Because no one is concentrating on technology, it is difficult for all factories to meet the strict technical requirements of parts, components or wholes, and the materials supplied by other factories are becoming more and more substandard, and the quality of military products is strictly declining.

Now it is good that the engine power of the tank can reach 80% of the nominal power.

Because the quality of the tanks is so poor, they often lie on their stomachs during training, and even cause casualties, which makes the army leaders extremely annoyed, and the army is naturally unwilling to accept these old men who let people wait.

As a result, the factory's orders are greatly reduced, the factory's efficiency is lower, the factory is more reluctant to invest in research, and the quality of the products produced is poor,......, thus forming a vicious circle.

In the original history, this situation has been maintained for a long time, and many problems with military products have been concentrated in the Sino-Vietnamese border war: artillery shells cannot explode, rifle shells are jammed, and tanks cannot be opened.

There is such a scene in the movie "Garland Under the Mountain": the recoilless gunner "Little Beijing" died because of the dud fire of the shell.

This situation did not gradually change until about 4 years ago.

Although this plant does not produce engines as a whole, they produce several major components that have a significant impact on engine performance. For a conscientious technician, Deputy Chief Engineer Huang, who knows the inside story, is anxious. If there is a way to increase the power of the engine at this time, it can make up for some defects of the engine in a certain way.

Don't make this five percent smaller, people who understand technology know that even if it is increased by one percent, its significance is heavy, which can make the overall performance of the tank more coordinated and greatly improve its combat performance. What's more, the power increased by this method is more than five percent, and Guo Zhuocheng didn't dare to say too much to scare them.

The reason why Guo Zhuocheng risked being suspected of saying this method was that he didn't want the soldiers to suffer too many casualties due to weapons in the border war the year after that, and it was also a meritorious thing to save the lives of a few young soldiers, so what was it to take some risks himself?

Guo Zhuocheng said matter-of-factly: "According to legend, on the Soviet-German battlefield of World War II, at the beginning, the German army was like a fierce tiger all the way through the hurdles and defeated the Soviet Red Army. However, it did not take long for the Red Army to gain a firm foothold and begin a counteroffensive, turning the tide of the battle through the victories in the Battle of Guò and the Battle of Moscow, and killing the German army in defeat. You know no, in the process of the great victory of the USSR, there was a weapon that played a major role. What is it? T-4 tank! I'm not wrong about this, am I? ”

Although Deputy Chief Engineer Huang was depressed, he still nodded and said, "Everyone knows this." ”

Guo Zhuocheng said: "Everyone knows the course of this war, and they also know the T-4 tank. But you don't necessarily know that the T-4 was developed by the Soviets because of a misintelligence. Right? ”

"Misinformation led to the development of T-4? No way? Sure enough, Deputy Chief Engineer Huang and several workers who came around didn't know, and they all looked at Guo Zhuocheng curiously.

Guo Zhuocheng continued to pretend to say: "At that time, a Soviet agent sent back information from Germany that 'Germany is developing more powerful heavy tanks', and the Soviet tanks at that time could not match it. As soon as the Soviet leaders heard this, they paid it back, how could they make the tanks of fascist Germany stronger than ours? Therefore, Comrade Stalin gave an order and ordered the famous tank designer Koshkin to immediately develop a tank with greater power and protection. This is how the T-4 tank was released.

Ke Xijin is a very cowhide, cowhide is very powerful, he only took more than two years to develop the T-4.

As soon as the Soviet-German war broke out, the Soviet army discovered that Germany did not have any large tanks at all. Those who participated in the war were tanks known to them. However, the top leaders of the Soviet army were not angry, but rejoiced, because the latest T-4 developed by the Soviet Union was invincible on the battlefield, and the Soviet tank division was able to sweep the German tank division. Germany can only strike a balance by relying on numerical superiority.

The Soviet leadership is one, the current T-4 is too strong, the production cycle is long, the cost is large, the driver requirements are strong, there is a sense of wasting resources, and it also affects the speed of tank construction and the speed of tank divisions into armies.

After a period of weighing, Comrade Stalin resolutely ordered: "Your R&D personnel must give me a drastic reduction in the cost of the tank, simplify the manufacturing process, simplify the driver's requirements, and allow you to reduce its performance a little, but the speed of construction must be accelerated." One of his goals for the technicians was: our tanks should not be inferior to the German tanks in terms of quality, but they must surpass the German ** team in quantity.

As a result, the components of the T-4 tank were greatly simplified, and the process was greatly reduced. In terms of cost, it took 94 rubles to build a T-4 in 269500, and in two years its cost was reduced to 5000 rubles, almost half. And women and children in general, even wounded soldiers and the elderly, can be put into production. ”

The surrounding workers listened with relish, and some lamented that the Soviets were too good, and in just over two years, they developed a famous tank. We have been imitating for so many years, and it is still not good to imitate.

Deputy Chief Engineer Huang's brain is much smarter than that of the surrounding workers, and after listening to Guo Zhuocheng's words, he thought of something, so he asked tentatively: "You mean that our current engine may be copied on their simplified version?" ”

Guo Zhuocheng said: "No! ......, but about the same. ”

Deputy Chief Engineer Huang humbly asked, "So how do we change?" ”

Guo Zhuocheng said: "There are many ways to increase the engine power, such as supercharging, such as increasing the compression ratio, such as increasing the cylinder diameter, such as increasing the extreme speed of the engine, etc., which are too complicated for our factory, the investment is large, and it is difficult to succeed for a while." ”

Finally talking about technology-related issues, Deputy Chief Engineer Huang nodded again and again: "Yes, yes,......"

Guo Zhuocheng said: "Reasonable selection of engine valve timing to ensure the best inflation efficiency can improve engine performance. If we can learn from the system that the Soviet Union began to design, we can increase the intake charge, so that the charge coefficient increases, and the torque and power of the engine naturally increase. ”

It is a dexterous control system that takes a mechanical and hydraulic approach to achieve its function. It is not comparable to the computer-controlled "variable valve timing" technology of the previous life, but it is much better than the traditional engine without this system.

In fact, this system was not designed by the Soviet Union, but by Germany in the previous life, and now it appeared here five years in advance.

Guo Zhuocheng's purpose in fabricating this story is to transfer the flowers and trees, and put the invention rights of this system on the Soviet Union, so as to reduce the suspicion of others.

He picked up an iron bar and drew a schematic diagram of the principle on the ground, explaining it as he drew it.

The others didn't understand and didn't know if the little kid was telling the truth or the fake, so they scattered a little.

Deputy Chief Engineer Huang became more and more frightened the more he listened, his eyes stared at the moving iron bars on the ground, and his ears listened to what Guo Zhuocheng said, for fear of missing an action or a word. ~！
