Behind me is the entire history of mankind!

Chapter 75 Internal Combustion Engines (Two in One)

The update of the new version was gradually discovered by the players, and many players began to approach Da Vinci to apply for land.

But obviously, Da Vinci will not grant land to these people casually. Even if those who apply for ranch and cultivated land have no relevant experience, they must know some relevant knowledge. Otherwise, even if the land is approved, it will be a waste of the united front resource.

They have a lot of land, so the review is actually not strict. Now that the search tool is so easy to use, you can find relevant knowledge with a little Baidu.

"The eastern area will be planned as arable land, and we can rent out the ten acres of land to you. At the same time, we encourage the cultivation of two crops, potatoes and wheat.

From the base, you can receive the seeds of these two crops for free.

Do you know how to grow potatoes? "

"Of course, of course." In front of Da Vinci, a player named "Potato Tomato" nodded, "Potatoes are quite easy to grow, as long as the land is plowed, germinate first, then cut into pieces and bury them in the soil. It’s just fine, this season is just right for growing potatoes.”

Da Vinci nodded, and at the same time, a "cultivation" task appeared on his UI panel, as well as his arable land map and arable land electronic contract. He ran excitedly to the base, probably to the warehouse Get the potato seeds.

Da Vinci looked at Nan Sheng who was sitting at a small square table and was burying his head in front of a piece of white paper and drawing something with a pen.

The blank paper and pens are already in the base. The quality of these products of modern civilization is very good. Even after 1000 years, it still retains its original functions.

For those last batch of human beings, they need to stay in the dark base for the rest of their lives, which is a kind of great suffering and pain, so they need the satisfaction of the spiritual world.

The drawing boards, blank paper, and brushes that Lincheng gave to Da Vinci were all found in the base. Dr. Lin Nuo can also draw.

"How about the design of the waterwheel?" Da Vinci asked. "Your waterwheel can be of great help to such cultivators."

Nan Sheng raised his head to look at Da Vinci and said aggrievedly, "Teacher, I study painting, not water conservancy."

Leonardo da Vinci smiled, "The essence of painting is to express, to express one's emotions as well as to observe and understand the world.

In a sense, music also has the same essence, but unlike music, painting can express emotions through sound.

The way painting expresses emotions is through the interweaving of colors, which represent warm yellow, pure white, and passionate red.

And there is another emotional way is the details.

The details that people show when they express their emotions, such as the creases at the corners of the eyes when a person smiles, for example, when a person's arm is bent, an imperceptible muscle will appear on the arm.

Whether it's anger or joy, people's expressions will change accordingly. This change is very detailed and cannot be discovered without corresponding observation skills.

If you want to know these details, you need to rely on knowledge. If you want to design a waterwheel, you need to know the power of water, the velocity of flow, and the nature of water.

And this knowledge will eventually become the details revealed by the brush in your hand.

If you can understand how a bird flies, which muscles it uses when it flies, and what role the feathers play in it, you can make the bird "fly" in the painting.

At the same time, you can also make the "bird" fly in reality. "

Da Vinci smiled, raised his hand and touched the table in front of Nan Sheng, the brilliance of ether particles shone on his arm, and part of the table was broken down.

Then, under Nan Sheng's gaze, a delicate wooden pigeon appeared in front of her. The pigeon was very delicate and lifelike, and every feather pattern on it was carved out.

But just when Nan Sheng thought it was just an exquisite handicraft, the pigeon actually moved.

It spread its wings and strode its own bird feet, without any obstruction, very naturally, with the breeze blowing, the bird actually flapped its wings and rushed to the sky!
"Flying up!?" Nan Sheng exclaimed, she looked at Da Vinci incomprehensibly, "How did you do it? It's just wood, without any fuel or engine inside, it's just unbelievable."

"Knowledge." Da Vinci smiled, "Want to learn?"

Nan Sheng nodded like a chicken pecking at rice.

"Go and pick up that bird, you can take it apart and have a look, it's just some very simple structures."

"All of a sudden it became lively."

Da Vinci looked at Nan Sheng's leaving back, then looked at the voices rising and falling in the bastion and said with emotion.

"How's the result today? Da Vinci." Lincheng asked with a smile through their internal communication channel.

"It's okay, the auction house is almost finished. After the strategy post was posted, dozens of acres of cultivated land in the east have been contracted successively, but no one has contracted the pasture. These players seem to be more willing to farm than to herd. Some, I thought it would be the exact opposite," Da Vinci said.

"After all, it's something in DNA." Lincheng nodded and said, "Is there any qualification review?"

"After review, they are all people with relevant experience." Da Vinci said.

"According to the current trend, you should be able to eat without worrying about food from February to March next year." Lincheng laughed.

