"Okay, that's it for now. I have something to show you."

After saying that, Owen turned to look at Mapel, who immediately understood and took out a glass bottle filled with petroleum and handed it over.

After taking the bottle of oil, Owen showed it to the people present and asked, "Do you know what this is?"

"show me."

Tyrion asked for the bottle of oil, and the others gathered around to watch.

I saw Tyrion pulling out the cork of the bottle, stretching out his fingers to dip some of the black liquid in the bottle, rubbing it between his fingers, smelling it again, and then putting it into his mouth to taste.

"Pooh!"

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 can be ignited and emit thick black smoke."

"So you dwarves call it Shiqi."

Owen was not surprised that the dwarves knew this thing. After all, they had explored most of the Trans Mountain Range, so they knew the mountain range very well.

This bottle of oil was found east of the Red Sand Fortress, and it can be regarded as belonging to the Trans Mountain Range area. The dwarves should have known about it for a long time.

"Then what do you humans call it?" Tyrion put the cork back into the mouth of the glass bottle.

"People over at Red Sand Fortress call it black oil." Owen replied, "But its real name is oil."

"oil?"

Tyrion looked at the black liquid in the bottle and was keenly aware that this oil was definitely not simple. Owen would not use this thing to test everyone for no reason.

"Your Majesty, besides lighting and heating, does this oil have any other uses?"

"That's right."

Owen smiled slightly and explained to the people present: "After oil is processed, fuel can be obtained, and fuel is the most important fuel for internal combustion engines."

"Internal combustion engine? What is that? I remember His Majesty the King said that a steam engine is a type of external combustion engine. So what is the difference between an internal combustion engine and a steam engine?"

Hearing the unfamiliar terms, Tyrion asked a series of questions.

The other dwarf craftsmen and Gita were also curious about this, and they all looked at Owen, waiting for his further explanation.

"An internal combustion engine is a heat engine that burns fuel inside the machine and directly converts the heat energy released into power."

Owen first introduced the definition of an internal combustion engine, and then explained its differences and advantages from a steam engine.

Unlike an internal combustion engine, a steam engine requires external heating to boil the water in the boiler and turn it into steam to drive the piston in the pipe.

This process will inevitably cause a large loss of heat.

Therefore, there is no doubt 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, the steam engine must have a boiler, a large and bulky device, which consumes a lot of water and coal.

On the other hand, internal combustion engines can be compact in structure, light in weight, small in size, and consume less fuel.

Moreover, internal combustion engines are easy to use and operate, and their starting speed is much faster than steam engines.

After saying so much, everyone is still confused. After all, there are no real objects, so it is difficult for them to imagine.

"Is it really possible to burn fuel directly inside the machine and convert heat energy into kinetic energy?" Gita couldn't believe it.

"Don't worry."

Owen clapped his hands to attract everyone's attention.

"Since I introduced you to the internal combustion engine, I naturally have a new task to give you."

"New mission! Is there anything new we need to make?"

As soon as he heard about the mission, Tyrion immediately became energetic.

The other dwarf craftsmen also instantly became motivated and geared up to get ready for new work.

Every time a new machine is built, the dwarf craftsmen can benefit a lot from it, so they are looking forward to getting new design drawings from Owen.

Mapel took the initiative to come over and handed several sets of design drawings to Owen.

Owen distributed it to Gita and the dwarf craftsmen, and told them not to mix up different design drawings.

After getting the design drawings, the dwarf craftsmen quickly looked through them. The more they looked at them, the more excited they became. They could all be described as a collective orgasm.

"These……"

Tyrion looked at the drawings in the hands of several people one after another and found something in common.

“All cars?”

"Yes." Irving did not deny it. "I want you to build all cars equipped with internal combustion engines..."

Originally, the invention of the internal combustion engine led to the invention of the automobile.

The design drawings distributed can be divided into two categories: military and civilian.

Military vehicles have a significant feature, that is, they have strong off-road performance and can be used in various and even harsh environments.

The military vehicle drawings given by Owen include armored vehicles, artillery tractors, military motorcycles, military trucks and tanks, etc.

Let me explain the artillery tractor. This is a vehicle specially used to tow artillery, carry artillery, accompanying artillery ammunition and tools.

There is no doubt that the carrying capacity of this vehicle is definitely stronger than that of a horse-drawn carriage. With it, we can finally bid farewell to the history of carriages transporting artillery. In the future, the time required to transport artillery will be greatly shortened.

More importantly, due to the improvement in carrying capacity, Gita can be ordered to build artillery that is larger, has a longer range, and has stronger firepower.

In terms of civilian vehicles, there are trucks, cars, etc.

Owen asked Gita and the dwarf craftsmen to make military vehicles first, and civilian vehicles later.

After all, military vehicles have a hard reason to improve the mobility and combat effectiveness of the People's Army, but civilian vehicles are not yet popular and need to wait until the Morning Light Kingdom builds a relatively complete road network.

After listening to Owen's story, Gita boldly predicted: "After that, the carriage will disappear."

"really."

Owen agreed: "In terms of road transportation in the future, whether it is carrying people or goods, we will rely on cars, and horse-drawn carriages will become a thing of the past."

"Ahhhh——"

A dwarf craftsman suddenly wailed and said in disappointment: "Then all my efforts were in vain."

"In vain?" Owen looked at the dwarf craftsman, "Did you design something related to the car?"

"yes."

The dwarf craftsman said with a frustrated look: "Seeing how powerful the steam engine is, after research, I secretly designed a steam car that uses steam as power. I thought that the horse-drawn carriage would be replaced by my steam car in the future, but now it seems that

Your Majesty, your car will replace the horse-drawn carriage and my steam car."

After spending so much thought, only to find that the thing you designed is already out of date, it is really a shock.

"That's really a pity."

Owen could only comfort and encourage: "But it doesn't matter. You can continue to research different internal combustion engines. I believe you can design new things that change the world in the future."

"Thank you, Your Majesty the King, I will try my best." The dwarf craftsman was very frustrated now.

Originally, the development process from horse carriage to automobile had a steam automobile in the middle.

Reluctantly, Irving moved the internal combustion engine out in advance, directly erasing the steam automobile, a product of the intermediate development stage.

"Then, the task of building military vehicles will be left to you. I hope you can manufacture them as soon as possible." Irving finally said.
Chapter completed!
