Liu Ponu wanted to prove himself right to the world with real objects, but he obviously overestimated his rookie-like scientific research ability, and also underestimated the difficulty of steam engine research.

Two months passed in the blink of an eye, and under Liu Che's special care, no one came to disturb him in the past two months.

A lot of problems have been solved, but it obviously feels like it's almost there, but in the actual experiment, it is full of problems.

Originally, Liu Ponu thought that it didn't matter if the problem of air leakage could not be solved for the time being, as long as he could provide the power to drive the new plow, he could accept the reality of air leakage.

But the result quickly slapped him in the face, and now it is no longer simply a matter of air leakage or not air leakage.

If the problem of air leakage is acceptable, then the problem of wear and tear is not acceptable.

It was just an experiment, Liu Ponu didn't know how many times he had tried it, and the self-made piston had already been worn out by a small circle, the air leakage was getting more and more serious, and the power was plummeting.

It's like this when it's tested, and when it comes to the application, no one can afford it, this thing is used for work, who wants to change the piston after a few days?

The real lubricating oil problem could not be solved for a while, and Liu Ponu used tung oil instead.

The problem of severe wear and tear has been greatly alleviated, but new problems have arisen.

Because the sealing is not good, with the continuous repetition of the piston movement, the oil leakage is getting more and more serious, no matter what kind of fairy idea Liu Ponu adopts to solve this problem, there is no way to ensure that the last step can seal the tung oil without loss.

And looking at the steam engine that is getting bigger and bigger, Liu Ponu can't help but make a difficulty.

"I really want to build a gadget the size of a walk-behind tractor, and if I continue to do this, I'm afraid I'll have to make it the size ......of a locomotive," Liu Ponu looked frustrated.

Liu Ponu knew where the problem was and how to solve it, but he couldn't find the materials to solve the problem, so at this point, the steam engine couldn't go on.

In order to solve the problem that the water inside the boiler continues to shake with the harsh use environment and causes it to enter the cylinder, Liu Ponu even solved the problem of adding a screw device in the ventilation pipe to prevent the water from flowing out, but now he can't solve the problem caused by a sealing gasket.

If Liu Ponu has a powerful plug-in that can allow him to cross once, he will definitely go to the UK and ask Watt, how did you solve this problem?

"Your Majesty, do you think we will take a detour? Why don't you take a break and let them study it slowly? Liu Qu, who had been following Liu Ponu's side, couldn't help but persuade.

followed Liu Ponu for a few months, and he did more than Liu Ponu.

Although Liu Ponu often gets started to do it, how dare Liu Qu stand next to him and stare at Liu Ponu with such big eyes?

So most of the time, Liu Ponu commanded, Liu Qu took people to do it, Liu Ponu really couldn't watch it, so he would fiddle with it himself, although the level was not as good as Liu Qu and them.

But after a few months of training, Liu Qu almost became an expert in the study of steam engines.

At least in this era, these people in this courtyard are experts in steam engines, and each of them has also put forward a lot of useful opinions in practice, although more of them are nonsense.

Seeing that Liu Ponu still had some thoughts about drilling the horns, Liu Qu couldn't help but speak again: "The prime minister is over, the whole family is just a matter of time, although the father and son of the servant are more excessive, but the wife of the servant is the queen's sister after all, and His Majesty doesn't want to do things too much, the old slave heard that His Majesty intends to let the servant go home to support the elderly, and the imperial historian Ni Kuan hopes to return to his hometown on the grounds of old age and lack of energy, and now the atmosphere in the court is a little tense, and the king should first stand up to stabilize the court situation, and then study the steam engine." ”

"Besides, don't you often say that you can't always do things behind closed doors, and when you don't have ideas, you go outside for a spin, maybe inspiration suddenly comes?"

Listening to Liu Qu's advice, Liu Ponu was stunned for a moment.

For more than two months, he had not heard anything outside the window, and his heart was full of pounces on the steam engine.

Liu Che knew what he was doing, but those ministers didn't know.

Looking at the disappeared and traceless Liu Ponu, the thoughts in everyone's hearts suddenly rose again, and someone heard that Liu Ponu was in the courtyard of the palace, and he had never left half a step for several months, and the emperor had not stepped into it after going once.

When asked about the people around the emperor, everyone kept silent.

This abnormal reaction made people grasp a trace of unusual aura, it seems that Liu Ponu has fallen out of favor?

Although there are still people in and out of the courtyard, a large number of raw materials are transported in, and even the black smoke of the iron-making furnace can be seen working every day, but Liu Ponu himself is never seen, and then thinking of the attitude of the emperor and the people around him, everyone can't help but suddenly realize, isn't this grounded?

So, someone started to get active.

Seeing that the prime minister was going to be unlucky, the rest of the princelings began to sit still, and if they didn't fight back with such a good opportunity, what were they waiting for?

Sun He, the servant who was shot in the same batch as Prime Minister Shi Qing, took on the task of counterattacking the protagonist, this time he didn't want to and couldn't, who made his son's problem more serious?

But what everyone didn't expect was that in the face of the counterattack of Gongsun He and others, the emperor did not choose to compromise, but reprimanded Gongsun He fiercely, and immediately ordered Gongsun Jingsheng to be strictly investigated.

