Engineer Cheol-woo Lee (14)
It’s already been two weeks since I started to acquire Hyeonseong’s technical skills, and during that time, I learned a lot while studying Hyeonseong’s engine design.
‘Wow, that’s great, that’s great. If I had started making engines by myself just because I was a passenger… … . Just imagining it is terrifying.’
admired inwardly.
If I had tried to solve and create all these problems by myself… … . Well, it probably took at least two years.
Two months for valve input and output, two months for fuel intake design, and so on.
I thought it was good that I worked with Hyunsung.
‘To destroy a Toyo car, I need the power of a wise star.’
In addition, when will I make an engine by myself and commercialize it and raise the brand image? It is an achievement that CEO Hyeon-seong also took a lifetime to achieve.
‘Then let’s start soon.’
The time has come to create a gasoline engine with increased thermal efficiency, which has been thought of so far.
“Chief Seo, Researcher Jung.”
“yes.”
“yes?”
“I think it’s time to make it soon. Project name increase thermal efficiency. ITE project for short.”
“……Do you really make it?”
“Yes. Have I lied all this time? Let’s start today.”
From noble mtl dot com
“It’s finally starting. I’m looking forward to it.”
“Please do it.”
“Can you take a look at the engine I designed first?”
While studying Hyeonseong’s engine, he gave them the blueprint of the engine he had designed in his spare time.
“…?”
“Huh? What the hell is this?”
Team leader Seo looked at it, but didn’t say anything, and Researcher Jeong didn’t seem to understand the blueprint I gave him.
“First of all, fuel intake must be changed to a PULL-IN method, not a PULL-DOWN method.”
“Yes? Why?”
“hmm…….”
Researcher Jeong refuted, and Team Leader Seo seemed to be thinking.
The PULL-DOWN method was to inject fuel into the engine and inject fuel again after all combustion was completed, and the PULL-IN method was to inject fuel again before complete combustion of the fuel was completed.
And the PULL-IN method, as far as I know, was a method that disappeared a long time ago due to low efficiency.
“The PULL-IN method was made in the 70’s. Are you saying you’re adopting it again?”
Right away, Researcher Jeong walked away.
“Yes. The PULL-IN method does not have only disadvantages. By continuously injecting fuel, intake energy can be reduced.”
“No, I know that. That’s against the four-stroke engine. Without suction, how does it compress, explode, and even exhaust? When there’s no suction, it’s just burning. It’s no different from a steam engine.”
A steam engine using steam, it is not a 4-stroke. It simply compresses steam with thermal energy to produce power.
That is, it is a legacy of the past.
Steam engines are rare these days.
“How are you going to turn the crankshaft? Only with combustion energy. No, is the crankshaft going in in the first place? It’s not a 4-stroke engine.”
“Yes. Go in.”
“No…… Mr. Cheolwoo. However, I don’t think this is the case. It completely breaks the existing common sense.”
Researcher Jung continued to say that it was nonsense.
“Yes. That’s right. It breaks the conventional wisdom. You know the jet engine, right?”
“Yes. I know.”
“Is it the same as a gasoline engine?”
“Of course it’s different. A jet engine is fundamentally different because it propels it with the reaction force generated by ejecting high-pressure gas at high speed.”
He was definitely an engineer. I was familiar with the theory.
“Then do jet engines have intakes?”
“Of course not. It’s because it ejects high-pressure gas at high speed.”
“You still don’t understand me?”
Team leader Seo said that he was a genius after seeing Researcher Jung, but why is he so slow to understand?
“…? So you’re saying we’re going to put a jet engine on the car now?”
“No, ha…… Team leader Seo. Is this guy a genius?”
I couldn’t help but feel suspicious.
“hahahahaha… I don’t understand either.”
It was also disappointing for Team Leader Seo.
“So, it’s different from a gasoline engine and it’s different from a jet engine. The engine I’m trying to make will be a two-stroke engine without intake and exhaust.”
“…?”
“…?”
Their faces were full of curiosity.
“2-stroke gasoline engine ITE engine!”
Of course, energy is consumed in the process of intake and exhaust, which means that the heat has no choice but to go there, so the thermal efficiency is the same as the saying.
So what I came up with was to get rid of intake and exhaust and make an engine with a two-stroke engine.
“Does that make sense? How can compression and explosion occur when there is no intake and no exhaust?”
Team leader Seo expressed his doubts and said.
“We have to make that possible. We have to do that much to increase thermal efficiency.”
“……. How on earth? Isn’t it physically impossible?”
Certainly, with current technology, compression and explosion cannot be achieved in a stroke without intake and exhaust.
More precisely, it was a story that you couldn’t cause compression and explosion in succession.
“So I’m trying to come up with a new solution.”
“A new solution?”
“Yes. An electronic system to replace intake and exhaust will be included.”
“Huh? An electronic system that replaces intake and exhaust?”
“Yes. That’s not all. You know how electricity is created, right?”
