Chapter 1196 Finding the Problem

At this time, Hou Baobao was pinching his waist with an ugly look on his face. When Yang Xiaotao arrived, he quickly said, "Mr. Yang, look at this, it won't take long before it breaks down."

Handed over a somewhat twisted connecting rod, Yang Xiaotao frowned and looked at it.

The connecting rod is an important component that connects the piston to the crankshaft. It can convert the reciprocating linear motion of the piston into the rotational motion of the crankshaft, and then use the crankshaft to give reaction force to the piston. It must withstand alternating bending forces during work.

"This connecting rod, according to the test requirements, could not withstand too much force. It took less than half a day to deform."

Other workers nearby also took the opportunity to express their opinions. They could do it, but the materials were not up to standard and the products they made were substandard.

"Mr. Yang, we need better materials, otherwise, the engine will be useless in a short time."

Listening to the questions raised by everyone, Yang Xiaotao looked serious. This time he was negligent.

In his opinion, there is no problem with the rewards given by the system.

Unexpectedly, the materials for production have become the most difficult problem.

"Let's talk about it one by one."

Waving his hand to interrupt everyone's discussion, Yang Xiaotao walked to the production parts and said, "This casing is too thick, isn't it? Is there any way to solve it?"

Pang Guo said, "It's best to use aluminum alloy, which will reduce weight and have better heat dissipation."

Yang Xiaotao shook his head slowly after hearing this, "No, aluminum alloy is too expensive. We don't have that much."

Everyone was silent. The national conditions are like this. How can they just do whatever they want?

"I see it this way."

Yang Xiaotao glanced at several modules of the main body of the engine, "The main body parts are still made of cast iron, and other small parts are made of aluminum alloy."

"In this way, heat dissipation can also be accelerated."

The people in Pangguo had no objection.

Several people behind him quickly found the drawings and made marks.

"anything else."

"Cylinder, the cast iron we use is not good for this. We need cast iron with higher strength and wear resistance."

Hou Baobao said seriously from the side.

"Um."

Yang Xiaotao nodded in agreement. After all, this is an important part that carries various components, and it must be hard and strong enough.

"There are also connecting rods and crankshafts. We are using ordinary steel now. It is best to replace them with high-quality alloy steel."

When someone spoke, Yang Xiaotao asked someone to write it down.

"And the piston, it's best to use heat-resistant material."

As everyone pointed out the problems one by one, Yang Xiaotao took note of them and asked people to go to the warehouse to prepare them. As long as there were materials, they would be used first.

Chen Gong got the news and came from the logistics department. After asking about the situation, he immediately contacted other factories for dispatch of some materials that were not available.

When the materials arrived, Yang Xiaotao worked with everyone to replace some parts.

Working until midnight, the parts that needed to be replaced were reprocessed, and everyone started assembling in anticipation without rest.

This time, Liu Huaimin and Wang Guodong were also watching, and even Dai Qinggang and others came to check on the situation after getting the news.

The success or failure of the engine is related to their future design direction.

When the sky lit up again, it was deserted outside the factory. A cool breeze blew in from the open door, making many people gathered inside shiver.

"Mr. Yang, it's assembled."

Bao Bao Hou yawned and came over to report the situation. He rubbed his eyes and his eyes were full of expectation.

Yang Xiaotao also rubbed his eyes, held a kettle in his hand, took a sip of warm water, and finally walked to the assembled engine.

The engine in front of me is huge and looks very heavy.

Although this was not designed by himself, every design is firmly imprinted in his mind.

Yang Xiaotao took out his glasses and circled the engine.

There is no fault message.

This shows that everyone designed and manufactured the parts according to the drawings.

There is no problem in assembling it.

But Yang Xiaotao knew in his heart that the real test would come later.

"Come on, add water, give it a try."

Soon, someone found diesel and water, and after adding it to the engine, a worker stepped forward, swung the rocker and started to exert force.

Tongtong~tong~~~

A dull sound came from the engine body, and then I saw that when the diesel entered the cylinder, a row of cylinders started one by one, and then completed the work in the cylinder, driving the connecting rod and crankshaft.

When people around saw this scene, they all excitedly clapped their hands to celebrate.

