Chapter 554: Confusion

"Don't say polite words," Zhang Zongjun interrupted Xie Fei who was about to say some polite words to himself, and took Xie Fei's hand, such good news made Zhang Zongjun not care about the demeanor of the general manager at all, "Go, go, Xie Gong, take me to see." ”

Zhang Zongjun is very anxious, the power of ceramics, an ancient material from China, he has seen it in the composite ceramic brake system, the profit and effect make him feel a little unbelievable when he thinks about it now, so what does a more advanced ceramic engine look like? Now he can't wait to see how the engine performs. How far can it go? Xie Fei's phone call made Zhang Zongjun's heart feel like a kitten was gently scratching on the tip of his heart with its little paws, itching and sultry.

Xie Fei nodded, the boss's mood, he could understand that when he made this baby, although he had already let himself know what the result would be through calculations before, but when the real sample was made and placed in front of him, he was not excited to hug his colleagues like a child and cry and laugh?

As the group walked briskly to the lab, several engineers were testing a machine attached to a strange metal shelf. \\\\

In Zhang Lan's opinion, the volume of this machine is not large, and it looks about the same size as a twin-cylinder motorcycle engine with a displacement of 250 ml.

The machine is running, and there are more than N pipelines of various colors connected to it, and next to the pipeline is a set of instruments that look very complex, which shows some curves and other things like this engine, which should be used to test the performance of the engine and the strength and reliability of the engine components.

There are several other engineers who record the data displayed together after the previous engineer has tested the engine. Judging from the excited and somewhat reddened expressions on the faces of several people, they should be very satisfied with this engine. Those who are satisfied cannot be more satisfied.

Although the engine is running. But there was almost no vibration in the engine, and the operation was very smooth, Zhang Lan even found a ceramic cup full of water on the engine, but the amazing thing is that the water cup did not shake at all. It's just that the water in the cup gently ripples, but this alone shows how smoothly the engine is running. \//\

And if you listen closely, the operating noise of the engine is not very loud, just like the noise effect of a small gasoline engine with a well-effected silencer, only the slight sound of the engine running, that feeling. It's like the sound of the wind blowing in your ears. Even for testing occasionally, the throttle was raised. The noise has increased, but it is just like the wind is blowing through your ears a little stronger. According to Zhang Lan's own guess. Now the noise of this engine will not exceed 55 decibels, it should be between 45 decibels and 50 decibels.

Although it is not yet known how the performance index of the engine, including power and torque, will perform. But just this ability to control engine noise is enough to make many people embarrassed. The material advantage of the ceramic engine is evident at this moment: even in a completely enclosed space in the research room, where the sound can be generated countless times, the engine noise is so low. So can you imagine what it would be like for a car equipped with this engine to be on the open road outside?

It should be like a gust of wind passing by people, and the air flow brought by the car blows the hair and clothes of passers-by, but passers-by don't know that a car has passed by them, and they are wondering why a gust of wind suddenly blows, until they look around in a daze, and find that a car has already quietly gone away, and then they understand the culprit who messed up their hairstyle. It turned out to be the motorcycle that could only see a shadow.

In Zhang Lan's impression, among all the motorcycles he knows, only the "Tianjin-Honda 90" jointly produced by Tianjin Motorcycle Factory and Honda of Japan in the early nineties can be controlled at this level: the original "Tianjin-Honda 90" is a 90-cc four-stroke single-cylinder engine imported from Honda of Japan, with a silencer imported from Honda, limited to the limitation of exhaust volume, although the whole car is not very good in terms of power performance. But the silence effect of the engine is indeed absolutely first-class, and the sound of the engine can hardly be heard when running, and you can often see a rider riding a Honda 90 on the street when driving quickly through the crowd, because of the wind brought up by the car and blowing up his clothes The person with a confused expression on his face, and thought that a gust of wind suddenly blew, and he didn't know that he had just run a car next to him.

