Li Yifan didn't want to say, and Wuyun didn't ask anymore, but according to her understanding of the young man in front of her, this guy was surprisingly bold, he said that there was such a technology, and most of the technology was not obtained from a good place.

But it's nothing, anyway, the domestic automotive R&D environment is like this, in fact, there are many technologies, not patents that have been published for a long time, anyone can study them, such as the 4AT transmission, as well as AMT and CVT transmissions, such things have long passed the patent protection period.

But why we still can't produce and manufacture in China is mainly because our material science is not up to par, and another point is that the finishing technology is not up to par, so we can't produce such things.

And Li Yifan said that he has a way, which means that he must have moved his mind crookedly in terms of materials and finishing, and Wuyun has no objection to this.

After all, we are much worse than foreign countries in this regard, if we really want to follow the footsteps of foreigners step by step, we don't know when we will be able to catch up, and if we use a small trajectory and take a shortcut, it is understandable.

After discussing some research and development matters about this micro-surface with Wuyun, Li Yifan said goodbye and left the design studio, his recent itinerary is very close, and after completing these things in the capital, he has to go back to Chenhua Automobile to have a look.

For Chenhua Automobile, he doesn't often work anywhere. But he's been keeping an eye on the company. Although there is Wang Zhongfa in management. It's also very reassuring, and it's on track now, but after all, this is a company with a very high status in his heart, so it's still necessary to pay more attention.

When he returned to Chenhua Automobile, the reporters who came to Chenhua Automobile for interviews were almost gone, and he did not go to greet those reporters.

After all, he is now the big boss of this company, and although those reporters are powerful, they are not enough for him to come forward to greet him personally.

After returning to Chenhua Automobile. He went to the company's R&D department successively.

In fact, there are two main places, one is the engine research and development department, and the other is the transmission research and development department, and 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 it has been handed over to the people in these two departments, and it is currently in full swing to absorb it.

Saab's turbocharged engines are still famous around the world, but in this day and age, turbocharged engines are not yet the mainstream engines.

After all, Volkswagen has been sticking to this technology. However, the problem of burning engine oil in Volkswagen's engine has not been solved. Moreover, turbocharged engines are expensive to maintain, which is a major reason why many consumers are reluctant to use turbocharged engines.

Another reason is the turbocharger, because the current material science is not in place, so the turbocharger can not reach 200,000 kilometers of life like later generations, generally about 50,000 kilometers to replace a turbine, and the price of the turbo is very expensive, so the current turbocharged engine is not enough to become a mainstream product.

Of course, Volkswagen's turbocharged engine is still very famous in China, and it has always been a representative of the tall, the reason why this is the case, is because of their uninterrupted advertising investment, and there are many elements in it.

Many Chinese people who don't understand cars think that the use of turbocharged engines is very high, but they don't know why this kind of engine is not popularized abroad, so this has caused the consequences that Volkswagen's turbocharged engine is very famous in China.

And in this year, in fact, in the world, turbocharged engines are not the mainstream.

But the turbocharged engine is about to become mainstream, but it is already faintly showing signs of it.

After all, developed countries such as the European Union, the United States, and Japan have higher and higher requirements for environmental protection, especially for greenhouse gas emissions, which have gradually increased 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 used force in Iraq, resulting in a sharp rise in international oil prices, coupled with the development of China, the sharp rise in oil demand, these will be the main factors leading to a sharp rise in oil prices.

Especially after 2008, after the United States detonated a worldwide economic crisis, in order to stimulate the domestic economy, Americans began to print dollars and pass on the oil crisis to the world.

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

Everyone's requirements for the performance of the car are getting higher and higher, the displacement of the engine is getting smaller and smaller, and the power shortage cannot be reduced, and even there must be an improvement.

More than ten years later, it was the era when turbocharged engines had become a general trend, and even Mercedes-Benz and BMW, which had always insisted on being their own, had to give up the naturally aspirated engines that they had always insisted on, and began to develop turbocharged engines instead.

And even the Americans, who originally didn't care about fuel consumption and always liked V8 engines, had to turn around and start developing turbocharged engines with small displacements.

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

And China has always been weak in the field of turbocharging, but now Li Yifan has got a lot of Saab's unique technology from Saab, if he doesn't eat these technologies thoroughly, one step ahead of others in the future, then he is really in vain.

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

This Liang Qiming can be regarded as a lifelong engine, the earliest time was in FAW, but at that time, the leaders of FAW did not attach importance to their own research and development.

So his job at that time, most of the time, was to take apprentices, waiting for opportunities, and in those days, his daily work was to disassemble the Volkswagen engines over and over again and put them back.

From the 1.6 naturally aspirated engine used on the old Santana, to the 1.8T, 2.2L and a series of engines used on the Passat and Audi later, he has studied it all over and over again.

It's a pity that he didn't wait for the opportunity to engage in research and development by himself, and finally couldn't bear the loneliness anymore, so when Yang Rong went to hook up at that time, he didn't think much about it at all, and directly jumped ship with his apprentices.

After coming to Chenhua Automobile, the engine research room of Chenhua Automobile is even clearer, this company did not have a decent engine research department at all, and even if there was, it was just a grass team.

So at the very beginning, he personally built the engine research room of Chenhua Automobile, and Yang Rong was also very powerful, directly built two research buildings for him, and recruited hundreds of students for him.

Moreover, the main owner introduced Mitsubishi's 4G series engine from Japan, although this engine has been emasculated with a lot of key technologies, but it is still very interesting.

Then Lao Liang's job was to change his thinking from the new, and always turn to the German engine to study the Japanese engine.

In fact, there is not much difference between the two, after all, they are both 4-cylinder engines, and they are both machines that have been on the market for many years, so there is no secret at all.

So I quickly figured out the working principle of the machine, and then by Lao Yang's words, Dafa went to work with Germany's FEV to study a 1.8T engine.

Soon, this 1.8T engine was built with the financial support of Yang Rong and the technical support of the Germans.

Although the data is not as brilliant as Volkswagen, it is less problematic than Volkswagen burning engine oil, and the power is not much weaker.

finally got the results, but Lao Liang didn't have time to be happy for a few days, but Yang Rong had an accident, and Chenhua Automobile soon fell into a state of leaderless and scattered sand.

In the end, Yang Rong ran away, the State-owned Assets Supervision and Administration Commission appeared on the scene, and took over the provincial car and Chenhua automobile, and Lao Liang and many of his students even felt desperate.

Unexpectedly, the final result turned around, Chenhua Automobile was auctioned, and the boss who took over, don't look young, but he is a very visionary and courageous boss.

He assigned them a very clear task, since they have understood the working principle of other people's engines, they have to make their own things, such as variable valve technology, or two-way, intake and exhaust.

There is also turbocharging technology and so on, these requirements sound not low.

But the boss said, give money, give technical support.

And it's really implemented, that's really money, not long after their laboratory was newly opened, the boss sent them two CNC machine tools, some special materials, and twenty engines, all over the 1.5 to 2.4 liters displacement range.

This is real money, you must know that 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, as well as turbocharging technology, to put it bluntly, the principle is very simple, that is, add some small plug-ins to the engine, and then continue to test the data, and then find the best working range from these data.

Let the computer record it, and then enter it into the ECU, and monitor the working condition of the engine from time to time.

To put it bluntly, I just want you to brush the ECU, but this is indeed the most boring, and the most financially and time-consuming work, the previous FAW, no time, no energy to do it, even Yang Rong has never given them such a lot of support to do this. (To be continued......)
