The reduction of the body weight has always been the most difficult problem for European and American car designers, after all, the car design ideas they have learned since childhood are different from the Japanese, and they can't do a design plan that cares about human life like the Japanese, which is too contrary to their design concept and conscience. (It only takes 3 seconds to remember the genius)

European and American designers, when designing cars, first put the car in the category of a tool to serve people, so they think more about the safety of the car, then the handling performance, and then the comfort or luxury and so on.

However, Japanese designers are different, in the scope of their design concept, the car is a commodity, so their design concept considers more about how a car can make consumers get greater satisfaction.

The object of their research is more aimed at people, that is, the end consumers of cars, rather than cars!

After all, not all car consumers are rich, more family car consumers are thinking about how to spend the least amount of money to buy a model that can not only make them feel face, but also not weaker than or close to those in the high-end configuration, and the best cost on this car is as little as possible, such as less into the repair shop, so as to reduce a lot of maintenance expenditure.

Less oil burned, which saves money on fuel bills, etc.

The efforts of Japanese designers in this regard can indeed be said to be the pinnacle, and they can be said to be the most thorough study of the minds of consumers.

How can consumers get the most satisfaction with the least amount of money? Quite simply, the best way is to make a fuss about the material of the body.

There is no doubt that the Japanese can do a very good job of engine and powertrain, and there is a fight with European and American engines, but in terms of the weight of the car, the weight of their models is often much lighter than that of European and American models of the same level.

They can achieve such an effect is very simple, that is, in the manufacture of the body, where steel is used, 1 cm can be used, and 1.5 cm thick steel plates and steel beams will never be used, which can not only save a lot of steel, but also effectively reduce the weight of the body, so as to achieve the purpose of saving costs.

This is why you can often see in the car survey column a few years later, Japanese cars are even using foam as a collision buffer for cars, and some even save the rear impact beam.

And even if some cars are equipped with front and rear anti-collision steel beams, they use the thinnest layer of anti-collision beams, and even think of a bastard like Fuji, and even match the car with FRP anti-collision steel beams......

Such a model, if it is put in Europe and the United States, it will simply be called a careless life, so the Japanese models listed in Europe and the United States, of course, they do not dare to be as unscrupulous as the models listed in the Celestial Empire in terms of cutting corners.

But if you compare it, it's actually not much better, and where it should be thin, it must be thin enough, and it will definitely not add even 0.01% more thickness to you.

However, even such steel can basically meet the minimum body strength, or stiffness, required by European and American countries for automobiles.

After all, this is related to the developed steel smelting technology in Europe, the United States and Japan, the same thickness of steel, the tensile resistance, strength, and even rigidity of other people's steel are about 1.5 times better than the steel produced in our Celestial Empire.

This is also the reason why in later generations, everyone often sees on the Internet that many Japanese cars that had car accidents in the Celestial Empire will have broken axles, or even broken and torn whole vehicles, or even pictures that are torn apart like cardboard. …,

In the Celestial Empire, they use the steel plate of our Celestial Empire, but our steel plate cannot reach the strength and rigidity of the same grade steel plate in their own country or in Europe and the United States, so once a car accident occurs, the consequences are really terrible.

Some people may say that I didn't buy a car to crash, and I drive very carefully, I don't drive fast, and I don't drink and drive, so this kind of thing won't happen to me, Japanese cars are fuel-efficient, durable, and face-saving, and I bought them and said that they were good, then I can only advise you to really pray to God and worship Buddha when you drive in the future.

After all, the ancestors have a saying, not afraid of 10,000, just in case, and how bad the driving environment of the Celestial Empire is, and the quality of the drivers is also uneven, and those who have driven a car know it.

Sometimes, even if it's not your fault, but the car accident will still find you, once such a thing happens, then you really can only ask the gods and Buddhas to bless you.

After Peter's introduction, he finished the design of the body and structure of the car, and at this time it was time for the powertrain design of the car that the reporters were most interested in.

The design of the powertrain of the K5 was completed by Jin Xiaoqiang, so about this issue, of course, these reporters found Jin Xiaoqiang.

