Reducing the weight of the car body has always been the most difficult problem for European and American car designers. After all, the car design ideas they learned since childhood are different from the Japanese, and they cannot be as careless about human life as the Japanese.

It goes against their design philosophy and conscience.

When European and American designers design cars, they first place the car in the category of a tool that serves people, so they consider more about the safety of the car, then the control performance, and then comfort or comfort.

Luxury and other issues.

But Japanese designers are different. In their design philosophy, cars are commodities, so their design philosophy considers more how a car can give consumers greater inner satisfaction.

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

After all, not all car consumers are rich. What more home car consumers consider is how to spend the least money to buy a car that can not only make them feel good, but also have good performance.

It is not weaker than, or close to, those models with mid-to-high-end configurations, and it is best to spend as little as possible on this car, such as fewer visits to repair shops, which can reduce a large amount of maintenance expenses.

Burn less oil, which saves fuel expenses, etc.

The efforts made by Japanese designers in this area can indeed be said to be at the pinnacle. They can be said to be the group of people who have studied the minds of consumers most thoroughly.

How can consumers spend the least money and get the greatest satisfaction? The simplest and best way is to make a fuss about the materials of the car body.

Engines and powertrains. There is no doubt that the Japanese can do a very good job and can compete with European and American engines. However, 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.

.

The effect they can achieve is very simple. When manufacturing the car body, where steel is used, if 1 cm is used, 1.5 cm thick steel plates and steel beams will never be used. This can save a lot of steel.

, and can effectively reduce the weight of the car body, thereby achieving the purpose of saving costs.

This is why you can often see in the car survey columns a few years later that Japanese cars are even using foam as the anti-collision buffer zone of the car. Some even save the rear anti-collision 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. Some bastards like Fuji even equip their cars with fiberglass anti-collision steel beams.

..

If such a model were introduced in Europe and the United States, it would simply be called a waste of human life. Therefore, Japanese models launched in Europe and the United States certainly do not dare to be as unscrupulous in cutting corners as models launched in China.

But if you compare it, it's actually not much better. Where it should be thin, it must be thin enough. You will never be given even 0.01% more thickness.

However, even this kind of 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 advanced steel smelting technology in European, American and Japanese countries. For the same thickness of steel, the tensile strength and strength of their steel are 1.5 times better than the steel produced in China.

About times.

This is why in later generations, you often see on the Internet that many Japanese cars that were involved in car accidents in China had broken axles, or even the whole car was broken and torn apart. There were even pictures that were torn apart like cardboard.

for the sake of.

In China, they use steel plates from China, but our steel plates cannot reach the strength and rigidity of the same grade of steel plates from their home country or Europe and the United States, so if there is a car accident, the consequences will be really terrible.

Some people may say that I didn’t buy a car just to crash, and I drive very carefully, I don’t drive too fast, and I don’t drive drunk, so this kind of thing won’t happen to me. Japanese cars are fuel-efficient, durable, and

Since you agreed to buy it to save face, I can only advise you to really pray to God and worship Buddha when you drive in the future.

After all, our ancestors have a saying, don’t be afraid of 10,000, just be afraid of the unexpected. Moreover, the driving environment in China is very bad, and the quality of the drivers is also uneven. Anyone who has driven a car knows it well.

Sometimes, even if it is really not your fault, 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.

Peter has finished introducing his design of the car's body and structure, and now it's time to turn to the design of the car's powertrain, which reporters are most interested in.

The design of the k5's powertrain was completed by Jin Xiaoqiang, so of course the reporters found Jin Xiaoqiang regarding this issue.

Originally, everyone was not convinced that the engine of this car could achieve a compression ratio of 13:1. Many reporters even secretly speculated whether Huayang Power was bragging.

But before, when everyone saw Peter standing at the booth and personally admitting that he was one of the co-designers of this car, everyone was relieved.

Even if everyone can’t trust Huayang Dynamics, Jin Xiaoqiang, and to put it bluntly, they can’t trust Tianchao people, but Peter, as a world-renowned car design master and one of the three famous car designers in Europe, everyone can’t help but believe him, right?

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

Jin Xiaoqiang may lie, but it is impossible for Peter to lie with him. After all, Peter cannot risk the credibility he has worked hard to build for more than 20 years for Jin Xiaoqiang.

So at this time, the reporters who were originally full of doubts about the car's engine had already lost ** points, and most of them believed the data previously announced by Jin Xiaoqiang and others.

But at this time, everyone felt more sour in their hearts. How on earth did this guy do it?

Even if he is a genius, he can make the engine achieve a compression ratio of 13:1 without using a turbocharger or a supercharger. Isn't he too evil?

"Mr. Jin, can you give us a detailed introduction to the engine you designed for this car? How can it achieve the compression ratio of air and fuel without using any supercharger?

What about 13:1?”

The German reporter was reluctant to ask because he didn't want to give Jin Xiaoqiang a chance to shine, but he couldn't help it. At this time, the Japanese were the first to stand up.

The ability of the Japanese to adjust their mentality is really extraordinary. After all, making cars more fuel-efficient has always been their main goal in 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 very curious.

"Um, I have to correct this. The 13:1 compression ratio is just the data we have announced to the public. In fact, according to our theoretical design, the best compression ratio this engine can achieve is 14:1.

....."

As soon as Jin Xiaoqiang finished speaking, the same chaotic scene as before appeared in the audience.

The reporters couldn't help it anymore, so they got together and started whispering to each other. But at this time, they could talk about anything. In short, Jin Xiaoqiang's words could make these reporters lively for a while every time.

"Nani?......14:1 compression ratio? So, how did this guy do it?"

"Where's the bragging pen, right? 13:1 is already exaggerated enough. At this time, you can actually brag about such data. Can such data be achieved just by talking about it?"

"Hey! Young man, why don't you know how high the sky is and how high it is..."

"Hmph! I don't even draft a draft when I'm bragging. I'm going to ask you carefully later, how did you achieve the 14:1 compression ratio?"

"Hey, why don't you say 15:1 or wait a while, I will make you look embarrassed..."

The reporters in the audience were talking a lot after Jin Xiaoqiang finished speaking, but they also had their own hidden agendas. In short, everyone did not believe the data that Jin Xiaoqiang said!

Coupled with the previous grudge against Jin Xiaoqiang, many German reporters and Japanese reporters were gritting their teeth and waiting to make Jin Xiaoqiang look embarrassed during the questioning.

"Mr. Jin, how can you make this car achieve both a 13:1 compression ratio and a 14:1 compression ratio?"

The German reporter asked the question first. In fact, many senior German automotive media people, like Americans, prefer naturally aspirated engines.

As for technologies such as turbocharging or mechanical supercharging, it has been in recent years that Japanese cars have been widely used, especially Mitsubishi and Subaru. The extensive use of turbocharging technology has driven more consumption.

Enthusiasm for such technology.

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

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

So these German reporters are really curious about how Huayang Power achieves such a compression ratio without using a supercharger? (To be continued)
