Bai Hao was thinking about how to explain the source of this prototype drawing.

Who would have thought that Wang Meilin told Bai Hao directly the answer: "The independent research and development of the 9th Factory has been influenced by some foreign technologies, but we firmly follow the path of independent research and development. It takes time... Then look at what we release the full version of that big guy, and you will say how long it will take."

Bai Hao reacted and immediately said, "Deputy Secretary, you are wise."

How did you find this thing?

No need to tell anyone.

No one is qualified to ask how Bai Hao designed this thing.

People who are qualified to ask in Xia Country asked, and they want to answer in one sentence:

This is a diesel engine independently developed by Factory No. 9.

People outside the Xia Kingdom asked.

Yes, keep it confidential!

Wang Meilin's words not only told Bai Hao how to answer the question, but also told Bai Hao that whoever wants to ask too much is to block Bai Hao.

Because Wang Meilin had a vague feeling.

A feeling that I roughly understand but cannot express it.

At this time, Wang Meilin's tone became serious: "Tell me a solid foundation. How long will it take for the machine to be practical? "

Bai Hao thought about it and replied: "If it is really used for farming, it can be done today... The other uses will take at least one and a half years to optimize and improve the details. Among them, there are dozens of sub-items, and our No. 9 Factory held a meeting and discussed in depth."

"Tell me, I probably understand." Wang Meilin is also an old college student and has been in the Fifth Works Department for many years. He is confident that he knows some basic knowledge.

Bai Hao drew a simple structural diagram on the ground: "The core technology of the diesel engine is to put it bluntly, which is four words: air intake, compression, explosion, and exhaust. We have considered using electronic control, so there is a need for electronic control, high voltage, common rail, and many sensors, which does not include the accuracy of the machine itself."

"Also, why can this machine reach more than 1,500 horsepower? It is not necessarily the same size that others can make. One of the core technologies is high pressure. We have removed five pairs of wheels, and the injection pressure is up to 50 pa, while ours can reach up to 200 pa."

Wang Meilin nodded. It sounded simple, but in fact it was so difficult that no factory in Xia Country could do it.

If the pressure is high, the atomization is good, the combustion will be sufficient, the power will be sufficient and fuel-efficient.

Bai Hao continued: "The common rail, fuel injectors are not one, but it is impossible for each fuel injector to be equipped with one, so there must be accurate calculations. Therefore, we choose electrical control. Each fuel injector can spray oil of the same mass and pressure, and run smoothly and the power will be strong."

Wang Meilin gently pounded her head twice.

This seems to be one of the basic principles of diesel engines, but why hasn't anyone ever thought of it for so many years?

Some people may have thought of it, but why is there no unit working hard on this?

Bai Hao continued: "Deputy Chief Wang, that seems simple. Several pairs of coupling parts outside a nozzle are subject to pressure from a ton of upwards. They also need to move flexibly, and they cannot leak oil. The gap is only two wires. My father is also an eight-level fitter, but eight of the ten pieces he processed are not qualified."

Wang Meilin wanted to ask Bai Hao how difficult this is.

But he didn't ask until he said that, so he was going to concentrate his efforts to see if there was a way to break through these difficulties.

Besides, when the five pairs of wheels approached, Miao Fenglin had a very good idea and the theoretical test was fine. He made some minor changes to a set of fuel injectors by himself.

Jiong Shuisheng took a few steps back and lit a cigarette, looking up at the sky at an angle of 45 degrees.

He didn't go to see it, he listened.

Li Xuesheng also came over in the distance, glanced at him from a distance, left, and then hugged his arms to see from a distance.

After a few minutes, start.

Immediately afterwards, there was a burst of noise, the exhaust pipe was filled with black smoke, and the diesel engine began to shake, which scared everyone, so I quickly turned off the engine.

Miao Fenglin put on gloves and went to remove them immediately, regardless of how hot the machine was.

After taking it off, I saw that the fuel injector and the entire cylinder were burned inadequately, causing oil stains and charcoal marks. After only a few seconds of activation, it turned out to be like this.

Why is this happening?

Miao Fenglin suddenly turned around and looked at Jing Shuisheng who had retreated to the distance.

Someone said, "Did he wait on purpose..."

"Shut up!" Miao Fenglin roared: "Jing Shuisheng has a stinky mouth, but he is not a villain. If you can't figure it out, think about it carefully. If you don't understand, get out!"

Li Xuesheng smiled. He knew that Miao Fenglin had found the key point, but it was still a little short of it.

I turned around to the table, picked up the drawings and rolled them up, still hugged them with my arms, clamped the drawings at the bend of my arms, and stood in my position just now to look at them.

What is the reason, what is the reason!

Miao Fenglin got into the machine warehouse. He looked at the machine inch by inch, studying it one centimeter, one centimeter after another. When he saw the circuit board, he jumped out and his eyes swept over everyone behind him.

Here we gather the backbone of almost the top diesel engine research institute under the Ministry of Industry of Xia.

Finally, Miao Fenglin saw a person, reached out and grabbed him: "Hurry, see what this is?"

That was an electronic control expert. When I got in, I realized: "Control, the circuit and layout are used to control each cylinder. There should be more than one, and there are others."

Miao Fenglin stood on five pairs of wheels: "Lao Jiong, drawings."

Jiong Shuisheng pointed to Li Xuesheng, but saw Li Xuesheng standing there with the drawings in his arms.

When Miao Fenglin ran over, Li Xuesheng's two students came over with a table.

He is an expert.

After studying it carefully for five minutes, Miao Fenglin smashed it on the table with her head: "I'm just a pig, a stupid pig."

His method works.

But it destroyed the balance between all fuel injectors. In a word, if you want to change, you can change everything. You cannot change a cylinder. How could he not understand this simple truth? Just looking at Jiong Shuisheng, he removed a fuel injector, so he only changed one of the rear embolizations.

That is just a few small changes.

But it destroys the overall balance.

Manually, then an insider adjusts the control circuit on the microcontroller.

After half an hour of tossing, it finally started.

Jiong Shuisheng listened with his eyes closed.

When they reach their level, they can hear too many things by listening to the sound of the diesel engine running.

A minute later, Jiong Shuisheng shook his head.

At this time, Bai Hao and Wang Meilin also walked down, and Bai Hao asked, "What, I don't feel good."

"No, the operation is more stable, but the power is obviously reduced. I guess I lost at least twenty to thirty horsepower. I can't say he is wrong. After he makes this change, he doesn't pick up much oil. He adds a set of improved fuel filtration. I guess any oil can be made. I pursue the ultimate, the practicality he pursues. Now think about it, he may be right."
