Siheyuan: Heavy Industry Revitalizes the Country

“This car has huge potential, and there are many areas for improvement.

And it’s not difficult and can be changed now.

However, this car also has some major flaws.

In my opinion, it is barely usable, but still some distance away from being fully usable. "

After looking at the drawings, Fang Xiang thought for a long time.

He still has many car drawings in his mind.

Instead of leaving it alone, it is better to use it to contribute to the country.

Although the domestic technology is still very backward.

But this BJ212 is not something high-end.

Especially since this is for supplying the troops, the materials can just be made thicker without being too particular.

However, there is still a lot of room for improvement in many details and small places.

And, take the long view.

Instead of always being forced to design guns, it would be better to take the initiative to design car engines.

At least it is a leap forward. As long as guns are finalized, production can begin.

There will most likely be no major changes for decades.

At most it's just a minor repair, which can be done by any engineer of comparable level.

If I stay in this field, it will be a complete waste of time.

But car engines are different.

From cars to SUVs to trucks, vans and motorcycles, the application range is too wide.

Not to mention the prospects.

For many years to come, automobiles will be an indispensable basic industry for a country.

Especially after the 21st century, alternative real estate has gradually emerged.

It is becoming a pillar industry.

Going further up, there are more advanced airplanes, rockets, and missiles, and you will have the opportunity to slowly get in touch with them.

So, just take on this task directly.

Just think of it as paving the way for the future.

"Wow, you're quite arrogant!

Do you know how many experts and engineers designed this?

How come you can only be considered passing?"

When Professor Xu heard what Fang Xiang said, he immediately became dissatisfied.

What he said sounded like criticism of Fang Xiang, but the underlying meaning was actually a reminder and a caring one.

I was worried that Fang Xiang was too young and might say something offensive.

"Hey! Lao Xu, keep quiet. I want to see what else this kid can pull out of his pocket!"

However, Mr. Hu waved his hand and looked at Fang Xiang with a smile.

Mr. Hu understood Professor Xu's thoughts as soon as he heard them.

But Mr. Hu's cognition was refreshed again and again.

Naturally, I have to find out Fang Xiang’s past.

"It's okay, Xiao Fang, if you have any ideas, just tell me directly.

Everyone here is your family and your elders.

Without outsiders, even if something is said wrong, it won’t get out.”

Old Liu still had that smiling, harmless look on his face.

It sounds like high-sounding words, but in fact, they are also trying to trick Fang Xiang.

When Fang Xiang heard this, he immediately laughed. How could I not understand what was said?

Isn't it just to see if we have the real stuff?

“The suspension here, if you use a double-jointed arm steering tie rod.

Here, add a sway bar.

Here, change the mounting direction of the rear shock absorber.

It can solve the problem of rapid turning, sideslipping and tail drifting.

Or just replace it with a torsion bar spring.

This way the energy storage capacity is several times higher, the weight is light, the structure is not complicated, and no lubrication is required.

More importantly, not only does it save materials, it can also adjust the height of the vehicle body, and the cost is not much higher.

Here, the engine's fuel supply system and ignition system.

It can be upgraded, that is, the carburetor and spark plugs.

It can not only reduce exhaust emissions, but also improve combustion efficiency and reduce fuel consumption.

Then there is the engine construction, the power and structure are not very good.

There is a lot of potential for optimization. I think we can improve the power in any way we can.

At the same time, it can not only reduce fuel consumption, but also reduce noise, and acceleration will be further improved.

And the car doors, why not change it to a four-door?

The chassis is lengthened and the structural strength is improved.

Not to mention that it can carry more people and goods, even if a hook is added, it can also tow more heavy objects.

Here, the air intake system can be improved, so that the wading height can be at least 1.5 meters, not to mention 1.3 meters.

And here, what era is it now, why not use a dual-circuit hydraulic braking system?

This increases the redundancy of the braking system.

Here too, a pulley parking brake system can be used.

The combination of these two can at least increase the transmission efficiency by half, no, at least double it!

And here, why is the front windshield made of two small pieces?

Wouldn't it be better to use a large integrated glass? It is also convenient to install and replace.

It can also avoid motion sickness.

Then here, I see that the tires are all off-road tires.

If you drive in the city, you can reduce fuel consumption by changing to radial tires.

And here, can we get rid of this auxiliary fuel tank?

After the chassis is lengthened, the capacity of the fuel tank can be increased accordingly.

The auxiliary fuel tank is inside the car. Don’t you consider the safety factor at all?

Finally, you can add a rearview mirror, it will be much more convenient. "

Fang Xiang was not polite at all and started talking about the drawings.

After the first few sentences, Professor Xu, Mr. Hu and Mr. Liu just nodded.

The further they got to the end, the more shocked they became.

Even after Fang Xiang finished speaking, the three of them had not yet recovered from the shock.

He stared blankly at the place that Fang Xiang had circled on the drawing.

"The disciple surpasses the master, and the waves behind push the waves ahead.

You can’t refuse to accept your old age.”

Professor Xu reacted the fastest and burst into laughter.

Old Hu and Old Liu were still staring at each other.

After waiting for a long time, Old Liu nodded to Old Hu.

"Xiao Fang, how about you go to the Beijing Automotive Manufacturing Plant and stay there for a while?

Just do me, the old man, a favor.

Put into practice all the things you just mentioned."

Mr. Hu lit a cigarette, calmed himself down, and then spoke.

"Mr. Hu, this is embarrassing for you, isn't it?

I can talk about it on paper, but I am still too early to actually put it into practice.

Besides, these places have been drawn.

Just change it and it's done."

Fang wanted to wave his hands quickly. He didn't want to encounter the same situation as before with the Ministry of Machine Building.

Being surrounded by a group of people and then questioned.

Having experienced this once, I don't want to experience it again.

"Hey! You kid!"

Mr. Hu immediately became unhappy, glared at him and started blowing his beard.

"Ahem.

How about this, I'll give you an idea and let you guys see what you think.

Let Xiaofang take this drawing back.

Then I'll draw another one and give it to you.

Is this okay?"

When Professor Xu saw that Mr. Hu was about to lose his temper, he coughed immediately.

Come up with a solution.

When Mr. Hu heard this, he was silent for a while, but thought about it for a while.

“It’s not impossible, but it has to be quick.

The prototype has been under testing for more than a month.

If it’s too late, when it comes to the review stage and I report to the General Staff, I’m afraid it will be too late.”

After taking the last puff of his cigarette, Mr. Hu put it out and looked at Fang Xiang.

"Not really. I think it won't be finalized so soon, at least within this year.

Maybe we’ll have to wait until next year.”

Professor Xu shook his head, as if he knew something.

"Okay, then you can take these drawings away.

If the suggestions you made are indeed effective.

The promotion is as much as you said, I will give you credit!"

Mr. Hu didn't ask any more questions. He knew very well that Professor Xu had some channels that even he couldn't reach.

I agreed immediately and decisively.

“It would be best if it could be drawn before June.

This way, maybe we can produce a few prototypes before National Day. . . . . . "

At this time, Lao Liu suddenly interrupted.

They understood immediately and looked at each other.

"Before May, I am willing to issue a military order!"

Fang Xiang stood up immediately and raised his right hand above his head.
