Chapter 663 Tank Has a Big Heart (Part 2)

In fact, domestic tanks have always been troubled by the engine. If the power is not high enough, they cannot be made bigger and heavier. Therefore, for a while, they can only be modified with five pairs of wheels. Later, there was Type 99, but it was still fettered by the engine.

The engine used by the current Type 99 tank is a domestically produced 1,200-horsepower diesel engine. Although the overall design is very advanced, there are still certain deficiencies in maneuverability.

It is not that there is no way to buy high-power diesel engines from abroad, but NATO countries led by the United States have collectively banned sales to China in this field. Even if there are occasional civilian 1500-horsepower engines, their use is strictly restricted and they are not allowed to be used for military purposes. This also makes the country have to make up its mind to solve the heart problem of tanks.

It only took Guo Tailai and Long Fei more than a month to come up with a series of diesel engines, which is absolutely ridiculous in the eyes of some people who know this for the first time. Especially in the eyes of some old experts who have been studying engines all their lives, this is simply a joke.

Still the same sentence, learning is a down-to-earth thing, and the same is true for research and development. It is definitely not a good thing to lack the foundation overnight. You can come up with a series of designs in a month, so what do you want those people who have studied for decades?

Zhao Xiangbei asked these domestic diesel engine experts to come and check and accept it, but the experts did not refuse. Zhao Xiangbei said before that this is an additional engine option for our domestic tanks. If it succeeds, it will definitely be a good thing. They are all old experts who have dedicated their lives to the country. How could they not understand the benefits of success in this matter?

However, in order to prevent Guo Tai from cheating here, they always bring their own testing equipment when they come to check and accept. This is a responsible attitude, not against anyone. In fact, Zhao Xiangbei didn't tell these people at all that the designer of the engine was Guo Tailai. He only said that it was for acceptance, but he didn't say whose design was accepted.

In the military industrial group, there are many such things, and it is normal for designers to keep secrets. The experts had gotten used to it, and without asking a word, they followed Zhao Xiangbei all the way to the small factory where Guo Tailai and the others developed the engine.

Seeing such a humble small factory, the hearts of several experts were half cold. Such a small township enterprise-level factory may design and manufacture a small-displacement engine, and the parameters may be very good, but if you want to make a series from large to small, I am afraid that the possibility is not the same as that of the Huaxia Football Team. It will be as low as winning the next World Cup.

Not only that, before going in and saying a few words, the tall and thin designer was taken away by a lieutenant colonel. Although there must be something important, can't the timing of this kind of acceptance be staggered? Such a young designer, anyway, the hearts of the few experts who were half-cooled at the moment were another quarter colder.

When Long Fei enthusiastically greeted these old experts to start working and saw the real thing, only a quarter of his heart remained uncooled, and then another eighth of it became cold again, and only one eighth was left.

How can the size of these engines be so small? According to the above introduction, the average displacement of each engine is much smaller than that of the same type. Such a small engine, how much horsepower and torque can be expected, isn't this a toss?

Fortunately, after understanding the principle of Long Fei's explanation for a while, the experts were relieved. At least the principles of these engines can be explained, and they can still operate normally. I dare not say how excellent the performance is, but at least this is indeed a complete series. There may not be a chance for military use, but in the civilian field, such a small-sized engine, even if the power is a little lower, can be adapted to many occasions. This can be said to be the only good news I got today.

But since it is going to be checked and accepted, there is no delay. The instruments are ready, the debugging is done, and then the parameters of the engine are measured one by one.

Starting with the smallest size, when the machine was connected to the dynamometer, several experts looked at several parameters of this engine provided by Longfei. After only a few glances, several people burst into laughter. Here, except that the size is definitely not a problem, everything else is an exaggeration. Such a small size is so much smaller than the same type made in China, and the power is 40 to 50% higher. How is it possible?

But when the speed, power and torque curve of the first smallest engine came out, the faces of several experts all changed. The parameters presented by this young man, Long Fei, were not fake?

You know, this is their own dynamometer, and it has never been tampered with. The power and torque measured in this way are not false figures, which is really amazing!

"Immediately, change to the 1,500-horsepower model." One of the experts was researching tank engines. Seeing the result curve, without a word, he asked someone to change the machine immediately.

The size of this 1500-horsepower ten-cylinder diesel engine is smaller than the 1200-horsepower one currently used on the 99 tank. If the power and torque data are true, he can't even imagine that the 99 tank will be replaced by this engine. What an excellent performance.

There was no help from Long Fei and the others in the test. They were all brought in by the experts themselves, just because they were afraid that they would cheat. But now, they couldn't wait any longer.

The ten-cylinder diesel engine started to run, and the motor on the dynamometer began to rotate. As the speed increased all the way, the console over there also generated a series of speed, power and torque curves. After half an hour, the detailed data was finally released, and at this moment the tank engine expert was already trembling with the result curve that came out earlier.

There is definitely no problem with a power exceeding 1200 horsepower, and the maximum torque at low speeds also exceeds that of the tank engine currently in service. Now we only need to wait for the highest power to be released to know the final result. When another expert handed him the final test results, seeing the 1538 horsepower data above, he couldn't help but get red eyes.

The engine power of tanks in the United States and Germany is almost all 1500 horsepower. For this reason, an embargo and blockade of diesel engines with this power was imposed on Huaxia. Huaxia had to use a 1200 horsepower engine to push out the Type 99 tank first.

Now, he personally tested this 1500-horsepower engine. The data will not be problematic. The size is still so small and fuel-efficient. It can be said that as long as it is modified according to the size, it can be directly used on the 99 tank! Our tanks also need to have a big heart!

"Don't worry!" Seeing him like this, another not-so-young expert actually felt the same in his heart, but he still persuaded him: "There is another 2,000-horsepower model, and we will have fun together after the test is completed!"
