The true injection technology of gasoline engines is very simple to say, it is nothing more than to let the cylinder exhaust exhaust gases and draw fresh air, the gasoline nozzle injects fuel into the cylinder, instead of the previous injection from the intake tract. In this way, the gasoline can be better atomized, and it can be fully mixed with the air, and when the work is done, the gasoline can be burned more fully, so that the engine can output more and higher power.

However, there is a problem here: when the gasoline is well mixed with the air, the concentration of the gasoline may be low and it will not be easily ignited. On the contrary, if too much gasoline is injected, the gasoline will not burn sufficiently due to the scarcity of oxygen in the cylinder, and the advantages of true injection technology will not be reflected, and it is likely that some gasoline will not be burned and gasoline will be wasted, such as traditional engine technology.

Not to mention the previous mechanical direct injection technology, which also injects gasoline into the cylinder after the ignition is turned off, causing the gasoline that cannot be burned to enter the engine oil and dilute the oil. The car has to change its oil every time it travels.

Meng Wentian now needs to solve the problem of ideas: first, abandon mechanical direct injection, adopt electronic chip control direct injection, not only after the engine is turned off, but also can change the injection time and amount of fuel according to the change of environmental parameters in the cylinder. Second, it is necessary to ensure that the gasoline in the cylinder is fully atomized to ensure that the gasoline can be burned smoothly, but it cannot cause gasoline waste.

The first problem is difficult, the difficulty is in the design and manufacture of chips, the idea is that the current Tianlan Automobile Research Institute does not have any ability to design and manufacture chips, and if you want to solve this problem, you can only buy ready-made chips. Even if Meng Wentian was a reborn person, he had no way to solve this problem for the time being.

However, only with chip control, direct injection technology can be upgraded to EFI technology, and Meng Wentian can't spare the chip problem.

For the second question, Meng Wentian's ability is much larger. Because he knows at least seven or eight ways to solve the second problem, and each of them is a new technology, a new technology, he can confidently and boldly apply for patents, and then transfer those patents, even to the original owners of those patents.

Of course, the original owners of these patents refer to the earth, in this Blue Alliance Star, and it is difficult to say whether these companies can develop these patents, after all, the earth and the Blue Alliance Star are still different, isn't it? If Meng Wentian does not plagiarize them, they may not be able to develop them as smoothly as on the earth.

Therefore, Meng Wentian does not have a little guilt for plagiarizing these technologies, just like he plagiarized songs on the earth, there are many good old songs on the earth, isn't there no one on this planet?

As soon as Meng Wentian arrived at the Automotive Research Institute, he convened a meeting with the experts to talk about their understanding of gasoline engine direct injection technology and their recent research progress.

The experts looked at each other one by one, even Yan Weizheng and Professor Zhao, who had entered the institute earlier, also looked surprised, and the others even looked like they had seen the hell: Is the private enterprise really so unsympathetic?

Looking at their expressions, Meng Wentian knew that his requirements were a bit difficult, and he also understood what they were thinking: after all, it was only a little more than a month since they were recruited into Tianlan Automobile Research Institute, not to mention what results were researched in this short period of time, even the collection of relevant information was enough.

However, Meng Wentian still had to do this, because he didn't want them to start from the most basic research, but he wanted to guide them on how to achieve corner overtaking. If we go according to the rules, what can such a small research institute do in the future wave of large-scale popularization of automobiles? It is estimated that it will not even be able to drink a sip of soup.

Although the experts slandered Meng Wentian, the boss, and scolded him in their hearts for being Zhou Papi, they still stubbornly asked: Who calls others the boss, and who makes them jealous of the high salary he offers? Besides, they don't ask you to necessarily research any technical achievements, but they just want us to talk about our experience. Let's talk about it, who is afraid of whom, anyway, the people here have passed this period of running-in, although they don't know the roots, but everyone knows that in the direct injection technology of gasoline engines, everyone's level is about the same, and no one has the qualifications to ridicule anyone.

In their eyes, Meng Wentian is just a rich boss, no, it should be said that he is the son of a rich boss, he is a high school student who definitely doesn't understand technology, what they say, it is estimated that they are confused, and they are not even qualified to admire.

So, under the leadership of Yan Weizheng, the experts began to speak one after another.

Although some experts did not talk about the gasoline engine direct injection technology itself at all in their speeches, they were all talking about how he collected information, if the data were summarized, or the level of direct injection technology in Germany and the direct injection technology level of the Japanese island countries, Meng Wentian was still quite satisfied, at least it showed that they had worked hard.

