This carriage really impressed me!

At the same time, it also shows a problem, many times I think it is too complicated, I always look at the problem from the perspective of the future life, and I hope that everything will be done in one step!

For example, this carriage, I thought that the four-wheeled carriage must use the steering machine to control the steering, but I didn't understand a truth: the development of things is from simple to complex, and maybe sometimes things that are not so advanced are the most suitable for the moment!

Yu Jin was also overjoyed when he heard my praise, this was the first time that Jiang Zuofu had made something without my guidance, and he was naturally overjoyed to be recognized by me.

"Your Majesty, this is what a minister should do!"

I nodded with satisfaction: "It seems that the establishment of this research institute is still useful, just continue to develop according to this momentum, and when I am gone, Daqin will still be able to develop rapidly, far ahead of the world!" ”

Yu Jin hurriedly said: "Your Majesty ten thousand years!" What a statement! ”

Yu Jin gave me an unexpected surprise, I was in a good mood, and said with a smile: "You can do the four-wheeled carriage yourself, tell Sima Li, someone will buy it!" ”

"Yes!"

I looked up and said with a little anticipation, "Alright, let's turn on your main event." ”

Yu Jin waved his hand: "Lift the oil paper cloth!" ”

Immediately, four strong men stepped forward to untie the ropes, and as the oiled paper cloth was lifted, a large, but rather delicate-looking machine appeared before me.

My eyes lit up, and I immediately stepped on the back of the carriage and got into the carriage, and Yu Jin and others hurriedly escorted me below.

This machine appeared in the Qin Dynasty BC in the Qin Dynasty with an unreal feeling, saying that it was huge and only relative to the steam engine under the industrial system, compared to the four dissimilarities made last time, this thing can be called small and exquisite.

I took a closer look and found that the flywheels, crankshafts, connecting rods, cylinders, etc., were all connected, and the pistons were made of rubber from the rubber mill!

I watched for a quarter of an hour before I got out of the carriage, and Yu Jin was looking at me a little nervously below, for fear that I would be the last evaluation again......

I stepped forward and patted Yu Jin on the shoulder, and said solemnly: "Yes, good!" ”

Yu Jin was suddenly overjoyed, and the corners of his mouth could barely be suppressed: "Your Majesty, the minister immediately ordered someone to load coal and see if he could move?" ”

"Uh......" I was surprised, "why do you want to load coal?" ”

Yu Jin was stunned for a moment: "Didn't Your Majesty say that the steam engine is powered by coal?" ”

I patted my forehead, knowing that he had misunderstood what I meant, and smiled helplessly, "I just said that the steam engine was very good this time, but I didn't say that it could run." ”

Yu Jin was a little confused: "This ......"

I clapped my hands, turned around and walked towards the inner hall: "Let someone carry it into the room, I will tell you in detail, and you can continue to develop this steam engine in the future." ”

Although Yu Jin was a little puzzled, he still ordered someone to carry the big guy into the house.

In the middle of the hall, I sat on a chair and pointed to the steam engine and said, "Although this machine has begun to take shape as a steam engine, it still can't run, and if it doesn't run, it's the best result, and if you don't pay attention to it, it will explode!" ”

Yu Jin was a little puzzled: "The minister designed the pressure relief valve according to the drawings." ”

I shook my head: "The two most important parts of a steam engine are the cylinder and the piston. ”

This machine is not covered with a lid, you can see most of the parts intuitively, I pointed to the cylinder and said: "First, to ensure the constant temperature of the cylinder, so that the cylinder will not explode because of excessive pressure or high temperature, the pressure relief valve you said is an emergency device when the cylinder can not maintain a constant temperature normally, but the cylinder must ensure a constant temperature during normal use." ”

"That's why this condenser tube is needed to separate the condensation process of steam from the cylinder, which can accelerate the cooling of steam and greatly improve the heat conversion efficiency. But if you look at your condenser tube, how can it withstand the pressure of steam at this level of tightness? ”

Then I pulled out the piston again: "The same problem, although your piston is made of rubber, you can see at a glance that this is the rubber you use on the tire, and the wear resistance and tightness are far from meeting the requirements!" What's the problem? It's the process of making rubber, there must be a problem with the vulcanization time, and I didn't strictly follow the process specifications I gave you! ”

Yu Jin nodded thoughtfully, his eyes staring at the piston, as if thinking about what was wrong.

I put down the piston in my hand: "This is up to you to find out what the problem is, remember, industry is an industry that pays great attention to procedures and norms, and any little error will lead to scrapping of equipment, and it will hurt people's lives!" ”

Yu Jin's face was solemn, and he arched his hand and said: "Thank you for Your Majesty's teachings, keep in mind!" ”

I smiled and relaxed: "There are some other problems, such as ...... here"

The problems existing in the steam engine were pointed out one by one in detail, and Yu Jin had already come to the paper notebook, full of five pieces of paper!

An hour later, I stretched and smiled, "Still, this machine of yours is epoch-making!" If this momentum continues, there will be ten or eight years, and a steam engine will definitely be built! ”

Yu Jin's face was bitter: "Ten years and eight years? ”

I laughed and said, "That's optimistic, don't think it's close, I'll tell you the truth, it's not too early for you to build a steam engine that can work!" Ten or eight years is the most optimistic situation! ”

Yu Jin nodded, and sighed helplessly: "It's not easy!" ”

I got up and looked at the house full of things, and basically all the things after moving the house over, such as the curved plow, keel waterwheel, all kinds of farm tools, textile machines, etc., looking at these things that did not belong to this era were piled up in a room, I was also infinitely emotional!

It's been twelve years, and it's really not easy for me to be the emperor!

People can really die of exhaustion!

Fortunately, there are various learning palaces and new research institutes, and when these talents grow up, I don't have to worry so much, and I will have to bow down to everything.

Seeing that Yu Jin was still immersed in the steam engine, I reminded: "What about the model of the Daifuku ship?" ”

With the steam engine Zhuyu in front of me, my confidence in the Daifuku ship has also increased a lot.

However, when I thought of the ten warships that had disappeared on Qindong Island, my heart was clouded with another layer of haze.

Where the hell did they go? Is it a disappearance or a defection?

Yu Jin's voice pulled my thoughts back: "Back to Your Majesty, in the back garden pool, it's relatively big, and it can't fit in the yard." ”

I nodded, the models made in this era are extremely delicate and detailed, such as the model of the Lishan Mausoleum, which is almost the size of three houses!

"Let's go check it out, I'm looking forward to it."
