reborn industrial empire

"First of all, our second-generation ebst engine uses our second-generation twin-scroll single-turbo turbocharger. As for the technical parameters of this turbocharger, I think you are attending BMW's new car launch conference.

I have already understood everything before, so I won’t give a detailed introduction.”

Jin Xiaoqiang’s words made the reporters in the audience burst into laughter. Obviously he was reminding everyone that despite BMW’s roar, we still provide their turbochargers.

This point speaks to the preferences of us Chinese people. We Chinese people generally like to be low-key and don’t like to be too public, so we often leave a humble impression on others.

But from the perspective of modern business philosophy, this is simply a silly old hat. If you have good things, of course you have to publicize them. Now we are no longer in the era when the smell of wine is not afraid of the dark alleys.

Moreover, this second-generation turbocharger was indeed developed by Huayang Power, and is now used by BMW. If I talk about it again at this time, it is easy for people to have a better impression of this turbocharger.

, after all, the BMW brand is there, they won’t use rubbish.

Since they use this turbocharger, it is enough to prove that this turbocharger does have its unique features.

“The second thing I want to introduce is the changes we have made in some details of the engine this time. The first thing I want to introduce is the electronic valve lift control technology we added to the second-generation ebst engine.

The addition makes the control of our variable valve timing technology more precise, thereby maximizing the torque output of the car engine."

In fact, this electronic valve lift technology has already existed. The best one in the early years was Japan's Honda. At that time, they combined this electronic valve lift technology with variable valve timing technology.

, and then it became their classic vte technology, which has been used to this day and remains popular for a long time.

Later, big companies such as BMW, Audi, and Mercedes-Benz also developed this technology, used it in their engines, and promoted the combination of the two technologies. However, each of them has its own version of this technology.

Law

Later, the only one who really took out this technology and chewed it up again, and achieved good results, was BMW.

It is precisely because of their precise data analysis and computer control that electronic valve lift technology becomes particularly important, especially when combined with variable valve timing technology, it becomes even more complementary.

It was BMW that instilled this concept in everyone, that is, everyone used variable valve timing technology in the past, just to better control the opening and closing time of the valve, and to achieve better air intake and exhaust purposes.

So as to achieve the ultimate goal of fuel saving, but now with the support of electronic valve lift technology, this variable valve timing technology can not only save fuel better, but also control the torque output more accurately, making the torque output variable.

to be wider, so as to achieve the purpose of making the car more powerful.

In this way, people separated the electronic valve lift technology from the variable valve timing technology, and divided the two systems into two, making them more subdivided.

And now Jin Xiaoqiang has divided this technology from their variable valve timing technology, which shows that Huayang Power has made great progress in vehicle electronic control, and they have also made great progress in the segmentation of engine work.

made a breakthrough

"With the intervention of this system, our on-board computer will more effectively distinguish the three most important areas for car performance: the best idle speed and lean combustion areas, the best fuel consumption and exhaust control areas, and the best torque control areas.

important area"

As soon as the reporters in the audience heard Jin Xiaoqiang talk about these key points, they knew that he was not lying. It seemed that they had really mastered the key to controlling the electronic valve lift just like BMW.

"How's his performance?"

A German reporter asked reluctantly, you know, this used to be BMW's unique skill.

"The intake valve lift can be continuously changed from 0.3 mm to 9.9 mm"

Isn’t this data already comparable to BMW? You must know that there are not many companies that can control the electronic valve lift so accurately. Apart from BMW, there is really no other company that can do it?

Although they were a little reluctant, the Germans still accepted the fact. Fortunately, they did not surpass BMW. The Japanese reporter on the other side had red eyes. Honda had been leading in this field for so many years. Who would have thought that it would be overtaken by Huayang Power in one day?

I fell to the ground. I'm really unwilling.

"In addition, in order to improve driving comfort, we have also developed a set of piston pin offset and crankshaft offset technologies for this set of heart engines. The main purpose of developing this set is to reduce noise. Everyone knows that when the engine is working

When the piston reaches top dead center

When it starts to move downward, due to the gap between the piston and the cylinder wall, the piston will move from the right to the left and produce a certain impact sound. This phenomenon is also called cylinder knocking. In order to prevent the occurrence of cylinder knocking,

Usually when designing the position of the piston pin, it is pushed towards the main part of the piston.