But Yang Xiaotao frowned slightly, because the sound of the engine was a little abnormal.

Moreover, the speed of the crankshaft was not fast in his eyes.

"Pang workers, let people watch here. It will run all morning and stop at noon."

Yang Xiaotao said a few words, turned around and walked to the office.

He wants to go back and lie down for a while.

Pang Guo nodded and then began to arrange people.

During this time, there cannot be a shortage of fuel.

When Yang Xiaotao returned to the office, he lay down in front of his desk and closed his eyes to rest.

Soon, he fell asleep.

When Lou Xiaoe, who was at work, came in, she slowed down when she saw this scene.

She heard about it when she was downstairs. Many people stayed here all night last night, including Yang Xiaotao.

"dad!"

"Dad, give me a hug."

"Brother hit me."

"No, it was my sister who told me first."

In his sleep, Yang Xiaotao listened to the noise around him, and instinctively wanted to slap Duan Wu in the face, among other things.

You can't take it for granted that you beat your sister.

As a result, just as he was about to raise his hand, his body subconsciously bumped into the table leg. The pain immediately woke Yang Xiaotao up, and he swung his arms and moved.

Lou Xiaoe looked at Yang Xiaotao's embarrassing appearance and covered her mouth and laughed.

"What are you laughing at?"

"I was just teaching you a lesson in my dream. If you don't obey, you will be beaten."

Lou Xiaoe didn't believe it. She stood up and handed the jar to Yang Xiaotao. Yang Xiaotao took it and drank two gulps.

"You didn't go home last night."

"Nonsense. By the way, what time is it?"

Yang Xiaotao said, raised his hand and looked at the watch. It was half past ten in the morning.

"I slept so long?"

Lou Xiaoe nodded, "I went to deliver documents to Secretary Liu, and he was also asleep."

Yang Xiaotao put down the jar, came to the washbasin next to him, washed his face, wiped it clean and said, "I'll go to the workshop to take a look. You can take care of it here. If there is anything, I will come back to talk."

Lou Xiaoe nodded.

When Yang Xiaotao came to the door of the third workshop, he heard the sound coming from inside and frowned.

Walking into the gate, Pang Guohou, the guard, was communicating with Liu Daming and others.

Yesterday, Liu Daming and others were on shift and didn't know the situation. He only found out when he came this morning.

"Mr. Yang."

Yang Xiaotao came forward and greeted Liu Daming and others, then looked at the engine that was still running, took out his glasses and put them on, and carefully checked it.

The engine that had no problems in the morning inspection, now, after the fault scan, three red dots appeared in Yang Xiaotao's field of vision.

In other words, this engine has been running for less than six hours, and it has gone wrong?

Such a machine, let alone using it for armored vehicles, he dare not even produce it.

"Stop!"

Yang Xiaotao took off his glasses and said to the people around him.

Liu Daming and others looked at each other, quickly stepped forward to turn off the throttle, and the engine gradually stopped.

"Prepare to dismantle."

Yang Xiaotao said another sentence, and everyone looked at each other.

However, Yang Xiaotao's face was serious, and his words were even more unquestionable, so everyone had to obey the arrangement.

Drain the water, drain the oil, find the disassembly tools, and start at any time.

Ten minutes later, everything was ready, and Yang Xiaotao started to disassemble it himself.

Not long after, Liu Huaimin and others rushed over, looking at the pile of parts on the ground, they were all surprised.

Seeing Yang Xiaotao busy, everyone could only hold their breath and wait for the final result.

At noon, all the parts that made up the engine were disassembled by Yang Xiaotao. A group of people in the distance looked at the parts spread out in front of them, and they were moved, and they focused their eyes on the parts that Yang Xiaotao had specially picked out.

After all the parts were disassembled, Yang Xiaotao stood up, took off his gloves, and picked up three parts on the side.

"There are problems in these places."

He said and put the parts in front, one of which was a piston, one was a cylinder liner, and the other was the bottom cover of the fuel tank.

Pang Guo, Liu Daming and others came forward and looked at it carefully, but they didn't see any problems with their naked eyes.

Pang Guo asked people to find tools and prepare to measure.

Since it was found by Yang Xiaotao, there must be problems more or less.

"This piston is a little deformed."

