*******************
When Lao Liang spoke, his tone was a little heavy, but he was also a little relieved, in his opinion, only young people who can endure such hardships are the materials that can be created in the future.
And Li Yifan also seemed to understand what Lao Liang meant, and the people in the hall on the first floor were sleeping soundly, so Li Yifan asked Lao Liang in a whisper.
"I think these young people seem to be a bit of a noodle student, they don't seem to be contracted employees of the laboratory."
"Well, that's right, it's not, these young people are all automotive students I recruited from the provincial capital Institute of Technology and Harbin Institute of Technology, and they are all in the internship period now. Recruiting them to do things is cheap, and it can greatly liberate our scientific researchers, and most importantly, it can also pick out some of the materials that can be made from their gang and sign them under our laboratory in the future. ”
Li Yifan couldn't help but glance at Lao Liang with strange eyes, this Lao Liang looked very honest, but it turned out to be a calculating guy!
"Mr. Li, didn't you ask us to study the variable valve lift technology before? In fact, this technology, as you know, is the accumulation of data, and then controlled by the ECU, which requires long-term, uninterrupted experiments to record the opening and closing angles of the intake and exhaust valves, as well as the time, frequency, etc., of the engine under various working conditions, which requires the most boring data recording work. But you from ...... some time ago Where, there are so many good technologies, and now most of our R&D personnel. are digesting and absorbing those techniques. So such data recording. Analysis, and entry work, we need other manpower to complete, we have a shortage of manpower, the laboratory has limited funds, so I came up with such a solution. ”
Hearing Lao Liang say this, Li Yifan didn't think that this Lao Liang was cunning, it was indeed for the laboratory and these interns. It's a good opportunity to kill two birds with one stone, and it's really a good idea for both parties to get benefits.
"What is the progress of R&D?"
Li Yifan asked Lao Liang again.
When it came to the progress of research and development, Lao Liang immediately had a neck: "Haha, you can look at this, Mr. Li, we are now in three shifts, and people are not stopping, and we are rotating for 20 days a day." The engineers in Japan, Europe and the United States relied on the data accumulated over decades. But they didn't have computers at the time, and they worked eight hours a day. We have the technical data you got to back it up. There is so much manpower and powerless support, I dare not say anything else, in the middle of the year, we will be able to get the initial data accumulation, then we can load the car and test, and a variety of transmissions to cooperate with the experiment, if the time can still maintain such a large force of resources tilt and technical support, it is estimated that at the end of the year, we will be able to give you the finished product. ”
Lao Liang said it very easily, but Li Yifan knew that this was definitely not such an easy thing.
AFTER ALL, YOU MUST KNOW THAT TECHNOLOGIES SUCH AS HONDA'S VETC, TOYOTA'S VALUETRONIC, MERCEDES' VVT, BMW'S DAUBLEVANOS, ETC., ALL MEAN THE SAME THING.
In fact, to put it bluntly, it is a technology that controls the opening and closing time of the intake and exhaust valves, and the angle of opening and closing in the process of engine work.
But this technology, said very simple, but the actual control is quite difficult, it requires you to comprehensively monitor the engine speed, load, water temperature, etc., from the data, take out the best time, to control the opening and closing angle of the engine's intake valve, exhaust valve, and opening and closing time, so that the engine can achieve the best efficiency and send out the best power value under high and low revolutions.
This technology seems simple, but in fact, the requirements for data accumulation are actually quite unrealistic.
You need to accumulate the data of dawn to be able to extract the most suitable values from it, and then write it into the software control program, so that the ECU can control the engine while it is working.
These data have been accumulated by hundreds of engineers from large car companies in Europe, the United States and Japan over a period of decades.
And now we are struggling to catch up, and we have modern computers to help, but it will take a long time to complete this kind of data accumulation.
Lao Liang uses the most advanced technology, coupled with the oldest means, a combination of crowd tactics, to obtain these data.
The effect of this is quite obvious, that is, these data can be obtained in the shortest possible time, and his approach has also opened Li Yifan's eyes.
It turns out that the power of crowd tactics is so great in a high-tech environment like modern times, especially in such a basic data collection work, which can indeed reflect the power of such crowd tactics.
