Chapter 143 Hello! The new BJ212
“The Hummer model is destined to be a series of models in the future. The most critical thing is to develop chassis-related parts.”
“Then the powertrain cannot be As long as these two aspects are in place, the other aspects will not have much impact."
"I will come to the school next Tuesday to take a look and solve some major bottleneck parts first."
“From now on, I will find one day every week to come to school to work with everyone on the Hummer project.”
When my father-in-law comes to ask for help, Jiang Hui will definitely give him his full support.
After the Hummer is produced, it is destined to be a classic of an era. It is also an important opportunity for China's automobile industry to make its voice heard on the world stage.
In the next ten years or so, the Department of Vehicle Engineering of Capital Institute of Technology will be able to rely on this project to stir up troubles in the automotive industry and bring various benefits to countless people.
At that time, a large number of associate professors and assistant professors who follow Zhu Jianming will definitely be promoted because of the success of this project.
These people will be Zhu Jiansheng’s die-hard supporters in the future.
Promoting Zhu Jiansheng to continue to reach high positions is an important plan for Jiang Hui to plan for his future.
It is obviously in Jiang Hui's interest to allow Zhu Jiansheng's supporters to continue to move up.
"The new BJ212 is a key project of the Capital Automobile Manufacturing Plant. As the liaison officer of the project team office, if you take time to go to school every week, there should be opinions in the factory, right?"
Zhu Jiansheng naturally hopes that Jiang Hui can come and bring the teachers and students in the department to work on the Hummer model, but this matter must not affect Jiang Hui's status and reputation in the factory.
Otherwise, it would be a bit of a waste.
"Don't worry about this. You are the person in charge of the new BJ212. Now the caliber of my publicity is that this model was designed under your leadership. Then I will take one day a week to report to you on the progress of the new BJ212. Isn’t it a matter of course to get your support for the problems encountered during the process? "
Jiang Hui said this and felt a little embarrassed to directly mention Zhu Jiansheng.
Obviously he came to help me, but in the end, he turned to me to ask for support.
However, this is the only way to best solve Jiang Hui's attendance problem.
Although it is difficult for factories in this era to fire an employee, the Capital Automobile Manufacturing Plant will certainly not fire Jiang Hui because of his attendance problems.
But if it falls into the eyes of caring people and spreads various specious rumors, it will eventually have some bad effects.
Whether it is Zhu Jiansheng or Jiang Hui, it is obvious that they do not want to see such a situation happen.
In this era of promoting personnel, in addition to work ability, personal reputation is also very important.
If when the promotion is announced, a bunch of people write various report letters, even if the content mentioned above is false, it will easily mess up your matter.
In a word, people may not be able to succeed, but it is still very simple to fail.
"Okay, let's do it as you want."
Zhu Jiansheng agreed to Jiang Hui's plan without any further hesitation.
"By the way, the Capital Internal Combustion Engine Factory came to talk to us some time ago and wants to cooperate with us in the diesel engine for the Hummer project."
"But the power of their current diesel engine is There is no way to meet the needs of Hummer models, and a new design is needed.”
“They definitely can’t do this alone”
The engine is the heart of a car. When Jiang Hui confirmed the Hummer project with Zhu Jiansheng, he initially determined the required performance index requirements of the diesel engine.
According to this requirement, no matter whether it is the Capital Internal Combustion Engine Factory, the Shanghai Diesel Engine Factory, or the diesel engines produced by other engine manufacturers in China, there is no way to meet the requirements.
There are some products produced by some giants in the world that can meet the needs, but importing them is definitely unrealistic.
So during this period, Zhu Jiansheng has been leading the team to follow up on this matter.
Just the more information they confirmed with various domestic supporting factories, the bigger the problem they found.
Designing a new diesel engine is a big project.
There are so many domestic engine manufacturers that have not been able to solve the problem in the past ten years. It is obviously not easy for them to solve it quickly.
"Cheng Tao from Shouchi also came to see me some time ago, but I didn't give them any confirmation."