Originally, everyone was a little unsure that the engine of this car could achieve a compression ratio of 13:1, and even many reporters were secretly speculating whether Huayang Power was bragging.

But before, everyone was relieved when they saw Peter standing on the booth and admitted that he was one of the co-designers of the car.

Even if you can't believe Huayang Power, you can't believe Jin Xiaoqiang, and to put it bluntly, you can't believe the people of the Celestial Empire, but Peter, as a world-renowned automobile design master and one of the three famous European car designers, you can't believe him, right?

Peter stood on the stage, which means that he also has absolute confidence in this car, which means that no matter what, the 13:1 compression ratio announced by the engine of this car is absolutely true.

Jin Xiaoqiang may lie, but Peter can't lie with him, after all, Peter can't gamble on the reputation he has worked hard to build up for more than 20 years for Jin Xiaoqiang.

So at this time, the reporters who were originally full of doubts about the engine of this car have already gone to the * points, and most of them have already believed the data released by Jin Xiaoqiang and them before.

But at this time, everyone's heart feels more sour, how did this guy do it?

Even if he was a genius, he would be able to make the engine achieve a 13:1 compression ratio without using a turbocharger or a supercharger, right?

"Mr. Kim, can you give us a detailed introduction to the engine you designed for this car? How on earth was he able to achieve a compression ratio of 13:1 between air and fuel without the use of any superchargers? ”

The German reporter was reluctant to ask, because he was unwilling to give Jin Xiaoqiang a chance to show off, but he couldn't stand it at this time, and the Japanese were the first to stand up.

The ability of the Japanese to adjust their mentality is really unusual, after all, how to make cars more fuel-efficient has always been the main goal of their car research and development.

So at this time, Jin Xiaoqiang was able to achieve such a high air compression ratio without using any supercharger, which really made them feel very curious.

"Well, I have to correct that the compression ratio of 13:1 is just the data we have released to the public, in fact, according to our theoretical design, the best compression ratio that this engine can achieve is 14:1......"

As soon as Jin Xiaoqiang's words fell, there was the same chaotic scene in the audience as before. …,

The reporters couldn't help it, they got together with each other, and began to talk to each other, but at this time, they had everything to say, in short, Jin Xiaoqiang's words were able to make these reporters lively for a while every time.

"Nani? …… A compression ratio of 14:1? Soga, how the hell did this guy do it? ”

"Where's the bragging pen? 13:1 is exaggerated enough, and you can still blow 14:1 at this time, can such data be achieved by relying on your mouth? ”

"Hey! Young man, why don't you know that the sky is high and the earth is thick......"

"Humph! I don't brag and don't make drafts, wait a while, I must ask you well, how did you achieve this 14:1 compression ratio? ”

"Hey, why don't you say 15:1 or 16:1? Wait a while, Lao Tzu must make you make a fool of yourself......"

After Jin Xiaoqiang's voice just fell, the reporters in the audience were discussing a lot, and at the same time, they also secretly harbored ghosts, in short, everyone said that the data from Jin Xiaoqiang's mouth was just two words, I don't believe it!

Coupled with the previous grudge with Jin Xiaoqiang, at this time, many German reporters and Japanese reporters have gritted their teeth and waited to make Jin Xiaoqiang ugly in a while.

"Mr. Kim, how did you manage to make this car achieve both a 13:1 compression ratio and a 14:1 compression ratio?"

The German reporter took the lead in asking questions, in fact, many senior German automotive media people, like Americans, prefer naturally aspirated engines.

As for turbocharging, or mechanical supercharging, it is in recent years that with the extensive use of Japanese cars, especially the Mitsubishi and Subaru brands, a large number of turbocharging technologies have driven more consumers' enthusiasm for such technologies.

Therefore, in the past two years, supercharging technology has gradually appeared in many German models, especially Volkswagen and Audi, which are the two companies that have done the best and are the first to step into this field.

But even if they use a supercharger, let alone a 14:1 ratio, even a 13:1 compression ratio, they can't do it.

So these German reporters are really curious, how did Huayang Power achieve such a compression ratio without applying a supercharger?
