Hearing Qin Zhenhua's answer, Kartsev's face suddenly overflowed with a smile: "Sure enough, it's you!" That international tank ranking, is it a trick of yours? ”

The contrast between before and after is really too big, Qin Zhenhua only felt a sigh in his heart, that is, he was shocked, this old man, is he going to trouble me here?

Originally, the other party recognized himself, Qin Zhenhua had a hunch, and if he recognized it, he would recognize it, and the next discussion would be largely about the specific technical aspects of the tank, Qin Zhenhua had already prepared a lot of questions, and he could study them with the other party.

Unexpectedly, the other party actually said this topic, which surprised him very much.

"Ahem, ahem." Qin Zhenhua coughed twice, and then went to see Nie Qianqian, this matter was completely controlled by Nie Qianqian, do you want to push the matter on her? Nie Qianqian knows Russian, and she has been by her side just now, but now she turns her head and goes over, where can she still find someone, Nie Qianqian has disappeared.

"I'm afraid you have a misunderstanding about this." Qin Zhenhua said seriously: "We have also seen the international tank ranking, on the whole, I personally think that it is more fair, after all, T-80, T-72 tanks, there is only a small amount of public information, according to the information to make a comparison, get such a list, it should be correct." ”

Looking at the smile on the other party's face, Qin Zhenhua also knew that the other party didn't really take this matter seriously, after all, before the list came out? Relations between the two countries have not eased, and you did not protest at that time, now? Is it just a small complaint? Does Qin Zhenhua insist on the truth? Personally, I think it's fine.

"For example, take the engine, the current tank engine? If you don't have a thousand horsepower? I'm not embarrassed to show it at all, the engine used in the T-72 tank is only 780 horsepower? So? Naturally, it's a cut off. "What did Qin Zhenhua say? Already made a lot of people look bad? Did we come here to visit? Didn't you come here to slap your face? What should I do if I quarrel with someone for a while?

Qin Zhenhua didn't care, and continued: "So, if you want to be at the top of the list, you have to come up with new equipment, the Soviet Union is a big country?" A military-industrial powerhouse? I don't believe that your 780 horsepower diesel engine has been used for more than ten years? Haven't changed yet? Now, needless to say, 800 horsepower, I'm afraid 900 horsepower diesels are already available? If you have good things, you can't cherish them yourself, take them out and let the big guys see them. ”

Not to mention anything else, first of all, in terms of power, the T-72 is not qualified, just now, Qin Zhenhua just wanted to use the tank on the side of the Morozov Design Bureau to put pressure on the other party, and now that the other party has brought up this international tank ranking, then say it well, what are you embarrassed to take out, good things, take it out for everyone to see!

If not, then I'm sorry, just that motivation, your ranking is already very good.

This can be regarded as the words of the agitated general, and Kartsev's face suddenly became rich, okay, you little guy, you actually came to stimulate us, you students, dare to run to the teacher's head and show off? Okay, let's show you what the teacher really does.

Kartsev couldn't hold it back.

"Of course we have the stuff you said." Kartsev said: "Let's go to the engine test shop, where there is our improved B-84 engine, and the power has been further increased to 840 horsepower." ”

As soon as the other party said this, everyone else couldn't help but want to give Qin Zhenhua a thumbs up, and the Soviets were finally willing to open up some research and development places for us to see.

"This engine, we have improved the new supercharger, the power of the engine has been increased to 840 horsepower, and, if you don't consider the life, it can also be increased to 880 horsepower." "How about this power, if it is used in the T-72 tank, the power per ton has already exceeded the figure of 20 horsepower per ton. Enough is enough, right? ”

T-72 tank, mainly used 780 horsepower diesel engine, which is also the power of the export version, however, the domestic version, has been improving, now, by improving the supercharging device, optimizing the structure of the engine, to get this improved engine, the power is close to 900 horsepower, is already quite strong, after all, compared with the tanks of other countries, the weight of the Soviet tank is not large.

Facing Kartsev's introduction, Qin Zhenhua still shook his head with a big grin: "No, no, I don't think it's enough, you guys are on the wrong path." ”

The crowd was stunned again.

In front of me, it is the most important tank engineer of the Soviet Union! The Soviets are teachers, we are students, we are here to investigate the learning experience, are you here to slap the face and pick a thorn?

"Wrong?" The expression on Kartsev's face was obviously difficult to look at.

"That's right, it's wrong, I think, you've gotten to 880 horsepower, and you've got to the end of the supercharger, and if you want to get more power, you're going to have to use the exhaust gas turbo."

Qin Zhenhua was here, and began to point out the country and talk eloquently.

Mechanical supercharging, for a long time, is the main way to improve the power of the engine, in the engine through the belt to drive a supercharger, directly to the engine to add more air intake, quite direct, but at the same time, the weakness is also there, since it is driven by the engine, it is a waste of power.

Therefore, no matter how strong the performance of mechanical supercharging is, it will eventually be replaced by turbocharging, which uses the exhaust gas of the engine exhaust pipe, which is good for improving the power and thermal efficiency of the engine, so the West has long eliminated mechanical supercharging and entered the sequence of turbocharging.

His words were simply stepping on the other party, originally everyone thought that the other party would be angry, who would have thought that the other party had a solemn face, but he did not look angry: "Exhaust gas turbocharging? Kartsev muttered: "I didn't expect that you Eastern powers have chosen a better path than us." ”

This sentence actually echoed what Qin Zhenhua said!

The Soviet mechanical engineers are also quite powerful, so now, they have also discovered that the use of supercharging has come to an end, and their B-84 and B-88 engines are already the limit, representing the highest level of supercharged engines, and also representing the end of supercharging.

In their plan, the development of the exhaust gas turbocharged engine has begun, and the foundation of this engine, if you want to be able to increase to 900 horsepower, or even 1,000 horsepower, you can only rely on the turbocharged engine scheme.
