"On the whole, it is similar to our B2 series engine, so it is not difficult to overhaul."

Uruihua is proficient in engines, and now, this engine has been hoisted out, and a group of people have begun to study it.

In order to ensure that the test of the 69 tank can be carried out smoothly, Qin Zhenhua brought over the elite soldiers, and the test in recent days has confirmed that the performance of his 69 tank is good and has good adaptability in the desert area, so these technicians, as long as they carry out routine inspection and maintenance every day, it is enough, and there is enough time to overhaul the engine for them.

At the same time, everyone is also interested in studying this engine.

If you study it, you can find that it is almost the same as your own engine.

Soviet tank engines, inherited from the T-34, have not changed much in this structure for decades, and the power is constantly improving.

Moreover, the path taken is almost the same as its own, by increasing the fuel supply, the power is increased from 520 horsepower to 580 horsepower, and then by supercharging, the power is increased to more than 700 horsepower.

It's just that the domestic turbocharging method was used to increase the power to 730 horsepower, while the Soviets used mechanical supercharging to increase the power to 780 horsepower.

However, this has come to an end, and it is almost impossible to continue to improve.

"In order to install the supercharger, they eliminated the eighth main bearing of the original engine crankshaft, so that the engine length was basically the same as the original engine. Compact structure, good dry. "However, it is precisely because of this that the original structure is adopted, so heat dissipation has become a big problem. ”

At the 784 meeting two years ago, it was decided that the structure of the domestic tank diesel engine in the future was decided, and the Coal Provincial Diesel Engine Plant intended to continue to improve the power, and the engine design institute decided to map and copy the German diesel engine, but what about its own side? We are following the path of improving the existing engine structure.

Although the existing engine is compact, as the power increases, the heat dissipation problem of the engine becomes more and more obvious due to the small core distance of the cylinder.

Now, the engine in front of you, increased to 780 horsepower, the need for heat dissipation is even greater, in the cold zone of the Soviet Union, maybe not a big problem, but in the hot environment here, the engine overheating is almost a certainty.

In order to confront their own side, they also squeezed the power of the engine vigorously, and finally the engine picked on, which is obvious.

"Yes, the potential of this engine has come to an end, and the route of our self-developed engine is definitely correct." On the side, Zhang Xiangqian also said.

"Hey, look here!" After hanging down, Wang Erzhu went up and removed the air filter, and then, when he took out the filter element of the air filter, it was all blocked by sand and dust!

"Oh, that's bad!"

When the technical experts of the eastern countries helped them overhaul, Ali and the others were of course going to help on the side, after all, they were the masters, and now, looking at the air filter, Ali was also embarrassed: "We have obviously blown it before we set off." ”

The engine cylinder is caused by many reasons, among which the engine overheating is the main reason, but the air filter element in front of you is also another inducement, because too much sand and dust is inhaled, the filter element cannot be filtered, so that the sand and dust enter the engine, cylinder liners, pistons, are worn.

"This batch of tanks was not originally prepared for the desert area, and they rushed to the desert, and the original air filter element must be insufficient, so it must be increased, replaced with a special desert filter element, and daily routine maintenance and continuous inspection to ensure the integrity of the equipment." Qin Zhenhua said on the side.

After all, the T-72 is a good thing, however, it is definitely not suitable for equipment here, unless it is improved!

Having said this, everyone was attracted by the sound of cars outside, several high-end cars, drove over, and at the same time, the number of sentries who seemed to be standing guard on the side of the road also suddenly increased, which made people suspicious.

It's probably a big shot, right?

By the time the car stopped, Khataf, Ibrahim, and even, and... The one in a military uniform, a beret, and a mustache is not...

The people around him all surrounded him and came to this side, and at this time, he was in a good mood.

"Your Excellency, this is Qin Zhenhua, don't look at him young, but, the technology is quite superb, the 69 tanks they sent over, in yesterday's comparison, our T-72 tanks were completely compared." Hataf said respectfully, looking at the mustache.

The mustache walked to Qin Zhenhua's side, his eyes were kind: "Young man, your competition yesterday brought us a lot of shock, so we plan to come over today to have a look." ”

"Your Excellency, I am glad that our tanks have won your favor." Qin Zhenhua is neither humble nor arrogant: "Yesterday's competition, we also had a fluke component, in the eyes of ordinary people, our T-55 similar tank, certainly can not be compared with the T-72, but, in fact, we won, among them, the biggest problem is that we have made special improvements according to the needs of customers, and the interests of customers are supreme, which is our purpose, you see here." ”

As he spoke, he instructed Wang Erzhu to take the air filter and shook it with his hand, and the sand and dust kept falling inside.

"This kind of device, in the European climate, can be used for at least a week without problems, but in the desert, half an hour out, it has been blocked, after that, it will have a bad impact on the engine." Qin Zhenhua said: "If you want to use it in the desert, the air filter must be at least three times the volume of the previous one to meet the needs of an operation. ”

A spare filter element of the 69 tank was sent over, Qin Zhenhua carefully compared it, and sure enough, at a glance, the filter element of the 69 tank was much larger in size, and in order to be stuffed into the engine compartment of the 69 tank, it was specially improved.

Now, which is better, clear.

The T-72 is a good thing, but if it is not specifically improved for desert climates, it will be greatly reduced!

The mustache couldn't help but nod his head: "That's right, it makes sense." ”

Translator Zhang Donglin, at this time, beads of sweat appeared on his forehead and the bridge of his nose, and he felt a heavy pressure.

"So, is there a way to change?" The other party asked.

"Of course there is, it's just that this is not our product after all, so it's inconvenient for us to start." Qin Zhenhua said: "Let's move on to the problem of armor-piercing shells. ”
