Just as Chen Liang, Xin Qiji, Lu Jiuyuan and Chen Liang were drinking together and Chen Liang was very excited, Peng Qin had just come out of the Duke's headquarters.

It took a little time to check Zhao Xing's body. When Zhao Xing fell asleep, the imperial physicians exchanged opinions solemnly. Everyone's views were quite consistent. His Majesty the Emperor seemed to be able to recover as before with just a little rest. As a so-called so-called person in the imperial medical care team, Peng Qinfang no longer needed to stand by on standby at this time. Peng Qinfang took a leave and left and walked straight to Mao Geng's Chief Executive.

It was already seven o'clock and it was already dark. However, there are street lights on the main street of the Special Administrative Region. All the street lights on this street were replaced with electric lights. The street lights were still quite bright on the street. Tonight's street lights were patrolling by the imperial guards of the Song Dynasty, which seemed a bit depressing, but overall, the appearance was quite good.

Peng Qinfang came to the Chief Executive leisurely, and Zhang Haisan greeted him and greeted him:

"Hello Mr. Peng!"

"Is Chief Executive Mao in the office?" Peng Qin said that Mao Geng should be in the office tonight. Today, the emperor arrived. According to the principle, Mao Geng should be on duty in the office.

"Yes, Mr. Qiu is here too."

When he entered the office, he met Mao Geng and Lao Qiu. Lao Qiu was also responsible for the reception, so he had to stay in the office with Mao Geng in case of any out-of-time needs of the emperor.

The two of them had just made a few simple dishes and ate them in the office. At this moment, when they saw Peng Qinfang coming, Lao Qiu asked:

"Haha, Lao Peng has a hard journey! Have you eaten? Haha, I should have a banquet to welcome you Lao Peng, but you are now a celebrity of the emperor and have the treatment of the royal family. I just asked wrongly, and I should be asking, I'll have a meal!"

"I haven't eaten yet! I'm here to get a free meal when I arrive at Chief Executive Mao."

Mao Geng asked Zhang Haisan to prepare the meal again. When there were three more people left, Peng Qinfang couldn't help but say:

"I'd better come back to the Special Administrative Region. It's really inappropriate for me to stay in Lin'an. I offended someone if I accidentally offended them. I originally went to public relations, but the result was good. Not only did the relationship not be adjusted well, but I messed up."

When Mao Geng saw Peng Qinfang like this, he thought that it was indeed a bit unreliable to stay in Lin'an with his emotional intelligence as Lao Peng, so he simply said openly:

"Old Peng, don't have any psychological burden, it's no big deal. Of course, it's best if you come back to the SAR. You have to know that there are many technical problems involving power and electronics waiting for you, the master, to solve them! However, now you are a destiny imperial physician, so it's hard to ask the emperor for you, right? Of course, we are also thinking about asking you. It seems that Zhu Xi has to come forward."

"Zhu Xi may not be more favorable than you, Chief Executive Mao!" Old Peng didn't understand why he wanted Zhu Xi to come forward.

Lao Qiu had no choice but to explain:

"Old Peng, there are some things that Chief Mao is not convenient for him to come forward, but Zhu Xi is different. Zhu Xi is a great scholar of his era, and the emperor also knows Zhu Xi's temper. Even if Zhu Xi said it wrong, the emperor would not take it to heart, but Chief Mao must not be careful when he speaks."

Lao Peng understood a little now. Well, first Mao Geng recommended himself to the emperor, and suddenly he wanted to bring people back. This will inevitably make the current emperor uncomfortable, and may even make the current emperor thunder angry. Humanity is to accompany the king as if he is a tiger. Mao Geng Lao Qiu did this, of course he could understand.

When Lao Qiu glanced at Lao Peng, he thought to himself that this guy is not the kind of person who can be easily understood, so he further said:

"Old Peng, tell you, since Zhu Xi became the director of the Academy of Geology, he has been doing his best. He is so competent that he can't say anything. We told him that you need to come back and preside over the electric ignition technology. Haha, that's what he told him. As long as you overcome this electric ignition technology, his armored chariot can be equipped with the most powerful power. If you don't come back, we can only use a ball-burning internal combustion engine. You also know that this ball-burning internal combustion engine is a transitional thing. This thing is okay for the transition, but it will eventually be eliminated. So, spark plug ignition is inevitable. If you want you to come back, the most urgent thing is to develop spark plug ignition technology. After hearing us, Zhu Xi will definitely go to the emperor to ask for someone. I guess Zhu Xi will do it, so there should be no big problem."

