Seeing Zhao Guoyang's eyes fall on the engine, Liang Hongjun hurriedly beckoned to the few technicians behind him, signaling them to go over and listen to the instructions.
Looking at the few people who came up, Zhao Guoyang nodded to them and asked them to help disassemble the engine's valve device, bar head, cylinder block and piston ring assembly and other components.
After dismantling it, Zhao Guoyang carefully inspected them one by one, and there was still no problem, presumably without waiting for himself to come, the people in their factory should have already checked it.
After this inspection, Zhao Guoyang already had a rough idea in his heart.
He has some estimates on his side, but the people of the Siyang Group don't know.
Some technicians and test drivers who were watching from a distance behind whispered: "Ergou, you said that this young man is not good, it is quite smooth to call people, but these parts, haven't we also checked them?"
"It's hard to say, it's hard to say," the person called "Ergou" shook his head and said.
"We Mr.
Liang, you don't know that he has a technical background, and his level is higher than that of Minister Wang.
Where do you think you can be sent to those who can be looked at by him?"
"Hey, you're right," a few people next to him nodded in agreement when they heard this.
Just when these people were talking, Zhao Guoyang had already instructed a technician next to him to take some kerosene.
Then, he used the kerosene leakage method to check the tightness of the intake and exhaust valves, and found no signs of kerosene seepage around the intake and exhaust valves, which showed that this part itself was not leaking.
However, the circle around the intake valve seat on the combustion chamber of the cylinder head left a semi-circular trace of oil.
Seeing this scene, Zhao Guoyang was already 100% sure.
There is no doubt that there is only one possibility of this happening, and that is the tightness 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 toolbox next to him and gently tapped the valve seat insert.
Not surprisingly, the valve seat fell off with ease.
Zhao Guoyang let out a sigh of relief, turned his head and smiled at Liang Hongjun and Wang Hongxi: "Mr.
Liang, Minister Wang, count me lucky to find the problem." ” "Ah, this is where I found it" Liang Hongjun and Wang Hongxi were surprised and delighted when they heard this.
The two of them didn't care about anything else, and hurriedly walked over side by side, looking at Zhao Guoyang with hope and said, "Guoyang, what is the situation, is the problem with the engine?"
Zhao Guoyang took off his gloves, touched his chin and said: "Well, it can't be said that it is a problem with the engine, but between the valve seat and the cylinder head, when processing and manufacturing, the coordination is wrong." ” Seeing the puzzled look of everyone, Zhao Guoyang explained: "Under normal circumstances, between the intake valve seat and the cylinder head, it should be an interference fit when processing, and after pressing it, it basically can't fall off." ” "But Mr.
Liang and Minister Wang, you have also seen that the connection between the valve seat and the cylinder head of this engine is not strong, and I knocked it off with an iron rod."
This shows that the fit between the intake valve seat and the cylinder head does not meet the requirements of interference fit, and there should be a problem during processing, so that the air leakage between the valve seat insert and the combustion chamber is inevitable.
As soon as the cylinder pressure drops, the engine is difficult to start and the acceleration is weak, which is a matter of course. ” After Zhao Guoyang's in-depth explanation, Liang Hongjun and Wang Hongxi glanced at each other and nodded vigorously.
The two of them are the two leaders of the technical quality department, and they naturally know a lot about technology.
In their opinion, Zhao Guoyang's explanation is undoubtedly reasonable, and it is also a point that everyone missed before.
Xue Ming, the director of the workshop, was not proficient in technology, and after listening to Zhao Guoyang's explanation, he asked directly: "That, Section Chief Zhao, the problem has been found, is there a solution?"
Perhaps feeling that his attitude was a bit blunt, Xue Ming followed and said with a little anxiety: "Section Chief Zhao, the reprocessing of the valve seat and cylinder head will take time, I'm afraid I won't be able to catch up with tomorrow's delivery."
Zhao Guoyang grinned when he heard this: "Director Xue, it is not difficult to solve this problem, and there is no need to reprocess the cylinder head and intake valve seat.
The problem is solved by removing these intake valve seats by heating them and replacing them with new, appropriately sized ones. ” "Intake valve seats, there should be a lot of raw ones in your warehouse.
I don't think it will be difficult for you to change it according to the size I said. ” "Ah, is it really just like this, that's great," Xue Ming applauded excitedly when he heard this.
In fact, Zhao Guoyang could more or less guess the reason why this guy was in a hurry.
Needless to say, the processing of the intake valve seat and cylinder head size must be in their workshop, and now that there is a problem, of course he wants to make up for the mistakes he made in production.
Zhao Guoyang can think of this, and of course Liang Hongjun and Wang Hongxi can also think of it.
Looking at Xue Mingwei's submissive appearance, Liang Hongjun kept a calm face, couldn't help but didn't reprimand him on the spot, but said lightly: "Director Xue, you understand the situation that Section Chief Zhao just said, right?"
