Following an order from Factory Manager Wang, the six contestants immediately started to fight.

In the repair shop outside, there is often only one master craftsman who disassembles and overhauls the engine, dismantles the engine into parts one by one, and then reassembles it. There is not a single part left, which is called a cow.However, it usually takes a day or two to complete.

Now, to quickly assemble the parts of the engine into a complete engine, it not only needs to test the proficiency of the installer in the engine, but also considers the close cooperation of various processes. After all, there is only one person. If an overall plan cannot be made, it is very likely that there will be a serious delay in a certain process.

According to the standard procedure, the cylinder body should be installed first, but the experienced Sun Bingwen did not touch the cylinder body, but quickly put the four pistons into an iron basin, put water in it, and then, Some inflammables were stuffed underneath, and a fire was lit directly on the spot.

The Santana engine uses a fully floating piston pin, so it will be difficult to install it in a cold state. Therefore, even if it is installed in a regular workshop, the piston pin must be preheated first, and the piston will be affected. Thermal expansion, at this time, it is easy to install the pins inside.

This preheating takes time. In order not to be delayed by this step, Sun Bingwen first chose to heat the piston.

At the same time, this is also a preset program. There is such a heated table next to each player.

Sun Bingwen finished all this quickly, and then glanced at Qin Shaoyou, and saw that Qin Shaoyou had already lifted up the cylinder block of the engine, and was cleaning the cylinder block with compressed air from the side, and the German consultant Carl, actually treated Qin Shaoyou This action expressed satisfaction and nodded repeatedly.

The cylinder body is cast, so it is inevitable that it will not be cleaned cleanly. Qin Shaoyou first cleans the cylinder body with compressed air. This step is very important and is easily forgotten by ordinary people.

Qin Shaoyou finished cleaning the cylinder easily, and then began to install the cylinder liner.

The principle of the engine is very simple. The piston moves back and forth in the cylinder to transmit energy. Later engines have advanced technology, and a layer of wear-resistant coating is directly sprayed inside the cylinder to make the piston move back and forth.But there is no such thing in this era, so the cylinder liner will be embedded in the cylinder block, and then the piston will move back and forth in the cylinder liner.

The installation of this cylinder liner is also very particular. A slight deviation will cause partial wear of the piston inside, and failures such as oil leakage are appropriate.

Now, Qin Shaoyou installed the cylinder liner as soon as he came up, which confuses everyone. The piston and connecting rod should be done first!

Carl opened his eyes wide, watching Qin Shaoyou's operation, and saw that Qin Shaoyou took out a unique tool from the box brought under his feet, and quickly fixed it on the cylinder with a few screws.It's like adding an extra shelf to the steel, the space in the middle is just enough to accommodate a cylinder liner.

Qin Shaoyou put the cylinder liner on the first cylinder, and then measured it with a caliper a few times. After fine-tuning, he turned a crank handle next to it, and the gears drove over, and a push-pull seat on the shelf just swished like this With a downward movement, the cylinder liner is easily tucked into the cylinder.

The onlookers were amazed.

"What is that? Why have you never seen it before?"

"That's right, can you still install the cylinder liner like this? If the repair shop outside has such a set of tools, it will be much easier to overhaul the engine!"

"Hmph, grandstanding, if it's really a repair shop outside, it's so troublesome to use. With a wooden plank, it can be hammered in with a few sledgehammers. I guess Master Sun will do the same in a while."

"What do you know, can a few sledgehammers be knocked in, can the accuracy be guaranteed? Have you seen it? Qin Shaoyou pressed a few times and measured it. The accuracy is absolutely no problem. No wonder it can arouse the interest of German consultants. This Qin Shaoyou may not be sure. For a few moments, I'm a little optimistic about him."

The first cylinder liner was installed, followed by the second, third, and fourth, and when all four cylinder liners were installed, Karl couldn't help but said, "Qin, I can see this set." Tool?"

Qin Shaoyou glanced at him: "It's okay to look at, don't delay my work while watching."

So, Karl finally held back: "Forget it, I can't delay watching your operation."

Carl was very interested in that set of tools. As an excellent engineer, he saw the benefits of this set of tools at a glance: not only can the cylinder liner be installed, but also the cylinder liner can be disassembled. The structure is simple, easy to use, and saves time and effort. It also ensures that the accuracy requirements are met.Although it can't be used in the car factory, it is really easy to use for maintenance in the subordinate 4s shop, or for maintenance work in the field!

Its structure is also very simple, hand crank, pressure seat, screw sleeve rotating seat, upper plane bearing, lower plane bearing, positioning screw, limit nut, push-pull seat and pressure rod...The positioning screw is threaded on the cylinder body , to fix the entire tool, the screw thread of the positioning screw is connected to the limit nut, and the screw sleeve rotating seat with an I-shaped cross section runs through the pressure seat...

Karl had never seen this set of tools before. At this time, he was an eye-opener. He had already seen that Qin Shaoyou was not easy to come. what else baby

After it's over, it's not too late to discuss these things with Qin Shaoyou. As for now, he will continue to watch Qin Shaoyou assemble the engine, and then it's time to install the crankshaft.

On the other side, Sun Bingwen glanced at Qin Shaoyou's direction and saw the German consultant nodding repeatedly. At this time, Sun Bingwen's face was also a little ugly. He grabbed a cylinder liner and put it on the cylinder body. sledgehammer.

Boom, boom, boom!

With three hits, a cylinder liner was smashed into the cylinder block, the action was very skillful.

Before the Santana car was introduced, the Automobile Factory in S City was also producing other cars. Those cars were almost all hand-assembled. The cylinder liner was originally smashed in by a master craftsman without more than ten years of experience. It's not a good job at all.

A young worker like Qin Shaoyou is only worthy of a little cleverness. If you want to talk about real skills, you have to look at a master like yourself!

Sun Bingwen picked up the second cylinder liner in his hand, put it on the second cylinder, and then continued to swing the sledgehammer.

Boom, boom, boom!

Carl turned his head and glanced, then shook his head helplessly.
