If you cheat, money will follow

After leaving the Pingtou Ge Research Institute, Chang Le and Zeng Xi went to the Leda Automobile Production Base.

Entering the power workshop of the R&D center, R&D personnel are conducting research and development in an intense and orderly manner.

After Yu Chengdong took charge of Leda Automobile, he stepped into the role after getting familiar with it. At the same time, he brought Juchang's work style to Leda Automobile.

He personally set an example and asked board members to take the lead and refine the research and development work to a weekly basis.

It will take up to one and a half years to develop the engine and gearbox, and simultaneously develop the entire vehicle.

If there are not enough people, add more; if there are not enough, add more;

If the money is not enough, add more; if there is not enough, add more;

If you don’t have enough equipment, buy it again...

Once you succeed, a huge bonus will be placed in front of you, which can be worth several years a year;

If you fail, leave!

Such unreasonable goals and tasks, work requirements, and high-intensity rhythm make R&D personnel work hard day and night, through hardships and hardships, and in alternating rounds.

No complaints, as progress bonuses and overtime pay are very generous.

The base canteen is open 24 hours a day and serves meals around the clock.

As a result, progress continues to accelerate.

The engine layout design has been completed and has entered the detailed design stage.

At this stage, a large amount of CAE analysis, that is, computer-aided analysis, needs to be performed.

The analysis content includes: in-cylinder flow field analysis, modal analysis, strength analysis, noise analysis, system dynamics analysis, FEA analysis, fatigue durability analysis, aerodynamic analysis...etc.

Then further optimize based on the analysis conclusions until the optimization can meet the design and manufacturing requirements.

This is a very time-consuming, labor-intensive and expensive link, but it is an inevitable link.

Unless you buy a finished product and change the label!

It will be very soon, at most one week, the research and development will be completed, and announcements will begin - domestically produced independent engines.

The gearbox development progress is faster than that of the engine.

The design work has been completed and has entered the bench experiment stage.

The main projects are the transmission efficiency test, noise measurement test and static torsion strength test of the transmission assembly...etc.

Compared with AT gearboxes and CVT gearboxes, the dual-clutch gearbox has a simpler structure. When two manual gearboxes are put together, there are not too many patent traps.

What Chang Le and Zeng Xi are looking for is R&D Director Xu Mingzhi.

He discussed with the R&D staff in the R&D workshop.

"Old Xu."

"Boss, Mr. Zeng, you are here."

"Yes, can you still adapt to it during this period?"

"It's okay. The work intensity is higher than abroad, but the conditions are not worse than abroad in all aspects, so the R&D personnel can bear it." Xu Mingzhi said with a smile.

"That's good, hold on, it's really tiring at the beginning. Let me tell you something, Brother Pingtou's research institute has developed a very good material..."

Then, Chang Le told Xu Mingzhi some of the performance parameters Liu Chaoyang told him.

"Really? Boss, can I go and take a look now?" Xu Mingzhi was overjoyed.

"It's not possible now, it will take some time. Just tell me whether and how helpful this material will be for our research and development." Chang Le asked.

"Boss, Mr. Zeng, this is no longer a concept of help. I can clearly say that this is a revolutionary leap forward." Xu Mingzhi said excitedly:

"The inherent thermal properties of ceramic materials have always been the focus of major car companies and research institutions. They are naturally suitable for the working environment of internal combustion engines."

"But the disadvantage of low toughness almost destroys all its advantages."

"In order to avoid the shortcomings of low toughness, oxide ceramics, carbide ceramics, nitride ceramics, boride ceramics and other compound ceramics have been born. This is the next best choice and a detour."

"Although it has indeed improved a lot of resilience, it has not fundamentally solved the problem."

"Boss, the material you just mentioned has such amazing performance parameters, which shows that the problem has been fundamentally solved. If it is invested in the research and development of internal combustion engines, then it can be concluded that the engines in the world are divided into two categories. One is Leda Automobile of engines, one category is the other.”

"Can you tell me the specific function in detail?" Zeng Xi asked.

"Okay, Mr. Zeng, I will explain in detail." Xu Mingzhi explained:

"First of all, the thermal conductivity of ceramics is not high, heat conduction is not fast, and it has strong thermal insulation properties."

"Making the cylinder block with ceramics can greatly reduce the loss and attenuation of heat energy in the cylinder, thus greatly improving combustion efficiency and occasionally reducing fuel consumption."

"40% combustion efficiency has always been a big threshold for engine technology. But in the face of ceramic materials, 40% combustion efficiency may be just the beginning, maybe 50%, 60%, or even the legendary 70%? Of course, this is just me. Whether it can be achieved depends on actual verification."

"Second, as the boss just said, this material can work stably at 2000 degrees and will not react chemically or deform at high temperatures..."

"Then the engine cooling system does not need to be so complex and sophisticated in design. It cannot be eliminated, but it can be greatly simplified."

"This can not only maintain combustion efficiency, but also reduce the weight of the engine by at least 30%. The industry has always believed in the concept of "lightweight is king". It is better to lose 10 horsepower than to increase 1 kilogram."

"Third, ceramic materials are known for their high hardness. In terms of hardness, they almost surpass most metal materials. They are also corrosion-resistant and have difficulty in chemical reactions with third parties."

"As long as the toughness problem is solved, the engine calibration can be more radical. The performance will easily surpass the same level of displacement without worrying about reliability and safety."

"The Mercedes-Benz AMG series, BMW M series, and Audi RS series are not absolutely technologically advanced, but they use a large amount of alloy materials to build key components such as cylinder blocks and cylinder liners."

"By the way, boss, Mr. Zeng, I think the most important thing is cost. Boss, is this material expensive?"

"Without detailed calculations, he said the cost must be higher than cast iron, and probably slightly higher than aluminum alloy materials including processing costs..."

"That's perfect. In order to enhance reliability and stability, modern automobile engines use a large number of high-cost precious metal materials in key components such as cylinder liners, cylinder blocks, connecting rods, valves, and crankshafts..."

"If this part can be replaced by ceramics, it can save a lot of costs, and cost is the only way to win the competition."

"In addition, the problem of overheating and stalling in dual-clutch gearboxes is ultimately caused by thermal attenuation caused by repeated contact and friction of the clutch plates, and ceramic materials can effectively solve this problem."

"Boss, please provide this material as soon as possible. The fault tolerance rate of this material is too high. It can continuously speed up our research and development process. Perhaps it can be further advanced within the time limit set by Mr. Yu..."

"Boss...hey, don't leave."
