All round car designer

Chapter 37 First Author?
Zhang Xiang on the side was completely stunned.

and many more!

What did Teacher Xu say just now?
This junior, who looks six or seven years younger than him, is the inventor of this injection system?
How can it be?

You must have heard it wrong!
Zhang Xiang couldn't accept this fact in his heart, the contrast between the two results was too great!
But no matter what Zhang Xiang thought, Zhou Fei, who was sitting there, had already started his own "performance".

"Actually, there are two plans for the EFI system that I initially imagined. One is what Mr. Xu sees now, and the other is not fully shown due to time reasons, but I have already completed the design of the second set of plans. .”

"Is there a second solution? Then tell me how this solution can further improve the external characteristic curve." Xu Nan asked excitedly.He was just asking casually, but he didn't expect that Zhou Fei really had an improvement plan?

"This system, I call it the single-point injection system, as the name suggests, the whole system has only one fuel injector, that is, the injector is placed at the position of the original carburetor, although compared with the carburetor, the single-point injection has been greatly improved The performance of the engine has been improved, but there are still many deficiencies.”

With that said, Zhou Fei took the assembly drawing of the single-point EFI from the table and continued,

"Mr. Xu, you can take a closer look. The single-point injection intake manifolds are different in length and installation position. The result is that the amount and time of mixed oil and gas in each cylinder are inconsistent, resulting in differences in their working conditions. , this may have no effect on a single-cylinder engine, but if it is placed on a four-cylinder engine, the external characteristic curve will definitely be weakened!"

"Since single-point injection has such shortcomings, how about installing more injectors?" Zhang Xiang blurted out subconsciously.

"What this senior said is the second set of plans I designed." Zhou Fei looked at Zhang Xiang with a smile, and then said, "I call the second set of plans multi-point injection."

"Then where are you going to put these injectors?" Xu Nan didn't react for a while.

"At the intake port of each cylinder!"

Xu Nan fell into thinking immediately, and Zhou Fei's answer gave him a lot of inspiration.

"That is to say, each injector will be controlled by the ECU to inject individual cylinders, and gasoline will be injected directly to the front of the intake air of each cylinder, and then enter the cylinder together with air to form a mixed gas. It’s a genius idea!”

Thinking about this point clearly, Xu Nan slapped his thigh suddenly, why didn't he think of this himself!

With multi-point injection, the engine can control the air-fuel ratio more accurately. It can inject fuel according to the timing, and accurately control the fuel injection quantity and fuel injection timing, so the power performance is better, the emission is better, and it is more economical. Save fuel!

Zhou Fei smiled and did not continue. Compared with EFI, Zhou Fei has a more perfect fuel injection method, that is direct injection in the cylinder!

However, at present, EFI is already a very advanced injection method. As for direct injection, Zhou Fei will not consider making it available in this world until the time is right.

Judging from the current situation, Zhang Xiang has basically confirmed that Zhou Fei is indeed the inventor of this system. Can't compare to a junior who didn't graduate?
Dry!
However, thinking that even Xu Nan did not independently develop this system, Zhang Xiang seemed to get a little comfort.

It's not that I'm too good, but that the other party is too awesome!

Well, that's it.

Immediately afterwards, Xu Nan had a detailed discussion with Zhou Fei on the issue of engine injection. However, what Zhou Fei has learned so far is only limited to EFI, and the rest needs to be improved.

"Papers and patents must be published as soon as possible, especially patents. It is best to finish writing all the materials within two days. If there is anything you don't understand, feel free to come to me."

Before leaving, Xu Nan did not forget to remind.

"In addition, when applying for a patent, don't apply in the name of the school, but in your own name." Xu Nan continued.

Although applying in the name of the school can reimburse the relevant application fees, it also means that the school has the final right to interpret the patent. Compared with the huge potential of this patent, this application fee is nothing!

"Understood, thank you Teacher Xu." Zhou Fei replied gratefully.

***
In the next two days, Zhou Fei and Jiang Yang temporarily focused their work on EFI patents and the writing of papers. At the same time, they handed over the completed parts drawings to Xu Nan, and he helped to contact the manufacturer. in production.

It was the first time for Zhou Fei and Jiang Yang to write papers and patents, and they were not familiar with many places. Fortunately, with the help of Xu Nan, they directly asked Zhang Xiang to guide them in the patent application.

The current Zhang Xiang is full of admiration for Zhou Fei. When he is busy changing the history of automobile development, what is he doing?

I am actually wondering if my hair is getting less again!

What is a genius?

Zhang Xiang only looks for Zhou Fei now!
With Zhang Xiang's guidance, Zhou Fei and Jiang Yang completed all the writing work in less than three days.

"Brother, I have already sent you the thesis and patent application, please take a look and see if there is anything that needs to be revised." Zhou Fei called Zhang Xiang immediately.

"Okay, I can finish the review by tonight at the latest, and then you can modify it according to my marks."

After hanging up the phone, Zhang Xiang opened the mailbox directly, found the attachment sent by Zhou Fei, and then looked at it seriously.

The juniors who are in the same laboratory as Zhang Xiang feel that their senior brother is a bit strange recently. He always receives calls from someone, and often works overtime in the laboratory until the early hours of the morning.

It stands to reason that Zhang Xiang will be graduating next year, so there shouldn't be much to do, right?

"Do you think the brothers are writing some papers?" One of the brothers asked curiously.

"Basically, maybe I want to publish another SCI before the competition?" The only junior sister in the entire laboratory replied.

"I'm curious what the brother is writing, why don't we go and see?"

The junior brother's proposal was quickly approved by other people. Just at this time, Zhang Xiang went to the bathroom, and several people came to his computer. On the interface, the paper written by Zhou Fei was still stuck.

"Research on an electronic fuel injection system... I'll go, the name is very high, it must be the project that Mr. Xu gave to the brother!"

"Wait a minute, turn up the paper, who is the first author of the paper?"

"It must be Teacher Xu, and then you can be a senior brother. Isn't this a common practice?"

However, when they saw clearly the signature under the title of the paper, everyone couldn't help but widen their eyes, because the first author of this paper was neither Xu Nan nor Zhang Xiang!

It was Zhou Fei!

Zhou Fei?

First author?
Who is Zhou Fei and Nima?
