Among the five people who entered in the third group, the self-introduction of the last person made Zhang Tie focus on him.
He was a young man, less than thirty years old, gentle and elegant. More importantly, Zhang Tie felt that this man looked familiar inexplicably.
"Sun Qiming, the Hongyuan Merchant Group of Xuantian City, has met the real Zhulong!"
Surname Sun
Zhang Tie suddenly understood why he thought this person looked familiar, because just now, the face shape of the child Lu Shasha was carrying was 70% or 80% similar to the Sun Qiming in front of him. Taking a closer look, Zhang Tie It was immediately confirmed that this Sun Qiming was the husband of his junior sister Lu Shasha.
What does it mean to write a book without coincidence? This is it! If you really want to talk about it, Sun Qiming should follow Lu Shasha and call him senior brother.
After looking at Sun Qiming for a few times, Zhang Tie's tone suddenly softened, "Your Sun family is also good at manufacturing machinery and equipment?"
"To be honest, I don't dare to say that I am good at it. Taixia is the best among humans in the field of machine manufacturing. There are people who are hiding dragons and crouching tigers in all states. Compared with Taixia's top big business groups and families in the field of machine manufacturing, we There is still a certain gap, but our Sun family has been in the machine manufacturing industry for several generations and is well aware of the various ways in the field of machine manufacturing. The family’s main machine products are several different types of pot camel machines, and also There are several types of small steam machine tools and some steam city defense equipment. Hongyuan brand machine products are well-known in Youzhou and the entire Northeast Governor's Office, and are also loved by many old customers." After hearing Zhang Tie's inquiry, Sun Qiming He is even more modest and cautious, and his words are flawless. It not only stated the Sun family's own advantages, but also did not offend the other families in the flower hall.
"You said that Sun Jiazhen has been involved in the machine manufacturing industry for many years. Then let me test you. What is the difference between this steam-powered machinery and the internal combustion engine machinery that was popular before the catastrophe?"
Sun Qiming remains humble. Because Zhang Tie's question can't be said to be a test at all. As long as people in this industry, even those who have just joined the industry, everyone knows it. However, Zhulong Zhenren said it was a test, and no one sitting here knew it. Dare to say that Master Zhulong’s question is naive, so he can only answer it seriously. It can't reveal any other peculiar colors.
"Machines powered by internal combustion engines before the Cataclysm have many advantages compared to steam-powered machinery. The most obvious ones are small size, light weight, high power, rapid ignition, and wide application. This is why humans eliminated steam before the Cataclysm. The reason why we choose internal combustion engine power instead of power.”
Zhang Tie nodded. "In your opinion, if you were given an internal combustion engine now, where do you think it would be most useful?"
"The technology of internal combustion engines has been completely mature more than a thousand years ago, even with the current level of machine manufacturing. It is not difficult to make a mature internal combustion engine. The difficulty is to make it if there is no fuel to drive it. That kind of Internal combustion engines are also decorations. And because they have lost the possibility of continuing to drive internal combustion engines, in this era, in order to pursue the high energy and efficiency characteristics of internal combustion engines, people have developed external combustion engines between steam engines and internal combustion engines. The external combustion engine also combines Some of the characteristics of steam engines and internal combustion engines are that the combustion of alcohol is used as the indirect power of the steam cycle, but its capabilities are always somewhat different from those of internal combustion engines. Its uses are also limited to a few high-end vehicles and some urban defense equipment that require quick response and some On the gear drive of the differential engine.”
Seeing Zhang Tie asking about the Sun family's situation in a friendly manner, the other family members looked at Sun Qiming with envy. They didn't know what Master Zhulong liked about the Sun family. After the others introduced themselves, it was fine that Master Zhulong had heard about it. Okay, why did this Sun family member suddenly become interested after introducing himself to Zhulong Zhenren
Seriously speaking, although the Sun family is a little famous in the field of machine manufacturing, it is really no better than others. If the Sun family can make it, they can also make it. Why doesn't Master Zhulong ask me? Could it be because Sun Qiming was the last to speak and paid attention by the way? If he had known this, he would have waited until the end on purpose.
But at this time, people from the other four families could only sit on the sidelines and listen, and they had to concentrate. Apart from sighing inwardly at the Sun family's good fortune, they did not dare to show even a hint of dissatisfaction.
As a master craftsman who hides his identity, Zhang Tie can be said to be a figure who stands at the pinnacle of steam power in this era. As long as a master craftsman is given time, a master craftsman can even create a steam civilization on his own. What Sun Qiming said How could Zhang Tie not know this? Not only did he know it, but he also understood it more deeply than Sun Qiming. Zhang Tie asked him, not really expecting to get any answers from him. It was just an excuse to see if Junior Sister Lu's man was reliable and could bear the heavy responsibility he had entrusted to the Sun family.
"Haha, I mean, if the internal combustion engine can be driven, what kind of internal combustion engine do you think should be developed first?"
