Xiao Feng and He Xiaojun's eyes changed a little when they looked at Li Xizhou.

From the initial examination, they have become a little appreciation, after all, they are also in the industry.

I also know that in terms of the current impetuous environment in China, the one I lack most is an entrepreneur like Li Xizhou who has the spirit of fighting to the death.

"Ha, I really didn't expect that Mr. Li actually had such a big sentiment and was so willing to spend a lot of money?"

Xiao Feng knew that Guan Zhenhai would not deceive him, so when he heard that Mr. Li was so willing to spend a lot of money, he couldn't help but change his attitude.

At this time, Li Xizhou on the opposite side turned red.

"Hi, Mr. Xiao, don't listen to Mr. Guan, actually I'm not that noble either. It's mainly a real estate project I invested in before. When I was halfway through, the main investor's capital chain broke and ran away."

"Only a large construction site is left, and there are more than a dozen unfinished buildings."

"Hey, I can't tell you the hardship. I also invested part of the money in this project back then, but the main investors ran away."

"I can't get my money back, so I can only get back a debt repayment building. This building has not been built, and because of the incomplete property certificate, I can't sell it."

"It just so happened that my new project was to study elevators, so I just left it to the programmers to do it."

"After all, these so-called control systems are actually a matter of experience and data accumulation, just as much as 10,000 yuan."

Xiao Feng and the others did not expect that Boss Li would be so honest and humble, and he did not brag as Guan Zhenhai said.

But the more humble he acted, the more they would look up to this guy.

"Yes! We are also in industry, so don't you know that in fact, many projects rely on the accumulation of data and experience?"

He Xiaojun is obviously very touched by Li Xizhou's words.

The most boring, but also the most basic and critical work they do in pharmaceutical research and development is both data accumulation.

When you do an experiment countless times, you accumulate thousands of sets of data.

Finally, you can select the data that best meets your needs from these thousands of data, and then watch the amount comparison of the experiment.

Finally, let’s determine what kind of portion ratio should be used for a new drug.

The same work is also applicable to the industry in mechanical engineering.

For example, in the automotive industry, when it comes to automobiles, many people know that cars need three major items, engine, transmission, and chassis.

Especially the chassis, which is even more mysterious. It involves three elements: one is the physical structure, the other is the materials used in the chassis, and the other is the training.

The physical structure is easy to understand, such as what structure is used for your front and rear suspension, McPherson independent suspension, double wishbone independent suspension, multi-link independent suspension, or car suspension.

These different physical structures will affect the driver's driving experience and the handling accuracy of the car.

There are also materials used, such as the cantilever is made of stamped thin steel plates or aluminum alloy cantilevers. These unsprung masses will affect the driving experience of the entire vehicle.

The most mysterious thing is that the chassis has been trained.

It can even be said that the most critical part of the driving quality of a car is the driving quality.

For example, many domestic cars are plagiarized German cars, and even the chassis is exactly the same from physical structure to materials, and some materials are even better than German cars.

The Germans use single-layer stamped steel plates on the rear suspension, but our domestic manufacturers use aluminum alloy cantilevers.

But when the car finally started, everyone's feelings were indeed that the materials used in your domestic car were kind, and the road was not as clear as that of the German car, and the operation was light.

When passing through the ditches, the whole vehicle is very easy and does not drag on it.

And our domestic cars, even if they use materials with kindness, can spit you out with a speed bump.

Moreover, after two years, the chassis of some domestic cars becomes loose and loose, making people feel no confidence when driving.

What is reflected here is the gap in chassis training!

Speaking of training, in the final analysis, it is how engineers plan their chassis when designing the car.

What is the distance between each cantilever and what angle is placed?

When screwing the screws, how much torque is used, how many turns to screw, and how many buttons will be loosened at that time.

As for why we do this, it is entirely because of the accumulated data for hundreds of years and the experience passed down by generations of engineers.

And in this regard, we are far from it.

It can be said that our modern cars have only been in just twenty years.

In this regard, we are still far from others.

At present, the best thing to do in chassis training is the Germans, then the Americans, and as for the Japanese.

If the Japanese are indeed very good at car engines and transmissions, everyone must admit this.

