Chapter 8 VVT Technology

Just for this point, I also had to save this Yu Fei's life!

Looking at Yu Fei who was walking in front, Jin Xiaoqiang secretly pondered in the back.

In fact, today is also a coincidence, I happened to meet this Chai Liang, in fact, in the last life, the grievances between this Chai Liang and this Yu Fei are very big!

And it happened to be the grievances between these two people, and finally because of the earthquake in the officialdom of Nanyang City, it was the earthquake that directly led to the resignation of the current secretary of the municipal party committee and member of the Standing Committee of the provincial party committee, Xie Shengli.

However, Jin Xiaoqiang at that time was just a flat-headed ordinary man, and as for the reason for the fight, he heard others say it later, and what he said was also with a nose and eyes.

Later, he also had a few friends who were fighting in Nanyang officialdom, and later many years later, when everyone drank together, he also used to use what happened at that time as a talking point, but the Xie family's power, which was once a smash hit in the city at that time, has disappeared.

As for the deeds of the Chai Liang family, it was a year or two later that they were put into the "XX Statement" of the imperial court station, and Jin Xiaoqiang had specially watched that episode of the show at that time.

But those will be things that will only happen in the next few months, but now that Jin Xiaoqiang has been reborn, as a reborn person, and now there is such a good opportunity, he feels that of course he needs to make a very good investment.

And this investment will definitely change the fate of countless people......

The three of them swaggered to the Hu spicy soup breakfast restaurant, each ordered a bowl of Hu spicy soup, ordered a few meatloaf, and began to eat happily.

It's the cold season of spring outside, and eating a bowl of steaming spicy soup with a few meatloaf is really a perfect match for breakfast.

Before breakfast was served, Yu Fei ran to the outside of the shop to make a call, Jin Xiaoqiang saw it in his eyes, but did not squeak......

Yu Fei didn't often come to such a small shop to consume, he felt that it was not very hygienic here, of course, it was also related to his background, but today I don't know what happened, I actually came here with Jin Xiaoqiang and Liu Xiaoliang to have breakfast.

When I was in school, I lived in the same dormitory with these two for three years, but the relationship between us at that time was only average at best.

But I don't know why, yesterday's unexpected meeting, a drink of wine, and that fight, unconsciously, everyone's relationship seems to have become a little closer.

A friend who looked a little rusty suddenly seemed to have become a close friend.

"By the way, Xiaoqiang, shouldn't you graduate in a few years? Have you all found a job? ”

Yu Fei asked casually while eating the meatloaf.

"Well, I haven't looked for it yet? Xiaoliang already has a home. ”

Jin Xiaoqiang replied with a meatloaf in his mouth.

"Oh? What kind of job is Xiaoliang looking for? So what are you going to do? ”

Yu Fei asked again.

"You don't know our major, Xiaoliang went to the R&D department of Huazhong Automobile, me? I haven't planned yet, I might go home and work with my old man, to be honest, if I have the chance, I really want to develop a car of our own pure heaven dynasty! ”

Yu Fei casually mentioned it, but Jin Xiaoqiang thought a lot in his mind, to be honest, he had been reborn for a few days, and he really hadn't thought about what he was going to do in his life.

But it was Yu Fei's casual question, and Jin Xiaoqiang's casual answer, but he just told his dream from the beginning of his previous life to his rebirth.

He wants to build a car, to build a car that is pure to the Celestial Empire, a car that is purely man-made in China!

At the beginning of his last life, he traveled to several automobile manufacturing companies, and later could only be reduced to repairing luxury cars for the rich and their second wives, Jin Xiaoqiang once thought that he had forgotten his dream, but he didn't expect that this inadvertent question and answer suddenly said the most real and simple ideal in his heart.

"Yo! Want to build a car? Hehe, it seems that your dream is not small, isn't it? ”

Yu Fei replied half-jokingly, thinking that this might be just the impulsive words of Jin Xiaoqiang, a stunned young man who has never entered society and is still full of idealistic fantasies about society.

"Humph! It's up to you? Still building cars? Are cars so easy to build? ”

As Jin Xiaoqiang's hair and best friend for more than ten years, Liu Xiaoliang didn't save face for Jin Xiaoqiang at all, and directly attacked him.

"Rub! What's so hard about building a car? ”

Jin Xiaoqiang was a little annoyed by the attitude of the two people, and he was a little enthusiastic.

"Hey, hey! Okay, since you are so confident, you will develop an engine for me that will definitely be popular in the future? Can you grasp the engine trends of the future? ”

Liu Xiaoliang has now entered the design and development department of Huazhong Automobile, and now that department is working on a new car, and the project has been determined, but there is still no clue about it.

