Rising: Ten Thousand Years Chapter 387: : Unqualified

Before everyone thought that diesel engines were not easy to study because they were not familiar with the characteristics of diesel engines.

It is only generally known that diesel has a lower self-ignition point than gasoline, but it is not easy to ignite with an electric spark. And poor mobility.

But I didn't expect diesel to be compression ignited in this way.

It is difficult to say, but it is also easy to say.

In terms of technology, diesel engines are far inferior to gasoline engines with electronic ignition.

With crude technology, the cost of diesel engines will drop significantly.

The people in the Motor Academy suddenly felt that they were sure.

On the same day, the Mobile Academy was divided into two parts.

Part of the research and development of drawings and structures of agricultural machinery.

The other part, led by Ma Jianbin, began to develop the compression ignition test diesel engine.

The matter of the Kyushu Academy of Sciences has been settled. Li Zhen was very relieved to hand it over to the Motor Academy to do this.

The Motor Institute is a group of people who have researched several generations of engines, have mature technology, and experienced research and development. Some people have even figured out the rotary engine, and the diesel engine is just a child's play for them.

Tell the truth.

Even without Li Zhen's suggestions and lectures.

Ma Jianbin and the others do their own research. As long as they thoroughly study the characteristics of diesel oil, they can figure it out in two days. Developing diesel engines is not as difficult as they imagined.

Li Zhen let go of this matter.

After staying at Kyushu Academy of Sciences for a week, good news came from Ma Jianbin. It is said that the first diesel engine has been made.

The efficiency is really fast.

It took two days for everyone to design the drawings, but it only took five days to make them.

This efficiency is extremely fast. The main reason is that they have too much experience in engine research and development. The diesel engine is only different from the gasoline engine in the ignition method, and the powertrain is actually similar to the gasoline engine.

Li Zhen was invited to visit the Motor Academy;

Many people are quite curious, some can't imagine, why can the ignition be completed by manpower?

I feel that this is very complicated.

It's not complicated at all. It's just that they don't understand the characteristics of diesel. As soon as you talk about it, that's what happened.

The first diesel engine was much bigger than expected.

Square head and square brain.

It is about half a meter long and about forty centimeters wide.

Compared to a gasoline engine, this size is quite large. Neither the gasoline engine nor the battery has such a volume.

Mainly because the compression ignition system they designed is more complicated. There is no way to do this. It is only the first generation of diesel engines, and the compression ignition system cannot be simplified.

This square-headed guy has an oil pot hanging above it, and the oil pot is filled with diesel oil, which will leak into the combustion system below by dripping.

On the side, there is a hole thicker than a thumb, and there are several buckles in it. This hole is the ignition system of the diesel engine.

After Ma Jianbin introduced the function and principle of the diesel engine to everyone, he tried to poke a Z-shaped steel rod into the hole.

Everyone couldn't help frowning, did they really rely on human power to ignite the fire?

What is the reason for this?

Although Ma Jianbin explained, most people did not understand. In the clouds and fog, I still feel in my heart how this can be ignited by shaking it?

Is it heating through friction? Isn't this too hasty?

Ma Jianbin didn't give too much explanation, and with all his strength, he took a deep breath and suddenly started to shake the joystick.

"Hi!"

A low drink.

The joystick does not move at all.

Ma Jianbin couldn't help but froze, and after a while, his face turned red.

Ten seconds later, I was discouraged.

Everyone was dumbfounded.

Is it so difficult?

It doesn't work at all.

Ma Jianbin waved his hand: "Here is a strong one."

A muscular young man walked out of the mobile yard, spit on the palm of his hand, took a deep breath, grabbed the joystick and began to shake it vigorously.

Holding his breath, he tried hard to push the rocker around.

'Boom'

There was a muffled sound from the diesel engine.

After one lap, with the support of inertia, the rocker became much easier.

The young man began to shake violently again. Extremely fast.

The diesel engine began to make a muffled noise continuously.

'Boom boom boom;'

Then a cloud of black smoke rose from the vent.

Everyone's eyes widened, is it really smoking? Is it really possible to burn it by manpower?

The speed of the rocker is getting faster and faster, the black smoke from the diesel engine is getting bigger and bigger, and the sound is getting louder.

'Boom boom boom'

At this time, the diesel engine made a sound of starting. There seems to be a lot of power inside, and there is a constant bang, with a little 'bang bang' sound. And with the sound, it jumped and jumped.

The young man took a few breaths tiredly, took off the joystick and stepped aside.

An operator stepped forward and pushed a push rod on the diesel engine to control the throttle.

The 'hum hum' diesel engine suddenly roared.

Then the rotor connected to the diesel engine began to rotate. Great power.

No, it should be said that it has a lot of torque.

Everyone was dumbfounded.

Is this all right?

Why is this?

Liu Jinghong was also someone who had studied steam engines before, so he was dumbfounded when he saw this scene~IndoMTL.com~What is the reason for this? "

"It's unscientific. Why can it be compressed and ignited by manpower?"

"Is there something like flint and steel in it?"

Ma Jianbin explained: "No. It is because the air is compressed, and the air in the cylinder is compressed to a critical point. Under high pressure, diesel fuel spontaneously ignites."

"Is this okay too?"

"Compressed air can set it on fire?"

"This is so unscientific."

"Regardless of the principle of it, you are not practical at all."

"Why is it not practical?"

"It's really not practical. Although it doesn't need to be electronically lit, it's too laborious, right? Who can ignite it like an ordinary person?"

Ma Jianbin stuck his neck and said, "Who says it can't be done? Let's design the joystick to be easier to push and use the principle of leverage, which will make it much easier. It's just that the joystick is not well designed."

Li Zhen also frowned and said, "You can't do this."

Ma Jianbin lowered his head nah, without explaining. Li Zhen said no, he dared not speak.

Li Zhen shook his head: "This compression ignition system is not well designed. You have to redesign a more labor-saving one inside. Even if you change the joystick, ordinary people can't use it. It does take some strength to push the diesel engine, but this The strength should not be too great. Otherwise, ordinary people will not be able to start it, so they can only watch, and it will take a lot of time. You can’t have to find a young man every time you start it?”

Ma Jianbin frowns: "But, it is the structure. The air needs to be compressed inside, which is atmospheric pressure. We have passed the mechanical principle and have reduced this to the minimum."

Li Zhen took a look at the blueprint, hesitated for a moment and said, "It still needs to be changed."

"You can't do this."

"Then how to change it?"
