Professor Jiang Qing began to order the students to use mechanical products equipped with steam engines and machines equipped with diesel engines respectively.
He took the spare diesel engine to the laboratory and personally demonstrated the diesel engine to Emperor Su He and Prince Su Shu, among other senior officials of the empire.
Professor Jiang Qing knew that the purpose of his public experiment was to obtain more funds.
He knew very well who was in charge of the empire's scientific research funding.
Emperor Su He and Prince Su Shu took time out of their busy schedules to come here. Even though they had seen clearly what he had just done, they still had to sell the future of diesel engines to them face to face.
As long as the current emperor and the future emperor of the empire are optimistic about diesel engines, the internal combustion engine project he founded will definitely usher in great development.
Professor Jiang Qing led some people to the laboratory, and the rest of his students followed the teacher's instructions and continued to demonstrate the power of the diesel engine on the playground.
Among the several mechanical products that the internal combustion engine project team simply modified, the Longchang car is the most contrasting product.
When a steam engine is installed on a car, enough space must be left in front of it to install a small boiler.
For a car equipped with a diesel engine, without the burden of the boiler, there will be a lot of leakage from the car's chassis.
Steam engine cars are similar to previous horse-drawn carriages, and you also need to step on a stool to get on.
As long as the door of a diesel engine car is opened, you can easily enter inside.
The most critical point is the startup time.
While the steam engine car is still igniting and preheating, the diesel engine car has started the diesel engine through the crank handle.
When everyone saw how convenient diesel engine cars were, they started talking about it.
“It only took two or three minutes to get the car moving.
It was winter and my housekeeper got sick and forgot to preheat the car for me in advance. It took at least an hour to preheat the car steam boiler.
I was in a hurry to get to the morning meeting, so I could only ride in my friend's car, and was laughed at for a long time by him writing poems.
After diesel cars are launched, I will definitely get a new car.
This kind of car is so convenient to use, you don’t need to wait long, you can stop and go. "
“Diesel engine cars are very fast, and it looks like they can definitely surpass horse-drawn carriages and steam engine cars.
A fast means of transportation is a must.
Back then, I received a big order via telegraph and had to rush to the train station within half an hour to get on the train heading south to Chongqing.
If you miss this time, you will have to wait until the next day for a train. It will take too long to reverse and cannot meet the schedule.
The car could not start and the carriage was too slow.
I could only ride my domestic horse and rush to the train station at a very fast speed, which made my thighs bleed.
I never want to experience this feeling again. "
The diesel engine car was only demonstrated for a short while, and the rest of the diesel engine products continued to be displayed.
Professor Jiang Qing’s students displayed diesel engine generators respectively.
Its power generation efficiency is much higher than that of today's steam engines.
Before the price of diesel does not rise, it is more suitable for power generation than coal, but it is certainly not comparable to extremely low-cost hydropower.
Diesel engines generate electricity, which only allows onlookers to see the tip of the iceberg of diesel engines.
Professor Jiang Qing’s students, they showed the most interesting point of the diesel engine, that is, compared with the steam engine, what is the power output?
Steam engines can replace water power at no cost. In addition to being easy to use, the most important thing is its powerful output.
This characteristic of formal steam engines completely eliminated hydraulic machinery.
Professor Jiang Qing's students used steam engine cranes and diesel engine cranes to lift the same things.
It proves to the world that the diesel engine is lightweight and easy to use, and the power output of the diesel engine is by no means inferior to that of the steam engine.
The excavator that came out at the end was the most shocking.
The originally very heavy excavator was reduced in size several times after removing the huge boiler.
But the flexibility of diesel engine excavators surpasses that of steam engine excavators.
The excavator's traveling speed and digging speed are much faster than those of steam engine excavators.
Professor Jiang Qing's students mainly displayed these three types of machinery. During the display of these three types of machinery, they also displayed some small diesel engine products, involving many industries.
The guests on the playground saw Professor Jiang Qing's students displaying the diesel engine.
Some people find something unusual.
"Brother Zhang, why do you think the diesel engine only runs for ten minutes at most from startup to operation?
Is this a defect in the diesel engine that prevents it from running for a long time?
Diesel engines have such major flaws that they certainly cannot be promoted.
Although steam engines have various shortcomings, under normal circumstances, the steam engines in my site are shut down for inspection only once a month.
Lao Wang's factory may not be inspected once a year. If the steam engine parts are broken, they will be replaced with new ones. "
Someone looked at the tender-faced student and shouted, "Student boy, is your diesel engine not working?"
