"Why is this chimney emitting black smoke? Is the air inlet too small?" Dong Shuheng said loudly again.
"Isn't it because of the diesel?" Bob directly grabbed his hair with his lubricated hands, and the fluffy hair instantly formed a lock.
He always thought that diesel is less volatile than gasoline, so it is naturally more difficult to burn, so there will be black smoke.
Dong Shuheng has seen a real diesel engine. When he was a child, he drove a tractor to plow the fields.
"Bob, I think if the diesel is fully burned, there won't be so much black smoke. You'd better try to expand the air intake."
Dong Shuheng played a very important role in the development and manufacturing process of this diesel engine. Therefore, Bob did not feel that he was an amateur directing an expert.
In fact, it was Dong Shuheng who led Bob into the field of internal combustion engines.
The so-called internal combustion engine is a name that is different from an external combustion engine such as a steam engine.
Liquid fuel is injected into the cylinder and mixed with air for combustion, increasing the air pressure in the cylinder, and then pushing the piston and crankshaft to move. Finally, the chemical energy is converted into kinetic energy.
The principle seems very simple, and many of the mechanical principles used in manufacturing steam locomotives can be used.
The biggest problems lie in the fuel and the materials used to make the internal combustion engine, mainly the materials used to make the pistons.
To ensure the air tightness of the cylinder, the piston and the cylinder must fit together. This requires that the piston cannot be too hard, otherwise it will scratch the cylinder wall.
But it cannot be too soft, otherwise it will not be able to withstand the force of the crankshaft.
Moreover, its melting point cannot be too low, and the temperature in the tank must be ensured so that it does not melt.
Copper alloy is a good choice, and the hardness can be controlled by adjusting the proportion of tin in it.
This method has been known to our ancestors thousands of years ago when they used bronze vessels.
Of course, copper is too expensive, and China is still relatively short of copper.
The southwest region is the region with the richest known copper deposits, but it has been developed for thousands of years, and the mineral deposits have either been exhausted long ago, or they are in places that are difficult to mine.
Dong Shuheng knows that there are many copper mines in the grasslands to the north. But there is no exploration yet.
At present, China still mainly relies on imports of copper. Dong Shuheng mined some copper mines in Southeast Asia. In addition, he also imported a large amount of copper from the British and Spanish.
Now China needs copper to make bullets, cables, and even copper coins.
There are so many places that need copper. There are a lot of copper mines in Peru, and there are also a lot of copper mines in the Philippines, but the mines there are mainly controlled by the Spanish.
After Peru became independent, the British also penetrated there.
Perhaps when Dong Shutong brings the Chinese and the Indian revolution succeeds, Dong Shuheng will be able to go mining there.
"President, I will experiment with the issue you mentioned." Although he did not have a deep understanding of the combustion rate of diesel, Bob still chose to believe Dong Shuheng's words."
"I will improve the air inlet. Maybe the filter element in our air inlet is clogged. In short, I understand what you mean is that this machine does not have enough air entering the cylinder."
"Well, Bob, don't worry, you must know that this is an epoch-making invention, we must slowly explore in experiments, discover problems, and solve problems!" Dong Shuheng comforted Bob.
Dong Shuheng chatted with the three of them for a while before leaving. He was in no rush to take out the internal combustion engine. The longer the current experimental verification phase is, the more mature the internal combustion engine technology will be in the future.
After leaving the "Five" office, Dong Shuheng attended a meeting between teachers and students of the academy and paid attention to everyone's study and life in Xinjing.
Next, he left the academy. Instead of going back to the western suburbs, he went straight to the supply and marketing supermarket outside the front door.
This is the largest supply and marketing supermarket in the entire Xinjing area.
There are also supply and marketing supermarkets in the western suburbs, but the residents there are all Chinese workers.
This kind of place is naturally the best in all aspects. Dong Shuheng believes that there will be no problems there.
Dong Shuheng and Wei Yuxiang walked into the supermarket together, surrounded by some internal security personnel.
Almost no one here knew Dong Shuheng. Seeing his attire, they thought he was a small employee of the Chinese government.
He doesn't look like a high official at his age.
There is a long counter in the supermarket that separates the inside and outside. The products are placed in different areas by category. Each area has a salesperson responsible for sales and explanations.
This supermarket is much more formal than the grocery store-like supply and marketing supermarket in Nancheng.
The salespeople inside were very busy, and there was a long queue in front of almost every counter.
Dong Shuheng originally wanted to go up and inquire about the situation, but after seeing the situation at the scene, he quickly gave up the idea.
He left the supermarket with Wei Yuxiang, then turned around and walked towards the original Shuntian Mansion.
He was going to go to the Xinjing government to sit down.
