Chapter 1353: Visit the Engine Factory

At the beginning, a machine factory was built from scratch on the grassland, so it was built directly with the drawings of the Soviet tank factory, so it is not unusual to find a familiar feeling now.

"Here's our engine production plant." Kartsev led the crowd along the road of the factory, and the first thing they walked into was not the assembly shop, but the engine production plant.

It has always been said that the T-72 tank pursues reliability, and the existing production line is used as much as possible to produce a large [Cuiweiju jks.xyz] volume, which can be seen from the tank engine.

Back then, in order to build the T-64 tank, the Soviets spent a lot of time on the tank engine, which needed to be small in size and strong in power, especially the Soviet tank, which was originally small.

In order to be able to give the T-64 tank a qualified power, the Morozov Design Bureau decided to use a two-stroke diesel engine, which is the only horizontally opposed structure in the tank world, which can be said to be unique.

In order to match the T-64 tank, this engine was developed at the Kharkov Malyshev plant, and for this purpose a new design bureau headed by Professor Alexei Dmitrievich Charomsk was formed to design the 5TD engine, and even a large workshop was built for the production of power units.

It can be said that the investment in this area is considerable, but in the initial stage of the 430 engineering prototype, the reliability of these power systems is quite poor.

Instead of following the old path of the other side, Kartsev abandoned this impractical power system, but continued to develop on the B-2 family of tank engines.

That's right, this is the 12150 series diesel engine of the Eastern powers, which was originally used on the T-34 tank, improved little by little, and has been used until now.

"What you see is our tank engine production line, and it is estimated that you will have a very familiar feeling, which is exactly the same as the production line of the eastern powers." Kartsev led everyone into the factory and explained to the production line: "I don't know if your domestic B-54 engine is still in production?" ”

For the big countries in the East, the B-54 engine is a 12150L diesel engine? Used on 59 tanks? With only 382 kilowatts of power, it's barely enough.

The great powers of the East to improve this diesel engine? That's about 10 percent more dynamic? Used in 69 tanks, and in the USSR? It is also improved on this diesel engine.

"We are still producing this diesel engine." Qin Zhenhua nodded.

There are a large number of 59 tanks in the country? Do these tanks still have to have enough engines to use? Of course, the 59 tank was produced, not the original engine, but improved? A version with an increased lifespan? However, there is no need to mention it here, or listen more, watch more, are you here to learn from the scriptures? I'm not here to introduce my tank.

"This engine, the foundation is quite good? Back then, we were on the basis of this diesel engine? Fuel supply was strengthened, combustion was improved, and the structure was strengthened, resulting in the 427-kilowatt B-55 engine. Kartsev said: "But this improvement is limited after all? Also reduced lifespan? So? We began to develop the supercharged diesel engine, first making the 552 kW B-12-6 engine. At that time, the supercharger was too bulky, and we improved the supercharger and strengthened the structure to create the current 574 kilowatt B-46 engine. ”

At this time, I walked through the engine casting workshop, the engine body inside was being poured, the molten steel was splashed, and Kartsev's spitting stars were also splashing, don't look at his age is not young, but the body bones are quite tough, after all, this old man is still steady when he is more than ninety years old.

"Compared with the previous B-54 engine, the structure is basically the same, the production workshop does not need to move, can produce a new engine, we just to install the supercharger, cancel the eighth main bearing of the original engine crankshaft, so that the engine length is basically the same as the B-54 engine. Suffice it to say that if necessary, we on the T-55 tank, too, can cram such an engine into it. ”

When he said this, he was still very proud. Compared with the original B-54 engine, the power has increased by 50 percent!

When the overall parameters of a certain type of engine are determined, if you want to further increase its power, it is necessary to "inject more fuel", "more air intake" and "increase the cycle rate". "Multi-injection" is limited by the combustion efficiency of the engine cylinder, if the air in it is not enough, the injection is also incomplete, it is closely related to the "multi-intake", in order to take more air, it has to be pressurized; "Accelerating the cycle rate" is to increase the engine speed, but this will make the piston, crankshaft and a series of components worse working conditions, thereby affecting the reliability of the whole machine, except for the Germans, with their industrial base, dare to increase the engine to 2,800 rpm, no country dares to follow suit.

In fact, the B-46 engine was supercharged and the speed was reduced to 2,000 rpm, further improving reliability.

For this improvement, Kartsev is still quite satisfied.

"Excuse me, old man." Qin Zhenhua raised his own question in a timely manner: "With the continuous modification of the tank, the weight will become larger and larger, and the power will become more and more insufficient, so have you developed the next generation of B-46 engines?" Do you have a more powerful engine than it? After all, there must be more powerful engines at the Malyshev plant, right? Maybe it's already 1,000 horsepower. ”

Many of the military industrial enterprises in the Soviet Union are highly secretive, and Nie Qianqian was able to get so much information, thanks to her previous work in the media industry, she met a lot of friends, and collected them everywhere.

However, I don't know, you can Meng, the 5TD tank engine of the Malyshev plant is definitely not the end, seeing that the T-80 tank uses a gas turbine and steals their limelight, won't they chase it back?

Hearing Qin Zhenhua's words, Kartsev frowned, that's right, there is indeed a thousand-horsepower diesel engine at the Malyshev factory, and the engine codenamed 6TD has been reequipped with the T-64, but, how did the other party know?

"How do you know this little comrade?" Kartsev frowned and asked, could it be that there was a leak from the Malyshev factory?

"I guess." Qin Zhenhua said: "Even our big eastern countries have begun to steadily produce 1,000-horsepower diesel engines, and the Soviet Union is a tank power, so how can it not have a 1,000-horsepower diesel engine." ”

Guess? Kartsev had a chill, in the expedition of a big eastern country, Qin Zhenhua was relatively young, so Kartsev didn't care, but now, I found out that when Qin Zhenhua spoke, the people around him were paying attention, what is the identity of this young man?

"How did you guess this little comrade? Where do you work? Kartsev asked.

"A machine factory, my name is Qin Zhenhua." Qin Zhenhua said that he is always embarrassed to say that he is the factory director, right?

"Qin Zhenhua?" Kartsev raised his eyebrows, and suddenly thought of something: "You are the famous director of the First Machine Factory, Qin?" The director of the Qin factory, who developed the 85 tank? ”

"It's despicable." Qin Zhenhua said very modestly.
