Chapter 303 The Art of Repaying Gratitude

Chapter 303 The Art of Repaying Gratitude
In the previous life, when mentioning the rotary engine, the first thought that popped up in people's mind was to link it with the Mazda Motor Company of the island country, as if the rotary engine was Mazda's patent.

But this is not the case. It can be said that the rotary engine is a business card of Mazda, but if the rotary engine is Mazda's patent, it is a bit suspicious.

In fact, the rotary engine was not invented by Mazda, but was invented and patented by a German engineer Figas Wankel. Mazda just bought the right to use this patent with huge sums of money, and It is also the only car manufacturer that has mass-produced rotary engines and successfully loaded them into vehicles.

In order to achieve the goal of mass production and loading, Mazda has paid a huge price. It can be considered that it is Mazda that makes the rotary engine known to more people. It is Mazda that promotes the rotary engine. , so when it comes to rotary engines, the first thing people think of is this company.

The reason why the rotary engine is so special lies in its working principle, which is very different from the reciprocating engine we are familiar with.

In addition to the rotary engine, the automobile engines used at this stage are basically four-stroke reciprocating engines. When the engine is working, the piston makes a reciprocating linear motion in the cylinder. In order to convert the reciprocating linear motion of the piston into a rotary motion, the A slider-crank mechanism is required.

The linear motion is converted into rotary motion, which inevitably produces energy loss, and the output torque of the engine is thus greatly limited, while the rotary engine changes the reciprocating motion to a large extent. This defect of the type engine.

Compared with the reciprocating engine, the rotary engine cancels the unnecessary linear motion, and the expansion force generated by the combustion acts on the side of the rotor, thereby pushing one of the three faces of the triangular rotor to the center of the eccentric shaft, thereby generating rotational motion, which will The energy generated by combustion becomes output torque, which is sent to the car's powertrain.

Because of such motion characteristics, the rotary engine with the same power not only has smaller volume and lighter weight, but also has very little vibration and noise during operation, which has irreplaceable advantages.

Mazda's classic RX7 series sports cars are loaded with their own optimized rotary engines.

Of course, the rotary engine has many advantages, but the disadvantages are also obvious, such as high fuel consumption, heavy pollution, and short life. The engine is definitely a dazzling pearl in the history of engine development. In other words, commercial value is no longer enough to measure the historical significance of this engine.

The rotary engine was initially noticed by the world because it won the championship in the Le Mans 24 Hours Endurance Race, but the turning point occurred in 1992. The FIA ​​explicitly prohibited cars equipped with a rotary engine from participating in any international car races, coupled with environmental protection regulations Getting stricter, there aren't actually many applications for rotary engines.

Coupled with the fact that the reciprocating piston engine has greatly improved in terms of power, quality, and emissions, the rotary engine did not show obvious advantages. Therefore, in the previous life, except for Mazda, no other car manufacturers were interested in it. This engine shows too much enthusiasm.

However, from the perspective of engine development history, as long as the shortcomings of rotary engines can be overcome, in the future, rotary engines may not be able to replace reciprocating piston engines and become the mainstream of automotive engines.

If Mueller really wanted such an invention, Zhou Fei would not mind giving him the rotary engine as a big gift to repay him for his help to Feichi during this period.

After making up his mind, Zhou Fei first went to the system to study the working principle and specific structure of this engine in detail. After exiting the system, he found that it was getting late. Considering that there were still a series of activities to participate in tomorrow, Zhou Fei Fei decided to suspend the design of the rotary engine for now, and wait until tomorrow's work is over before doing it.

At 500:[-] a.m. the next day, Jiang Yang, as an alumnus of the Technical University of Munich, donated a total of [-] million US dollars of scientific research funds to Muller's laboratory to support the scientific research of his alma mater.

Considering the confidentiality of this itinerary, Zhou Fei did not attend the donation ceremony that day, but in the afternoon, Zhou Fei, Mu Le and Jiang Yang went to the industrial park to inspect the land conditions. The specific location of the production base has been determined.

Next, as long as Muller comes forward to buy the land, and then find the corresponding construction team to start construction.

After finishing this inspection, Zhou Fei and Jiang Yang returned to the hotel. The relevant precautions have been emphasized to Muller. Zhou Fei has to stay in Munich for a while before Muller completes these things. .

"Brother Fei, if there is nothing else to do, then I will return to the United States tomorrow, and the matter over there is not over yet." After returning to the hotel, Jiang Yang said to Zhou Fei.

The Audi A3 has not yet officially accepted reservations. At present, only Zhang Xiang is busy in Europe and America. Jiang Yang wants to go back early to help.

Zhou Fei smiled, "Wait for another two days, when the time comes, you and I will send a big gift to Professor Muller. I have already greeted Brother Xiang."

"What kind of gift?" Jiang Yang became interested all of a sudden, "Let me tell you first, if it's linked to money, then I advise you to stop working, the teacher won't accept it."

"Don't worry, this time it must be what he likes, and he will be very happy to accept it." Zhou Fei smiled mysteriously, but did not elaborate.

The more Zhou Fei was like this, the more curious Jiang Yang was, what kind of gift could make Zhou Fei so confident that Muller would accept it?
After Jiang Yang left, Zhou Fei washed up first, then turned on the computer and began to design the relevant structure of the rotary engine. The computer was borrowed from Muller, and all the design software was complete.

However, Zhou Fei is not going to design all the rotary engine structures this time. If so, then it is just a free patent to Muller. With Muller's personality, he will definitely not accept it.

The best way is to have an idea first, sort out the general technical plan, make a semi-finished product or something, and then bring it to Muller, hoping that Muller can participate in the project and let him be in charge of the project For the development work, Zhou Fei will randomly dial again when the time comes, and everything will be done!
Muller gained a sense of accomplishment and realized his long-cherished wish, while Zhou Fei repaid his favor and developed a rotary engine for Feichi at the same time.

Thinking of this, Zhou Fei couldn't help but smile, and then he started to do it seriously.
