"Another project?" Luo Yuzhong looked at Zhou Jingming with a surprised expression, "Then tell me what kind of project it is." ”

"It's still related to the engine injection system, aren't you studying the multi-point EFI system now, this time, I want to go one step further on the basis of multi-point EFI, so that the power and fuel economy of the engine can be improved to a higher level!" Zhou Jingming said with burning eyes.

"More advanced injection system than multi-point EFI?" Luo Yuzhong's face was even more puzzled, in his cognition, electronic injection is already the most cutting-edge technology of engine injection in the world, in addition, he really has not heard of any injection system, which is more advanced than electronic injection.

Not to mention multi-point EFI, in the era when carburetors are still kings, even single-point EFI is very rare, what will be the more advanced technology that Zhou Jingming said?

"lineDirectInjection, i.e. direct injection technology in the car engine!"

"Direct injection in the cylinder?" Luo Yuzhong was stunned for a moment, and then asked with some uncertainty, "According to the literal meaning you said, can I understand that the gasoline is directly injected into the cylinder?"

"That's right!" Zhou Jingming nodded, "It is to place the fuel injector in the cylinder, and directly inject the fuel into the cylinder to mix with the air to form a mixed gas, instead of injecting in the intake manifold like a traditional engine, and then forming a mixed gas into the cylinder." ”

"Direct injection in the cylinder...... It should use the principle of high-pressure injection to inject gasoline into the cylinder, if so, then the air-fuel ratio and compression ratio of the engine can be rapidly increased on the basis of the original, and the output torque of the engine will also be greatly improved!

"That's right, whether it's carburetor injection or electronic injection, it's all injected in the intake manifold, and to some extent there is still an uneven mixing of oil and gas, but if you use direct injection in the cylinder, you can control the mixing of oil and gas more accurately, how about it, Lao Luo, are you interested in doing this with me?"

Luo Yuzhong thought about it seriously, and then replied, "Xiao Zhou, the idea you just mentioned is very novel, but I think it is difficult to overcome the technical barriers by relying on our own words, why don't you go to Volkswagen or Bosch to cooperate, especially Bosch, it is definitely a big brother in the field of engine injection technology, and it will be better to cooperate with them?"

Luo Yuzhong was so frank, Zhou Jingming didn't want to hide anything, but replied, "I won't tell you, I am ready to apply for a patent for the technology of direct injection in the cylinder, and the cooperation must be cooperated, but not now, in the early stage, I still want to rely on our own ability, it is best to make a sample, and then I will consider cooperating with Bosch." ”

"If you think so, I will definitely support you, if we can develop this injection technology, then if we talk about cooperation with Bosch in the future, the waist rod will also be stiff!" Luo Yuzhong paused, and continued, "But you just proposed to let me join your research, I thought about it carefully, at present, my own burden is already very heavy, Santana's localization and VR6 project, I can't be busy, you said direct injection in the cylinder, I really lack skills." ”

"I haven't thought that through, you do have enough projects over there. Zhou Jingming nodded seriously, "Then I'll go find the rest of the people to take a look, but if there are any technical problems at that time, I will still ask you for advice." ”

"This is natural, but I can only give some suggestions within the theoretical scope of traditional engines, what you said about direct injection in the cylinder, there should be a lot of electronic technology involved, for this knowledge, I can't do anything. Luo Yuzhong replied with a smile.

"Okay, I'll figure it out by myself first, and I'll come back to you if I encounter any problems. ”

After finalizing this idea, Zhou Jingming was thinking about who to find to study with him on the way back. As early as 1950, Borgward launched a car equipped with a direct injection engine, but it did not attract the attention of the industry at that time.

What Zhou Jingming wants to do now is to strengthen the relevant design of direct injection in the cylinder on the basis of his predecessors, and gradually overcome the shortcomings of the previous direct injection in the cylinder, so that it can reach the level of mass production.

With Zhou Jingming's understanding of in-cylinder direct injection, even if he is working on this project alone, in fact, it is completely possible, after all, the most important working principle and internal components of in-cylinder direct injection, Zhou Jingming is very well understood, and Zhou Jingming can cooperate with Bosch in the follow-up engine test, but the core technology is still in his own hands.

However, simply relying on himself, rather than relying on the strength of the team, then this technology is ultimately only understood by him, and it cannot play a role in improving the industrial level, so Zhou Jingming's idea is to find at least a reliable partner, two people to jointly develop direct injection in the cylinder, and then apply for this patent in the name of the future innovation studio!

As for the candidate, Zhou Jingming already has a definite goal in mind, that is, his college roommate, Wang Yuanchao, who is now working at the Nanqi Research Institute.

When attending the graduation ceremony last year, Wang Yuanchao's father Wang Shuo once mentioned that Wang Yuanchao should study behind Zhou Jingming, but the scale of Xunming Gear Factory was still very small at that time, and Zhou Jingming did not agree. Now he also has his own innovation studio, and the technology of direct injection in the cylinder is definitely the cutting-edge technology in the engine.

After making up his mind about this, early the next morning, Zhou Jingming came to Jinling City by car, this is the first time he has come here, but Zhou Jingming is not very strange to Nanqi, after all, in his previous life, his first job was in Nanqi, and after working here for three years, he was transferred to Nanqi Research Institute, so this time back here, Zhou Jingming can even feel a sense of intimacy.

After coming to the Nanqi Research Institute, Zhou Jingming soon met Wang Shuo, the president of the Nanqi Research Institute.

For Zhou Jingming's visit, Wang Shuo was very surprised, Zhou Jingming's acquisition of Shencheng Automobile Gear Factory, Wang Shuo had already heard about it, and his appreciation for Zhou Jingming in his heart was becoming more and more intense.

After clarifying the purpose of his visit, Wang Shuo did not hesitate, and immediately agreed to let Wang Yuanchao follow Zhou Jingming to engage in direct injection in the cylinder, and worked in the Nanqi Research Institute for so long, Wang Shuo is very clear about the working environment here, although the title is "Research Institute", but in fact there is no innovative work here, if Wang Yuanchao stays here, it is impossible to achieve much.

In this way, the team of direct injection in the cylinder will be determined, and then it is time to enter the actual research stage.
