Rebirth of the 1980s: The Military Industry Empire

"Hey, irrelevant people, stay away!" A technician standing on the flatbed truck, busy with work, took off his leather hat, wiped the sweat from his brow, and happened to see Qin Yang and the others approaching. He immediately shouted, "This tank of ours is classified equipment, pay attention to secrecy!"

Their tank was also intended to be driven off the train here and then onto a tank transporter to be driven away. So, upon arrival, the camouflage net was removed. Since this was a small station where military trains stopped, sentries were only stationed outside. There were no additional sentries on the platform. They didn't expect that there would be busybodies from another military train! Even if we're all in the military, we still have to pay attention to secrecy.

"Irrelevant people? How do you know we're irrelevant?" Qin Yang continued to walk forward briskly as he said, "Do you believe that I have a way to start that tank engine? I'm warning you, you've already tried starting it three times. If you can't start it again, you'll have to remove the battery."

There are two ways to start a tank engine: compressed air and electric start. Each has its advantages and disadvantages. Compressed air is suitable for situations where the tank is driven every day, so the air cylinder always has high-pressure air. If it's been parked for a while and the air inside has leaked out, this starting method won't work. Electric start uses the battery's power to drive the starter motor, which is a common starting method for various vehicles.

Tank engines are powerful, so the demand for batteries is also high. A fully charged battery can only meet the needs of four starts. If it's not successful, the battery will be drained. Then, you'll need to remove the battery inside, carry it out to a warm room to charge, and then carry out a spare battery.

For every tanker, this is a chore. Take the old Type 59 tank as an example, it has four batteries, each weighing 40 kilograms. Moreover, the internal space of the tank is narrow, and only one person can crawl inside to do it. Therefore, it is customary in tank units for the four members of the crew to each take one battery, so no one slacks off.

Qin Yang was walking in the direction of the wind, so he didn't have to shout loudly for the other party to hear him clearly.

At this time, hearing Qin Yang's expert words, the other busy people looked up, looking at the young Qin Yang and the people behind him. The person who had just stopped Qin Yang was unmoved: "That's right, if we still can't start it, we'll have to remove the battery. But, what ability do you have? The one installed inside our tank isn't our commonly used 12150L diesel engine!"

"I know, isn't it the 8V331?" Qin Yang said, "MTU's flagship civilian diesel engine."

The technician's mouth widened, and the cold wind blew into his mouth, making it difficult for him to speak.

"You, how do you know?"

"I can tell from the sound. Moreover, I also know where the fault lies." After Qin Yang finished speaking, he glanced at the tank again: "However, since you don't welcome me, then forget it, Brother Lin, let's go."

"Wait!" An engineer jumped down from the tank and strode towards Qin Yang: "Comrade, please wait! My name is Liu Jingye, and I am the designer of this tank. I would like to ask, can you tell what is wrong with the engine of this tank? How should we repair it?"

"Director Liu, don't listen to him. This tank engine is imported from Germany, how could there be a problem? At most, the engine is a little cold after the journey. As long as we heat it up, we will definitely be able to start it." At this moment, the technician who had been negotiating with Qin Yang took off his dirty, tattered gloves, wrapped them around a stick, and then planned to go around to the front of the tank.

Judging from his movements, this guy planned to stick this thing into the engine oil tank opening in the front, dip some diesel, and make a simple torch to heat the engine.

Qin Yang was amused by this guy: "Are you really going to use a crude method?"

"I can tell you that if you do this, this engine will be scrapped."

"Are you saying that this imported German engine cannot be heated with an open flame? This is indeed a problem…" Liu Jingye began to think, but before he could finish speaking, he was interrupted by Qin Yang.

"Of course, that's not it. If there's really no other way, the Germans would also have to heat the engine with fire. At worst, go back and change the lubricating oil. What I'm saying is that if he sticks it into the fuel tank like this, dirty things will get into the fuel tank, which will cause irreversible damage to the precision German engine."

Qin Yang's finger pointed at Wang Zhigang. The homemade torch in his hand was rustling with dust, and there might even be iron filings in it. At this time, he had come to the right front of the tank body, and the fuel tank opening was right in front of him.

"Yes, you're right! Wang Zhigang, put down your things!" Liu Jingye looked at the thing, feeling a chill in his heart, and quickly stopped Wang Zhigang's behavior, and then looked at Qin Yang: "Please, what is the reason it can't start?"

This was already the third time, and Qin Yang couldn't delay any longer. He continued to point to the front of the tank: "It's the fuel problem."

"How could it be a fuel problem." Wang Zhigang continued to disagree: "We added negative thirty diesel, which will definitely not wax in this kind of weather. This engine can't start, it's not a fuel problem!"

"If it doesn't wax, then what's the use of you heating it with fire?" Qin Yang asked rhetorically: "The purpose of heating with fire is to heat the oil pipe so that the diesel inside melts."

Gasoline engines don't encounter this problem. No matter winter or summer, just add the corresponding grade. But diesel engines don't work. Diesel will wax at low temperatures, and even the water mixed in the diesel will cause the oil pipe and filter to freeze. In winter, heating the engine, one is to heat the oil pan, and the other is to heat the oil pipe.

"Please continue." Liu Jingye listened very carefully.

"This imported engine has been using inferior fuel for a long time, which has caused the fuel injectors to become clogged and the atomization is not good. You need to disassemble and clean the fuel injectors to use it barely."

"Nonsense, what inferior fuel." Wang Zhigang said dissatisfied: "We use the best diesel! Moreover, this tank engine has never had a problem, how could the fuel injectors be clogged, and the engine has to be disassembled?"

"Our domestic oil industry is based on Soviet standards, and the sulfur content of diesel is too high. It's no problem to use it on our domestically produced tanks, because our engines are not that precise. Using it here, that is, two hundred motorized hours, running about one thousand five hundred kilometers, the fuel injectors will be almost clogged. Don't look at it being fine when you came, but now, the failure has already occurred!"

"How do you know?" Wang Zhigang was completely surprised: "Our tank has indeed run for two hundred motorized hours, one thousand five hundred and seven kilometers! Who exactly are you?"

Wang Zhigang was the technician in charge of the tank engine, and he knew these data clearly. How could the person in front of him guess so accurately?

"Me? I am Qin Yang from Factory 960."

"What? You are that military genius?" Wang Zhigang immediately changed his attitude. He jumped off the flatbed truck and walked up to Qin Yang: "Engineer Qin, I'm sorry, I offended you just now. If I had known it was you, I would never have raised any objections!"

"Then, what are you still doing standing there?"

"That's right, let's disassemble the engine immediately!"