Arriving at the Xinjing Municipal Government, Wei Yuxiang went to report. After a while, Dai Yuanhuai came out to greet him.
"President, why are you here?" Dai Yuanhuai quickly invited Dong Shuheng inside.
"Hey, why do you have so many messy things in your yard?" As soon as Dong Shuheng entered the municipal government compound, he saw that it was filled with all kinds of tools and vehicles. It was like a product exhibition center.
"Hey, President, this is all caused by Song Qing. Our city government is now going to turn into an employment agency."
"The economy inside and outside the capital's walls used to depend on the princes and nobles and various government offices." Now we have come in, but the princes and nobles are gone, and many people in the industry have lost their livelihood."
"So I told Song Qing to take care of this matter. He has many ideas, which really helped him develop a lot of businesses."
When Dong Shuheng asked about this, Dai Yuanhuai started to complain and boast.
"Old Dai, you have done a good job. This is to do practical things for the people. By the way, I just went to the supply and marketing supermarket. Why are there so many people queuing there?" Dong Shuheng asked as he walked.
"This... President, I have also gone to see him. Under normal circumstances, he would line up every day."
"I checked and there are several reasons: First, didn't we release a lot of military stamps? Everyone probably has some distrust of military stamps, so they quickly spent them after getting the military stamps."
"Second, after our new government was established, many small traders did not dare to come out. In the past, each small market in the capital had a system, but now the old system has been broken and a new system has not yet been established. Small markets
Order has not yet been restored."
"Third, the previous wars have indeed affected the lives of many people. Everyone's homes are short of supplies and need to be replenished urgently."
"President, I think this is temporary, and it will return to normal after a while."
Dai Yuanhuai's analysis was very reasonable. Dong Shuheng nodded: "Old Dai, what you said makes sense, but our government still needs to be more proactive."
"I think we can also open those small markets. There is no need to let the people do it spontaneously like before. Then a bunch of ruffians will appear to occupy the territory. It is better for us to standardize them from the beginning."
"This can give some small traders a way to survive, and those people who have lost their livelihood can also set up stalls to maintain their lives."
Dong Shuheng still remembers that there were some small convenience markets in night markets in later generations. Residents in the city could live conveniently and small traders could make money.
The government only needs to provide some managers. Managers can also be hired from the public, which can solve part of the employment problem.
Dai Yuanhuai thought for a while and said: "I think this is okay. It turns out that many markets have spontaneously formed in this old city. We can plan out the open space in front of some shops and rent them to people at low prices to set up stalls. Then send out
Market administrator partition management.”
“President, all the famous markets in this old city are listed in their place names, such as Flower Market Street, Luoma Market, Gangwa City, Coal Market Street, Mishi Street, Jewelry Market Street, Caishikou, Dengshikou, Yangshikou,
Dongxiao City, Xiaoshikou, etc." Dai Yuanhuai is quite familiar with the old city.
"Lao Dai, don't you think these markets are also part of the capital's culture?"
"I think you can make plans based on this to not only make these markets convenient for people's lives. In the future, anyone who comes from other places and comes to the capital will want to visit these places. They may be the label of the old city of Xinjing in the future.
"Dong Shuheng remembered that people in later generations often said that cultural inheritance is also a kind of resource.
Dong Shuheng initially placed the administrative center in the western suburbs but not in the inner city. Part of the reason was that he wanted to preserve the old city and pass it on as a cultural heritage.
This place has been the capital of China for five to six hundred years. It has too many historical memories that are worth cherishing by all Chinese people.
Not only the capital city, but also ancient capitals such as Jiangning, Xi'an and Luoyang will be preserved.
"President, you are still thinking in the long term. There are fewer people in the old city now, and it seems a bit depressed. But if we develop well, we will definitely attract more people." Dai Yuanhuai felt as if he
Zi was awakened by Dong Shuhengdian.
My own ideas for governing the city are still too narrow.
"Let's reopen the small market first. Our supply and marketing supermarket alone cannot meet the needs of the people. When the academy enrolls students in September, there will be tens of thousands of students in this old city alone, and it will be bustling by then.
.”
"Furthermore, the government official recruitment examination in August will also be held in Xinjing. There will definitely be many people coming to take the exam, which will also increase the popularity of Xinjing. There will be a ceremony in November and a national conference at the end of the year."
"As a capital city, there will be many opportunities to show its face here in the future. We cannot let people say that our Renaissance Army cannot manage the city. Once the capital is in our hands, it must become more prosperous, more beautiful, clean and tidy." Dong Shuheng said.
"Well, President, I understand. We have started to control several ditches. Next, we will promote the use of briquettes throughout the city, cement the streets, dig sewers, and build public toilets. We promise to use these briquettes throughout the city.
