"Qin Gong, from the perspective of environmental protection, is the turbocharged engine the best choice?" Piëch asked.

"That's right, turbocharged engines will definitely be a trend. We and GM's technology research and development center plan to develop advanced turbocharged engines." Qin Shaoyou said.

These words also mean that the Germans are disgusting. Anyway, the Germans will never engage in engine research and development with their own side. The Germans want to have all the technology in their hands and do not want to share it with others. Therefore, Qin Shaoyou also You can say it openly to stimulate the Germans.

In fact, although the other party is asking questions, in fact, the other party has already started to make arrangements.

Audi also belongs to the public, so when it comes to turbocharged engines, the history of public use is not too late. In 1975, Audi had its first turbocharged engine, and in 95, that is Two years later, Volkswagen's 1.8-liter five-valve turbocharged engine will be built.

Judging from this time, Volkswagen's turbocharged engine is currently being tested.

Speaking of Volkswagen's engine, many people will sneer at it, such as burning oil, carbon deposits, turbocharger failure, etc., and devaluing this engine as worthless. In fact, turbocharging technology is simply It is not a new technology. During World War II, this technology has been widely used.

Aircraft during World War II still used piston engines. In order to be able to fly to high altitudes, a supercharger was necessary, because the air at high altitudes was thin, and only when the supercharger pumped in enough air could the engine obtain sufficient power.

Even in order to be able to reach an altitude of [-] meters, a two-stage supercharger had to be used, but there were two types of superchargers at that time: supercharger and turbocharger.

Mechanical supercharging is on the crankshaft of the engine, and the supercharger is driven by a belt. This is the most direct and has a good supercharging effect. However, it consumes the power of the engine, and the turbocharger uses the exhaust gas emitted by the engine. Although there is a lag , but it does not consume engine power.

The same is true for automobile engines. There are superchargers and turbochargers. However, with the continuous development of technology and strict requirements for environmental protection, superchargers will eventually disappear, and almost all turbochargers will be used.

The public's layout in this area is quite early, of course, it can't compare with Qin Shaoyou.

The public just did it, but what about Qin Shaoyou?Already made a series!

"We plan to use 1.5 liters and 2 liters as the basic displacement, and there are two forms of naturally aspirated and turbocharged, so that we can make four engines to meet our needs." These basic data have long been passed on. It's open, so Qin Shaoyou doesn't care if others find out, he speaks generously.

Volkswagen wants to follow up, but it is not so easy, because the engine that Volkswagen has already produced, by the time they plan to do it, it is already a matter of the new century, and it will eventually be used to dominate the world.

"After all, our Phoenix car has to have a brand new engine, so as not to be gossiped behind."

Qin Shaoyou's words were too lethal, and everyone present looked ugly.

Everyone knows how the current engine came about, but it can't be said, the guy in front of him is so arrogant, it's so irritating!

Although they were angry, they had no other choice but to ask Qin Shaoyou to continue. After all, Qin Shaoyou was a guest, and Piëch still valued this guest very much.

"In terms of engines, are you also working on modularization and platformization?" Piech asked, and he valued this point.

Qin Shaoyou nodded: "Yes, this is inevitable. In this way, we can greatly save research and development costs, and in future production, we can also greatly reduce the types of parts and components. For us, this is very important. .”

The crowd nodded.

"If the single-cylinder displacement is selected to be around 0.5 liters, can these two engines be unified to further reduce the number of parts?" At this moment, a technician asked.

Since Qin Shaoyou chose the basic displacement of 1.5 liters and 2 liters, it is of course easy to think of it, 3-cylinder 1.5, four-cylinder 2.0, so that the number of parts can be further reduced, and the parts of these engines can be connected to each other. Swap is quite beneficial for car companies.

The fewer components an automaker purchases, the lower the cost.

But what about the user?

Qin Shaoyou looked at the technician and said: "This is indeed a way of thinking, but the vibration of the three-cylinder engine is too large, and it takes a lot of energy to study, so we have no plans to do so for the time being. If you have technical strength, You can try it."

Anyway, it wasn't Qin Shaoyou who proposed it. If the other party wants to go to the muddy water of the three tanks, of course he can try it.

BMW was the first to eat crabs. BMW is this way of thinking. Three cylinders and four cylinders have a basic displacement, which greatly reduces the number of parts purchased by car companies and saves money.

However, the savings will not benefit consumers, but only allow them to make more money. The other two Mercedes-Benz and Audi have not been damaged.

Even the small-displacement engine used by Mercedes-Benz is still a four-cylinder.

BMW can do this without affecting sales. It is because BMW has brand appeal. If other car companies follow suit, they will definitely die.

BMW is also wronged enough. For a long time, the low configuration of BMW 3 used three cylinders. Later, BMW felt that it couldn’t stand it, so when it was time to change the model, it was upgraded and all became four cylinders. Cylinder engine, but for the sake of distinction, low-end cars have been tuned to 156 horsepower.

As a result, the spraying was even worse. A 2.0 engine without a turbo can output this kind of power. You have a turbo, and you still have this little power. Isn’t it too shabby?Thus, the infamy of turbo decompression came out.

In fact, even if it is a turbo decompression, it is better than a three-cylinder with a low configuration, right?But the sprayers don't care about these, as long as they spray well, it can show how much they know about cars.In fact, the low-end cars of various car manufacturers are generally released to lower the price, and they are not produced much.If you think the low configuration is turbo decompression, the upper and middle configuration will do. With 184 horsepower, what else can you say?If it doesn’t work, it’s high-end, with more than 200 horsepower, it’s absolutely whizzing.

