Just when Chen Liang was drinking with Xin Qiji and 6 Jiuyuan, and Chen Liang was blowing very high, Peng Qinfang had just come out of Guogong.

Delayed a little time for Zhao Yan to check his body, and when Zhao Yan fell asleep, the imperial doctors solemnly exchanged opinions, and everyone's views were more consistent, His Majesty the Emperor seemed to only need a little rest to recover as before, as a soy sauce person in the Taiyi health care team, Peng Qinfang no longer needed to be on the side at this time, Peng Qinfang took leave and left, and went straight to Mao Geng's special mansion.

At this time, it was already past seven o'clock, and the sky was already dark, but now the main street of the Special Administrative Region was lit by street lights, and all the street lamps on this street were replaced with electric lights. Tonight's street looks a little depressing because of the Great Song Dynasty Forbidden Army patrolling, but overall, the look and feel is quite good.

Peng Qinfang came to the Special Mansion, and Zhang Haisan greeted him:

"Hello Mr. Peng!"

"Maudt is in the office, right?" Peng Qinfang expected that Mao Geng should be in the office tonight, and the emperor arrived today, so it stands to reason that Mao Geng should be on duty in the office.

"Yes, Mr. Qiu is also there."

When I entered the office, I saw Mao Geng and Lao Qiu. Lao Qiu is also responsible for the reception, so he wants to stay in the office with Mao Geng, in case the emperor has any unexpected needs.

The two of them just let someone make a few simple dishes and eat them in the office. As soon as he saw Peng Qinfang coming over at this time, Lao Qiu asked:

"Lao Peng's journey has been hard! Have you eaten it? Hehe, there should have been a banquet for your old Peng to pick up the wind and wash the dust, but you are now the emperor's celebrity, and you have royal treatment. I didn't ask the right question just now, what I should have asked was, let's eat! ”

"I haven't eaten yet! When I came to Maote, I came to eat. ”

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

"I'd better go back to the Special Administrative Region, it's really inappropriate for me to stay in Lin'an, and I'll offend people by accident. Originally, I went to engage in public relations, but it turned out to be good, not only did the relationship not adjust well, but I made it worse. ”

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

"Lao Peng, you don't have any psychological burden, it's not a big deal. It's best if you come back to the SAR. You must know that there are many technical problems involving power electronics, which are waiting for you as a master to solve! However, no matter what you say now, you are also the imperial doctor of the Qin order, and we can't open our mouths to ask the emperor for you! Of course, we are also thinking about recruitment, and it seems that we have to ask Zhu Xi to come forward in this matter. ”

"Zhu Xi doesn't necessarily have a bigger face than you!" Lao Peng didn't understand why he asked Zhu Xi to come forward.

Lao Qiu had no choice but to explain:

"Lao Peng, there are some things, Mao Te is inconvenient to come forward, but Zhu Xi is different. Zhu Xi is a great Confucian of this era, and the emperor also knows Zhu Xi's temper. Even if Zhu Xi said something wrong, the emperor would not take it to heart, but Mao Te couldn't be careless when he spoke. ”

Lao Peng understood a little at this time, well, first Mao Geng recommended himself to the emperor, and suddenly wanted people back, which will inevitably make today's saints feel uncomfortable, and may even make today's saints thunder and anger, humanity is like a companion to the tiger, Mao Geng Laoqiu did this, of course he can understand.

Lao Qiu glanced at Lao Peng, and said in his heart that this old man is not the kind of person who can understand everything, so he further said:

"Lao Peng, let me tell you, since Zhu Xi became the dean of the Gewu Academy, people have always done their best, and they are so competent that they have nothing to say, and they can't admire it. We told him that we needed to let you come back to preside over the electric ignition technology, hehe, the reason is that as long as you conquer this electric ignition technology, his ironclad chariot can be equipped with the most powerful power. If you don't come back, we can only use the burnt ball internal combustion engine, and you also know that this burning ball internal combustion engine is also a transitional thing, and this thing is okay for a while, but it will be eliminated in the end. So, spark plug ignition is imperative, and if you want to come back, the top priority is to get the spark plug ignition technology. Zhu Xi listened to us, he will definitely go to the emperor to ask for someone, I estimate that Zhu Xi is out of the horse, it should not be a big problem. ”

"Oh, that's good, that's good! I'm uncomfortable staying in Lin'an, so it's better to come back and engage in technology! ”

When it was over, Lao Peng frowned again and said:

"This spark plug ignition, the technology is not too difficult, two coils, a spark plug, there is really nothing, however, to develop a set of mature spark plug ignition technology, the time can not be rushed, a year of hard work is always required."

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

"No hurry, no hurry! Lao Peng, you can rest assured, it is serious to eat first. ”

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

"According to what Lao Qiu just said, has the burning-ball internal combustion engine been successfully trial-produced?"

Mao Geng looked at Lao Peng, this old man had rice sticking to his chin at the moment, and he was eager to learn, so he smiled and said:

"Well, if you want to see it, you'll be able to see our first burning-ball internal combustion engine in a moment."

"Good thing, good thing! It sees, of course. ”

After Lao Peng finished taking a few bites of rice in three times, he asked to go to see the baby machine immediately. Lao Qiu shook his head, and said in his heart that it was half past eight, and it was curfew at this time, so it was a little inappropriate to go and see it now.

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

"It's okay, let's go check it out!"

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

Coming to the site of the test of the burned-ball internal combustion engine, the noise of the test machine is particularly high in the quiet night, or it is particularly unbearable, which is the inherent problem of the burned-ball internal combustion engine, in short, the noise is very exaggerated.