"I understand, I understand," Xue Ming agreed, and looked at Zhao Guoyang and said, "Thank you so much for your help this time, Section Chief Zhao."
Thank you, thank you" "Well, it's good to understand.
Next, it's up to you to make the improvements.
Remember, before the shipment is made at 10 o'clock tomorrow morning, it is important to complete all the rectifications of this batch of goods. ” "Yes, yes, Mr.
Liang, don't worry, wrap it up on me," Xue Ming nodded and said.
Seeing that things were solved, everyone breathed a sigh of relief.
Although the problem finally came out of the workshop, Wang Hongxi did not immediately leave the stall, but took the people from the technical department to continue to help dismantle the problem vehicles in the workshop.
Seeing Wang Hongxi sweating profusely and taking the lead in work, Liang Hongjun nodded secretly.
He turned his head and glanced at Zhao Guoyang, made a gesture of invitation, and said with a smile: "Guoyang, it's really all up to you today."

If you hadn't arrived in time, there might be no time when the problem would have been discovered. ” "yes.
Although Lao Wang is serious, he is still a little lacking in ability.
Zhang Zhongxiang next to him said intentionally or unintentionally.
Hearing this, Liang Hongjun's brows furrowed slightly, but he didn't say anything.
He knows a little about some of the contradictions between Zhang Zhongxiang and Wang Hongxi, and in the final analysis, it is still a matter of balance in his heart.
In the past, Wang Hongxi was very respectful to Zhang Zhongxiang in the position of deputy minister of the Ministry of Technology and Quality.
But now that he has become a regular, whether it is for the right to speak in the technical quality department or for personal face, sometimes when facing Zhang Zhongxiang, he is not very humble.
This is naturally a little uncomfortable for Zhang Zhongxiang, and it is understandable that he Wang Hongxi with two thorns in front of him from time to time.
Of course, after being in the high position of vice president, Liang Hongjun has also taken a very light look at the following intrigues.
As long as Zhang Zhongxiang and Wang Hongxi don't get too angry, he won't say anything.
Out of the door of the workshop, seeing the starry sky and the night was thick, Zhang Zhongxiang said hello to Liang Hongjun and Zhao Guoyang, and went back first.
After Zhang Zhongxiang left, Liang Hongjun patted Zhao Guoyang on the shoulder and said: "Guoyang, let's go to the canteen for some supper first, you have just arrived here, and I want you to be busy with the affairs of our factory until so late, I really don't want to go."
Zhao Guoyang hurriedly waved his hand and said: "Mr.
Liang, don't be polite with me, I really want to thank you, and I thank you first for sending a few more cars to our factory." ” What Zhao Guoyang said, naturally, was at the end of last year, Siyang Group provided a batch of special motorcycles to the following supporting factories.
While talking and laughing, the two had already walked to the cafeteria, and after sitting down, a waiter immediately brought desserts and snacks.
While eating supper, Zhao Guoyang mentioned the purpose of his trip.
When he heard Zhao Guoyang say that their factory wanted to buy a batch of Yamaha engines, Liang Hongjun basically knew it in his heart.
He took a sip slowly, then looked at Zhao Guoyang and said, "Guoyang, tell me the truth, your Hongda Machinery Factory, are you also ready to get on the motorcycle?"
In fact, even if Liang Hongjun didn't ask, Zhao Guoyang planned to say it.
In his opinion, the production of motorcycles by Hongda Machinery Factory must be impossible to conceal for three reasons.
First of all, this project is to be reported to the above, Siyang Group is originally a large national state-owned enterprise, the news is very well-informed, suddenly a competitor appeared, people will not be able to inquire about the origin Secondly, Zhao Guoyang never felt that between peers, it must be a competitor.
In his opinion, with the current demand of the Huaxia 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.
Between Zhao Guoyang and Liang Hongjun, after getting along several times, they can be regarded as friends.
As a friend, it's good to compete openly, and engaging in those unsightly small means is not what Zhao Guoyang likes.
After Liang Hongjun asked this, Zhao Guoyang's expression changed and he said calmly: "That's right, Mr.
Liang."
Our Hongda Machinery Factory has just obtained a small state-owned enterprise transformation grant from the Ministry of Finance a few years ago, and I discussed with several leaders of our factory and decided to try to engage in motorcycles. ” "However, Mr.
Liang, don't worry, we are engaged in scooters, and there should be no conflict in business competition with your factory."
Zhao Guoyang followed and said.
"Hehe, not now, it doesn't mean that there will be no wow, especially Hongda Machinery Factory, with you as a tiger general, the future can be expected," Liang Hongjun sighed.
For Liang Hongjun's disguised praise, Zhao Guoyang just smiled and didn't say anything.
The communication between smart people like him and Liang Hongjun is normal and normal, but it is easy to be disgusted by engaging in some empty brains
