Chapter 60 Target Kiln Gang Engage in Diesel Engines

Li Zicheng endured his grief and sent someone to send Hao Shaoqi's body back to Xi'an, just as Yuan Zongdi and Liu Tichun arrived in a simple manner. Yuan Zongdi and Liu Tichun are collectively known as the Two Tigers, and they are almost as famous as Li Guo. Li Guo is known as one tiger, but they are called two tigers. However, Yuan Zongdi is the general of the right battalion of the Dashun army, and Liu Tichun is the general of the right battalion and the right standard Guoyi. After Li Zicheng became emperor, Yuan Zongdi was named "Mianhou", and Liu Tichun was named "Guangshan Bo". The two of them are actually a big level apart.

When Li Zicheng saw that they had arrived, he was polite and asked Song Xiance to introduce the war with the Yaogang people during this time.

The two of them couldn't accept that the Dashun army would fight to this extent. Yuan Zongdi said: "King Chuang, let's go to the front line to see the situation." I don't believe in the three-headed and six-armed people born in the kiln. ”

Li Zicheng said: "What I'm most worried about is that you are not convinced, and you will suffer a big loss." Now General Quan's injuries are not healed, and the flag is just gone. There is no one on the front line, you must go to the front line immediately. However, it is not allowed to take the initiative without an order. ”

As he was talking, Liu Zongmin came in with a curtain on the door, probably he also heard what Li Zicheng said, and said, "Master! I'd better go back to the front. I am familiar with my soldiers, and I am familiar with what lies ahead. Don't worry, before I think of a countermeasure, I just won't fight. ”

At this time, Yuan Zongdi and Liu Tichun stood up and saluted Liu Zongmin, "Hello General Quan!" ”

Liu Zongmin said: "You came just in time, just follow me to the front to have a look and give Lao Tzu an idea." ”

Li Zicheng said: "Zong Min, your health is not good, let's take care of it!" ”

Liu Zongmin said: "Master, it is better to recuperate your wounds on the battlefield of the former enemy than to recuperate your wounds there. I'm fine, don't worry. ”

Niu Jinxing said: "If General Quan is in good health, I think it would be best for General Quan to go back." But don't strike yet. ”

At this time, it was reported that Gao Yigong was coming, and Li Zicheng said, "Let me come in!" ”

This Gao Yigong is Li Zicheng's brother-in-law and a native of Mizhi, Shaanxi. This person is resourceful and decisive, and he is also Li Zicheng's right-hand man, serving as the mighty general of Xiangyang Weizuo.

After greeting for a while, Li Zicheng said: "Several of you are here today, let's also discuss, what should we do next?" ”

Li Zicheng's words made Niu Jinxing and Song Xiance very uncomfortable, because the major events of the Dashun Army's actions did not need these lower-level officers to participate in the discussion, but should be discussed with them by Li Zicheng and passed the order to them. It seems that although Li Zicheng didn't say it, he was already a little dissatisfied with the two of them not being able to come up with a decent idea at this time.

Yuan Zongdi, Liu Tichun, and Gao Yigong have all been cleaning up the remnants of the Ming Dynasty in the area of Jinzhong and Jinnan, and they did not participate in the battle of Xiurong and Fort, they don't know much about the actual situation, but they have not been convinced in their hearts, but seeing that Liu Zongmin and Hao Shaoqi were defeated, they didn't dare to squeak.

Liu Zongmin said: "Master, if we can't think of a way to deal with the artillery of the Yaogang people, I don't think Xiurong City and that fort will fight first, and we won't be able to attack no matter how many people die." So far, we haven't fought against the Yaogang people, but tens of thousands of people have died, and we can't continue to fight like this. Liu Zongmin didn't care about Niu Jinxing and Song Xiance's faces, and continued: "The military advisor also thinks of a way for us, right?" ”

Song Xiance said: "What General Quan said is true. Until now, we have not been able to deal with their artillery. Their cannons were not only accurate, but also powerful. What's more, their cannons are very sophisticated. Our superiority is the valiant and good fighting of the cavalry and infantry, but they do not give us a chance to fight; We also have the advantage that we have hundreds of thousands of people, which is the advantage of being outnumbered. But no matter how many people there are, they can't show it in front of a small city like Xiurong. What's more, these two places are tall city walls, and they throw them down from a high place with the kind of ** that doesn't want silver, and we can't defend it, only to be bombed. ”

"Come on, Strategist! Tell me what to do! Liu Zongmin was impatient.

