Chapter 182: Bumps and bumps, the Hummer prototype is coming

"Based on the information Professor Zou gave you, are you confident that you can produce a new generation of bearing steel?"

Zhou Gang naturally hopes that Shougang can also launch new products, but as a professional in the industry, he is also very clear about the difficulty of developing a new steel.

It is still a little hard to believe that we can immediately develop a new product just by relying on some information provided by the other party.

If it were really that simple, then China could easily obtain some information from overseas steel mills through various means.

Thereby greatly improving the domestic steel technology level.

"I think we can give it a try. Even if we can't significantly improve the technical level of our bearing steel in the end, at least the performance will be better than the current products, so there should still be hope."

Zuo Guangsheng didn't dare to make any guarantees.

After all, the information Zou Yuan left them was relatively limited, and many details were not fully reflected in the information.

The most important thing is that according to the information he had heard, Xinggang did not successfully produce a new generation of bearing steel in one go.

It took some adjustments before they finally succeeded.

Shougang is definitely unaware of the details of the adjustments.

Even if Zuo Guangsheng went to inquire, he would most likely not be able to find out.

Although there was no patent law in that era, each factory still had some sense of confidentiality regarding the products they produced.

Especially with the economic reforms, the pressure faced by factories began to increase.

The situation in the past where people could get a stable income regardless of drought or flood will gradually be broken.

"In that case, go and give it a try."

Zhou Gang sighed in his heart. If he had known this earlier, he would have arranged personnel to cooperate seriously with the Capital Institute of Technology and the Capital Institute of Iron and Steel to carry out the tests, then there wouldn't be so many worries.

……

"Assistant Jiang, we have made some modifications to the 4MT manual transmission according to your suggestion. Now we use the bearings produced by the new generation of bearing steel, and the performance has been significantly improved."

"We will definitely not lag behind this time."

Ji Hua looked at the newly assembled 4MT with a look of confidence on his face.

Some time ago, there were problems with the 4MT that the Capital Gear Factory was supplying to Hummer military vehicles, which put him under a lot of pressure.

"I heard that you are planning to take this opportunity to enter the truck transmission market?"

As an important supplier of Capital Automobile Manufacturing Plant, Jiang Hui pays close attention to every move of Capital Gear Factory.

Trucks are China's main production vehicle type now, and future production will not be low either.

Its gearbox market is also a relatively large market.

The most important thing is that the gearboxes of domestic trucks are a little different from those of cars. In later generations, they have basically been domestically produced. On the contrary, the automatic gearboxes of cars are basically products of foreign brands.

Transmission manufacturers such as ZF, Aisin, and JATCO have basically monopolized the automatic transmission market.

This is because the truck's gearbox is generally a manual gearbox, or an AMT gearbox developed based on a manual gearbox.

This product effectively avoids many difficulties and problems of automatic transmissions, allowing domestic companies to master production technology relatively easily.

For example, Fast in later generations was very successful in the field of truck gearboxes and could compete with companies like ZF in the international market.

Now the Capital Gear Factory has the idea of ​​developing truck gearboxes, and Jiang Hui will definitely support it.

"We do have this idea, especially now that we have a new generation of bearing steel, we are more confident in producing truck gearboxes."

"Domestic trucks, whether they are produced by FAW, Second Automobile, or Hongyan and other factories, all use domestic gearboxes, but those are technologies from more than a decade ago. Compared with international advanced products, they are completely uncompetitive."

"I hope that Capital Gear Factory can make use of the production experience of 4MT and make achievements in the field of truck gearboxes, so that our truck gearboxes can gradually catch up with the international advanced level."

I have to say that Ji Hua is still somewhat ambitious.

This ambition of his also brought Jiang Hui a lot of favor.

"I think your idea is quite good. Domestic truck transmission and engine technologies are still relatively backward, and there is still a lot of room for improvement."

"China is a vast country, and with economic development, the demand for trucks will surely increase."

"There is definitely no way that existing technology can meet market demand."

