"Yes, the purpose of our meeting is to put forward various plans and then discuss them with each other." Minister Zhu said: "Since the No. 1 Machinery Factory also has plans, we can listen to them and discuss them, Lao Niu
Ah, in a moment, you can also give them some advice."
Niu Shilong was instantly petrified.
You want me to give advice? What do I understand? Isn’t this trying to undermine me? If you praise the other party well, then he can make up a few random sentences, but if you want to say something bad about the other party, then you have to say what’s wrong with it.
Yes, this is not something you can just make up.
He felt dizzy for a while.
Qin Zhenhua, on the other hand, was satisfied.
"We gained a lot from our last trip to Europe." Qin Zhenhua said: "The advanced Western technology and concepts are worth learning. After we came back, we have been conducting research for several months. Now, we finally have
The plan has been finalized.”
After speaking, Qin Zhenhua waved to Wang Erzhu: "Second pillar, come up."
So, the slide projector was turned on in the center of the conference room, and Wang Erzhu walked over with a stack of slides.
In this era, there was no projector that could be connected to a computer. Even at such a national-level meeting, the old-fashioned slide projector with transparent film was used. Moreover, because many people were not familiar with this kind of thing, they were not familiar with it.
I don't value it, so I don't want to use it at all, especially the old masters, they don't like it even more.
Zhang Baolin didn't use it when he reported just now, but Qin Zhenhua was different. If he wanted to introduce it to everyone more carefully, it would be absolutely impossible without a projector.
Moreover, he had already prepared it. They had made meticulous preparations for their new diesel engine. These slides were drawn by the most skilled craftsmen in the factory before departure.
This is definitely the most beautiful industrial picture.
The slide projector warmed up for a minute, and then a clear image was displayed on the projection screen at the front. It was a cross-sectional view of an engine that looked complicated but was extremely delicate.
"In order to reduce the size of the engine, and also because we have been producing it for many years and are familiar with it, we still use the V-shaped 60-degree angle structure. The design of the cylinder is roughly the same as before, but,
We have increased the cylinder center distance, so that we can avoid a series of problems caused by the existing cylinder block and have good power improvement potential."
Looking at this picture, Qin Zhenhua explained seriously: "At the same time, we shortened the piston connecting rod, so that it is easier to increase the speed. In order to achieve a compromise, in our plan, the speed of this engine cannot exceed 2,500.
Otherwise, the heat dissipation problem after the speed is increased will not be easy to solve, and the gain will outweigh the losses in the end. Just keep it at 2,400 rpm, or 2,450 rpm."
Qin Zhenhua had just pointed out the design flaws of the Coal Province Diesel Engine Factory, and his design solution happened to be a product that perfectly solved those flaws.
"We plan that the initial power of this diesel engine will reach 735 kilowatts, which is about 1,000 horsepower, and then further increase to 883 kilowatts, which is 1,200 horsepower. For us, this power is more suitable
Advanced tank power standards."
"Huh, that's easy to say. How much can you achieve with this slide of yours? Your satellite is quite large." When he saw this, Niu Shilong finally couldn't help but speak, you
When the upper and lower lips collide, it is easier said than done!
Although Niu Shilong knows nothing about technology, the coal province diesel engine factory has put in so much effort to complete the research on the 537 kilowatt engine. He only knows how difficult it is. As far as the level of a diesel engine factory is concerned, it can be said that it can
I absolutely do not believe in developing this kind of engine.
After saying that, Niu Shilong pointed to the sign in the upper right corner below and said, "What's going on with your name?"
He is a layman, so of course he has to look at it from a layman's perspective. This slide is drawn with meticulous lines, so the details are well displayed, especially in the upper right corner, there is a line of text.
Introduction to 150HB diesel engine.
Niu Shilong cannot name the following letters. People in this era do not learn Pinyin, so they do not know how to call it in Pinyin, nor do they learn English, so they do not know how to call it in English. In short, it must have a name, right?
Just like their project, which is X150, this X means unknown number, which means they have an unknown height, and this HB, what does it mean?
You don't just need to make these fancy.
Qin Zhenhua was also speechless. He couldn't grasp the main problem and could only grasp these unimportant side details. He was really an amateur.
"We gave it a resounding nickname, called Black Panther." Qin Zhenhua said: "We hope that after installing this diesel engine, our tank will be as fast and powerful as a Black Panther."
Qin Zhenhua said casually.
(What does HB mean? East China Heroes don’t know. Some say it is H-shaped steel and B is thin-walled. However, it always feels that it has nothing to do with this engine. It may be a secret. In short, in our book, this
HB, let’s explain it as Black Panther. Black Panther Diesel sounds very domineering. Readers who are about the same age as the Hero of East China should have liked the Black Panther band.)
"Even so, it is not easy to reach 883 kilowatts of power." Zhang Baolin did not pay attention to Niu Shilong's question. What he wanted to talk about was the most important technical issue.
This is not what you say. Technical data cannot be revealed just by talking. Even if your design ensures strength, what about the combustion efficiency of the engine? The engine cannot do so much work, and everything is in vain.
A 1,200-horsepower engine is not so easy to obtain. Look at the British, it took a lot of effort to get it. Moreover, it is regarded as the most advanced thing, and they originally agreed to send it to their side.
As a result, they found an excuse and sank to the bottom of the sea.
Can we do it with our current capabilities? You know, the foundation of this engine is only 500 horsepower after all!
"This is a good question." Qin Zhenhua said, "Then, let's look at the second slide."
The second pillar has always been on the slide. Now that the overall picture has been displayed, of course it is the turn to introduce the picture step by step.
The second picture I printed out shows very few parts, and what is drawn on it is a small part of it, the turbocharger.
"First of all, it's the turbocharger, which directly determines the engine's compression capability."
