Chapter 191 Single-cylinder alcohol engine
The Royal Institute is located next to Xuanwu Lake. As the highest-level research institute in the Ming Dynasty, it is now a large courtyard.
The reason why the Royal Institute was built so large was purely to facilitate Wang Cheng'en to guide various projects. Except for the princess' similar differences in some aspects, everyone else was far behind. Therefore, many technical problems, as long as Wang Cheng'en saw, can usually be used in place, so Wang Cheng'en's technical resources must be fully utilized. The best solution is to concentrate the research projects in one location. Every minute and every second of Wang Cheng'en's, at least it cannot be wasted on the road. Later generations always say that a certain person "pays" a lot of money in one minute, and Wang Cheng'en's time is calculated based on how many millions per minute.
In order to efficiently utilize the human resources of the institute, some new factories have also moved nearby. If a certain project is successful, it will be transferred to Fang Yizhi, the Ministry of Industry. Whether to start production and how to produce it is the matter led by Fang Yizhi. Of course, the relevant personnel of the institute will follow up the whole process.
In addition, the Military Engineering Academy has also moved together and has set out a trend of "combining industry, academia and research".
There is a sentry in front of the Royal Institute. Such an important place involves many secrets and top scientific and technological talents in the Ming Dynasty. Of course, it is necessary to do a good job in security.
Chongzhen came to the second institute of research. The second institute of research was the Institute of power. The reason why the Institute of power was not ranked first was because one was the Institute of Weapons Research, and as for the third, it was the Institute of Materials Research.
The main building of the Second Institute is a three-story brick-concrete building. The alcohol engine laboratory is located in the room at the end of the third floor. It was originally a small warehouse, but because the alcohol engine was not originally in the Second Institute's plan, this room was temporarily used.
This room is just about forty or fifty square meters. After entering the room, I saw a wooden engine model on one side. This is a single-cylinder engine model. You can see the section of the cylinder. There is a piston installed in the section of the cylinder, which is obvious at a glance. On the other side, there is a cast iron lump, as well as a crankshaft connecting rod, chain, pipe container, etc. Obviously, this is the alcohol engine model.
When Chongzhen saw the wooden engine model, he fell in love with it. This model is really exquisite. In addition to the cylinder being cut open, the valves and other things are cut open. The crankshaft connecting rod is very exquisite. The entire model, except for the sprocket and chain being iron, is all made of wood, including various cams. Well, it is great! So he praised:
"Who designed this wooden model and who made it?"
Wang Chengen pointed to two of the three people who had just bowed to Chongzhen and said:
"The design was designed by Huang Yibo, and the wood model was written by Wang Dahua. Of course, if it were not for this Lord Zhu Shugui, there would be no such thing. It was Lord Zhu who insisted on building this alcohol engine and spending money and efforts, which would lead to today's results."
When Chongzhen saw that Huang Yibo was the youngest, in his early twenties, Zhu Shugui was about thirty years old, and Wang Dahua was probably over forty years old. Only these three people could achieve the results today?
Thinking of this, Chongzhen immediately asked:
"Huang Yibo, come and tell me about the process of making this engine. I want to listen."
When Huang Yibo saw the emperor coming in person, he was indescribable nervousness. His palms were sweating and his face was swollen and red. He stuttered:
"Qi Biao - - Qi Biao - - Wei Miao - - No - - There is nothing to say, or - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Chongzhen thought to himself that this child was a little nervous. It seemed that the child had a good skill in language expression, and his organizational ability might not be even more so, which was why he failed repeatedly in past projects. From this point of view, Zhu Shugui should not underestimate the ability of project organization. We should see how good Zhu Shugui is.
Wang Chengen knew that Huang Yibo's verbal expression skills were very poor, so he nodded and said:
"Mr. Zhu participated in the whole process and played a great role in organization and coordination, and it is not impossible for him to say. What does the emperor think?"
"All right!"
Zhu Shugui was a little flattered, but he was born in a royal family and had seen all kinds of scenes. In addition, he was eloquent, so he naturally had to work hard to show his strength in front of the emperor, so he began to introduce:
"Your Majesty, Weichen knew nothing about this engine at the beginning. Brother Huang took Weichen to see the steam engine and then drew the drawings. While the Huang brothers were drawing, Dahua brothers made various wooden devices according to the drawings. The crankshaft connecting rod Dahua brothers have done a lot, and it is not difficult. The cylinders are different from the steam engine cylinders, but the truth is the same. Dahua has made a wooden model of the steam engine, and the model of this engine is naturally very neat."
Speaking of this, Zhu Shugui pointed to the camshaft on the model and said:
"After making a rough model, it simulates the engine action bit by bit. For example, the first stroke is the intake stroke, and the intake valve must be opened. At this time, the cam on the camshaft must control the intake valve to open, and then the compression stroke. Both the intake valve and the exhaust valve must be closed. The cam on the camshaft must control the intake valve to close, and then after compressing to half the distance, the first injection of alcohol is injected, and when it is almost at the top dead center, the second injection of alcohol is injected. Similarly, the cam must drive a single plunger pump to complete the injection action respectively---------"
Zhu Shugui said while slowly turning the crankshaft, then the piston was up and down, and the valve was opened and closed. At the same time, the plunger camera in the section of the single plunger pump was moving forward and backward. While turning the crankshaft, Zhu Shugui explained the various sequences of intake, liquid spray, pressure ignition, and exhaust in the four strokes of "intake, compression, combustion, and exhaust". After he said this, it was easy to understand. Chongzhen nodded frequently. It seems that the people from the Zhu family are really smart!