Li Zicheng shouted: "Zong Min must not be rude! Let the military advisor speak slowly. ”

Song Xiance was not annoyed, and said: "I think we might as well attack the kiln directly." Now our army is slowly gathered. There is a large area to the west and south of the kiln that can be attacked, and if we use fireworks, the wind will be just right to cover us, and their cannons will lose their accuracy, and our cannons will be able to play a role in not being beaten. What's more, their kiln workers were so arrogant that they didn't even build a city wall, and built a total of several barbed wire and trenches. But I can use our forces in full. ”

Li Zicheng said: "It seems that we have no choice but to do it according to the method of the military division. However, we have dealt with Zhang Zhimu of Yaogang for so many years, Zhang Zhimu of Yaogang is a very scheming person, they dare not to build the city wall, they must have their ideas. ”

Niu Jinxing said: "Did they dare to build the city wall before we called? If they build the city wall, Emperor Chongzhen still doesn't think that he wants to rebel, in that case, Emperor Chongzhen will get rid of him without us calling. Ha ha! ”

Li Zicheng also laughed: "Haha! What the prime minister said makes sense. I will personally command this attack on Yaogang, and tomorrow the old battalion will be mentioned to Yaogang. When we get to Yaogang, we have to study how to fight this battle? All the armies must assemble at the kiln gang, and you should worry about this matter. ”

Song Xiance said: "Your Majesty, you don't have to worry about this." I'll arrange it. ”

The Dashun army did not attack, but their movement was quickly notified to the command center by Li Jing.

As soon as Zhang Zhimu arrived at the command center in the morning, Ouyang He said to him and Chen Yufeng: "The news sent back by Li Jing shows that Li Zicheng is going to deal with us according to our ideas. The show is about to begin. ”

Zhang Zhimu said: "I'm not worried about the defense of our kiln, but in Xiurong and the fort, we killed tens of thousands of people from the Dashun army. Years of war and drought have been in a row, and the population is already small, and these people are all in the prime of life, but it's a pity! ”

Chen Yufeng said: "Zhimu, what Mr. Ouyang and I are most afraid of is your soft-heartedness. At this time, you must not be soft-hearted, otherwise it will affect the decision made. This is a war, not a child's play, the Dashun army has come up, and there will be no softness. There are many examples of Li Zicheng slaughtering cities. ”

Ouyang He said: "We beat Li Zicheng once, it seems that more people died, but this is to die less and more people in the future." ”

Zhang Zhimu smiled and said, "Don't worry, after this period of time, I have been able to accept the bloody reality in front of me. I won't be a little soft-hearted when the fight starts. I just sighed, if this man didn't die, it would be nice if we set up a reclamation team. ”

"Let's talk about it after the battle, I see that Mr. Lu and Mr. Lu are more interested in this matter, and they have already selected several places to be cultivated." Ouyang He said.

Zhang Zhimu said: "Okay, I'm a little worried that our soldiers have been in the trenches for too long and will be a little slack. ”

Ouyang He said: "Don't worry, the actors of the troupe organized by Liu Banzhu, when they are fine, they will go to the front to comfort the soldiers." Without fighting, they haven't had a chance to see Little Ruby yet. Ha ha! And your Xiaoqing, who also organized the students to go to the front to sing and perform for the soldiers, and the food in the front was also good. Morale is high. ”

At this time, a staff officer asked Zhang Zhimu to answer the phone. It turned out that Li Yunhe called here. As soon as Zhang Zhimu answered the phone, Li Yunhe shouted on the phone: "Hey! Didn't we say okay, you're going to give a lecture today? They're all waiting. ”

Zhang Zhimu patted his head and said, "Oops! Blame me. Let me forget, I'm here early in the morning, I'll go right away. Don't worry! ”