"But, just let these people sleep here, what if you catch a cold?"
"Hehe, how could it be, the environment here is much better than their school dormitory. There is geothermal heat here, and at this temperature, sleeping here is much stronger than their dormitory, and don't look at the floor, but our laboratory, even the floor is cleaner than their dormitory, do you believe it? ”
Lao Liang smiled and explained to Li Yifan that Li Yifan absolutely believed this.
How sloppy the dormitory of these tech nerds engaged in scientific research can be, Li Yifan can know with his ass.
"By the way, don't talk about this, you said that our experimenters are digesting and absorbing those techniques, how are you learning now?"
Li Yifan is quite concerned about this issue, after all, this involves a major event in the future direction of the company.
He doesn't want to be like other independent car companies, with such low requirements for himself, and he doesn't want to be motivated to eat in the low-end market.
As soon as he came up, he had to fight in the mid-level car market, which was quite cruel.
It's not enough for you to just assemble the car in place, the performance indicators of your car must also have a fight with others, and now Chenhua Automobile is the worst at this point.
In terms of engine and transmission, they are a little worse than other people's cars, and they can only catch the entry-level side of other people's intermediate cars, and the middle and high-end performance can pull them off, so for engine technology, he is now quite important.
"Well, everyone is very energetic now, after all, Mr. Li, what you got this time is all good things, especially for our group of scientific researchers engaged in research and development, everyone is very energetic. Mr. Li, I don't dare to promise you anything else, but you give me three years, no...... Two years, two years later, if we can't get the most out of these technologies and come up with a new engine for you, you can always let me roll up and fuck off......"
Lao Liang was a little ruthless here, and he wanted to make a military order with Li Yifan, Li Yifan smiled.
"How can it, Lao Liang, I also know that this engine can't be done in a day or two, don't be too anxious, don't have too much mental pressure......"
"Hey! Mr. Li, let me tell you this. In fact, this engine, especially the current mainstream four-cylinder engine, in fact, everyone's design, it is the same thing, there is not much difference. The bore of the engine, as well as the depth or something, are not bad, but there is a difference in the cylinder block and the material used in the cylinder head. For example, Volkswagen is trying to make a possible lightweight engine, so they plan to make an aluminum alloy engine, but aluminum alloy has a low melting point, so it may be no different from a cast iron cylinder in terms of robustness, but it may be a little worse in terms of durability. And the cylinder block wants to use aluminum alloy, which is still a little worse in terms of seismic explosion, so they want to find a way to use aluminum alloy to cast the cylinder block, but add a pure steel cylinder liner on the inside of the steel wall, but do this, because the cylinder head is made of pure aluminum alloy, so that because of the difference in friction coefficients, the final coefficient of thermal expansion is different, and finally it is not tight, and then burn the engine oil. The rest is no different, it is nothing more than the so-called tuning, in fact, it is to control the fuel injection time of the fuel injector and the size of the fuel injection through the ECU driving computer. We didn't do well before, in fact, because of the lack of data accumulation, after all, they have been doing it for decades, and we have only been doing it for a few years? And over the years, everyone has been impetuous, and not many people can really bother to do such data accumulation. But now you have created such good conditions for us, we want funds for funds, technology for technology, and so many experimental equipment, so ah, you can rest assured, I said that in two years, we will be able to build a new machine, you just wait and see! ”
Lao Liang said these words very confidently, he was to the point, in fact, before us, the difference was nothing more than materials, processing, and data accumulation.
Now Li Yifan can handle materials and finishing, and what they engineers have to do is nothing more than data accumulation.
Plug-ins such as variable valve bearings are added to the engine for data accumulation, and turbochargers are added to the engine for data accumulation.
Even when the time comes, the two plug-ins will be integrated into the engine, and then the data will be tested, Lao Liang is now quite confident, with the resources he has now.
In two years, he was really able to make a decent engine.
"Well, well, then I'm just going to say a couple of words, let's focus on the 2.0 liters, 1.8 liters, and 1.6 liters, or 1.5 liters, or even small displacement models like 1.4 liters. As for what V6, what V8 like the model, for us, it's useless. That kind of engine is not the future development trend ......" (to be continued......