"If Capital Gear Factory can be the first to launch a new generation of gearboxes that meet the needs of trucks, then the future is definitely worth looking forward to."

"Perhaps you can become a star enterprise in the First Ministry of Machine Building."

If an important part like the gearbox is made well, it will definitely make you famous throughout the country and even the world in the future.

Jiang Hui is actually quite optimistic about the Capital Gear Factory's decision.

"Some of the gearboxes we are delivering to Capital Automobile Manufacturing Plant are now sold at unplanned prices, which is equivalent to bringing some additional income to our plant."

"In addition to using part of the money to improve workers' welfare, the factory plans to invest the rest in developing a new generation of truck transmissions."

"Assistant Jiang, please give me some guidance when the time comes."

Ji Hua's words were not polite.

He really hoped that Jiang Hui could spare some time to go to the Capital Gear Factory for guidance, otherwise he really didn't know how many years it would take for the factory to successfully develop a gearbox product that met customer expectations.

It's nothing like the 4MT manual transmission, which produces results so quickly.

"If everyone communicates more, there will naturally be no problem."

Jiang Hui exchanged pleasantries with Ji Hua for a while, and then went to the Capital Internal Combustion Engine Factory next door to confirm the preparation status of the high-power diesel engine prototype.

Compared with other products, the development of high-power diesel engines is definitely the component with the highest technical threshold in the Hummer project.

Although the Capital Internal Combustion Engine Factory had produced diesel engines before, the displacement was completely different.

Many people may not be clear about the difference between small-displacement diesel engines and large-displacement diesel engines.

This is not a simple matter of enlarging the size of various parts and then producing the product.

The coordination between the cooling system, lubrication system, etc. of a large-displacement engine requires a higher level of technology and a more complex control system to ensure stable operation.

Large-displacement diesel engines are also more complex in power output and torque control, requiring more precise electronic control systems to achieve.

Moreover, due to the large displacement and high load, large displacement diesel engines require higher fuel injection pressure and more complex combustion chamber shapes to ensure full combustion of the fuel. What is more troublesome is that large displacement diesel engines have higher requirements in terms of materials and manufacturing processes.

Due to the large size and high load of components, large-displacement diesel engines need to be manufactured with materials that are higher in strength, more resistant to high temperatures, and more resistant to corrosion.

At the same time, the manufacturing process of large-displacement diesel engines has become more complex and sophisticated, requiring the use of more advanced processing technology and equipment to ensure the accuracy and performance of components.

These problems are very troublesome to solve.

Fortunately, Jiang Hui did not expect that the large-displacement diesel engines produced by the Capital Internal Combustion Engine Factory would reach the level of later generations.

"Assistant Jiang, although all the samples of our 6.5-liter turbocharged diesel engine have been produced, the processing accuracy and strength of many parts still need to be improved."

"The current diesel engine is more of a model, and its actual performance indicators are far from meeting our design requirements."

"In the next step, we plan to work hard on improving material performance, processing accuracy and structural optimization, and strive to make this diesel engine ready for mass production as soon as possible."

Compared with the sample preparation work of other parts, the situation of high-power diesel engines is not particularly ideal.

When loading, you can take out the products and confirm some size information.

However, the performance of the diesel engine is far from meeting the design requirements.

Cheng Tao is also very clear about this.

Because of this, not long after he met Jiang Hui, he took the initiative to report the situation of the high-power diesel engines in the factory.

Anyway, this problem will be exposed sooner or later. Instead of being exposed by others, it is better for him to expose it himself.

At least he could still barely win a relatively good impression from Jiang Hui.

"In terms of improving material performance, what Shounei can do is relatively limited. The main thing is to urge supporting manufacturers to improve their level in this area as much as possible."

"But in terms of improving the processing technology, I think there is still a lot of room for improvement."

"For example, this engine piston..."

Jiang Hui discussed seriously with Cheng Tao the design improvement directions of various components.

Several professors and associate professors from the Department of Thermal Energy and Power Engineering of Capital Institute of Technology nearby were also recording something very seriously.

