Automotive Black Technology Chapter 83: ：K2 Racing Team

Watching the three academic masters discussing the structure and theory of go-karts, Li Fanyu was also interested. Unconsciously, the conversation lasted until midnight, and he simply fell asleep on the sofa.

Go-karts are something that can be highly DIYed, with simple technology and high error tolerance, and the accessories are very cheap. Many enthusiasts and civilians are willing to do it themselves to assemble a unique car.

Because there was a sponsor to pay, the three top students chose the same city regardless of the price, and frantically chose next-day delivery for large items... As a result, a lot of parts were delivered early in the morning.

The top three students directly ignored the structural issues of the car. In fact, there is nothing to study about the structure... The steering system of the go-kart has a steering column that drives the pull rod. When you turn the steering wheel, the wheels move with it. The steering ratio is 1:1. , it can be said that there is no technical content.

So they focused their main research direction on engines and gearboxes.

Two-stroke engines are also very simple; what is a two-stroke? A two-stroke cycle is completed in two strokes. Just like the piston movement between men and women, insertion is one stroke, pumping is one stroke, and one action is a standard two-stroke...

This is not dirty, the black humor and joy of hardship of industrial people are everywhere. Take bolts as an example; when the lathe processes threads, the threads processed on the inner wall are called female buttons, and the threads processed on the outer wall are called male buttons. After the two threads are screwed together, the deep female buttons tightly cover the long male buttons. .

There are also the most common screws, why are the matching ones called nuts? Get a set and experience it yourself.

The simple working principle of the two-stroke also means that it has good reliability. Although the fuel consumption is relatively high, the power is higher than that of a multi-stroke engine, and the service life is long and daily maintenance is simple.

So, after the three top students received the package, the poor Suzuki GN250 single-cylinder engine was immediately dismembered...

After seeing the thick cylinder and small piston, the three top students immediately expressed their disdain for the manufacturer - the performance can definitely be improved.

So, the three people immediately decided to go to Zhengxin Company to conduct research modifications on the engine and gearbox.

Li Fanyu covered his face, damn, you are relying on me. However, with the expectant eyes of the three top students looking like dogs, Li Fanyu still called Pan Qiang. After a while, Zhu Zhu drove a pickup truck over and took the people and parts to the company.

Although many types of cars have been modified, they are all done automatically by the X modification workshop. Li Fanyu was still very interested in the manual modification of the three people.

Four people worked in an idle workshop for a whole day, and finally modified the engine in the afternoon. Even though I had all the tools I needed, I still wasted a lot of effort.

When the four of them worked together to assemble the kart, they felt a huge sense of accomplishment.

Add oil to the car and open the starting valve. The car shook violently and made a screeching sound.

Li Fanyu bared his teeth, his voice was a bit low...

However, the four people were very happy that the engine could work normally, and immediately urged anyone to go up and give it a try. Li Fanyu stepped up with one kick. I spent the money on his cat, so I have to do the first shot!

Because it is a continuously variable transmission car and there are no gears, you basically just step on the accelerator to go and step on the brake to stop. However, due to the modification of the engine, with the enlarged cylinder block and increased displacement, the power also increased. When you step on the accelerator, the car feels like it's moving forward.

The chassis of the kart is extremely low, only 4 centimeters above the ground, so the relative speed felt by the driver will be two to three times faster than the actual speed.

The practical application of this feeling is that Li Fanyu, who was sitting in the car, bared his teeth and cracked his mouth, yelling, "It's so fast to hold the grass! It's so awesome to hold the grass!"

Then the three academic masters on the side looked indifferent: "It shouldn't be, the cylinder has been enlarged by 30%, and the displacement has been increased by 150ml. How can it achieve this speed? Why is that idiot so excited?"

The company's parking lot is not flat, and the speed of the car at this time is only about 50-60 miles, but to Li Fanyu, it feels like 1,518...

However, the three top students don’t know that even at this speed, Li Fanyu’s Xapp still has a driving speed BUFF...

Li Fanyu drove around twice before being stopped by the impatient Liu Qing.

Looking at Liu Qing who was shouting in the car, and the speed of the car which was not much faster than the electric car, it was Li Fanyu's turn to look contemptuous: "Evil! Why are you so excited when you drive so slowly!"

……

Liu Qing got out of the car, quickly picked up her hand and took a few photos, and sent them to her circle of friends to show off. Less than two minutes after sending the message, Cheng Ke called.

Go-karting is such a fun thing, why is there so little about Keke! So the four old men watched with pained faces as Cheng Ke drove his cute go-kart slowly and yelled in the empty parking lot.

When she had enough fun, she jumped over. Before the four of them could say anything, she excitedly suggested: "Let's go to a go-kart race! There is a go-kart track east of the city park. Every week There will be go-kart races.”

The eyes of the three top students immediately flashed, and they used their completed cars to compete in the competition? Well, this is a very fulfilling thing. Didn’t Sister Ning say that karting can also be considered a formula?

After receiving the support of three people and Li Fanyu's abstention, Cheng Ke ignored the objections, raised his arms and suggested: "Why don't we form a team! I will be your team manager!"

The eyes of the three top students are shining brightly; the Formula Team, it feels so awesome! They automatically ignored the word "elementary" mentioned by An Ning.

Li Fanyu covered his face and complained in his heart: "Do you really think you are just playing go-kart racing?"

When Cheng Ke met something he was interested in, his mobility was at its maximum. He took Li Fanyu and the three top students to the go-kart track office and spent 1,500 yuan to register a club.

After seeing a bunch of extremely low names on the club list, Ke Ke had a deep shiver.

"Niuniu Hot Dry Noodles Team", "Anjia Squid Team", "Yaya Refrigeration Team", "Good Vision Glasses Team", "Er Gouzi Chao Clan Dog Meat Restaurant Team", "Let You Enjoy Spicy Hot Pot Team", "Royal & Peak Team" "......

Li Fanyu crossed his arms, soothed the goosebumps on his body, and asked weakly: "What name should we register..."

Liu Qing: "Why don't we call them the five-person group from the University of Technology!"

Xu Fufang: "Why not call it XLWCL!"

Wang Yu: "Is it the initials of your name? Why do you put you first?"

Li Fanyu "..."

In the end, it was Cheng Ke who made the decision with a serious face: "Let's call it K2!"

According to her explanation; K comes from the Semitic letter Kap, which means an open hand. The open hand has five fingers, which represents the group of five. In addition, K is also used in physics to represent the torsion coefficient of vibration, and in numbers, 2 is a barrier between odd and negative numbers, representing the best choice in nature...

Seeing the top three students touching their chins and nodding frequently, indicating that the name of the team was very impressive, Li Fanyu sighed deeply.

Classmate Cheng Ke, you are really too scheming. Is it really okay to tease three top students like this?

And the world of academic masters is really difficult to understand! K=Ke, K2 doesn’t mean Ke Ke, you three are stupid!