Moreover, Professor Zhao and Wang experts who he had high hopes for really did not disappoint him, one talked about chip control technology in his speech, mentioned the function that the chip should have if it is used in direct injection technology, and compared the control chips purchased by Huaxia Guoneng at present, and put forward the suggestion that the institute only purchase advanced control chips abroad, and even suggested that it should cooperate with famous foreign chip manufacturers to develop special direct injection control chips.

Of course, there are many problems with his ideas, and some of the problems can even be heard by Meng Wentian, but there are many reasonable elements in his suggestions, especially the requirements for the function of the chip, which makes Meng Wentian secretly happy in his heart, and feels that he has picked up a treasure: he already has this understanding and foundation, as long as I tell him the chip technology I knew in my previous life, he may be able to follow this line of thought and make surprising achievements to the world.

Science and technology are sometimes a layer of paper at all, as long as someone pierces it, he can take the lead. Now Meng Wentian can not only help him pierce that layer of paper, but also use the knowledge of his previous life to ensure that he sticks to the right direction, and it is difficult for him not to make any achievements.

Expert Wang studied gasoline injection technology, and his speech did not disappoint Meng Wentian.

I only heard him stand in front and say, "...... Through this period of research, I have encountered a contradictory question, that is, whether the atomization of gasoline should be thorough? This question, at first sound, a bit naïve, is it? Since it is direct injection technology, of course, the more thorough the atomization, the better, only when the gasoline and air are thoroughly combined, the gasoline can be burned more fully, and the energy contained in the gasoline itself can be fully released and transmitted to the engine. ”

Speaking of this, he changed his words and said: "However, the volume of the engine block is certain, and it can't hold too much gasoline if it is burned once." And once this gasoline is fully atomized, it is difficult to ignite it, because its concentration in the air is too low, and it cannot burn at all without high temperatures. ”

Seeing that everyone nodded, he said again: "And to make it burn, there are only two ways to do it." First, inject more gasoline to make it so dense that it burns easily, and it burns immediately as soon as there is a little fire. The problem is that the extra gasoline is simply redundant and not needed by the engine. Extra oil not only wastes but also significantly reduces thermal efficiency conversion. This method obviously doesn't work. The second method is to increase the temperature in the cylinder, especially the ignition temperature, so that the gasoline can burn in time. For example, increasing the ignition point, for example, trying to prevent the cylinder from burning and then cooling down quickly. But neither of these options will work. ”

Several technicians and experts nodded and agreed with Expert Wang's statement.

Because we all know, it is not easy to increase the ignition point in the cylinder, because the machining accuracy of the cylinder is very high, adding additional accessories on the cylinder block will greatly increase the processing difficulty, which will lead to the reduction of the strength of the cylinder, and the ignition equipment can not increase the temperature in the cylinder body, if the ignition point is increased because of the low concentration of gasoline, it is just to let the gasoline around the ignition point burn in time, and the gasoline in the distance can not be burned, in this way, it is not possible to add a large number of igniters densely around the cylinder block？

And the way to keep the temperature in the cylinder does not decrease. Anyone who has studied thermodynamics knows that only when the temperature difference changes greatly can the thermal efficiency conversion be high, and the energy contained in gasoline can be released more fully. If the high temperature of the cylinder block has been maintained, not to mention that the life of the cylinder block will be short, the requirements for the engine will artificially increase the difficulty of processing and production, and more importantly, the energy contained in gasoline cannot be released, and the advanced nature of direct injection technology to save fuel has become an empty word and a lie.

Seeing that the experts were all thinking hard under the guidance of Expert Wang, and seeing that Expert Wang was at a loss, Meng Wentian was happy in his heart, he knew that the time had come for him to pretend to be forced and plagiarize the earth's technology.

He stood up with a smile and said, "Experts, how about I tell me what I think?"

Everyone looked at this kid who had just finished the college entrance examination in surprise, many people disagreed, and a few upright people were even more disdainful: What do you know, have you heard of the principle of thermodynamics?

However, no one spoke out against it, because this is Meng Wentian's research institute, and he himself works for Meng Wentian, and this technical seminar was originally organized by Meng Wentian.

As the saying goes: just treat him as a fart.

Meng Wentian didn't care about other people's attitudes, he walked up with a smile and said: "On the one hand, we hope that the more fully the gasoline is mixed with the air, the better, that is, the more fully the gasoline is atomized, the more fully the gasoline and the air are in contact, and the more energy it releases from combustion." But here's the downside: it's less likely to burn. What to do?"