"Food is second. The key is to quickly enter industrialization and build an industrial chain. The best way is actually to go to the past and buy ready-made machines." Da Vinci said.

"Lovely Instein said."

"Our space-time model has been built." Einstein's voice sounded in their ears, "The arrival of Fermi has provided us with a lot of help in calculations, and the Nuwa system is also very useful."

"You are too much, Mr. Einstein, when I came, you had already completed 90.00%." ​​Fermi also said on the communication channel.

"Okay, listen, kid, the tree of time and space starts to branch from the time and space you are in in 2069, until 3069, when human civilization completely disappears and dissipates.

The human history before 2069 became the "root" of this time-space tree, which supported all the parallel time-spaces that were born in the past 1000 years, and this structure temporarily formed a certain stability.

Therefore, my suggestion is that we can only obtain materials in 2069, and try not to affect the rest of time and space after 2069 in order to maintain stability except for bringing people. "

"Fortunately, I didn't actually go to World War II to obtain supplies." Lincheng said.

"Spacetime has its own adjustment ability." Planck said, "It can adjust some small changes by itself, and it is still possible to bring some things that do not affect spacetime.

But no one can be sure about something like the butterfly effect. No one knows what kind of future a certain thing you take away will eventually lead to. "

"For example, if you took away a gun in World War II, which caused an important person to survive, and took away a few tanks, which led to a change in the outcome of a certain battle." Tesla said.

After a pause, Einstein continued to add, "Remember, when going to your time and space to buy necessities, it is best not to have too much at one time, after all, traveling through time and space consumes your energy, even if it can be replenished through food.

Secondly, even if we have the ability to bring things from the past, we should use it with caution. No one knows whether the thousands of years of human history can support the ever-increasing parallel time and space. "

"I know, that's enough!" Lincheng said excitedly, "Then just give these machines a reason to appear."

"Just say it was discovered from the Prometheus Base." Tesla said, "We currently need some punching machines, various machine tools, and production lines to reduce the application burden of ether particles. We can produce bullets first. .”

As he spoke, his words froze slightly, and in front of his eyes, Blitz Poland was pulling something like an engine and walking over.

"Mr. Tesla, I think we can automate cranes and mass-produce excavators."

As he said that, he poured a pot of oil in his hand into the opening of the engine, then grabbed a certain rope on the engine, and pulled it hard, the reaction engine trembled violently, and some black smoke came out of it. out.

"Internal combustion engine, what did you do?" Tesla looked at Strike Poland in surprise.

"I asked Wild God to use alchemy to make some parts for me." Blitz Poland laughed.

"Where did you get the material?" Tesla asked.

"The aluminum alloy used for the cylinder, I smelted aluminum oxide from the rocks dug from the volcano, and then I discovered bitter soil from limestone a few days ago, that is, magnesium oxide, and then I purified silicon from the sand. Mix them together, and mix some manganese to forge aluminum alloy, which is used for cylinders and pistons.

The cylinder head and other parts are made of cast iron and carbon steel. We have manganese, and the blast furnace at the base can produce materials!Thanks to alchemy, there is no need to worry about airtightness! "

"Where do you get your manganese?" Tesla asked.

"Volcano." Blitz Poland said, "At the foot of the mountain, I found it when I was digging. There is a manganese mine there."

It seems to be a place that Mendeleev didn't explore before, Tesla thought.

Manganese is also an element formed by volcanic eruptions, which is of considerable help to the steelmaking industry.

It can improve the strength, hardness, elastic limit, wear resistance and corrosion resistance of steel; in high alloy steel, it is also used as austenitic compounding element for refining stainless steel, special alloy steel, stainless steel welding rod, etc.

He looked at the internal combustion engine in front of him and carefully evaluated.

"In fact, cast iron can be used for the cylinder. Although aluminum alloy has good thermal conductivity and has advantages in weight, its strength, stiffness and vibration absorption capacity are actually inferior to cast iron.
Aluminum alloy cylinders are more suitable for automobiles. The light weight makes the car lighter, but for excavators, it is better to use cast iron engines.

Although the internal combustion engine is barely reproduced, the forging of the material lacks some key elements. The quality of cast iron, carbon steel, and aluminum alloy is actually not up to standard, and the lifespan is average. However, it can be used as a transitional period.

Subsequent materials can also be returned to the furnace for reconstruction.

Although the metal forging is very rough and the quality is not stable, but being able to forge such a complete internal combustion engine in this environment shows that you can learn well.

Your hands-on ability is very strong. If you have alchemy, you should be able to open a factory by yourself to produce internal combustion engines.

