"Alright, that's the end of it, I have something to show you here."
With that, Ou turned his head to look at Marpel, who immediately understood, took out a glass bottle containing oil and handed it over.Taking the bottle of oil, Ou showed it to the people present and asked, "Do you know what this thing is?"
”"Show me."
Tilion brought the bottle of oil, and the others gathered around to watch.Tilion pulled out the cork of the bottle, stretched out his finger and dipped the black liquid in the bottle, rubbed it between his fingers, sniffed it again, and then put it in his mouth and tasted it."
Phew!"
He decisively spit out the black liquid that had just been put into his mouth and said, "Isn't this stone paint?"
I remember it could be ignited, emitting thick black smoke. ”"So you dwarves call it stone paint."
Ou wasn't surprised that the dwarves knew about it, after all, they had explored most of the Transverse Mountains, so they knew the mountains very well.And this bottle of oil was found in the east of the Red Sand Fortress, which can be regarded as something that belongs to the Trans-Mountain Range area, and the dwarves should have known about it for a long time."
And what do you humans call it?"
Tilion stuffed the cork back into the rim of the glass bottle."
The people over there at the Red Sand Fortress call it Black Oil."
Ou replied, "But its real name is oil." ”"Oil?"
Tilion looked at the black liquid in the bottle, and keenly sensed that this oil must not be simple, and Ou Cai would not use this thing to test everyone for no reason."
Your Majesty, is there any other use for this oil than for lighting and heating?""
That's right."
Ou smiled slightly and explained to the people present: "Oil can be processed to obtain fuel oil, and fuel oil is the most important fuel for internal combustion engines. ”"Internal combustion engines?
What's that?
I remember that Your Majesty said that the steam engine is a type of external combustion engine, so what is the difference between the internal combustion engine and the steam engine?
”Hearing an unfamiliar term, Tilion threw out a series of questions.The other Dwarven Craftsmen and Geeta were also curious, and they all looked at Ou in unison, waiting for him to explain further."
An internal combustion engine is a heat engine that burns fuel inside the machine and converts the heat energy released from it directly into power."
Ou first introduced the definition of the internal combustion engine, and then explained its differences and advantages from the steam engine.Unlike internal combustion engines, steam engines need to be heated externally, boiling the water in the boiler so that it turns into steam and pushes the pistons in the pipes.This process inevitably results in a large loss of heat.Therefore, it is undisputed that the thermal efficiency of a steam engine is lower than that of an internal combustion engine that can directly convert heat energy into power.Not only that, but the steam engine had to have a boiler, a large and bulky device, which consumed a lot of water and coal.On the other hand, the internal combustion engine can be compact, lightweight, small in size, and less fuel consumption.Moreover, the internal combustion engine is easy to use and operate, and the starting speed is much faster than that of the steam engine.After saying so much, everyone is still confused, after all, there is not even a physical object, and it is difficult for them to imagine it."
Is it really possible to have the fuel burned directly inside the machine and the thermal energy converted into kinetic energy?"
Geeta couldn't believe it."
Don't worry."
Ou clapped his hands to attract everyone's attention."
Since I have introduced you to the internal combustion engine, it is natural that I have a new task for you.""
New mission!
And what is there to make in the new world?
”As soon as he heard about the mission, Tilion immediately came to his senses.The other dwarven craftsmen were also instantly motivated, and they all rubbed their fists and prepared to devote themselves to the new work.Every time a new machine is built, the Dwarven Artisans benefit greatly from it, so they are looking forward to getting new design drawings from Ou.Marpel took the initiative to come over and handed over several sets of design drawings to Ou.Ou distributes it to Geeta and the Dwarven Craftsmen, telling them not to confuse the different blueprints.After getting the design drawings, the dwarven craftsmen hurriedly looked through them, and the more they looked, the more excited they became, and they could be described as collective orgasms."
These" Tilion looked at the drawings in the hands of several people in succession and found a common denominator."
It's all cars?""
Yes."
Ou does not deny that "I want you to build all cars equipped with internal combustion engines" Originally, the invention of the internal combustion engine prompted the invention of automobiles.The design drawings that have been distributed can be divided into two categories: military and civilian.Military vehicles have a significant feature, that is, strong off-road performance, can be used in a variety of different and even harsh environments.The drawings of military vehicles in Europe include armored vehicles, artillery tractors, military motorcycles, military trucks and tanks.Explain the artillery tractor, which is a vehicle dedicated to towing artillery and transporting artillery, ammunition and tools.There is no doubt that the carrying capacity of the car is certainly stronger than that of the horse-drawn carriage, and with it, it will finally be able to say goodbye to the history of transporting artillery in horse-drawn carriages, and the time required to transport artillery in the future will be greatly reduced.What's more, thanks to the increased carrying capacity, Geeta could be instructed to create larger, longer-range, and more powerful guns.In terms of civilian vehicles, there are trucks and cars.Eurangita and the dwarven craftsmen gave priority to the construction of military vehicles, and civilian vehicles later.After all, military vehicles have a hard reason to improve the mobility and combat effectiveness of the People's Army, and civilian vehicles are not convenient to popularize for the time being, so we need to wait for the Chenguang Kingdom to build a relatively complete highway network.After listening to Ou's story, Geeta boldly predicted: "After that, the carriage will disappear." ”"Indeed."
Ou agreed: "In the future, in terms of road transportation, whether it is to carry people or goods, it will be necessary to rely on cars, and horse-drawn carriages will become a thing of the past. ”"Ahhh ”"In vain?"
Ou looked at the dwarven craftsman, "Did you design something about cars?"
”"yes."
The dwarven craftsman said with a look of dismay, "Seeing that the steam engine was so powerful, after research, I secretly designed a steam car that used steam as power.I thought that in the future the carriage would be replaced by my steam car, but now it seems that your horse, Your Majesty, will replace the carriage and my steam car. ”After putting so much effort into it, only to find out that what you designed is outdated, it's really devastating."
That's a pity."
Ou Ye could only comfort and encourage: "But it doesn't matter, you can continue to do research on different internal combustion engines, and I believe that you can design new things that will change the world in the future." ”"Your Majesty, I will do my best."
The dwarven craftsman was frustrated right now.Originally, in the development of horse-drawn carriages to automobiles, there was a steam car in the middle.Helplessly, Ou moved out the internal combustion engine in advance, and directly erased the product of the intermediate development stage of the steam car."
Then, the task of building a military vehicle is entrusted to you, and I hope you will build it as soon as possible."
Ou finally said."
Yes, Your Majesty."
Everyone responded in unison, "Promise to complete the task you have delivered." ”
