Facing Zhang San and others who were extremely curious about knowledge, Zhu Zhanzhen first analyzed the current problems of steam and asked people to turn on the welded steam engine.
"The relationship between the piston and the inner wall of the device is not smooth enough. It needs to be as smooth as possible, otherwise it will be easily damaged. Because now the steam engine can only run for a while, so the piston has not been damaged yet, but my ideal steam engine must be able to run for several times."
years or even more than ten years.”
"Don't worry, sir, we will try our best to find ways to continuously improve this aspect." Blacksmith brothers Li Si and Li Yu assured, patting their chests.
Zhu Zhanzhen nodded: "Except for this, the efficiency of the current steam engine is not good. I have an idea. Now the steam is introduced through a pipe. Next, we will make two pipes, and the other pipe is introduced into the pipe.
The other side of the piston."
"Young master, if the steam is introduced from both sides, the piston will be sandwiched in the middle." Zhang San immediately raised a question.
Zhu Zhanzhen couldn't help but praise Zhang San's imagination and insight: "Enter, but not at the same time, certainly not at the same time, but you can take turns."
"Take turns? How to take turns?"
Zhu Zhanzhen pointed to the pressure relief port. At this time, after several people's continuous attempts, the pressure relief port could be opened and closed with the movement of the connecting rod.
"Master Zhang San, let me ask you, how do you determine the time when the pressure relief port opens."
"Try many times to find the position where the piston is compressed to the innermost position."
"But just relying on the pressure relief port to relieve pressure will cause the piston to fall back slowly. Now our steam engine piston moves up and down. It can be changed to parallel front and rear. Another steam pipe guides the steam into the rear of the piston to accelerate
Its return movement opens and closes at the same time as the pressure relief valve."
Zhang San was in trouble. He thought it was feasible, but he couldn't draw a perfect picture in his mind.
Zhu Zhanzhen then pointed at the existing steam engines and explained bit by bit. Fortunately, his posture in this aspect was quite solid. After one explanation, Zhang San and others had a general understanding.
Zhang San couldn't help but sigh: "Young Master is really a man of great talent. If we had to study the improvements just now, I might not be able to complete them within three to five years."
Zheng He said: "Next, everyone will create it according to the young master's ideas. If there is anything you don't understand, summarize it to me every day. I will go to the palace to communicate with the young master every once in a while."
"Master Zheng, it's better for me to come out. It's inconvenient every time you have to have someone carry the iron guy into the palace. I leave the palace once every seven days."
"Then I'll trouble you, sir."
Zhu Zhanzhen suddenly said: "Also, Mr. Zheng and all the masters, you can just study the steam engine, and don't worry about the experiments installed on the car."
Zheng He looked troubled: "But I'm afraid it's hard to know its effect if it's not installed in a car and tested."
"I already have a solution. I will think about it more when I get back and tell you. The steam engine is the most important. There is no need to worry about the effect of loading."
"Okay, just follow what the young master said."
As long as the steam engine can rotate and the gears are connected to the tires, it can become a rear-wheel drive vehicle. The current technology must be to connect the rear wheels, and the principle is just like that of a four-wheel drive vehicle.
It's even simpler than a four-wheel drive car. A four-wheel drive car also uses a rod with gears to connect the front wheels to create four-wheel drive. But today's cars don't need it. They only need rear drive and the front wheels do the steering.
Moreover, the final form of the steam car in Zhu Zhanzhen's mind was a train. He just wanted to build the steam car first and show it to the emperor to seek funding.
The steam engine was too noisy and had to constantly burn coal. We couldn't let the emperor sit on a pile of coal. Steam trains were the way to go.
It was the same in the previous world, where steam engines were used on trains.
When Zhu Zhanzhen thought of trains, he also thought of rails. Without rails, trains cannot run, and compared to flat cement roads, rails are indeed more cost-effective.
"Master Zheng, can you show me the iron smelting workshop?"
"Sir, the environment in the workshop is poor, you..."
"It's okay, take me to see you."
The smelting workshops of this era, even those under Zheng He's fleet, looked like small workshops. You could see a group of shirtless men beating continuously, and the hot red molten iron flowed out. Most of the steps required manpower to complete.
Smelting is also a high-risk project. Because of the scorching heat, most workers don't wear shirts or wear light tops. Once the molten iron splashes, there is no protective effect at all.
After Zhu Zhanzhen looked at it, he nodded with satisfaction. Although the craftsmanship was backward, the professionalism of the craftsmen really made him feel refreshed.
He nodded and took out a pen and paper to draw a picture. Zhu Zhanzhen's drawing skills are also very good, thanks to the solid foundation of the original owner of the body. Otherwise, Zhou Xinghe's own painting skills are basically a master of abstraction.
class.
Zheng He looked at the Tushan railway track and fell into deep thought, having no idea what it was.
"Mr. Zheng, I call this a railway track. There are two railway tracks, and the bottom is made of wood as a base. From now on, steam cars will run on the railway tracks."
Zheng He was even more puzzled: "Fifth Young Master, why don't you run on the road instead of running on the railway track?"
"Two advantages, one is stability, and the other is cheap."
"Oh?" Zheng He didn't think it was cheap to make railway tracks.
Zhu Zhanzhen answered questions and answered questions: "Although the steam train you demonstrated in front of His Majesty before, Mr. Zheng, did not run a long distance, you have also seen that if it moves on the ground at its speed, it will be very bumpy if it is slightly uneven.
It can be very smooth.”
"What about cheap?"
Mr. Zheng, imagine if it were to build hundreds of miles of official roads in the future, which would be cheaper compared with hundreds of miles of railways.
When Zheng He thought about it, he immediately understood that since the steam car was built, it must be run all over the country. The steam car obviously cannot travel on small mountain roads. It must be an official road. The cost of official roads is high, and there are countless manpower and material resources.
.
Seeing that Zheng He had come to his senses, Zhu Zhanzhen continued: "Master Zheng, you can have someone make a section first to try it out. Each section of rail can be made within the length and total amount that can be carried by manpower, and it can be connected end to end."
"Don't worry, Fifth Young Master, I'll give the order right away."
Every time Zhu Zhanchen came, he would bring them new things, and a group of craftsmen gathered around Zhu Zhanxi to offer them as if they were treasures.
…
Zhu Zhanzhen was studying steam engines with Zheng He, while in the palace his fat father frowned: "Hey."
"Father, why bother? It's right not to add some servants to your younger brother. You see, the two younger brothers from the second uncle's family are always followed by a group of servants when they go out."
"Then I'll teach the boys how to be spoiled."
Zhu Gaochi said he was helpless, but he had to obey the emperor's order: "Zhan Ji, go and tell Ruowei and ask her and Hu Shanggong to prepare candidates and choose two maids for themselves. Forget the bed warmer, they themselves
We all have maids, so let’s choose two each.”
Zhu Zhanji said with some embarrassment: "Father, my fourth brother told me a few days ago that his personal maid behaved in some arrogant ways and he wants to change her."
Zhu Gaochi was stunned: "What kind of transgression?"
"I climbed into my fourth brother's bed in the middle of the night."
"What?" Zhu Gaochi was furious: "What happened to the fourth child?"
"Although the fourth brother is a little thinner, a palace maid can still fight. I just don't want to publicly punish the fourth brother because of his face. I originally wanted to find a reason to punish her, but this time I took this opportunity to replace her.
."
Zhu Gaochi nodded, as if he had thought of something: "The fourth child really didn't let her take advantage of it, right?"
"Probably...probably not. The fourth brother is still young, so...not yet...well, there shouldn't be."
