After all, the prospect of pure compression-ignition gasoline engines was quite wonderful, but we tried it countless times.

After spending tens of millions of dollars and nearly a year, this path was finally proved wrong.

Because we found that with the current level of human metal material technology, it is simply impossible to achieve the long-term operation of pure compression-ignition gasoline engines.

With the current technical level of human metal materials, pure compression-ignition gasoline engines will naturally run no problem in the short term.

But in fact, because the compression ratio required for a pure compression-ignition gasoline engine is too high, it is a disaster in the long run.

Our pure compression-ignition gasoline engines actually ran for less than 100 hours without the use of expensive top-of-the-line metal alloys.

Subsequently, in the random inspection, it was found that there was a slight deformation of the core accessories such as the piston, connecting rod, and crankshaft!

Although we can increase the volume of pistons, connecting rods, and crankshafts to improve compressive resistance, buckling resistance, etc.

However, because the piston volume increases, the final compression ratio decreases, and the engine volume will become larger and cannot fit into the car.

So we tried and experimented in many ways, and in the end they all failed.

At the last time, we finally used a more expensive top-of-the-line metal, but it succeeded in extending the service life a lot.

However, because the price of materials is too high, it is not affordable for ordinary cars at all, which is contrary to the purpose of low production cost and fuel saving.

And although the life is extended, it is still not enough to meet the minimum demand of 150,000 kilometers of a car without major repairs, and it can only last for 3 months at most.

So we spent tens of millions of dollars on Fengtian Motors and finally failed, and the only best but most expensive finished product only lasted for 3 months.

With your backward metal material technology in Daxia, at this time you claim to have completed the development of a pure compression-ignition gasoline engine, which is simply a joke. ”

Hearing the words of Fengtian Barrier Man, the people at the scene finally showed a sudden realization expression.

Although there are still many technical terms that they don't understand, they also know that it is really difficult to develop pure compression-ignition gasoline engines.

A pure compression-ignition gasoline engine technology that even the R&D team of Fengtian Automobile Company couldn't figure out, and finally gave up!

However, at this time, Lin Chen did not show the panic of being exposed to the secret, but clapped his hands, and then praised with a smile:

"Mr. Fengtian is worthy of being a man who can sit in the position of vice president of Fengtian, not to mention his professional knowledge, and he is also familiar with the internal situation of the company."

Hearing Lin Chen's uncharacteristically praising himself, the uneasiness in Fengtian's heart became bigger and bigger at this time, and he felt that something seemed to be wrong.

However, before the uneasiness in Fengtian's heart continued to expand, Lin Chen had already made a move at this time.

I saw Lin Chen smile and say in the midst of people's incomprehensible gaze:

"What Mr. Tsukasuo Tsunoda is talking about is indeed a huge problem with pure compression-ignition engines, and it can even be said that the problem has hindered us for quite some time.

But in the end, we overcame it all one by one, as for how to overcome the problem of substandard metal material performance.

The solution is to develop a new alloy material called Dawning high-entropy alloy.

The use of this Sugon high-entropy alloy can make our pure compression-ignition gasoline engine not only have super compressive and yield resistance, but also other aspects of comprehensive performance and even life have ushered in a qualitative leap.

According to our test statistics, if the 5000~7500 km regulation is maintained, the qualified regular engine oil is replaced on time.

Theoretically, our pure compression-ignition gasoline engine can work normally for 600,000 kilometers, so our pure compression-ignition gasoline engine can be claimed to be 600,000 kilometers without overhaul! ”

"Wow!"

Hearing Lin Chen's words, the scene was instantly in an uproar.

After hearing Lin Chen's words, people instantly fell into an uproar and shock.

After all, they had learned about the difficulties of pure compression-ignition gasoline engines through the words of Fengtian Barrier, vice president of Fengtian Automobile.

After all, with the technical strength of Fengtian Automobile, without using expensive top-level metal alloys, it can only produce a pure compression-ignition gasoline engine that runs for no more than 100 hours.

In the case of the use of top-grade metal alloys, the longest is only four months, which simply does not meet the standard of long-term use.

At this time, Lin Chen claimed that the pure compression-ignition gasoline engine developed by the Shuguang R&D Center could operate normally for 600,000 kilometers, claiming that there was no overhaul for 600,000 kilometers.

In such a situation, how can the people at the scene not show shocked expressions?

"Okay, since you don't believe it, let me announce the performance parameters of the core material of the Dawning compression ignition engine, the Dawning high-entropy alloy."

As Lin Chen spoke, the performance parameters of the dawning high-entropy alloy appeared on the projection screen behind him.

And people naturally show a stunned expression in the face of these professional performance parameters, because the above performance parameters can't be understood at all.

They can barely understand the hardness of the metal material on it, and know what kind of concept it represents.

But then the strength, toughness, fatigue performance, tensile strength, yield strength, fracture resistance, corrosion resistance, oxidation resistance and other parameters make people confused.

However, the vast majority of the audience at the scene does not understand does not mean that all of them do not understand, at this time there are not a few people who understand those performance parameters, including Fengtian handicap man.

"How is this possible!"

Seeing the terrifying performance parameters of the dawning high-entropy alloy, Feng Tian Barrier Man couldn't suppress the shock in his heart at all.

And this shocking sound was naturally transmitted to the entire press conference through the microphone still in his hand, which made many people at the scene show curious eyes.

Could it be that the performance of the Aurora high-entropy alloy is very powerful?

Otherwise, why would the dignified Fengtian Automobile Vice President Fengtian Barrier Man be so out of shape?

I have to say that at this time, even if they can't understand how strong the performance parameters of the high-entropy alloy are, after seeing Fengtian Barrier Man so out of shape.

They already knew that the Dawning high-entropy alloy developed by the Dawning R&D Center must be very powerful and terrifying.

"As you can see, this is the high-entropy alloy developed by our Sugon Technology, which is a new upstart in the current material industry.

Although high-entropy alloys have a history of decades since the birth of the earliest basic theory, it was only in the 90s of the last century that they really took it seriously.

Subsequently, it was not until 2004 that Professor Wanjima Ye proposed a new design model of multi-component high-entropy alloys, which finally officially opened the era of large-scale research and development of high-entropy alloys.

Among them, high-entropy alloy is considered by the materials industry to be one of the three major breakthroughs in the alloy industry in recent decades, which shows how significant the birth of high-entropy alloy is. ”

Hearing Lin Chen's words, the people at the scene nodded lightly as if they didn't understand. (End of chapter)
