Drive the RV back to Datang

Chapter 704 Chapter 723: Helicopter Engine
After returning from Wei Zheng's mansion, Li Hao drove the RV out to Nantuo Mountain. Li Hao and Lu Yun sat in the driver's cab, while Feiying and other special forces stood in the carriage, giving him the impression of a bus.

In order to avoid fatigue driving, Li Hao and Lu Yun took turns driving. Lu Yun has good driving skills, and this road is wide concrete road, as smooth as possible.

They didn't drive very fast. They arrived at Nantuo Mountain at three o'clock in the morning. The cement road leads to the bottom of the time-space tunnel. Looking at the cement road leading to the mountain, Li Hao felt worried: "This cement road leads directly to the time tunnel." There, someone will definitely walk there along the road, and the mobile phone that my brother sent must have been picked up by someone."

Feeling apprehensive, Li Hao finally drove the RV to the end of the cement road, which stretched all the way into the mountain depression. The concrete road was built just to drive the RV out.

Li Hao got out of the car and checked, and was pleasantly surprised to find an iron box for desserts on the ground, which obviously did not belong to this era.

"It's still there." Seeing this, Li Hao hurried forward to pick it up, and muttered to himself, "That's right, there is no one living here for sixty or seventy miles, so why would anyone come? I don't know if Master is in the Taoist temple... ..."

While talking, he shook the iron box in his hand, feeling something inside, Li Hao opened the cover, and saw a whole new set of mobile phones, covered with a layer of waterproof plastic film.

"Wow, photovoltaic mobile phone?" Li Hao took the legendary high technology in his hand and took a closer look, and found that the mobile phone is so thin. Sure enough, the more advanced the technology, the better the mobile phone is, but Li Hao didn't find the photosensitive Since it is a photovoltaic mobile phone, it absorbs solar energy for charging, so it must have a photosensitive board, but Li Hao couldn't find a photosensitive board.

Li Hao took this new mobile phone to the car, studied it carefully, and finally turned it on successfully, and then entered the mobile phone interface. Fortunately, the operating system is similar to the previous operating system, and the changes are not very big. Li Hao can basically use it , Using this mobile phone to call his own number, he actually dialed through. It seems that there is a card in the new mobile phone, so he immediately wrote down the phone number.

Send a message to Li Cheng, Li Cheng said that he is busy and has no time to chat, and we will talk tomorrow, Li Hao knows that he must be running around preparing those things for himself.

Li Hao opened the car door and asked all the special forces to get out of the car and walk around to get some air, because it was always too stuffy in the car.

While walking, someone suddenly exclaimed in the distance: "My lord, there is a strange thing here!"

When Li Hao heard the words, he hurried over and saw that it was a helicopter. No wonder he said it was a strange thing. The helicopter fell from a tree branch at some point. He was unlucky. He hit the ground on his face first, and the cab was smashed. The wind and rain erosion, has been dilapidated.

Li Hao walked around the helicopter for a long time, and suddenly thought: "The engine of this helicopter should not be broken, right? Dismantling this engine and sending it to Cheng Qingyun will make the internal combustion engine appear decades earlier."

As soon as he thought of this, Li Hao couldn't bear the thought anymore, and immediately went back to the car and took out the big tool box to dismantle the helicopter's engine.

It is not easy to disassemble the engine of a helicopter, but if you don't care about the integrity of other parts, it is easy. If you can't get it open, just use an ax and a hammer, as long as it doesn't hurt the engine.

With the joint help of everyone, it took Li Hao nearly four hours to dismantle the engine. Good guy, it's big and heavy. Fortunately, Li Hao's compartment is very big, just enough to put the engine in.

Next, it was a boring wait. Li Hao went to Jingyun Temple to take a stroll, and found that no one lived here for a long time, and the furniture on the ground was full of dust.

Finally, another day later, in the early morning, a message came from Li Cheng: "Everything is ready, and I'm on my way to my destination."

Li Hao replied: "Got it, I'm already waiting."

After waiting for a long time, around noon, Li Cheng sent another message: "I'm starting to vote!"

Li Hao replied with one word: "Okay!" Then he looked up at the sky with the others.

After waiting for about 3 minutes, a black object suddenly appeared at a height of hundreds of meters in the sky. It was small at first, and then grew bigger and bigger, as if it was drilled out of something. It turned out to be an aluminum alloy box. After the alloy box appeared in the air, it was like a leaf, swaying left and right, floating down, falling very slowly, as if it had no weight.

