In two days, the three of them visited the car show for three consecutive days. Except for the first day, they 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 carbon deposits in the exhaust pipe are serious, whether the oil nozzle is smooth...

A few people stayed until the end of the auto show. Of course, there was nothing gained 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 what he gained on the first day. As for what he gained on the second day, I won’t go into the specific details. Anyway, none of the three people watching the auto show went back to Guo Shugui’s villa that day, and even Li Zhenhua slept in the hotel.

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

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

Why is it the third day? Because their trip these past few days was too busy, so 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, why don't you just wait until we get home and make a trip to Wang Mei?

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. Among 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 a 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 the old 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 it had been a week 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 stated 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 from 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 used in 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 did he choose a new type of 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 the 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 block 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, one with five cylinders and one with seven cylinders, as two displacement options for motorcycles.

five-cylinder engine,,,

As for the seven-cylinder model,,.

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 that was trial-produced in the laboratory was laid out flat, it would not fit in two football fields.

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 a relatively large cruiser.