Why is it that my time is shorter than that of the old man, and I have no staying power at all.
These useless machines are sent to factories for free. "
When Professor Jiang Qing's students heard this question, they blushed and hesitated to speak.
Professor Jiang Qing was transporting the diesel engine to the laboratory building via the elevator.
He also had some guesses about what might happen on the playground.
After all, the emergence of diesel engines has touched the interests of many people. These people's interests have been harmed. Even if they have not yet reacted, they subconsciously hate diesel engines in their hearts.
But he no longer cares about the performance of these people. No matter what they do, it will not affect the future of diesel engines.
Only the Emperor Su He and the Prince Su Shu in the laboratory building can really have the power to influence the future of diesel engines.
Emperor Su He is ready to leave Huaxia University.
The diesel engine was really running, spitting out billowing black smoke, and he was very happy.
This marked the official start of the Empire's internal combustion engine technology.
He saw that the diesel engine only ran for a few minutes before being hastily stopped.
The diesel engine had some flaws, which he was totally fine with.
Diesel engines have already appeared. As long as investment is increased in the future, this technology will inevitably become more and more mature.
When you invest money in scientific research, you are most afraid of not being able to see future prospects.
Diesel engines can already see the future. Anyone with a good vision will not object to investing money in diesel engine projects.
Principal Xu Qinqing knocked on the door. She was allowed to enter the room. She wanted to open her mouth, but she hesitated.
Emperor Su He saw that she wanted to speak but was very hesitant.
He smiled and said: "Shaoyao, if anything happens, just say it directly.
Seeing the success of this diesel engine project, I agreed to some simple things. "
Xu Qinqing heard Emperor Su He say this and saw the smile on Emperor Su He's face, knowing that Emperor Su He was very happy now.
Then she said her purpose: "Teacher, Professor Jiang Qing wants to show you the diesel engine in person."
As soon as Xu Qinqing opened his mouth, Emperor Su He knew what Professor Jiang Qing was planning?
The tricks these researchers know are very old-fashioned and can be easily seen through.
"I agreed, and I also want to see what a diesel engine looks like.
I looked at the previous information and it is only a matter of time before diesel engines replace steam engines.
It is precisely because of this judgment that I pay attention to the diesel engine project. "
Principal Xu Qinqing received permission from Emperor Su He, and he immediately contacted Qin Shanshui, the commander of the Qilin Guards, on how to visit the diesel engine while ensuring the safety of Emperor Su He.
Qin Shanshui's pressure increased sharply, and he immediately arranged for Qilin Guards to conduct a detailed inspection of Professor Jiang Qing and his party.
They finally determined that Professor Jiang Qing and the diesel engine could be experimented in the laboratory.
But while the machine is running, Emperor Su He and Prince Su Shu will not enter the laboratory.
Qilin Guard has already conducted a detailed inspection of Professor Jiang Qing and his party.
Commander Qin Shanshui knew that Professor Jiang Qing and his party had absolutely no way to bring weapons to the laboratory.
His only concern was the huge diesel engine.
Any accident during the disassembly process may cause serious consequences.
Professor Jiang Qing contacted Qilin Guard, and he quickly agreed to Qilin Guard's arrangement.
His purpose was just to get close to His Majesty the Emperor and let His Majesty the Emperor have an impression of him.
Emperor Su He stood outside the laboratory door. He could see the situation inside the laboratory through the safety glass.
This diesel engine is exactly the same as the one demonstrated on the playground, except that some details can be seen clearly.
The diesel engine had been running for nearly twenty minutes, only to hear a click and suddenly stalled.
When the voice sounded, the guards of the Qilin Guard immediately formed a human wall in front of Emperor Su He and Prince Su Shu.
They entered the laboratory to check and confirmed that it was safe. It was just a false alarm.
Emperor Su He entered the laboratory and saw Professor Jiang Qing leading his students to dismantle the diesel engine.
When they saw the emperor and the prince coming in, they immediately prepared their luggage.
Emperor Su He said in a calm tone: "You are busy with business, don't worry about etiquette."
He stopped Professor Jiang Qing and others from saluting, and asked curiously: "I saw the diesel engine forcibly stopped running quickly on the playground, and I knew that the diesel engine had some defects.
What exactly is the reason for the defect? "
Professor Jiang Qing moved quickly. He took apart the diesel engine casing and saw that the crankshaft and other parts inside were twisted.
“Your Majesty, it’s hard for a clever woman to make a meal without rice.