"Hey! What's so hard about that? It depends on the future trend of our country's automobile, according to my recent summary and analysis, the next few years will be a golden decade for the development of our Tianchao automobile industry. In the past few years, more and more people will enter the automotive industry, and the number of domestic independent brand car manufacturers will gradually increase. With the increase in the number of private cars in the future, in the future, small displacement, large power, high safety, fuel-saving and environmentally friendly models will be more and more popular with the people. ”

After so many years of car design in his previous life, and so many years of car repair inside and out, if Jin Xiaoqiang still can't understand the future direction of the automotive industry, then he is really living in vain.

"Yo drink! It's a bit of a doorway! It seems that during this time, you kid has really put in some effort! ”

Liu Xiaoliang was also stunned by what Jin Xiaoqiang said.

At present, the domestic automobile industry, high-end models, are basically monopolized by foreign capital or joint ventures, during this period of time the most running private cars on the market are Santana, Jetta, Xiali, Tianjin Dafa.

The mid-to-high-end political axe procurement cars, Audi, Toyota, or luxury cars driven by wealthy people, are basically fully imported.

Now in this year, Santana can still buy 180,000 yuan, Audi is about 400,000 yuan, the price of other cars has not been reduced, and the Accord produced by Guangqi Honda has not been under 200,000 yuan, not to mention Toyota Camry and the like.

"The future development trend of engines is more inclined to small displacement and large power. This technology is troublesome and troublesome, and it is simple, but it is actually simple. For example, the VVT technology that has been popular abroad since the eighties of the last century, if this technology can be developed, then the engine we launched will be absolutely popular. ”

Jin Xiaoqiang is still watching and talking.

"Hey! It's easy for you to say, but if you really want to understand the VVT technology, how can it be so easy? ”

When Liu Xiaoliang went to college, he was a technical maniac, and he was the most sensitive to this kind of technology, and this VVT technology is to adjust the intake and exhaust time of the engine cylinder, so that more air can enter the cylinder, so that the same gasoline can be burned more fully and provide more sufficient power.

This technology has matured as early as the eighties of the last century, among which the Honda car is the most slippery, and it is precisely by virtue of their unique VTEC technology that the Honda car quickly occupied the international market, and established a reputation and Toyota, Ford, General Motors, Mercedes-Benz BMW and other internationally renowned car brands.

"Hey! Don't believe it, what's so hard about this? You see, if this is an engine cylinder, and then we install several hydraulic control valves on this camshaft, so that when the engine reaches a certain set speed, the computer will instruct the solenoid valve to start the hydraulic system, push the small piston in the rocker arm, so that the three rocker arms are locked into one, and they are driven by a high-angle cam together, at this time, the lift and opening time of the valve are correspondingly increased, so that the air intake per unit time is larger, and the engine power is stronger. This sudden burst of power after a certain rev will greatly enhance the driver's driving pleasure. However, when the engine speed drops to a certain speed, the hydraulic pressure in the rocker arm is also reduced, the piston retreats to its original position under the action of the return spring, and the three rocker arms are separated. Isn't that what it is? ”

While explaining to Liu Xiaoliang, Jin Xiaoqiang simply drew a schematic diagram on the table, dipped in water.

Liu Xiaoliang is a well-known technical maniac in the school, and Nanyang City is also an old industrial base of the Celestial Empire, and the level of professors in the school in the automotive major is still quite good.

Although their awareness and knowledge level is still relatively backward, but some international advanced concepts are still understood, because of technical discrimination, up to now, this set of VVT technology has not been introduced into China.

At this time, the price of importing such a model is very high, and if you take it back for dismantling and research, the school will definitely not agree, so in that era, there are really not many people in China who understand VVT technology.

Liu Xiaoliang is a technical maniac, when he saw this simple schematic diagram drawn by Jin Xiaoqiang, he immediately understood what Jin Xiaoqiang meant, and was fascinated by the picture drawn by Jin Xiaoqiang casually.

"Yo drink! I didn't expect it, I didn't expect it, so it's okay? ”

Liu Xiaoliang's foundation in engine design is quite solid, although he has not actually participated in any design and finalization work, but he still knows the process of which work, and in the school, they can't afford to dismantle the advanced engine, but the old car engine, they don't know how many have been dismantled.

So he still has a good understanding of the design and structure of the engine, at this time Jin Xiaoqiang drew a schematic diagram so simply, he took a look at it, and immediately found out the general meaning of the schematic diagram drawn by Jin Xiaoqiang.

