Chapter 263 The Function of Air Cooled Engine
Mizuki University, Department of Automobile, Department of Automobile Body.

"Have you gone to see that Porsche?" Holding a teacup, Gu Pan looked at Liu Qingsheng, who was immersed in drawing, while still reminiscing about the yellow car that he had just inspected carefully.

"I haven't got my turn yet, have you gone?" Liu Qingsheng knew that this man must be here to show off. After seeing the car, he must have something to say, so let him talk about it, so that next time he looks at it by himself There is also a reference.

"Well, I went, I just went in the afternoon, two hours is a bit short, the boss is really careful, you have to wear a white coat and white gloves when you go in and visit.

It is not allowed to touch it directly with hands, for fear of being scratched.

Don't tell me, I tried it, and there is no oil stain on the engine. The German processing quality is really good. "

"It's not just that the Germans are good, but the little days, the old and the ugly, which one is worse, but we don't have samples here. You watched it for two hours, what do you think?"

"The gap is big, it's really big, I have practiced in FAW, and I have seen the newly imported Audi. Compared with this, it is really far behind.

But even the Audi 100 we assembled is a bit worse than the original one, and it still uses imported engines.

This engine is really small, with a displacement of more than 3 liters, and it is still air-cooled. It is so small that it is so compact that it makes the scalp tingle.

You didn't look at his aluminum alloy cylinder body, the pure cast cooling fins are so neat as if they have been machined.

Aren't you an engine engineer? I strongly suggest you go back and take a good look. I don't know if the department head can allow it to be dismantled and studied. " Gu Pan smacked his lips, feeling a little unfinished. In fact, two hours is not enough to take a closer look at a car.

Several young teachers were talking, and more were waiting. Wang Xu's actions this time brought him good popularity. No, when Wang Xu appeared in the teaching and research room of the car body on a motorcycle, the teachers and students who were visiting They all stopped and greeted him warmly.

Wang Xu waved his hand and let them do whatever they wanted. He just came to take a look. Since the car was delivered, he didn't come to take a look at it. After all, it was his own, just to see the living environment of the car.

The garage is provided by the body teaching and research department. There used to be a pile of scrapped trucks here, but now they have been removed.

The garage has been thoroughly cleaned, the concrete floor inside and out is polished, there is a ditch in the garage, and the car is parked on the ditch. watch.

Therefore, it is completely possible to observe the chassis structure of this car carefully from the ground, which makes these purely theoretical players who have never seen this kind of suspension quite excited.

After all, they are all professionals and know what to look at, so they look very careful. They are really observing and measuring from the inside to the outside, from top to bottom, very carefully.

This time, the Department of Automobiles gives priority to young teachers and doctoral students to visit and study. When the car comes, it is natural to make full use of it. In the future, such resources can be satisfied by any 4S shop, and there are many craftsmen who can repair such cars.

But in this day and age, that's really a rare item.

In Wang Xu's previous life, the first sports car would not arrive in the imperial capital until the end of next year. It was also the first imported sports car in China, a Ferrari 348. The owner was Li Xiaohua who made his fortune selling tonic water in his childhood.

That car had the autograph of the chairman of Ferrari on it. Later, many foreign leaders would sign on that car when they came.As a result, the car has basically never been driven since the date of purchase, and it has not even been washed, and it has become a complete exhibit.

Wang Xu didn't think it was very interesting. An industrial product was made so grand, and it really gave him face.If it wasn't for Wang Fei's birthday gift after all, it was a bit commemorative, and he planned to drive it from time to time. He would have let the teachers of the automobile department take it apart for fun.

The engine of this car is actually quite good. With a displacement of more than 3 liters, it has more than 300 horsepower since it is aspirated, and it can burst out a strong power of nearly 400 horsepower after adding a twin-turbocharger. If it is not because it is pure It was cold, and Wang Xu was planning to copy it.

However, Wang Xu doesn't have all the technology for this thing, and it's quite troublesome to make it out. It's just a matter of taking time to draw the general assembly drawing. The imitation of specific materials and the like has to be made by the automobile department itself.

The key is that it is really not cost-effective to get an air-cooled engine now. In the future, cars will be water-cooled, and air-cooled engines rarely appear.After all, air-cooled heat dissipation requires sufficient air flow, and it is easy to overheat in traffic jams, which is especially annoying.

However, due to the simple structure, easy processing and low cost of the air-cooled engine, it is very useful to make something special.

For example, the three jumpers in the air, that thing uses an air-cooled piston engine.This thing is really not that complicated, except for the rotor above, there is no technical content, and Wang Xu has already worked on the material of the rotor in a big project.

Isn't it just carbon fiber? In the entertainment system, it is a speaker case, which is purely for decoration.

Although Wang Xu couldn't figure out how to use such a good carbon fiber to make a shell, besides showing some patterns, there is no use.But thinking about the fact that there are still idlers using that thing as a mobile phone case in YouTube, he is relieved.

It can fly with No. 95 gasoline and has a 20-meter runway. For the current army, it should be a pretty good air supplementary force. It is also pretty good to send supplies to some remote areas.

But it's a pity that Mizuki's aircraft major was later given to the Imperial Aviation Academy, and they might have to join forces with them to get that thing, but it doesn't matter, anyway, the Iron and Steel Academy was dragged down by the Materials Department.

It is not impossible for the automobile department to drag the Academy of Aviation into the water, right?

The only problem is that the Porsche engine seems to be a bit too powerful. Its power is a bit too big, and it may not be able to pull a ton of cargo when it is made into a rotorcraft.

Let’s discuss it with the teachers of the automobile department later on. An air-cooled piston engine is better than a light aircraft than a car.

In fact, there is a very good air-cooled piston sitting under Wang Xu's butt, and Harley's motorcycle engine has more than 100 horsepower.It's a pity that Wang Xu doesn't have a blueprint for this engine, so it's not so easy to imitate it.

But if it is really needed, it is not a big problem. This kind of engine can be imported directly from Ugly Country, or simply remove the two cylinders from the Porsche model, and it will take some time to get it out. Some can't control it anymore, and I don't know where to get some funds.

Didn't you see that China is really engaged in engine research?

To be honest, there are too many things being thrown out now, and even top universities like Mizuki are a little bit unable to hold on.

Therefore, this year, Wang Xu does not intend to toss about new things.He can also save emotion points, which can be used to exchange technology for something with higher technological content, such as a digital camera. The main reason why Wang Xu has been unable to exchange it is that it is expensive.

Whether it is a digital camera, a digital video camera, or an image processing workstation, these things involve complex semiconductor chips, and the prices offered by the system are quite high. Wang Xu estimates that he will have to save at least a year and a half to have a chance In exchange.

This year, if there is no money, then just modify the corners and corners of the existing things. It is not good to make them too big. Well, even thinking about it this way, Wang Xu feels a little guilty.
