Peng Qinfang certainly knew about the "three-year plan", and Lao Peng also agreed with the focus on the development of gas as fuel.

Time travelers in the SAR can now enjoy the convenience of tap water. If gas is connected, then it will probably not be too far to enjoy the shower brought by the gas water heater. This is really something that travelers who are used to showering almost every day in later generations.

The preparation of gas does not have much technical content. At the end of the 18th century, the British began to prepare gas with coal. The early gas was collected in coke ovens and used as fuel to burn it very well. For this reason, the British Empire gave it a very touching name - "Suitable Fire". The only disadvantage is that the taste is a little worse and smells a little smell. The reason is that it has no reliable method to purify gas. However, this purification problem is not a big deal for time travelers, because the smell is mainly due to hydrogen sulfide. In terms of environmental protection in later generations, sulfur removal is a basic skill, so time travelers still have some tricks.

Because of this, Lao Peng doesn’t think it’s difficult to produce gas.

Lao Peng thought of other problems.

"Teacher Mao, alcohol is liquid, gas is gas. I remember that taxis in later generations need to be modified to renovate liquefied gas, right! Now, the ball-type internal combustion engine of soaked alcohol has been successful. I wonder if it is difficult to change gas?"

Mao Geng patted Lao Peng on the shoulder and said:

"Let's go over there and you'll know."

When they arrived at a room near the corner, Mao Geng’s two disciples were fiddling with a device on the tool table.

This device is not large in size, it is a small thing. It is fixed on the workbench. One disciple is shaking the handle, and the other disciple is touching around. Lao Peng didn't understand what they were doing for a moment.

After a while, the disciple who shook the handle turned the nut cap on a certain copper tube. With a "bang", he saw the mouth of the tube squirting out quickly, causing a harsh whistle. Old Peng seemed to have guessed something, and was about to make a sound, Mao Geng smiled and said:

"Look, you see, this compressor is OK."

It turned out to be a compressor. Old Peng's eyes lit up and he praised:

"I think it's OK. The pressure on the jet just now will not be small."

After watching for a while, Lao Peng basically understood that this thing is actually similar to a short pump. The up and down reciprocating movement of the air is not driven by the hand pressing foot, but is driven by a crank connecting rod mechanism. With such a crank connecting rod piston mechanism, the rotation movement is easily transformed into reciprocating movement. To put it bluntly, it is still a reciprocating process. In addition to the cylinder piston, it is nothing more than an intake check valve and an exhaust check valve. In principle, it is not much different from a bellows.

Lao Peng thought at that time that with such a crank connecting rod mechanism, it could easily turn artificial inspiration into mechanical inspiration. From this point of view, the crank connecting rod mechanism is simply an upgrade artifact of this era. Isn’t it! Just before my eyes, it magically upgraded a pump to a compressor.

The cylinder of this compressor is made of brass and looks very delicate, probably for sealing.

Lao Peng could guess that Mao Geng’s two disciples should be testing whether they leak. Look at it, the problem of leaking seems to be a bit tricky.

For a moment, Lao Peng was a little fascinated, until Mao Geng asked him to leave, Lao Peng was still a little reluctant to leave.

After getting on the carriage, Lao Peng said:

"Okay! Even the compressor is done, it's not easy!"

"This is prepared for the gas engine to inject compressed gas mixture. This two-stroke engine must be pressurized and injected fuel. The ball-stove-baked engine uses a plunger-type alcohol-type alcohol pump. Haha, I have prepared two sets of solutions for burning gas. The plunger pump can be used better, but the liquid is not compressible. There is no problem with the plunger pump spraying alcohol. It can be used for gas compression injection. So I made such a small and exquisite compressor just for compressing and injecting gas. Unfortunately, it is impossible to make a fully enclosed type, and leaks are inevitable. I can only control less leakage."

Injecting alcohol directly means copying the plunger-type fuel injection pump of later diesel engines, which is the reciprocating plunger pump controlled by cam spring. After knowing the principle, it is not difficult to copy.

But gas is a gas, which is different from incompressible liquid. If you have to use a plunger pump, the volume must be large enough, so Mao Geng thought of using a piston compressor.

Mao Geng regrets this piston compressor. He cannot seal the motor, crankshaft connecting rod mechanism and cylinder like the refrigerator compressor in later generations with a fully sealed iron shell. The advantages of this fully sealed design of the refrigerator compressor are very obvious. Even if the piston leaks, it cannot escape Freon. In this time and space, the conditions are still very limited. If you cannot achieve a full seal, just let the gas leak a little. Speaking of the coal fire in later generations, it is not that you have never smelled the smell of carbon monoxide, and it is not that nothing is wrong!

Mao Geng was very unhappy with the leak, but Lao Peng felt that the effect was already very good. Lao Peng was very curious:

"Without rubber, what seal is used?" Lao Peng almost said the word "rubber", but there was a coachman driving a carriage in front of him. Finally, Lao Peng reacted quickly and swallowed the word "rubber".

"Feel! The effect can only be said to be just right." In fact, later hydraulics will also use felt. Of course, anyway, seals such as felt cannot keep up with rubber seals.

