"Ignite." With Yang Heng's order, several workers began their work, three months after the boiler officially reached its practical level.

Although Yang Heng did some other things in the middle, the production of the steam engine components here had no impact, because these things were already done by professionals. Yang Heng would not be better than them in any case, especially those lathe workers. They are really working hard to learn, and they are now able to maximize the ability emitted by the water truck.

But that's true, the power of these water trucks is still very poor and the work is very slow, but this also makes these lathe workers more concerned about the parts they process themselves. If a part is processed, it will take a few days or even more than ten days. It is just a small part and it cannot be processed in a very short time.

Therefore, during this day, half of the time was wasted on measuring the size of the parts, but such precise testing allowed defective products and even waste products to be produced directly. Therefore, the first test steam engine was considered to have left the factory.

"You all have a good idea. This mark, yes, is these two marks. You must aim them when the machine is shut down. If it is not correct, it may not work properly."

The steam engine developed by Yang Heng is the simplest type of steam engine, but he doesn't remember the name of his previous life. Moreover, he has also made improvements, that is, converting the crankshaft into an energy that drives the flywheel to a power that drives the rotation of the flywheel.

"Chi..." "Boss, the air pressure is coming." Several workers at work shouted loudly, "Open the valve." "Chi..." With a dull sound, I saw a stream of steam spewing out from the side. Then, Gaden, Gaden's voice came out, but this was not the sound of a train, it was the sound of the crankshaft driving the flywheel to rotate, and then the sound became faster and faster.

"Close the valve and test to adjust the speed." At this time, you can only use a clamor and even a gesture.

At this time, the workers next to the boiler were sweating profusely. One was summer, and the other was that the steam was really hot. It seemed that the reuse of the steam, even the remote discharge of the steam, was also a problem. Either add a fan to the side of the flywheel to cool down the workers.

After more than an hour of testing, the steam engine was officially successful, but it is still a problem. However, Yang Heng felt that the power was still very sufficient. After modification, it can be used to drive the lathe and conduct durability tests. However, if you use this steam engine to get on the car, Yang Heng felt that it would not be enough. The power should not be very sufficient. Should the most suitable one be a reciprocating steam engine, or even a steam engine that uses steam multiple times.

And this first unit can only be used to test the durability of components, and the durability of lubricating oil. You must know that this is the first time lubricating oil is used on high-temperature and high-speed machinery.

Speaking of lubricating oil, this is also a by-product. It is a by-product developed by Taoist priests in the mountains when they were developing Eucommia ulmoides. They originally thought it was useless, but they just created a few things to put them there. They were poured, but they were reluctant to let them go, but they didn't fall down. Inadvertently, Yang Heng discovered this thing.

"Master, what are you doing? It's black?" "Go back to the home, this is something we developed some time ago, but it feels slippery, but it has no practical use. I'm thinking about whether it's overturned." "So, this thing doesn't burn your hands." Yang Heng was very careful. If he didn't know anything, he would generally not do anything. You must know that there are some immature chemical experiments, and maybe there are some burning things in it.

"Don't burn your hands, just pinching them with your fingers and it feels smooth." He felt relieved when he heard this. He dipped a little black liquid with his fingers. "This is lubricating oil, do you have any records?" Yang Heng was shocked. These Taoist priests tried something and actually made all the lubricating oil. How effective should it be used on horse-drawn carriages and even the axles of water trucks. The lubricating oil he used in the past was vegetable oil. This vegetable oil was not a particularly good lubricating oil, but was just slightly stronger than nothing. Some parts were still seriously damaged. Yang Heng had been thinking about how to make this lubricating oil, but in his mind, he couldn't even think of any idea. This is not a professional, and he really doesn't know how to make the manufacturing principle. He just knew that this was a kind of thing extracted from oil, and even had other chemical effects. Unexpectedly, it was made inadvertently in the hands of these Taoist priests.

"Owner, this is a bit troublesome. Although we have records, we actually forgot which day it was made." "Don't worry, remember, and then do the tests for those days again. Wouldn't you find the formula? Also, no matter whether you make useful or useless things in the future, label them for us to find them." This is the history of the discovery of this lubricant, but now the Taoist priests have something to do, and Yang Heng would not believe that this lubricant will be durable in high-temperature machines, so it must be re-studied. However, with this foundation, it is very simple to study again. Moreover, Yang Heng believes that this black thing will definitely turn into a clear thing, or a little bit of other colors, rather than a black color.

Although the first experimental machine has been made, some problems have not been solved yet. The first is to solve the problem of machine cooling. You must know that when the temperature is high, various problems will also arise. However, Yang Heng no longer needs to be responsible for it himself. He has left all of them to his hands to do it. He even has some theoretical matters to professionals to solve. They are good at math. They not only need to calculate some calculation formulas, but also write some theoretical things. Of course, these things need to be discussed by Yang Heng, and even disassemble and assemble the machine a few more times. In this way, they can truly understand this principle.

Another thing is to transfer the power of the steam engine to the lathe. So, on the other side of the steam engine, a flywheel is added again, and a pulley is added to the flywheel. This pulley is used to drive the lathe. Moreover, an elastic pulley is installed on the lathe. That is to say, after the pulley is tightened, the lathe will rotate. If the pulley is relaxed, the belt will be loosened, and the lathe can directly brake the car.

The test model is troublesome. The first thing to do is explosion-proof. In this way, there is a thick stone wall between the lathe and the steam engine. The workers responsible for the steam engine are also working remotely. Similarly, the coal delivery and remote control valves have been lengthened or even modified. This is also for the sake of safety. However, once the test is successful, it will not be so troublesome. The lathe and steam engine are close to each other, and the operation will be directly changed to two people. One is to operate the steam engine and the other is to operate the lathe. In this way, it is much simpler in controlling the speed and some other aspects.

However, what Yang Heng wanted to do most was to use a steam engine to generate electricity. Once the steam engine was used to generate electricity, the lathe could be driven by a less-sounding motor. Then, no one would come from every family. It can be said that a power plant can be used to supply power in Chang'an City, and even heating may be provided together.

"Owner, this lathe driven by a new machine is very powerful. The parts that were made in one day before were made, but now they don't need to be made in half a day, but that's it, the noise is too loud."

Yes, the noise is too loud. When they talk to Yang Heng, they always yell, and even after get off work, they talk loudly to others, which has affected their ears.

"Don't worry, once the steam engine is tested successfully, the noise-free motor will be used as power immediately." Yang Heng said to him loudly regardless of whether the worker understood or did not understand. (To be continued...)
