Chapter 58 Completing the Test
As expected, as Wang Tianfeng said, when Zhou Fei woke up the next day, he even wanted to die. Although the soreness in his body was no longer so obvious, the soreness in his neck had just begun.

It's really like a stiff neck!
As long as the neck moves a little, it will be fatally sore. Zhou Fei can only keep his head as still as possible like a wooden man.

But even in this situation, Zhou Fei still did not give up training.As always, according to Wang Tianfeng's arrangement, one item after another was carried out.

At this time, the new semester had already begun. While many freshmen were pouring into the campus, Zhou Fei was also successfully promoted to a senior. There was only one year left before graduation.

It was rare for Wang Tianfeng to give Zhou Fei half a day off. Zhou Fei quickly took advantage of the last time to drag Jiang Yang around the freshman reception on campus.

Every year at the beginning of school, the busiest and most excited people, besides the students and parents, are also those "seniors" who are eyeing them, lazy people who don't even want to go to class, but at this time they have turned into those beautiful and lazy people. Shan's school girls carry luggage, add a contact information by the way, treat them to a meal by the way, and by the way...

For these girls who have just entered college, their minds are the most innocent, and they are also the easiest to deceive, so the saying "guard against theft, wolf and seniors" still makes sense.

Of course, Zhou Fei must not be included here, after all, he himself is very simple, except for Technician No. 66, no one should let him be distracted!
A good man is me, and I am Zhou Fei!

The welcome office of the Automobile Institute was placed at the entrance of the Shaw Building, and there were also the welcome offices of the School of Mechanical Engineering and the School of Communication next to it. Zhou Fei and Jiang Yang watched from a distance, as if they saw something from these freshmen. Myself three years ago.

"I didn't think there was anything special about welcoming new students before, but now I suddenly feel that time flies, and we will be seniors in a blink of an eye." Jiang Yang suddenly said with emotion.

"It's not so bad. We were single three years ago, and we're still single three years later. Do you think it hurts?"

Zhou Fei shrugged his shoulders, and his tone was not as sad as Jiang Yang's. On the contrary, he was looking forward to life after graduation.

"Brother Fei, stop pretending. Are you having an affair with Chen Yunru from the School of Management? I always see your flirting eyes... You said that if you have a date in the future, what should I do?"

Speaking of this, Jiang Yang's expression became even more lonely.

Otherwise, people who read a lot are prone to hypocrisy. People who don't read much like Zhou Fei don't think so much.

The two were chatting, but Zhou Fei saw from a distance at the welcome office of the School of Management, Chen Yunru, who was wearing a purple school uniform, was waving at him.

Generally speaking, sophomores and juniors are the most enthusiastic about welcoming new students. Although I don't understand why Chen Yunru, who is already a senior, appears here, but being able to see her here, Zhou Fei feels that this trip is not in vain Come.

But he just stood there and waved at Chen Yunru with a smile, but didn't step forward. Zhou Fei is just nobody now, and it won't be too late to show off when he becomes somebody.

After the two of them wandered around for more than ten minutes, they were about to go back to the dormitory, but Zhou Fei received a call from Xu Nan.

"If you have time, come to the laboratory. The testing of the racing car will be completed soon. Let me tell you a few things."

Xu Nan's familiar voice came from the other end of the phone.

"Alright Mr. Xu, we'll be there soon." Zhou Fei replied hastily.

All in all, the testing work of the racing car has been going on for almost a week. According to Xu Nan's initial estimate, the testing work will be completed in three more days.

I just don't know if the key parts of the racing car need major changes.

After explaining the whole story to Jiang Yang, the two soon met Xu Nan in the laboratory.

"In the list of tests you listed, only the brake drum test has not been completed yet, but I have already arranged it, and the results will be available the day after tomorrow at the latest. In addition, here are some data from the previous tests. you can take a look."

As he said that, Xu Nan handed several test reports to Zhou Fei, and his face was full of undisguised surprise, because these test data had completely exceeded his expectations!

Especially in terms of power, the CRT single-cylinder engine equipped with an electronic injection system can be said to have fully improved the performance of this engine to a higher level!
Although the new car of the Jisu team has not been officially released, Xu Nan is not clear about the specific performance parameters, but compared with the performance of the Jisu racing car in the past few years, Zhou Fei has fulfilled his promise, "Design a car that is better than the Jisu team A better car!"
If nothing else, the Mercedes-Benz team will definitely be a dark horse in this year's championship competition!
"Thank you, Teacher Xu." Zhou Fei took the report with a smile, and then read it seriously.

The performance parameters of the experimental report mainly focus on the power performance, especially the off-frame characteristics of the engine. The single-cylinder engine with a displacement of 690CC has a maximum power of 59.8KW and can operate at a speed of 2400~6200 rpm. , to maintain an effective torque output of 85NM, just such a speed range, it is already a ride away.

Not to mention, the minimum effective fuel consumption rate of the modified CRT engine is only 250g/kwh at full load, and its various performance parameters are no less than or even stronger than the 600CC inline four-cylinder engine. At the same time, the engine's The total weight has been reduced by 30 kg!

It has the same performance as a four-cylinder engine, but is lighter and more fuel-efficient than a four-cylinder engine. Once such a single-cylinder engine is put into the Formula Student competition, it will definitely be able to beat all major four-cylinder teams all the way!
Judging from the positioning of the college student formula competition, such performance parameters are already top-notch, not to mention that this is the first time Zhou Fei has participated in the design of a racing car. Although some fine-tuning is still needed in some places, overall the flaws are not concealed. .

In addition to the dynamic performance, the test report also quantitatively analyzed the steering and maneuverability of the car. Including the unfinished braking performance, several major performances of the car have been reflected in the test session.

"I'm bothering Mr. Xu during this time. If there is room for improvement, I will improve the model as soon as possible according to the test report."

After carefully reading these reports, Zhou Fei said gratefully.

Xu Nan smiled and waved his hands, "It goes without saying that I am grateful, the car design was done by you alone, I am just icing on the cake."

Immediately afterwards, Xu Nan was concerned about the team's next training issue, and asked Zhou Fei to pay attention to some announcements recently issued by the competition organizing committee, especially the qualification review of the team.

After a short rest for half a day, Zhou Fei resumed his previous training work in the next two days, while Jiang Yang made corresponding design changes to the car model based on the test report provided by Xu Nan, and for the first time Immediately sent the drawings to Xu Nan.

And two days later, the last test of the car, the brake drum test, was finally complete.

So far, the Mercedes-Benz team has successfully completed the testing phase and can devote 100% to the training phase.