However, for us, oil is currently a fairly rare thing, and another technology can be tried. "

Blitz Poland was taken aback, not knowing what Tesla wanted to say.

Then, seeing Tesla stretching out his hand, he murmured softly.

"Essentially the same thing, with minor modifications."

The blue light bloomed from his arm, covering the entire internal combustion engine. The shape and material data of the entire internal combustion engine appeared before Tesla's eyes, and he operated it through brain waves.

About ten minutes later, a brand new internal combustion engine was formed in front of their eyes. At first glance, there was not much difference, but Blitz Poland could feel the earth-shaking changes inside.

Tesla took out a cylindrical object from his body and inserted it into the groove of the internal combustion engine, pulling the rope as well.

"Boom!!!"

Accompanied by the roar of the engine, bursts of exhaust sound burst out of the exhaust pipe, full of soul, and what is surprising is that the exhaust pipe does not emit black smoke, but transparent steam!
"What kind of fuel is this burning!?" Blitz Poland asked in disbelief.

"Hydrogen," Tesla said.

"hydrogen?"

"That's right. Compared with gasoline and diesel, hydrogen has a very wide flammability limit.

It exists as a gas at room temperature without atomization, and is easy to mix with air. It does not require many technologies such as in-cylinder direct injection and stratified combustion to achieve lean combustion.

The combustion flame of hydrogen spreads quickly and has a high calorific value. The energy released by the combustion of equal mass hydrogen is almost three times that of gasoline.

Under the combined effect of these two points, the temperature of the cylinder is higher than that of gasoline vehicles.

Based on the basic efficiency calculation formula of the Carnot cycle, increasing the temperature of the heat source is also the most effective way to improve the efficiency of the internal combustion engine.

Essentially, the principle of hydrogen-burning internal combustion engine is the same as that of gasoline internal combustion engine, so it only needs a little modification. "

"But hydrogen is far more difficult to control than gasoline." Blitz Poland said, "Its ignition point is too low, as long as there is a slight collision with the gas tank, it will be ignited and explode.

Moreover, there is also the problem of production. Hydrogen also requires a large amount of fossil energy to be produced, and electrolysis of water requires a large amount of electricity. "

"Indeed, so to realize the practical application of the hydrogen internal combustion engine, a technology is needed as a prerequisite." Tesla smiled, extinguished the internal combustion engine, and lifted the hydrogen tank out of it.

Under Blitz Poland's nervous expression, Tesla even split the hydrogen tank with a knife, but the expected explosion did not come.

Instead, a pile of transparent fragments poured out.

Blitz Poland's eyes widened suddenly, this is
"Solid hydrogen fuel." Tesla laughed.

"Metal hydrogen?" There was disbelief in Blitz Poland's eyes.

"There is still a difference from metal hydrogen." Tesla said, "That is the holy grail of high-pressure physics, the front of the fourth-generation nuclear bomb technology, and there is still a distance from us."

Blitz Poland nodded.

"Its technical principle is to use a nano-material ten times thinner than a hair, which can reversibly absorb hydrogen atoms to form a stable solid-state hydride, which can be heated when hydrogen atoms are needed. let go.

It is not disposable, and the solid hydrogen cylinder can be supplemented with hydrogen by injecting hydrogen.

Microcosmic operations at this level can be easily carried out with ether particles, and nanomaterials are carbon structures, so there is no need to worry about materials.

In the same way, we can use the reverse reaction of electrolyzed water to add an electrolytic membrane to make a solid-state hydrogen fuel cell. "Tesla said, "With this, if we can mass-produce in the future, we can even completely get rid of gasoline and diesel power." "

"Although the principle is similar, the hydrogen internal combustion engine is still different from the internal combustion engine.

Hydrogen has a fast combustion speed, fast flame propagation speed, and low ignition energy.If the structure of a gasoline engine is applied, the most likely problems are various problems such as early ignition, backfire and even deflagration. ’ said Blitz Poland.

"There is also the "corrosion" of hydrogen to metals. When the "corrosion" of hydrogen exceeds the limit of traditional internal combustion engine manufacturing metals such as steel, cracks will appear and eventually cause the engine to fail."

Tesla smiled, "Do you think I haven't considered it?"

Blitz Poland was taken aback for a moment, and then carefully looked at the hydrogen internal combustion engine in front of him. He seemed to have noticed some problems.

"The position of intake and exhaust has been changed."

He thought about it for a moment, and then his eyes lit up.

"Yes! The exhaust is integrated inside the engine, while the intake structure is placed on the outside.

In this way, the length of the intake duct can be reduced, and the impact of heat dissipation on the intake duct during the operation of the internal combustion engine can be reduced, resulting in the problem of early combustion caused by the high temperature of the mixed gas.

