In fact, this can't be blamed on the short-sightedness of these engineers, after all, for their gang, even the variable valve timing and lift technology is already quite tall now.

Not to mention in China, even in the world, the mainstream of automobile engines is still in the era of naturally aspirated flatbed machines, even if it is this variable valve timing and lift technology, it is already quite advanced Wagyu breaking technology.

And playing turbocharging is already quite awesome.

This boss, to put it lightly, is to let everyone engage in mechanical superchargers, that's all, and now let everyone do direct injection in the cylinder, isn't this a bit too much?

To put it bluntly, isn't it too ambitious?

After all, they don't have Li Yifan's more than ten years of life experience than now, if they have, they will know that in ten years, these three technologies that they now regard as tall will be the specific technical characteristics necessary for the engine of any ordinary middle-class car.

Ten years later, variable valve lift and timing technology like this one is already a bad street technology, and even for many domestic cars, these are necessary technologies.

And turbocharging, there are also many domestic independent car companies can afford to play, as for direct injection technology.

This is quite tall, in China, out of BYD. There really isn't a self-service car company that can afford to play.

And to be able to knead these three technologies together. That's called more bullishness.

Volkswagen was the first to come up with the TSI, and then Ford followed. And it came from behind, and GM and so on also followed suit.

Even BYD has come up with such an engine, and other domestic car companies also want to follow up, but they suffer from insufficient technical support, so they can only stare dryly.

As for those Japanese car companies, the reason why they began to gradually decline after ten years is because they did not follow up in time in the field of engines.

Everyone else is playing with the tall of integrating these three technologies into one engine. They are still making a fuss with their naturally aspirated engines.

Although such engines are more reliable and cheaper to maintain, they ignore a very important element, that is, consumer user experience and consumer psychology.

So their future is destined to be lonely, of course, it will not change at home, but internationally. It's hard to say.

After all, Japanese cars, over the years, have also accumulated a lot of contacts and reputation.

And Li Yifan's Chenhua Automobile, because of the late start. And if he wants to challenge the position of Volkswagen and Japanese cars in the domestic market, then he must make a fuss about technology.

Even technically, you can't surpass your opponents. Then at the very least, you must be able to be on par with each other.

Therefore, his requirements for technology can be said to be extremely crazy. Even the level of obsession.

The engineers of the power R&D department have such an attitude towards the boss. said that he didn't understand very much, although he agreed to the boss's request on the surface.

But he didn't pay much attention to it, Li Yifan was not a fool, and of course he could see the attitude of these guys.

So he decided to give the guys a little bit of excitement, and he found a kung fu that day, and then spent a sketch, which was a sketch of a supercharger.

If someone is like Li Yifan who crossed over from ten years later and sees this sketch of his skating, then they will definitely scold this guy for his shamelessness.

Because this sketch he drew is the sixth-generation twin-scroll supercharger of Eaton, which was widely used in high-end luxury models more than ten years later.

The people present are all professionals who have been studying the field of engine research and development for many years, so they can almost tell at a glance whether something is good or bad.

The supercharger has been born more than 100 years ago, and its working nature is the same as that of the turbine, which is through an external plug-in from the outside world, rotating and then accelerating the air circulation, so that the engine cylinder can enter enough air at a time, so that the gasoline can be more fully burned in the cylinder, so that the engine bursts out more powerful power.

It's just that the turbocharger drives the rotor through the exhaust gas removed from the engine, and then the rotor drives the fan blades on the other side to increase air circulation.

The supercharger is to add an external plug-in on one side of the engine, and at the same time as the engine rotates, the external rotor is driven by the belt, so as to achieve the purpose of accelerating air circulation and allowing more air to pour into the cylinder.

But compared to the turbocharger, this kind of thing has obvious advantages, that is, it has no turbo hysteresis effect, and it will start working at the same time as the engine works, so the effect of this plug-in is very obvious in the early days of the car.

