"No, it's not nothing!" One of them, a fat, blond middle-aged man who looked very young, said.

This person is Gordon Guevara. This 49-year-old designer officially served as the global design director of Mercedes-Benz in 2008. The new generation of Mercedes-Benz R-Class, E-Class and CLS are all produced by him, and the engine is even more important.

Authoritative experts.

"Take a good look at these places!" Guevara pointed to the star pattern around the engine casing.

"These are not decorative patterns at all, but the positions of the screws, right?" Guevara looked at Chu Feng without blinking and said. Although it was a question, anyone could hear the affirmative tone in it.

Everyone looked at the place where Guevara's finger was pointing, and some even touched it gently with their fingers, but they didn't feel any protrusion or incongruity.

"Not bad!" Chu Feng nodded, confirming Guevara's statement. Those are indeed screw positions, but unlike the screws that usually protrude a large area, the fixing screws of the S9 engine cannot be seen protruding at all.

, is directly integrated into the engine components.

And because the precision is too high, coupled with the Van der Waals effect between the metal parts, the two parts are almost combined into a whole, and the gap cannot be seen from the outside, so everyone mistakenly thinks that there is no screw connection.

This result made everyone dumbfounded. They originally thought it had some special structure, but now it seems that it is very simple, it is a problem with the manufacturing process!

However, in comparison, they prefer a special structure rather than a manufacturing process problem, because in this case, they have no way to perfectly copy this V8 engine!

Guevara sighed and lost interest in this V8 engine. If they were asked to specially make this engine, they could barely make it, but it was still impossible to make it in large quantities!

With this precision alone, making screws is exhausting, not to mention that a car doesn’t only have these few screws!

When Chris saw Guevara's expression, he knew that things were not simple.

"Guevara, how about it?" Chris still didn't give up. He really didn't believe that with his own technology and ability, he couldn't make a car engine?

"Mr. Chris, to be honest, this kind of engine requires dozens of highly skilled professional craftsmen to hand polish...the parts to manufacture!"

Guevara said with some reluctance that the so-called skilled workers mentioned here are different from those in China.

In China, when talking about skilled workers, many people will have some simple images in their minds, covered in oil and dirt, or doing boring car and truck work for many years, but you will never associate them with luxury cars and villas.

But in Germany, the status of skilled workers is very high!

Unlike the teachers, civil servants, and doctors respected in China, in Germany, where the manufacturing industry is developed, skilled workers are a career that many young people dream of, and technical colleges are the schools that German parents expect their children to apply for!

The reason is also very practical, that is, in Germany, the wages of these technicians are even higher than the national average wage in Germany!

The wages of graduates from these technical schools are generally higher than those of university graduates. The average annual salary of white-collar university graduates is about 30,000 euros, while the average annual salary of technicians is about 35,000 euros. Therefore, the wages of technicians in many industries are much higher than those of ordinary civil servants.

, even higher than university professors.

What Guevara meant by saying this was to tell Chris that if you want to make one for fun, you can do it, but don’t think too much about mass production!

If Chu Feng next to him didn't expose Guevara, if he took this engine apart and took a look, he would know that the piston and cylinder liners inside could not be polished by hand!

Because the grinding material limits such accuracy, for example, the most common grinding tool required for grinding is sandpaper. Sandpaper has coarse and fine meshes. When grinding, you should grind from coarse to fine, and try not to skip the mesh. For example

For example, if you use 120 grit to polish an object, then you should use 180 grit, and then use 220 grit to slowly increase until the roughness meets your requirements.

But the accuracy of the S9's engine is between 1 and 2 nanometers. Is there any abrasive that can be finer than 1 nanometer? Use electronic polishing?

Therefore, if you don’t have such sophisticated equipment, don’t even think about making such sophisticated equipment!

Once the deviation occurs, it means the occurrence of wear. Once the wear occurs, the life of the equipment will also decrease.

"Mr. Chu, the material of this engine is not aluminum alloy, right?" He tapped the smooth engine casing lightly, and the sound that came from it was different from the echoes of other engines, which made Guevara feel confused.

"Yes, this is our latest titanium alloy material, which is different from ordinary engines." As soon as these words came out, the engineers around him looked at Chu Feng with strange eyes.

This guy is such a spendthrift. He is not making car engines, but aviation aircraft? This technology is more than enough for aerospace aircraft!

Chris's heart moved, he stepped back slightly and came to Chu Feng and asked doubtfully: "Can this kind of engine be mass-produced now?"

"Of course not." Chu Feng replied matter-of-factly, which made Chris feel a little more comfortable. It turns out that Origin is not capable of production.

"The production line hasn't come out yet. At least we can't mass-produce it until the production line comes out!" Chu Feng made a sharp turn and almost missed everyone's waist. What did he mean by gasping for breath?

Chris was so choked that he couldn't say a word, but thinking about it, what Chu Feng said was not unreasonable, but it seemed that he knew something extraordinary.

"You mean that Origin can mass-produce titanium alloys? And it has the ability to mass-produce titanium alloys?"

Chris regretted a little after asking. With so many people around, it was a bit too abrupt for him to ask such a question.

"The mass production of titanium alloys has been solved by Origin. This is not a problem at all!" Chu Feng shrugged, not intending to be secretive. Now that Origin has the ability to protect the technology, Origin is no longer the same Origin as before.

"Mr. Chu Feng, can I visit the production line after it is completed?"

Guevara asked with some anxiety. He was really curious about what kind of production line could achieve such amazing precision requirements. This was like rubbing the precision they were proud of on the ground!

“You’re always welcome.”

Chu Feng smiled and nodded, agreeing with the other party's opinion. Some things cannot be learned by just watching.

Just like F22 and F35, it’s hard to find a lot of videos and even high-definition photos of them. Tourists are even allowed to take close-up shots, but how many other national construction companies can do this?
