Chapter 471 A good opportunity to splash dirty water
"Overall, it is similar to our B2 series engine, so it is not difficult to overhaul."
Wu Ruihua is proficient in engines. Now, the engine has been hung out and everyone has begun to study.
In order to ensure that the test of the 69 tank can be carried out smoothly, Qin Zhenhua brought over elite soldiers and the tests in recent days have confirmed that the 69 tanks on the side have good performance and good adaptability in desert areas, so they
These technicians only need to conduct routine inspections and maintenance every day, and they will have enough time to overhaul the engine for them.
At the same time, everyone is also very interested in studying this engine.
After researching it, you can find that it is almost the same as your own engine.
Soviet tank engines were inherited from the T-34. This structure has not changed much for decades, and its power has been constantly improving.
Moreover, the path I took was almost the same as my own. By increasing the fuel supply, the power was increased from 520 horsepower to 580 horsepower, and then, through supercharge, the power was increased to more than 700 horsepower.
However, the domestic method of turbocharged increased the power to 730 horsepower, while the Soviets used mechanical supercharged increased 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 canceled the eighth main bearing of the original engine crankshaft, so that the length of the engine is basically the same as the original engine. The structure is compact and it does a good job." Wu Ruihua said: "But it is precisely because of this,
The original structure is adopted, so heat dissipation has become a big problem."
At the 784 meeting two years ago, the structure of the future tank diesel engine in China was decided. The coal-provincial diesel engine factory planned to continue to increase power. The engine design decided to survey and map the German diesel engine, but what about it? It is going to improve the existing engines.
Structure of the road.
Although the existing engines are compact in structure, as the power increases, the engine's heat dissipation problem will become more and more obvious because the cylinder center distance is too small.
Now, the engine in front of me has increased to 780 horsepower, and the need for heat dissipation is even greater. In the cold areas of the Soviet Union, there may be no big problem, but in the hot environment here, the engine overheating is almost a foregone conclusion.
In order to fight against our side, they kept squeezing the power of the engine, and finally the engine was dismissed, which was obvious.
"Yes, the potential of this engine has come to an end. The route of our self-developed engine is definitely correct." Zhang Xiangqian also said on the side.
"Hey, look here!" After hanging it, Wang Erzhu went up and removed the air filter. Then, when he took out the filter element of the air filter, it was already blocked by sand and dust!
"Oh, that's awful!"
When the technical experts from the Eastern power helped them overhaul, Ali and others of course had to help. After all, they were the masters. Now, looking at the air filter, Ali looked embarrassed: "We were obviously before we set off
It has been blown."
The engine cylinder is caused by many reasons, among which the engine overheating is the main reason, but the air filter in front of us is also another cause, because too much sand and dust are sucked in, the filter element cannot filter, allowing sand and dust into the engine.
The inside, cylinder liner, and piston are all worn.
"This batch of tanks was not originally prepared for the desert area. When they started to move to the desert, the original air filter was definitely not enough. They must be increased and replaced with special desert filters, and they were routinely maintained and inspected continuously every day.
Only by ensuring the integrity of the equipment is ensured.” Qin Zhenhua said from the side.
After all, the T-72 is a good thing, but it is definitely not suitable for equipment here unless it is improved!
Speaking of this, everyone was attracted by the sound of cars outside. Several high-end cars drove over. At the same time, the number of sentries on the roadside seemed to be on guard and guarding suddenly increased, which made people suspicious.
Come here, probably a big shot, right?
When the car stopped, Hatav, Ibrahim, and even... the one wearing military uniform, beret, and a thorny beard, wasn't that...
Everyone around him surrounded him and came toward him. At this time, he was in a good mood.
"Your Excellency, this is Qin Zhenhua. Although he is young, he is very skilled. The 69 tank they sent was completely compared to our T-72 tank in a comparison yesterday." Hata
The husband said respectfully to the mustache.
The bearded man walked to Qin Zhenhua with kind eyes: "Young man, your competition yesterday brought us a lot of shock, so we are planning to come and have a look today."
"Your Excellency, I'm glad that our tanks have won your favor." Qin Zhenhua is neither humble nor arrogant: "We also had luck in yesterday's competition. In the eyes of ordinary people, our T-55 is similar to the tank.
, It is definitely not comparable to the T-72, but in fact, we won, among which, the biggest problem is that we have made special improvements to the needs of our customers. The interests of customers are our purpose, you can see here
.”
As he said that, he instructed Wang Erzhu to take the air filter over, and waved it with his hand, sand and dust inside kept falling.
"This kind of device can be used for at least one week in European climates, but in the desert, it will be blocked after half an hour of driving, and then 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 size before to meet the needs of an action. Please take a look at our side."
A spare filter element for 69 tank was sent over. Qin Zhenhua carefully compared it. Sure enough, it was obvious that the filter element of 69 tank was much larger in size. Moreover, in order to stuff it into the engine compartment of 69 tank, it was also specially carried out.
improve.
Now, which one is better, clearly.
The T-72 is a good thing, but if there is no special improvement for the desert climate, it will be greatly reduced!
The mustache couldn't help but nodded: "Yes, what he said makes sense."
Translator Zhang Donglin, now sweat beads appeared on his forehead and nose. He felt heavy pressure. This time, there must be no errors in the translation.
"So, is there a way to change?" the other party asked.
"Of course there is, but this is not our product after all, so it is not convenient for us to start." Qin Zhenhua said: "Let's continue to talk about the issue of armor-piercing bombs."
