When it comes to horizontally opposed engines, all those who know cars will shout out two world-famous brands for the first time!

The first is Porsche, which is known as the highest level of German mechanical craftsmanship, and is called a mechanical work of art!

The second is Subaru, which was once synonymous with Japanese off-road vehicles!

Even, many people divide the world's automobile groups into two camps, the first is Porsche and Subaru, and the second is all other automobile groups!

This division is based on the different structures of the engine. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

Perhaps some Mazda fans will say that the so-called Skyactiv technology created by Mazda is also unique, but in fact, Mazda's Skyactiv is not a unique engine technology, but a general term for a whole series of comprehensive technologies, which is a technology research and development for the purpose of reducing fuel consumption, improving combustion efficiency, improving power output and reducing emissions!

It's not just minor changes to the engine, but also to the gearbox, the drivetrain!

And Mazda's engine is basically a traditional cylinder and piston layout, so it also belongs to the camp other than Porsche and Subaru!

As a first-class expert in professional modification of Porsche, Richard has hundreds of Porsche engines in his hands, so he naturally knows these things well.

The horizontally opposed engine, as you can see from the name, is an engine structure in which the engine pistons are evenly distributed on both sides of the cylinder, and the cylinder is horizontally transverse, and the pistons are on both sides of the cylinder!

The advantage of this is that it can improve the combustion efficiency, reduce the engine volume, reduce the center of gravity of the engine, reduce the vibration during the combustion of the engine, and the evenly distributed piston on both sides can cancel out part of the vibration force of each other.

The benefits are many!

This is one of the most important reasons why Porsche sports cars are called mechanical works of art, because Porsche's engines are different from all other sports car engines, with more complex structures, more precise craftsmanship and more powerful power output!

But at the same time, there are good and bad.

Horizontally opposed engines also have shortcomings that cannot be concealed, the most important of which is that the mechanical structure layout is extremely complex, which leads to high manufacturing costs and higher requirements for technology. And because the cylinder is horizontal, because of gravity, the lubricating oil in it will not flow smoothly to the entire cylinder block!

Also, because the engine is horizontally opposed, the engine is very wide, which is not conducive to the overall layout of the car!

Therefore, this makes all manufacturers in the world except Subaru and Porsche, even if they know that the horizontally opposed engine is very good, they have decisively given up the research and development of this engine structure, and continue to dig deeper into the traditional engine with a wider application and lower cost!

At present, only Porsche and Subaru have been stumbling on the research and development of horizontally opposed engines, which is one of the main reasons why these two major car brands have not been able to be popularized before, the cost of the engine is higher than that of other manufacturers, until the technology has broken through in recent years, and low-cost models have appeared!

Wang Jun has noticed since the moment he came into contact with the alien engine that the alien engine is a structure with the piston and the cylinder block horizontally opposed!

The Correns Empire, which has entered the interstellar age, has obviously developed to the limit in terms of internal combustion engines, but they have not completely discarded the internal combustion engines, and are still constantly upgrading, and the engine of the TW02 model is only the lowest level!

But even the lowest-level, this TW02 model of the alien engine also perfectly solves some of the drawbacks of the horizontally opposed engine, and further improves the energy conversion efficiency, that is, improves the combustion efficiency and improves the power output!

But!

Wang Jun can't completely copy the engine of the TW02 model!

Because, the fuel on the earth is not the same, the materials are not the same, at least the volume of the cylinder block cannot be the same!

This is an extreme test of Wang Jun's wisdom!

"Brother Jun, do you need me to stay and help?"

Hu Fei looked at Wang Jun standing there in a daze, and couldn't help asking.

Wang Jun came back to his senses, many mechanical structures in his mind were still flickering, and he shook his head at Hu Fei and said, "No need, Brother Fei, you go to the club to get busy, prepare for the Dubai game next month, and tell Yang Zi to train them and step up training!"

Hu Fei smiled: "I know, then I'll go first, if you need anything, call me at any time, or find Professor Liu Xin!"

"Done!"

Wang Jun agreed casually.

Seeing Hu Fei leave, Richard looked at Wang Jun expectantly and asked in a low voice, "Sir, what are we going to do?"

Wang Jun looked around and said, "Cover the cameras first!"

Richard was already looking forward to the start of the experiment, and he was stunned when he heard this, but he immediately understood that the engine technology was absolutely secret and could not be filmed, so he immediately covered several cameras on the bench!

