In the field of technology, Kartsev is quite focused, and now, Qin Zhenhua has said that the plan for using exhaust gas turbocharging happens to be developed by them, so he immediately became interested.

In the field of technology, right is right, wrong is wrong, they used to take the route of mechanical supercharging, and until now, they found that it has come to an end, so he completely agrees with the plan that Qin Zhenhua said at this time.

Qin Zhenhua's heart at this time was actually shocked.

The eastern powers are also transforming the B2 diesel engine, their own 12150L diesel engine, that is, the B2 diesel engine of the Soviets, are an ancestor, here in the eastern powers, the power was first increased to 730 horsepower, and later further enhanced to 800 horsepower.

However, after increasing to 800 horsepower, it has already encountered a ceiling, the power has reached the limit, and it can no longer be improved, at that time, it was even proposed by Qin Zhenhua, using the original body, reaching 800 horsepower is a limit.

Who would have thought that the technical level of the Soviets was strong, in terms of individual aspects, or not the best, but when integrated, the Soviets were definitely the strongest, and they thought that the ceiling of 800 horsepower? Here, I don't care at all, it's not enough to increase to 800 horsepower? Eight hundred and four? Eight hundred and eight? It's close to 900 horsepower.

However, if nothing else, 900 horsepower is the limit.

Right now? Looking at each other with an expression of admiration? Qin Zhenhua decided to continue to talk to Lao Maozi to see what the other party could say.

"That's right, the path we've chosen is easier? And? We know that too? When the power is increased to 900 horsepower? The original body of the B-2 engine? The potential has already been tapped? It will be quite difficult to build on it. ”

These were obtained after their own detours, and the Coal Province Diesel Engine Plant planned to excavate on the body of the B-2 and build the X150 engine, but it ended in failure? Right now? Qin Zhenhua knows? Since the B-2 diesel engine was designed by Lao Maozi? Naturally, they knew that the potential of the mech had been exhausted.

Sure enough, hearing Qin Zhenhua's words, Kartsev's face had a gloomy expression: "Yes? You're right, even if we use an exhaust gas turbocharged engine, after reaching 900 horsepower, it is already the limit, and if we continue to improve the potential, we will encounter a lot of problems. ”

Remember the URL

Sure enough, although Lao Maozi has a solid foundation and strong integration ability, but now, it has reached the limit, Qin Zhenhua said with a smile: "Our diesel engine pays attention to compact size, but after the compact size, it brings the problem of poor heat dissipation, and the congenital defect of the B-2 diesel engine is that the cylinder center distance is too small and the stroke is large. ”

This is not a leak, the defects that he knows, Lao Maozi must also know it, so what he is saying now just shows that his technology is also advanced enough, and everyone is standing at the same level, so there are more opportunities for communication between each other.

When he heard that the distance between the heart of the cylinder was small and the stroke was large, sure enough, Kartsev's eyes showed a strange look: "I really didn't expect that you have thoroughly eaten the B-2 diesel engine, and you know its defects well. The shortcomings are what you say, so how are you going to solve them? Or rather, how did you solve it? The 85 tank used a 1,000-horsepower diesel engine. ”

Lao Maozi is currently using a stable diesel engine of 840 horsepower, using an exhaust gas turbocharged engine, which is currently under development, but if you continue to improve the power, these two problems have become more and more urgent.

Their own power has not yet reached a thousand horsepower, and the Eastern Powers have already done it, so they are very envious and look forward to the guests from the Eastern Powers to introduce their valuable experience.

Specifically, in terms of stroke, we have shortened the piston stroke of 180 mm to 160 mm, so that the vibration problem of the body is greatly reduced." Qin Zhenhua said.

"That's right, it's 160 mm!" Kartsev heard Qin Zhenhua's words, and his face was already full of surprise, what is this called? Heroes see the same thing! Lao Maozi also knew these problems on the road to upgrading his B-2 diesel engine, so they shortened the piston stroke, and the specific data also shortened 180 mm to 160 mm, which is simply the same technical route.

Kartsev's voice was filled with joy: "In this way, we will be able to increase the power of the engine to 1,200 horsepower!" We are currently in the pre-research, and when the research and development is successful, the engine compartment of our T-72 tank can be stuffed with 1,200 horsepower engines without modifications, and when the time comes, who can find fault with the weak power of our T-72 tank? ”

This has been leaked, but since the big country in the east already has the same technical route, it is not impossible for the big guy to communicate, and now, with joy on his face, he is very happy.

The guests of the big eastern countries are really honest enough, their technical routes, they can be said without reservation in this way, then of course he can also talk a little bit about his own practices, anyway, these are not particularly important, besides, now, they have opened up a lot, not as strict as in the past.

When he heard these words in Qin Zhenhua's ears, he sighed again, Lao Maozi, it is indeed Lao Maozi.

In order to achieve 1,200 horsepower, we have increased the cylinder center distance and reduced the stroke, all of which have been put together, and now we have achieved a power level of 1,200 horsepower, and Lao Maozi, just by reducing the stroke, intends to increase the power to 1,200 horsepower!

I used to pre-research, 800 horsepower is already the limit of the 12150L engine, it must be overhauled, in Lao Maozi's place, only one is enough.

Although the other party is only in the plan, for Lao Maozi, the basic skills are quite solid, and through calculation, he can be counted as eight or nine, which refreshes Qin Zhenhua's concept.

Wu Ruihua on the side couldn't help it: "If you don't increase the cylinder heart distance, just reduce the piston stroke, can you reach 1,200 horsepower?" ”

People are more angry than people. The ceiling we think we think is several floors up to Lao Maozi, and this is the gap in the industrial base.
