The wisdom of ancient people is no worse than that of modern people, it's just that the environment they live in is different.

In the same era, who is smarter than whom may be a pseudo-scientific proposition.

And just when Wang Buxu was about to decide to slow down the research progress on vehicles, he received a piece of news that made the entire Han Dynasty breathe a sigh of relief.

A breakthrough has been made regarding the problem of excessive friction between the cylinder and the piston.

After hearing the news, Wang Buxu immediately put down everything he was doing and hurried to the steam engine workshop.

However, the steam engine workshop at this time was already overcrowded.

Everyone wants to see if this problem has been solved?

From the initial expectation to the later helplessness, this problem has troubled them for too long.

Seeing the emperor coming, everyone subconsciously moved out of the way.

Cheng Juzheng stood there with a smile on his face, looking at the running steam engine in front of him.

For him, he could finally breathe a sigh of relief.

I can finally let go of the big mountain that is weighing me down and relax for a while.

He also changed careers halfway, and was dragged along by the emperor, and he was fooled and encouraged, so he went forward so recklessly.

The more I know, the more scared I feel.

Fortunately, it lived up to expectations. When the huge pressure was about to crush him, Cheng Ju succeeded.

Even Cheng Ju himself couldn't imagine whether he could persist if another month passed.

Every day now is a huge torment for him.

The last time Wang Buxu saw Cheng Ju was not long ago.

But when they met again this time, Wang Buxian's first feeling was that Cheng Ju was in a lot of embarrassment again.

The whole person has also aged a bit. If you can clearly recall the scene when the two met two years ago, you will find that Cheng Ju seems to have aged ten years in just two years.

Although it is tear-jerking.

But the development of a nation always requires someone to shoulder the burden and move forward.

Although Wang Buxian does not need to be responsible for the actual operations, as the helmsman, he is also under a lot of pressure.

"What's going on now?" Wang Buxu asked directly about business before he had time to greet him.

"Your Majesty, this steam engine has been running stably for three days, and it only stopped for two hours every night. We disassembled and compared it this morning and found that the wear of the cylinder is almost negligible. Judging from the current situation

If so, how long this steam engine can be used requires further testing, but it should be guaranteed that there will be no problems within half a month." Cheng Ju said truthfully.

The test only lasted three days, and he only made assumptions based on the known wear and tear.

How long can it be used, and what will happen at a certain stage?

These were things he couldn't predict.

There are no shortcuts to scientific research.

If you want to know the result, you have to let him continue.

It's not like I calculate the wear ratio and then list a numerical value, and finally know its lifespan.

Scientific research is not that simple, and now it is just an experimental environment, and the actual use environment will be worse than the experimental environment.

This is also the reason why many car owners can never beat the Ministry of Industry and Information Technology's fuel consumption, and the power of all mobile phones can never reach the manufacturer's value.

Another point is that the wear and tear mentioned by Cheng Ju can be ignored.

This is not the most accurate statement, but based on the current technology, it is impossible to judge how much wear was caused by this test.

It can only be said that with the naked eye, no obvious wear and tear can be seen.

"What processes have you improved?" Wang Buxian thought for a while and asked.

Although I am not an expert, I still know some basic principles.

The only way to reduce wear is to keep it as flat as possible so that the two parts can be perfectly connected together.

"Your Majesty, this is an idea discovered by one of my students accidentally. All the secrets are in the room!" Cheng Ju did not take the credit.

Although this thing was indeed made by masters like them.

But we absolutely cannot deny the credit of the students. This is also the best thing about the Academy of Sciences now. What is yours is yours and no one can take it away.

The reason why that student did not complete it independently is because his hands-on ability is slightly poorer.

It is impossible for a student who has just graduated to surpass those old masters in terms of practical ability.

This time the two can be said to have formed a perfect complement.

The students expressed their ideas and the master worked on them, and the cooperation was seamless and flawless.

With full of doubts in his heart, Wang Buxuan walked into the room.

However, after entering, everyone was a little confused.

What did I see?

???

lathe???

Wang Buxu blinked his eyes hard and rubbed his eyes subconsciously.

It was finally determined that it was indeed a lathe.

This lathe is very crude. How crude is it?

At first glance, he is just an empty frame.

The facilities provided are also very simple. A small steam engine drives a turntable. There is a hole in the center of the turntable, and the hole is just big enough to put an unprocessed piston in.

Then the steam engine operates and drives the turntable, which in turn drives the piston fixed on it.

On the other side is a fixed milling cutter, which is controlled manually.

This is purely manual and is more difficult to operate than later generations.

During the entire operation, the entire person's mind must be extremely concentrated, and the hand strength must be sufficiently even.

Because there is no protective device, you have to breathe gently at this time, otherwise if your hand shakes, the entire material will be ruined.

Just by looking at this thing, Wang Buxin could guess how difficult it is to use.

The first thing that cannot make any mistakes is the people.

Secondly, the steam engine must be stable enough and the power provided must be strictly controlled.

Otherwise, the speed may be fast and slow, which may affect the quality.

Of course, after seeing this simple lathe, Wang Buxu realized that he had been careless.

It's not that I don't remember it, it's that I really ignored it.

If I had thought of this thing earlier, even if it was just the simplest device, it wouldn't have taken so long.

Of course, let’s put it in another sentence.

When Wang Buxu saw this lathe, he was basically sure that the steam engine outside could run stably for at least two months. If the lubricating oil was strong enough, it might be able to run for four months, or even half a year.

Not allowed.

Compared with the previous two days, this result is now very easy to accept.

Besides, there is still a lot of room for improvement in this broken lathe. After the improvements are completed, some details can be improved.

Similarly, Wang Buxian is also thinking about another problem. If the laboratory data can last for half a year, then in actual applications, although the use environment will be worse, the use time will also be shorter.

In actual practice, it is impossible to only rest for two hours a day. At least for now, you have to stop when it gets dark and can't leave until dawn.

Calculating this way, even if the laboratory data is only half a year, it can be used for between eight months and one year in practice.
