After lunch, Yang Fan directed the workers to install the miniaturized steam engine.
This steam engine was actually ordered by Yang Fan in modern times. It was customized with the help of a master from the Rose and Guns Friendship Group.
By the 1930s, steam engines were basically mature enough to be installed in cars. It's just that internal combustion engines don't need to add water frequently and are more efficient, so steam engines were eliminated.
Chen Xi was surprised to find that Yang Fan's steam engine didn't look big, but it actually had three pistons and cylinders. His mouth opened in surprise. She didn't know why it was designed like this.
"Have you measured the temperature of the gas discharged from the cylinder?" Yang Fan asked.
Chen Xi shook her head. She had never measured this before.
"If you imagine, you can understand why steam can push the cylinder and piston to move. It's because water changes from liquid to gas, its volume expands, and the air pressure pushes up the piston, right? A cylinder is an expansion steam engine," Yang Fan said .
Chen Xi thought about it and found that this was indeed the principle. She asked: "Sir, can a steam engine have multiple cylinders?"
"Yes, when the first cylinder completes its work, the steam will be discharged. Note that the temperature of the steam at this time is very high, and it will be wasted if it is discharged directly. You can enter the second cylinder to continue to perform work and push the piston to move. Then enter The third cylinder. After three consecutive times, the temperature drops and there is not enough energy, so it can be discharged. In this way, the thermal energy can be fully utilized and the thermal efficiency can be improved. A steam engine with three cylinders working continuously is called a triple expansion steam engine."
Chen Xi heard it as if there was a flash of lightning in the dark night, and he understood it completely at once.
"However, don't be too ambitious. You can barely walk now, but you can't run. We can't build this machine now. Let's understand the technology of the one-expansion steam engine before talking about anything else. The three-expansion steam engine is built for steel in the future. The power system prepared by the ship will not be used by us for a while."
Everyone watched as the engine was assembled, then the gearbox. This thing is high-tech, and Chen Xi spent a lot of energy studying it.
Then the brake system was installed. Yang Fan used the earliest automobile drum brake designed by William Maybach in 1900.
The principle of this thing is very simple, it just requires some materials. Once the basics are explained, everyone will understand.
Finally, install the water tank and fuel tank on the car. The floor is installed on the chassis and the two rows of seats are installed. The seats are all leather sofa seats.
Finally, the outer shell frame made by carpenters from mahogany was installed. Fixed to the chassis by riveting. The last step is to install glass on the car windows.
The front engine cover can be flipped up on both sides, somewhat similar to the old Jiefang cover, making it easier to maintain and add water and fuel. There is a large trunk in the back for luggage.
After the entire car was assembled, everyone's eyes lit up.
Lin Yueru and Xiao Niangpi rushed to open it. was rejected by Yang Fan.
This car is actually an antique design for modern enthusiasts, and many of its spare parts are designed and manufactured there. Yang Fan is just assembling it here. Otherwise, why would one be produced so quickly?
The top speed of this car has exceeded thirty-five kilometers per hour. The car has three forward gears and one reverse gear.
Except the steering wheel has no power assist and is dead. Others are not much different from the steam cars of 1920. Xiao Niangpi and the others have never had a driver's license or driving training, so Yang Fan doesn't dare to let them go crazy.
It doesn't matter if you bump into someone else or one of your own.
"Master, I want to ride in your car." Seeing that there was no hope of driving, Xiao Niangpi immediately shook Yang Fan's arm and begged.
"Sir, I want to take a ride too." Lin Yueru was also red-eyed and strongly requested to take a ride in the car, and asked Yang Fan to teach her how to drive the car.
Yang Fan had no choice but to let them sit in the front row. Three people can sit in the front row, just like taxis on Hong Kong Island. Chen Xi and Zhang Shize were sitting in the back row. Then I drove around the yard a few times.
Yang Fan discovered that besides the trouble of ignition, this car needed to be lit with an open flame. You still need to preheat, wait for the water to boil, and the steam pressure reaches the required level before you can drive. Driving is actually quite simple.
The speed of more than 30 kilometers is really not very fast. That is the third gear in later generations. It doesn't accelerate much at the start.
Yang Fan didn't expect that he seriously underestimated Xiao Niangpi and Lin Yueru. Soon he and Zhang Shize were driven out of the car by three tigresses. They drove themselves for a walk.
Zhang Shize was also found and taken away by someone from his family soon after. Only Yao Guang was left with him.
"You came from Zunhua, is there something wrong?" Yang Fan asked.
Yaoguang is a homebody who doesn't like socializing and rarely leaves Zunhua. She set up an energy absorption coordinate there. Recharge your system. It seems inconvenient to change.
"I'm here to tell you good news." Yao Guang said with a smile.
"Can I go back? The passage has been reopened." Yang Fan asked in surprise.
Yao Guang rolled his eyes and said: "I just want good things, what are you thinking about? We can set up a second teleportation point in modern times. If you have anything that is inconvenient to teleport, you can put the teleportation point outside the country."
"You mean, we can establish a second teleportation point without going back."
"Yes, have you ever played Red Alert? As long as you have a base vehicle, you can set up a new headquarters. I will pass a box over, and you ask your people to find a place to settle abroad, and I can set up a new headquarters. area." Yao Guang said.
Yang Fan felt excited.
In modern times, he has attracted a lot of attention, which is not a good thing for him. It made him dive for a long time.
He urgently needs to find a new development base where no one is paying attention, or where the environment is friendly and he can play his best.
In this kind of place, generally the more backward and chaotic the area, the better. After all, it’s easy to fish in troubled waters.
Yang Fan calmed down his excitement and asked: "Do you have any good places? Recommend one to me."
"After learning the news, I checked it out for you. At the junction of countries S and K in East Africa, there is a company owned by Gaul Chicken, which has built a shipyard and farm. Because the world economy has been in recession in recent years, They are already heavily in debt. They are planning to sell it and leave. This dock has a closed roof, so the transmission is relatively concealed and is not easily discovered by satellites. You may consider it."
Yang Fan was startled. That country seems to be in chaos.
Not only are there many warlords, but they are always fighting each other. It is really a real-life version of the king's flag changing on the city wall. There are also many guys there who are equipped with a pair of flip-flops, an AK47 and a pair of swimming trunks, and they go to the sea to make a fortune in an assault boat.
"That land is a full fifty square kilometers and is close to the border. As long as you pay taxes every year, the local warlords don't care what you do. They won't care if you play fighter jets in your territory."
"Is there only one dock in such a large piece of land?"
"In addition to a ship repair yard, there are more than fifty houses. The rest are farms. There are also some local people working, not to mention the efficiency of these people's work. In short, you can build according to your own ideas, you are here There is no shortage of money in modern times. The money from the last gold sale is still in the bank."
No more today
