Chapter 4 shows his ability in one sentence
In any automobile factory, the production line shutdown is considered a major abnormality.
Whether the supplier's parts do not arrive on time, or the parts are found to be of poor quality during the assembly process, or problems are discovered when the vehicle comes off the assembly line, it may cause the line to be shut down.
Liao Chengwen has been at the Capital Automobile Manufacturing Plant for so many years, and naturally he has encountered countless line suspension problems.
So he was not particularly nervous.
"Xiao Chen, why did the production line stop?"
On the way to the line-stopped workshop, Liao Chengwen must have seized the opportunity to understand some of the process of the matter.
Otherwise, it will be troublesome if we can’t resume production even after working on site for a long time.
"There are abnormal noises and jitters in the engine. They have initially confirmed that there is no problem with the installation of the engine. The rest is not clear."
Chen Chenxing is a little transparent in the technical department. A few years after graduating from high school, in order not to go to the countryside, I worked very hard after using connections to get in. However, I really don’t have the talent in this area, and now I can’t even fully understand the drawings.
Jiang Hui followed Liao Chengwen and naturally listened to these words.
Engine noise and vibration are generally due to a few reasons.
Now it will actually stop production?
Capital Automobile Manufacturing Plant’s understanding of engine technology seems a bit superficial.
"Dong Ke, if you really can't find the reason, please ask someone from the Capital Internal Combustion Engine Factory to come over as soon as possible."
"If there is a problem with the engine, it must be their responsibility."
Just as Liao Chengwen was rushing towards the production line, Liu Darui, chief of the vehicle quality department, suggested asking the engine supplier to come over and solve the problem.
This is naturally a way to solve the problem.
However, the OEM has no way to quickly analyze the problem and needs to invite suppliers to the site to solve it. This is somewhat embarrassing.
Not to mention there is a special story between the two parties.
Therefore, Dong Jianpeng, chief of the quality department, still wants to work hard.
The meaning of finding out the problem yourself and then notifying the supplier to correct it is different.
Otherwise, what is the meaning of the existence of their quality department?
“From past experience, engine vibration and abnormal noise are either caused by improper installation, or the piston or valve is severely worn or damaged.”
"But it stands to reason that a brand new engine, piston and valve are unlikely to have any problems."
The weather in the capital in July is already very hot.
Dong Jianpeng is feeling a little nervous now, his face is covered with sweat.
"Dong Ke, why don't you take it apart and confirm?"
What Liu Darui said made Dong Jianpeng a little confused.
It’s not like they have never done anything like dismantling an engine.
But after all, he is not a professional engine technician, so he is not very confident whether he can put it back together normally after taking it apart.
It would be embarrassing if there are more problems after reinstalling.
While Dong Jianpeng was struggling, Chen Chenxing brought Liao Chengwen to the scene.
"Old Dong, how is the situation?"
Liao Chengwen's words were like the sound of nature to Dong Jianpeng.
In terms of parts problem analysis, the technical department is more professional than the quality department.
“All the vehicles that started rolling off the production line around 9 o’clock this morning were found to have obvious abnormal noise and vibration problems during the verification process at the vehicle quality department. A total of 6 vehicles were involved.”
"The reason has not been found yet. If we can't find it within half an hour, we will have to ask someone from the Capital Internal Combustion Engine Factory to come over and analyze it."
Dong Jianpeng and Liao Chengwen are from the quality department. The section chiefs, one is the chief of the technical section, they are old acquaintances. The relationship between Capital Automobile Manufacturing Plant and Capital Internal Combustion Engine Plant is a bit delicate, and everyone wants to have the right to speak.
So the relationship between the two is not the kind of relationship between Party A and Party B that everyone imagines.
Engine noise and vibration problems have also occurred in the past, and the final confirmed cause was that the engine bracket was loose or damaged.
This obviously has nothing to do with the Capital Internal Combustion Engine Factory.
But Dong Jianpeng and the others didn't know that at the time. They called him over angrily and scolded them, but they found out that they were scolding the wrong person.
After similar things happened two or three times, the attitude of the Capital Internal Combustion Engine Factory also changed.
We are all state-owned enterprises, and even the administrative levels are the same.
I definitely don’t want to be scolded by you in vain.
In this case, the relationship between the two parties will definitely not be so wonderful.
Of course, the respective factory directors may not be very clear about this kind of thing. It is mainly the people in the various departments below who care more about it.
“The occurrence of 6 cars having the same fault at one time shows that it is a batch problem.”
"If there is no problem with the engine installation, it must be the problem with the engine itself."
Liao Chengwen is also very clear about the strength of the technical department in the engine field. There is no one who specializes in this matter. .
Capital Automobile Industry Street, Capital Automobile Manufacturing Factory, Capital Internal Combustion Engine Factory, Capital Gear Factory, etc., everyone is responsible for their own part.
One is building complete vehicles, one is working on engines, and the other is researching gearboxes.
Other parts companies basically listen to the Capital Automobile Manufacturing Plant.
But for engine and gearbox manufacturers, since everyone has the same administrative level, communication is not just about giving orders directly.
"Liao Ke, I feel the same way."
"So this time I think we can directly call the people from the Capital Internal Combustion Engine Factory."
Liu Darui listened. After listening to Liao Chengwen's words, he once again emphasized his point of view.
Liao Chengwen did not answer directly, but came to the driver's seat to experience it in person, and then stared at the engine compartment for more than ten minutes.
However, although his various actions looked very professional, in fact he did not dare to draw any conclusions.
Because he actually doesn’t know much about engines.
This year, unlike later generations, many people have some understanding of the structure of the engine.
"Old Liao, the shutdown time is a bit long, why don't we just call the people from the Internal Combustion Engine Factory to come over?"
Dong Jianpeng also chose to give up at this time.
Obviously, he has seen that Liao Chengwen seems to be unable to solve this problem.
Jiang Hui, who had been silent next to him, saw that his senior brother seemed to be ready to accept the reality that he could not handle it, so he couldn't help but said: "Liao Ke, this abnormal noise and vibration sounds like the engine is missing. From the look of the engine oil, I guess there is something wrong with the oil pump.”
It’s definitely okay to call him senior in private, but in this formal situation, it’s definitely more appropriate to call him “Liao Ke”.
Although Jiang Hui just graduated from college this month and went to the Workers', Peasants and Soldiers' University, which is still looked down upon by others, he has a soul with more than 40 years of life experience and naturally knows how to deal with various situations.
“Abnormal noise caused by the oil pump?”
Liao Chengwen frowned, "Why are you sure there is something wrong with the oil pump?"
