Chapter 52: Still want to make things difficult for me?
Fang Xiang stood at the gate of the First Ministry of Machine Building, a little dazed.
He really didn't expect that the First Ministry of Machine Building would act so quickly.
I thought it would be difficult to ask for leave, so I would delay it for a few days.
Unexpectedly, Yin Qingqiu called his father that night.
On Monday, the Ministry of Machinery sent Shuimu a secondment letter.
When counselor Mr. Zhang called Fang Xiang over, there was a strange expression on his face.
Of course, it’s not his fault.
There are quite a few units across the country that have issued secondment letters.
Either second a teacher or second a professor.
But this was the first time he had seen a student on secondment.
I could have refused, but when the counselor called Professor Xu for his opinion.
Professor Xu actually agreed and said that all the benefits would be given to him.
So Fang Xiang had no choice but to come.
Fortunately, what Director Yin had agreed upon before has not changed.
Secretary Huang was already waiting at the gate of the Ministry of First Machine Building.
"Mr. Fang, we've finally got you here. Please come this way."
Looking at Huang Mi's smile which was obviously forced on purpose.
Fang Xiang was speechless. Even if he was pretending, it was at least better than last time.
If this had been done earlier, there wouldn’t have been so many troubles later.
He curled his lips and followed Secretary Huang into the office building.
This time, not only Director Yin was waiting for him, but also several middle-aged and elderly people who were obviously technical people.
They all wore Zhongshan suits and glasses.
The look in his eyes when he looked at Fang Xiang revealed deep suspicion.
Fortunately, there were no questioning voices.
Fang Xiang had no intention of arguing with them.
It’s the same design as last time.
Fang wanted to repeat the places he had marked last time.
Under Director Yin’s stern gaze.
All the engineers present kept their mouths shut.
He took out his notebook and wrote down Fang Xiang's words word for word.
But soon, when Fang Xiang finished speaking.
The expressions on the faces of these engineers changed.
"Um... Mr. Fang, I want to ask you something."
There was a youngest engineer who looked a little guilty.
But I still mustered up the courage and raised my hand like a primary school student.
"I don't deserve it. If you have any questions, just tell me."
Fang Xiang just took a sip of the tea that Secretary Huang handed to him.
When I saw someone asking a question, I quickly put down my teacup.
“Just now you said that the crankshaft is not strong enough and will deform.
We did encounter this problem. Is it the only option to replace it with steel? "
The engineer pushed his glasses up, his eyes filled with doubt and cunning.
“Actually, I encountered this problem the day before yesterday in my research group at Mizuki University.
The initial judgment is that it is a problem of craftsmanship and materials. But in my opinion, it is actually a problem.
Because the current domestic steel smelting level is insufficient, when the accessories are cast into shape.
There are still a lot of impurities and bubbles left in it, resulting in insufficient strength.
If there is enough load margin, there is no problem in using it.
However, once the load is too large and exceeds the threshold, deformation and fracture will occur.
Is it necessary to ask such a simple question? "
Fang Xiang naturally saw the look in his eyes, which was to ask technical questions to see if he had the ability.
Or maybe he wanted to see if he was guessing.
If nothing unexpected happens, the next question will be more intense.
“I also have a question. You said that the intake manifold and intake duct are not designed properly.
This results in insufficient air intake, which directly affects engine heat dissipation and fuel consumption.
Is there a better solution to this problem?"
Sure enough, an engineer who looked older asked a more difficult question.
“If I remember correctly, this V8 engine was originally from Cadillac, right?
You only copied the engine design, why don't you take a look at the operating environment of the engine compartment?
How long is the front of a Cadillac? How wide is it? How big is the grille?
How much heat dissipation space is reserved near the engine?
Have you compared the new Hongqi models you designed?
Taking a step back, how much oil does the United States produce? How much oil do we produce?
The United States is suitable for this kind of high-horsepower and multi-cylinder environment. It doesn't care about the fuel consumption.
Do we have such an environment in our country? Can we not care about fuel consumption?"
Fang Xiang did not directly give a solution, but directly denied their design from the side.
As soon as these words were spoken, several engineers present broke out in sweat.
Originally, they were pulled here to listen to a college student say that there were problems with their design.
There is already a lot of resistance.
Even Director Yin had done a lot of work for them in advance.
When they saw Fang Xiang for the first time, he was just 18 years old as a freshman.
The dissatisfaction in my heart immediately reached its peak.
Even Fang wanted to reiterate the problems on the drawings.
They still haven't gotten over the mentality of looking down on others.
There is even a kind of, are you qualified to tell us these thoughts?
The first problem is that they were just appetizers.
Look at this college student and see if he understands it or not.
The second question is to see whether he was guessing.
But no matter how much I planned, I never expected this.
This Fang Xiang directly and fundamentally negated the design drawings that they had spent two years drawing.
And what they said makes a lot of sense.
Because they really didn't think about these issues.
In modern terms, all they did before was dissect, draw, and then copy and paste.
But what they didn't expect was that it was so simple to copy and paste.
All kinds of unexpected problems occurred.
And the people who drew the picture didn't know where the problem lay at all.
"So what Mr. Fang meant by this is that this picture is useless?"
Director Yin is not a professional, he is just an administrator.
But day after day I've been hanging out with these technical people.
I have more or less understood some professional terms and can roughly understand their meaning.
Naturally, I thought of the same question as these engineers.
I was afraid that the worst would happen. After two years of work, the design was fundamentally wrong.
“That’s not the case, but this engine definitely can’t be used like this.
First of all, there must be major changes, but the only question is how to make them.
It also depends on the other various parameters of the new Hongqi.
For example, data on transmission system, chassis system, body system, electrical equipment, etc.
Just because a car has more horsepower doesn’t necessarily mean it’s good.”
Fang Xiang sighed, looked at Director Yin with a serious face, and expressed his thoughts.
“If you just want to use it simply as a power system.
So there should be no problem in adjusting, modifying and optimizing this engine.
However, the mismatch with the entire vehicle will certainly bring about diverse problems.
The first and most obvious thing is fuel consumption and serviceability.
The biggest problem at the moment is the inadequate processing accuracy and assembly process.”
Judging from Director Yin's expression, it was obvious that he didn't understand, so Fang Xiang simply changed the wording to a simpler one.
"Bring me the design drawings of the whole vehicle."
Director Yin now understood and immediately asked Secretary Huang to get the design drawings.
“If I remember correctly, the prototype was a reference Chrysler.
Chrysler cars weigh more than two tons, and Cadillac is about the same.
The prototype engine has a power of 300 horsepower.
The new Hongqi weighs more than three tons and has only 220 horsepower.
So, this car is not designed for mass production, right? "
When the data of the entire vehicle was placed in front of Fang Xiang, Fang Xiang discovered another problem.
"That's true. They are produced mostly for leaders to use and to entertain foreign guests."
Chief Yoon nodded, acknowledging this.
"If it's just for small-scale production, it's okay to copy it.
Uh... I mean copying it verbatim is acceptable.
Although the power was lost by nearly one-third.
But I guess you are definitely unwilling to give up and want to do better, right?"
Fang Xiang had just said the word "shanzhai" when he suddenly remembered that this word did not exist in this era. He immediately changed his words.
"Student Fang, you are absolutely right. Do you have a solution?"
