Seeing that few people were looking at him, Meng Wentian raised his voice and said, "What should I do?" I have a good way, that is-" Speaking of this, he deliberately paused, and when everyone looked at him sarcastically, he said loudly, "Layered!"

Expert Wang blurted out and asked, "What do you mean?"

Other experts also began to focus on Meng Wentian.

Meng Wentian smiled: "This is the third method that I came up with, layering." What does that mean? I've managed to get two different layers of gasoline mist in the cylinder. The concentration of gasoline close to the igniter is high, while the concentration of gasoline away from the igniter is low......"

Expert Wang was stunned for a moment and asked again, "What's the benefit...... Wait a minute......"

At this time, Professor Zhao said in surprise: "Yes, yes, this method is good. Xiao Meng, no, Boss Meng, you tell us about the benefits of this method. ”

The other experts were stunned for a moment, first looked at Professor Zhao in surprise, and then looked at Meng Wentian, with a thoughtful look in their eyes: they began to really think about Meng Wentian's thoughts.

Meng Wentian smiled and asked, "What would happen if we could create two different degrees of gasoline in the cylinder and let the mist with a high concentration of gasoline approach the igniter?"

Expert Wang replied like a student: "It will happen, and the mist with a high concentration of gasoline around the igniter will easily burn, wow——, great! Your idea is too scientific!"

Then, he said excitedly: "This high-concentration oil mist will generate a lot of heat when it burns, and it can instantly increase the temperature in the cylinder, and the surrounding low-concentration oil mist can also burn." It's wonderful! It's a good method! It's a stroke of genius. ”

"yes, isn't it?" the experts nodded in surprise.

The people here are all experts and professors, and they are even smarter, with Meng Wentian piercing this layer of paper, how can they not understand the truth?

Seeing that everyone understood their thoughts, and their eyes looking at them were very different from before, Meng Wentian smiled in his heart: Hehe, you are shocked, right? This is the most basic direct injection technology layered combustion theory on the earth, using the oil mist mass with high gasoline concentration to ignite the fully atomized oil mist, which perfectly solves the contradiction between the full atomization of gasoline and the difficulty of ignition.

At this time, Expert Wang asked very modestly: "Boss Meng, how do we achieve different concentrations of atomized oil mist in the cylinder?"

Meng Wentian said in a surprising voice: "There are two ways. ”

"Ahh

"Cut! We experts have only recognized your idea of different concentrations of oil mist, and we have not yet fully demonstrated whether your method is really scientific, let alone verified by experiments, but you kid said that you have come up with two methods? Who believes it? ”

"Foreign countries haven't reached this point yet, and you kid is not ashamed. ”

"Boy, you're smart enough to come up with different concentrations of oil mist, what else do you want to show off?"

"If you have two methods, then we experts should hide our faces and sneak back, and only dare to hold our wives and children at home. ”

"You really think you're a genius who hasn't been born for a hundred years. ”

"Unless you're the best scientist ahead of your peers in the world, hehe......"

"Blow it, let him blow it, he's the boss anyway. ”

……

Meng Wentian ignored their comments and ridicule, but picked up an oil paint pen and drew it on the display board.

Looking at the mechanical cross-sectional view he drew, several experts showed surprise again, one by one, you look at me, I look at you: Isn't this kid a high school student? How can he draw mechanical schematic diagrams and cross-sectional views? And still draw so standardly?

The experts who were talking about it just now all closed their mouths, looked at the picture drawn by Meng Wentian seriously, and thought silently, thinking in their hearts: Could it be that this kid really came up with a way? Impossible.

After all, it was just the original picture, and Meng Wentian drew it very simply, and it was finished in a few minutes.

He coughed deliberately, pretending to clear his throat, and when everyone looked at him, he said, "This is the first solution I came up with." The easiest way to do this is to change the shape of the piston head in the cylinder block. …… Now I've changed the middle part of the piston to a rounded protrusion. What does this do? I put the fuel injector here, when the gasoline comes out of the injector, most of the gasoline will be injected into the various spaces of the cylinder, and it will be fully mixed with the surrounding air, which is the same concept as we thought of atomization before, these air masses containing gasoline have less oil content and are not easy to ignite. The other part of the gasoline will be sprayed into the arc-shaped protrusion that I daught, and because this gasoline is emitted at high speed, according to the principle of hydrodynamics, it will flow rapidly along the top of the arc-shaped piston, forming a cyclone in this area. ”

The principle that Meng Wentian said was very simple, and all the experts nodded in agreement.