In Zhang Lan's view, this mute effect is almost similar to the electric cars that run all over the streets of China regardless of city or countryside, and when they suddenly drive past you, it can bring some terrifying effects. \//\

"Now what tests are they doing?" Looking at the engineers who were busy working, Zhang Lan asked curiously. Well, as for why Zhang Lan didn't ask those busy engineers, but asked Xie Fei directly, the reason is of course very simple, because those guys are busy recording all kinds of data, conducting various tests, and devoting themselves to their work, directly ignoring their bosses. At present, only Xie Fei and Xie Da Engineer are barely an idler.

"What they're doing is ......"

"Just when Engineer Xie Fei Xie was about to explain to Zhang Lan what they were busy with, it happened that an engineer who was about to carry out the next step of the test work passed by Zhang Lan, looked at Zhang Lan who was blocking his path, and said very politely, "Young man, look at you so young, newcomer, right?" Why is it so eyeless? Don't you see everyone busy here? Don't hurry up to work? What are you standing here in a daze? ”

Ahem, Zhang Lan touched his nose and was very embarrassed to make way for the conscientious and responsible engineer, as for the conscientious and responsible engineer, after seeing that Zhang Lan had already made way for himself, he pushed and walked away by himself: he was so busy that he had time to take care of a new little guy? ,

Xiao Chenxi and Alice were there at the same time and laughing: Anyway, they were scolded by their own employees for the boss, and the boss was embarrassed, as if there were not many. \//\

"This guy is good," Zhang Lan shrugged and found a good excuse to save a little face for herself, "If the employees of the company are so serious and responsible, I would rather be scolded every day." ”

Everyone chuckled, and after a small episode passed, Engineer Xie continued to explain to Zhang Lan, "What they are doing now is to prepare for the strength test of the engine. ”

Looking at the doubts in Zhang Lan's eyes, Engineer Xie had to continue to explain to him, "The ceramic engine is different from the traditional metal engine, although the ceramic engine is indeed excellent in various performance indicators, but it is too brittle, which is its only shortcoming. But this shortcoming is determined by the characteristics of the ceramic itself, the brittleness of the ceramic is unavoidable, what we have to do is to try our best to reduce this shortcoming. ”

Zhang Lan and Alice nodded, motioning for Xie Fei to continue.

"After our efforts in the past five years, we have finally found a more ideal composite ceramic formula, the material of ceramics made by this new ceramic formula is not inferior to the traditional metal engine material in terms of mechanical strength, but ceramics are still ceramics after all, and there is a certain ductility compared to metal materials, and ceramics are not good. Now we are testing this to see if the ceramic engine we designed with the new formula can make up for this lack of strength in the case of insufficient ductility, so that it can meet the requirements of practicality. At the same time, the extreme performance of this engine was tested. ”

This time, not only Zhang Lan, but even Zhang Zongjun and Yang Zhi, who were on the side, nodded, and finally understood what was going on. I finally knew why there were so many pipelines on that engine.

"How does this test work?" Knowing what was going on, Zhang Lan's curiosity came up again, "Strength test? You can't just take a sledgehammer and knock it hard to see which one is stronger, right? ”

Hearing Zhang Lan's words, Engineer Xie suddenly almost fell down with garlic under his feet, and his face was also blue and purple for a while, which was extremely exciting, obviously he was quite thundered by Zhang Lan's words.

Zhang Zongjun and Yang Zhi couldn't bear to turn their heads: Why did his son, such a smart person, suddenly become so confused?

Only Xiao Chenxi and Alice looked at Zhang Lan with sympathy, with a look of "we sympathize with you". It's just that in Zhang Lan's opinion, this look seems to have most of the schadenfreude in it.

"This," it took a long time for Engineer Xie to breathe down, and the expression on his face was no longer blue for a while and purple for a while, and said to Zhang Lan with difficulty, "In principle, this is almost the meaning." ”

In principle? Zhang Lan pursed the corners of her lips: In principle, bamboo dragonflies and helicopters are the same principle, but are these two things comparable? This guy is really tactful.

"We designed this engine, decided to start with our company's best, but also a relatively simple structure of the motorcycle engine, the design displacement is 250 ml, according to our calculations, theoretically the maximum speed of this engine can reach 20,000 rpm, the safe maximum speed can reach 17,000 rpm, which is the highest speed that the internal combustion engine can achieve, but whether it can meet the standard we designed, but after the next test to know." Engineer Xie said.
