Cao Jun didn't speak immediately, in fact, as soon as he said what he said just now, Cao Jun knew that he was in trouble: Mr. Lin repeatedly told him that he must not leak out about the engine, but he was about to tell the matter at this time...... At this time, Xiao Cao's heart was worried, and he peeked at Lin Hongfei from time to time.

However, Lin Hongfei did not blame Cao Jun at all, on the contrary, for Lin Hongfei, Cao Jun's revelation is at the right time, the matter of the star-shaped engine, if you say it by yourself, it is inevitable that there will be some self-suspicion of the princess selling melons, although the application range of the star-shaped engine is far less than that of the V-shaped engine, in the eyes of many people, the cylinder layout of the star-shaped engine has declined, but in the eyes of real industry insiders, in fact, the star-shaped engine has been developing over the years, Even with the impact of turboprop engines, the unique engine form of the star engine was not greatly affected.

Cao Jun, who was originally apprehensive, didn't see Mr. Lin angry, on the contrary, after seeing Mr. Lin nodding to himself imperceptibly, Cao Jun, who was still worried about how he should answer this question, suddenly breathed a sigh of relief, and hurriedly replied with a vindictive spirit, "It's in the workshop next door!" ”

"So what are you waiting for? Check it out! Hearing Cao Jun say that the star-shaped nine-cylinder engine was so close at hand, Feng Lao and Xu Lao immediately couldn't wait to say.

"Yes, go over and have a look!" Several other old experts were also very curious in their hearts, and shouted along.

These days. It is enough for several old experts to understand the history of the Beijun Industrial Manufacturing Company clearly, after knowing that even half a year ago, the Beijun Industrial Manufacturing Company was only a half-dead municipal state-owned enterprise that could survive by relying on the allocation of the municipal finance, several old experts were shocked, and they felt more and more that they could not see through Lin Hongfei, a young man: not only the leading engine design expert in China. At the same time, he is also a nimble businessman, and most importantly, he is only in his early twenties...... How did this kid do it? Is he a wicked?

But all of this is not as shocking as the news that Cao Jun shook out, the star engine, in the turbine engine...... This turbine engine refers to various types of turbo engines, including turbojet engines, turbofan engines, turboprop engines, and turboshaft engines...... Not before it came out. This kind of engine dedicated to the aviation flag represents the crown of the world's engine manufacturing industry, and even now, the country cannot come up with several star engines with high technical content, otherwise the country would not be in contact with Poland now. It is hoped that a 1,000 hp radial engine will be introduced from Poland.

If Lin Hongfei can really come up with a star-shaped nine-cylinder engine that can be used, what does this mean, how can several old experts not understand? This means that the Republic will no longer have to be controlled by others in the field of engines from now on! The most important thing is that Lin Hongfei is still so young!

It is precisely because of this understanding that these old experts are so eager for this radial engine.

"It made the teachers laugh. In fact, I'm just doing things indiscriminately," Lin Hongfei smiled very shyly, and consciously positioned himself in the position of a young junior who was supported by respected elders, "Please move, teachers." If there is anything inappropriate, please ask the teachers for advice. ”

But I didn't expect these old experts to "appreciate" at all. The elder waved his hand even more humorously, "Xiaolin." That's not right, we old guys have been building engines all our lives and haven't made a decent engine, you're embarrassing our faces, don't you dare to point out. ”…,

Hearing Zhang Lao's witty words, the other old experts suddenly laughed, although the old Zhang Tou's words were a little ugly, but it is really this reason, if you say that the qualifications and weight of the old man in western Zhejiang in the domestic engine industry, he will naturally throw Lin Hongfei out of the kid and go to eight streets, but if you talk about the real ability, these old guys are far worse than Lin Hongfei.

This is not easy to accept, Lin Hongfei can only scratch his head and smirk.

………………………………………………………………

Several old experts are not a turtle who has not seen the world, when they see the huge star-shaped nine-cylinder engine in front of them, they still can't help but sigh in admiration, and their eyes are even more scorching: although I don't know what the actual performance of this engine is, but any kind of industrial product, if the performance is good, the shape must have the beauty of modern industry, simple and smooth, looking at people feel pleasing to the eye, and the same is true of the engine in front of you.

The heat sink on the upper surface of the cylinder is evenly distributed, with the professional vision of extremely old experts, it can be seen at a glance that the heat sink arrangement on the cylinder not only has good heat dissipation performance, but also has a certain diversion effect, which can guide the cold air to the back of the windward side of the cylinder as much as possible, so that the entire cylinder can get uniform heat dissipation, so that such a large cylinder can be evenly dissipated, which itself is the most test of the engine designer's design skills.

This alone made the eyes of several old experts change when they looked at Lin Hongfei, "Good guy! With such a large cylinder, the displacement of each cylinder must be more than two liters, right? ”

"Well, each cylinder is 2.7 litres of displacement, and the total displacement of the entire engine is 24.3 litres."

"With such a large exhaust volume per cylinder, Kobayashi, how did you manage to make the mixed oil and gas in it fully combusted?" When Xu Lao heard this, he immediately asked a sharp question...... This is also the most troublesome problem for them, the cylinder is bigger, the exhaust volume increases, this is not much difficulty, but how to ensure that the oil and gas mixture into the cylinder can be fully and effectively combusted, which is a great test of the designer, the domestic Yun 5 transport aircraft engine has always been a big problem, the most important point is because the mixed oil and gas in the cylinder can not be fully combusted, the fuel in the cylinder can not be fully done.

didn't wait for Lin Hongfei to answer. Having been staring at this engine blankly, Feng Lao suddenly became excited, and suddenly turned his head to look at Lin Hongfei, with uncertainty in his eyes. "Five spark plug ignition per cylinder?"

Wow~~!

