reborn industrial empire

Liu Mei helped Jin Xiaoqiang and the others go to the school gate and ordered some takeaway food. When she came back, she happened to see Jin Xiaoqiang explaining another technology to Liu Xiaoliang.

Liu Mei also admired the two people's focused expressions. She originally came from this school of science and engineering, so she was quite familiar with some of the school's customs.

Although Nanyang University of Science and Technology is not the kind of famous university that can be well-known in the 211 Project, it is still quite famous in science and engineering, especially in automobile engine design.

In Jin Xiaoqiang's previous life, he had trouble finding a job in this city after graduating from college. Then a car company in the south happened to be looking for someone, so he went there to make a living.

Unexpectedly, he has been there for five years. Unfortunately, private companies also have their drawbacks. In addition, in his previous life, he was a person with relatively average qualifications, so he did not become famous.

But after being reborn, it was different. After all, the concepts and designs in his mind were all things he had personally seen in his previous life and had been refined over time on various types of cars.

And these things can be said to be quite advanced for the Chinese engine design industry, which is just in its infancy.

In his previous life, when he went to repair cars, Jin Xiaoqiang had become a complete technical maniac. Now he was explaining the technology to Liu Xiaoliang, which was particularly interesting.

Liu Xiaoliang has been pestering Jin Xiaoqiang to tell him about the cvvt technology that is commonly used in car engines. To put it bluntly, this technology is the breathing technology of the engine.

This VVT technology, whose Chinese name is Variable Valve Timing Technology, was a technology developed by Fiat in the 1960s and 1970s, but in the end it was widely used in the hands of the Japanese.

Honda, in particular, has mastered the application of this technology. In the last century, when Honda entered the international market and Toyota fought hard to seize the market, this technology added a lot of points to the Honda brand.

With the development of the automobile industry, the reduction of oil resources, and human needs for environmental protection, the development concept of engines in this century will never return to the one in the 1970s that never needed to consider oil prices and displacement.

The golden period of engine development.

The development concept of engines in this century is that the weight is getting lighter and lighter, the displacement is getting smaller and smaller, and the power requirements are getting larger and larger...

This requires major automobile manufacturers to rack their brains to develop and use more advanced technologies in engines.

Among them, the most perfect application of this technology is Honda's vtec engine. This technology has been applied to many Honda models since the late 1980s, from Accord to Civic, and it is used once it is used.

Twenty years.

However, Honda cars equipped with this technology have been sold around the world for more than 20 years, but they have been reluctant to introduce this technology to China. This has also made many consumers complain about consumer discrimination, but they have no choice but to do so.

What a hateful thing!

This vvt technology will also be popularized in China in the next few years, but Jin Xiaoqiang remembers clearly that when this technology really becomes popular, it will be in the late 2010s.

, before this, everyone was still stuck by foreign manufacturers.

It wasn't until the two car companies, Ricky and Lige, made technological breakthroughs that other car manufacturers began to see hope.

However, Jin Xiaoqiang, who knows the internal situation of the industry, is also quite uneasy about the so-called completely independent VVT technology, because the core part of this technology is a series of data in the ECU, and as far as he knows, those domestic cars

Manufacturers, their so-called vvt technology, generally buys data from abroad...

But now that Jin Xiaoqiang is explaining the VVT ​​technology of the engine to Liu Xiaoliang, he has a very secret idea in his mind. Only he knows this idea, but it is not the time for a showdown with Liu Xiaoliang yet...

"This VVT technology, to put it bluntly, is that when the engine is running, through the electronic control unit, based on the data displayed in various parts of the engine, it continuously adjusts the opening and closing time of the intake valve on the cylinder as the engine runs.

There is also an angle, so that the maximum amount of air can enter the inside of the cylinder, reach an optimal mixing ratio with gasoline, burn, and release energy. This can improve combustion efficiency, achieve the purpose of saving fuel, and get corresponding more

Great power..."

At this time, Jin Xiaoqiang began to popularize the knowledge of vvt to Liu Xiaoliang. In fact, when they were in school, the teacher also explained these things in class.

Unfortunately, after all, no one has ever seen a real VVT engine, so everyone's impression of this technology has remained at the stage of books. Everyone is not very clear about how this technology is implemented.

Jin Xiaoqiang explained to Liu Xiaoliang how to add several ingenious devices to the engine and adjust the opening and closing angle and time of the valve back and forth according to the rotation of the engine.

