From Wang Chengen's mouth, Chongzhen learned that the steam engine led by Fang Yizhi had also been successful, which was really a blessing! After Chongzhen inspected the steam turbine trial-made by King Ding in the morning, he couldn't wait to come to Fang Yizhi's steam engine factory in the afternoon, wanting to see what the steam engine in the 17th century looked like.

The seized submersible is undoubtedly very valuable and has great help in the development of steam engines, generators and motors. The pressure gauge above is the baby, which can at least make the pressure gauge and thermometer of the Ming Dynasty more accurate. The pressure gauge on the submersible is removed and used to make reference pressure gauge and thermometer to calibrate pressure. After the temperature, at least, the operation safety of the steam engine and steam turbine looks more secure. Of course, the biggest gain is the multimeter equipped with the submersible, and the PDA carried by the Yoshino Temple, which makes Wang Chengen feel like he has gained a treasure. With the multimeter, it is even more convincing to do the electrification career of the Ming Dynasty. As for the PDA, Wang Chengen is planning to use it as a computer. Of course, there is no large-scale operation now, but at least the square sum trigonometric function is too convenient with it.

Wang Chengen did not let him be idle for this guy in the temple. He had delicious food and drinks every day. The job he had to do every day was to write textbooks. It was a bit exaggerated to write textbooks. The reality was that this guy was thinking about it every day, reviewing everything he had learned in middle school and college, and writing everything he could think on paper, that's all.

The prototype of the steam engine can actually be turned three months ago, but it is still a long way from being able to be put into operation.

It is impossible not to say that the craftsmen in the Ming Dynasty were really exquisite, especially the craftsmen in Zhejiang, which made Fang Yizhi sigh. Not to mention Sun Yunqiu's attainments in telescopes and microscopes, even ordinary craftsmen were much more skilled than those in Beijing, and many craftsmen even surpassed Wu Qingfeng's level. Wang Chengen was even more surprised. In terms of handicrafts, the craftsmen's craftsmanship was superb, which allowed Wang Chengen to truly understand what "sensible and skillful" means. When trying to make the steam engine, Wang Chengen just drew a sketch. All connecting rods and crescent plates were made by these craftsmen, only pistons and cylinders were processed by lathes and boring machines.

When Chongzhen came to the factory, he saw an absolute steam locomotive. However, this steam locomotive is a real economical type and is a concentrated version of the huge steam locomotive in later generations. The heart of this steam locomotive is already the second generation steam engine of the Ming Dynasty.

The prototype of the first generation steam engine is a bit simple. It looks like a can on the stove. A pipe is out of the can and connected to the cylinder. There is no ball valve in the middle. The fire is burning, and the steam drives the cylinder. The cylinder pushes the connecting rod. The connecting rod then drives the crankshaft and then drives the flywheel to rotate. The connecting rod also moves accordingly, moving forward and backward in an orderly manner. This prototype is just to verify a principle. At the beginning, a group of craftsmen were shocked. After a long time, the craftsmen understood some of the exquisiteness. After learning from one example, they learned from one example and learned from it, making the trial production of the second generation steam engine much easier.

The first generation of steam engines here are constantly rotating, while the steam locomotive begins to ignite and preheat the boiler. Fang Yizhi is preparing to let Chongzhen take a closer look from beginning to end. He does not think that the emperor has more knowledge in steam engines than him. In order to be more vivid, Fang Yizhi first took the emperor to see the wooden model next to him, and introduced:

"After the first prototype is transformed, it is no longer difficult to test the second generation steam engine. Before the second generation steam engine is trial-making, just like the first generation steam engine, we should make a wooden model first. For the connecting rod structure design and modification, the movement trajectory of the cylinder and connecting rod are simulated on the wooden model to ensure that the movement of the sliding valve is synchronized with the movement of the piston. Please see the emperor."

This wooden model only simulates the movement of the piston connecting rod and crank. The cylinder is a section model. The movement of the piston and sliding valve can be clearly seen, which is like a teaching model. Well, this is a good teaching model! The wooden model of the first prototype is also on the side, but it is far less exquisite than the second-generation prototype model. At this time, the movement of the second-generation prototype model is demonstrated - when the piston is at the rear end, the sliding valve is to the rear end in steam inlet and steam exhaust position; when the piston reaches the front end, the sliding valve is to the front end in steam inlet and steam exhaust position. Use your hand to move the piston back and forth, drive the crank connecting rod structure, and then drive the flywheel to rotate. Chongzhen thinks this method is really great. He might as well make a wooden model for his own tank project.

Chongzhen pulled Wang Chengen aside and whispered:

"I said Wang Chengen, the first steam engine created by the British in history. I suspect that I would first build a wooden model, get a little bit together, and then I will make a crank connecting rod system, and then follow the examples. Then I invented the steam engine. Do you think this is the case?"

Wang Chengen looked at the model, nodded, and whispered:

"I think so, it's hard to believe that the British could calculate the four-link structure so accurately so early. The emperor said it well, and it was probably how it was slowly made up. Haha!"

Wang Chengen thought to himself, no matter how they created the steam engine, they did it first. Later people, especially the Chinese, would have only copied others for a while. But now it is different. The Ming Dynasty was the first to invent the steam engine, and in the future it can only be copied by others, including the British. Looking back, since the damn Japanese traveled through time, the status of the inventor has been challenged. In the eyes of the Japanese, this is just a copy of later generations, and it is very likely that the Japanese are also doing such plagiarism. When they think of this, Wang Chengen was a little depressed!

At this time, the steam locomotive had completed the preheating of fire. As the steam valve was opened, the cylinder began to drive the link movement, and the steam locomotive began to slowly start. Of course, this steam locomotive was not a giant like the steam locomotive in later generations. It was just a two-ton guy and did not carry a coal truck at all, so there was no need for rails and could start on the flat ground. The steam locomotive could not turn, and there was no brake device installed, so after starting for a distance, it could only force the steam locomotive to be stopped by using cables to tie steel piles.

