Thousands of sparks

Chapter 29 The Steam Knight
The conflict with Harold is like a drama that has completely ended before reaching a climax.It is good to be able to avoid the situation of becoming a prisoner at the age of ten, but this somewhat makes Du Sande feel a little "hanging breath".

Not comfortable enough.

Fortunately, other things are progressing very well, even a little too smoothly.This made Du Sande suddenly feel that life seemed to be smooth sailing again.

The improvement of the internal combustion engine has entered the final stage. The combination of Polina's hard work day and night in the workshop and Du Sande's knowledge of cars in her previous life quickly showed results.

Polina's gas engine began to quickly show the potential to surpass the external combustion engine.With the blessing of water cooling and heat dissipation, the improved gas machine can not only ignite smoothly, but also complete the operation for more than half a day without external force intervention.

The working parts of the steam engine are exposed, and a large number of steps require human intervention - such as adding fuel, such as manually releasing the steam in the cabin to control the pressure, such as lubricating the pistons, connecting rods and other moving parts.

For a steam engine to run stably for a long time, it needs the continuous cooperation of at least one great technician, at least one technician and a fireman.The Grand Technician is in charge of general control, the stoker controls the temperature and air pressure levels in the furnace, and the Technician is responsible for lubricating moving parts or working with the Grand Technician to troubleshoot individual valves and piping.In short, the steam engine has many advantages, but "saving trouble" has never been its specialty.

The improved steam boilers of the empire have greatly improved the size of the pressure vessel and the degree of pressure resistance. The pinnacle of the steam engine, the steam carriage, does not even need the presence of a stoker to operate at all times, but it still requires at least one A technician performs maintenance on the steam horse three times a day.

The hollows on the body of the steam horse not only meet the requirements of the steam horse's movement and stretching, but also facilitate the technicians to repair the steam engine wrapped in the horse.

But the internal combustion engine is different - its basic principle inherently requires the machine to be maintenance-free for a certain period of time due to its construction.

No one can lubricate moving parts with an oil can while the internal combustion engine is running, and it is impossible to adjust the speed of the piston through the stoker.Therefore, sufficient design must be done at the beginning, so that the goal of "maintenance-free" can be achieved.

"Other problems are easy to solve, but the heat dissipation is not easy to deal with now." Polina reported her current research progress to Dusand in class, and began to hope that Dusand could get out of her mind. Some new ideas to help her solve the puzzle.

"How did you manage to dissipate heat?" Dusand didn't expect that Polina hadn't solved the problem of heat dissipation. "If there is no heat dissipation, wouldn't the piston melt down soon?"

"In the previous demonstration machine, I designed a water circuit to dissipate heat with continuous flowing water." Polina frowned and said, "But in the last experiment, the heat dissipation system couldn't keep the temperature down and it melted down... Can’t it just be used in rivers or lakes all the time?”

The steam engine does not need to dissipate heat, or its working principle is to use the process of "heating-dissipation".This is not the case with internal combustion engines. If the heat generated by combustion is not dissipated as soon as possible, the piston will soon cause excessive wear and malfunction due to thermal expansion.

Du Sande rolled his eyes, "The situation last time can't be used as a reference. It was a combustion process with added oxygen content, and the combustion will be much more intense. The heat dissipation system... I think it may be solved without a sewer."

As a student of pharmacy in his previous life, Dusand certainly couldn't know much about internal combustion engines—that's why he decided to use half of his profits to be the only person in the world who understands internal combustion engines.

But he still played with mobile phones and computers.Moreover, as a male college student with a lot of spare time, Du Sande is quite familiar with the heat dissipation of electronic equipment.

Traditionally, there are three ways to dissipate heat for electronic devices—passive cooling, air cooling, and water cooling.Strictly speaking, passive heat dissipation can also be considered as a type of air cooling, but in order to distinguish the types of heat dissipation, it is temporarily divided into three categories here-putting a carrot on the CPU is also a type of passive heat dissipation. Of course, this is of no reference significance .

Passive heat dissipation is suitable for devices with stable and extremely small heat generation, and internal combustion engines cannot be used as a reference.But air cooling and water cooling are actually quite good solutions.

Air-cooled heat dissipation itself is a main technical route for old-fashioned automobile engine heat dissipation.Wasn't the Porsche 911 back then an air-cooled engine?

"However, there are already water channels... Then we only need to design a heat dissipation system." Dusande thought for a while and said, "The solution is ready-made, and it is not very complicated, but the heat dissipation fluid may need to be specially selected... …I’ll start by drawing a sketch of the plan.”

