All engines on this earth, according to the mechanical arrangement, can be divided into horizontally opposed engines and in-line engines, which are distinguished according to the distribution of cylinders!

At the same time, according to the difference in engine work, it can be divided into two categories, one is the reciprocating engine, which is the most common piston engine, and the horizontally opposed engine of Porsche and Subaru is also of this type, which is to link the cylinder piston with the crankshaft connecting rod, and push the piston to do reciprocating motion with the combustion expansion of the cylinder.

The other is the rotary engine, which represents Mazda's rotary engine! This engine has no pistons, no connecting rods, but a triangular rotor in the cylinder, and after combustion and expansion, the gas will push the triangular rotor to rotate endlessly, so as to generate power!

In contrast, gyratory engines are more efficient than piston reciprocating engines, can do more work with a smaller cylinder volume, provide higher speeds, and output more power.

At the same time, there is only one rotor in the cylinder of the rotary engine, and there are not so many parts such as pistons, crankshafts, connecting rods and other parts of the piston engine, so the rotary engine is lighter, and it is also easier to maintain, and stable, after all, there are less than ten or twenty parts!

However, this different cylinder structure makes the cylinder wear more and more likely to be damaged, and it is actually inconvenient to maintain different structures!

Because, the first rotary engine was successfully invented by the Germans in the fifties, and it was only announced in the sixties. At that time, the piston engine has appeared for more than half a century, Europe and the United States and other parts of the world have long been dominated by the piston engine market, the upstream and downstream industrial chain has been perfected, there is no chance to survive a new engine!

Therefore, although the German company had already succeeded in inventing at that time, no one cared about it for a while. In the end, he cooperated with Citroen to build a rotary engine vehicle, but it failed without luck.

Mazda then bought the engine technology from this company and worked on it on its own, eventually making the transition from lab to commercial, and then launched the RX7 sports car, which was successfully launched in the United States with some success.

However, failure is still doomed!

This engine itself is an outlier in the mainstream market, and the upstream and downstream industry chains have no supporting facilities at all. Moreover, the life of the engine is very short, and the engine will almost be scrapped after running two or three hundred thousand kilometers, and the fuel consumption is very high and the pollution is serious.

Therefore, when the RX8 was listed at that time, it only had a displacement of 1.3, but when Japan, Europe and the United States and other structures charged a displacement tax on this model, it was multiplied by two, that is, doubled, and the tax was collected according to the 2.6 displacement!

However, even with all these shortcomings, this car is still an epoch-making representative in the minds of many people, because its engine is different from all other engines.

ON TOP OF THAT, THE RX8 SPORTS CAR LAUNCHED TEN YEARS AGO WAS ONLY A 1.3-LITER NATURALLY ASPIRATED TWIN-CYLINDER ENGINE, BUT IT COULD MAKE 151 K, 205 PS OF HORSEPOWER, AND 211 NM OF TORQUE!

But Mazda still has not been able to solve its drawbacks, that is, high fuel consumption, almost twice that of the piston engine, and the wear and tear of the triangle rotor still cannot be solved, at most about 300,000 kilometers of life, it will be scrapped, and the piston engine can generally be driven by several major car companies The engine can be driven seven or eight hundred thousand, or even millions of kilometers There is no major problem.

Therefore, Mazda's rotary engine series has been discontinued after all, although recently there has been news that Mazda is preparing to release a new rotary engine, but the market is not very expected.

Because, after all, the rotary engine is a niche, which is liked by some enthusiasts, not for the masses.

And only Mazda itself is playing, and no other car companies are involved. Not to mention that Mazda can only rank three or four among Japanese car companies, even if it is the world's first car company like Toyota, it does not have the ability to carry the upstream and downstream industrial chain of a new engine by itself, and compete with all other car companies in the industrial chain that has been perfect for hundreds of years!

Therefore, Mazda's rotary engine is just a toy for niche car enthusiasts after all!

Almost everyone in the automotive industry does not believe that this new engine has the potential to be commercialized successfully, nor is it possible to challenge traditional piston reciprocating engines!