"Oh, that's good, that's good! I'm uncomfortable staying in Lin'an, so it's better to come back and do the skills!"

When he was about to come, Lao Peng frowned again and said:

"The technology of spark plug ignition is not too difficult. Two coils and one spark plug are really nothing. However, to develop a mature spark plug ignition technology, you can't hurry up. You will always need to work hard for a year."

At this time the food arrived, Mao Geng smiled and said:

"No, no hurry! Lao Peng, don't worry, it's serious to have a meal first."

Halfway through eating, Lao Peng suddenly remembered something and asked:

"As Laoqiu said just now, has the ball-burning internal combustion engine been successfully tested?"

Mao Geng looked at Lao Peng. The old man was stuck on his chin at this moment, and he looked curious, so he smiled and said:

"That's right, if you want to see it, you'll see our first ball burning internal combustion engine in a while."

"Good things, good things! You have to see, of course."

After a few bites of rice, Lao Peng asked to go and see the treasure machine immediately. Lao Qiu shook his head and thought to himself that it was already half past eight, and it was a curfew now. It was a bit inappropriate to go and see it now.

Lao Qiu was about to stop him, but Mao Geng waved his hand and said:

"It's okay, go and have a look!"

In fact, even if there is a curfew, no one will stop Mao Geng.

When I arrived at the site of the burning ball internal combustion engine test, the noise of the test machine seemed particularly high on a quiet night, or it was particularly unbearable. This is an inherent problem of the burning ball internal combustion engine. In short, the noise is exaggerated.

Seeing Mao Geng, Tan Xiaochun, who was on duty, immediately reported:

"It's normal to run. I just stopped the machine once, because the alcohol injection volume was lowered in the middle, and the injection volume might be too low, so the machine turned off. After restarting, it's normal until now." Due to the high noise, Tan Xiaochun almost put it on Mao Geng's ear when he reported it.

Mao Geng nodded, not commenting.

Mao Geng knew that this was a problem with the burning ball internal combustion engine. This kind of internal combustion engine needs to keep the ignition high-temperature iron ball in the high temperature state. Once the accelerator is adjusted too small and the fuel is injected too little, it may not be maintained at the continuous high temperature state of the ignition iron ball. The consequence of the continuous cooling of the iron ball is that even if fuel is injected, it will not catch fire, so the entire engine will be shut down. In this case, you can only use the blowtorch to reheat the iron ball and then restart the engine.

Maintaining the continuous high temperature of the iron ball is a waste of energy. In other words, there are many unscientific and imperfect parts of this type of ball burning internal combustion engine. However, by the way, this single-cylinder ball burning engine does not pay much attention to processing accuracy, and can be used to make do with cast iron parts. It is the kind of internal combustion engine with the lowest threshold. Because the threshold is the lowest, I believe it is the favorite of all time travelers. It is nothing else, and it is easy to get started.

Not only does the ball burner have a low threshold, it also has advantages such as this.

For example, in terms of thermal efficiency, it can easily roll the steam engine. Don’t underestimate this ball-burning internal combustion engine. No matter how bad it is, it is an internal combustion engine after all. It is amazing if the thermal efficiency of the steam engine reaches 8%, and the thermal efficiency of the ball-burning internal combustion engine can easily reach more than 12%.

In addition, since it is an internal combustion engine, it can be made smaller in volume and weight, which is not comparable to the steam engine.

The burning ball internal combustion engine in front of me is not large in size, which makes Lao Peng, who has seen too many large skeleton steam engines of this era, illuminate his eyes.

However, when you get close, not only does the noise be amazing, but you can also smell a strong smell of alcohol. By the way, fuel cannot be completely burned in the cylinder, which is also a common problem with this kind of internal combustion engine.

Lao Peng stared at the prototype and looked left and right. At this moment, the thing was spinning very happily, and Lao Peng was also quite encouraged.

Old Peng moved to Mao Geng and asked:

"I'm using alcohol as fuel!" It's obvious that Lao Peng didn't hear anything Tan Xiaochun said clearly just now.

