Chapter 143 Hello! New BJ212
"The Hummer model is destined to be a series of models in the future, and the most important thing is to develop the chassis-related parts well."

"Then the powertrain must not fall behind. As long as these two aspects are in place, the other aspects will not be affected much."

"I'll come to the school next Tuesday to solve some of the major bottleneck parts problems first."

"From now on, I will find one day a week to come to school and work with everyone on the Hummer project."

When his father-in-law comes to ask for help, Jiang Hui must give his full support.

After the Hummer is produced, it is destined to become a classic of the era and 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 Vehicle Engineering Department of Capital Institute of Technology can rely on this project to stir up the automotive industry and bring various benefits to countless people.

By then, a large number of associate professors and assistant professors following 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.

Pushing Zhu Jiansheng to continue to move towards higher positions is an important part of Jiang Hui's plan for his future.

Then 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 out to go to school every week, the factory will probably have some opinions, 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 loss.

"Don't worry about that. You are the person in charge of the new BJ212. Now my publicity is that this model was designed under your leadership. So I will take one day a week to report to you the problems encountered in the promotion of the new BJ212 and get your support. Isn't this a matter of course?"

Jiang Hui's words made Zhu Jiansheng feel a little embarrassed.

He clearly came here to help me, but ended up asking me for support.

However, this is the only way to best solve Jiang Hui's attendance problem.

Although it is difficult to fire an employee in a factory these days, Capital Automobile Manufacturing Plant would certainly not fire Jiang Hui because of his attendance problem.

But if it falls into the eyes of someone with ulterior motives and is spread with various specious rumors, it will eventually have some bad effects.

Neither Zhu Jiansheng nor Jiang Hui obviously wanted to see such a situation happen.

In this day and age, when promoting people, in addition to work ability, personal reputation is also very important.

If, when the time comes for the promotion announcement, a bunch of people write various letters of complaint, even if the content in them is false, it can easily ruin your cause.

In a word, people may not be able to accomplish things, but it is very easy for them to fail.

"Okay, let's do as you wish."

Zhu Jiansheng didn't hesitate any longer and agreed to Jiang Hui's plan.

"By the way, the Capital Internal Combustion Engine Factory came to us a while ago to discuss cooperation with us on the diesel engine for the Hummer project."

"But the power of their current diesel engines cannot meet the needs of the Hummer model. A completely new design is needed."

"They certainly can't do this on their own."

The engine is the heart of a car. When Jiang Hui confirmed the Hummer project with Zhu Jiansheng, he preliminarily determined the performance requirements of the diesel engine.

According to this requirement, no diesel engines produced by the Capital Internal Combustion Engine Factory, the Shanghai Diesel Engine Factory, or other engine manufacturers in China can meet the requirements.

There are some giant companies in the world that produce products that can meet this demand, but importing them is definitely unrealistic.

So during this period of time, Zhu Jiansheng has been following up on this matter with his team.

The more information they confirmed with domestic supporting manufacturers, the bigger the problem they found.

Designing a completely new diesel engine is a huge project.

It is obviously not easy for them to quickly accomplish something that so many domestic engine manufacturers have not been able to accomplish in the past decade or so.

"Cheng Tao from Shuuchi also came to see me some time ago, but I didn't give them any definite information."

"When the time comes, I will have a good discussion with the teacher in charge of engine research at school to see how to design a new generation of diesel engines."

"Whether the production will be handed over to Shuuchi or the school has other plans will depend on your arrangement."

The engine is very important. If the Hummer wants to become a classic, it must not have a "heart disease".

Since I have chosen the Hummer project as an important project for Zhu Jiansheng to expand his influence, I must do it perfectly.

It would be difficult for China today to produce a diesel engine that can rival the technological level of later generations.

But it shouldn't be a big problem to come up with a product that can barely satisfy Hummer.

If Jiang Hui just takes out some of the products in his memory and tinkers with them, it would be possible to significantly improve the existing diesel engine technology level.

By then, this diesel engine may become a flagship product of the Vehicle Engineering Department of Capital Institute of Technology, and after continuous improvements in the future, it will reap dividends for more than ten years.

"For the gearbox, we are currently using the 4MT produced by the Capital Gear Factory, but we need to make some targeted adjustments."

Zhu Jiansheng remembered that Jiang Hui once said that Hummer would use automatic transmission in the future to minimize the difficulty of driving.

But he is very clear about the level of the domestic automatic transmission industry.

Needless to say, it would be difficult to find a suitable manufacturer to produce a transmission control unit in a short period of time.

This is the same as the ECU used in electronic fuel injection engines. No domestic manufacturer has produced similar parts before.

If you want to start from scratch, the process will be long.

"The first generation of Hummer can only be like 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 on automatic gearboxes, it is very necessary."

The gearbox 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 it has very high technical content.

The material selection and processing precision requirements of the various parts inside are much higher than many people imagine.

Even for gearboxes, especially automatic gearboxes, it is almost impossible to complete research and development by disassembling and copying the design of parts.

Even if you use a high-precision three-coordinate measuring machine to measure the appearance data of each part very accurately, the performance of the gearbox you finally produce will definitely not meet other people's requirements.

The most important thing is that there will definitely be a big gap in durability.

