1959: Carrying the achievement system, she rolled

Two days later, the three teachers and students in the second laboratory looked at the iron lump in front of them with blank expressions. This was the engine they made.

Both its performance and reliability are excellent, far exceeding the B2 series V-type 12-cylinder water-cooled diesel engine.

It can be said that this is a technological breakthrough, which has not let down their hard work overtime during this period. The three of them should be very happy.

Especially Qin Chulong, he was reluctant to stay at home for a few more days even when his wife gave birth, and devoted all his attention to the engine.

But looking at the expressions of the three people now, it seems to be just the opposite.

The volume and weight were within the standards, but the effect they wanted was not achieved.

Because only when the power room takes up less space can the burden on the tank be reduced.

"Any ideas?" Qin Chulong asked.

"No idea!" Wan Ping replied subconsciously. To be honest, being able to manufacture an engine with a simple structure and reliable performance is already a huge improvement for him.

He feels very awesome about himself, but his current state is just like that of martial arts training, where he has reached a bottleneck and it is impossible to break through for the time being.

When he came to his senses, he subconsciously looked at Qin Chulong, wondering if the teacher would be disappointed in him?

Qin Chulong on the opposite side didn't even give him a consoling look, his eyes were always on Du Yimeng.

Wan Ping curled his lips. When they were in college, he was obviously the teacher's most satisfied student. He didn't know when the teacher started to change his mind.

Is it because he doesn't work hard?

Do not……

Du Yimeng is too abnormal!

"Teacher, I think this engine still has room for improvement." Du Yimeng's eyes were always on the engine, and he replied after thinking for a long time.

"Tell me!" As soon as Qin Chulong finished speaking, Wan Ping quickly took out a pen and paper.

Qin Chulong couldn't help but turn his head and look at Wan Ping. He had to say that this student was stupid, but sometimes he was also very smart.

"The water cooling system can be improved. If the cooling cycle and radiator are removed, can the weight of the engine be greatly reduced?" Du Yimeng asked Qin Chulong with sparkling eyes.

You should know that the water cooling system uses liquid to absorb heat and then dissipates it through the radiator, which requires more components to form a complete cooling cycle.

If you remove the water pump, coolant pipes, radiator, etc., you can definitely reduce the total volume?

"Without these, the engine's life will be extremely short. By then, even the new tanks will become a pile of scrap metal. People who don't know will think you are in cahoots with the enemy!" Wan Ping retorted.

If such an engine is installed on a new tank as she said, it will be laid down before the enemy can attack it on the battlefield. How can we fight?

After putting in so much effort, I get the same result. Why struggle? I might as well just lie down from the beginning.

"Student Du, please refute it." Qin Chulong took off his dirty gloves while speaking. For some reason, he always felt that Wan Ping was targeting Du Yimeng these two days.

Wan Ping had always followed her lead before, but it seems that they have fallen out.

When Du Yimeng heard this, the corners of his mouth twitched subconsciously.

Wan Ping had been like a woman every month, with a few unhappy days these past two days. He had said that he was going to break up with her that night, but the next day he took the initiative to talk to her.

She had already generously forgiven his childishness, but he would always say something mean to her.

If he continued to be so ambivalent, she would be worried. She was afraid that their relationship would change from classmates to sisters.

"I just said that we are improving the water cooling system. Please bring your ears with you when you come to the laboratory. Don't wear two big eyes all day long and glare at everyone you see." Du Yimeng said with a sneer.

Wan Ping subconsciously shrank his neck. He felt that Du Yimeng was quite scary like this.

But he immediately stretched out his neck again, determined not to give in to her tyranny.

"We can spray the coolant directly on the parts that need to be cooled, and then use the air and gas to quickly remove the heat. In this way, there is no need for a special cooling cycle and radiator. Can we reduce the volume and save more space for the power room?" Du Yimeng continued after arguing with the man.

"I think your idea is feasible!" Qin Chulong nodded in agreement, and Wan Ping beside him also nodded.

Maybe he felt that this was a bit inappropriate, so he looked at the two of them with an awkward expression, but when he saw that no one paid any attention to him, it seemed that he was being a little too self-indulgent.

"There's no rush for this matter. Let's go to my house for dinner later." Qin Chulong said again.

"Teacher, I like to eat in the cafeteria." Wan Ping refused directly. The teacher's wife is in confinement after giving birth, so who will cook?

It must be the teacher. The teacher's cooking skills are not as good as his. The taste of the big pot rice is not very good, but at least it won't kill you!

"Student Du, remember to come to my house for dinner." Qin Chulong said this and was about to return to his office, but when he passed by Wan Ping, he glanced at the latter out of the corner of his eye.

Director Song told him privately that the reason why Xiao Miao confessed everything was because of Du Yimeng's help.

The person he wanted to invite for dinner tonight was Du Yimeng, firstly to thank her for her help, and secondly to ask her to help him look for someone else.

If he were to be honest, he was not as good as his students in judging people.

As for Wan Ping, he just brought it along. It doesn’t matter if he doesn’t eat it. He can save food!

It would be fine if this idiot didn't know how to appreciate kindness, but he actually despised it. Humph...

"Teacher, what's that look?" Wan Ping asked in confusion. Was his refusal obvious?

Or was it that his little thoughts were discovered by the teacher, which is not right?

"What else could it be? Of course it's a look that means he's ready to make things difficult for you." Du Yimeng sneered at Wan Ping, then returned to his office. Of course, he left the rest of the work to him.

"I..." Wan Ping was puzzled. He just refused to eat, so why was the teacher like this?

……

After get off work, Du Yimeng went straight to Qin's house. Not only was Captain Hao following her, but also Wan Ping, a follower, but she was too lazy to pay attention to him.

When asked to go out for dinner, he refused in person.

After refusing, he still wanted to go.

She could understand all of this, since he was a person with abnormal brain circuits. The only thing she couldn't understand was why he still looked so reluctant?

Does he know that he can easily be beaten to death like this?

"Auntie!" Du Yimeng came to Qin's house and went straight into the kitchen. Seeing Sister Song busy in the kitchen, she hurried forward to help.

Wan Ping, who was following behind her, saw Mrs. Song busy in the kitchen. His eyes suddenly lit up, and then he looked at Du Yimeng with resentment on his face.

She must have known it all along, but she didn't tell him anything. She is so mean!