Anyway, the troll is just enjoying his mouth, and he doesn't have money to buy a car, so Peng is happy and doesn't care about it at all.

In this era, there are still a lot of three-cylinder engines. For example, Xiali 1.0 uses a three-cylinder engine. However, Xiali is a low-end car after all. No one uses a three-cylinder engine. Cylinder engine, that scene is definitely very interesting!

Those car companies that study three-cylinders in later generations are different from this reason. They are not saving parts for three-cylinders and four-cylinders. Their product lines are all three-cylinders. This is because under the same displacement, three cylinders The frictional resistance of the cylinder engine is smaller, so it is easier to achieve a more ideal fuel consumption index, which is purely driven by fuel consumption.

Piëch nodded: "This is a good idea. The engine is also produced in a modular manner to reduce costs. However, it takes several years to develop an engine. We must be prudent in this technical route." Pierre Xi is not the kind of person to follow blindly. He has his own opinions. Under the current situation, it is impossible for Piëch to make a decision immediately. What Qin Shaoyou said earlier is exactly in line with Piëch's wishes. Now This is related to the life and death of Volkswagen, and cannot be changed casually.

"I heard that Qin Gong also got an impact electric car from General Motors?" Piëch changed the subject.

It seems that these guys know themselves very well!

"Yes, I planned to drive that car for thousands of kilometers, but then I gave up."

"why?"

"Recharging repeatedly in the middle consumed all my patience, so after driving for a few days, I finally decided to find a tow truck and tow it from the capital back to City S, and then decided, besides running around the city Besides, I will never drive it for long distances again.”

"Sword Comes"

Seeing Qin Shaoyou's expression, everyone present laughed, except Karl.

Carl's expression was still very calm. He looked at everyone and said, "Everyone, think about it, what is the usual use of our cars?"

Germany is already a highly developed country. Many people have cars, but they are definitely not for long-distance running. They are for urban traffic. If you want to travel in urban areas, this kind of electric car seems to be very suitable. up.

The crowd calmed down.

"Qin Gong, in the future, will electric vehicles replace our fuel vehicles? After all, they have no exhaust emissions and won't attract the attention of those environmentalists." Piëch asked.

As soon as he finished speaking, an engineer answered first: "Of course it's impossible. That kind of thing is expensive and not easy to use. How can it replace our fuel vehicles? Those things can only be toys for the rich! "

"That's right, that's it!" More people responded.

Qin Shaoyou knew in his heart that this was the gap.

It is very difficult to change a traditional car company, because this kind of traditional car company already has its own corporate culture, corporate beliefs, and a potential force. If you want to change, it will touch the The benefit of many people.

For example, if electric vehicles are to be developed, wouldn't those who have spent half their life studying internal combustion engines and gearboxes here have no food?From their own point of view, they will absolutely hate electric vehicles.

Therefore, these traditional car companies will not be the ones who really develop electric vehicles. Only by creating a new company can this situation be broken. When these new companies develop, traditional car companies will have to adapt under pressure. .By that time, they were already behind.

Volkswagen is like this. In the traditional field, it is a strong player. Relying on the domestic market, it can just lie down and make money. Every few years, it doesn’t need to change the engine. Engage in electric vehicles.

As a result, when electrification came, Volkswagen was at a loss for what to do, and the electric cars launched in a hurry were not popular at all.

When the times abandon certain people and certain enterprises, they are always ruthless.

"No one knows what the future will look like." Qin Shaoyou said: "Americans are working on electric vehicles. I heard that islanders are working on hydrogen energy. I don't know what Volkswagen is going to do?"

"We'll go our own way!"

This sentence was originally asked by Qin Shaoyou to Piech, but someone has already answered it.

No matter what kind of electric car or hydrogen energy, there is no way for them to survive.

Although hydrogen energy is also a kind of fuel, this fuel will not be stuffed into the engine for combustion. It needs to enter the fuel cell, turn it into electricity, and then provide it to the car. It can also be regarded as a kind of electric car, but it is not directly back The battery, but the hydrogen tank on the back.

"Qin Gong, you are right. No one knows what the future will look like. After all, technology is developing too fast." Piëch said: "We can't grasp the future, we can only grasp the present."

After that, who cares?Let's do a good job with the current affairs first, and now they are going to study turbocharged engines.

Anyway, it is impossible for human beings to completely leave fossil energy, and it will not be for a long time, so there is no need for him to worry about the future.

"Qin Gong, thank you very much. Some of your remarks are very far-sighted and have benefited us a lot." Piëch said: "I don't know if you have any suggestions?"

Any other suggestions?

Qin Shaoyou smiled: "Mr. Piëch, you value me too much. What I said is just casual chatter. It may not be correct. However, I know that BMW has ZF and Mercedes-Benz has its own AT transmission. Box, Audi is lacking in automatic transmission, I guess you already have an idea to make up for your own shortcomings?"

Piëch's face hardened.

What Qin Shaoyou talked about is indeed a big problem.

Their engines can be produced by themselves, but the automatic transmission is a big problem here.

"We have a self-designed cvt gearbox, which is very smooth. Our Audi's automatic gearbox is no worse than that of other car companies." An engineer said.

Qin Shaoyou was just pointing them out, but of course they were not convinced.

Qin Shaoyou nodded: "Yes, your cvt gearbox is good, but this kind of gearbox is equipped with a self-priming engine, and it will enter the era of turbocharged engines in the future. The explosive power of the engine will be very strong, and the cvt gearbox will rely on Steel belt transmission power, I'm afraid it can't meet the needs!"

All the people present were experts. Of course, they understood the meaning of Qin Shaoyou's words, and everyone became serious.