Lorraine is wrestling with linear equations in one unknown, and Paulina, who is waiting for the drawing, occasionally comes to answer some questions about her "homework".On the other hand, Dusand began to draw a rough schematic diagram.

Dusand, who was considering what graphics to use to represent the water pump, suddenly felt a sense of comfort and relaxation.

This kind of life is pretty good—make money by inventing inventions, and then train the little loli to become a rich and powerful nobleman.

It's best not to go to a place like the Heraldry Management Office.

"We have to go to the coat of arms management office again later." In the afternoon political affairs class, Mr. Morris said to Dusand with a smile on his face, "In the next year, the two of us will often discuss with the coat of arms. When dealing with the management office, you need to familiarize yourself with the relevant procedures first.”

Dusande opened his mouth wide and didn't say a word for a long time.

"I know what you want to ask." Mr. Morris said with a smile, "Why do we need to deal with this kind of secret service?"

Closing his open mouth for a long time, Du Sande nodded vigorously.

"I am now the chief private secretary of the madam, and you are my student, the only son of the madam, and the chief private secretary of the future parliamentarian." Morris showed a helpless smile to Dusand, "Since the day before yesterday, the coat of arms The management office has just issued a notice, requiring the chief private secretary of every member of parliament who is preparing to run for office to file for the record."

Du Sande was stunned for a long time before saying, "But... I was planning to go to the industrial area today..."

"It won't take too long." Mr. Morris explained, "Aika doesn't have so many people to investigate and review all the private secretaries."

Aika is a transliteration of the abbreviation of the Heraldry Management Office, and it sounds a bit like the "Cheka" back then.

Dusand frowned and struggled for a while, then reluctantly agreed to the request.

When you come back, you must light a brazier again, and cross it back and forth 21 times [-] times.

The office building of the Newsail Arms Management Office has never been so lively in 170 years.

Chief secretaries from various places in Newsail poured into the coat of arms management office like fleeing refugees. With their mud-stained boots, they trampled the luxurious office hall into farmland as if it had just been attacked by cattle. .The chief secretaries, waving documents in their hands and yelling loudly in voices with different accents, looked like they were arguing, or preparing for a gang fight.

Morris took Dusand around the door, and walked to the side door with ease.

"The next step is up to you." Morris knocked on the wooden door, then took a step back, "Remember, follow what I just taught you."

Dusande glanced at Morris in disbelief, and then saw the wooden door jerk open, and an extremely tall "knight" wearing armor and carrying steam on his back appeared in front of him.

It is said to be a "knight", but it actually looks more like a monster.This monster is three meters tall, and its whole body is covered with armor made of rivets and metal plates.The huge helmet is connected directly to the shoulders, without a neck.And the part of the helmet looks like a huge crow.

The long, slightly curved beak extends downwards, and the eyes are covered by a hollowed-out honeycomb-shaped armor plate. Behind the armor plate are hidden gears and screws—they moved a few times quickly and issued a burst of "click" There is a sound, and then the black lens is switched to transparent.

Behind the transparent lenses, a pair of brown eyes were revealed.

"Uh... my name is Dusande." Dusande blinked, and after confirming that the pair of brown glasses belonged to humans, he said tentatively, "I'm here to have afternoon tea with Mr. Bourne."

"Please wait a moment." A large cloud of steam rose from behind the knight, and he stepped forward and turned around, leaving behind a sentence of "I'll check it out."

The tall figure was completely covered by the steam, and Dusand took two steps back to avoid the direct attack of the steam.Then asked Morris, "What is that...?"

"Oh, by the way, you haven't seen it." Morris nodded. "That's the pride of the Royal Army. They call it the Steam Knight."

"Cool!" Du Sande became interested immediately.What man isn't interested in giant humanoid machines?And this style of painting is really cool-a large black robot with a crow helmet, armor plates and rivets all over the body, and a large amount of steam will suddenly be ejected from the back as it moves... Every element seems to be Shouting "violent" and "handsome".

"You like this type?" Morris's smile became more mysterious, "Then you must not tell the colonel. The navy and the army have always looked down on each other. If Mr. Colonel knows that you are interested in the army's toys , the only response may be to make you carry weights and run cross-country for a day."

Du Sande didn't care that he might be ordered to run by his father, he asked very excitedly, "Mr. Morris, is there a way to buy this thing?"

"Want to play?" Morris grinned, "I'm sorry, my good lord. The army is just this treasure, and they take it very seriously. What's more, this kind of thing has no civilian value and meaning at all except for combat. So I'm sorry, but if you want to sit in and have fun, the only way is to join the army."
