The engine is the embodiment of the industrial base, and without a modern industrial base, there will be no advanced engine. It also involves all aspects of materials, processing, and so on.

Throughout the world, MTU companies are at the first-class level in the manufacture of engines, not only tank engines, car engines, warship engines, etc., are star products.

The next day's visit, it was the MTU company, when the group walked into this famous international company, they saw a cleaner and tidier scene than the production workshop of the Leopard 2 tank, not to mention the oil on the ground, not even dust.

"In order to make the assembly of the engine more clean and tidy, we use a dust-free workshop during the final assembly."

Even if it is a grain of sand, falling into the engine, will accelerate the wear and tear of the engine, so the MTU company, which strives for excellence, adopts a dust-free workshop.

Of course, you don't have to reach the level of the electronics factory, but the shoe covers, dust caps and other equipment are still necessary, everyone has seen such excellence for the first time, and they all have feelings from the heart, no wonder people's engines can be the first in the world, an assembly link, are so high standards.

Eric, the head of the company, personally received and introduced to everyone.

"We here, civilian diesel engines and military diesel engines, are produced on the same line, and the current batch is our 331 engine. Its military version was used in the Leopard-2 tank. "Compared to the military model, this engine has reduced the speed to 2,400 rpm for stability and durability, and the power has been further reduced. ”

At this time, the beginning of the production line started from the assembly of the cylinder block, looking at those bright cylinders, everyone's eyes widened, and Zhang Baolin came to the front and observed carefully.

"No, this cylinder is 8-cylinder, right?" He couldn't help but ask.

The Leopard 2 tank used a 12-cylinder engine, and now, he sees an 8-cylinder engine, what is going on?

"This civilian engine of ours is a series." Seeing that Zhang Baolin was interested in this cylinder block, Eric knew what he was thinking and continued to introduce: "Our 331 series engine has 6, 8, 12-cylinder turbocharged and turbocharged intercooled models, so that different power outputs can be achieved, and at the same time, the single-cylinder displacement is exactly the same, and the basic structure and general arrangement type are almost the same. This can significantly reduce production costs. ”

A series of engines!

Tank engine, can be said to be the most difficult, the need for power is the largest, after changing to civilian, may not need such a large power, at this time, they have to reduce the power, reducing the number of cylinders is the most convenient, the overall structure is the same, many parts are common, the cost is greatly reduced.

Zhang Baolin's eyes lit up, he can still do this, this is a good plan, and he can do it in the future!

The production line has passed, and when it comes out, there are several workshops next to each other.

"Everyone, please come here. Let's visit the foundry of the cylinder block. Eric was about to leave with everyone, and at this moment, Qin Zhenhua seemed to have discovered something, and couldn't help shouting: "Next to this, it's the turbocharger processing workshop, right?" Can we go in and have a look? ”

Opposite a workshop, you can see the logo there, it is the shape of a small fan, so, Qin Zhenhua guessed it, nine times out of ten, it is the turbocharger production workshop, which is too attractive to him.

If you want to make the technical progress of the engine, you have to increase the power of the single cylinder, turbocharging is the only means, and the processing of this blade is also the top priority after Qin Zhenhua's plan to go back.

Since I've come here this time and seen it, of course I'm going to go in and have a look.

Hearing Qin Zhenhua say this, Commander Huang also became interested: "Can we go in here and have a look?" ”

Qin Zhenhua is a small entourage, very young, his words, the other party can not listen, but Commander Huang's words are different, and as Commander Huang finished speaking, Minister Zhu also showed interest, so Eric could only disrupt the original plan.

Just look, what can a group of people from backward countries understand?

Take them, go in and go around, and then come out, it won't take too long, after all, this workshop is not big, and the area is less than one-twentieth of the assembly workshop.

"Here, the turbochargers for our engines are produced." Eric said, leading the group inside.

Just now, Qin Zhenhua walked here, and then proposed to go in to visit, so when he opened the door, he was at the door, and a new world was displayed in front of his eyes.

He swept to the CNC machine tool at work at a glance, the whole machine tool is spotless, the paint of the shell is brand new and shiny, in the center of the lathe, inside the cover of plexiglass, there is a workpiece being processed, this kind of workpiece is completely sealed and processed, which can ensure the safety of the operator, and can also ensure that there will be no additional interference in the processing, which is a common way of CNC machine tools.

And, what did you see?

Now the workpiece is rotating around a certain axis! It's definitely not a three-axis CNC machine, it's a five-axis one!

So, the young Qin Zhenhua had forgotten everything, he was so excited, and he recalled in his mind countless times that it would be much more convenient if there was a five-axis machine tool to process the impeller, and now, I finally saw it, so I didn't hide my excitement anymore, and ran there.

Five-axis linkage CNC machine tool, five-axis linkage CNC machine! This is the first time I have seen a self-made CNC machine tool that has to write code manually, several generations ahead!

Qin Zhenhua thought like this, his eyes finally turned from the bed of the machine tool, and looked to the side, the machine tool itself has a display screen, there are various operation buttons, and at the same time, on the side of the machine tool, there is a computer desk next to it, and there is a personal computer on the computer table?

The beige shell, the TV-like protruding display, the keyboard and body underneath are put together, and the whole computer looks like a delicate household appliance!

It should be Apple II, right? Apple's latest computer? Don't look at the volume is less than one-tenth of your DJS-130, but the performance is many times more than that!

At this time, in front of the computer, there was a female technician with a slightly frowning brow, she was very unhappy when she saw someone she didn't know running in, and she recognized it.

"Why are you again, what are you doing here?" As soon as the girl's voice came out, Qin Zhenhua was also stunned, at this time, he had already run to the CNC machine tool, panting a little, pointing to the machine tool, and said, "Visit, come and visit." ”

She stood up, clasped her hands in front of her chest, a sneer appeared at the corner of her mouth, and said, "Are you interested in CNC machine tools?" ”

The tone is exactly the same, and the words are all in English, just like asking Qin Zhenhua yesterday, are you interested in heavy trucks.
