The first thousand three hundred and fifty-five chapters are very happy to talk
In the technical field, Kartsev is quite focused. Now, Qin Zhenhua has spoken out the solution to use exhaust gas turbocharger, which is also what they are developing, so he immediately became interested.
In the field of technology, right is right, wrong is wrong. In the past, they kept following the mechanical booster route. When they walked to the present, they found that it had reached its end. Therefore, the plan he said to Qin Zhenhua at this time was completely complete.
Agree.
Qin Zhenhua was actually shocked at this moment.
The Eastern Powers are also renovating the B2 diesel engine. Their own 12150L diesel engine, the Soviet B2 diesel engine, are all ancestors. In the Eastern Powers, they first increased the power to 730 horsepower, and then further increased to 800 horsepower.
However, after increasing to 800 horsepower, we had already encountered a ceiling, and the power had reached its limit and could not be improved any more. At that time, it was even proposed by Qin Zhenhua that using the original body to reach 800 horsepower was the limit.
Who would have thought that the Soviets' technical level was strong, and in terms of individual aspects, it was not the best, but when integrated, the Soviets were definitely the strongest. The ceiling of 800 horsepower that they believed was here?
Don't care? It's not enough to increase to 800 horsepower, 84? 88? It's almost 900 horsepower.
However, if nothing unexpected happens, nine hundred horsepower is the limit.
Now, when he looked at the other party with an expression of admiration, Qin Zhenhua decided to continue to deceive the Russians? See what the other party could say.
"Yes, the road we chose is easier to walk, and we also know that when the power is increased to 900 horsepower, the original body of the B-2 engine has been fully explored, and we want to further build on it
It will be quite difficult to improve."
These were obtained after taking a detour. The coal-provincial diesel engine factory planned to excavate the body of the B-2? The X150 engine was built, but it ended in failure? Now, Qin Zhenhua knows that since the B-2 diesel engine is old
Designed by the Russians, they naturally knew that the potential of this machine had been exhausted.
Sure enough? Hearing Qin Zhenhua's words? Kartsev's expression was dim: "Yes? You are right. Even if we use exhaust gas turbocharged engines and reach 900 horsepower, it is already the limit. We will continue to improve.
There will be many problems with potential.”
Sure enough, although the old Russians have a solid foundation and strong integration ability, they have reached their limit now. Qin Zhenhua said with a smile: "Our diesel engines focus on compact size, but after the compact size, they bring bad heat dissipation problems.
The inherent defect of the B-2 diesel engine is that the cylinder center distance is too small and the stroke is large at the same time."
This is not a leak. The Russians must also know the flaws that our side knows. So what we are saying now just shows that our side's technology is also advanced enough, and everyone is on the same level, so,
There are more opportunities for communication between each other.
When I heard that the cylinder core was small and the itinerary was large, Kartsev's eyes showed a strange look: "I really didn't expect that you have thoroughly understood the B-2 diesel engine and are well aware of its defects.
You students are already able to study independently without the teacher. It's really good. The disadvantage is what you said. So, how do you plan to solve it? Or, how did you solve it? The 85 tank is used.
A diesel engine with a thousand horsepower.”
The Russians are currently using a 840-horsepower diesel engine, which uses exhaust gas turbocharged engine. It is currently under development. However, if we continue to increase the power, these two problems encountered have become increasingly urgent.
.
Their own motivation has not reached one thousand horsepower, and the Eastern Power has already done it. Therefore, they are very envious and look forward to the guests from the Eastern Power to introduce their valuable experience.
"If the cylinder core distance is small, then increase the cylinder core distance and the stroke is large, then reduce the stroke. Specifically, in terms of stroke, we have shortened the piston stroke of 180 mm to 160 mm, so the vibration problem of the body is huge.
The ground has been lowered." Qin Zhenhua said.
"That's right, it's 160mm!" Kartsev's face was already filled with surprise when he heard Qin Zhenhua's words. What's this called? The heroes saw the same thing! The Russians are on the road to improving their B-2 diesel engine
, also knew these problems, so they shortened the piston stroke. The specific data also shortened 180 mm to 160 mm, which is simply the same technical route.
Kartsev's voice was filled with joy: "By adopting this method, we can increase the engine's power to 1,200 horsepower! We are currently under pre-research, and when the research and development is successful, our T-72 tank will be
The engine compartment can be stuffed into a 1,200-horsepower engine without any modification. At that time, who can still find out the problem of our T-72 tank's weak power?"
This has been leaked, but since the Eastern powers have also had the same technical route, it is not impossible for everyone to communicate. Now, his face is filled with joy and he is very happy.
The guests of the Eastern Power are indeed frank enough. Their technical routes can be said without reservation. Of course, they can also say a little about their own approach. Anyway, these are not particularly important. Let's talk about them.
Now, they are much more open and not as strict as they used to be.
When Qin Zhenhua heard these words, he felt a little more emotion. The Russians are indeed Russians.
In order to achieve a power of 1,200 horsepower, increase the distance between the cylinder center and reduce the itinerary, all of which have been done. Now, the power level of 1,200 horsepower has been achieved. But the Russians are planning to reduce the itinerary.
Increase the power to 1,200 horsepower!
I used to pre-research, and 800 horsepower was already the limit of the 12150L engine. It must be greatly modified. For the Russians, only one modification is enough.
Although the other party is only planning, for the Russians, their basic skills are quite solid. Through calculations, they can be counted as almost the same, which refreshed Qin Zhenhua's concept.
Wu Ruihua, who was standing beside him, couldn't help it: "If you don't increase the cylinder center distance and just reduce the piston stroke, you can reach 1,200 horsepower?"
Comparing people with others is so annoying. When we think that the ceiling we think has to be raised several layers upwards, this is the gap in the industrial foundation.