Liu Xiaoliang was originally a technical geek, and he did have his own uniqueness in mechanical aspects. Now that he heard Jin Xiaoqiang's explanation, he immediately understood the cvvt technology that Jin Xiaoqiang was talking about.

After seeing Liu Xiaoliang's glowing expression of understanding, Jin Xiaoqiang simply didn't hide it, so he said to Liu Xiaoliang.

"Okay, now that you have understood the technology of cvvt, now I will tell you about the technology of dvvt, and this technology will become the mainstream of engine technology development in the next few years."

"Oh? What other dvvt technology?"

The Internet today is not as developed as it was in later generations, and consultation is relatively asymmetrical. This dvvt technology was actually born a few years ago, but there are many people in China who have never heard of this technology.

.

"Of course, if there is SOHC, there will be DOHC. Now that there is CVVT, of course there will be DVVT."

"Haha, okay, Xiaoqiang, don't show off, talk quickly..."

Liu Xiaoliang was going a little crazy now. He felt that what he had learned from Jin Xiaoqiang in the past two days was really not much weaker than what he had learned in four years of college.

In the four years of college, he only learned some basics, but the knowledge that Jin Xiaoqiang brought to him in the past two days made him feel that he had completely made a breakthrough in his knowledge and understanding of engines, reaching a level of

New realm.

For example, it turned out that he thought that this is what engines do, and everyone does it.

But when Jin Xiaoqiang said this, he realized that the engine could be built like this? And the benefits of building it this way turned out to be so many?

This is equivalent to opening up a world for Jin Xiaoqiang that is completely different from what he knew before!

"Hey! I said you two don't want to eat? The rice is already cold!" |

Seeing that Jin Xiaoqiang and Liu Xiaoliang had no intention of stopping, Liu Mei couldn't help but snorted beside her, and then said.

She had just returned from buying a lot of takeaways for the two of them, but when she came back, she saw that the two of them were arguing fiercely and chatting about technology in full swing.

Liu Mei didn't want to interrupt the two focused men, so she didn't say anything. But now that she saw that the two men had finished their conversation and still had no intention of stopping, she had no choice but to say something.

"Ouch! It's already past six o'clock, right? Are you really hungry? Xiaoliang needs to eat something first, and we'll wait until the rest is finished..."

When Jin Xiaoqiang heard Liu Mei's reminder, he came back to his senses from the state just now. It was already past six o'clock. He had been here since he came from the iron factory at past eleven o'clock in the morning.

I was talking about these technologies with Liu Xiaoliang, but I didn't expect that I kept talking all afternoon. It's already past six o'clock now.

Liu Xiaoliang was also hungry at this time, so he immediately stopped being polite, took two lunch boxes from Liu Mei's hand and started eating.

Jin Xiaoqiang looked at the way Liu Xiaoliang was distracted even while eating, and knew that this boy must still be immersed in the world of technology he just described to him, so he simply didn't remind him, so he turned around

He turned around and looked at Liu Mei with a smile and asked.

"You haven't eaten either, right? Come on, let's come together."

"Hmph! If you, the boss, don't open your mouth, how dare I eat first!"

Liu Mei pretended to be angry and complained to Jin Xiaoqiang. Apparently she was a little dissatisfied that Jin Xiaoqiang was completely immersed in academic discussions just now and neglected to eat.

Jin Xiaoqiang didn't say much to her, took two lunch boxes and started eating...

After finishing the meal quickly, Jin Xiaoqiang was pulled over by Liu Xiaoliang and started to explain the dvvt technology.

After the dvvt technology is introduced, it is actually very simple. To put it bluntly, it is based on the cvvt technology and adds a technology to adjust the opening and closing time and opening and closing angle of the exhaust valve.

On the engine, there is no need to make too many changes to the original things, but on the ECU, a lot of data needs to be recorded and a series of adjustments need to be made.

For Jin Xiaoqiang, who was more than ten years ahead of his time, these technologies were not worth showing off at all, but for Liu Xiaoliang, these technologies were simply revolutionary breakthroughs.

You must know that the current domestic engine development team, let alone cvvt and dvvt, even a dohc has not yet understood it very well.

Now if he masters these two different technologies, then as long as he is given sufficient time and resources, he can definitely come up with a 4g63 engine dedicated to the red-top evo that is not weaker than the original.

At this time, Jin Xiaoqiang was simply sitting aside, quietly observing the flickering light of ambition in Liu Xiaoliang's eyes...

A great feeling of 'cultivating' quietly emerged from Jin Xiaoqiang's heart. A great engine man in the future is likely to be 'initially trained' by himself...
