The friction of the steam engine itself is a big problem, and this problem will lead to a series of problems.

In the simplest terms, you take an iron rod and another iron block and conduct a friction test.

Needless to say, within an hour, you can clearly see that a corner of the iron rod will be rubbed off.

There will also be a mark left on the iron block.

But in a steam engine, this is the cause of air leakage.

In addition, the frequency of steam engine movement is much higher than the frequency of human friction, so the wear rate will only be faster.

The current situation is that a new steam locomotive will feel a significant decrease in power after half a day.

This feeling will get worse after one day, and after two days, it will have to be repaired and replaced.

If this was left in later generations and properly overhauled, the engine would even be considered scrapped.

How can a car be used if its engine is scrapped two days after it left the factory?

Does it take longer to repair a car than to drive it?

If a car is built in Luoyang and driven to the Western Regions, how many pistons will need to be replaced?

And there is a more serious problem, because the output of power is steam, and steam is composed of a large amount of water.

Therefore, the use environment is relatively humid.

There would be no problem if it kept working, but how could a steam car keep working?

As long as you leave it for one night, a thin layer of rust will appear. If you leave it for three to five days, the rust will pile up.

Even if lubricating oil is added, it has no effect. It is still due to the sealing reason. After adding lubricating oil, the effect is quite obvious at the time, but the lubricating oil will be pushed out after a while.

Then continue dry grinding.

You can't just add some lubricant after taking a few steps, right?

In this way, a car does not have to pull anything. It only needs to pull water, coal, lubricating oil, pistons and cylinder blocks when going out.

So, this is a matter of materials and design.

Yue Shan was very anxious, but it was useless for him to be anxious about this kind of thing.

The steam engine workshop couldn't solve the problem, so he could only worry about it.

Outsiders only think that life at the Academy of Sciences is very comfortable.

As long as a craftsman enters the Academy of Sciences, he will have an official status, which is really enviable.

They did think so when they first came here, and even the people at the Academy of Sciences themselves thought so.

But now, everyone knows.

Official status is not that easy to get, and the treatment is not that easy to enjoy.

I have endured hundreds of days and nights, but still no progress has been made.

Huge pressure fell directly on them like a huge mountain.

The imperial court invested heavily in steam locomotives, and almost two-thirds of the scientific research funds were used for this purpose.

There are no restrictions on the manpower and materials needed, just as much as you need.

When the intensity of support is not proportional to the rewards, no one will panic at this time.

Steam engine workshop!

If Yue Shan's hair is falling out strand by strand.

So people here are losing their hair in handfuls.

Now the entire project is stuck with them. They thought it was just a small problem, but it turned out that this small problem has troubled them for so long.

The materials were changed countless times, and they used all the materials they could think of, and even tried various combinations.

But the effects are not good. Even if some materials are improved, the improvement effect is not enough for normal use.

If one year is increased to two years, it may still be a huge breakthrough, but if one day is increased to two days, what kind of breakthrough is this?

Simply because this material is more suitable than that one.

Overall, I have tried everything that needs to be tried.

Cast iron, wrought iron, steel, bronze, and even carved from wood and stone.

But it's of no use.

The only thing that performed better was steel.

This is because steel is hard enough and more wear-resistant than iron.

They also tried reducing the size of some pistons to reduce friction.

But in this case, the air leakage will become more serious and the power output will decrease sharply.

According to this design, if you want to drive a vehicle towing a tractor, you will need a larger steam engine.

Therefore, the importance of some theories becomes prominent at this time.

This group of people does not have very profound theoretical abilities, they just have strong practical skills.

Faced with problems that arise, the only way is to solve them through continuous trial and error.

If there is theoretical support, this scope will be effectively narrowed and the probability of success will be increased.

Regarding this issue, Wang Buqi, who knew astronomy and geography, could only scratch his head.

Although I am not an expert on engines.

But at least Wang Buxian knew that there was a sealing ring on the engine piston.

The role of this sealing ring is very important. It can reduce friction problems to a certain extent while ensuring sealing.

Of course, the most important issue is the material.

In other words, it is a processing problem.

What is the current piston?

They are all rough guys and have not been polished seriously at all.

In other words, the polishing technology cannot meet that requirement.

Later generations used materials, coupled with CNC grinding, modified the cylinder to reduce the frictional resistance, and added the assistance of lubricating oil, it took a few combined efforts to solve this problem.

And now?

It is the hard grinding of dry wood and fierce fire.

Maybe one day my face will be bad and it will snap.

The only suggestion Wang Buxu could give them was to work on polishing the cylinder and piston. Otherwise, they could only leave it to fate.

We can’t send people to South America to get the rubber trees back now, right?

And what about lubricants?

Animal and vegetable oils are also often used.

In this era when everything needs to be started from scratch, creating something like this requires the support of the entire industry.

Wang Buxu suddenly discovered a fact that he had taken for granted.

It’s not that the steam engine was developed too early.

But it was a bit reckless to put the steam engine into use so early.

But as a person from later generations, the steam engine has been developed, and the principle is no longer problematic.

Under such circumstances, it was obviously difficult for Wang Buxu to restrain his temper and not put him to use.

No one understands the significance of the emergence of the steam engine better than Wang Buqi.

As long as the current problem is solved, the problem of the internal combustion engine will soon be solved.

The principles of the two are similar, but there are some differences in details.

Regarding the pace of science and technology, Wang Buxian has never given up.

But facing the current reality, Wang Buxian was brought back to reality.

Wang Buxu had to think about a question frequently, that is, should he temporarily suspend the practical use of steam engines?

Should we correspondingly reduce investment in vehicle research and redistribute funds equally to various departments?

Doing this may delay the progress of vehicle research, but no one can say for sure. What if a department solves this problem by mistake?