Meng Wentian continued: "This cyclone squeezes out some of the air as it rotates, and the concentration of gasoline here is naturally relatively high. As we all know, during piston compression, the piston moves upward, and it naturally pushes the oil mist at the top to move upward. As soon as the piston moves near the igniter, the igniter starts to ignite, and this high concentration of oil mist will be ignited and burned, which will inevitably emit heat to the surroundings, thus igniting all the gasoline in the cylinder......"

"Wonderful! Wonderful!" the surprised expert Wang slapped the table and said loudly, "It's great that simply changing the shape of the top of the piston can solve this contradiction." ”

Not to mention that those senior experts understood, they all thought that Meng Wentian's solution was simple and practical, and they couldn't help but nod their heads in surprise, even Yan Weizheng, a graduate student, also understood. He asked excitedly, "Boss Meng, what about your second solution?"

Meng Wentian smiled: "The second method is simpler......

"Ah-" one expert blurted out, "can't it?

Everyone looked at Meng Wentian in disbelief, but this time no one ridiculed him anymore, and they all waited excitedly to say the second way.

Meng Wentian said with a smile: "The second way is to let the fuel injector carry out the second or even third injection. ”

"Oh-" everyone exclaimed as if they suddenly realized, isn't it? Spray a stream of gasoline near the igniter a moment before ignition, and the gasoline has not had time to atomize, its concentration is naturally high, and it is naturally easy to ignite.

Expert Wang raised his hand again to slap the table, but in the end he held back and said: "This method is easy to say, but the requirements for chips are strict, and it is not easy for our research institute to achieve." ”

Although this best method is difficult to achieve because of the chip, it does not prevent everyone from admiring Meng Wentian. If it weren't for Meng Wentian's age being too young, those experts would have wanted to worship him as a teacher.

Meng Wentian's method is not very profound, but it can solve the problem: the solution that can solve the problem is a good way, the simpler the better, and the more clever it is.

They don't know, it is precisely because these methods are simple that Meng Wentian is easy to understand and remember most clearly when he was a repairman in his life. If it were really profound theories and principles, he might not be able to say them today, at least not as confidently as he is now, and dare to talk eloquently in front of all experts.

Just like Professor Zhao's concern about the control chip, Meng Wentian can't say anything, at most he just talks about the functions that the chip should have, and he doesn't know anything about how the chip is designed, the circuit logic inside, or whatever.

The basic principle of direct cylinder injection is clearly explained, and the rest is how the experts achieved it. Meng Wentian couldn't make any good suggestions on how to achieve it, and he didn't want to brag about the specific design and manufacturing methods of the cylinder block. He only asked them to immediately deepen the two methods they had said, and form written materials as soon as possible to apply for technology patents at home and abroad.

When Meng Wentian said goodbye to the experts, Guo Qiulan went home after talking with the cooperative manufacturer about the production of the reversing anti-collision radar from other places.

Seeing Meng Wentian, Guo Qiulan's tired expression changed, and she asked with a smile, "Are you here?"

Meng Wentian smiled: "I came here a long time ago." I just talked to an expert for a while about direct injection technology for gasoline engines. …… You're done? ”

Guo Qiulan said with a smile: "Talk to the experts about direct injection technology? You are watching them talk, you pour water and serve tea for them, right?"

The two laughed and walked into the house where she lived. As soon as she came in, she seemed to have lost all her strength, and her body fell into Meng Wentian's arms softly, muttering: "I can't think of so many things, I can't be lazy if I want to." ”

Meng Wentian hugged her gently and said, "Lan'er, you can hire a few more people to help, there is no need to run around." ”

Guo Qiulan took the opportunity to put an arm on Meng Wentian's shoulder and said, "I haven't figured out what to do yet, how dare I hire someone else to replace me right away? Once I'm familiar with the process and have accumulated more management knowledge, it's almost as good as hiring someone else. ”

Meng Wentian bent down, reached to her knee with one hand and supported her back with the other, picked her up horizontally, slowly walked to the sofa in the living room, and said, "Anyway, you have to take it easy, now that someone else has asked us, you are still so tired." In case in the future, we beg others to buy our products and need us to look around for the market, you are not more tired?...... Money is endless, and we don't need to work so hard. ”

Being hugged by Princess Meng Wentian, Guo Qiulan felt very warm, smiled sweetly, and said: "I have to work hard, otherwise I will be compared to other women, and I don't know if I will be able to see you in the future." Wen Tian, now you like Wang Ruxue so much, right? She helped you so much this time. ”

Meng Wentian smiled bitterly and said, "What do you have in your heads?...... I...... Am I really worth all your efforts?"