But.

Wang Jun doesn't think so.

He found another non-piston engine from the physics textbooks of the alien Correns Empire, similar to Mazda's rotary engine, but with a completely different difference, the structure is a little more complicated, but it is still simpler and lighter than the piston engine!

Wang Jun is now building this kind of rudimentary two-cylinder engine in the laboratory!

"Sir, did you really design this yourself?"

Richard served as Wang Jun's assistant and participated in the entire design and manufacturing process of the engine, starting from scratch, he didn't know what he was doing at first, and after he understood, he didn't know what Wang Jun wanted to do.

Mazda's rotary engine, Richard naturally knows and understands, but he didn't delve too much into research, because he, like almost all people in the automotive industry, does not think that this engine has more potential to be tapped.

One is that the piston engine industry chain has been formed for more than 100 years.

Another important reason is fuel consumption and life.

Because, now that new energy vehicles have gradually begun to develop, piston engines with low fuel consumption will be gradually eliminated, then this scary rotary engine with high fuel consumption will be the first to be eliminated.

Therefore, Richard did not understand why Wang Jun, who knew more about cars and engines, would make such a machine similar to a rotary engine.

Wang Jun looked extremely firm and confident, and touched this product from alien industrial design!

He modified it slightly according to his own understanding, because the fuel and air on the earth are not the same as the Correns Empire after all.

However, he still clearly remembers that this kind of engine in the Corens Empire is only equipped with high-end sports cars, and is called the last crystallization of the mechanical automobile industry.

Because, after the interview with this engine, the Collens Empire has entered the interstellar age, various advanced technologies such as anti-gravity have gradually matured, suspension cars have gradually become the mainstream, and fuel mechanical cars have gradually been eliminated, and they are only commonly used on relatively backward planets, and some mechanical enthusiasts insist on using them!

Compared with the earth's Mazda rotary engine, Wang Jun's engine has higher requirements for materials, and at the same time, the power of the explosion is also stronger, and because of the more advanced design and the reason that the materials are more advanced, the shortcomings in life have also been compensated, and it should not be a problem to run millions of kilometers!

However, there is still a problem that Mazda has been facing!

That is, industrialization is too difficult!

After all, this kind of engine is a niche, a toy for enthusiasts, and will not become mainstream!

However, Wang Jun never thought of facing the public directly.

"Yes, I came up with it after a long time. ”

Wang Jun said this proudly, because there are indeed a lot of his design ideas, adding his understanding of the physics knowledge of the Correns Empire, as well as the application of some new materials!

This kind of alloy material can only be produced by the production line he designed, even if Zhang Shaoyang's production line improved by him cannot be directly produced, it can only produce semi-finished products, and it must be processed by him once, add some other metals, increase density, reduce weight, and then it can be formed, and then it can be used to manufacture this kind of engine!

Richard shook his head slightly and said, "Sir, I believe that this engine will have excellent performance, but I am not optimistic about its prospects!"

Wang Jun smiled: "It's okay, this is not our main game!"

Looking at the door of the laboratory, Wang Jun pressed the remote control to open them, and let Peng Youhua and Liao Gong from FAW come in.

Peng Youhua and Liao Gong are both senior automotive engineers who understand technology, so as soon as they came in, they walked directly to this novel engine, which looks similar to Mazda's rotary engine, but is not the same.

"Professor Wang, you designed this?"

Peng Youhua calls Wang Jun with an honorific title like you, and he is no longer as casual as before, and he doesn't dare to be condescending.

Wang Jun has already shown an absolute genius in the field of automobiles, as well as an absolute genius in the fields of physics and mathematics, such a top talent, even in front of national leaders, will be courteous, let alone at his level.

Liao Gong stretched out his hand, gently stroked the engine, carefully felt the different structure, his eyes seemed to eat the engine, and said in admiration: "Such a delicate design, it is simply ingenious, it's a pity, it's a pity, it's a pity......"