The city becomes better based on its original foundation.”
Dong Shuheng nodded. He was not afraid that local officials would make mistakes, but that local officials would do nothing because they were afraid of making mistakes.
In terms of urban construction, the Chinese government also had a precedent of success. The construction of Gaoyou and Yangzhou was successful.
Gaoyou quickly developed into a light industrial city, while Yangzhou became a distribution center for inland commodity trade.
After leaving the Xinjing Municipal Government, Dong Shuheng returned to the Summer Palace.
Today two younger sisters came over from the south. They want to invest in a leather bag factory here in Xinjing.
According to Dong Shuheng, since Yunmei wants to become an international luxury brand, how can it not make bags.
In later generations, "cure for all diseases" has been talked about by countless women. How many women would rather not eat well than buy a famous brand bag.
The north is the origin of fur goods, and skilled fur goods merchants can be recruited here, so it is best to set up a factory in the north.
Back at the summer palace, Dong Shuheng saw his two sisters visiting the garden, led by Feiyan and Duji.
Seeing Dong Shuheng coming over, Shuyun nodded and said hello in the same ladylike manner as before.
However, what makes Dong Shuheng strange is that his sister Shumei does not rush to his side like before.
It seems that my sister has really grown up and matured.
Dong Shuheng walked up to a few people and subconsciously wanted to touch Shumei's head, but stopped as soon as he raised his hand in the air.
"How's it going? Have you two settled your affairs?" Dong Shuheng asked with a smile.
Knowing that the two were going to Xinjing to set up a factory, Dong Shuheng informed Liu Wenjin one step ahead and asked Liu Wenjin to make arrangements for him.
Liu Wenjin is a person who knows how to solve problems. Looking at the expressions of the two sisters, it is obvious that the matter has been perfectly resolved.
"Well, it's all done. It didn't take any effort. It was all arranged by Mr. Liu. Brother, you must have arranged it in advance." Shuyun said.
"In fact, I don't need to arrange this matter. Liu Wenjin is currently attracting investment. He is eager for you to invest in it!"
Dong Shuheng knew that his sister did not want to live under his wings all the time. The two of them hoped to be recognized by others with their actual actions.
Of course, it may be more about getting Dong Shuheng’s approval.
"How about it? Sister, are you interested in investing in a ranch, raising your own cattle, and raising cattle with better leather? In fact, good cowhide is best without scars, and herdsmen don't understand this. They don't want to beat cattle and sheep.
You will be soft-handed. So you'd better hire herdsmen to raise cattle yourself. You need to repel mosquitoes for these cattle, reduce mosquito bites, and prevent them from fighting with each other..." Dong Shuheng captured a leather merchant in his previous life and knows some of the secrets of the leather industry.
.
"Well, I didn't expect it at first, but after hearing what you said, I really had such a plan." Shuyun said with a rare smile.
"Let's go and eat first. Let's chat at the dinner table." Dong Shuheng greeted.
Everyone stepped forward, but Shumei sneaked behind and pulled Dong Shuheng's sleeve.
Dong Shuheng knew what his little sister was going to whisper to him, but he was afraid that his sister would hear it.
"Tell me, what's the matter?" Dong Shuheng asked in a low voice.
"Brother, I want to go to Europe. Our company is planning to hold an exhibition there." We had contacted Minister Wang before, and he expressed support for this. He said that there is a Chinese style in Europe now, and it is to promote us.
Great time for the product.
"Is it because your mother and sister won't let you go?"
The little girl nodded aggrievedly, as if to say: "They all bully me, my brother will help me make the decision!"
"This matter is indeed difficult to handle. I can't help you sneak out, otherwise your mother will have to fight against me. Give me a few days and I will think of a solution."
"Brother, you must have a way. You are the leader of a country and you have a golden tongue. Who dares not to listen to what you say?"
"Hey, you can't talk nonsense outside. Your brother and I are not the emperor, and you are not a princess. You have to be polite and keep a low profile in front of outsiders, you know?" Dong Shuheng interrupted quickly, and this girl said
Where should I follow?
"Yeah, I got it, brother." Seeing her brother coming to teach her a lesson, the little girl was completely unhappy, but now that she was asking for help from her brother, she didn't dare to show her dissatisfaction.
"Actually, it would be good to go abroad for a visit. I will find a solution for your matter, don't worry." Seeing that his sister was a little unhappy, Dong Shuheng quickly comforted her.
After Shumei heard this, she immediately burst into laughter and hugged Dong Shuheng's arm and shook her: "Thank you, brother, I know that brother is the best."
I originally thought that this girl had grown up and matured, but I didn't expect that she was just pretending. Dong Shuheng sighed deeply in his heart.