"At that time, I will talk to the teacher in charge of engine research at the school We should also have a good communication and see how to design a new generation of diesel engines."
"It depends on your arrangement whether all of them will be handed over to Shouchi for production, or the school has other plans."< br>
The engine is very important. If Hummer wants to become a classic, it must not have a "heart disease".
Since I have taken out the Hummer project as an important project for Zhu Jiansheng to expand his influence, I must make things perfect.
It should be difficult for China to produce a diesel engine that is comparable to the technical level of later generations.
But it is not a big problem to come up with a product that is barely enough for Hummer.
If you take out some of the products in Jiang Hui's memory and try them out, you can hope to significantly improve the existing diesel engine technology.
By then, maybe this diesel engine will become a flagship product of the Vehicle Engineering Department of Capital Institute of Technology. After continuous improvements in the future, it will reap dividends for more than ten years.
“As for the gearbox, for the time being, we are using the 4MT produced by the Capital Gear Factory, but some targeted adjustments are needed.”
Zhu Jiansheng thought of Jiang Hui once saying that Hummer would have to Use automatic transmission to minimize driving difficulty.
But he knows very well the level of the domestic automatic transmission industry.
Needless to say, it is impossible to find a suitable supporting manufacturer to produce just a transmission control unit in a short time.
This is the same as the ECU used in electronic injection engines. No domestic manufacturer has produced similar parts before.
If you want to start from scratch, the process is relatively long.
“The first-generation Hummer can only do this for now, but the school can also set up a special research team for gearboxes, whether it is developing manual gearbox products or doing some forward-looking research for automatic gearboxes. Research is very necessary.”
Transmission has always been a relatively weak link in China’s automobile industry.
It looks like a component made up of a bunch of gears and bearings, but in fact the technical content is very high.
The material selection and processing accuracy requirements for the various parts inside are much higher than many people imagine.
It is almost impossible for gearboxes, especially automatic gearboxes, to be developed by dismantling and copying parts designs.
You just use a high-precision three-dimensional coordinate measuring instrument to measure the shape data of each part very accurately. The performance of the final produced gearbox will definitely not meet other people's requirements.
The most important thing is that in terms of durability performance, there must be a relatively large gap.
The price of the gearbox itself is not cheap. Normal cars do not need to replace the gearbox, as long as it is maintained normally.
If a gearbox breaks down after a year and a half of use, then no car company will be willing to use it.
Even if your price is very cheap, it is of no use.
This is also an important reason why most car companies in later generations continue to purchase gearboxes from manufacturers such as Aisin and ZF.
If Capital Institute of Technology could start researching this aspect early, with Jiang Hui's help, it would still be possible to develop a 4AT automatic transmission in the next few years.
Once this kind of gearbox is successfully developed, it will be barely sufficient for the next twenty years.
This can definitely bring huge tangible and intangible benefits to the Vehicle Engineering Department of Capital Institute of Technology, and it is worth pursuing.
Zhu Jiansheng can naturally understand this aspect. "I will go back to the department to communicate first. Now everyone is busy with the Hummer project, and it is estimated that there will not be too many manpower available in a short time."
What Zhu Jiansheng said is also true. .
Although some projects are important, they are not that urgent, so they must give way to urgent projects.
But procrastinating it back and forth may end up wasting time.
How to consider the problem while weighing the pros and cons is very critical.
......
After seeing Zhu Jiansheng off, Jiang Hui continued to stay at the trial site to confirm the assembly of the prototype car.
Sometimes he rolls up his sleeves and directly works with workers to solve problems encountered during the parts assembly process, and then confirms the solution with relevant personnel such as the design department and supporting factories.
During the entire prototype car assembly process, everyone gained a new understanding of Jiang Hui's worker capabilities.
It is no problem to say that he is an all-round talent.
He can tell you everything about the parts from each supporting factory.
Whether it is the engine, gearbox, or various other parts, Jiang Hui is considered an expert.
Invisibly, his influence within the supporting factory and the Capital Automobile Manufacturing Plant has increased to a higher level.
