"In fact, the adjustment of the compression ratio is mainly aimed at the label of the gasoline used by consumers. When you use a relatively low gasoline grade, the compression ratio that this engine can bring you is 13:1, for example, in North America you use 87 gasoline, in Europe you use 90 gasoline, in the Celestial Empire you use 92 gasoline, then the compression ratio of the engine is relatively low. But if you're using No. 95 gasoline in North America and No. 97 gasoline in Europe, the compression ratio of this engine can be 14:1. ”

Jin Xiaoqiang smiled and explained to the reporters in the audience, and as soon as his explanation came out, the reporters in the audience were even more in an uproar.

I expected him to not be able to justify himself, but I thought that this kid actually pushed the problem on the label of other people's gasoline, and I feel that your engine design is flawless, huh?

And when he explained this, it really made many reporters feel very angry, when you say this, don't you say that your new model engine can adapt to many different types of gasoline?

You have to know the data you have published before, but it is said that your car uses in-cylinder direct injection technology, as far as it is concerned, I have not heard of that engine, especially the engine with in-cylinder direct injection technology, which can adapt to various types of gasoline, are you implying that you have made a technological breakthrough in this technology that others do not have?

You show off like this, and it's also Taiwanese red fruit, right?

Is there any reason for this? No, today, everyone has to squeeze some work out of him, and we can't let him just fool around.

"Then Mr. Jin, what we are more curious about is how your engine can achieve such a high compression ratio, you must know that many turbocharged engines cannot achieve such a high compression ratio even if they use turbocharging."

The next question from a German reporter can be said to be straight to the core of the real problem, how did you Huayang Power do it, such a high compression ratio.

"Hehe, okay, now I'm going to explain to you the uniqueness of our engine design."

Jin Xiaoqiang laughed, and then said to the reporters in the audience, since they want to know so much, let them understand it, anyway, it's just to make a propaganda for themselves.

"On this K5 we are equipped with our first generation of SKYACTIV 2.0L engine, in this engine, we have adopted direct injection technology, and in order to achieve a better compression ratio, I have also redesigned the exhaust system of this engine, and I have also done special treatment in the combustion chamber."

Jin Xiaoqiang is not afraid that after these technologies are made public, these people will plagiarize, after all, where is the patent protection bill, and even if he doesn't announce the mystery of this car, he can't guarantee that people will buy one back and directly disassemble it for research.

At this time, it is better to simply be generous and explain these technologies, anyway, even if they know, they don't dare to plagiarize blatantly, otherwise Huayang Power can directly sue them to death.

Although the international bullshit arbitration tribunal and foreign courts may not be very welcome to a Celestial Empire enterprise like Huayang Power, Huayang Power is cooperating with GM!

Even if those foreign courts and judges don't sell the face of Huayang Power, they have to sell face to General Motors, right?

GM is very difficult to deal with, but the US government behind him is even more difficult!

"First of all, I made some small changes to the exhaust pipe of this engine, we all know that ordinary 4-cylinder engines generally use the 4-1 exhaust method, and in this way, because the exhaust stroke is relatively short, often after the completion of a stroke, in the interior of the combustion chamber, because the exhaust stroke is short, the time is also short, so there are a lot of high temperature and high pressure exhaust gases, will not be discharged for such reasons. This greatly reduces the quantity and quality of fresh gas entering the combustion chamber, so I changed the exhaust manifold of the engine to make it a 4-2-1 long-range exhaust pattern, which lengthens the exhaust stroke, so that after the engine has done a stroke, the exhaust gas inside the combustion chamber has more time to be discharged from the combustion chamber more fully. This creates a larger space in the combustion chamber to accommodate fresh air and achieve a high compression ratio. And in this way, the air pressure wave generated by these high-temperature and high-pressure exhaust gases will reach other cylinders, and the working time of the cylinder will be normal, so as to minimize the possibility of detonation, and at the same time, it can also make this engine better adapt to various types of gasoline ...... on the market"...,

This 4-2-1 exhaust method was originally the key to the creation of blue sky engine technology, at this time Jin Xiaoqiang smiled and explained this technology to everyone.

