Gongsun He, who had an uncertain future, returned home with a gloomy face.

He didn't want to go to Jiaoxi, even though he could be treated preferentially by Liu Ju there.

But Gongsun He knew better what would happen after their gang gathered in Jiaoxi Kingdom?

But this is a matter that the emperor personally decides, and it is no longer up to him to decide whether to go or not.

At the same time, on the other side of Chang'an City.

The scientific research base that has been transferred to the Jianzhang Palace is very lively.

Although the old base was also very large, there was also a large area of farmland there, and the place that really belonged to them was not too big.

After coming here, it changed completely, taking advantage of Liu Che's absence in Chang'an, Liu Ponu waved his hand and directly knocked down a large area of Liu Che's royal garden.

These places are either used for study, work, or experimentation.

What made Liu Che's teeth itch even more was that after Liu Ponu's kid destroyed his hunting ground, he actually kept a part of it and put it inside the scientific research base, in order to let the so-called scientific researchers who stayed in it for entertainment.

Under Liu Ponu's heavy investment at any cost, the scale of the scientific research base has also ushered in a big explosion.

From only more than 1,000 people when they first moved here, it has now grown to more than 3,000 people, more than doubling in size, and the speed of expansion is still growing wildly.

At the current rate, it is expected that by the end of next year at the earliest, the number of formal scientific researchers here will exceed 10,000.

Although there is still a big gap between them and real scientific researchers, I have to admit that this group of people is already the strongest group of people in Dahan so far.

Of course, in addition to not developing according to Liu Ponu's expected ideas, the scientific research base still brought a lot of unexpected joy to Liu Ponu.

On the test site, a strange-looking car about five meters long and about two meters wide and high, wrapped in steel, was running fast with thick black smoke and whirring.

There is no need to test the data, and it can be seen with the naked eye that the speed of this car is far faster than the speed of any car now.

"Your Highness, the distance that this car can travel in a day is at least three hundred miles, but we have not been able to solve the problem of lighting at present, otherwise counting the night, even if the line of sight is blocked and cannot be driven too fast, it can travel at least four or five hundred miles in one day and one night." On the observation platform, a middle-aged man covered in black reported with pride.

The first generation of tractors could only travel a maximum of 130 or 40 miles a day, and later after improvement, the speed increased slightly, but not too much.

Although the engine equipped in the army has become larger, the power that can theoretically be provided has also increased a lot.

However, its dead weight has also increased a lot, plus the dead weight of the hull, and the need to load supplies and soldiers during the trial, so the actual speed has not increased much.

Therefore, the maximum travel distance of the current military version of the truck in a day is about 16 to 180 miles.

But even so, the speed of its march was more than three times that of the previous one, and if it caught up with the rapid march, it would be no pressure to break through the distance of 200 miles in a day.

In the past, breakthroughs were at the level of tens of miles, but this time they were directly improved by a hundred miles, what does this mean need to be said?

"Is the performance reliable?" Liu Ponu was not too surprised, the faster ones were not impossible to build, the problem was that it would not take long to break after they were made.

"There should be no problem, we have been testing for three days, and the engine will be inspected in detail every day, and the wear is indeed slightly more serious than before, but I think it is within an acceptable range, if it is calculated according to the frequency of the test, there will be a decrease in power after about a month, and some parts need to be replaced after two months, and a comprehensive overhaul may be required after three months." The middle-aged man said with a serious face.

"Not bad!" Hearing this data, Liu Ponu nodded with satisfaction, so he waved his hand and said arrogantly: "Reward 100,000 yuan, and all of them will be credited once!" ”

In Liu Ponu's place, if there is a mistake, it must be punished, and it doesn't matter who comes, even if the little mule makes a mistake, he will be punished according to it.

But meritorious service must also be rewarded, and it may not be absolutely fair, but Liu Ponu is still working hard in this direction.

The test data told Liu Ponu that the limit of this reconnaissance vehicle was two to three months.

But generally speaking, even in the fierce battlefield, in addition to the use of the external environment may be worse than here, the frequency of use of the vehicle or something, is definitely not comparable to the test site.

After all, the test here starts at dawn, and the speed is full in the middle, except for the refueling will stop, the rest needs to run until dark.

In fact, there is no need to refuel, after all, there are still some places in the carriage, which is a test site, so there is no need to carry too many personnel and equipment.

Often, two drivers go up with a day's rations, and the rest of the place is filled with coal, which is not enough to burn in two or three days.

Another reason why the Stirling engine is easy to build and use is because its construction is so simple.

That is to say, Liu Ponu has no way to solve the problem of wear and tear now, and more professional is to solve the problem of precision machining, and the manufactured parts can be used, but they are a little rough, which will aggravate the wear.

The most problematic area is the heating tubes, because this is where heat and friction occur.

The so-called replacement of some parts is to replace the seriously worn parts, and the overhaul is to replace all the heating pipes and the internal connecting rod pistons.

This set of operations is almost a third of the engine, which sounds like a big project, but the problem is to solve this problem, and the subsequent production process of integrated casting is changed to split casting.

As long as you have accessories in your hand, it doesn't even take two hours to change this thing.

"On behalf of all the people involved, thank you, Your Highness!" The middle-aged man trembled with excitement and excitement.

Money is not the most important thing here, although everyone likes it, and although the amount they can get is not too high, the basic support for the family is still enough.

If you want to be promoted here, you don't look at qualifications, but the number of meritorious services.

As long as the meritorious service is achieved five times, you can get an immediate promotion, even if there are no vacant positions for the time being, of course, it is impossible to have no vacant positions.

Liu Ponu's basic operation on this matter is that if the person who meets the promotion requirements does not have a suitable position, then let him form a separate team, and all the members are recruited from the newcomers.

It can not only be promoted, but also lead newcomers, and can also rapidly increase the base of scientific researchers, killing three birds with one stone.

Next, Liu Ponu learned about the driving mode of this armored reconnaissance vehicle, and then he was made a little crying and laughing.

This is really a knife cut on the buttocks, and the special mother opened her eyes.

"Your Highness, hehe, isn't this a reference to previous experience, installing two engines in one car can increase the speed to a certain extent, and the fuel consumption has not increased, so this time we have adopted the same method."

Later, I thought that in the past, when plowing the land, several people were needed to pull the plow, and it was the same for putting it on the engine. So we gave it a try, and it turned out that it worked, no, we installed four engines in this car, equipped with eight power pipes, and we only had one combustion chamber in mind, considering the fuel consumption. ”

"Devouring the Starry Sky: Signing in to Become a God"

"Of course, the fuel consumption is definitely more than before, after all, there are four engines here, and they are not next to each other, the only downside is that it will be a bit troublesome to check and repair......"