When Jiang Hui was still in school, he was very famous in the Department of Vehicle Engineering.

As a major that studies engines, boilers and other related power products, the Thermal Energy and Power Engineering major has quite a lot of overlap with the Vehicle Engineering Department.

So many people in the department know Jiang Hui.

In addition, everyone is aware of the fact that Jiang Hui has achieved such a big fame in just over a year of work.

So now I am keeping records conscientiously.

The teachers in the universities were all recording information honestly, and the Capital Internal Combustion Engine Factory was naturally unwilling to lag behind.

It's okay if his skills are not good enough, but if his attitude is also considered bad, Jiang Hui might change his mind.

Cheng Tao and his colleagues also heard that because Shougang's attitude towards cooperation was not very good, Capital Institute of Technology and Capital Iron and Steel Institute found Xinggang to cooperate in the research and development of the new generation of bearing steel technology. Now it has achieved very good results, which is one of the most outstanding achievements of the Ministry of First Machine Building this year.

"Assistant Jiang, in order to carry out fine processing of key components such as cylinder blocks and cylinder heads in the machining workshop to ensure that the processing accuracy and surface roughness meet the requirements, and at the same time ensure the cleanliness and lubrication of each component during the assembly process, and ultimately ensure assembly accuracy and sealing, we have submitted an application report for equipment procurement to the department."

“The diesel engines we produce by then will definitely have greatly improved character.”

Cheng Tao knew that the Capital Internal Combustion Engine Factory was definitely lagging behind in today's sample confirmation work.

Other supporting factories can basically produce samples that meet the requirements.

Even if some improvements are needed, they are often the kind that can be completed in ten days or half a month.

Unlike the Capital Internal Combustion Engine Factory, the problems are quite serious. Although the prototype can work normally, the abnormal noise and the performance parameters such as the rated power, rated rotation speed, and working cycle efficiency of the diesel engine do not meet the design standards of the drawings.

This is a very embarrassing thing.

"The transformation of equipment, the improvement of workers' technical level, the improvement of material performance, and the optimization of processing technology all need to be carried out simultaneously."

"All our prototypes will be produced within this year, and then the first batch of prototypes will be assembled for testing."

"The preparation time is very tight, and Shuuchi cannot keep lagging behind."

Jiang Hui said in a rather serious tone.

If you want to be a good client or a good leader, you cannot be cheerful all the time, otherwise you will have no authority at all.

Be serious when you should be serious, and smile when you should smile.

This seems to be similar to speaking the same thing to different people.

"Shanghai Diesel Engine Factory and Jinan Automobile Manufacturing Factory have both approached us to provide diesel engines for the Hummer military vehicle project."

"But we haven't agreed to each other yet."

"The prototype of the Shuuchi must be produced by the first quarter of next year at the latest, and it must be ready for mass production by the end of next year."

"Otherwise, the military representative might want to talk to you."

Zhu Jiansheng also interjected.

Although he knew that the domestic diesel engine technology level was just that, Shuuchi's performance this time was already pretty good.

However, you still have to be strict when it is necessary, otherwise the pressure on the other party will not be great enough and the efficiency may not be satisfactory.

"It's already November, and there are less than two months left. We have tried our best to solve the problems in the assembly process of this prototype and produce a batch of prototypes with better performance to deliver to the 618 Factory."

Although the pressure was great and the time was tight, Ji Hua finally made a promise.

If it doesn't work, the engineers in the factory will work overtime.

Anyway, this year they have received an unplanned order to support the Capital Automobile Manufacturing Plant, and their profit level has improved significantly, so they can provide various subsidies and benefits such as overtime pay to those who work overtime.

In this era, as long as the money and honor are given, the fighting spirit that engineers can burst out is definitely much more exaggerated than Ling Ling Qi in later generations.

"Okay, then let's send this prototype to the 618th Factory first. Even if it's just a model, it's better than having the engine compartment empty."

Jiang Hui did not continue to force Ji Hua, but instead prepared to start the production of the first prototype of the Hummer.