Hearing this question, Sun Qiming said without thinking, "This is the holy war, and the survival of the human race is in danger. If there are such sharp weapons, of course we should give priority to the development of weapons that can be used to increase the strength of the human army to defeat the demons and protect us. Comrade, protect my territory!"
"Hahahaha..." Zhang Tie laughed boldly. Sun Qiming seemed to be a gentle and modest gentleman, but he also had a passionate and passionate side. This person's temper matched the gentle and restrained temperament of Junior Sister Lu, which was quite good. No wonder the two Individuals can become husband and wife, "What you said is exactly what I like. How about you come over and take a look at this thing?"
Zhang Tie moved his hand, and a roll of drawings appeared in his hand.
For people like Zhulong Zhenren, it is not unusual at all to have space equipment, but they just saw something appear in Zhang Tie's hand out of thin air. Two of the people sitting here probably have never had the opportunity to see someone in Zhang Tie's hand. The space equipment was used in front of him, so he seemed a little shocked, but because of this, he was even more in awe of Zhang Tie.
Under the envious gazes of the four people next to him, Sun Qiming stood up, came to Zhang Tie with some restraint, and took the roll of drawings from Zhang Tie's hand with both hands.
As soon as the drawing was received in his hand, with its familiar feel and heavy weight, Sun Qiming knew that it was a very formal and professional mechanical design drawing. The texture, drawing method, and regulations of the mechanical design drawing had strict requirements. It is not something that ordinary people can draw casually on paper. Those novels that just draw a design on paper are absolutely bullshit.
"There is a table there. You can spread out the drawings on the table and take a look!" Zhang Tie pointed to a long square table in the flower hall, and then looked at the other four who pretended to be calm, but their eyes were already wandering. People who came to the drawing said, "You don't have to sit down anymore, come and take a look together!"
Hearing Zhang Tie's words, the four people were flattered and stood up from the chairs on which they were sitting on their buttocks. Together with Sun Qiming, they spread out the drawings on the table and looked at them carefully.
It was indeed a mechanical design drawing, not a sketch, but a complete drawing that even included various parameters and materials.
When they first saw the picture, several people immediately recognized that it was a design drawing of an internal combustion engine, an 8-cylinder internal combustion engine design drawing.
The 8 cylinders and the reciprocating piston and crank connecting rod mechanism on the design drawing can be easily recognized by a knowledgeable person at a glance. This is a design drawing of an internal combustion engine. If you are familiar with internal combustion engine design, you can also see it at a glance. The exhaust gas boosting device in the picture.
But that is not an ordinary internal combustion engine design drawing, because the internal combustion engine on that design drawing is very different from the internal combustion engine in everyone's impression. It can be said to be unprecedented.
Looking at the design drawing, Sun Qiming's expression was strange at first, then surprised, and finally became extremely solemn.
The biggest difference from ordinary internal combustion engines is that the 8 cylinders in this design seem to be more than just cylinders, but more like the combustion chamber of a boiler, because the outer layers of the 8 cylinders are hollow and filled with injection molding. Filled with water, to a certain extent, the cylinder itself, which drives the reciprocating piston to move, becomes the combustion chamber of an external combustion engine. When burning, it will automatically heat the water layer on the outer wall of the cylinder just like a boiler. , generate steam energy.
Sun Qiming's fingers slowly slid over the drawings, his eyes focused. When his fingers slid over the drawings, he was already slowly imagining the operating conditions of the engine in his mind. Suddenly, Sun Qiming was shocked. , and I suddenly grasped the essence of this engine design...
"Don't you understand yet?" At some point, when the five people were standing at the table looking at the design drawings, Zhang Tie had already come to several people. As soon as Zhang Tie opened his mouth, those who were carefully pondering the drawings Several people were startled, and each one quickly bowed and pushed away from the table.
"I'm so stupid, I haven't fully understood the design idea of this engine yet!" One person said with some embarrassment.
"This engine looks like an internal combustion engine, but it also looks a bit like an external combustion engine, so..." One person said hesitantly.
"Such a design has never been seen before the Cataclysm, nor has it been seen since the Cataclysm..."
Zhang Tie smiled, raised his hand, and everyone quickly shut up. Then Zhang Tie pointed directly at the picture and started swiping it, "This machine is indeed unprecedented. It is a brand-new design. The core of its design is It embodies the most essential part of the internal combustion engine before the Cataclysm and the core concept of steam power developed after the Catastrophe. Of course you have never seen it. You can say it is an eight-cylinder internal combustion engine, or you can say it is an eight-cylinder internal combustion engine. An external combustion engine with a combustion chamber, I gave it a name myself..." Having said this, Zhang Tie paused slightly and seemed to think over it in his mind, "I call it a dual-drive full-thermal ultra-efficient power system. It's simple. To put it bluntly, it’s called a dual-drive engine…”
