"Yes, our meeting is to put forward various plans, and then everyone will discuss them with each other." Minister Zhu spoke: "Since a machine factory also has a plan, then, we can listen to it, discuss and discuss, Lao Niu, in a while, you will also give them advice." ”

Niu Shilong was petrified in an instant.

Want my opinion? What can I understand? Isn't this tearing down the stage for me? If he praises the other party for being good, then he can make up a few words, but if he says that the other party is not good, then he must say what is not good, this is not something that can be made up casually.

He felt his head grow for a while.

And Qin Zhenhua was satisfied.

"The last time we went to Europe, we gained a lot." Qin Zhenhua said: "The advanced technology and concepts of the West are worth learning from us, and after we came back, we have been conducting research for several months, and now, we finally have a formed plan." ”

After speaking, Qin Zhenhua beckoned to Wang Erzhu: "Erzhu, up." ”

So, the center of the conference room, the slide projector, was turned on, and Wang Erzhu walked over with a stack of slides.

In this era, there is no kind of projector connected by a computer, even in this kind of national-level meeting, the use of old-fashioned slide projectors with transparencies, and because many people are not familiar with this kind of thing, they do not value it, so they are not willing to use it at all, especially the masters, even more disliked.

Zhang Baolin just now didn't use it when he reported, but Qin Zhenhua is different, if you want to introduce it to you carefully, it is absolutely impossible not to use a projector.

Moreover, he had already prepared for the sake of their new diesel engine, and these slides were drawn by the best masters in the factory before setting off, which was definitely the most beautiful industrial drawing.

The slide projector warmed up for a minute, and then, the clear image hit the front projection screen, which was a complex-looking, but extremely delicate engine profile.

"In order to reduce the size of the engine, but also because we have been producing for many years and are more familiar, we still use the V-shaped 60-degree angle structure, and the design of the cylinder block is roughly the same as before, but we have increased the cylinder core distance, so that we can avoid a series of problems caused by the existing cylinder block, and have good power improvement potential."

In order to achieve a compromise, we plan that the speed of this engine cannot exceed 2,500 rpm, otherwise it is not easy to solve the heat dissipation problem after the speed increase, and in the end it will outweigh the losses, so it will be maintained at 2,400 rpm, or 2,450 rpm. ”

Qin Zhenhua has just put forward the design flaws of the coal provincial diesel engine factory, and his own design plan is just to perfectly solve the defects of the product.

"We plan that the initial power of this diesel engine will reach 735 kilowatts, that is, about 1,000 horsepower, and then further increase to 883 kilowatts, that is, 1,200 horsepower.

"Hmph, it's easy to say, how much can you achieve with this slide? Your satellite is not small. When he saw this, Niu Shilong finally couldn't help but speak, you touch the skin of your mouth up and down, it's easy to say, but it's hard to do!

Although Niu Shilong does not know anything about technology, but how much effort has been made by the Coal Provincial Diesel Engine Factory to complete the research of the 537 kilowatt engine, he only knows how difficult it is, and he absolutely does not believe that he can develop this kind of engine at the level of the diesel engine factory of the first engine factory.

After speaking, Niu Shilong pointed to the sign in the upper right corner below and said, "What's the matter with your name?" ”

He's a layman, of course, from a layman's point of view, this slide is drawn with meticulous lines, so the details are in place, especially in the upper right corner, there is a line of text.

Introduction of 150HB diesel engine.

The letters behind it, Niu Shilong can't be called, people in this era don't learn pinyin, so they don't know the name of pinyin, they don't learn English, they don't know the name of English, in short, it has to have a name, right?

Just like their project, it is X150, this X, which means unknown, means that they have an unknown height, and what does this HB mean?

It's not like you're going to make all this fancy.

Qin Zhenhua was also speechless, he couldn't grasp the main problem, he could only grasp these unimportant side details, he was really a layman.

"We gave it a loud nickname, the Panther." Qin Zhenhua said: "We hope that after installing this diesel engine, our tank will be as fast as a panther." ”

Qin Zhenhua said casually.

(What does this HB mean, Huadong Zhixiong doesn't know, some say that it is H-shaped steel, B is a thin-walled type, but it always feels like it has nothing to do with this engine, and it may also be a secret.) In short, in our book, this HB should be explained as a Black Panther, the Black Panther diesel engine, which sounds very domineering, and the readers who are about the same age as East China Zhixiong are big, and they should have liked the Black Panther Band. ）

"Even so, it won't be easy to reach 883 kilowatts." Zhang Baolin didn't care about Niu Shilong's question, he wanted to talk about the most important technical issues.

This is not what you say is what, the technical data is not up and down the mouth can come out, even if your design ensures the strength, what about the combustion efficiency of the engine? The engine can't do that much work, and everything is in vain.

The 1200 horsepower engine is not so easy to get, look at the British, it took a lot of effort to get it, and it was regarded as the most advanced thing, and it was originally said that it was sent to its own side, but as a result, people found an excuse and sank to the bottom of the sea.

With your current ability, can you do it? You know, the foundation of this engine, after all, is only 500 horsepower!

"That's a good question." Qin Zhenhua said: "Next, let's look at the second slide. ”

The second pillar has been on the side of the slide, and now, the overall picture is presented, and of course it is the turn of the step-by-step introduction to the picture.

The second one is typed, and there are very few parts, and what is drawn on it is a small part of it, the turbocharger.

"First of all, there is the turbocharger, which directly determines the crushing capacity of the engine."
