Daguo Technology started from the Shanzhai system

Chapter 467 Ultra-low fuel consumption, crazy consumers!
Although they still can't understand the above performance parameters, they feel a headache and numbness from the above professional performance parameters.

But through Lin Chen's words, they already know that this high-entropy alloy is a good thing. It is a new alloy research and development direction that has only made huge breakthroughs in the past two years.

But there is still a huge question in their minds.

This question is which high-entropy alloy developed by Sugon R&D Center is stronger or weaker than other ordinary alloys, and which one is stronger or weaker than the legendary titanium alloy?

After all, they can't understand those professional performance parameters. They just want to know which one is stronger and which one is weaker, how many times the performance of the other one is, and other simple comparisons.

Facing people's curious gazes, Lin Chen paused briefly, and then went on to introduce Dawn High Entropy Alloy.

“The Dawning high-entropy alloy developed by our Dawning R&D Center is a type of high-entropy alloy that is difficult to melt.

The biggest feature of this alloy type is its high strength, high compressive strength, high plasticity, high wear resistance, high corrosion resistance and excellent low temperature resistance.

Among them, the Dawning high-entropy alloy we developed has a compressive strength as high as 2100MPa, a yield strength as high as 1201 MPa, a tensile strength of 1572 MPa, and an elongation of 23%.

The performance of this Shuguang high-entropy alloy is more than double that of many performance parameters of the steel on the US aircraft carrier!
It can be said that if it is used to build a domestic aircraft carrier, it will be a domestic aircraft carrier that can never be sunk!

Unfortunately, because the metal elements used in our Dawn high-entropy alloy include chromium and cobalt, and these two elements belong to the category of expensive rare metal elements, the material cost is naturally very high.

Although the two rare elements of chromium and cobalt do not account for a high proportion in Dawn high-entropy alloys, it is a fact that the cost of materials is high combined, and finally the ultra-high production costs and parts processing costs are added.

So let’s not talk about using it to build a domestic aircraft carrier. In fact, we can’t even build a fishing boat made of Dawning high-entropy alloy. We can only use Dawning high-entropy alloy in key places.

In this case, our pure compression ignition automobile engine is actually only used in key places such as cylinder liner, crankshaft, connecting rod, piston, piston ring, etc., while other parts use aluminum alloy, iron alloy or high-strength plastic. "

After hearing Lin Chen's words, the excitement that had just risen in the hearts of many Daxia people at the scene was instantly annihilated.

I just thought Daxia could use this high-entropy alloy to build Daxia's own domestic aircraft carrier. After all, domestic aircraft carriers are an eternal pain in the hearts of Daxia people.

But I didn't expect that the material cost, production cost and even processing cost of Shuguang high-entropy alloy were too high, and it was simply unaffordable.

This naturally caused many people's desire for a domestically produced aircraft carrier to be instantly annihilated.

But no matter what, with this Dawn high-entropy alloy, many people at the scene still believe that Daxia can achieve many breakthroughs with this Dawn high-entropy alloy.

After all, they had always heard people lamenting in the media that all problems were problems with materials.

At this time, Daxia has such a powerful high-entropy alloy, so many high-precision equipment can make great breakthroughs.

Therefore, although the dream of domestically produced aircraft carriers has been shattered, people still feel quite excited when they think that many high-precision equipment in Daxia will achieve breakthroughs in the future.

“Okay, that’s it for introducing high-entropy alloys.

Through the introduction of Sugon high-entropy alloy just now, you must already know why our Sugon pure compression ignition gasoline engine dares to claim that it can run 60 kilometers without major repairs. "

Hearing Lin Chen's words, people at the scene naturally nodded slightly to express their understanding.Although they still don't actually understand those performance parameters, it is enough to know that the performance of Dawning High Entropy Alloy is very strong.

After all, Lin Chen shouldn't lie about this and really sell cars that can only run for a few months.

Since it claims to be able to run 60 kilometers, this should be true, otherwise the reputation of Sugon Technology will be completely ruined.

In response to this, Lin Chen paused for a moment, and then continued:
"As I said just now, our pure compression ignition engine has two advantages. The first advantage is its extreme fuel economy.

The second advantage is that the overall performance is 15% of that of ordinary spark plug ignition gasoline engines, and the actual thermal efficiency can reach an astonishing 52%.

As for why the comprehensive performance and thermal efficiency are so strong, the reason is that we burn very fully and it is a homogeneous combustion.

In other words, although the amount of fuel injected is very small, because most of the mixture is used for full combustion and work, there is almost no waste, and the overall performance is naturally high.

What is worth mentioning is that because our mixture is burned very fully, the exhaust gas we emit is quite clean.

It is even cleaner than the exhaust gas purified by some ordinary gasoline engines after being purified by a three-way catalytic converter.

Therefore, some countries with less stringent emission requirements can simply abandon the expensive thing of three-way catalytic converters, which can directly save hundreds of yuan in the cost of three-way catalytic converters. "

After hearing Lin Chen's introduction, many people at the scene brightened up, and their expectations for Sugon's pure compression ignition gasoline engine are growing.

However, Lin Chen had not finished the introduction at this time. Lin Chen continued to introduce:
"As for our other advantage of extreme fuel economy, how much can it save? In theory, we can achieve 3.2 liters per [-] kilometers!
Of course, because Sugon Motors puts user safety and comfort first as its design philosophy, we do not cut corners like Japanese cars.

The materials used in the chassis, frame, casing, interior decoration, etc. are relatively sufficient. With the same wheelbase width and length, the weight of our cars is about 40% heavier than the average car from the island country.

So in fact, if you often drive on national highways or even highways, you can theoretically only achieve a fuel consumption of 3.6 to 4.1 liters per [-] kilometers! "

Hearing Lin Chen's words, people at the scene instantly showed expressions of surprise.

They had heard Lin Chen repeat several times before that pure compression ignition gasoline engines save fuel, and they were already prepared.

But they didn't expect that the fuel saving could be to such an extent, which completely exceeded their psychological expectations.

Because this is 3.6 to 4.1 liters per [-] kilometers in actual use. Such low fuel consumption is simply unimaginable.

At this time, they finally understood why Lin Chen said that this pure compression ignition gasoline engine was extremely fuel-efficient.

Because although the fuel consumption of many cars on the market is publicly listed as 6 liters, 7 liters and 8 liters per [-] kilometers, in fact everyone understands it. In actual use, people simply cannot achieve that level of fuel consumption.

Because the car cannot always be in ideal operating condition, he will be stuck in traffic, he will encounter intersections, he will encounter moving roadblocks, and he will encounter such bad roads that he will not dare to drive fast.

Therefore, the average actual fuel consumption of cars in this era is between eight liters or even more than ten liters per [-] kilometers.
