Start with a blacksmith shop

The three of us visited the auto show for two days and three days in a row. Except for the first day, we were really looking at the cars.

In the remaining two days, Li Zhenhua also joined the queue to see the car.

And they took a lot of photos and put them together,

We were discussing whether the car lights are round, whether the butt of the car is sexy, whether the exhaust pipe has serious carbon deposits, whether the oil nozzle is smooth...

A few people stayed until the end of the auto show. Of course, there was no gain in the process.

For example, Li Zhenhua got all the engines he wanted at the auto show, and he also collected many advanced models.

Of course, this was his harvest on the first day. As for the harvest on the second day, I won’t go into the specific details. Anyway, the three people watching the auto show did not return to Guo Shugui’s villa that day, and even Li Zhenhua slept in the hotel.

When I got up the next day, my waist was very sore anyway, and of course I had lost some weight on my wallet.

On the third day after the auto show, the three of them drove Guo Shugui's pants towards the small county town.

Why is it the third day? Because their schedule these days was too busy, they took a day off.

On the way back, Liu Xiaodong, who used to be very brave, now had a sad face.

With a wry smile, he said to Li Zhenhua: "Brother Hua, please do me a favor. If Wang Mei asks about me, please help me!"

"Damn! Did he find out about my brother and sister? What a woman's damn sixth sense!"

Guo Shugui, who was driving at the moment, was looking back from the rearview mirror with a look of gloating on his misfortune.

"Oh, I don't know what happened to Wang Mei, but I feel like she discovered something!"

Li Zhenhua looked at Liu Xiaodong with a wry smile and felt that this matter was really tricky.

"Okay, I'll cover you when the time comes. He didn't catch you anyway.

Otherwise, just wait until we get home and you can just pay Wang Mei a visit.

I feel pity for you when I think about it. Alas, I have a moment of silence for your poor waist! "

The car drove quickly towards the small county town, and of the three people in the car, two were in a good mood, and the remaining one was in a somewhat responsible mood.

The car drove all the way back to the county town and placed Li Zhenhua in the blacksmith shop. The two left without staying here longer.

Liu Xiaodong left the blacksmith shop, told his family, got in the car and went to Wang Mei's graduate school.

Anyway, Liu Xiaodong seemed almost tired that night, and there were no other serious consequences.

Guo Shugui returned to the company he had not managed for a long time. This time he went back and talked a lot with his old man.

He also knew that he could not continue to play like this, and he had to stand up for some things.

Li Zhenhua stood at the door of Lao Li's blacksmith shop again, looked up at his home, opened the door, and returned to the home he had been away from for nearly a week.

After simply cleaning up the lower floor and opening the rolling shutter door, the blacksmith shop resumed business.

A long time passed without realizing it, and a week had passed since I came back from Peking.

Just yesterday, Li Zhenhua had received the information that he had passed the preliminaries for the Knife Forging Competition. The information also mentioned specific information such as the date and location of the competition.

This also allowed him to have one less thing to worry about after receiving the news. He had nearly three months of free time, which also allowed him to devote his mind to subsequent plans.

In the week since he came back, he has not been idle. He usually works in the blacksmith shop, makes farm tools, and helps his neighbors repair farm tools. Of course, he has not given up on building motorcycles.

Everything in this work starts with the engine, the heart of the motorcycle.

Li Zhenhua has collected all types of engines, and he has also generated drawings of all engines bit by bit.

With the help of his analytical eye, he also determined the type of engine to be used in this motorcycle.

Star engine, yes, he chose the radial engine,

With the development of motorcycles now, engines have actually become very mature. It can be said that the engines on mass-produced motorcycles are the most suitable for motorcycles.

But this does not mean that changes cannot be made. After choosing, he found that radial engines and rotary engines are also very suitable for use in motorcycles.

Why choose a new engine? Of course, the life of the rotary engine is too short, and the metal materials he currently has cannot satisfy the requirements of the rotary engine.

Therefore, the radial engine was his first choice. This engine is very reliable and does not require a gearbox.

Li Zhenhua has already thought about it during this period. The clutch on the motorcycle will still be retained.

This is used to cut off the power output and will not keep the motorcycle in power output mode.

As for the gears of the motorcycle, it doesn't matter if it doesn't or it does. Anyway, the whole car has only one gear. The speed of the motorcycle is controlled by the throttle on the right hand.

The throttle has also been individually designed, and the handlebar has been designed with an exposed gear. This design was modified to allow the car to have a cruise control function.

Radial engines are actually divided into two sub-types, one is called a rotary cylinder engine and the other is a fixed cylinder engine.

This time he used a fixed-cylinder engine plan. He thought carefully about the rotary-cylinder engine. The cylinder is always rotating.

When passing through poor road conditions, the engine will inevitably be damaged.

For safety reasons, it is better to protect the engine, so the rotating cylinder engine solution is excluded.

This time, in his manufacturing plan, he chose to build two types of motorcycles, one with five cylinders and the other with seven cylinders, as two displacement options for motorcycles.

For a five-cylinder engine, the displacement of one cylinder is 90cc, and the five cylinders combined are 450cc.

As for the seven-cylinder engine, each cylinder has 10cc more than the five-cylinder engine. The entire displacement of the seven-cylinder engine is 700cc.

The two engines can provide 71 horsepower and 111 horsepower respectively, which can be said to be very powerful.

As for how the two engines were developed, it was of course a result of trial and error with the help of three major plug-ins: the virtual laboratory, the analytical eye, and the ingenuity.

It can be said that the whole process was very arduous. If the engine trial-produced in the laboratory was spread out flat, two football fields would not be able to fit in it.

If the research and development process were put into practice, the cost of research and development would probably exceed 100 million, or even exceed 1 billion.

Don’t forget the research and development expenses of the three-cylinder Junqi, which is said to have cost 19 billion. Although that money was spent, if you want the engine to be stable, just lift the cover to increase the idle speed.

Under his design, the appearance of this motorcycle is not much different from traditional motorcycles.

If we want to talk about the difference, it is just that the engine under the fuel tank is larger than the ordinary engine.

The model did not choose compact racing cars and street cars, but chose relatively large cruisers.

From the engine to the entire vehicle, the design of the entire vehicle can be said to be very domineering.