Chen Yufeng said beside him: "It must be Yunhe, a little rabbit cub, and he dares to talk to Zhimu in the entire kiln." One day I cleaned him up. ”

Ouyang He said: "Yunhe has made a great contribution to our kiln gang!" That's why Mr. Zhang spoiled him so much. ”

Zhang Zhimu said: "Uncle Chen, you didn't expect that the young man who carried a large amount with you would become such a person today!" ”

Uncle Chen said very smugly: "That's! This kid, I think it's much better than him. It seems that he chose the right person to do this. But if he had been asked to lead the troops, he would have been a good player, he would have been a man with a brain. ”

Zhang Zhimu originally wanted to give a lecture to those people who were engaged in locomotive boilers, but he didn't expect that more than 150 people would come to listen to the lecture. When asked Li Yunhe, Li Yunhe said: "Today, all of our people who used to work in steam engines have come to attend the class. None of them want to be left behind. ”

Zhang Zhimu said: "Okay! It's good to listen to them all. There is one more thing I want to ask you, did you say that you got a high-precision rifle for Sun Liang and them? ”

"I've gotten five for them, and I've got two of them with guns. Otherwise, they wouldn't be able to see any scopes. When they try it out, no problem, I'll produce some high-precision rifles for them. Li Yunhe said.

Zhang Zhimu said: "I have another idea. Can you make a semi-automatic rifle or a manual rifle with a scope with a machine gun barrel that is a little longer? In this way, we strive to be able to shoot with an accuracy of 800 meters. The accuracy of this gun in all aspects must be as high as possible, and mass production is not required, but the accuracy must be high. The parts of the gun should not be loosened in any way because of the recoil, the stability of the gun should be very high, and the bullets should be specially made. The accuracy and quality of the charge must be strictly guaranteed. However, if you don't have special bullets, you can also use regular machine gun bullets. What do you think? ”

Li Yunhe said: "Okay! It just so happened that their machine guns were almost done. I'll go back and talk to them about my thoughts. Let's give a lecture today! ”

Zhang Zhimu looked at the more than 150 people below, and he was very emotional. Most of them participated in the design and production of several models of steam engines. Looking at their eyes, it revealed more confidence. But they know that the lessons they are taught are often a leap forward in their thinking. So when they heard the news that Zhang Zhimu was going to give a lecture, they immediately put down what they were doing and listened to the lecture.

Zhang Zhimu said: "Today I want to talk to you about the basic principles of gasoline engines and diesel engines. But before I get to that, I want to answer one of your questions, that is, what is gasoline and diesel. ”

The people who listened to the lecture smiled heartily, they really wanted to ask this question.

Zhang Zhimu continued: "Many of you know that when we were making coke in the smelter, we left a lot of coal tar, and some people said that those things were too difficult to preserve and took up space. I said it was all treasures, and some people still didn't believe it. So I tell you today that those coal tars are not only treasures, but those things will not be enough for us in the future, and we will have to spend a lot of effort in the future to find fierce fire oil to replace them. Because coal tar contains a lot of treasures. This includes gasoline and diesel. Later, we can use distillation to extract gasoline and diesel from coal tar. ”

After speaking, Zhang Zhimu wrote on the blackboard:

Gasoline 30--------74 degrees

Kerosene 74--------120 degrees

Diesel 120------180 degrees

Oil 180------250 degrees

Finally, there is asphalt

Then Zhang Zhimu said: "According to this temperature, we can divide coal tar into these components through fractionation. Among them, gasoline is what we want to use in gasoline engines, and diesel is used in diesel engines. We can use that kerosene as fuel, but it is not good to use it for lighting a lamp, because it emits the least amount of smoke when it is burned, and if we use it for our lanterns, we don't have to constantly wipe the blackened glass. And this oil is more useful. Now you have all come into contact with a lot of machinery and equipment, and many of you have also participated in the manufacture of lathes. I think you must have encountered the problem that when the speed of the gear transmission is very high, it will not work, because it will heat up very quickly. Then when we have the oil, we can immerse the entire gearbox in the oil, because the oil is the best lubricating oil, and it can dissipate heat. Therefore, it is not too much to say that engine oil will bring a promoting effect to our machinery industry. After purification, the engine oil can also be used as transformer oil and hydraulic oil, which is also what we need immediately. In addition, gasoline also has a good use, it is a good solvent to remove oil stains, etc., and the mechanical parts are not clean in the future, you can also use gasoline to rinse. Okay, that's all for now. The fractionation of these oils will be a big industry in the future, and those who are interested can pay attention to this matter earlier. Next, I will first explain to you the basic principles of diesel engines. ”

