Li Yifan didn't want to say it, so Wuyun stopped asking, but based on her understanding of the young man in front of her, this guy was surprisingly brave. He said that if there was such a technology, then such technology would probably not be obtained from some good place.

But this is nothing. Anyway, this is the case with the domestic automobile research and development environment. In fact, there are many technologies that have not been published for a long time. Anyone can study it, such as the 4AT transmission, as well as the Amt and CVT transmissions. Such things have long passed the patent protection period.

But why it is still impossible to produce and manufacture in China is mainly because our materials science is not up to standard, and another point is that the finishing technology is not up to standard, so we cannot produce such things.

Li Yifan said that he had a solution, which means that he must have had bad intentions in terms of materials and finishing. Wuyun did not object to this point.

After all, we are much worse than foreign countries. If we really have to follow the steps of foreigners step by step, we don’t know when we can catch up. But if we use a small trajectory and take a shortcut, it is understandable.

After discussing some research and development matters about this micro-face, Li Yifan said goodbye and left the design studio. His recent itinerary was very close. After dealing with these things in Beijing, he would go back to Chenhua Automobile to check it out.

He doesn't often work anywhere for Chenhua Auto. But he has been paying attention to this company. Although Wang Zhongfa is managing it, it is very reassuring and is now on track, but after all, this is a company with a very high status in his mind, so it is still necessary to pay more attention.

When he returned to Chenhua Auto, the reporters who came to Chenhua Auto to interview had almost gone, and he did not say hello to the reporters.

After all, he is now the boss of this company. Although the pens of those reporters are great, he will not come forward to greet him in person.

After returning to Chenhua Automobile, he went to the company's R&D department one after another.

In fact, the main ones are two places, one is the engine R&D department, and the other is the transmission R&D department. Now, in his opinion, these two departments are the key.

A few months ago, he got a lot of mature technology from Saab, and now he has handed it over to people from these two departments and is currently absorbing it in full swing.

Saab's turbocharged engines are still very famous around the world, but in this era, turbocharged engines are not yet mainstream engines.

After all, Volkswagen has been sticking to this technology. However, the problem of Volkswagen engine burning oil has not been solved. Moreover, the maintenance cost of turbocharged engines is expensive, which is also a major reason why many consumers are unwilling to use turbocharged engines.

Another reason is the reason for this turbocharger. Because the current material science is not in place, this turbocharger cannot reach a lifespan of 200,000 kilometers like in later generations. Generally, a turbine needs to be replaced at about 50,000 kilometers. The price of the turbine is very expensive, so the current turbocharged engine is not enough to become a mainstream product.

Of course, Volkswagen's turbocharged engines are still very famous in China and have always been a representative of high quality. The reason for this is that they continue to invest in advertising and there are many elements of rumors.

Many Chinese people who don’t know how to use turbocharged engines are very generous. As for why this kind of engine is not popularized abroad, they are not aware of it. This has caused the consequence that Volkswagen’s turbocharged engine is very famous in China.

And in this day and age, turbocharged engines are not the mainstream around the world.

However, this turbocharged engine is about to become mainstream, but signs have already appeared.

After all, developed countries such as the EU, the United States, and Japan have increasingly high requirements for environmental protection, especially the requirements for greenhouse gas emissions, which have been gradually increasing in recent years.

On the other hand, it is also related to the oil crisis that is about to break out in the future. The United States has used force in Iraq, which has led to a sharp rise in international oil prices. Coupled with the great development of China, the sharp rise in demand for oil, these will be the main factors that have led to a sharp rise in oil prices.

Especially after 2008, after the United States triggered a global economic crisis, Americans began to print the dollar in order to stimulate the domestic economy and transfer the oil crisis to the world.

In the end, it led to a sharp depreciation of the US dollar and a significant increase in oil prices, which will greatly hurt the nerves of ordinary car buyers.

