Find hope in despair and remain optimistic in pessimism. This is probably a portrayal of An Ning's mentality before he met Li Fanyu.

As a person who is well aware of the vast and extensive system of the automobile industry, she has always thought that she is destined to take a long road full of fog.

The purpose of establishing the laboratory is to incubate an excellent design team and provide a hotbed for independent engine research and development.

According to her expectations, if this can be achieved in five years, it will be good.

But the appearance of this guy in front of him has shortened the process too much. This sudden happiness, how could she not be surging.

However, looking at Li Fanyu with a breezy face, she was a little depressed, and wanted to say something, but swallowed it back.

I was obviously extremely excited, this guy was so calm. He doesn't know what emotions to use to deal with the current situation, doesn't he know that he has made history and is known as the first person in the field of national automobile engines?

The surging belly couldn't find a catharsis point, so she had to sigh, "Brother, aren't you excited?"

Li Fanyu yawned, tilted his head to look at her, and said, "What are you excited about?"

"You have designed the first car engine in China!" An Ning glanced at him, and he couldn't suppress the excitement in his heart.

"Ah," Li Fan was stunned, he was patronizing Professor Zhang just now, and he didn't have time to think about this question.

He pondered it for a moment, and then sadly found that he couldn't get excited.

Because I have known for a long time that this thing will work, I did this test in line with the higher-level mentality of making a perfect product.

How can I say it, it's like you've watched an adventure movie beforehand, and you know the ending and all the plot points. Then, I accompanied my friends to re-watch the second week, and I can't spoil it.

This egg hurts, you can feel it.

And at this moment, his eyes flashed, and the peace with his face crimson was in his eyes, and he was a friend who watched this adventure film for the first time......

Looking at An Ning's annoyed expression, he quickly put away his caring expression, raised his hand weakly, and said with a paralyzed face: "Yay... I'm so happy... I am the father of autonomous engines......"

Huh? The father of autonomous engines? I'm a little excited about this title!

"Sister, since I'm so powerful, why don't you reward me with a loving hug!"

Witnessing the birth of the first engine has been expected many times in An Ning's heart. She thought she would cry, laugh, and even get drunk, but she didn't expect to be like this... I want to beat someone.

An Ning smiled charmingly and stretched out her arms.

Li Fanyu immediately hugged him when he saw the situation, but was deftly dodged by An Ning.

"You can't tell if you're naïve or old. Forget it, I don't want to bother you. ”

An Ning gave Li Fanyu a big roll of his eyes, turned his head and sat down in front of the computer, and entered the test data of the engine into the database.

Li Fanyu's egg hurts, and it is inadvertently disgusting. Therefore, how important is a good acting act.

He slammed into front of An Ning, "Sister Ning, don't you think about rewarding me?"

An Ning didn't raise his head, "Why did you go when I was excited just now, now I'm not in the mood, get away from my sister." ”

"Sister, your mood has changed too quickly."

"A woman's heart, the clouds in the sky, change when she says it. You've never heard of that?"

Li Fan scratched his head in annoyance, raised his head suddenly, and said proudly: "If you don't give it, you won't give it, and you will be more excited in the future." The engine is an egg, and the sea of stars is my direction!"

At this moment, his body seemed to radiate a dazzling light, making An Ning lose his mind for a moment.

But she immediately came back to her senses and teased, "Heh... Dear brother, you missed out on a once-in-a-lifetime reward, no matter what you may say. And I don't think you should think about the sea of stars, let's make the road run first. ”

Royal Sister Ning caused 10,000 points of damage to Li Fanyu.

Looking at Li Fanyu's dejected appearance, An Ning snickered in his heart. "By the way, let's give the engine a name, it can't be done without a name code when calibrating and declaring. ”

Li Fanyu thought about it and worked hard to overcome his incompetence in naming. The last slap on the thigh: "Let's call it zgx888." ”

An Ning raised her head and frowned, "Does it have any special meaning?"

"The engine is the heart of the car, and ZGX is the meaning of the heart of China.

......

Ren Anning would not know if he wanted to break his head, this code name originated from the ringtone of Lao Zhang's slag mobile phone, and the code number of EA888, which has never appeared in this world.

As a result, China's first independent engine has such a name.

In the following time, An Ning and Li Fanyu plunged headlong into the sea of testing, and started various complicated test work on ZGX888 without sleep.

Because the engine is completely copied from the EA888 in the mass production stage, it almost crushed the customs clearance.

This feeling is like being a top student in college doing the arithmetic exam paper of the second grade of elementary school. Such a pleasant and dripping sense of smoothness made An Ning think that he was debugging the test equipment, not the engine.

In just three days, the ZGX888 passed all the test items. This also means that it is about to enter the next link - calibration.

Calibration is to set standards.

But what is a standard for an engine? A standard is not a cold value, it's a variable.

For example, this engine, at what revolutions can it get the highest power, at what temperature can it exert the maximum performance, what is the maximum temperature and minimum temperature that it can tolerate, what are the operating parameters of the engine on the plateau, what is the balance of each cylinder in various environments, and what is the range of noise at each revolution...... And so on and so forth, and so on.

So, why do such complicated things inside?

Because the engine is also a part of the car, it must be subordinated to the overall situation of the whole vehicle operation. As mentioned earlier, the engine is the heart of the car. But there's also a brain in the car -- the ECU, the electronic control unit. That is, the legendary trip computer.

It regulates key parts of the vehicle to achieve the best and most appropriate performance in all situations. It will continuously collect sensor information from various parts of the vehicle for calculation, and then control the ignition, air-fuel ratio, idling, waste and recycling of the engine and other parameters.

But this brain is very rudimentary, and it doesn't automatically recognize road conditions. For example, he won't say, "I'm wiping, there's a pit in front of you!" Engine, brother, let's get more horsepower and get over! Or, damn it's boring in traffic, let's turn off the engine.

What it can do is to adjust the parameters calibrated by the engine according to the owner's human intervention.

For example, if the owner chooses the economic mode, then wow, let's reduce the performance parameters of the engine and spray less oil.

However, this ECU, how does it know in what state the engine is the most fuel-efficient?

By calibration.
