The ups and downs of life in the Siheyuan

For others, being famous may be their favorite thing.

But for Li Yuan, he just wants to live a low-key life and study low-key.

I declined all interviews and invitations and behaved as low-key as possible. When I met curious students from other classes, I just nodded politely.

In the current Huaqing School, students have not yet become star-chasing. After a period of excitement, this celebrity trend has slowly subsided.

However, there is a story circulated in major universities in Kyoto about an art master who gave up art and turned to science.

Vow to make due contributions to the country's scientific and technological undertakings.

At education work conferences, Huaqing University representatives are often the envy of other representatives.

Especially some art schools are jealous to death.

It's soon time for winter vacation.

Li Yuan was left in the laboratory to participate in the final sprint of the parallel four-cylinder engine.

In the past few days, the main leaders of the school have been on duty every day, waiting for the arrival of good news.

After half a year of getting along, Professor Zhang Ran and other senior fellow students in the laboratory have seen Li Yuan's abilities.

Regardless of his theoretical level, drawing ability, or mold manufacturing ability, he far surpasses the veteran technicians in the school's comprehensive machinery factory.

Even other professional high-precision mold production requires Li Yuan to take action.

He readily agreed to these tasks.

If you put in a little more effort now, it will be all about connections in the future.

As the saying goes, relationships get stronger as time goes by, but the premise is that everyone can bring benefits to the other party.

In late January, schools became empty, with most teachers and students on vacation.

But in a laboratory in the Department of Agricultural Machinery, everyone was busy.

After learning about Li Yuan's assembly ability, the engine assembly was moved to the laboratory without bothering the grade 8 fitters in the school's comprehensive machinery factory.

Professor Zhang Ran divided the engine into two major mechanisms and four major systems: it consists of a crank connecting rod mechanism, a valve train, a fuel supply system, a lubrication system, a cooling system and a starting system.

Therefore, the laboratory is divided into 6 groups, each responsible for a task, and each group is led by a teacher.

Now Li Yuan is surrounded by teachers and students in the laboratory.

Whenever a system or mechanism is assembled, the teachers and students in charge will help prepare the parts.

They all have to see their respective results with their own eyes, and the assembly is completed under their noses.

Today is the last day. When Li Yuan tightened the last screw on the top cover, everyone stared at Li Yuan expectantly.

Li Yuan patted the engine lightly and said, "It's done."

Suddenly, a burst of cheers came from the laboratory.

Through the assembly and testing of two unsuccessful versions, these people all experienced the magic of Li Yuan.

As long as it is the parts he promised, there will be no problem. As long as the parts he said were unqualified, even if they were forcibly assembled, Li Yuan was proven right in the end.

Therefore, Li Yuan is now like the judge of this engine.

When he says "it's done," it means that the parts processed this time meet the design tolerances.

Under Professor Zhang Ran's instructions, Li Yuan added water, lubricating oil, and diesel according to the steps.

When everything was ready, Li Yuan retreated into the crowd. Professor Zhang Ran stepped forward, forced himself to calm down, and pressed the start button with his right hand.

Suddenly there was a sound of the motor starting, and the engine made a rhythmic chug when tilted slightly.

Even though black smoke immediately filled the corner of the laboratory, everyone didn't care.

I watched and listened carefully, for fear that the engine would have the same problems as the last two times.

The engine ran for 2 minutes and the sound was crisp and clear without any abnormal noise.

At this time, the entire laboratory was shrouded in black smoke.

Coughing sounds could be heard in the room from time to time, but they were immediately suppressed by the man.

Li Yuan withdrew from the crowd, first opened all the windows on the north side, and then opened all the windows on the south side.

The strong northwest wind turned into a draft and quickly carried away a large amount of smoke.

The teachers and students who were wearing thin clothes suddenly shivered, but no one left here to find clothes.

They all crossed their arms and stared at the engine in front of them.

Li Yuan understood them very well. The first two attempts were started outside the laboratory, and they failed twice, which made them feel humiliated.

This time I tacitly chose to start it in the laboratory, but I was actually ready to fail again.

Even with Li Yuan's guarantee, they didn't want to bet on the possibility.

Li Yuan silently walked to other people's workstations, carrying their coats, and draped them on everyone's shoulders one by one.

Another five minutes passed. Professor Zhang Ran stepped forward and pressed the accelerator. The engine roared suddenly.

Everyone clasped their hands, stared straight into their eyes, and their ears trembled.

This is the result of 2 years of the entire laboratory. It was designed independently by referring to the characteristics of engines in various countries, taking into account materials, costs, and manufacturing difficulty.

In the past, progress has been slow due to insufficient technology accumulation.

Since Li Yuan joined, R&D results have made breakthroughs one after another. Many designs that were difficult to manufacture have been turned over again, partially optimized, and prototypes started to be re-produced.

Li Yuan's various unconventional improvement ideas opened everyone's eyes, and soon there were two prototype tests.

Although they all failed, everyone saw the dawn of success.

Today is the third test run, and it is also the one in which everyone is most confident. It is also the decisive test run.

If this test run is successful, the annual plan for New Year gifts can be completed.

Although we missed the 60th anniversary gift to our motherland, it is of great practical significance to be able to catch up with the th anniversary gift in the s.

Every technological breakthrough can bring a little hope to the suffering people of the country.

The engine continued to roar, the teachers and students had their mouths wide open, and the emotional people had already burst into tears.

Since the relationship with Big Brother broke out two years ago, China has been besieged on all sides.

Many project technical drawings were taken away, and many important equipment stopped being exported to China.

China is burdened by huge debts and has to tighten its belt.

Coupled with the natural disasters in the past two years, the situation has become even worse for the Chinese people.

Now that we have embarked on the road to industrialization, we must bite the bullet and continue on.

Independent invention and technological innovation are the needs of the new era.

The successful development of the parallel 4-cylinder engine marks that China has a high-horsepower engine with independent intellectual property rights.

Professor Zhang Ran released and closed the accelerator, and the engine slowly stopped running.

When Professor Zhang Ran announced the success of the engine development, there was even louder cheers in the laboratory.

Some people ignored the cold wind and threw their clothes up to the ceiling.

Li Yuan silently closed most of the windows again, leaving only one window on the far side, one in the north and one in the south.

The main reason why he's so calm is because he has a better engine in his head.

This time he just showed off his abilities a little bit, so that everyone would recognize him and trust him. Next, he wanted to use laboratory resources to turn the engine in his mind into reality.