Zhang Zhimu paused at this point. He knew that Fang had explained it simply, and had already answered many of their previous questions. Sure enough, there was a buzz below, and they seemed to have answers to a lot of unresolved things. What they didn't expect was that coal tar could be so useful, no wonder Zhang Zhimu said that they were all treasures before, but this is not a treasure.

Regardless of the following discussions, Zhang Zhimu drew the four working states of a diesel engine cylinder on the blackboard.

Zhang Zhimu said: "Our diesel engines, like steam engines, also have cylinders and pistons. This diesel engine has four working states, we call four strokes. First of all, when the piston moves outward, it sucks air from the inlet to the cylinder, which is called the suction stroke; Then when moving back, the compressed air, we call it the compression stroke, at this time the pressure of the air can reach a very high level, and the temperature will also be very high; The third step is to inject diesel fuel into this high-temperature and high-pressure air through a high-pressure oil pump, and the atomized diesel is quickly mixed with high-temperature and high-pressure air, and then burns to produce an explosion that pushes the piston outward, and when it reaches the limit, it moves back under the action of the outside balance wheel, and then the exhaust port is opened to discharge the exhaust gas after combustion. When the piston moves outward again, go back and inhale again. In this way, the diesel engine will move back and forth. The ignition method of diesel engine is called compression ignition.

You've all worked on steam engines, so I don't need to tell you how to turn the reciprocating motion of the piston into the power you need. What I want to say is that such a diesel engine has a lot of power, a small size, and a light weight. They can be used better and more conveniently by us, and the first thing that should be considered is, Li Yunhe, your four-wheeled carriage, what will happen if you drive the rear wheels of your carriage with this kind of power, everyone think about it. What would happen if we put it on a small boat, you guys also think about it. ”

Zhang Zhimu's words were like throwing a stone in the water, and the people below immediately talked about it.

Zhang Zhimu said: "Everyone, please be quiet. I would now like to introduce you to the principle of gasoline engine. In fact, the gasoline engine is the same as the diesel engine, with four strokes. However, since gasoline has a higher ignition point than diesel, we need to use an electric spark to ignite it. And the gasoline engine does not use the high-pressure oil pump to inject fuel, but at the same time as the cylinder sucks the gasoline and air mixture is sucked into the cylinder at the same time, the mixed gas is formed in the cylinder, when the cylinder compression stroke is completed, the electric spark ignition ignites the mixed gas, and the gas explodes to push the piston outward. This is the difference in principle between the two engines. ”

Zhang Zhimu didn't talk much about today's class, and he could spend a lot of time discussing problems with everyone. Naturally, everyone focused on what would happen if a diesel or gasoline engine was used in a horse-drawn carriage. Zhang Zhimu said: "When we talk about the use of diesel engines or gasoline engines in horse-drawn carriages, horse-drawn carriages are no longer called horse-drawn carriages. Because you don't have to pull a horse. Let's call it a car. At that time, we could move one wheel by hand to control the direction of the two wheels in front of us. Use a gasoline or diesel engine to push the two wheels behind you forward, and the car will run faster than the horse. In the future, wherever each of us goes, we will just drive a car by ourselves, and we don't need grooms and horses, as long as we have petrol and diesel. I used to say that coal tar is a good thing, right? ”

Everyone said, "That's right! ”

Zhang Zhimu said: "However, if we want to get to the point I said, we all need to make a lot of efforts. You first come up with a diesel engine prototype, and then it's easy to talk about later. It took us a lot of time from getting the first steam engine to running around now. But this time, everyone has the foundation to engage in steam engines, I think both gasoline engines and diesel engines will be developed soon, everyone work hard! ”