At this time, he couldn't help but look at this drawing, where was he in a daze, and sighed, when did this Jin Xiaoqiang suddenly become so powerful?

How could I never have imagined such a design before?

You must know that VVT technology can make the air more fully enter the combustion chamber, so that every drop of gasoline can be burned more fully, and then the engine can get more abundant power, so as to achieve the purpose of fuel saving and emission reduction.

"What's going on? That's it? ”

Jin Xiaoqiang saw where Liu Xiaoliang was contemplative, and couldn't help but say to Liu Xiaoliang a little proudly.

In fact, thanks to his car design in his previous life, as well as his experience in repairing cars, you must know that at that time, I didn't know how many luxury car engines were dismantled and unloaded by him.

It can be said that in the years before his rebirth, there were almost no famous cars and luxury cars that exceeded one million, and family cars that were less than 100,000 yuan.

In addition, he usually likes to delve into these things, once he disassembles an engine, he must have a glimpse of it, and coupled with his dedication to building a car, he really disassembles it himself, and records a lot of data on the internal components of the engine.

At this time, Liu Xiaoliang's question, coming to test him, really didn't bother him much.

"Hey! Xiaoqiang, do you think this VVT technology is so simple? ”

After figuring out the principles that Jin Xiaoqiang had just said, Liu Xiaoliang raised his head and asked Jin Xiaoqiang with a confused face.

If this technology is so simple, then how could the technicians of our Celestial Empire not think of it?

"Hey! If only it were that simple, this is just the principle, and the most critical core technology of this technology is on the ECU! The ECU should reserve the best valve timing parameter value, as well as the crankshaft position sensor, throttle position sensor, water temperature sensor, intake manifold air pressure sensor, etc. ”|

Liu Xiaoliang's question was to the point, Jin Xiaoqiang could only smile bitterly when he heard it, and then explained to Liu Xiaoliang.

This ECU is the so-called driving computer, which is the core key part of the current engine research, with such a pure electronic control unit, it can make the engine of the car, use the least amount of fuel, and send out the maximum horsepower.

And this ECU is also the dead end of the current Celestial Empire engine research......

To put it bluntly, it's not that it can't be created, but that everyone doesn't have the heart to devote themselves to research and establish a database.

You must know that the parameters like Jin Xiaoqiang just said are to go through thousands of experiments, record data, and then select the best parameters to input into the computer, and then record the values of other control units, and then match the best configuration through the computer.

It's like arranging a number series, tens of thousands of sets of data, it is possible to send out infinite possibilities, and then select the best combination from the middle, put it together, and control the work of the engine through the ECU when the engine is working.

The establishment of such a database, to the formation, and then to the formation of products, often may require a team, into the project for several years, or even thousands of experiments, in order to get the best match, and the investment in these experiments is also huge, and may even have to invest hundreds of millions of dollars to complete the experiment, who wants to do such an investment?

According to the current and future changes in the social form of the Celestial Empire, everyone is concentrating on keeping up with the RMB, and who wants to dive into dealing with these boring data?

And how many automakers are willing to spend such a big price to conduct such data experiments?

When Liu Xiaoliang heard Jin Xiaoqiang say this, he couldn't help but sigh, yes! The principle is very simple, but if you want to implement it, it is even more difficult.

Jin Xiaoqiang looked at Liu Xiaoliang's dejected appearance, and couldn't help but be happy, in fact, in his previous life, he had a record of the various technical peaks of VVT's ECU matching, what Toyota's VVT-i, what Honda's VTEC, BMW's ValueTRNIC, and Audi's AVS, all of which are talking about this technology.

But the data peaks of those technologies, he has them all in his mind, you must know that his biggest collection in his last life is the data magazines of those famous cars, and he recalls a lot of the data in them.

So if he really made these things come out, now theoretically, it really wouldn't be that difficult.

Yu Fei didn't understand what Jin Xiaoqiang and Liu Xiaoliang were talking about just now, he was not an automotive design major, but he also saw that Liu Xiaoliang didn't seem to be in a high mood now, so he hurriedly said to Liu Xiaoliang.

"Hey! Why do you think so much? Isn't Xiaoqiang quite thoughtful now? When the time comes, you guys will work together to get it, and I don't believe that we Celestial Empire people won't be able to make such a broken thing, okay, don't think about it now, eat first. ”

As soon as Yu Fei's voice fell, before Liu Xiaoliang could raise his head, the door of the small restaurant was suddenly pushed open, and then Chai Liang's duck neck voice came over.

"Good! You guys are really fucking kind, you haven't left yet, don't say anything, brothers, give it to me! ”
