to say any more nonsense, Wang Gangdan walked over with a porcelain bucket in his arms.

After Li Yuechen nodded, he asked his apprentice to open the lid of the fuel tank, and poured the barrel of gasoline into it himself.

After filling it up, he screwed the lid on, turned his head and said, "Your Highness, the preparations are complete."

"Ok!"

After agreeing, Li Yuechen took a step forward: "Okay, everyone back up a bit, in case it explodes..."

"Don't worry, Your Highness, this subordinate is sure and will never blow up!" Wang Gangdan replied.

Things like internal combustion engines have exploded many times during the experiment. If he is not absolutely sure, he would never dare to let the princess do it herself.

Seeing his confident face, Li Yuechen smiled: "That's good!"

Then put your hand on the ring.

That's right, Griph.

After all, Li Yuechen really didn't know what to do with the battery, he had no clue at all.

So even if the engine is made, the electric ignition system cannot be made.

So the switch becomes a pull cord type.

It may sound a little behind, but this engine is definitely made according to the specifications she is most familiar with in the future, it is nothing more than a different starting method.

After grabbing the tab, pull it back.

The flywheel rotates quickly, followed by a "hum".

The machinery that surpassed the age made its first roar, announcing the arrival of a new era.

Seeing the engine starting to run and the piston jumping up and down in front of them, everyone's eyes widened and they froze in place.

For the ancients, this is an unimaginable picture.

A machine can actually move by itself without relying on any external force.

Even for these craftsmen who have already achieved the top level in the country, this is still a very ruinous picture.

All the people present stared blankly at the engine that continuously emitted not-so-rich smoke from the iron pipe.

Li Yuechen, who was standing at the front, was stunned for a few seconds, then suddenly grinned, opened his arms and shouted: "Woohoo——"

This loud shout pulled everyone back from the shock, and then burst into cheers!
Pei Bishu couldn't help but raised his hand and patted Wang Gangdan's shoulder: "Hahahaha...it's really done! Amazing! Hahaha..."

Wang Gangdan also kept nodding: "I can make such a fetish in this life, I will have no regrets in this life!"

"Hey, don't say such ominous words! This is a fetish of design..." Pei Bishu couldn't stop laughing.

The others were also talking loudly to each other's colleagues. Judging from their expressions, they were all very excited at this moment.

Those who are here now are all direct participants in this project.

If it wasn't for the success of what the princess proposed before, they wouldn't even dare to believe that this thing is real.

However, when I saw the engine actually running, I was still surprised and excited even though I was mentally prepared in advance.

The surprise lies in the unexpected success of this thing, and the excitement is because with the existence of this thing, cars and trains in the future can really go from imagination to reality.

At the same time, many people gathered in the open space outside the laboratory.

When they heard the chaotic cheers coming from inside, they all guessed what happened for a while.

……

In the laboratory, everyone's excitement gradually calmed down.

Looking at the engine that was still running smoothly and roaring in a low voice, although the emotions were still agitated, at least they were no longer cheering as loudly as before.

Li Yueche took a deep breath, then reached out to close it.

After the roar of the engine stopped, she turned around, looked at the craftsmen behind, and nodded with a smile: "This internal combustion engine has been successfully developed, and all of you present here have contributed a lot! It deserves a collective special merit!"

After everyone heard this, they saluted one after another, and then thanked everyone in a hurry.

Then Li Yuechen turned his head, looked at Wang Gangdan and said: "This thing can be successfully developed, you are indispensable!"

"The subordinates dare not, as His Highness just said, there is only one subordinate, otherwise we can't..."

"Okay, humility is off the table." Li Yuechen smiled, "Although it has been successfully developed, there is still a long way to go before it can be put on cars and trains. Next, there is still work to do! "

Wang Gangdan nodded: "Your Highness, don't worry, the first step is done, and the follow-up will be relatively simple. I will study it now!"

"Well. This matter cannot be made public for the time being. When the trains and cars are put into use, your achievements will surely be spread all over the world!" Li Yuechen nodded and said.

The gold content of these words is not ordinary, and Pei Bishu next to him showed a look of envy.

This is definitely going to be left in history, and it is simply an unimaginable glory for ordinary people.

However, Wang Gangdan is an illiterate craftsman and has no such pursuit.

So after hearing it, I just saluted and thanked him very respectfully, and didn't have an overly excited expression.

Li Yuechen also knew that for such an old craftsman, it would be better to reward something real.

So he immediately announced that this month's bonus would add 1000 yuan to him!
For today's economic level, this reward can be said to be unimaginably high.

And it's not just him, all the participants in this project have different levels of bonuses.

Now Wang Gangdan's expression finally became excited, and he saluted repeatedly to thank him.

Li Yuechen waved his hand: "Next, in addition to the train and car engines, I will make another small one. I will send the design drawings in a few days."

"Why is your Highness still younger?" Pei Bishu was puzzled by this.

"For weeding!" Li Yuechen said, then turned and left.

After all, it is decided to build a golf course, and the lawn needs to be dealt with.Therefore, a lawn mower is needed to make the grassland the same height.

If this work is done by hand, it is too time-consuming.

It just so happened that the internal combustion engine was successfully developed today, so let’s make a small one and get a lawn mower first.

Not only can it be used on the court, but the most critical issue is that a large number of mechanical farm tools will be manufactured in the future to improve the country's production level!