Everyone immediately understood, this guy didn't do anything about air intake, but on exhaust?

This guy ...... Really...... Really...... Shrewd enough.

In order to increase the compression ratio of the automobile engine in these years, the big guys are thinking about how to work the air intake, such as the turbocharger and the mechanical supercharger, these two superchargers, the principle of which is nothing more than to work the intake of the engine, so that when the engine is working, more gas can enter the combustion chamber and mix with the fuel, so as to achieve the purpose of improving the compression ratio.

But this Jin Xiaoqiang is unique at this time, his purpose of changing the engine exhaust manifold, in fact, is the same, is to increase the air intake, but the method is very unique, he is not working on the air intake device, but on the exhaust device, such a reverse thinking ability, maybe only the Celestial Empire people have!

Jin Xiaoqiang's ideas and practices really surprised these reporters, it turned out that people didn't use superchargers, but just did some tricks and feet on the exhaust pipe, which can achieve such an effect?

How come our designers didn't think of such a simple way before? Hell, it seems that after going back, I really have to let these designers brainstorm for a while, such a simple way...... Ay!

You must know that at this time, the audience is full of not only those reporters who can only play with their pens, but also many leaders and technical experts from other world-renowned automobile manufacturers, who are also interested in this high-compression ratio engine of Huayang Power.

When Huayang Power began to explain the mystery of their SKYACTIV, of course they wanted to come to the audience to get a glimpse!

But they never thought that the seemingly incomparable problem was solved by just adjusting the itinerary of the exhaust pipe, which really surprised these leaders and experts......

There are even some people who are already scolding the designers under their own company for being a bunch of idiots, stupid, who are going to fry their squid and kick their jobs when they go back.

In fact, they really blame their group of designers, because from the birth of the 4-cylinder engine to today, no matter how you change the engine, but the exhaust pattern is basically the same, it can be said that before the birth of Jin Xiaoqiang's Skyactiv blue sky technology, all the 4-cylinder engines in the world are selected 4-1 exhaust mode.

After all, such an exhaust design has been used since the birth of the 4-cylinder engine, and this design is not without benefits, one can save space, reduce the volume of the engine, so that the engine can be more flexible layout, and the other is also to save materials, you must know that those exhaust manifolds are welded with large steel pipes, and the volume and weight are not small.

Moreover, when everyone considered increasing the compression ratio of the engine, it was generally believed that using a supercharger was the most correct way, because in this way, the air could enter the combustion chamber to the greatest extent, and it was all done from the source.

No one has thought about how to do it from the exhaust side, so that the exhaust gas in the combustion chamber is faster and more excluded from the combustion chamber, so no one thinks about working on the exhaust manifold. …,

So when many people hear that Jin Xiaoqiang used such a simple method to make the engine achieve such a high compression ratio, they will feel both surprised and angry.

Because of Jin Xiaoqiang's design, they felt very surprised, but they felt as if he was cheating, after all, everyone was on the state road, but this guy took a different path, and he reached the end before everyone, how can this make everyone not feel resentful?

Why didn't we think of such a simple way before?

Now, if you follow the design of others, you will not only be ridiculed by ordinary consumers, but I am afraid that you will have to suffer lawsuits.

The reporters below were discussing, obviously surprised by Jin Xiaoqiang's design, and felt very fresh, while the leaders and technical experts from various automobile manufacturers below were gritting their teeth with hatred at this time.

What the hell does this guy's head look like? Could it be that his brain is ten percent heavier than others? Why is it that only he thinks of such a simple way, but other designers can't think of it?

Jin Xiaoqiang looked at the faces of the people in the audience, and his heart was very refreshing, this technology was not something he came up with, this technology was developed by dozens of engineers from Mazda, and it took no less than four years to come up with it, but now it is directly used by himself to bring it to the ...... ）
