Fortunately, the parts that failed the engine can be found here. This way, repairing them all night long can also catch up with tomorrow's tests. However, it was a bit uncomfortable for two consecutive days.
"After the new cylinder and piston are replaced, even if the engine has been overhauled, will it take a running-in after the overhaul?" Zhang Zhong also helped, watching the shiny piston being stuffed into the cylinder, he couldn't bear it.
asked the residence.
"No need to run-in." Qin Zhenhua replied very simply: "We have introduced advanced precision grinding technology, and the engine no longer needs to run-in."
When it comes to engine running-in, many veteran drivers will talk endlessly. If the engine is not running-in, it will greatly reduce the lifespan. Run-in is to eliminate rough surfaces, achieve the best use state, etc.
In fact, with the continuous development of technology, the operation of running-in has gradually been eliminated. In the later generations, if someone still says that cars need to be running-in, it is really an old argument, and advanced technology,
It was first used on tank engines. The current tank engines have given up the step of running-in because they have been precision ground before assembly, which is enough to ensure the normal use of the engine.
In fact, for tank engines, running-in is a false proposition. The old engines in the past require overhaul in 500 hours, and only 500 hours. This is equivalent to the end of the lifespan of ordinary vehicles before the running-in period has expired.
, so, there is no need to do it.
Now, the lifespan of tank engines is increasing, but the running-in step has begun to be omitted.
Just like turbocharger, it has been criticized by countless car mechanics with decades of skills, saying that self-priming has a high lifespan, turbos are prone to breakage, etc., without knowing at all, as early as the 1970s and 1980s, advanced tank engines
It has begun to enter the era of turbocharger.
The current tank engines no longer need to be run-in.

Hearing Qin Zhenhua's words, Zhang Zhong opened his eyes wide: "No need to run-in? How is this possible?"
"What's impossible?" Qin Zhenhua said: "The goal of running-in is to make the surface smoother. We have polished it smooth enough in advance, so what else is running-in."
"Technology is constantly developing and improving, we must look at problems from a developmental perspective." Qin Zhenhua said, patting Zhang Zhong on the shoulder: "Young man, learn more about new knowledge, otherwise, you will be in front of us Qianqian,
It's hard to have a common language."
Zhang Zhong nodded quickly, saying this was to mention him.
"Hmph, he, without this pursuit, he likes to hold on to the old arguments of the past." Nie Qianqian gave Zhang Zhong a blank look.
"Why don't there be spare parts for this engine oil filter?" At this moment, Wang Erzhu shouted.
The reinstallation was carried out very quickly in the hands of skilled technicians, and now the assembly has begun. However, Wang Erzhu found that one of the parts had missed the accessories.
"Well, I just forgot about this, but the carbon deposit in the cylinder should have nothing to do with the engine oil filter. Let's use the original one." Qin Zhenhua said.
Let Lao Ba send another trip? It probably won’t work anymore. When they arrive, it’s dawn, so just use the original one. Anyway, this carbon deposit has nothing to do with the engine oil filter.
"Okay." Wang Erzhu could only nod in agreement. At this time, everyone didn't know and made another mistake.
When the sun in the east rises again, the 85-3 tank is ready to set off again. The personnel responsible for repairs were all very tired. Fortunately, today's operation can be handed over to the testers in Pakistan.
After all, if the people of Ba people want to buy tanks, they have to try it themselves. Just like buying a car in later generations, they have to test drive it.
"Please rest assured that our testers are the most professional and can definitely play the best level of the tank." Kalamat said: "Now, please ask the 85-3 tank to test first."
The tankers in Pakistan have long been familiar with the Type 85 tank. Now, they are extremely familiar with the 85 tank body. After the technicians briefly explain it, they can get started.
On the other hand, the T-80UD tank is different. This tank is the most advanced tank before the collapse of the Soviet Union. Many operations are different from the 59 and 69 tanks. Therefore, when the 85-3 tank was tested, the T-80UD tank was tested.
Next to it, a large group of technicians were explaining how to operate to testers in Pakistan.
For Ermao, this should be the busiest day.
After the test results of this day, the tanks of both sides almost tied.
That's right, it's a tie.
After all, the T-80UD tank uses a diesel engine with a capacity of 1,200 horsepower, and is powerful. Even if the test personnel are not particularly familiar with it, they can still exert a certain degree of strength. The 85-3 tank occupies the operational training.
Su's advantage, so he played the highest level in the test, so that the two sides could have a draw.
At this time, Qin Zhenhua had a vague premonition in his heart. If this continues, it will be difficult to pursue!
"So far, the main test is still maneuverability." That night, a few people gathered together and began to discuss the next countermeasures. Wang Erzhu's mind was still clear and introduced to everyone: "Next,
We will also test firepower. In this link, we still have great advantages. After all, the performance of tank guns in the Soviet era is simply not as good as our products."
Although they are all 125mm guns, the tank barrel pressure of the Eastern powers is higher and the shells are more advanced, which is the achievements made by the Eastern powers in recent years.
Now, after hearing Wang Erzhu's words, everyone nodded, and Qin Zhenhua also pointed out the problem: "However, the Soviet Union had gun-fired missiles, and Ermao also had gun-fired missiles, so they must have wanted to fire through gun-fired missiles.
Missiles are used to improve their performance.”
The Soviets were not as good as Eastern powers in conventional artillery shells, but they were awesome in artillery missiles. Now, everyone knows that they should not underestimate the enemy, and they must analyze Ermao's subsequent movements clearly.
"However, we also know that the gun-fired missiles are in Damao, so we must point them out." Qin Zhenhua said.
The shopping mall is like a battlefield. At this time, there is no need to pay attention to the gentleman style. If you should pour dirty water, you have to pour dirty water. In order to win the contract, why do you care about so much? Moreover, this is also for the sake of Pakistan. Now, the test is the smallpox.
When it comes to purchasing, I find that all kinds of parts have to be ordered from Damao. At that time, will the Pakistani country be cheated?
As good friends of Pakistan, they have the obligation to point out this serious problem.