I never expected that developing an internal combustion engine would be so expensive.
The school has tried its best to support the internal combustion engine project team, but we have also exhausted almost all the funds for the project.
The cause of this problem in diesel engines requires long-term testing to find out, but due to lack of money and other reasons, the progress has been very slow.
Thanks to the breakthrough in Imperial Steel technology and the emergence of electric motor boring machines.
I made the cylinder of the diesel engine without any hindrance.
But it is precisely because the power of the diesel engine is too strong that the crankshaft connecting rod runs at high speed. Even high-strength steel cannot withstand such an environment.
I tried to use water to cool the parts, which was only partially successful, the diesel engine could run normally for a while, but then it also caused the parts to warp abnormally. "
Emperor Su He took over the damaged and deformed parts.
He asked curiously: "I am not very familiar with mechanical processing, but what kind of talent does the empire have?"
Emperor Su He gave Qin Shanshui a few instructions and found top scholars in the mechanical field at the scene.
Guo Zhenshan, a mechanical engineering academician who designs and manufactures railways and trains, was approached.
Guo Zhenshan watched the diesel engine to find new power for the next generation of locomotives.
Today's trains use steam engines, and various indicators have reached the limits of steam engines.
A lot of money has gone into the Empire's train project, but there has been no progress for three years.
When Guo Zhenshan heard the news about diesel engines, he immediately felt that this was a new breakthrough, so he came to visit the diesel engine test.
While he was chatting with his friends, he was called away by the Qilin Guard.
Guo Zhenshan learned about the situation and came to the laboratory with confidence.
Professor Jiang Qing was very excited when he saw Guo Zhenshan.
Guo Zhenshan's famous name is simply like thunder.
Many of the textbooks he uses for teaching were written by Guo Zhenshan himself.
Professor Jiang Qing believes that he has some fantastic ideas, but his level of research in the mechanical field is definitely not as good as Guo Zhenshan’s.
He immediately handed the damaged parts to Guo Zhenshan.
"Academician Guo, it is official that this part is often damaged, which causes the diesel engine to run for a short time.
You have rich experience, please give me an idea. "
Guo Zhenshan took out his magnifying glass and carefully observed the damage to the parts. At the same time, he asked Professor Jiang Qing how the parts were operating in the machine.
After Guo Zhenshan read it, he took out the small hammer in the laboratory and kept tapping on the parts.
He looked serious at first, but soon a smile appeared on his face.
"I know the reason why this part was damaged. The diesel engine piston did work too fast, driving the crankshaft connecting rod to run at high speed.
This damaged crankshaft is mainly caused by high temperature due to wear between parts.
Why don't you use engine oil? This is the simplest solution. This problem should not occur. "
When Professor Jiang Qing heard the solution, he asked in surprise: "What is engine oil? I have never heard of it at all."
Academician Guo Zhenshan slapped his head. This is the biggest problem encountered by the imperial scientific research community now, information is not flowing smoothly.
Some of the results of the Royal Academy of Sciences are something they have taken for granted internally, but the outside world is not aware of them at all.
“To put it simply, engine oil is liquid lubricating oil.
It not only lubricates the machine, but also quickly conducts heat away from the machine. "
When Professor Jiang Qing heard these two functions of engine oil, he was surprised and said: "There is really such a thing as engine oil, and it perfectly solves the problems I encountered.
With oil to lubricate the machine and dissipate heat, I could reinstall the gear set that I had no choice but to remove before and reinstall it on the diesel engine.
In this way, both the transmission function of the diesel engine and the power output of the diesel engine will be more stable. "
Academician Guo Zhenshan nodded and said: "Motor oil is very useful, especially for machines with built-in gears.
In some simple steam engines, except for the mechanical device of connecting rod and crankshaft, all its external gears are placed outside.
Workers can observe the condition of these parts in real time and observe in time if a problem occurs.
Precision steam engines and diesel engines have many gears and other mechanical structures inside, and external lubricating oil has little effect. Soaking these machines in engine oil can solve many problems. "
After Academician Guo Zhenshan asked Emperor Su He for instructions, he sent someone to the Royal Academy of Sciences to get engine oil. At the same time, he taught Professor Jiang Qing how to use engine oil.
Professor Jiang Qing learned quickly. He understood the functions and usage requirements of engine oil.
Make some improvements to the diesel engine so that it can hold oil without spilling it due to bumps.
Professor Jiang Qing hopes that engine oil will be useful so that diesel engines can run for a long time and replace steam engines. (End of chapter)