Violent Shengzhi already had a large amount of evidence of Gongsun Jingsheng's crimes, and after receiving the emperor's instructions, he immediately conducted a more in-depth investigation, which was a terrible investigation.

Gongsun Jingsheng is simply an underground emperor-like figure in Chang'an City, corrupt, relying on the strong to bully the weak, robbing the people's daughters, he has done everything you can think of, and he has done even the unthinkable.

The angry Liu Che directly ordered Gongsun Jingsheng to be taken into custody, and at the same time called Gongsun He to talk.

No one knew the content of the conversation, but Gongsun He's whole person instantly aged a lot, and the voice of counterattack disappeared in an instant.

And this scene scared the imperial historian Ni Kuan a lot, although Ni Kuan's son was not as excessive as Gongsun Jingsheng and Shi De, but the shrewd Ni Kuan still smelled a trace of unusual taste.

The emperor's series of actions, where is this grounding Liu Ponu?

It is clearly a false signal to the outside world, playing a trick to lure the snake out of the hole, Ni Kuan is also a member of the princelings, he knows that the emperor is doing this to pave the way for Liu Ponu and to purge the princelings in the Qing Dynasty.

And the solution is not nothing, you just need to go to Liu Ponu and bow your head, and express your willingness to switch to Liu Ponu, and all the problems will be solved at that time.

Others can do this, but Ni Kuan doesn't have the heart to do it.

is already old, and I don't have so much energy to do these things anymore, and I don't have many years to live when I'm old, so why do I have to let myself lose my old age?

He understood what the emperor meant, but he didn't want to do what the emperor wanted, so he made a middle choice.

resigned, returned to his hometown, and removed himself from the dispute with the crown prince.

In this way, he will retreat, and he will not become a help or threat to anyone, and the emperor will naturally not bother to deal with himself anymore.

And because of his resignation, the prince will not feel that he is retreating, but will feel that he is resigning to prove his determination, but he is just playing away.

But no matter what they think, after making this decision, as long as Liu Che nods and agrees, then Ni Kuan is the biggest winner, not only can he not offend anyone, but he can also keep his family.

"A prime minister, a royal doctor, and a servant, he really doesn't want to wait for a moment......" Liu Ponu shook his head helplessly.

The reason why the steam engine was not given up was because the steam engine was really easy to use, and until the internal combustion engine came out, the steam engine was the handle of the industry.

It's not that there is no alternative, it's just that Liu Ponu doesn't want to use it.

But now, seeing that the steam engine cannot be carried out due to the problem of sealing rubber, Liu Ponu has no more time to drill into the research.

Liu Che's series of actions outside were signaling to Liu Ponu that after the autumn, no matter whether the steam engine was successful or not, he would have to act according to the plan.

"The steam engine can't be stopped, but the speed can be slowed down a little, and then go find some more people to ask if there is any way to solve this problem!" Liu Ponu nodded, the atmosphere was set to this point, and it was absolutely impossible for him not to come forward.

Although Liu Che's movement is very large and the effect is also very good, but now the three positions of the prime minister, the imperial doctor and the imperial servant are all empty, and the imperial court has some problems because of this.

The methods were told to Liu Che, but he never acted, not because Liu Ponu had honey confidence, but because Liu Che was really waiting for Liu Ponu.

You can slow down, but you can't stop, this is Liu Ponu's bottom line.

At the same time, in order to cope with the shortage of labor, Liu Ponu had to compromise with reality.

It seems that the advanced and backward are not so important, the most important thing is to have something suitable for the current situation.

Therefore, Liu Ponu set his sights on the Stirling engine, which did not have such high requirements for tightness and relatively simple structure.

With the experience of making a steam engine, the next work is much less difficult.

The biggest disadvantage of the Stirling engine is that the heat loss is too fast, which will lead to insufficient power and affect efficiency, but these don't matter, what Liu Ponu wants is a walk-behind tractor that can drive the Quyuan plow to work steadily, for Liu Ponu at this stage, it is to find a way to make a bowl of noodles first, and then find a way to make meat when there are noodles.

Half a month later......

"And that worked?" Liu Qu and the others looked at the 'new steam engine' that had been running continuously for half an hour with disbelief on their faces.

For them now, the key factor in judging whether they have success is to see whether they leak or not.

Although the 'steam engine' in front of me also has air leaks, it is almost negligible compared to the white smoke leakage of the previous steam engine.

"Almost, build a body and try it!" Liu Ponu, who had been sad for a long time, couldn't help but show a smile on his face.

This time, he made a small experimental model first, and after success, he scaled it up according to the expected size, and the effect after enlargement looked good.

Next, Liu Ponu commanded everyone to start building the body, it didn't need to be complicated, a steel chassis was used to fix the engine on it, and the wooden wheels were made in advance, just install and fix it directly.

To solve the problem of the difference between the two wheels, Liu Ponu used the crankshaft, and the connecting rod from the engine was directly connected to the crankshaft, which was simple and rude, and cut off some middlemen to make the difference.

The body is much simpler, and it directly allows people to transform a carriage, and a connecting rod for connecting the front of the car is added below, and a two-finger-thick iron rod is inserted directly into it, which is very stable.

Liu Ponu had even imagined the picture of himself driving a walk-behind tractor and Liu Che sitting in the back of the car with a confused face......
