Seeing Zhao Guoyang's eyes falling on the engine, Liang Hongjun quickly waved to the technicians behind him and signaled them to come over and wait for instructions.

Looking at the few people coming up, Zhao Guoyang nodded to them and asked them to help disassemble the engine's air distribution device, bar head, cylinder block and piston ring assembly and other components.

After dismantling it, Zhao Guoyang carefully checked it one by one, and there was still no problem. I guess everyone in their factory should have checked it before he could come.

After this examination, Zhao Guoyang was already at a loss.

He has some estimates here, but the people from Siyang Group don’t know.

Some technicians and test runners who were watching from afar whispered: "Ergou, do you think this young man is OK? It's quite smooth to call people, but have we checked all these parts?"

"It's hard to say, it's hard to say!" The man named "Ergou" shook his head and said.

"You don't know yet, Mr. Liang? He is a technical background and has a higher level than Minister Wang. How bad do you think the person who can be attracted to him?"

"Hey, you're right!" The few people next to him nodded and agreed after hearing this.

Just as these people were talking, Zhao Guoyang had already instructed a technician around him to take some kerosene over.

Then, he used the kerosene leakage method to check the sealing of the inlet and exhaust valves. There were no signs of kerosene seeping out around the inlet and exhaust valves, which means that there is no leakage in this part.

However, a semicircular oil stain mark was left in the circle around the intake valve seat on the combustion chamber of the cylinder head.

Seeing this scene, Zhao Guoyang was already 100% sure.

There is no doubt that there is only one possibility for this situation, that is, the sealing between the valve seat and the cylinder head, which must be a problem.

After finding the problem, Zhao Guoyang picked up an iron rod from the tool box next to him and gently tapped the valve seat.

As expected, the valve seat fell off easily.

Zhao Guoyang let out a long sigh and turned to Liang Hongjun. Wang Hong smiled happily and said, "Mr. Liang, Minister Wang, I'm lucky and found the problem."

"Ah! You're found this!" Liang Hongjun and Wang Hongxi were both surprised and happy when he heard this.

The two of them didn't care about anything else, and quickly walked over side by side, looking at Zhao Guoyang with hope and said, "Guoyang, what's going on? Is the problem in the engine?"

Zhao Guoyang took off his gloves, touched his chin and said, "Well, it cannot be said that it is an engine problem. It's just that the cooperation between the intake valve seat and the cylinder head was made wrong during processing and manufacturing."

Seeing everyone's puzzled appearance, Zhao Guoyang explained: "Under normal circumstances, the processing between the intake valve seat and the cylinder head should be an interference coordination. After pressing it, it basically cannot fall off."

"But Mr. Liang and Minister Wang, you have also seen that the connection between the intake valve seat and the cylinder head of this engine is not firm. I knocked it lightly with an iron rod and it fell off."

"This shows that the coordination between the intake valve seat and the cylinder head does not meet the requirements of interference coordination. It should be a problem during processing. In this way, air leakage between the valve seat and the combustion chamber is inevitable. Once the cylinder pressure drops, it will be difficult to start the engine and unable to accelerate, which is natural."

After Zhao Guoyang's explanation in an easy-to-understand manner, Liang Hongjun and Wang Hongxi looked at each other and nodded vigorously.

They are two leaders in the Technical Quality Department, one after another, and one after another, so they naturally have a lot of knowledge about technology.

In their opinion, Zhao Guoyang's explanation is undoubtedly reasonable and is also a point that everyone missed before.

The workshop director Xue Ming was not proficient in technology. After listening to Zhao Guoyang's explanation, he asked directly: "Well, Section Chief Zhao, the problem has been found. Is there a solution?"

Perhaps feeling that his attitude was a little stiff, Xue Ming then said anxiously: "Secretary Zhao, it takes time to reprocess the intake valve seat and cylinder head. I am afraid that I will not be able to catch up with tomorrow's shipment!"

Zhao Guoyang grinned and said, "Director Xue, it is actually not difficult to solve this problem, and there is no need to reprocess the cylinder head and intake valve seat. As long as you use heating, take off these intake valve seats and replace them with a new intake valve seat of the right size, the problem will be solved."

"There should be a lot of unprocessed air intake valve seats in your warehouse. I will process them according to the size I mentioned and replace them. I think it should not be difficult for you."

"Ah, is it really enough to do this? That's great!" Xue Ming clapped excitedly when he heard this.

In fact, Zhao Guoyang could guess the reason why this guy was yelling in a hurry.

Needless to say, the processing of the intake valve seat and cylinder head size must be the responsibility of their workshop. Now that there is a problem, he certainly wants to make up for his mistakes and make up for the mistakes he made in his production.

Zhao Guoyang would like to think of these things, and Liang Hongjun and Wang Hongxi would certainly want them too.

