Engineer Cheol-woo Lee (15)
Woo woo woo woo woo woo-
The ITE engine continued to emit a quiet note.
“What is your current RPM?”
“It’s 100 now.”
Researcher Jung said while looking at the test instrument panel.
“Um…it started normally.”
It started, but I was not the only one worried. The test of the ITE engine started from now.
“It’s just that it started. Usually, in the first engine test, there are many cases where it doesn’t even start.”
“That’s right.”
Researcher Jung said, and team leader Seo retorted.
“Then, shall we begin the full-scale test soon? Raise the RPM to 1,000. Slowly.”
That is, the fuel valve is opened further to inject more fuel.
To put it a little easier, step on the accelerator.
“all right.”
Researcher Jeong increased the flow rate very little through the fuel valve mechanism.

As more fuel is added, the sound of the engine gets louder and louder. The crankshaft also started moving faster and faster.
“There is no problem yet. Fuel economy is excellent.”
Researcher Jeong was touching the fuel valve device, and Team Leader Seo was looking at various instrument panels.
“What is your estimated fuel economy now?”
“It’s 20.”
“Wow, 20? You haven’t even started the hybrid system yet.”
Researcher Jeong, who was next to him, said.
“This… must be an ITE engine. Actually, the thermal efficiency has gone up.”
“No hybrid system, 1 liter per 20 kilometers… that’s crazy. It’s an innovation.”
The engine was still running reliably.
“1,000 rpm reached.”
Team leader Seo, who was opening the fuel valve little by little, said.
“Let’s go up to 2,000.”
“Maybe I’m overdoing it the first time? Why don’t you analyze the experimental data a bit more and then test again?”
Chief Seo said.
“Let’s move on.”
“Um… yes. I understand.”
“Then open the valve more?”
“yes.”
Researcher Jeong continued to open the valve.
How far did you open the valve?
Heee-eee be-
A deafening sound came from the engine.
“…… What are you talking about? Isn’t it supposed to sound like this?”
“Stop! Stop!”
Team leader Seo exclaimed urgently.
Hearing that, I immediately pressed the emergency stop button.
Gyying- Gyyy-
When the emergency stop button was pressed, steam rose from the engine and gradually lost power.
“…”
“…”
“…”
We were all speechless.
“I expected too much from the beginning. It’s okay, Mr. Cheol-woo. You just have to find the cause and make it again.”
Team leader Seo was the first to speak after breaking the silence.
“Ah, it’s a pity. If it happened once, it could have remained a legend.”
Researcher Jeong also said that it was not a big deal.
“…”
But I couldn’t be bothered.
‘What was the problem?’
I don’t know the cause.
Obviously, by my calculations, the ITE engine should have worked perfectly. It is designed to operate normally, not only at 2,000 RPM, but also at 3,000 rpm to 6,000 rpm.
However, the ITE engine could not exceed 2,000 rpm.
“Mr. Cheol-woo. Why are you so depressed?”
Researcher Jung said, but I didn’t hear.
‘why? Why?’
It was just that thought. All calculations would have been perfect.
Displacement, air density, outside air temperature, outside air pressure, volumetric efficiency, energy lost, amount of fuel, specific fuel consumption rate, fuel consumption rate, flow, air-fuel ratio, etc.
I thought I had calculated everything without missing anything.
Of course, there were values for estimation. temperature value, air flow rate, etc. However, I calculated within the margin of error and thought there would be no problem.
‘Is it an AA system problem?’
If there is an innovation in the ITE engine, it is the introduction of the AA system, and the rotational energy of the engine is driven and generated at the same time through the TT gear.
The hybrid system was not used, and even if it was used, the performance of the TT gear was verified. No problem.
Then again, it’s an AA system.
I went straight to the engine and tried to rip the AA system.
“Oh, it’s hot!”
As soon as I put my hand on the engine to disassemble the AA system, I was burned.
“Mr. Cheol-woo, are you okay?”
“No, sir. What would you do if you touched a heated engine with your bare hands without cooling it down?”
“…”
It was common sense. If the engine is running, there has been combustion, which means that the temperature of the engine has risen.
Even if you don’t think it’s hard, the engine gets hot when you get in the car.
I hadn’t thought of that simple thing.
“Why are you so crazy?”
“Cheolwoo teacher?”
“under…….”
He let out a deep sigh.
‘Everything went well at once until now? why?’
There hasn’t been a single minor failure so far. All of the engineering, including programs, hacks, and mechanisms, was in my calculations, and it was realized as the calculations.
But not this time.
I obviously calculated everything, but it didn’t go the way I wanted.
“Why are you so depressed? You can check and improve again.”
Researcher Jung said.
“Well… I’m not motivated.”
There is no desire whatsoever.
because it failed
Before my freshman year of college, I failed countless times. But at some point, I was successful. It must have been since the 10th anniversary of my grandfather’s ancestral rites.
Are you too familiar with success? I didn’t know that failing would be so hard.
“I… I’ll go in first.”
“…… Yes. It’s late today, so go in and get some rest.”
“It’s no big deal. Don’t worry too much.”
I felt like I had to go back home.
* * *
The underworld across the Samdocheon.
“Oops, tsk tsk tsk.”
“Cheolwoo guy finally failed?”
Cheol-woo’s grandfather and Min-seok’s grandfather were looking in the mirror of the underworld.
“Hey, do you like it because Cheol-woo failed? Do you like it?”
“No, it’s not good. It worked so well, so the medicine went up a little.”
“Your grandson, Min-seok, must succeed when our Cheol-woo succeeds. Do you know?”
“Ah~ That’s right, the older brother just said something. You’re strict.”
Cheol-woo’s grandfather was not alone in his worries.
