At this time, Hou Baowei was pinching his waist, his face was a little ugly, and when Yang Xiaotao came, he hurriedly said, "Mr. Yang, look at this, it won't take long at all, and it will be broken." ”

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

The connecting rod is an important part that connects the piston with the crankshaft, which can convert the reciprocating linear motion of the piston into the rotary motion of the crankshaft, and then use the crankshaft to give the piston a reaction force, which must bear the force of alternating bending in its work.

"This connecting rod, according to the test requirements, can't withstand too much force at all, and it has only been deformed in less than half a day."

Other workers next to him also took the opportunity to express their opinions, they can do it, but the materials are not up to standard, and the things made are not qualified.

"Mr. Yang, we need better materials, otherwise, it won't take long for the engine to be scrapped."

Listening to the questions raised by everyone, Yang Xiaotao's face was serious, this time he was negligent.

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

Unexpectedly, the materials used to make it became the most difficult problem.

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

Waving his hand to interrupt everyone's discussion, Yang Xiaotao walked to the parts produced, "This shell is too thick, right, is there any way to solve it?" ”

Xiao Guo said, "It is best to use aluminum alloy, so that the weight will be reduced and the heat dissipation will be better." ”

Yang Xiaotao shook his head slowly after hearing this, "No, aluminum alloy, it's too expensive, how can we have so much." ”

The people are silent, the country is like this, which is what they want?

"I see it that way."

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

"In this way, it also speeds up heat dissipation."

A few people in the country have no opinion.

A few people behind him quickly found the drawings and made marks.

"And there's more."

"Cylinder, this cast iron we use is not good, we have to use higher strength and wear-resistant cast iron."

Hou Baowei said seriously on the side.

"Hmm."

Yang Xiaotao nodded in agreement, after all, this is an important part of carrying various components, and it must be hard and strong enough.

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

One person spoke, and Yang Xiaotao asked people to write it down.

"And the pistons, preferably with heat-resistant materials."

As everyone pointed out the problems one by one, after Yang Xiaotao wrote them down, he asked people to go to the warehouse to allocate them, as long as there were materials, they would be used first.

Chen Gong got the news, rushed from the logistics, and after asking about the situation, some materials that were not available, immediately contacted other factories for scheduling.

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

Busy until midnight, the parts that need to be replaced are reprocessed, and everyone does not rest, in anticipation, they start to assemble.

This time, Liu Huaimin and Wang Guodong were also watching from the sidelines, that is, Dai Qinggang and others, after getting the news, they also came to check the situation.

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, and a cool breeze blew in through the open door, making many people gathered inside shiver in unison.

"Mr. Yang, it's assembled."

Hou Baowei yawned and came over to report the situation, rubbed his eyes, and there was more expectation in his eyes.

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

The engine in front of me is very large, and it looks very heavy.

Although he didn't design it himself, every design was firmly imprinted in his mind.

Yang Xiaotao took out his glasses and circled around the engine.

There is no fault prompt.

This shows that the people are designing and manufacturing the parts according to the drawings.

It's no problem to assemble it.

But Yang Xiaotao knew in his heart that the real test was ahead.

"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, picked up the rocker and began to exert power.

Tongtong~Tong~~~

A dull sound came from the engine body, and then we saw that when the diesel fuel 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 the people around saw this scene, they all excitedly clapped their hands with the people around them to celebrate.

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

Moreover, the speed at which the crankshaft runs, in his eyes, is not fast.

"Workers, let people watch here, run all morning, and stop at noon."

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

He's going back, lying on his stomach for a while.

Xiao Guo nodded, and then began to arrange people.

During this time, there can be no shortage of fuel.

Yang Xiaotao returned to the office and rested directly in front of the desk with his eyes closed.

Soon, I fell asleep.

When Lou Xiao'e, who was at work, came in, she also relaxed when she saw this scene.

She heard about it when she was downstairs, and many people stayed up here last night, including Yang Xiaotao.

"Daddy!"

"Daddy, hug me."

"My brother beat me."

"No, my sister said me first."

In his sleep, Yang Xiaotao listened to the noisy chatter around him, and instinctively wanted to slap it over, not to mention anything else, beat the Dragon Boat Festival first.

You can't get used to beating your sister.

As a result, his hand was just about to be raised, but the subconscious movement of his body hit the leg of the table, and the pain immediately made Yang Xiaotao wake up, shaking his arm and moving.

Lou Xiao'e looked at Yang Xiaotao's ugly appearance, covered her mouth and smiled.

"What are you laughing at?"

"I taught you in a dream just now, if you don't obey, you will be beaten."

Lou Xiao'e didn't believe it, got up and handed the jar over, and Yang Xiaotao picked it up and poured two sips.

"You didn't come home last night."

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

Yang Xiaotao said, raised his hand and looked at the table below, half past ten in the morning.

"I've slept for so long?"