Peng Youhua and the others looked at Liao Gong, not knowing what he meant by pity.

Engineer Liao let out a sigh of relief, looked at Wang Jun's eyes full of regret, and said helplessly: "Although I haven't tried it yet, with my major, I can see that the excellent mechanical structure of this engine is definitely the most advanced in the world." However, he was born at the wrong time, and the entire internal combustion engine industry is almost a sunset industry, not to mention this kind of niche internal combustion engine, if we can build it 30 years ago, with the blank in the domestic automobile field at that time, perhaps with the support of the whole country, we can develop a complete industry!"

"Now, maybe I can only sell it as a toy to some special lovers......"

Recently, several European countries signed an agreement to no longer manufacture and sell vehicles with internal combustion engines by 2050, and China has signed a similar agreement!

Therefore, it is not an exaggeration to say that the internal combustion engine is a sunset industry, but there are at least a few decades of development and transition time, which is enough for several major car companies in the world and the oil industry to complete a new industrial transformation.

However, for this new niche internal combustion engine, there is almost no development opportunity at all.

The entire internal combustion engine industry is dying, who cares about your niche engine?

If it was 30 years ago, when China's automobile industry was just starting out and was still begging the public, if there was such an opportunity, perhaps it would do its best to develop a new field of internal combustion engines, improve the upstream and downstream industrial chain with the strength of the whole country, and create a world-class car company.

But now, it's too late!

So!

Liao Gong, like Richard, is not optimistic about the future of this engine at all.

Wang Jun's eyes flickered, thinking in his heart, and said lightly: "I naturally have my ideas, even if the mainstream market is not acceptable, I will continue to develop related products, as the first product of our Super Heavy Industries." We are super heavy industry, that is, to make different products, is to be a market disruptor!"

"The same is true for the cooperation with you Pentium, our purpose is to open up the market for domestic commercial vehicles!"

Peng Youhua nodded and said, "Yes, we all have to be spoilers." Now the world's major car companies think that they have carved up the market, but we have to say no! Professor Wang, I support you on this point. When the time comes, if you need help and support, as long as we can do it, we will never shirk!"

Wang Jun smiled: "Okay, I'll open my mouth when the time comes, now, I'll first do a test for this brand new engine I designed myself, and see what the parameters are!"

"Okay, I'm here to help!"

"I'll do it too!"

Liao Gong and Peng Youhua hurriedly came over to help with the test.

Richard was naturally not slacking off, and the other Peng Huabing and Hu Fei also hurriedly walked in, watching with great curiosity!

The horizontally opposed engine developed by Wang Jun himself last time has proven its powerful performance, and it can almost be said to be the strongest mass production 2.0 engine!

This time, Wang Jun has developed a different engine, so what surprises will it bring?

Enthusiasts of playing cars, there is almost a perverted pursuit of the parameters of the car engine, speed, power, horsepower, torque, drive and so on!

Wang Jun personally slowly added the ordinary No. 95 gasoline on the earth to the mailbox for fuel supply, and then turned on the oil supply and ignited the engine!

Buzz Buzz......

Woo Woo ......

The sound of this engine instantly sounded, it was a completely different sound from a piston engine, but it was extremely pleasant, and it sounded like a powerful look, like a high-powered sports car blowing up the street on the street.

However, the sound is not very loud, but it is very stable, very regular, and very powerful!

WhewW......

The rev increases quickly!

This type of engine is characterized by higher speed and more power!

However, this crazy speed still surprised everyone!

Almost, after a few seconds, the revs are above the corner......

The gears that output power rotate wildly, and the naked eye can feel the strong and surging power!

Richard hurriedly linked the test tools one after another!

Moment!

The parameters that have been tested appear on the instruments one by one!

Except for Wang Jun, who had expected it a long time ago, everyone else had a pair of eyes full of disbelief!

Is this a 1.2L twin-cylinder engine?

And it's still naturally aspirated, and the pressurization equipment has not been installed?

Fake, right......

Everyone couldn't believe it.
