Start with a blacksmith shop.

Thinking about the types of these engines, he began to search his mind for representative car models with these engines, otherwise he wouldn't know where to find these engines.

We don't need to worry about the radial engine anymore; we've already found a prototype on the aircraft.

Next is the L-type engine, which is essentially an inline cylinder engine, typically with a maximum of six cylinders.

If the number of cylinders were higher, the resulting engine would be too long and unsuitable for use as a car engine, since there isn't enough space to house it.

This type of engine is easy to find; most ordinary cars use this type.

There's also the horizontally opposed engine, which is actually a variant of the V-type engine.

The pistons are evenly distributed on both sides of the crankshaft, and their main feature is that they can reduce vehicle vibration during driving.

It can also lower the car's center of gravity, making the car more stable. However, there are also disadvantages.

Uneven cylinder wear is the biggest drawback. If the engine runs long enough and the uneven wear becomes severe enough, oil burning is also a serious problem for this type of engine.

The representative models are easy to find: Six Star brand cars and Porsche's 911.

A V-type engine is easy to understand; it's an engine with two groups of cylinders arranged in a V-shape.

The advantage of this type of mechanism is its small height and length, making it easy to install on a vehicle.

The downside is that its complex structure makes it inconvenient to maintain and repair. However, it's easy to find representative models; you can get this engine from any Mercedes-Benz or BMW.

Another type is the W-type engine, which is a variant based on the V-type engine. It can be seen as two V-type engines combined together.

This type of engine is not commonly used; it is mostly found in high-end models, such as the Passat with the lettering.

There is also a niche rotary engine, which has only been used in Mazda vehicles from Japan.

Slowly, Li Zhenhua recalled all this knowledge, and then a difficulty arose again.

Some car models with certain motives are easy to find, but others are not, such as the V-shaped four-ring design.

Thinking about this, he couldn't help but become curious, wondering what was so difficult to use in Guo Shugui's pants!

He acted on his idea immediately, and a hooded vehicle materialized in his mind. He eagerly opened the hatch, and there it was, with the word "V12" on the engine cover.

"Alright, we've missed another motive. It really was a long and arduous search!"

With the two types of motivations ruled out, only three types remain to be collected: vertical, horizontally opposed, and W-shaped.

As for the least popular type, the rotary engine, which also has the highest RPM, smallest size, lightest weight, and is most suitable for motorcycles, it's best to find it, but there's no regret if you can't.

For the other three types, the W-shape and the horizontally opposed one, we'll probably need Guo Shugui's help.

Thinking about all this, and then seeing the rickshaw in front of him, Li Zhenhua was tempted.

Everything else is secondary; the most important thing now is to dismantle the two existing engines and generate the blueprints.

Without much thought, he launched an attack on the engine compartment that Curry had already opened.

The process of removing the engine from the car was not smooth, and many times Li Zhenhua did not know where to remove it.

But is this a problem for him? It's not a problem at all.

You should know that when the repair shop was dismantling the car, the mechanics there...

They're the ones responsible for repairing cars; it's impossible that they didn't fix the car properly and then added more problems.

But Li Zhenhua was different. He wasn't afraid of causing any damage to the car, and he resorted to violence for parts that he couldn't disassemble.

Forced demolition is still quite effective; sometimes, after using force, one can study the situation and discover the correct method.

This is where the virtual lab comes in handy. One of its most important functions is refresh and visualization. It's just a matter of re-visualizing a lab; there's nothing difficult about it.

As he disassembled and studied the parts, Li Zhenhua, despite the bumps and knocks, managed to remove the engine and gearbox completely.

Looking at the powertrain in front of him, he felt very proud, and all the time he had spent was worthwhile.

With the engine in place, he can directly visualize the powertrain when he needs it again, which is very convenient.

Li Zhenhua silently chanted "refresh" in his mind, and the originally messy room was immediately transformed into a spotless space where he was the only person present.

With one engine sorted out, the next step for him was to dismantle the aircraft—an old plane from World War II.

Following the same steps and operations as when disassembling the car before, through his tireless efforts, he finally disassembled a complete 7-cylinder radial engine.

He could finally rest for a while. After all that trouble, he had obtained two engines, which would later become the prototypes for his research on motorcycle engines.

"Knock knock knock..."

As he stared blankly at the two engines, the sounds from the outside world came through the laboratory again.

He knew it must be Liu Xiaodong or Guo Shugui knocking on his door, so he stepped out of the lab, opened his eyes, got out of bed, and opened the door.

Guo Shugui was standing at the door, looking at him with a curious expression.

"Hua Zi, you went back to your room as soon as I got back. Are you alright?"

"It's okay, don't worry about me. I was just too tense before, and now I'm just a little tired."

Upon hearing this answer, Guo Shugui felt a great weight lifted from his heart.

"I'm thinking of going to the auto show this afternoon. Do you want to come? My husband finally lifted my travel ban, and I want to buy a new car!"

Looking at Guo Shugui with surprise, Li Zhenhua thought his behavior was just showing off. His ban had just been lifted, and now he wanted to buy a car.

"Aren't you getting a little too cocky? Your dad just lifted the ban on you, and you already want to buy a car and go racing?"

"No, that's not it. I just want to go to the auto show to see the pretty girls and check out the cars while I'm at it. I'll only buy a car that I like, and if I don't like one, I won't buy it!"

Li Zhenhua suddenly realized that Guo Shugui probably wasn't there to look at cars; he was there to see young women.

"Looking at pretty girls is your real purpose, isn't it? Fine, after getting to know you recently, I thought you were a well-behaved rich kid..."

But I never expected you to reveal this now; it turns out you're the repressed, secretly passionate type!

Guo Shugui looked at Li Zhenhua calmly and answered him without changing his expression:

"So what? I paid, the girls got a good deal, and I got physical satisfaction."

Is it wrong to have a friendly exchange of soul and body with a pretty girl?

Also, I just asked Fatty, and he's going this afternoon too.

Are you going? I'll lend you both a high-end camera each.

Let me tell you, these girls have a sharp eye! They can tell if you're a good date just by looking at your camera!

These words truly broadened his knowledge.

He was also thinking that it was perfect timing, as he needed to collect the remaining engine types anyway.

"Okay, wow, I've learned something new from you. It seems like my strange knowledge has increased quite a bit!"