But it also has two very obvious shortcomings, one is that he consumes the power of the engine, so it will consume more fuel, and the other is this kind of plug-in, when the engine reaches a certain number of revolutions, his utility will not be particularly obvious.

After all, the weight of this plug-in is heavier than that of a turbocharger, and it is also larger, so the additional effects it can produce will be offset by the consumption it generates after reaching a certain number of revolutions.

So it didn't take long for this thing to stop being popular.

Later, it was used in large trucks for a while, but it never became mainstream.

After entering the 80s of the last century, it went into decline even more, and the Yankees, who like to play the straight-line acceleration race, are still insisting on this kind of thing, and basically no one will develop this kind of thing anymore.

Volkswagen's recently hyped TSI concept is to install a supercharger and then a turbocharger on one engine.

In this way, with the intervention of the supercharger, the turbo hysteresis effect of the turbocharger can be significantly reduced.

And they also use the fourth-generation supercharger from Eaton in the United States.

What Li Yifan is painting now is the sixth-generation product that made Eaton turn around more than ten years later, this supercharger, which was later used in many high-end models.

For example, Audi's 3.6-liter engine, Chrysler's high-end engine, Ford's Mustang, etc., all use this supercharger in famous models.

The biggest feature of this supercharger is that it has changed the fixed single scroll mechanism of the current supercharger, from the original one rotor to two rotors, which greatly improves the efficiency of mechanical supercharger.

THE PRESSURE THAT SUCH A ROTOR CAN PRODUCE CAN BE AS HIGH AS ABOUT 10 BAR, WHICH IS ENOUGH TO MEET THE REQUIREMENTS OF ANY ENGINE FOR AIR COMPRESSOR.

ALTHOUGH IT IS NOT COMPARABLE TO THE PRESSURE VALUE OF THE TURBOCHARGER, WHICH IS OFTEN TENS OF BAR, IT IS ENOUGH TO BE ABLE TO ACHIEVE SUCH A VALUE.

And with such a value, it is completely possible to eliminate the trouble of turbo hysteresis, and it can also meet the needs of the car for large air intake from start to finish.

This is definitely a commendable artifact, which is the main reason why such a thing was later installed in so many luxury high-end models.

And those engineers who were originally quite unconvinced by Li Yifan, after reading the sketch he drew, those who were smarter and figured out the trick in it were convinced, even if there were still those who didn't understand, but at least they understood the benefits of this thing.

This shows that the boss on the other side is not a straw bag who can only point fingers, he still has some expectations.

After shaking off the somewhat arrogant engineers, Li Yifan definitely held a meeting to give a speech to the engineers.

"Brothers, the reason why I call you that is because we are one big family. And now we all come together with one goal, that is, to develop our own best car. You are all automotive engineers, and you should know better than me how good and how good a good engine must be. ”

Li Yifan's words made the engineers fall silent.

Indeed, as practitioners in this industry, they should know better than Li Yifan what kind of car is a good car and what kind of engine is a good engine.

"Now we are just getting started, and it is not an exaggeration to say that we are poor and white. You know better than I know how strong our opponents are. The advantages of Japanese car engines are precision, good stability, and strong fuel efficiency. And Volkswagen, they have even been the first in Europe to launch the TSI engine, what that means, I think you also know better than me, can change the valve lift and timing, as well as turbocharging and supercharging, as well as direct injection and other technologies that currently represent the most cutting-edge technology in the automotive industry, all together, which shows the strength of others. Look at us again, we are even the most ordinary naturally aspirated engine, which is in its infancy, and we can't compare with others? ”

Li Yifan's words made the engineer team present stop talking, and even Liang Qiming's mood became heavy all of a sudden, because everyone knew that what Li Yifan said was the truth.

"But, is it because people @ points are higher than us, and the technology is better than wondering, so we have to be discouraged and give up this competition? Do you want to see that all the streets and alleys in China are running joint venture cars with foreign car logos? Aren't we Chinese people called by foreigners the most intelligent and hard-working people? Can we swallow this breath? (To be continued......)