Lao Peng admired Mao Geng's spirit of striving for excellence and said sincerely:

"Yes, not bad, I appreciate Chief Executive Mao's rigorous style. There is no need to be greedy for big things and fast. Take your time and lay the foundation firmer the better."

Speaking of greed and seeking speed, Mao Geng thought of Zhao Yuchun and then recalled Zhu Xi.

When he returned to Mao Geng's office, as soon as he entered the door, Lao Qiu, who had been staying on duty, asked:

"Look at that ball burning machine! Have you gone to Zhu Xi?"

Mao Geng thought, he really wanted to come with whatever he wanted, but this time he came, he was about Zhu Xi's head.

Lao Peng was still thinking about the ball burning machine and compressor just now, and exclaimed:

"The ball burning machine is good, it's really good! Chief Mao's work is very good!"

Lao Peng then realized something and asked in surprise

"Old Qiu, Zhu Xi, has he created a black technology that is more eye-catching than a ball burning machine?"

Lao Qiu has become accustomed to Lao Peng's reaction of half a beat slow, and a smile appeared on his face, saying:

"Old Peng, Zhu Xi's side is working hard now! Tell you, Mr. Zhu Xi is focusing on the focus now, one is an armored charcoal and the other is a charcoal gas generator, both hands are very hard! I can tell you responsibly that the prototype of the Zhu Xi version of the first generation of armored charcoal has been released. Of course, Chief Executive Mao and I, including most time travelers, do not think that that thing can be called an armored charcoal. Only Zhao Yuchun dares to fool Zhu Xi, claiming that it is an armored charcoal. Haha! Imagine that Mr. Zhu Xi will drive his iron charcoal to show off tomorrow. How nonsensical it is!"

"I'm quite curious about what kind of car it is."

"Anyway, you will see that this car is a thing dominated by Zhao Yuchun. It is steam-powered, and it is burned with gas, track-type, and outsourcing iron sheets. Well, if it is an armored car, it is not impossible to get over it at all. However, after you see it, you will definitely feel ridiculous. After I saw it, I couldn't help but think of the "earth blast furnace" and the "big steelmaking" era of the Great #Leap Forward. How bold people are, how much they are!"

After hearing what Lao Qiu said, Lao Peng glanced at Mao Geng and wanted to know how Mao Geng viewed this matter.

Mao Geng smiled strongly and had to say:

"It's not completely unreliable to say it's iron armor. At least the bow and arrow cannot do anything to it, and the cavalry of the Jin soldiers may not be able to get it. It depends on who to deal with. It's hard to say the word "tank" for the Japanese bean chariots, but it's still more than enough to deal with the Republican army. Zhu Xi was so eager to launch the iron armor chariot, probably to let the emperor arrange the Northern Expedition as soon as possible. If you understand this way, you won't be disgusted with Zhu Xi's rush to achieve success!"

Lao Peng had never seen the Zhu version of the armored chariot, so he had to repair it in his brain for a while. Habitually, Lao Peng remembered another thing about a charcoal gas generator. He was surprised that the best choice for large-scale production of gas should of course be to use coal to produce it. I believe that no one with normal brains would use charcoal to prepare gas.

"What's going on with that charcoal gas or something? Did Zhu Xi get it wrong?"

This time it was Mao Geng's answer:

"That's right! Lao Peng, in the 21st century later, North Korea was short of oil and was running charcoal cars on the road. In fact, it was a car equipped with a charcoal gas generator. It is said that the most powerful charcoal gas generator in later generations weighed less than 100 kilograms. After filling 200 kilograms of charcoal at a time, it could drive 100**10 kilometers, and the speed could reach more than 40 kilometers per hour. This is the information in a restored U disk by Wang Feng. At that time, China was blocked and gasoline was not available at all. In the absence of any way, it was the magical tool of the charcoal gas generator that prevented the car transportation from being shut down. It is said that the charcoal gas generator developed by China was the most advanced technology in the world at that time. None of them, the inventor seemed to be called Tang Tangzhong."

"It's Tang Zhongming." Lao Qiu remembered it clearly.

"Yes, it's him. Using charcoal as raw material should be considered that charcoal does not contain sulfur and does not require a complex filtration and sulfur removal device. This charcoal gas generator is not large in size. It is installed in a car and is now used. It does not require a gas tank. It is really amazing. It is impossible to accept it. Someone has calculated that a pound of charcoal can drive a car for one kilometer, which is much cheaper than using gasoline. We don't have gasoline available at all now, so we had to take the route of the Republic of China and spend a lot of effort to develop a charcoal gas generator. This matter was led by Gu Yongqiang, but Zhu Xi heard that this generator was so important, so he kept an eye on it very tightly and sometimes he did it himself. The old man's performance is really admirable!"

"Then, how about the charcoal gas generator?" Lao Peng almost hoped to see the legendary magical charcoal gas generator immediately.

"It can be used even if you make do, but gas production is still not so ideal, so you have to explore it." Mao Geng felt that it was quite difficult to catch up with the ox man Tang Zhongming.