At the same time, it is also beneficial to increase the intake air volume of the cylinders on both sides in a balanced manner. After all, after the calorific value increases, the required intake air volume also increases correspondingly. "

Tesla looked at Blitz Poland with a little surprise. Although it was only a small modification, there were still a small number of people who could see the intention of this modification at a glance.

"Sometimes, some seemingly intractable problems can actually be solved with some simple ingenuity. I was designing the hydrogen internal combustion engine yesterday, and the modified structure is not just the jet intake.

You can take it back, take it apart and study it carefully.

But there is no need to spend too much time studying this, the hydrogen internal combustion engine is only used as a transitional thing. "

Tesla said calmly: "As far as the power plant that outputs mechanical energy is concerned, the superiority of the electric motor is beyond the reach of the engine.

High energy conversion efficiency, almost maintenance-free use characteristics, perfect output characteristic curve, abnormal speed range, terrible power density, excellent NVH, relatively low cost, and good space layout capabilities.

And very critically, the motor has the ability to recover energy, and the fuel-saving effect brought by recovering the braking energy is much higher than the 1% thermal efficiency of pressing.

Electric motors are the future of the future.

When I break through a small difficulty in the motor technology, the hydrogen engine will be useless, so don't worry too much about hydrogen ablation. "

"But the motor lacks a soul." Blitz Poland said.

"Soul?" Tesla frowned.

"The huge roar when the engine is running is like a tiger crossing the border when driving on the street." Blitz Poland said excitedly, "Just listening to the sound makes people feel happy physically and mentally."

Tesla was dumbfounded, "As far as the roar is concerned, the hydrogen internal combustion engine will indeed sound better than the fuel internal combustion engine."

"Then, what about hydrogen production? Electrolysis of water?"

Blitz Poland said, he knows that the base is not short of electricity.

"The conversion efficiency of electrolyzed water is too low, and the gain outweighs the loss." Tesla raised his hand, and blue light flickered on his arm.

Under the incredible expression of Blitz Poland, an ice edge appeared out of thin air in Tesla's hand.Under the brilliance of the sun, it shimmered and radiated a bit of cold air, and then turned into gas and dissipated in his hands.

"Using ether particles will save some money." Tesla said, "When we figure out how to maintain the atomic structure of metal hydrogen, metal hydrogen may also be realized, and the energy density can go to another level."

plop~
Under Tesla's astonished expression, Blitz Poland knelt directly in front of him, and he looked at Tesla with an extremely fanatical and excited expression.

"Boss! I want to play basketball! I want to learn alchemy!"

Fortunately, Tesla has become immune to the sudden reaction of the players. He reacted, looked at Blitz Poland, silenced the demand, but still said.

"You can see part of the modification of the hydrogen engine at a glance, which means that you have studied well and are indeed qualified to implant ether particles. I really need an assistant. Come with me."

"Yes!"

Poland jumped up excitedly from the ground and followed Tesla.

At the same time, another full server announcement came from people's ears.

[Player: "Blitz Poland" successfully produced the first internal combustion engine, obtained 6 achievement points, and loaded it into the achievement list. Please continue to work hard for other players. 】

"Blitz Poland? Which boss is this again?"

"The steam engine hasn't come out yet, so I just skipped a level and started an internal combustion engine? Awesome!"

"Damn it, is this the difference in the world?"

"Six achievement points, that's [-] military merits. Now that this kind of military merits are so rare, it's a waste of money!"

"Sour."

"Announcement on the whole server, it's too handsome, everyone knows the name."

The crowd was extremely noisy. This announcement obviously made the players extremely excited. Some were envious, some were jealous, and some fantasized about what it would be like to get the full server announcement.

The conversation between Tesla and Blitz Poland was naturally heard in Lincheng.

The solid-state hydrogen technology should be the old era technology that Tesla reproduced in order to repair the electromagnetic gun. The solid-state hydrogen battery is enough to provide energy for the electromagnetic gun.

Let them temporarily spend the days of lack of oil,

And it is light, even some simple exoskeletons can be powered by this battery.

In the future industrialization, this kind of battery is simply an artifact.

If Blitz Poland can realize this technology in reality without alchemy, it will definitely be revolutionary for the progress of China Battery energy technology.

Although Lincheng can't contact the government too directly, the strengthening of the power of the government is undoubtedly a positive help for his ultimate goal.

However, before that.
Suddenly, Nuwa's voice came from the ears of all the players.

"The special plot mission starts: when the night falls, follow the arrangement of Nvwa and attack the Prometheus base! Take back the property belonging to the united front!
All players above the second class, go to the training ground to gather. "

Before that, take down their industrial parks.
