Rebirth of the Auto Giant

Chapter 18 Class

I have to give a lecture to the armored and engineering soldiers. What should I teach? I need to prepare the lecture.

What aspect should we talk about? Engines are divided into gasoline and diesel engines. Are we talking about diesel or gasoline engines?

From the perspective of the training target, it should be diesel engines, but this needs to be discussed with Uncle Zheng.

Thinking of this, Wang Shi looked at Zheng Qiang and said, "Zheng Qiang, please take me to your father now. I still have some specific issues to discuss with him." This is a government office building, guarded by specialized soldiers.

Outsiders are generally not allowed to enter without permission.

Fortunately, Zheng Qiang, a brother of the General Logistics Department, was there. Soon he came to the fifth floor and found Zheng Wu. He also saw that Wang Xi's father was also there.

"Comrade Xiao Wang, what's the matter with you?" Zheng Wu saw his children coming in with Wang Shi, and knew that Wang Shi had something to do with him.

"Well, I still have some specific things I want to ask Uncle Zheng."

"Please tell me."

"That's right. I want to know what kind of effect you want to achieve with the training you mentioned, and what the content of the training is. The engines are divided into gasoline and diesel engines." Wang Shi said.

"Yes, why did I forget this? Well, our soldiers also use diesel engines. I wonder if you have any problems with this?" Zheng Wu said.

"I have no problem." Wang Shi said.

Next, the two discussed the training, what kind of results it would achieve, the number of people to train, the venue, etc.

Originally, it was temporarily scheduled to be in the auditorium, but considering that there were also some large teaching materials and engines for training, the final training location was decided on a cement field on the left side of the compound. Tomorrow, the arriving engineers will temporarily set up a work shed.

If you do it, then do it well. With the other party's consent, Wang Shi found a scrapped heavy truck made in the Soviet Union, and planned to dismantle it while talking to the soldiers in the training class tomorrow. This would have the best effect.

After doing everything well, Wang Shi took Lei Zi and went back, arriving at the General Logistics Courtyard at around seven o'clock the next morning.

Wang Shi found that his teacher was late. The soldiers were very punctual, and the men in their thirties and forties lined up neatly in the courtyard.

Zheng Wu introduced Wang Shi to everyone and left the rest to Wang Shi.

Some of the classmates were nearly fifty years old. Wang Shi stood in front of the team, looked at the soldiers in front of him, and said briefly: "I was originally here to repair the car over there." After Wang Shi finished speaking, he pointed.

The crown covered with canvas, "The accessories haven't come back yet. Uncle Zheng used this time to ask me to give all the brothers and uncles a professional training on diesel engines. I don't know how professional everyone is."

level, so let’s take it apart and talk about it with the real thing, okay?”

"Okay!" everyone shouted in unison.

"Okay, come on, let's dismantle this scrapped diesel engine now. A few classmates will go over there and push the tripod over with a jack crane." Wang Shi began to enter the role of teacher and began to give instructions.

The soldiers moved quickly, and the two soldiers standing in the front row went over and carried the things over.

The tripod hoist, also called an iron hoist, realizes the lever principle by pulling the iron chain to rotate the sprocket.

There is also a cart.

The training material is a scrapped old diesel car, which can be dismantled quickly. The students here are the backbone of each unit and some have also dismantled the engine. Wang Shi stood aside and guided. Every time he dismantled one, he explained its name and

effect.

In half a day, one engine was disassembled and its systems were neatly placed on the table on the central step of the training shed.

After lunch, Wang Shi rested for about an hour and began to continue training.

The training in the afternoon was about theory combined with practical examples.

"Starting this afternoon, we will conduct systematic theoretical study. Don't worry, our theoretical class is combined with real objects, so it is not that boring. I try to use the easiest way for everyone to understand. If there is anything you don't understand, please let me know.

You must ask questions after I finish speaking, remember that.”

"Diesel engines are divided into two major mechanisms and five major systems," Wang Shi pointed to the words on the blackboard.

Two major organizations:

1. Crank connecting rod mechanism.

2.Gas distribution mechanism

Five major systems:

1. Intake and exhaust system.

2. Fuel supply system.

3. Lubrication system.

4. Cooling system.

5. Start the system.

"The two major mechanisms are the crank connecting rod mechanism and the valve mechanism." Wang Shi stopped here and walked to the ground in front of him to pick up the parts of the crank connecting rod group that had just been removed and said, "This is the crank connecting rod mechanism.

That’s it. We have disassembled and seen these parts this morning. The crank connecting rod mechanism is composed of a piston group, a connecting rod group, a crankshaft, a flywheel and other parts. Its function is to provide a place for combustion and convert the fuel.

The expansion pressure of the burned gas on the top of the piston is converted into the torque of the crankshaft rotation, which continuously outputs power to push the car forward." Wang Shi tried to speak slowly because he found that most of the students were taking notes seriously.

"This big disc is the flywheel. Its function is to provide inertial reciprocating motion. If it's the car over there, there will be teeth on the side of the flywheel. The teeth on the flywheel will mesh with the starter driving gear. When we

When the key is turned on, the driving gear of the starter will stretch out and rotate rapidly to drive the flywheel to rotate together, thereby driving the crankshaft to rotate together and perform work on the piston to start the engine." Wang Shi continued to rotate with his elbow to vividly demonstrate the connection.

How the rod and piston work.

"Does everyone understand this?" Wang Shi stopped and asked.

"You understand."

"Do you really understand? Is there anything you don't understand? Please listen carefully. This training is a test, so if you don't understand, you must ask." Wang Shi discussed it with Zheng Wu. In order to achieve better results, this

After the training, there will be an exam, and Wang Shi will write the test papers himself.

"Ah!" When they heard that there was an exam, the crowd screamed.
