"That's the advancement of technology." Facing the 80 tanks that had been assembled, Qin Zhenhua's face was full of smiles.

Coal Province Diesel Engine Plant, through the use of turbochargers, the power of the engine increased to 730 horsepower, and now, the tank in front of you, is going to be taken out to parade, and the supercharger used above is the latest supercharger developed by a machine factory, it is under the effect of this supercharger, the power performance of the engine, further improved to 800 horsepower!

"Yes, if you want to talk about this technology, it is also related to the Steyr technology we introduced." Wang Erzhu on the side also had mixed feelings: "Pulse boosting technology is so powerful." ”

Now, the potential of the engine is determined by the level of the supercharger, and the higher the performance of the supercharger, the more air can be pumped into the cylinder.

In the past, it could be called a constant pressure turbocharging system, which integrated all the exhaust pipes and then introduced the turbine. Although each cylinder is exhausted alternately, the volume of the exhaust pipe is relatively thick, and when it reaches the turbine blades, the pressure is almost constant, so it is called a constant pressure boosting system.

And now, this pulse pressurization technology, in order to improve the utilization rate of energy loss in the constant pressure system, the exhaust received by the constant pressure turbine is stable, these exhaust after the discharge of the cylinder, first carried out an expansion, at this time, the exhaust energy has been wasted, only the use of about ten percent of the exhaust energy, even if it is running at full speed, it is not more than 30 percent.

The pulse pressurization, as the name suggests, is the use of exhaust gas discharged from one cylinder, the exhaust gas is discharged alternately, and the pulse is formed, which is directly introduced into the turbine blades without expansion and depressurization, so that the exhaust pipe is short and thin, and the volume of the exhaust pipe is minimized, so that the exhaust gas discharged by the engine directly and quickly enters the turbine to expand and do work, and the energy of exhaust expansion is also utilized.

In this way, the turbocharger is more efficient.

Steyr heavy trucks are also in the latest engine, the application of this pulse supercharging technology, and then, this supercharging technology, is used in this tank engine.

The tank engine reached 800 horsepower, which is an innovation, a catch-up and surpass, and under such power, the 80 tank will have a more abundant power reserve, even at low speeds, it also has good torque.

Now, looking at these assembled tanks, Qin Zhenhua is excited, according to the plan, these tanks are going to participate in the military parade.

"Uncle Luo?" At this moment, there were footsteps behind him, and when Qin Zhenhua turned his head over, he saw Luo Ronggen, and at this time, the expression on his face was a little strange.

"Made?" Luo Ronggen asked Qin Zhenhua.

"Yes, our factory has gathered skilled craftsmen to produce these equipment." Qin Zhenhua happily pointed to the tank that had just been assembled.

"Oh, congratulations, but I have some not-so-good news here." Luo Ronggen's face was not very good at this time, but what should be said was always to be said, and he had no idea of hiding it.

"After all, the 80 tank belongs to our new equipment, and the superiors still have certain doubts about the reliability of this equipment, in order not to have accidents, so the superiors do not plan to arrange the 80 tanks into it." Luo Ronggen said.

"What?" Hearing this, everyone was stunned, everyone worked hard to catch up with work, this kind of thing, it is normal to prepare for it one or two years in advance, but I didn't expect that the superiors still didn't trust them.

After all, there has been no military parade for more than 20 years, and this military parade is of great significance, and there must be no problems.

"So, you have to be mentally prepared." Luo Ronggen said: "I will also try my best to introduce the reliability of our tank to my superiors, and strive to make the superiors change their views." ”

"No, Uncle Luo." At this moment, Qin Zhenhua spoke: "There is no evidence, and what you just say is not enough to make your superiors believe it completely." We're going to have to do it. ”

If the superiors had changed their views and opinions just by relying on some paper information, then Luo Ronggen would have done it a long time ago, and now, since the superiors still doubted, there was a reason for their doubts.

Suspicion is not terrible, let's find a way to dispel the concerns of our superiors.

"Are you going to invite your superiors over?" Luo Ronggen asked: "The superior leaders have a lot of opportunities, I'm afraid they don't have time!" ”

If you let the leader come to see it in person, it will naturally be the best, but how much face does a machine factory have to let the superior leader come over in person?

That's not easy.

"Yes, Zhenhua, the idea is very good, but it is difficult to implement." Zhu Lao said on the side.

"No, no, you misunderstood me." Qin Zhenhua said: "Zhu Lao, Uncle Luo, have you ever heard of the T-34?" ”

For people who build tanks, if they don't know the T-34, it's like the French don't know Napoleon, and the Americans don't know Washington, which makes people feel ridiculous, and now, when Qin Zhenhua talks about the T-34, the big guys are a little strange, why do you say this?

During World War II, the T-34 relied on its simplicity and sturdiness and ease of mass production, but it appeared widely on the battlefield, bulldozing the whole of Europe by relying on the torrent of armor, forming the T-34 crisis that caused headaches for the Germans. Until now, the tactics of the Soviets are actually still following the combat plan of the T-34, and the T-72 is actually equivalent to a replacement for the T-34.

Now, when Qin Zhenhua talks about the T-34, everyone is just puzzled, why did he bring up this matter?

"Back then, when the T-34 first came out, it was unknown, and the Soviet Union's top brass didn't look down on this tank at all, after all, the Kharkov Comintern plant at that time was only an inconspicuous factory in the Soviet Union, and there were all kinds of struggles, so the T-34 had no future at first, and Mikhail Koshkin, the tank designer at that time, also knew this deeply."

When Qin Zhenhua said this, Zhu Lao had already understood: "You mean, let's have a long-distance test?" ”

Of course, Zhu Lao knows about this legendary thing.

At the same time, Zhu Lao also knew Qin Zhenhua, so he captured Qin Zhenhua's thoughts at once.
