"Actually, the issue of adjusting the compression ratio is mainly based on the grade of gasoline used by consumers. When you use gasoline with a lower grade, the compression ratio this engine can give you is 13:1, such as in

In North America you use No. 87 gasoline, but in Europe

If you are using No. 90 gasoline, but in China you are using No. 92 gasoline, then the engine’s compression ratio will be relatively low. But if you are using No. 95 gasoline in North America and No. 97 gasoline in Europe, then

, the compression ratio of this engine can reach 14:1.”

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

I originally expected him to not be able to justify himself, but I never thought that this guy would blame all the problems on the gasoline label. I feel like the design of this engine of yours is perfect, huh?

Moreover, his explanation really made many reporters feel very angry. When you said this, didn't you also say that your new model of engine can adapt to many different types of gasoline?

I need to know the data you announced before, but it is said that your car uses direct injection technology. As of now, I have not heard of that engine, especially an engine with direct injection technology.

, can adapt to various types of gasoline. Are you implying that you have made a technological breakthrough in this technology that others have not?

Showing off like this is just Taiwanese, right?

Is there any justice in this? No, everyone must squeeze some work out of him today, and we cannot let him fool around like this.

"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 engines now use turbochargers and cannot achieve such a high compression ratio.

compression ratio."

The next question from a German reporter can be said to go straight to the core of the problem. How did Huayang Dynamics achieve such a high compression ratio?

"Haha, okay, now let me 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 clearly. Anyway, it is just publicity for themselves.

"On this K5, we are equipped with our first-generation Chuangchi Blue Sky Technology 2.0L engine. On this engine, we use in-cylinder direct injection technology, and in order to achieve a better compression ratio,

I also redesigned the exhaust system of this engine. And I also made special treatment on the combustion chamber."

Jin Xiaoqiang is not afraid that these people will plagiarize these technologies after they are made public. After all, where is the patent protection bill? Moreover, even if he does not reveal the secrets of this car, there is no guarantee that others will buy one and just dismantle it.

Come and do some research.

At this time, it is better to explain these technologies openly and openly. Anyway, even if they knew it, they would not dare to blatantly plagiarize it, otherwise Huayang Dynamics could directly sue them to death.

Although some bullshit international arbitration tribunals and foreign courts may not be too fond of Chinese companies like Huayang Power, Huayang Power is cooperating with General Motors!

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

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

"First of all, I made some small changes to the exhaust pipe of this engine. Everyone knows that ordinary 4-cylinder engines generally use a 4-1 exhaust method. In this way, because of the exhaust

Because the gas stroke is relatively short, when a stroke is completed, inside the combustion chamber,

Because the exhaust stroke is short and the time is short, there is a lot of high-temperature and high-pressure exhaust gas that is not discharged for this reason. This greatly reduces the quantity and quality of fresh gas entering the combustion chamber. So I

The engine's exhaust manifold was modified to make it a 4-2-1 long-range exhaust

pattern, this lengthens the exhaust stroke, allowing the exhaust gas inside the combustion chamber to have more time after the engine completes a stroke, and can be more fully discharged out of the combustion chamber. This forms a larger gas in the combustion chamber.

space to accommodate fresh air to achieve a high compression ratio. And this

In this way, the pressure waves generated by these high-temperature and high-pressure exhaust gases will reach other cylinders and affect the cylinder's working time normally. This will minimize the possibility of knocking and at the same time allow this engine to

Better adapted to various types of gasoline on the market......"

This 4-2-1 exhaust method is originally the key to the Creation Blue Sky engine technology. At this time, Jin Xiaoqiang smiled and explained this technology to everyone.

Everyone immediately understood that this guy was not working on the air intake, but was working on the exhaust?

This guy.........as expected..........really.........shrewd enough.

In order to increase the compression ratio of automobile engines these days, everyone is thinking about how to work on the air intake, such as the turbocharger and the supercharger. These two supercharging devices, among others,

The principle is nothing more than to work hard on the air intake of the engine, so that when the engine is working, more gas can enter the combustion chamber and mix with the fuel, thereby achieving the purpose of increasing the compression ratio.

But this Jin Xiaoqiang is unique at this time. His purpose of modifying the engine exhaust manifold is actually the same, which is to increase air intake, but the method is very unique. He does not work on the air intake device, but on the exhaust

After working hard on the device, this kind of reverse thinking ability may really be possessed by only Chinese people!

Jin Xiaoqiang's thoughts and actions really surprised these reporters. It turned out that he did not use a supercharger, but only made some tricks on the exhaust pipe to achieve such an effect?

Why didn't our designers think of such a simple method before? Damn it, it seems that after returning home, we really need to let these designers brainstorm for such a simple method...

Why!

You must know that the audience in the audience at this time is not only reporters who can only use pens, but also many leaders and technical experts from other world-renowned automobile manufacturing companies. They are also interested in Huayang Power

For those interested in this high compression ratio engine.

When Huayang Dynamics started to explain the secrets of their Chuangchi Blue Sky, of course they wanted to come to the stage to see what happened!

But they never expected that the seemingly insurmountable problem could be solved by just adjusting the stroke of the exhaust pipe. This really surprised these leaders and experts.

..

There are even some people who are already yelling at the designers under their own company. They are a bunch of idiots and fools. They will fire them and kick their jobs when they get back.

In fact, they really mistakenly blamed their designers, because from the birth of the 4-cylinder engine to today, no matter how you change this engine, the exhaust pattern is basically the same. It can be said that under Jin Xiaoqiang

Before the birth of their Chuangchi Blue Sky technology, all 4-cylinder engines in the world chose the 4-1 exhaust method.

After all, this exhaust design has been used since the birth of the 4-cylinder engine, and this design is not without its benefits. It can save space, reduce the size of the engine, and allow the engine to be arranged more flexibly.

, Secondly, it can also save materials. You must know that those exhaust manifolds are all welded with large steel pipes, and their size and weight are not small.

And when everyone considered increasing the compression ratio of the engine before, they generally believed that using a supercharger was the most correct way, because in this way, the air can enter the combustion chamber to the maximum extent, and they are all working from the source.

.

No one has thought about how to manipulate the exhaust to make the exhaust gas in the combustion chamber faster and discharge more out of the combustion chamber, so no one has even considered working on the exhaust manifold.

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

Because Jin Xiaoqiang's design surprised them, but they also felt that he was cheating. After all, everyone was on the state road, but this guy took another road and reached the finish line before everyone else.

How can this prevent everyone from feeling resentful?

Such a simple method, why didn’t we think of it before?

Now, if you follow other people's designs, you will not only be laughed at by ordinary consumers, but you may also be sued. How can you keep people from getting angry with such a loss-making business?

The reporters below were talking a lot. They were obviously surprised by Jin Xiaoqiang's design and found it very fresh. However, the leaders and technical experts from various car manufacturers below were gnashing their teeth in hatred.

How did this guy's head grow? Is his brain 10% heavier than other people's? Why was he the only one who thought of such a simple method, but other designers couldn't think of it?

Jin Xiaoqiang looked at the faces of the people in the audience and felt very happy. This technology was not something he came up with. Dozens of Mazda engineers came up with this technology. It took them no less than four years to come up with it. But now

However, I directly used the attitude of borrowing and borrowing.