The price of the gearbox itself is not cheap. A normal car does not need to replace the gearbox, just normal maintenance is enough.

If a gearbox breaks down after a year or two, no car company would be willing to use it.

It's useless even if your price is very cheap.

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 the Capital Institute of Technology could start researching this area early, with the help of Jiang Hui, it would still be possible to develop a 4AT automatic transmission in the next few years.

Once this type of gearbox is successfully developed, it will be sufficient for the next 20 years.

This can definitely bring huge tangible and intangible benefits to the Vehicle Engineering Department of Capital Institute of Technology, and it is worth working on it.

Zhu Jiansheng could understand this. "I'll go back and talk to the department first. Everyone is busy with the Hummer project now, so I don't think we can spare too many people in a short period of 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 if you keep procrastinating, you may end up wasting time.

How to weigh the pros and cons to consider the problem is crucial.

……

After seeing Zhu Jiansheng off, Jiang Hui continued to stay at the test site to confirm the assembly of the prototype vehicle.

Sometimes he would roll up his sleeves and work directly with the workers to solve problems encountered during the parts assembly process, and then confirm the solutions with the design department, supporting factories and other relevant personnel.

During the entire process of assembling the prototype vehicle, everyone gained a new understanding of Jiang Hui's workmanship.

There is absolutely no problem in saying that he is an all-round talent.

He can tell you everything about the parts of each supporting factory.

Whether it is the engine, the gearbox, or other parts, Jiang Hui is considered an expert.

Invisibly, his influence within the supporting factories and Capital Automobile Manufacturing Plant reached a new level.

"Chief Engineer Chen, the first prototype has been assembled. How about you go over and experience it first?"

Although the entire prototype assembly process requires the completion of five vehicles, as long as one vehicle is completed, many confirmation tasks can be started simultaneously.

This can save time to the greatest extent.

"Finally finished?"

"Come on, let's go take a look!"

Although Chen Qi would go to the site every day, he was very busy with work, so most of the time he would just take a simple walk around to show that he was there.

Now that the first prototype of the new BJ212 has been officially assembled, he will definitely go and have a good experience with it.

Soon, the group arrived at the trial site.

Everyone first got a feel for its exterior and interior, then officially started the engine and drove to the test site for a test ride.

In the future, with cameras and mobile phones everywhere, prototypes of new products will definitely need to be disguised in various ways before they can be driven out of the test site.

But now it is totally unnecessary.

Even if some employees have cameras at home, they cannot bring them into the factory.

"This car is much quieter to drive than the current BJ212. The whole feeling has changed a lot."

As soon as he started, Chen Qi felt something different.

As the chief engineer of the factory, he has no idea how many times he has driven and ridden the current BJ212.

Chen Qi is fully aware of its various advantages and disadvantages.

The engine is noisy and there are air leaks everywhere in the car.

When the speed is fast, you never know where strange noises may be heard.

As for ride comfort...

In an era when the average car ownership per person is less than one,000, there is no need to talk about riding comfort.

Some cars are very good.

"The various performance parameters of the engine at Shuuchi have been greatly improved compared to the previous generation. While the output power has been greatly increased, the noise has been reduced a lot."

"In addition, the matching between the engine and the gearbox is done well, and the sound insulation of the engine compartment is also considered when designing the whole vehicle, so a significant improvement in noise is inevitable."

Jiang Hui sat in the passenger seat and gave Chen Qi a brief explanation.

In later generations, NVH issues have become a focus of research and improvement for many car companies.

As long as Jiang Hui puts some things into use, the noise reduction performance of the new BJ212 can be greatly improved.

In the future, the new BJ212 is destined to be distributed to many county-level cadres for use, and its scope of use will gradually expand.

Due to the continuous increase in civilian application scenarios, quietness performance, a parameter that was not so important before, has gradually become important.

Especially with the entry of some imported cars, the noise reduction performance of those original Chinese vehicles seems to be very poor in comparison.

Jiang Hui must arrange this work in advance.

Judging from Chen Qi’s reaction now, the effect is still very good.

After all, Chen Qi was able to quickly experience the change in silent performance, which showed that the effect was very good.

"Your work is reflected in the details. Your arrangement is very good. I think the new BJ212 will definitely bring surprises to everyone."

As Chen Qi spoke, he drove the prototype car out of the test site.

The Capital Automobile Manufacturing Plant covers a large area and has a dedicated 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, fourth gear, with slightly awkward operation, Chen Qi increased the speed of the car to eighty or ninety kilometers per hour.

“The improvement in power performance is very obvious, and the acceleration is much faster.”

“There was no unusual noise when the gearbox shifted gears, which was much better than I expected.”

Experts will know if there is one as soon as they take action.

As soon as Chen Qi accelerated, he felt the huge difference between the new BJ212 and the old model.

Car models of this era are often overloaded.

It is very common for a car that is 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 much sluggish.

Although the performance of the engine that Jiang Hui upgraded for the first vehicle is still far behind the later engines of the same displacement, it has achieved a performance improvement of more than 30% compared to the original product.

Anyone who has driven either car can clearly feel this change.

"It seems that Shuuchi and Shouchi Factory did not disappoint us."

Jiang Hui did not praise the engine and gearbox too much, as he was actually the one who designed these two products.

It would be a bit embarrassing to brag about myself.