I have to say that this is still some distance away from a truly operational steam locomotive. To build a railway, the steam engine must at least be equipped with pneumatic brakes. The days when the railway was built in the Ming Dynasty were not far away, but now is not the time.

After the steam locomotive stopped, Chongzhen got on the car and looked at it, and found that the pressure gauge and water level gauge were all in place, which was not on the same level as the steam locomotive he had seen in the 20th century, but this was an amazing achievement, which was really gratifying.

From the furnace, you can see water pipes in the furnace, but this does not look like a water pipe boiler. Chongzhen grabbed Wang Chengen and asked:

"Wang Chengen, is this a water pipe boiler? Why do I think it is different from the water pipe boiler of a steam turbine!"

"Oh, this is a water and fire tube boiler. The water tube is used for limited use. The pressure of the steam engine cannot be too high, because the seal in the cylinder is multi-turn cast iron ring, so the water and fire tube boiler is used. In this way, the pot shell can be made relatively small, the thermal efficiency is high, and the output is high."

Heard that the steam engine weighs only two tons, Chongzhen immediately thought of the tank's power problem. The two-ton steam engine was still acceptable. Chongzhen hurriedly pulled Wang Chengen aside and asked anxiously:

"Can this steam engine be used as the power of a tank?"

"Your Majesty, it seems that this steam engine is not so suitable for use in tanks. I remember that when the war ended, the Americans made two tanks that used steam engines as power. One of them was a fire-breathing tank, which used the high pressure of steam to blast fire. However, this tank was more than 10 meters long and weighed 44 tons. Although it was heavy, its armor protection was very poor. In the end, no one cared about it and disappeared into the long river of history. Your Majesty. The steam engine is too big, and as a tank power, it may not be worth the effort."

"Oh, you're right. But if you make a split pose, the power car and the tank are separated, I wonder if it's OK? We have a steam locomotive with tracks in front and pull the tank with a wire rope. Isn't that enough?" Chongzhen thought about the tank these days and nights, but now he has even expressed his idea of ​​split pose.

Haha, split type, do you think it is an air conditioner! Wang Chengen tried his best to imagine a crawler steam locomotive in front pulling the tank car behind and rushing into the battlefield. He couldn't help laughing. After laughing, he still expressed his own opinion:

"Your Majesty, if this is the case, this tracked steam locomotive is almost the same as a rescue tank. It is said that only after the tank cannot be driven, this rescue tank will come out to rescue. My Emperor, if he just pulls it in front and back, it will be impossible!"

Chongzhen thought to himself that if there were diesel engines and gasoline engines, there would be no need to discuss the power of the steam engine at all. Isn’t that okay? When the diesel engine gasoline engine was launched in the Ming Dynasty, I don’t know what time it was! Besides, even if the steam locomotive in front was broken during the war, can it still be driven by humans? No matter how bad it is, it is a fixed turret. Chongzhen had decided to think about it and said:

"I care whether he is a rescue tank or not. Anyway, our strategy is to not seek excellence at first. At the beginning, we only need to have it. After that, we will improve on this basis. In this era, if we have no one, we will take the lead. In my opinion, we cannot be too conservative. Everything needs to be measured by the standards of the future generations, and then nothing needs to be done! Do you think so? Lord Deng said it well, it doesn't matter if he crosses the river by feeling the stones. It doesn't matter if he does it wrong. If we have the knowledge of the future generations, we will never be wrong. So what are you afraid of! I will do everything, and only then can we find problems when we do it. At least we can take some detours. In this process, we can at least cultivate a group of experienced talents. Do you think so? Well, steam turbines are the product of leapfrog development. I think it might as well be more courageous and faster. Otherwise, if the Japanese run far ahead, we will not be able to catch up at that time!"

When the Japanese mentioned, Chongzhen remembered the Japanese's Nanjing Massacre. When the Japanese thought of the Japanese, they captured Nanjing with the Type 94 bean chariot. A company of Chinese soldiers barely killed one bean chariot, and their hearts were only bitter. Chongzhen's emotions were a little excited, his eyes were a little wet, and his voice changed a little:

"If you fall behind, you will be beaten! Whenever you think of the Japanese bean chariots that can rage in China, you want to build tanks one day earlier. Think about it, the Japanese who traveled through time have ready-made advanced guns that can be used to imitate. Maybe both submachine guns and machine guns have been built at this moment. We may suffer the Luzon offensive and defensive battle! How can I not be anxious!"

Wang Chengen had thought about the advantages of the Japanese, but he couldn't even come in a hurry. However, the emperor made sense. Now he can't just pursue success rate, but also pursue speed. This can not only accelerate the development of military industry, but also force a group of talents. Thinking that King Ding could also stand alone, Wang Chengen finally figured it out and let it go when it should be released. The emperor wants to build steam tanks, which may be the same as a way. If the effect is not ideal, just treat it as cultivating talents! So Wang Chengen said solemnly:

"Okay, let's do it according to the emperor's opinion. Fang and I will use IQ to develop a crawler steam locomotive plan, and start trial production immediately after it is made."

After saying that, he sighed and said:

"Originally, my idea was to start building the railway after the steam locomotive was successful, but it required a lot of steel to build the railway. Now I really can't afford it. It's a pity!"

Chongzhen shook his head and said:

"We only have this little steelmaking capacity. We need to build ships, tanks, guns and railways, so we should save money! The top priority of developing transportation is to develop water transportation, and shipbuilding is the top priority. Installing the steam engine and steam turbine onto the ship as soon as possible is the top priority!"
