Siheyuan: Heavy Industry Revitalizes the Country

"You came just in time. I just said I was going to call you."

When Professor Xu saw Fang Xiang pushing the door open, he smiled happily and waved.

"What's the matter?

I just returned to Beijing, you are not going to assign me any more work, are you?"

Fang Xiang was stunned and shivered for no apparent reason.

"clever!

Yesterday, Luoyi First Tractor Co., Ltd. made a phone call and they plan to develop new light walk-behind tractors and medium-sized tractors.

As for the engine, I'll leave it to you.

Here, these are the parameters they require, take a look.”

Professor Xu held up a piece of manuscript paper and shook it at Fang Xiang.

"No! I've only been drawing for over a month.

I painted in Shaanxi, I painted in Luoyi, why do I have to paint again when I return to Beijing... "

Fang Xiang suddenly felt a little resentful.

"What are you talking about!

I paint for you because I respect you! Don't give me the nagging!"

Professor Xu's face suddenly turned stern.

"What's going on, Professor? I've never seen you so angry before. Who pissed you off today?"

When Fang Xiang saw Professor Xu's expression change, he immediately picked up the thermos and refilled the teacup in front of Professor Xu with water.

While pouring water, he turned his head and glanced at Qin Jun.

Unexpectedly, Qin Jun made a face at him.

Fang Xiang suddenly felt much more at ease.

"That's good, but right now, nothing has been decided, so just work hard and wait!"

Professor Xu felt helpless when he saw Fang Xiang's deliberately forced smile.

Professor Xu knows this beloved disciple best.

He doesn't have any bad intentions, but he is quite petty.

Also, people are getting smarter nowadays and not as easy to cheat as before.

"What's the good news?"

Fang Xiang immediately moved the bench over and sat next to Professor Xu.

"Can you change this bad habit of wanting benefits in everything you do?"

Professor Xu looked very disappointed and tapped the table heavily with his finger.

"Hey, Professor, you know how many times I have been driven around in these years.

If I don't give you some benefits, people who don't know me would think I'm cheap labor.

Just yesterday, I returned to Beijing, and Mr. Hu arranged several things for me.

But no benefits were mentioned.

Tell me, how many times have you cheated me since you met Mr. Hu? "

Fang Xiang's eyes rolled and he immediately started to complain about his grievances.

"Don't give me that. No matter how unkind Old Hu is, he's not that kind of person.

What's missing from the benefits others give you?

You! You are pushing your luck!"

Professor Xu didn't buy Fang Xiang's trick and immediately blocked him back.

"Okay, stop complaining to me.

Your good points are inevitable. I guess you will know them when you get married."

Professor Xu seemed to be scolding Fang Xiang, but his words still showed his care and concern.

"Hey! These are the requirements and standards for a first-class trailer. I leave it to you.

We need to hurry up and get it done, as this year's scientific research funding is significantly short.

Once this matter is resolved, I can get a lot of funding, and I can breathe a sigh of relief."

Before Fang Xiang could speak, Professor Xu pushed the manuscript paper in front of Fang Xiang.

"I'll take a look."

As soon as Fang Xiang heard Professor Xu mention scientific research funding, he immediately understood what was going on.

In theory, Professor Xu’s projects and scientific research are funded by the state.

However, the state’s funding is fixed, and there are very detailed requirements on what kind of work to do with what money.

Professor Xu is also a person who cares about talents. When he sees good seedlings, he will think about teaching them more and guiding them more.

So inevitably, I set up several scientific research teams under me.

However, the country’s money cannot be spent indiscriminately, and only a few people can get the country’s money.

Other scientific research groups rely on professors to carry out research and development with some cooperating enterprises.

In this way, companies can shorten R&D time and reduce costs.

Professor Xu can get some financial support to support some non-staff scientific research teams.

Cao Tianwei and Fang Xiang were among them.

Now that Fang Xiang is able to stand on his own, it is only natural for him to do these things to give back to Professor Xu and other fellow students.

Soon, I finished reading all the requirements and standards on the manuscript paper.

Simply put, what is needed is stable, fuel-efficient and reliable single-cylinder and four-cylinder diesel engines.

The overall parameters and standards are higher than the two-cylinder diesel engine of the last Dongfanghong tractor.

After all, it is a new model, so it is normal to have higher and newer requirements.

For others, it may be a very troublesome thing and require making two designs.

But in Fang Xiang's eyes, all he needed to do was make an engine.

Because that's what BMW did later, it made a four-cylinder engine.

Based on this four-cylinder engine, it can be increased to six cylinders, eight cylinders, and even later one cylinder was cut off to become a three-cylinder engine.

So taking this example, Fang Xiang only needs to design a single-cylinder engine.

Then, according to needs, add one cylinder to make it a double cylinder, or add three cylinders to make it a quad cylinder.

If YTO plans to produce heavy-duty tractors in the future, it can continue to add two cylinders to make it six cylinders.

This model is collectively referred to as standard modular production in the industrial field.

Just like playing with Lego, just copy and paste.

Sounds simple?

But in fact, it is a very difficult thing to do.

Not to mention anything else, the standards for fuel supply, fuel injection, heat dissipation and other outer accessories of the engine are different.

The internal structure will naturally not be exactly the same.

But no matter what, it is still simpler and more economical than designing and producing separately.

However, the difficulty is only for other people. They think it is really like building Legos.

“This is not difficult. Give me a month and I will make a complete set of modular engine drawings.

In this way, within 20 years, there should not be much demand for engines. "

Fang Xiang calculated the workload and immediately nodded in agreement.

"Modular?"

This is not the first time that Professor Xu has heard this term. After all, modularization appeared in industry as early as the last century.

But in this era, Fang Xiang was the first person to propose the use of modular concept to make engines.

“对，就是简单的1+1等于2，2+2等于4，2+2+2等于6。

It’s very simple.”

Fang Xiang thought Professor Xu didn't understand, so he gave a brief explanation.

"Simple as you are!

The accessories, strength, precision, working environment and production process required for single-cylinder, double-cylinder and four-cylinder engines are very different.

You thought it was a toy!"

After all, Professor Xu was limited by the times, although he thought of the benefits of modularization at the first time.

But no matter what, Professor Xu is an expert in the field of mechanics, and he can guess the difficulty brought about by modularization even if he uses his butt to think.

Suddenly he became anxious and started tapping Fang Xiang with the tip of his pen.

"Don't be impatient, this modularization is actually just a layer of window paper.

You will understand it clearly when I draw the picture later. Besides, there are many benefits of modularization.

Even if it means producing a production line yourself, it is worth it.

Later, Second Automobile can also use it, why don't you believe me?"

Fang Xiang shrank his neck, touched the place where he was hit, and pretended to be aggrieved again.