“Why, what are you so worried about? Failure is something anyone can do.”
“Didn’t I buy a scroll of gift giving to Yeomra? There were a few things to keep in mind.”
“Notes? Is there anything like that?”
“Well, it’s trivial stuff, how long does it last, who can use it for, etc.”
“But what are you worried about?”
“There was such a word among the precautions, ‘If a person with genius talent fails, he will fall into a slump, so be careful.'”
“Isn’t it obvious? Why, even soccer and baseball players sometimes perform poorly and then fall into a slump. People who have always been successful try to fail and fall into a slump.”
In a way, it was natural.
Cheol-woo had been consistently successful. There was never a single failure. But what if you were incredibly confident and then failed?
The shock will not be the only one.
“I’ll have to overcome that slump somehow.”
“No, but I’m curious. Why do you fail even though you have such genius abilities? Isn’t Enma cheated?”
“Um… that’s not it.”
“then?”
“That was also mentioned in the notes, but as far as genius talent goes, they say it’s the peak of the present age.”
“The high point of the present age?”
“Uh, I can’t have a talent that goes beyond the limits of the era in which Cheol-woo lives.”
“Well, so the current gasoline engine thermal efficiency is 25%, right? That’s the limit of the current era.”
Cheol-woo’s grandfather and Min-seok’s grandfather studied a lot while watching Cheol-woo.
“That’s right, it’s not going well because I’m trying to create something that goes beyond that limit.”
“No, so you’re saying he can’t complete the ITE engine he’s making?”
“It’s up to you to withdraw.”
“What does that mean again?”
“I don’t know if I explained it. Admiral Yi Sun-sin and King Sejong wore the same scroll.”
“I did.”
“How could those great men protect and stabilize the country with ideas that transcend the times?”
“Um… I don’t know.”
“Obviously, scrolls of talent cycles are helpful. But to create achievements that exceed the limits of the present age, you must put in enough will and effort.”
“Hah? Cheol-woo says he’s grown up, but is that possible?”
Minseok’s grandfather also started to get anxious.
“I’m worried. Cheol-woo should do well.
“Um… you should do well.”
“Can I give you some advice in my dreams?”
“Does it mean anything?”
“There won’t be.”
“By the way, if the real Cheol-woo completes the ITE engine properly, then what will happen?”
“Well, what happens. It’s to leave a great achievement.”
“A great achievement.”
to increase thermal efficiency.
It was one of the greatest achievements in human history.

A lot of time has passed since the first test of the ITE engine.
In conclusion, the ITE engine is still in the testing phase. It’s still not going over 2,000rpm, and I still can’t figure out what the cause is.
‘Is it my limit?’
I couldn’t help but think so.
‘Have I been able to come this far just because of luck?’
I don’t think so, but it keeps lingering in my head.
‘What is the cause? The theory is perfect. Why?’
In fact, it was a long time ago that I thought about it.
After the failure, I did a little research here and there to find the cause of the failure for several months. However, the result is a failure.
Can’t even find the cause.
“Brother, what are you doing. Always here, go to class.”
Hyejeong came to talk.
“Ugh… I’ll go.”
“No, where did Cheol-woo oppa go?”
“Hyejeong, I’m sorry.”
“What are you sorry about?”
“I just wanted to avenge your grandmother, but everything went wrong.”
From noble mtl dot com
“No, what the hell does that matter? I’d rather not?”
“… Anyway, I’m sorry.”
“Ugh.”
Someone entered the club room.
“Cheolwootsu~!”
Changsoo always greeted me brightly.
“Oh, here you go.”
“Ah, this guy is doing this again. What’s the point of failing once? Just keep trying.”
challenge?
I kept doing it. After that, I continued to search for the cause. However, the cause has not been found yet.
It’s been about 3 months since I can’t even find the cause.
I thought there was virtually no way.
“Changsu, I’m sorry to your father.”
“Eh? Father suddenly?”
“Oh, no…”
He also wanted to avenge Changsu’s father’s humiliation. But everything has become meaningless.
Another person entered the club room.
“Hey Cheolwoo. International patents have been registered this time. Technologies related to TT gears and 6-axis milling machines.”
“Good.”
“Ha, this guy, he’s still doing this. Do you know how great it is to be registered as an international patent? Rejoice a little more.”
“What do you do if you’re happy? After all, I couldn’t make an ITE engine.”
“Does it matter?”
“Then it’s important. In fact, I bet my all on it.”
“What bullsh*t. What did you bet? Did you bet more than time? And what’s important is the result. The process is important.”
Minseok said with a temper.
“What’s important is the process. What’s important is the result.”
“No, the process is also important. You learned a lot while studying the engine. Do you know how blood and flesh it becomes?”
“…”
As Minseok said, I definitely learned a lot.
“Now, you can just make one tolerable engine.”
“That’s right.”
“Immediately go back to Hyeonseong’s lab. Then tell me. I’ll do it again.”
“Will it make a difference if I do it again?”
“Did you do your best?”
best… … .
“I don’t know.”
“Then you didn’t do your best. If you fail once, you’ll get frustrated and stop looking for the cause.”
“…”
How could Minseok know me so well?
“Go and do your best. If that doesn’t work, there’s nothing you can do. Your ability is that far. And accept it, your ability. Because that’s great enough.”
Suddenly, something hit my head.
‘I am… … . you were dodging I’m afraid they’ll notice the limits of my abilities.’
I was afraid.
If I know my limits, that’s where I end up.
I realized after hearing Minseok’s words.
‘There is no need to be afraid.’
I did my best, but it’s beyond my ability to fail. Not doing your best, and doing this… … .
okay.
just a coward
“……Thank you, Minseok. I’ll go again.”