Looking at Xue Ming's timid appearance, Liang Hongjun had a calm face and refused to scold him on the spot. He just said lightly: "Director Xue, you have understood everything that Section Chief Zhao just said, right?"

"I understand, I understand everything!" Xue Ming agreed and looked at Zhao Guoyang and said, "I really thank you Section Chief Zhao for your help this time. Thank you, thank you!"

"Well, it's good to understand. Next, this improvement will be left to you. Remember, before shipment at 10 o'clock tomorrow morning, be sure to complete the rectification of all this batch of goods."

"Yes, yes, yes, Mr. Liang, don't worry, it's wrapped around me!" Xue Ming nodded and said.

When everyone saw that the matter was solved, they breathed a sigh of relief.

Although the problem ultimately lies with the workshop, Wang Hongxi did not immediately leave the house, but instead led the technical department's staff to continue to help disassemble the problematic vehicles in the workshop.

Seeing Wang Hongxi sweating provokingly, Liang Hongjun nodded secretly.

He turned his head and looked at Zhao Guoyang, made an invitation gesture, and said with a smile: "Guoyang, it's all up to you today. If you didn't arrive in time, this problem might not be discovered."

"Yes. Although Lao Wang is serious in his work, he still lacks ability." Zhang Zhongxiang next to him said intentionally or unintentionally.

After hearing this, Liang Hongjun frowned slightly, but said nothing.

He knew a little about some of the contradictions between Zhang Zhongxiang and Wang Hongxi. After all, it was a question of balance in his heart.

In the past, Wang Hongxi was very respectful to Zhang Zhongxiang as the deputy director of the Technical Quality Department.

But now that he has become a regular employee, whether it is for the right to speak in the Technical Quality Department or personal face, sometimes he is not very humble when facing Zhang Zhongxiang.

This naturally made Zhang Zhongxiang feel a little uncomfortable. From time to time, he laid two thorns on Wang Hongxi in front of him, which is understandable.

Of course, after ranking at the high position of vice president, Liang Hongjun has already taken the following intrigues.

As long as Zhang Zhongxiang and Wang Hongxi don’t make a big fuss, he won’t say much.

After leaving the workshop gate, I saw the stars in the sky and the night was dark. Zhang Zhongxiang and Liang Hongjun, Zhao Guoyang greeted him and went back first.

After Zhang Zhongxiang left, Liang Hongjun patted Zhao Guoyang on the shoulder and said, "Guoyang, let's go to the cafeteria to have some midnight snacks now. You have just arrived all the way and you are going to be busy with our factory until so late. I am really sorry..."

Zhao Guoyang quickly waved his hand and said, "Mr. Liang, don't be polite to me. I really want to thank you. I would like to thank you for sending a few more cars to our factory."

What Zhao Guoyang said was naturally the matter of Siyang Group providing a batch of special motorcycles to the supporting factories at the end of last year.

While chatting and joking, the two had already walked to the cafeteria. After sitting down, a waiter immediately brought desserts and snacks.

While having a midnight snack, Zhao Guoyang roughly mentioned the purpose of his trip.

When Zhao Guoyang heard that their factory wanted to add a batch of Yamaha engines, Liang Hongjun basically knew it.

He slowly drank the water, then looked at Zhao Guoyang and said, "Guoyang, tell me the truth, are you Hongda Machinery Factory also ready to get on the motorcycle?"

In fact, even if Liang Hongjun didn't ask about this, Zhao Guoyang planned to tell it.

In his opinion, Hongda Machinery Factory's motorcycle production is definitely not hidden, and there are three reasons.

First of all, this project needs to be reported to it. Siyang Group is a large state-owned enterprise with a very well-informed information. Suddenly, a competitor appeared. Will people not be able to find out the origin?

Secondly, Zhao Guoyang never felt that peers must be competitors. In his opinion, with the current demand in the Chinese motorcycle market, it is entirely possible to achieve a win-win cooperation between Hongda Machinery Factory and Siyang Group, and there is no need to hide it.

The last reason is personal reasons. After several times of getting along with Zhao Guoyang and Liang Hongjun, they can be regarded as having friends. As friends, it is good to compete openly. Those shameful tricks are not something Zhao Guoyang likes.

After Liang Hongjun asked this, Zhao Guoyang looked calm and said calmly: "That's right, Mr. Liang. Our Hongda Machinery Factory just obtained the transformation grant from a small state-owned enterprise from the Ministry of Finance a year ago. I discussed it with several leaders of our factory and decided to try to make a motorcycle."

"However, Mr. Liang, don't worry, we are doing scooters, and there should be no conflicts in business competition with your factory." Zhao Guoyang said.

"Haha, there is no now, it does not mean there is no future! Especially with Hongda Machinery Factory, you, the tiger general, the future is promising..." Liang Hongjun sighed quite.

Zhao Guoyang just smiled and said nothing about Liang Hongjun's disguised praise.