"Mr. Chen, the first prototype has been assembled. Why don't you go over and experience it first?"
Although the entire prototype assembly process requires the completion of the assembly task of five vehicles, as long as one is completed platform, a lot of confirmation work can start simultaneously.
This can save time to the greatest extent.
“Is it finally done?”
“Let’s go and have a look!”
Although Chen Qi goes around the site every day, he is also very busy with his work. Most of the time, he just simply walks around to show that he is here.
Now that the first prototype of the new BJ212 has been officially assembled, he must be going to experience it.
Soon, a group of people arrived at the trial site.
Everyone first felt its appearance and interior, then officially started the engine and drove outside the test site for a test drive experience.
In the future, when cameras and mobile phones are everywhere, prototypes of new products will definitely need to be disguised in various ways before they are driven out of the test site.
But now it's completely unnecessary.
Even if some employees have cameras at home, they cannot bring them into the factory.
“This car drives much quieter than the current BJ212, and the whole feeling has changed a lot.”
As soon as he got started, Chen Qi felt the difference.
As the chief engineer of the factory, he has driven and ridden the current BJ212 countless times.
Chen Qi is fully aware of its various advantages and disadvantages.
The engine is noisy and air leaks everywhere in the cabin.
When the speed is fast, there may be strange noises coming from somewhere.
As for ride comfort...
In an era when the per capita number of cars is less than one for a thousand people, there is no need to mention ride comfort.
Some cars are very good.
“The various performance parameters of Shouchi’s engine have been greatly improved compared to the previous generation. While the output power has been greatly increased, the noise has dropped a lot.”
"In addition, the engine and gearbox are matched well, and the sound insulation of the engine compartment was also considered when designing the vehicle, so a significant improvement in noise is inevitable."
Jiang Hui sat on the passenger seat and gave Chen Qi a brief explanation.
In later generations, the NVH problem is a problem that many car companies focus on research and improvement.
As long as Jiang Hui puts some things into use now, he can greatly improve the silent performance of the new BJ212.
In the future, the new BJ212 is destined to be used by many county and regiment-level cadres, and the scope of use will gradually be further expanded.
Due to the increasing number of civilian application scenarios, silent performance, a parameter that was not so important before, has slowly become important.
Especially with the entry of some imported cars, in comparison, it will appear that the silent performance of those original Chinese vehicles is really poor.
Jiang Hui must arrange this work in advance.
Now judging from Chen Qi's reaction, the effect is still very good.
After all, Chen Qi can quickly experience changes in silent performance, which shows that the effect is very good.
"Efforts are in the details. Your arrangement is very good. I think the new BJ212 will definitely surprise everyone."
Chen Qi said while driving the prototype Out of the trial site.
The Capital Automobile Manufacturing Plant occupies a large area, and there is a special test track in a corner of the plant.
After Chen Qi drove the car to the test track, he immediately stepped on the accelerator and started changing gears continuously.
First gear, second gear, third gear, and fourth gear, with a slightly jerky operation, Chen Qi increased the speed to 80 or 90 kilometers an hour.
“The improvement in power performance is very obvious, and the acceleration is much faster.”
“There is no abnormal noise when the gearbox shifts gears, which is much better than I expected.”
As soon as the expert takes action, he will know whether it is there or not.
As soon as Chen Qi accelerated, he felt the huge difference between the new BJ212 and the old model.
Models of this era are often overloaded.
It is also very common for a car approved to carry five people to carry seven or eight people.
If the power performance is not good, you can obviously feel that the engine has become a lot fleshier.
Although the performance of the engine Jiang Hui upgraded to Shouchi is still far behind that of later engines of the same displacement, compared with the original product, the performance has been improved by more than 30%.
This change can be clearly felt by anyone who has driven both cars.
“It seems that Shouchi and Shoucheng Factory did not disappoint us.”
Jiang Hui did not praise the engine and gearbox too much. In fact, these two products They were all designed by him.
It would be a bit embarrassing if you were bragging.