“Yes. Turn the turbine.”
“Yes. Electricity is generated through electromagnetic induction. Current hybrids do electromagnetic induction with the power energy from the tires and wheels, right?”
“Yes. That’s right.”
“But what we’re making will be produced directly with electricity using the engine’s power.”
“No, wait a minute, did we hear that wrong? Then in the engine? Or in the crankshaft do you mean electromagnetic induction, a generator?”
“Yes. That’s right. This time you understand quickly.”
“No…… is that possible? It won’t be able to withstand the engine temperature, and that’s it, and to do that…… the axis of power is not one side. Ah!”
“Yes. Do you know what I need?”
“Yes! TT gear.”
“you’re right.”
They were silent for a while.
“I don’t know how the electronic system will go in yet, and I don’t know how the small generator that will be mounted on the engine will go in, but I think it’s possible. What do you think, Team Leader Seo?”
Researcher Jung said.
“It’s a hybrid engine.”
“A hybrid engine?”
“Uh, if that engine is made, it will be a hybrid engine. Not a hybrid that only has tire wheels like now… It will be an engine that gets power and electricity from the engine itself at the same time. A complete hybrid. In addition, the engine has mechanical devices. No, electronic devices go in. That part is also a hybrid.”
“Yes. That’s right. In a way, it’s a complete hybrid form. Power and power are obtained from the engine at the same time, and power is also obtained from the existing wheels. There is no intake and exhaust, so you can save more energy. Would you like to go up or not?”
Raising thermal efficiency was ultimately about saving energy.
“…”
“…”
“Now, let’s start slowly. First, I designed the skeleton of the engine. Let’s build it. Now, here.”
He said while giving Researcher Jung the blueprints that will become the skeleton of the engine.
“Please make this.”

A month had passed since the ITE engine was developed in earnest.
The ITE engine was outlined to some extent, and electronic parts related to intake and exhaust were also made. The name is AA, an abbreviation for administrative agency.
That wasn’t all. Even a generator that gets power directly from the crankshaft of the ITE engine using the TT gear was created.
Now all I had to do was assemble them and complete the engine.
“Well, first we now have to combine this electronic part with the engine.”
“Ah… I can see it. How does it intake and exhaust?”
“Yes?”
“And wow, the generator was made so easily through the TT gear. Certainly, it was great that the size restrictions were removed thanks to the TT gear. But what I’m worried about is whether it will withstand the heat of the engine. I think it’ll work according to the calculations.”
Team leader Seo said with a worried look.”
“I think it will work in theory…. I don’t know what will happen. Let’s finish it today. I’ll assemble the AA system with the engine right away. Team leader Seo and Researcher Jeong assemble a small generator.”
“all right.”
“yes.”
So far everything went smoothly.
I started to connect the AA system to the engine, and Team Leader Seo and Researcher Jeong started to connect the small generator and the crankshaft.
The screws were tightened and oiled and joined together.
Would it have taken an hour? In no time, the engine and AA system were all combined.
“I’m done.”
“Wait a minute for us too. We only need to tighten one last bolt.”
and after a while
“It’s done.”
“Now… I guess I can combine these two again.”
finally the last one An ITE engine is completed by simply combining the crankshaft and the engine.
“Let’s get started right away.”
We immediately started assembling the two parts into one, and it wasn’t long before we were done.
“……. Finally completed. ITE engine.”
Team leader Seo said proudly.
“Huh… Now if this works properly…”
Researcher Jung said as if he was worried.
While making the ITE engine, it was a little different from what I initially calculated. Depending on the weight of the vehicle, the fuel efficiency will change, but on average, the fuel economy was expected to be about 28km/ℓ.
1 liter per 28 kilometers. That alone was great.
“Let’s proceed to the test right away. Connect the fuel valve and inject oil. And the battery.”
Although the ITE engine was completed, there was still a little work left to make it work.
For the test, the team leader, I, and researcher Jung continued to move without a break.
The fuel valve was connected, the oil valve was connected, and batteries were attached to various test devices.
The steering hasn’t been put on yet.
If the engine works normally, I thought to test it by attaching the actual steering system after that.
“Whew… it’s over.”
I looked at the engine that was completed until the test run.
‘It’s definitely a very different look from the existing engine.’
If the existing engine was a pure mechanical device, now I made
The ITE engine had a lot of electronics as well as mechanics.
There were also many sensors for efficient heat treatment.
“Let’s get started.”
When I said this, Team Leader Seo and Researcher Jeong swallowed their saliva.
“Is it okay to flip this switch here?”
“Yes, that’s right.”
“Then I’ll switch up.”
“yes.”
Researcher Jeong raised the engine switch.
woo woo woo-
Then, a very quiet engine sound came from the ITE engine. It feels quite different from the sound of the previous gasoline engine.
If the sound of a gasoline engine is compared to a majestic waterfall, the ITE was a sound that reminded me of a quiet forest.
“Wow…it started.”