According to Zhu Shugui, the most difficult thing is the design calculation of the cam. Later, I simply tried it while calculating, and slowly turned it on the model bit by bit to simulate four strokes. This made the cam design almost the same.
After the model simulation is almost done, the physical engine is designed. Of course, with Wang Cheng'en's guidance, the design is much faster. Given the doubts about sealing, the cylinder was simply designed into a whole. The cylinder hole was drilled out on the cast iron billet, and the valve holes, liquid spray holes, etc. Then, various parts, pipes, etc., and of course, it also includes single plunger pumps, liquid suction check valves, pressure-liquid check valves, and relief valves. These involve liquid seals, and the alcohol viscosity is not sticky enough and it is easy to leak. Wang Cheng'en can only let them think of various solutions, such as homemade flat linoleum and special-shaped linoleum. The penetration problem has not been completely solved so far, but at least it can be used.
When Chongzhen heard this, according to Zhu Shugui's words, it seemed that the engine was just that, basically no difference from a more complicated toy.
Zhu Shugui talked about the process of trying the engine, but he could only tell a long story short. After all, the emperor was not here to listen to the complaints. Although Zhu Shugui has accompanied Huang Yibo and Wang Dahua to make, test and debug it day and night, and I don’t know how many difficulties he has experienced! Needless to say, he has to find someone to work together. All such work is basically Zhu Shugui, who is a child of the royal family, is polite and gives a lot of money.
Of course, the gear factory that Zhu Shugui later built did a lot of work and effort. Anyway, there was no less money or sweat on the engine. Once, there was an accident. The burning alcohol was sprayed through the nozzle, scalding Huang Yibo's hand and raising it for ten days. In short, it was simple to say, but it was very difficult to do. In fact, some aspects can only be considered as just a matter of use. According to Director Wang, it is enough to make a model first and turn it around, and it is not too late to slowly improve the others.
Chongzhen listened to Zhu Shugui's introduction with great interest and asked questions from time to time. Zhu Shugui basically answered questions, which made Chongzhen's impression of this clan's family better.
Then came the engine test run. Chongzhen saw that the closed steel barrel containing alcohol was placed on a wooden table above the engine, and the water barrel used for cooling was also above the engine. This should be to facilitate the pump to inhale liquid.
After checking that everything was fine, Wang Dahua began to shake his hand, and then the crankshaft began to rotate. After shaking it several times, the final explosion sound came, and the engine finally started. After the engine started, Wang Dahua shook the hand-crank water pump to circulate the circulating water, which was used to cool the cylinder.
Chongzhen looked at this simple single-cylinder alcohol engine. The crankshaft rotated rapidly under the driving force of the connecting rod, and the simple chimney emitted white smoke. Recalling the hand-held tractors in later generations, the single-cylinder diesel engine on it was also hand-cranked. Haha, it was a miracle that it was able to run the engine in the 17th century!
-------
After observing the engine test drive, Chongzhen encouraged the three of them and made a promise of a heavy reward. Then he left the engine laboratory and followed Wang Chengen's guidance and entered Wang Chengen's office.
Wang Chengen's office is 60 or 70 square meters, which is much more awesome than the general manager, president, and director of later generations. However, his office is like an exhibition hall, full of various things, some are devices and some are models.
On a row of low wall cabinets, there was a model. Wang Chengen said that it was a model of the Sterling engine. After ignition, it turned out to be turned around. This Sterling engine has never had any practical value. As a thermodynamic teaching model, Wang Chengen thought so. Chongzhen was not interested in such a thing that had no practical value.
However, after Chongzhen saw the engine model created by Huang Yibo, he became interested in the engine. Chongzhen smiled and said to Wang Chengen:
"Huang Yibo is still talented, but he needs someone like Zhu Shugui to help him organize and coordinate, and even help him make a decision when Huang Yibo is hesitant. Regarding this, Zhu Shugui can do it, and I can do it too. So, I plan to find a place in the palace and build an engine research institute to let Huang Yibo go to me. Of course, Zhu Shugui can also go there, and Wang Dahua also wants to go there, and find a few more students. My idea is not to wait for the scale of mining crude oil, and make a diesel engine and gasoline engine first, so that it is good to have some technical reserves, right? You see, after traveling through time, I have not developed a hobby worth boasting so far. Football and Go are just having fun. I found that the engine really gave me a thrilling motivation, which made me feel the urge to be a super enthusiast. How about it? After I invest in the research there, I can share some technically a little bit!"
Wang Chengen laughed, the emperor is really impulsive in doing things, who knows how long he can last! However, with the emperor's attention, the development of the engine will be much faster. He said now:
"If the emperor is interested, that is of course a good thing. The question is, where is the oil coming from now? Sichuan seems to have a little bit. The emperor will never let me drill in Jianghan Oilfield now. I dare say that drilling will take at least two years later. In my opinion, diesel engines and gasoline engines can be tested, and I can also help you solve the problem of electric ignition. The diesel gasoline used for the test drive can also be distilled out a little. But the most guaranteed one is alcohol, that is, ethanol."
Chongzhen said:
"The alcohol engine is also good, so let's get a four-cylinder alcohol engine first."
Then Chongzhen changed his mind and said:
"The alcohol engine actually reminds us that we should not be afraid of spending money in technology. If we spend money on a hundred projects, we will always succeed. Therefore, the next step is to mobilize the people to spend money. You, Director Wang, cannot conquer the world. There must be a better model."
Of course, Wang Chengen knew that over time, the official research institutes will gradually be eaten by borers like many state-owned enterprises in later generations.
Chapter completed!