Everyone's requirements for the performance of cars are getting higher and higher, the engine's displacement is getting smaller and smaller, and the power is not reduced, and even more improved. Such requirements have made many car designers unable to think about the turbocharged engine.

After more than ten years, it was the era when the trend of turbocharged engines had become. Even if I insisted on building my own Mercedes-Benz and BMW, I had to give up the naturally aspirated engine I had always insisted on and began to develop turbocharged engines.

Even Americans who didn't care about fuel consumption and always liked the V8 engine had to turn around and start developing small-displacement turbocharged engines.

So by that time, turbocharged engines will naturally become the mainstream in the world's automotive industry.

However, China has always been a weakness in the turbocharger field. Now Li Yifan has obtained many of Saab's unique technologies from Saab. If he doesn't understand these technologies thoroughly and lead others in the future, he will be in vain.

So when he got these technologies and brought them back, he handed them over to Liang Qiming, who was responsible for engine research and development in the company.

Liang Qiming has been working on the engine all his life. He was at FAW at the earliest, but at that time, the leaders of FAW did not pay attention to their own research and development at all.

So when he worked at that time, most of his time, he took his apprentices and waited for opportunities. During those days, his daily work was to toss and turns to disassemble the Volkswagen's engines and put them back on.

He has studied all the engines from the 1.6 used on the old Santana, and later on the 1.8t, 2.2l used on the Passat and Audi.

Unfortunately, he didn't wait for the opportunity to do research and development after waiting. In the end, he could no longer bear the loneliness. So when Yang Rong went to hook up, he didn't think much about it and took his apprentices to jump into the job.

After coming to Chenhua Automobile, the engine research room of Chenhua Automobile was even more clear. In the past, the company had no decent engine research department at all, and even if it had it, it was just a turtle team.

So in the first period, he personally built the engine research room of Chenhua Automobile. Yang Rong was very proud and built two research buildings for him and attracted hundreds of students.

In addition, he also introduced Mitsubishi's 4g series engine from Japan. Although this engine has been castrated with many key technologies, it is still very confusing.

Then Lao Liang's job was to change his ideas, and to switch from the original German engine to the Japanese engine.

In fact, there are not many differences between the two companies. After all, they are both 4-cylinder machines, and they are machines that have been on the market for many years. There is no secret.

So I quickly figured out the working principle of the machine, and then after Lao Yang said, Dafa joined hands with German Fev to study a 1.8t engine.

Soon, this 1.8t engine was built with Yang Rong's financial support and the technical support of the Germans.

Although the data is not as outstanding as Volkswagen, it lacks the problem of Volkswagen burning engine oil, and its power is not much weaker.

Finally, the result was achieved, but before Lao Liang could be happy for a few days, something happened to Yang Rong, and Chenhua Automobile soon fell into a state of headlessness and loose sand.

In the end, Yang Rong ran away, the State-owned Assets Supervision and Administration Commission appeared, taking over Provincial Capital Automobile and Chenhua Automobile. Lao Liang and many of his students were even desperate.

Unexpectedly, the final result was a turnaround. Chenhua Auto was auctioned off. The boss who took over, although he was young, was a very visionary and courageous boss.

He assigned them very clear tasks. Since he already understood the working principle of other people's engines, he had to come up with his own things, such as variable valve technology, or both, and inlet and exhaust.

There are also turbocharger technology, etc., and these requirements sound not low.

But the boss said, give money and technical support.

And it has really been implemented. That is really a money. Not long after their laboratory was newly opened, the boss brought them two CNC machine tools, some special materials, and twenty engines, covering a displacement range of 1.5 to 2.4 liters.

This is real money. You know, he has been engaged in engine research and development for so many years, but he has never seen that boss so generous.

In fact, these, such as variable valve technology and turbocharger technology, are very simple to put it bluntly, which is to add some small plug-ins to the engine, then uninterrupted test data, and then find the best working range from these data.

Let the computer record it, then enter the ecu to monitor the engine's working conditions in a timely manner.