Liu Daming checked it and found that the data of the piston was slightly different from that when it was manufactured.

With the current technical literacy of workers, there is no such a big difference.

Besides, a sample will be randomly checked and measured before assembly.

Obviously, there was a problem with this piston when it was working.

As Liu Daming's voice fell, Pang Guo also shouted, "This cylinder sleeve is not much."

"Me too, this cover is wrong."

The three of them said, and then looked at Yang Xiaotao at the same time.

Not only them, but a group of people around looked at Yang Xiaotao.

This little problem, a small problem that cannot be seen by the naked eye, a small problem that can only be found with the help of tools.

Surprisingly, it was found by Yang Xiaotao casually.

This, this is not only a skill, but also a feeling of extraordinary means.

A try to know right and wrong.

"Yes, the materials for these three parts are still not good enough."

Yang Xiaotao found the problem and said seriously, "So, these three parts need better materials."

Liu Huaimin walked up to him, took a look at the existing materials, then shook his head and smiled bitterly. These materials are already good now. If

"Our machinery factory doesn't have them, we can only ask our superiors for help."

"Well, I'll call Mr. Huang and ask if they have any solutions."

"Okay!"

The two left the workshop and ran to the office.

After a while, Yang Xiaotao called the First Ministry of Machinery and soon heard Mr. Huang's voice.

After explaining the situation on the phone, Mr. Huang frowned.

He knew the situation of the machinery factory. To be frank, the resources and materials in the warehouse of the First Ministry of Machinery can be found in the warehouse of the machinery factory.

"What do you need?"

"Commander, we need materials that are wear-resistant, high-pressure-resistant and hard enough, preferably aluminum alloys."

After hearing this, Mr. Huang rubbed his temples, "Well, I'll ask someone first and call you back later."

"Okay, thank you, Commander."

After hanging up the phone, Yang Xiaotao waited on the side.

Lou Xiao'e came back from the cafeteria and brought a lunch box for Yang Xiaotao, and then ate in the office.

Ring, ring, ring

About ten minutes later, the phone rang, but it was not Mr. Huang's voice.

"Yang Xiaotao?"

Hearing the voice, Yang Xiaotao immediately knew who it was, Mr. Zhang from the Third Machine Department.

"Hello, Mr. Zhang."

"It's okay. Xiao Huang called me just now and asked."

Mr. Zhang's voice on the phone was unhurried and unhurried, "The eight-cylinder diesel engine you built is really unexpected."

"We have some aluminum alloy here. We don't have much of the high-temperature resistant material you want. We got it from the alliance last time."

Mr. Zhang said, Yang Xiaotao was very grateful after hearing this.

"Chief, thank you, we have used a lot, you see."

"I'll send you some later. If there's too much, it's gone."

"Okay, thank you, chief."

After hanging up the phone, Yang Xiaotao put down his lunch box and ran to the workshop again.

At half past one in the afternoon, a truck entered the machinery factory through the gate and came outside the workshop.

The middle-aged man who got off the car was none other than Director Zheng.

"Uncle Zheng, why are you here?"

Director Zheng smiled with emotion on his face.

Their third engine department has been busy for more than half a year, but the four-cylinder diesel engine has not yet been developed.

But in the blink of an eye, this guy came up with an eight-cylinder diesel engine, which was a slap in the face.

"I heard that you have made an engine. Why don't you take this opportunity to learn from it?"

Director Zheng said what was in his heart, but Yang Xiaotao took it as a joke.

Soon, the materials on the car were moved into the workshop by the comrades from the security department, and everyone started a new round of manufacturing.

"Is this a high-temperature resistant material?"

Looking at the board, which was only one square meter in size, Yang Xiaotao was very curious and felt that the material looked familiar.

Director Zheng smiled on the side, "That's it."

"The specific composition of the copper alloy obtained from the alliance is unclear, but it is an important resource we use to manufacture aerospace equipment."

"This time I heard that you are in urgent need, so Mr. Zhang gritted his teeth and squeezed out this little. To be honest, even if you have money now, you can't buy it. No matter how much you have, it will be gone."

Director Zheng said seriously, while Yang Xiaotao stared at the orange-yellow copper alloy and suddenly thought of it in his mind.

"I'll leave it alone, it can't be true."