But when it comes to the advanced sense of car driving, luxury, and ordinary handling, Japanese cars are indeed a certain gap from German cars and American cars.

There is no way, this is the knowledge that requires long-term accumulation of big data to accumulate.

There is another very important point in cars, which is the matching between the engine and the transmission.

The best thing to do in this regard is the Germans and the Japanese, while the Americans are a little far behind in this regard.

To put it bluntly, it is also a 1.4T engine, the German engine can burst out the maximum torque at 1,500 rpm.

Our domestic 1.4T engine basically needs to reach more than 2,000 rpm before it can burst out the maximum torque.

This is the gap in training, and this is also the gap brought about by long-term experience and big data accumulation.

The Japanese can be said to have done the best in tuning the engine and transmission, especially Liangda.

Toyota is fuel-efficient and smooth, and the power of the Honda engine on call is all unique.

This is also the main reason why both of their cars are more popular than German cars in the used car market.

On the other hand, the United States is not a little bit short of this.

For example, the general engine and the 2.0T nose home version can achieve 285 power, and the torque is even more terrifying.

The transmission can also be made of 9-speed and 10-speed. Judging from the book data, it will definitely crush German and Japanese cars.

But as soon as I get into actual combat, I get diarrhea...

Whether it is Ford or GM, no matter how scary its engine data is, their transmission gears are several more than those of German and Japanese.

But once the car is on the road, you will find that it is not as good as the Germans at the beginning and the fuel consumption is not as good as the Japanese.

That is, in the middle and rear sections of linear acceleration, you can feel the surging power of the engine.

But in the city, which driver would drive like that?

This is the difference between the engine and the transmission, matching the tuning.

At the root of these statements, they are actually the advantages of those big companies in big data and experience accumulation.

It is precisely because Japanese and German engineers accumulate experimental data from generation to generation, and then pass on these data. Then, engineers, based on these experiences and data, have updated and iterated generations, which has created today's Japanese and German car companies.

On the other hand, our domestic car companies are really far behind in this regard.

For example, many domestic car companies now also have 6AT and 8AT transmissions developed by Toyota's royal Aisin Seiki in their main models.

This transmission looks very high-end, but when you actually use it, you will find that their matching is even smoother and smoother than the domestic 7DCT transmission.

The engine parameters look very high, but after matching with the Japanese transmission, the best power of the engine cannot explode at all.

When it starts, it often gets kicked up, and as for fuel-efficient, it can only be even more hilarious.

This is because many of our companies are not patient and too impetuous in data accumulation. They will use it directly when they are introduced from others.

On the other hand, BYD did a very good job at the beginning.

The key points of the transmission are actually just TCU and the transmission control program.

When they reversed the Volkswagen dual-clutch transmission, they dared to chew tough problems.

After understanding the principle of Volkswagen dual-clutch, he fought to the death, built dozens of units, and then ran around the track day and night.

Record various data on the matching of the transmission and engine, and finally according to what their insiders say.

A car ran millions of kilometers on the track day and night, and dozens of cars ran down like this before they could master sufficient data.

Finally, their independent TCU system was designed, and the first domestic automatic transmission was truly created.

It was also after BYD truly conquered the automatic transmission that international transmission supporting manufacturers truly opened the door to domestic cars.

What are the Gotrack, Aisin Seiki, ZF, and Bonzis have begun to supply domestic brand brands.

If it were before, people wouldn't even birds, even if they knew how to work with you to make money, they wouldn't supply you.

Because as long as they monopolize the automatic transmission, they can ensure that their car companies can earn more from China.

In contrast, the same is true for the elevator industry.

It is said that elevator control system is a big problem, but it is true.

Because you need to design various solutions and program design according to the various usage scenarios of the elevator.

For example, if the elevator carries one person to the top floor, and if the elevator carries thirteen people, they will go to thirteen different floors respectively.

Or on different floors, some people want to go upstairs and some people want to go downstairs, and the elevator happens to be running at this time.

How to do elevators and which group of users to satisfy first, these require system settings.

For different floors, different numbers of people, and different user needs, there may be hundreds of thousands of arrangements and combinations involved.

And you have to take care of these needs when you set up the system...