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

"It's running pretty well. It was only stopped once, because the amount of alcohol injection was lowered in the middle, maybe the injection volume was too low, and the machine went out. After restarting, it has been working fine until now. Due to the high noise, Tan Xiaochun almost put it on Mao Geng's ears when he reported.

Mao Geng nodded, noncommittal.

Mao Geng knows that this is the problem of the burning ball type internal combustion engine, this internal combustion engine needs to keep the ignition high temperature iron ball inside has been in a high temperature state, once the throttle is adjusted too small, the injected fuel is too little, it may not be able to maintain the continuous high temperature state of the ignition iron ball, the consequence of the continuous cooling of the iron ball, that is, even if the fuel is injected, it can not ignite, so the whole motor is extinguished. In this case, the only way to reheat the ball with a blowtorch is to restart the engine.

Maintaining the continuous high temperature of the iron ball is itself a waste of energy. In other words, there are really a lot of unscientific and imperfect places about this kind of burning-ball internal combustion engine. However, having said that, this single-cylinder burning ball type motor is not very particular about machining accuracy, and it can be made with iron castings, which is a kind of internal combustion engine with the lowest threshold.

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

In terms of thermal efficiency, for example, it can easily roll a steam engine. Don't underestimate this burnt-ball internal combustion engine, no matter how bad it is, it is an internal combustion engine after all, the thermal efficiency of the steam engine can reach 8%, and the thermal efficiency of the burned-ball internal combustion engine can easily reach more than 12%.

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

The volume of the burning-ball internal combustion engine in front of him is not large, which makes Lao Peng, who has seen a lot of large skeleton steam engines in this era, shine.

However, when you get closer, not only is the noise amazing, but you can also smell a strong smell of alcohol. In other words, the fuel cannot be completely burned in the cylinder, which is also a common problem of this internal combustion engine.

Lao Peng stared at the prototype left and right, at this moment this thing turned very happily, and Lao Peng was also quite encouraged in his heart.

Lao Peng moved in front of Mao Geng and asked:

"Alcohol is used as fuel!" Obviously, Lao Peng didn't hear what Tan Xiaochun said at all just now.

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

Mao Geng had no choice but to pull Lao Peng to the side of the room, close the door, the noise was not so loud, this time Lao Peng repeated loudly, Mao Geng replied:

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

Lao Peng nodded.

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

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

The large-scale use of coal gas in real history can be traced back to 1815 in England. In 1815, 26 miles of gas pipelines were laid in Britain alone, and in this year, the commercialization of gas in Britain was a remarkable achievement. However, in 1815 commercial gas was not used for cooking, nor for hot water, and from 1815 to 1836 the only use of commercial gas was for lighting. It wasn't until the advent of Edison's bamboo charcoal filament lamp in 188o that gas lighting declined, but it continued for at least thirty years after 188o.

In 1864, Shanghai of the Celestial Empire began to enter the era of gas lighting because of the British. In March 1864, Shanghai's first gas company, the "Daying Fire House", was opened, and on December 18, 1865, the first gas lamp was officially lit on Nanjing Road. At first, gas lamps were mainly used for foreign shops and street lamps, and later they were used in shops, shops, teahouses, theaters and homes. The reputation of Shanghai as the "city that never sleeps" is about the end of the sixties of the 19th century. In the 70s of the 19th century, Shanghainese rated the "Ten Scenic Spots of the Concession", one of which was the "Night Market Lighting Lamp".

With the advent of electric light, gas lighting has finally become a thing of the past. However, although gas as a "tap fire" lost out to electric light in lighting, it showed great advantages in cooking and heating. Since the opening of the first gas stove production plant in Ampton, England in 1836, to 1852, the gas stove close to the modern gas stove came out, after that, gas in the kitchen market to hit a day, in the first decade reached its peak, until the 21st century, under the squeeze of liquefied petroleum gas and natural gas, the market share of gas is declining, but still tenaciously occupies a considerable market.

In the twelfth century, oil extraction seemed to be unreliable for the time being, and none of the traversers had ever been exposed to oil exploration, and they did not know how to explore or exploit it. Yes, China also has oil "artesian wells", artesian wells are open-pit deposits, the locals of Yan'an can find oil in the ditch, but these artesian wells flowing oil are in northern Shaanxi, at this time northern Shaanxi does not belong to the jurisdiction of the Great Song Dynasty, and I don't know whether it is under the jurisdiction of the Western Xia or the Jin people, anyway, it is not in line with the Great Song Dynasty after the southern crossing. It is still possible to buy a little "hot oil" from the "artesian well" from the smuggling channel, but it is completely foolish to purchase this strategic material that can be used to defend the city from the Western Xia or Jin people on a large scale.

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

However, as long as there is a sufficient amount of coal, the technical threshold for preparing gas is lower than that of a hot-bulb internal combustion engine, so gas is the only correct choice for internal combustion engine fuel, and it is a global kill.

Some traversers said that gas is a necessary cross-cutting weapon for home travel to kill people and set fires, and if you travel to ancient times and don't turn on the gas, it will be in vain.

What's ridiculous is that about such a magical fuel as gas, everyone didn't think about it at first, but later it was Tang Kai, a Shanghainese who mentioned it. Half a year ago, Tang Kai's letter was sent to Mao Geng, and everyone immediately included gas in the key exhibition projects, and at the same time, the burning-ball internal combustion engine also entered the development ahead of schedule.

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