Several old experts who didn't notice this point were stunned at first when they heard Feng Lao's words, and then immediately showed agility that was completely different from their age, and almost in the blink of an eye, they gathered around the engine, looking at the cylinder of the engine, and after seeing it clearly, everyone was sighing and praised: Sure enough. Each cylinder is equipped with five spark plugs, and looking at this momentum, it is clear that the ignition method of five spark plugs per cylinder is adopted.

Increasing the number of spark plugs is an excellent way to improve fuel efficiency. At the same time, it is also the easiest way, and it is very ashamed to say that the domestic engine really does not take this into account: the fuel combustion in the cylinder is not enough? Wouldn't we be able to solve the problem by increasing the number of spark plugs?

"This is one of the solutions, in addition to increasing the number of spark plugs, we also use vortex technology." Lin Hongfei said, picked up a piece of paper and a pen from the workbench next to him, and said while drawing, "Enter the oil-gas mixture in the cylinder." Instead of going in in a straight way, it ...... in a vortex way"...,

The old experts are well-informed people. It was only through Lin Hongfei's hand-drawn sketch that he immediately realized the benefits of using vortex: not only can it ensure that the fuel and gas are mixed more evenly. At the same time, it can ensure that the oil-gas mixture can be distributed more evenly in the cylinder...... The use of this vortex method, which can be mixed more fully, supplemented by five spark plugs per cylinder for strong ignition, can indeed ensure that every cent of energy in the fuel can be fully utilized, but the effect is much more efficient than the ignition method of the previous engine.

Although I am very curious about how Lin Hongfei managed to enter the oil and gas mixture in the cylinder in this vortex state, several old experts know better in their hearts that Xiao Lin can tell everyone the principle, this favor has reached the extreme, if he opens his mouth to Xiao Lin again, several old experts themselves feel that their faces are not happy.

"Kobayashi, how is the actual performance of this engine? How much power is the maximum? Old Xu calmed down and asked Lin Hongfei.

"1200 horsepower, if the finishing capacity can be a little better, it is easy to break 1500 horsepower."

"Good guys!" Several old experts gasped at the same time: Isn't this more powerful than the SAZ-62IR radial nine-cylinder engine that we hope to introduce from Poland? Poland's SAZ-62IR engine is only 1000 horsepower, 200 horsepower lower than Kobayashi's, the most important point, Kobayashi just said, that is, our domestic processing capacity is not good, if the processing capacity can go to a higher level, this engine can easily break through the 1500 horsepower mark!

Since ancient times, heroes have come out of youth!

"It seems that for Xiao Lin, the V8 engine is really not difficult," Feng Lao looked at Lin Hongfei, with only emotion and hope left in his eyes, "How about it?" Comrade Kobayashi, come and help us? ”

"This matter is not something that the two of us can decide, right?" Lin Hongfei frowned, he was actually thinking about this question from the beginning just now, "This engine is prepared for the military parade in the year after tomorrow, and many things in it are not decided by the General Headquarters of the Month, can your factory make this decision, Feng Lao?" Also, after this engine is made, whose patent is it? ”

Lin Hongfei's words made Feng Lao a little embarrassed.

Yes, I was so excited just now that I forgot even the most important thing, yes, Comrade Kobayashi's ability in engine design has been seen with his own eyes, and he will never doubt whether he can figure it out, but this matter is really not up to him, providing a high-performance engine for the National Day parade parade is just a very serious political task, but it is not what the old man himself wants to say, it is up to the parade headquarters to decide, If the parade headquarters thinks that Lin Hongfei's qualifications are not enough, or his political quality is not up to par...... And so on and so forth, there are all kinds of things, even if one of them is unqualified, then no matter how great Comrade Xiaolin's ability is, this task must not fall on Lin Hongfei's head.

And the most important question is, as Lin Hongfei said, if this engine is made, who will the patented technology be?

There is no doubt that in terms of the level and skill shown by Comrade Kobayashi, if Comrade Kobayashi can participate in this project, he will be the backbone, and it is not too much to say that he is the inventor of the patent, but according to the tradition of our country, the patent of this engine can never belong to Lin Hongfei.

After a few days of getting along, Feng Lao can also see that Xiao Lin can never be like these old men like himself, only talk about dedication and not return, this kid is such a No. 1 guy who "let me dedicate, but also give me something back", people have worked hard to complete such a big task, and in the end, except for a little bonus and a few praises, there is no actual benefit...... It is estimated that this kid will not agree. …,

As soon as he thought of this, Feng Lao's heart couldn't help but feel a little bitter, such a good opportunity, such a great young man...... But what has become like this?

Several other veteran experts also realized the problem, and their brows immediately furrowed.

Only Feng Lao still didn't give up, and his face was a little gloomy for a while: if he went back, put on his old face and listen to the leaders of the parade headquarters to explain well, maybe this matter could be done?

"Xiao Lin, if, I mean if," Feng Lao asked cautiously, "What do you mean if the leader above agrees to let you get involved?" ”

"The leader promised me to do this?" Lin Hongfei's expression was suddenly surprised, I don't know what Lu Dao is for, hearing Feng Lao's words, Lin Hongfei's heart just has a feeling of wanting to laugh, "Feng Lao, it's not me pouring cold water, this is simply impossible." ”

But Xu Lao was very reluctant, he didn't listen to Lin Hongfei's account at all, and said stubbornly, "It may be impossible, this is my business, Xiaolin, you just tell me a word, if the parade headquarters agrees, you can't come over?" ”

Feng Lao said this again and again, and Lin Hongfei couldn't help but think about it seriously: Feng Lao really planned to come like this?

After thinking carefully for a moment, Lin Hongfei gave the answer, "If this work is clearly based on me, and the patent after success belongs to me, or at least 70% belongs to me, there is no problem."