Immediately afterwards, the second aluminum alloy box appeared, the third, the fourth...

All five large boxes appeared in the sky and fell slowly. Li Cheng sent another message: "There are five boxes in total, have you received it?"

"Received." Li Hao replied to the message, and waited patiently for the boxes to drop down.

After the box fell, Li Hao stepped forward to open the combination lock to check whether the items in the box were damaged. After checking all five boxes, nothing was damaged. Li Hao got up and waved his hand, saying: "Move them all to the car." !"

All the special forces stepped forward to lift the box and moved it to the RV.

There are five more large boxes on the car, and the space for the special forces is a bit small. Everyone squeezed together, and they can still fit in. Li Hao sent a message to Li Cheng: "Brother, I have something urgent and I have to drive to Chang'an , we will talk later when we have time."

Li Cheng replied: "Okay, we must keep in touch, don't worry me and my parents."

"En!" After Li Hao replied this message, he turned around and drove to Chang'an.

The RV is powered by electricity and can drive up to more than 100 yards, but Li Hao is worried that it will be bad for the motor. The fastest speed along the way is only [-] to [-] yards. This speed was already equivalent to flying in ancient times.

That night, they arrived in Chang'an, but it was dark now, and the gate of Chang'an was closed long ago. Li Hao first drove the car to Lantian's scientific research institute, and handed over the helicopter's engine to Cheng Qingyun. The helicopter's engine belongs to the aviation piston type. The engine burns aviation gasoline. It works on the same principle as a general car engine, but with higher power and lighter weight.

The reason why Li Hao wanted to disassemble the helicopter engine was to use this engine as a sample to research a fuel engine, no matter what kind of oil it was burning, it was more powerful than a steam engine. Although the appearance of the steam engine was epoch-making, it The power is really not high.

When Cheng Qingyun saw the engine on the ground, Li Hao smiled and said: "Qingyun, guess what it is."

Cheng Qingyun circled the engine twice, pondered: "This is a kind of machine."

Li Hao nodded and said, "That's right, it's a machine. Can you guess the function of this machine?"

Cheng Qingyun squatted down and stared at the engine carefully for a long time, and found that the mechanism was extremely complicated, and he was dazzled. However, he was the inventor of the steam engine, so he still had a deep understanding of the mechanism, especially the functions of some parts. It can be seen, so, after looking at it for a long time, he got up and looked at Li Hao, and asked, "Teacher, this is not a power machine like a steam engine, is it?"

Hearing this, Li Hao looked at him in surprise, reached out and patted his shoulder, and said, "Sure enough, it's a professional. You can tell it at a glance. That's right. This is a kind of power machine, and its power is much higher than that of a steam engine."

"Hmm!" Cheng Qingyun looked at the engine excitedly and asked Li Hao, "Teacher, how much do you know about this power machine? Can you introduce it to me?"

Li Hao smiled and said: "This thing is called a fuel engine, also known as an ignition-type internal combustion engine. It generates internal energy by burning oil, and then converts it into mechanical energy. If you want to understand it, I only know a little bit. It is to atomize the fuel and spray it into the cylinder for combustion, as you know, the atomized fuel must be fully burned, and the power will naturally be high.”

"En." Cheng Qingyun took out a pen and paper to record Li Hao's words, then raised his head and asked, "Teacher, can any kind of fuel be used for this fuel engine?"

"Of course not." Li Hao shook his head and said, "This thing has very high requirements on oil, it must be extracted from petroleum."

Cheng Qingyun said: "We have also refined oil according to your instructions and obtained different types of oil. Teacher, which kind of oil are you referring to?"

"This...it's up to you to explore slowly." Li Hao said, "There are different types of fuel engines, some can burn diesel, and some can burn gasoline. I haven't studied the differences between gasoline and diesel. However, this is really up to you.”

"Okay, thank you teacher." Cheng Qingyun said, "Teacher, I will study this internal combustion engine carefully. It may take five years at the earliest, or ten years at the slowest. I will definitely be able to build you a car powered by a fuel engine."

"Well, I believe in you as a teacher." Li Hao nodded with a smile, and patted Cheng Qingyun's shoulder vigorously again, "You are the father of technology in my Datang!"
