Chapter 171 Fluid test

“It’s on fire…”

Before the announcer’s words fell, Renault felt the machine shook slightly, and at the same time a magical induction told him that behind the thick metal, violent burning was going on, and the hot flames filled the entire narrow space.

If it is an engine on the earth, the ignited oil and gas mixture will become a high-temperature and high-pressure gas, pushing the piston to move, and the force on the piston will be transmitted to the crankshaft through the connecting rod mechanism, and finally work to the outside world.

In this process, a large amount of high-temperature exhaust gas is inevitably discharged into the air, and a lot of heat energy is wasted.

Because of this, a heat engine like an engine always has an efficiency limit. No matter what egR technology or exhaust gas turbocharging, the improvement brought by it is quite limited.

But in another world, with the help of Rune Black technology, the expanding high-temperature gas will enter a huge rune cylinder with a diameter of nearly 60 cm and a length of more than 1.5 meters. Then, a magical change has occurred.

If you have see-through eyes and infrared vision, you will see an extremely fantastic scene.

The misty blue light intertwined with the flames to form a cluster of brilliant colors. Then the intensity of the infrared rays radiated by the gas began to decrease sharply. After passing through the rune cylinder, the mixed gas whose temperature was over 1400 degrees dropped to more than 60 degrees.

The heat was absorbed by the rune cylinder!

To be precise, it was absorbed by the large rune group [Thermal Power]!

What is the exhaust temperature of the earth’s diesel engine?

More than 400 degrees!

When working at full load, the temperature is even close to 600 degrees!

The gap is almost as high as 10 times, which shows how high the thermal efficiency of [Thermal Power] is.

So, what has the absorbed heat energy turned into?

Magic?

of course not!

The existence and generation mechanism of magical energy involves high-dimensional space. People in other worlds have studied for thousands of years, but they have not figured out what is going on.

No one knows how to convert other energy into magic energy.

In other words, magic energy can be converted into other energy, such as heat energy, kinetic energy, etc., but the reverse is not feasible.

Of course, the machine in front of Renault couldn’t do this, but with the help of the [First Law of Thermodynamics], the rune magicians found a new form of energy.

Renault calls it: Heat Demon Energy.

This is the real reason why this machine is named “Heat Demon Engine”.

Like magic energy, hot magic energy also exists in another dimension, but it has a very strange characteristic-it can drive the rune group [rotation] to generate kinetic energy.

However, it has a small shortcoming, that is, it does not exist for a long time, even if there is no external force interference, it will slowly dissipate into other dimensions of space.

Therefore, the energy transfer path of the thermal engine is like this: chemical energy → thermal energy → thermal energy → kinetic energy.

The conversion efficiency of each step is very high. The total efficiency exceeds 80%, and there is room for further improvement. I believe that with these diligent rune magicians, the thermal efficiency exceeds 85%, or even 90%. There is no big problem.

In addition, the Thermo engine has another advantage-low mechanical loss.

In a diesel engine on the earth, the thrust received by the piston needs to be transmitted to the connecting rod first, then to the crankshaft, and finally to external work. There is more or less a small amount of mechanical loss in each step.

That’s not all, don’t forget, there are also camshafts.

Part of the mechanical energy will be transmitted to the timing gear through a chain to drive the camshaft. During the rotation of the camshaft, the intake valve and exhaust valve will be constantly lifted up. These actions will cause mechanical loss. .

Even if the transmission efficiency of each step is as high as 99%, it adds up to a large number.

But the Heat Demon engine is different, its mechanical structure is extremely simple, the only movement mechanism is only a transmission shaft, and the mechanical loss is incredibly low.

This also brings another advantage. Simple structure means high reliability and low failure rate.

At this time, the excited voice of Mr. Broadcaster appeared as expected, “Everyone, we have detected a strong energy flow on the magic silver wire, which is more than ten times higher than a few days ago…

“Gosh, this is incredible…”

This sentence seemed to detonate something, and more and noisier voices appeared, and there was one thing in common in these voices-extremely excited.

“The large magic motive dedicated to the ship also moved…”

“The large gearbox is working…”

“The propeller turned…”

Accompanied by these sounds, there was the “click” of gear meshing, and the light whistling of the huge blades of the propeller across the air.

Renault involuntarily took a look at the location of the propeller. The huge iron block was also a part he picked up with his own eyes. It was nearly 3 meters in diameter and weighed more than 1.2 tons. It was a big guy.

The astute Seth immediately noticed Lord Lord’s movements, and turned his head to look at a rune magician: “Alvin, you go to replace Lord Lord and continue to drive the rune array…”

Then he bowed slightly to Renault: “Your Excellency, the next step is the fluid test of the propeller…”

Renault nodded and walked forward first, and the others immediately followed closely and flocked to Renault.

I have to say that human adaptability is amazingly high. If you are surrounded by people like this on Earth, Renault will definitely feel uncomfortable.

But since becoming the lord of the Hai Tide Islands, less than 2 months have passed. He has fully adapted to this kind of life and is used to always being the biggest focus of the crowd.

After passing the ship’s magic motive and large gearbox, Renault saw the propeller. It was fixed on a thick drive shaft. The huge blades kept rotating, and there was a strong wind around it. The young magician had to hold his hat with his hand, so as not to be blown away.

The speed of the propeller is more than 5 rpm, which sounds very fast, but for such a huge iron tuft, this speed is already quite fast.

In addition, its working environment is not air, it will be denser seawater, with very high resistance, and too fast speed will cause the propeller to be more stressed, and the metal will be more prone to fatigue.

Just below the propeller, a huge pool of about 20 meters in length has been dug out. The surface of the pool is covered with a layer of gray cement. At this moment, there is only one layer of shallow seawater in the pool.

Seth shouted: “Pour water into the pool…”

The two rune magicians standing at the end of the pool immediately pressed their right hands on the magic motive, and the two pumps connected to the magic motive were activated instantly, and the turbulent sea water flowed from the thick pipe into the pool, rushing The sound rang through the test workshop.

The power of the magic motive is more than 100 kilowatts, and the speed of filling water is quite fast. After a few minutes, the pool is filled with more than half.

Seth shouted again: “Switch the gearbox to neutral… Lower the propeller platform into the water and start the experiment…”

The rune magician standing next to the gearbox immediately pressed his palm on the rune disc on the surface of the gearbox, and after inputting a mental force, a small magic motive built-in turned and separated a pair of gears that meshed with each other.

This gearbox is also a product of Renault after it is opened. With the current manufacturing capacity of the Rune Research Institute, it is still impossible to get such a huge gearbox.

It has a total of 4 gears, except for neutral gears, the other 3 gears are low speed, medium speed, and high speed.

After the gearbox was adjusted to neutral, the speed of the propeller immediately slowed down, and at the same time a buzzing sound also rang, and the platform carrying the propeller began to slowly descend.

Ten seconds later, the propeller blades had stopped touching the water surface and gradually sank into it.

“Switch to 1st gear…”

Seth’s voice echoed in the empty workshop.

The propeller moved slightly, and the wide blades stirred the pool water continuously, and a visible water flowed out into the pool, hitting the opposite pool wall, and splashing 4 or 5 high waves.

The enthusiastic cheers rang out loudly.

As long as you are not an idiot, after seeing this scene, you will naturally understand how strong the water flow created by the propeller is.

This also shows how powerful the Heat Demon engine is.

At this time, Seth suddenly stroked his chest with his right hand, and saluted Renault extremely respectfully.

“Congratulations, great sir, you have changed the world again, I think the name of Odin will be passed on forever…”