Lou Xiao'e nodded, "I went to Secretary Liu to deliver the documents, and he was also asleep." ”

Yang Xiaotao put down the jar, came to the side of the basin, washed his face, wiped it clean, and said, "I'll go to the workshop to take a look, you take care of it here, what's the matter, I'll talk about it when I come back." ”

Lou Xiao'e nodded.

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

Walking into the door, Hou Guowei was communicating with Liu Daming and a few others.

Liu Daming worked several shifts yesterday, and he didn't know the situation clearly, and he only learned about it when he came this morning.

"Mr. Yang."

Yang Xiaotao stepped forward, said hello to Liu Daming, then looked at the engine that was still running, took out his glasses and put them on, and checked them carefully.

In the morning, the engine was checked and there was no problem, and now, after the fault scanning, three red dots appeared in Yang Xiaotao's field of vision.

In other words, it has only been running for less than six hours, and this engine has a problem?

Such a machine, let alone for armored vehicles, even if he was asked to produce it, he would not dare.

"Stop!"

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

Liu Daming glanced at each other, quickly stepped forward and turned off the accelerator, and the engine gradually stopped.

"Ready to be demolished."

Yang Xiaotao said again, and everyone looked at each other.

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

Drain the water, drain the oil, disassemble the tool to find it, and do it at any time.

Ten minutes later, when it was ready, Yang Xiaotao disassembled it himself.

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

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

At noon, all the parts that make up the engine were disassembled by Yang Xiaotao, and a group of people in the distance looked at the parts spread out in front of them, and while sighing, they also focused on the parts specially picked out by Yang Xiaotao.

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

"There are problems in these places."

Saying that, put the parts in front, one of the pistons, one of the cylinder liners, and one of the bottom caps of the fuel tank.

Liu Daming stepped forward and looked at it carefully, but the naked eye did not see the problem.

He asked people to find tools and prepare for measurements.

Since Yang Xiaotao found it out, it is more or less problematic.

"This piston is a little deformed."

Liu Daming inspected it and saw that the piston was a little different from the data at the time of manufacturing.

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

What's more, a copy will also be spot-checked and measured before assembly.

Apparently, the piston was working and there was a problem.

As Liu Daming's words fell, Xiao Guo also shouted, "There are not many cylinder liners in this one." ”

"Me too, something is wrong with this lid."

After the three of them finished speaking, they looked at Yang Xiaotao at the same time.

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

This is a small problem that cannot be seen with the naked eye, and a small problem that can only be found with the help of tool measurement.

Unexpectedly, Yang Xiaotao found it out at random.

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

As soon as the thug tries it, he knows right from wrong.

"Yes, these three parts, the material is still not good enough."

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

Liu Huaimin walked up to him, glanced at the existing materials, and then shook his head and smiled bitterly, now these materials are already good, if

"We don't have a machinery factory, so we can only ask our superiors to help."

"Well, I'll call Huang Lao and ask them if they have a solution."

"Good!"

The two left the workshop and ran to the office.

After a while, Yang Xiaotao dialed a phone, and soon Huang Lao's voice came.

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

He knows the situation of the machinery factory, the resources and materials in the warehouse, to put it mildly, can be found in the warehouse of the machinery factory.

"What do you need?"

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

Huang Lao rubbed his temples when he heard this, "In this way, I'll ask someone first, and I'll call you back later." ”

"Okay, excuse me, chief."

Hung up the phone, Yang Xiaotao waited on the side.

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

Bell bell bell

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

"Yang Xiaotao?"

Listening to the voice, Yang Xiaotao immediately knew who it was, Zhang Lao of the Third Machine Department.

"Hello, Mr. Zhang."

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

Zhang Lao's voice on the phone was unhurried, "The eight-cylinder diesel engine you got is really unexpected." ”

"We have some aluminum alloys here, and we don't have many high-temperature resistant materials you want, and they were brought from the alliance last time."

Zhang Lao said, and Yang Xiaotao was grateful for it.

"Thank you, chief, we use a lot, you see."

"I'll send you some in a moment, it's more, it's gone."

"Okay, thank you, Chief."

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

At half past one in the afternoon, a truck entered the machine shop through the gate and came to the outside of the workshop.

The middle-aged man in the car was Director Zheng.

"Uncle Zheng, why are you here?"

Director Zheng smiled with emotion on his face.

Their third engine department was busy for more than half a year, and the four-cylinder diesel engine was not developed.

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

"I heard that you made an engine, so don't you take the opportunity to learn and learn."

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 of the security section, and everyone began a new round of manufacturing.

"This is what is resistant to high temperatures?"

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

Director Zheng smiled on the side, "This is." ”

"The specific composition of the copper alloy obtained from the alliance is not clear, but it is an important resource that we use to make aerospace equipment."

"This time, I heard that you are in urgent need, Zhang Lao also gritted his teeth and squeezed out such a little, to be honest, even if you have money now, you can't buy it, no matter how much, there is no more."

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

"I'm going to go, it can't be true."