One side of the surface deviates by a maximum of about 2 mm. When the piston changes direction, the piston will tilt in the cylinder, thereby reversing in advance and reducing the cylinder knocking sound. The offset of this piston pin is visible to the naked eye.

It's almost invisible but it wastes a certain amount of power and also

This produces too much waste. The piston pin we used this time is a negative offset design, and the crankshaft will also adopt a certain offset design, which will greatly reduce cylinder knocking during work.

sound, and makes a considerable contribution to the engine’s fuel economy.”

Jin Xiaoqiang’s explanation on the stage made the German reporters in the audience even more depressed. You must know that the piston pin offset and crankshaft offset are used to reduce the cylinder knocking sound, but the Germans have always been proud of it. Although this technology is not suitable for

The performance of the engine may not be of any benefit, but it is the highest expression of German finishing technology, and it is also the reason why BMW engines are praised for their luxury. It is reflected in such small details. Our noise control is good.

But now it seems that Huayang Power also has such finishing capabilities, and it is impossible to say that it copied it, because BMW used a positive-bias design before, while Huayang Power uses a negative-bias design.

bias

No wonder Jin Xiaoqiang wants to classify this car as a luxury high-end car to compete with Mercedes-Benz and BMW. It seems that in terms of technical details, he does have the capital to compete with BMW and Mercedes-Benz.

“The integrated design of the main bearing cover and cylinder block reduces the number of parts as much as possible and improves the strength of the engine block. The most critical thing is the arc wire spraying technology we use on the inside of the cylinder wall of this engine.

"

When Jin Xiaoqiang said this, the reporters in the audience also pricked up their ears. Everyone has heard of this arc wire spraying technology before, but this technology is more difficult and more expensive, so it is really big

There are not many large-scale applications. Now that Huayang Dynamics has tasted crabs, of course everyone wants to know how they are doing.

In the past, Audi and BMW both launched so-called pure aluminum engines. In fact, they were just a gimmick for external publicity. Everyone knew that there were no pure aluminum engines at that time because the cylinder block was not good enough.

You can use aluminum alloy as a cylinder head, but it is absolutely not possible as a cylinder, because the strength of aluminum alloy is really not enough.

Moreover, the materials used in the piston are generally steel products. If aluminum alloy materials are used to make the cylinder block, then the friction coefficient will be different, the temperature cannot be adjusted, and finally a series of problems such as oil burning and even cylinder pulling will occur.

This is the main reason why early Audis were prone to cylinder pull.

Later, Audi used a method of adding a layer of steel cylinder liner to the inner wall of the cylinder to solve the problem, and companies such as BMW also followed suit. This became the earliest so-called pure aluminum alloy engine.

However, using a cylinder liner will still increase the weight of the engine, which is not conducive to reducing the weight of the car body to save fuel. Therefore, many people are thinking about new methods, and arc spraying is a good method.

"We use high-temperature arcs to dissolve iron, and use high-pressure air to evenly spray the iron solution onto the inner wall of the aluminum alloy cylinder. Only a thin layer is needed, which is more expensive than adding a cylinder liner.

Saving about 80% of the weight has greatly improved the engine's fuel-saving performance and thermal conductivity, and the cost can also be effectively controlled."

This is the benefit of new technology. You must know that if steel cylinder liners are used, not only the production requirements are high, but also the processing accuracy is also very high. Therefore, the overall cost is not much lower than that of arc spraying. However, arc spraying is used

Technology can both reduce costs and improve efficiency. Why not?

The reporters in the audience listened with fascination. Many people began to lament about this engine. Although Jin Xiaoqiang has not announced the final data of this engine, everyone has already noticed these details.

This is definitely not a simple item. It can definitely be called a high-end luxury product. It can definitely compete with Mercedes-Benz and BMW.

With these detailed technical support, the real competitors of the BMW 7 Series and Mercedes-Benz S600 series can be said to have really arrived this time, and you must know that Jin Xiaoqiang has not yet announced the performance data of this engine.

Jin Xiaoqiang has always been a master in this regard.

And despite the inconspicuous details and technologies he mentioned in front of him, if these detailed technologies are integrated together, then the ultimate data of this engine can definitely reach a big level (to be continued, you are welcome to come)
