The engine reflects the level of a country's industrial level, and even a small wear-resistant coating on the engine can only be made after the country's industrial level reaches a certain level, not to mention other precision machining components, research and development of various advanced materials, and other technologies.

The tank engine is the pinnacle of the entire piston engine, and it is actually very difficult to put it in terms of the current domestic industrial base.

Therefore, the best way to do this is to concentrate the strength of the whole country and integrate it into research and development.

However, each factory has its own interests, and it is not easy to integrate them, and blindly under the auspices of the state and jointly engaged in it will also form a lot of unfavorable situations, such as passing the buck to each other, complaining about each other, and asking for funds but not working.

Only competition will lead to progress, and this was already vividly reflected in the last tank bidding. After bidding, the cost has been reduced, and the technological progress has been obvious, which is much better than the previous era of big pot rice.

Therefore, it is actually very difficult to say that everyone is working together to engage in research and development.

In fact, it is not right to say that there is no cooperation between each other, as far as the current engine is concerned, the main components above, turbochargers, oil pumps, and fuel injectors, these are actually processed by a machine factory, which is much higher than the accuracy of the coal provincial diesel engine factory's own production.

Everyone is actually already uniting.

However, this is only a small number of alliances, and now, if we want to say that we are working together on a new engine project, there will still be a lot of problems, a lot of resistance, and we are waiting.

One of the first big problems, of course, is the route dispute, when it was planned, there were three routes, won the national investment, is the project of surveying and mapping to imitate the German 8V331 engine, this project, is a national key project, code 8V165, now, is developed by the engine.

X150 and 150HB engines, these two engines, are currently self-funded research and development, which means that the pressure on their two factories is also very great.

Now, Zhang Baolin said that Qin Zhenhua is naturally interested, but he feels that there are quite a lot of problems to face in this cooperation.

"Can you take a look at your engine development?" Zhang Baolin asked.

"Absolutely." Qin Zhenhua said.

A branch of a machine factory has set up an engine research and development department, and this department is led by Qin Zhenhua, after all, the engine research and development project was proposed by Qin Zhenhua, and after coming back, for various reasons, he was excluded from the research and development of the second-generation tank, and he can only take the lead and engage in the research and development of the second-generation tank.

This R&D workshop, and the machine tool processing workshop, are almost next to each other, when Zhang Baolin walked in, the first thing that caught his eye was two screens that were constantly beating characters.

"Computer?" Zhang Baolin looked at these things and couldn't help but ask in surprise, "Where did you get it?" ”

In this era, in the big countries of the East, the computer is definitely a new thing, and Zhang Baolin would never have imagined that a machine factory would have such a tall thing as a computer.

"Of course I bought it." Qin Zhenhua said: "At the end of last year, we purchased a batch of computers from abroad through the computer institute, and we had these computers to calculate various data of diesel engines, which was like a tiger with wings." ”

Scientific research is inseparable from computers, modern factories, is also inseparable from computers, in the past few years, Qin Zhenhua has been thinking about this matter, their CNC machine tool processing, if there is a computer, then you can directly use the computer to draw, into a program, into the CNC machine tool computer, instead of as now, one by one into the code.

It's a pity that there has been no such strength before, until the end of last year, the new leadership of a machine factory came to power, and at the same time an export agreement with the desert area was reached, a machine factory suddenly had a sufficient source of funds, so it is normal to use a small part of this batch of funds to buy a few computers.

Didn't pass through the system, this is also Qin Zhenhua's precautions, now, the whole industry is red at a machine factory, if you purchase through the system, I don't know who will intercept it, through the computer institute, they got this batch of Apple-2 computers, at present, all of them have been used.

Zhang Baolin's eyes widened, looking at the characters that were beating inside, not knowing what was being calculated, and at this time, Qin Zhenhua walked over and entered a few commands inside.

Then, on the screen, a figure appeared, that figure is a perspective commonly used in mechanical drawing, one by one, due to the problem of resolution, some graininess, especially the arc part, looks like a sawtooth, but the moment this figure appeared, Zhang Baolin saw it.

This is an air roof, and this air top plate looks different from the previous ones.

"Although we are improving the existing engine, we plan to take a positive path of research and development, so we have to do a lot of calculations, in the past, we could only use a slide rule, but now, we finally have a computer, we use it to assist in design and calculation." Qin Zhenhua introduced on the side: "The valve mechanism of the engine is very important, especially after adding the supercharger, the valve mechanism is required to be able to channel all the air through in time, and we plan to use the four-valve structure, which is still an innovation." ”

To develop positively, a large amount of data must be calculated, which is what a machine factory has come up with at present!

Zhang Baolin was shocked.

The Coal Provincial Diesel Engine Plant is also doing it, but how did they do it? Use your own experience to make improvements on the engine, test it after the improvement, and solve the problem when it arises.

In this process, in fact, they are not aware of the real situation, and often solving this problem will cause other problems and affect the whole body.

This is a disadvantage of surveying and mapping imitation, the original according to other people's surveying and mapping imitation, may be able to pass, but once changed, it will cause a chain reaction.

It's not that they haven't thought about positive research and development, but positive research and development requires courage.

I used to think that I was an expert in this field, but today, I realize that my vision and pattern are still too small.

The one who can really lead the team and finally succeed should belong to people like Qin Zhenhua.

Looking at Qin Zhenhua again, his eyes had changed.