Lao Peng's question was too gentle, and the noise in the field was too exaggerated, so Mao Geng didn't understand what Lao Peng was saying.

Mao Geng had to pull Lao Peng to the room aside and close the door. The noise was not that loud. This time, Lao Peng repeated it loudly, and Mao Geng replied:

"Yes, this prototype now uses alcohol as fuel, but alcohol as fuel has no practical value, and the next prototype will use gas."

Lao Peng nodded.

In fact, the development of internal combustion engines has been discussed many times before and included in the three-year plan. As for the technical route, of course, it is simple and then complex, first based on existing conditions, make full use of existing technologies and resources, and then steadily improve on this basis. Therefore, it is not surprising that the first step is to choose a ball-type internal combustion engine, and in terms of fuel selection, the first choice is gas that is easiest to prepare under today's conditions.

In real history, the first practical internal combustion engine was a gas engine, and the four-stroke internal combustion engine invented by Otto in 1876 was also a gas engine.

The large-scale application of gas in real history dates back to the United Kingdom in 1815. In 1815, the United Kingdom had 26 miles of gas pipelines alone. In this year, the commercialization of gas in Britain achieved remarkable achievements. However, in 1815, commercial gas was not used for cooking, nor for hot water. From 1815 to 1836, the only purpose of commercial gas was to be used for lighting. It was not until the advent of Edison's bamboo charcoal wire electric lamps in 1880 that gas lighting gradually declined, but gas lighting continued for at least thirty years after 1880.

In 1864, the Celestial Shanghai also began to enter the era of gas lighting due to the British. In March 1864, the first gas company in Shanghai, "Daying Autonomous Fire House", opened. On December 18, 1865, the first gas lamp of the Daying Autonomous Fire House was officially lit up on Nanjing Road. Gas lamps were originally mainly used in foreign shops and street lights, but later they were used in storehouses, shops, teahouses, theaters and homes. The famous name of "Sleepless City" in Shanghai began around the end of the 1860s. By the 1870s, Shanghai people named the "Ten Scenery Scenes in the Concession", one of which was the "Night Market Lighting".

With the emergence of electric lights, gas lamps eventually became yesterday's yellow flowers. However, although gas, as a "boot fire", was defeated by electric lights in lighting, it showed great advantages in cooking and heating. Since the first gas stove manufacturer in Ampton, England opened in 1836, to 1852, gas stoves that were close to modern gas stoves were released, and after that, gas made a fortune in the kitchen market, reaching its peak in the 1900s, until the 21st century, under the squeeze of liquefied petroleum gas and natural gas, the market share of gas was weak, but it still stubbornly occupied a considerable market.

In the 12th century, it seems that oil mining is not reliable for the time being. No one of the travelers has ever been exposed to oil exploration and does not know how to explore or how to mine it. Yes, China also has oil "self-flowing wells". Self-flowing wells are open-pit minerals. Locals in Yan'an can find oil in the ditch. However, these self-flowing wells with oil flowing oil are all in northern Shaanxi. At this time, northern Shaanxi was not under the jurisdiction of the Song Dynasty or under the jurisdiction of the Jin people. Anyway, they have no connection with the Song Dynasty after the southward transition. It is still possible to purchase some "sulphur oil" from the smuggling channels, but it is completely a dream to purchase such strategic substances that can be used to defend the city from the Xixia or the Jin people on a large scale.

Therefore, I had to stop thinking about oil for the time being.

However, as long as there is enough coal, the technical threshold for preparing gas is lower than that of hot ball internal combustion engines. Therefore, gas is the only correct choice for internal combustion engine fuel, and it is widely used worldwide.

If there are time travelers, it means that gas is a necessary time travel killer for home travel and killing people and setting fires. If you travel to ancient times and don’t develop it, it will be a waste of time travel.

What’s ridiculous is that at first no one remembered the magical fuel of gas, but later it was mentioned by Tang Kai, a native of Shanghai. Half a year ago, Tang Kai’s letter was delivered to Mao Geng. As soon as everyone planned, they immediately included gas in a key development project. At the same time, the ball-burning internal combustion engine also entered the development in advance.

Now, the steam engine era and the internal combustion engine era are about to arrive at the same time.
