Siheyuan starts from a good life

"Uncle Liu, do you think it's time to conduct a test?"

Jiang Yan patted Director Liu, who was lost in thought while touching the engine.

Jiang Yan's slap completely brought him back to his senses.

He hurriedly said: "Yes, yes, I want to test it. Whoever it is, hurry up and get a barrel of gasoline."

Xu Damao, who was following Jiang Yan, heard Factory Director Liu's words and said, "I'm going to get gasoline." After saying this, he ran out.

Jiang Yan saw that the secretary following Director Liu seemed to be half a beat behind Xu Damao. When he saw Xu Damao running out, he just opened his mouth.

"Here comes the gasoline." Xu Damao trotted over carrying a small bucket of gasoline.

Director Liu took the gasoline from Xu Damao's hand and called Jiang Yan to pour the gasoline into the new engine.

At this time, the workers in the workshop gathered in a circle. After so many workers worked hard overnight, it was finally time to test the results.

Jiang Yan started to light up the fire under everyone's gaze.

After the fire started, Jiang Yan pressed the accelerator, and as the gears inside rotated, the engine started to start with clear smoke.

As the engine started working, everyone was stunned for ten seconds, and then burst into enthusiastic applause.

Then someone was heard shouting: "We succeeded, we succeeded."

"Xiao Jiang, is this a success?" Director Liu seemed extremely excited at this time, pulling Jiang Yan's shoulder and asking.

"That's right! But this is just a preliminary test. The engine still needs to be installed on the car. It needs to undergo a series of road tests such as hill climbing and swamps, as well as severe cold and high heat tests. Only after passing all these tests can the engine be finalized. .”

In fact, there are four main steps in the formal method of testing an engine.

One is the fuel supply test, which is one of the most basic tests in the calibration test and is used to determine the fuel supply required by the engine.

The second is the air intake test, which is a test used to determine the air intake required by the engine. Through these tests, you can ensure that the engine's air intake is optimal and improve the engine's efficiency.

The third step is the ignition advance angle test, which is a test used to determine the engine ignition time. Through these tests, you can ensure that the engine's ignition time is optimal and improve the engine's combustion efficiency.

The fourth part is the exhaust resistance test, which is a test used to determine the resistance of the engine exhaust system. Through these tests, the normal operation of the exhaust system can be ensured and the exhaust resistance can be optimized.

However, such testing requires the use of specialized equipment and even the construction of a specialized large-scale laboratory. Obviously, the country does not yet have this capability, and can only adopt relatively simple testing methods.

"I'll arrange the vehicles right away," Director Liu said as he prepared to leave the workshop.

Jiang Yan caught him immediately and said, "Uncle Liu, do you want to report to Minister Liu Xufeng for the next step of testing?"

Hearing Jiang Yan's words, Factory Director Liu woke up from a dream and slammed his head, "Look at me, I'm so happy that I want to announce the good news to the leader. In this way, let's test all the other remaining engines to make sure Once everything is correct, I will call Minister Liu to report the good news."

After Jiang Yan's test, eight of the ten installed engines successfully ignited. Of the two engines that failed to ignite, one failed to ignite due to a gap in the cylinder during molding, and the other had an air tightness problem. , even this success rate was far beyond Jiang Yan's expectation.

It was already daybreak, and the workers were already a little tired after working all night. Seeing this situation, Director Liu arranged for the workers to rest nearby, but he took his secretary to the First Machinery Department to report.

"Boss, Director Liu called just now. The machine department will be here in another 20 minutes. Please prepare."

Jiang Yan, who was resting on the camp bed, was woken up by Xu Damao. After hearing Xu Damao's words, Jiang Yan quickly got out of bed, tidied up, and walked to the first workshop with Xu Damao.

When Jiang Yan arrived at the first workshop, almost all the workers from last night had arrived, and everyone was waiting for Jiang Yan.

Seeing these workers, Jiang Yan waved his hand and said, "Start making according to the process arranged last night."

After everyone responded, they dispersed, walked to their workstations, and began to get busy.

Jiang Yan turned to the two apprentices who were following him and said, "You two also saw the installation steps last night. After you have been given a tour, you two will get started. I will assist you."

"I can explain it clearly to you two. I will teach you step by step the installation process without any reservation. If you don't know, you can ask until you learn it. But you two, please remember one thing. In the future, you will train technology People, please don’t let me play with these things.”

The two people heard Jiang Yan's slightly harsh words and spoke quickly.

"Don't worry, master, we won't hold anything back."

Jiang Yan nodded after hearing what the two people said.

In the past, masters often left one hand behind when teaching their disciples. This was the traditional concept of "teaching apprentices to starve the master to death." Under the control of this concept, many craftsmanship was not refined or even lost.

Of course, Jiang Yan didn't completely disagree with this "hold on one hand" attitude.

If it were his own world, Jiang Yan would definitely not impart his knowledge to his apprentices without reservation. In fact, the reason is very simple, just for survival.

From the perspective of the times, it is understandable to govern the country according to the law, protect the legitimate rights of citizens, and pay attention to contributions as well as rewards.

In the era of market economy at that time, cultural industry policies were also introduced, and knowledge became a commodity. Some professors paid tens of thousands of yuan for a class, which was normal. What about the master who teaches skills? Of course, you can't suffer any loss, so you can teach your disciples without any reservation, forming a good momentum of "a young person is better than a good person". Unfortunately, this good momentum has not yet formed, and the phenomenon of "teaching apprentices to starve their masters to death" continues to this day. It is not surprising that the masters protect themselves and "save a hand".

But this is the era of planned economy, and accepting disciples now is not the same as in later generations.

Nowadays, the tradition of accepting apprentices is still maintained. Apprentices are all carefully selected and only accepted if they think they have potential in this area. If they think you don't have this potential, they will be accepted no matter how much money you pay.

Before accepting apprentices, the master will inspect these apprentices for several years.

When you learn skills from a master and meet the master, you need to prepare a meeting gift. In addition to wine and meat, some people also prepare red envelopes or gifts. After being introduced by the introducer and interviewed by the master, if you are satisfied with the gift, the master will accept the gift, otherwise you will refuse it. After the master receives the gift, the student will kneel down and kowtow to express his gratitude and pay homage to the master. Some even set up a table to light candles and pray to the ancestors and gods. After that, the master also signed a learning contract with the apprentice, clarifying the obligations of both parties. Most of them were stipulations for the apprentice, such as the apprenticeship period was three years, no wages were paid during the learning period, and they had to be diligent and not be lazy.

Wang Dabao and Liu Yong also proposed to give Jiang Yan a thank-you banquet when he came back. However, after being rejected by Jiang Yan, the two of them are still a little uneasy.

And once a disciple is accepted, the requirements for the disciple are also extremely high. If the apprentice is found to be lazy and slippery during the learning process, the punishment may range from a scolding to a severe fasting for a day or a meal. The apprentice's potential coupled with the master's strict education allows the apprentice to learn a skill that he can use throughout his life. Therefore, the apprentice is also very grateful to the master.

What's more important is that today's factories are all state-owned factories. Although they have their own shortcomings, at least they will not fire workers at will like private factories in later generations.

Workers are the absolute protagonists of this era.

There is another update before and after, but it is a little later. Muyu has just returned to the dormitory from the mountain. Thank you everyone.