Wang Jun's expression gradually became serious, and he immediately started to make it with the materials in the laboratory, and Richard was listening to his command to help make some parts!

In the monitoring room, Professor Wu, Xu Gong and others saw the picture of the laboratory disappear, and they could only see a pitch black, all with a helpless and bitter look!

"This little brother seems to be very defensive!"

Professor Wu said helplessly.

Xu Gong said solemnly: "I don't know where he is from, his understanding of machinery is simply one level higher than ours, I want to communicate more with him in the future!"

"I don't know where he came from, he doesn't pay any attention to us. Yesterday I heard Lao Yang say that he met a young man who solved a world's mechanical problem, and I didn't believe it at the time. Now I believe that there are indeed some young people who are very powerful, maybe that one will have a fight with this little brother we meet now! It seems that our Chang'an is Crouching Tiger, Hidden Dragon!"

Professor Wu said with emotion: "Let's go back and take a rest, just relax recently, go to school, participate in the research of new achievements with Lao Yang, and continue to research in the future, I also have some ideas after reading the results of my little brother!"

"I'll go too!"

Xu Gong hurriedly said: "Take a break and think about it, and then continue!"

Several other experts have also said that they will participate in the research of Chang'an Jiaotong University, which is a major event in the history of domestic machinery development, and they must all want to participate.

The group left!

And Wang Jun is very busy at the moment!

The structure of an engine is very complex, and there are many parts involved!

Among them, most of the parts have to be remade by Wang Jun, because these are all redesigned by himself, and they are different from all the engines on the earth now.

Fortunately, Richard is a real expert, otherwise he might not be able to make high-precision parts!

was busy until the evening, during which Wang Jun and Richard never went out except for lunch, and they didn't eat dinner, and they insisted on it until they assembled a brand new engine!

If someone else, absolutely not believing in such a thing, can build a completely new engine in a day?

Fantastical things!

In fact, Wang Jun really did it, because he had already thought about it in his heart, so he was actually not completely on his own, with alien engine and mechanical knowledge as a reference!

Or rather, this is not an experiment, but a straightforward process!

Dingdingding......

Squeak squeak......

The engine is finally assembled!

Wang Jun looked at the boxer engine designed and manufactured by himself in the middle, and his heart was full of a sense of achievement!

Although he hadn't ignited the test yet, he already had some rough parameters in mind!

Richard screwed the last screw, and stood there in a daze with a wrench, looking at this engine full of mechanical beauty, and his heart was extremely satisfied.

He kept saying in his heart - this is his own doing!

Of course, Richard also clearly knows that he is just the executor, everything is made according to Wang Jun's design, and he will do whatever Wang Jun asks him to do!

Finally, the engine was assembled!

"Sir, you really are the greatest mechanic in the world, there is no one!"

Richard looked at Wang Jun's incomparably young face, and praised from the bottom of his heart, for the first time that he was able to become Wang Jun's apprentice, he was full of a sense of superiority, and he felt that it was a gift from God to be able to learn from Wang Jun!

Wang Jun looked at this engine, his expression was calm, and he was a little excited in his heart.

However, he suddenly received a system prompt: "Congratulations to the master for designing and producing an internal combustion engine completely by himself, and reward the design institute with the opportunity to use it once, and the design institute will automatically help the master improve the detailed design of this engine according to the master's design ideas!"

Wang Jun's eyes lit up, and he didn't answer when he heard Richard's words, but quickly entered the design institute of the system, and the design institute had already given a design plan!

A similar, but more precise and perfect engine design scheme appeared in Wang Jun's mind, improving the deficiencies of many details!

"Cool!"

Wang Jun said excitedly in his heart that he liked to deal with the design institute the most.

Because the design institute will give him a new and complete knowledge of aliens.

This time, too, the design institute told all the details of its design and the detailed knowledge points involved, and all of them were entered into Wang Jun's memory, which contained a large number of knowledge points about alien civilizations.

In this way, Wang Jun can quickly understand, almost as simple and fast as fusing memory!

"Sir?"

Richard saw that Wang Jun had been in a daze and didn't speak, and shouted worriedly.

Wang Jun immediately sobered up, and said with an excited expression: "I'm fine, I just thought of some better designs, and we can still improve this engine......"

As he spoke, he immediately modified some of the design drawings in front of him, and then said to Richard: "Richard, you help me disassemble these parts, and then make a few parts according to my drawings!"

Richard hurriedly agreed, "Yes sir, I'll start right away!"

The two of them immediately began to work again!
