Wan Feng listened to Master Luo Zhongxing's introduction to the engine.

"This engine has a total of 1,560 parts, including 563 parts with low production difficulty, 891 with medium production difficulty, and only more than 100 parts with real difficulty. ”

"Of course, we can't rely on our own production, we can't do everything professionally, we can't control the production cost by ourselves, and we can't enter the market at all. Therefore, we have to contract all the parts with low processing difficulty to professional factories to do, leaving only a few key things to manufacture by ourselves, and then we can get the parts back to assemble, which can not only speed up the progress of production but also greatly save costs. ”

Luo Zhongxing nodded: "Then we will specialize in producing a few of the most difficult things, so that others can't produce them, and others just have to imitate and overcome these technologies." ”

This is also a trick to guard against lazy people, with the technical content of the 50 engine, if someone really wants to tinker, it is really not a difficult thing.

"How long did it burn when the No. 1 was ignited?"

"The No. 1 unit was ignited twice, the first ignition worked for one minute and fifteen seconds, and the second ignition worked for five minutes. ”

"Extinguishing the fire yourself?"

"No, it's when we find a problem and put out the fire and then check it. ”

"What problems did you find?"

"The first phenomenon of overheating of the organism, we found the cause and ruled it out, and then carried out a second ignition, and after five minutes of operation, there was a problem with the carburetor, which has now been ruled out. ”

"So now we should do a third test drive to see if it can work for ten minutes and what problems will arise. ”

The No. 1 machine was started for the third time, and the engine made a sudden working sound.

Technicians nervously stare at the working engine.

One minute, three minutes, five minutes...

This time, the engine worked longer than the previous two times, until the engine worked for about eight minutes, and the body overheated again.

Luo Zhongxing immediately decided to stop the order.

This time, it took a long time to find the cause, and after nearly a morning of tireless efforts, it was finally possible to find out the cause of the overheating: the problem was with the piston ring.

Although the specifications of the piston ring of Master Luo's own eye grinding meet the standard, the metal material is not matched correctly, and the phenomenon of overheating and deformation will occur after a long working time.

They are not specialized in the production of this thing, which requires a professional counterpart.

"We have to find a professional manufacturer to solve this problem. This is Luo Zhongxing's suggestion.

At that time, the manufacturers of piston rings included a manufacturer in Liaoyang and a manufacturer in Shijiazhuang.

The piston ring produced by Liaoyang manufacturer has low cost, but the wear resistance is not good.

Shijiazhuang factory piston rings are of high quality, durable is the common choice of many engines at present, and the piston rings used in the single cylinder 195 of Wahou Machinery Factory are produced by this factory.

However, the Shijiazhuang factory certainly does not have the piston rings used in this 50 engine, because this thing is only produced by the Jialing factory now, and they cannot go all the way to Shijiazhuang to order piston rings.

In this way, Shijiazhuang needs to make new molds, and when people don't know the scale of the product, they may not be able to make them.

"Master Luo, it seems that we have to go to Shijiazhuang. ”

Wan Feng decided to go to Shijiazhuang with Master Luo in person, at this time he had to go out, when he had money, he had to show the power of money, and by the way, he wanted to go to Qindao to do some private affairs.

The motorcycle engine was temporarily put aside, Wan Feng pushed Luan Feng's motorcycle over, and a technician took over the motorcycle and replaced the front wheel.

"What about the 1105 and 1115 engines now?" Wan Feng asked the two eighteen- and twenty-five-horsepower single-cylinder diesel engines.

"It has completely passed the state inspection, but we don't know what it is supposed to do now, and only a small amount has been produced and it has been technically mothballed. Xiao Dexiang explained.

"Don't worry, let me think about it, what should I do with them, when the engine of the motorcycle is successfully studied, we should study the four-cylinder engine next. ”

Of course, the two single-cylinder high-horsepower diesel engines are used in large-tonnage agricultural tricycles.

However, if this agricultural tricycle is put into production, it will inevitably have an impact on the four-wheeled wheels, and the four-wheeled wheels of the machinery factory are now in short supply, and there is no need to put into production large-tonnage tricycles for the time being.

Let's make technical reserves for two years first.

Anyway, those in Dongshan Province don't know where the whirlwind is blowing now.

"We have been studying according to the working principle diagram you drawn, and the body has been cast, and the accessories that can be purchased have been bought, and we are ready to produce the parts that are not sold, and we have already stored eight or nine of them. ”

Wan Feng was once again shocked by the enthusiasm of these people.

These people are working on the 50 engine at the same time as the four-cylinder diesel engine? What kind of spirit is this?

Is this wholeheartedly for the yuan... The spirit of serving the people?

At this moment, Wan Feng suddenly felt that it was time for his mother to go out to find her two aunts and brothers, and it was time to come back.

He is inspired by the working environment and the enthusiasm of the people.

If it weren't for the talents he was thinking about and some of the skills he wanted to get, he would have wanted to come back now.

It's a good place for people to do something.

The front fork and front wheel of the motorcycle were quickly replaced, and Xiao Dexiang also rode out for a lap, and when he came back, Wan Feng was already studying the electric fan.

He was working with someone in the technical department on how much coil to wrap as a starting source for the fan.

It didn't take long for a fan without outer packaging to be successfully made, and the fan fan was connected to the power supply and the fan was brushed up.

Although the workshop can block the shade, but it can't block the heat, with such a thing, everyone makes do with the fan.

"It's better to produce this thing, it's so easy to produce, why don't we make some and sell it?" asked a technician.

Wan Feng said: "I'm afraid it's too late this year, it's the end of July, what we produce and pass the inspection will probably be autumn, next year we can set up a special electrical factory to produce these things, now you are idle to study and play, but if you want to take it out and sell, so that you will not shake your head and will not be able to adjust the wind speed from time to time." ”

"That's not a problem, we can't shake our heads, we can make a little mechanism to do it, and as for the timer, isn't that the kind of timer on the washing machine done?" suggested another technician who had seen a washing machine.

"Do we also have to study the washing machine, it seems that there is a motor under that thing, and it is not a big deal. ”

It's okay that the technician didn't suggest, and as soon as he did, these people started to think about the washing machine again.

Wan Feng hurriedly took the fan like a skeleton and rode home on a motorcycle, and after sitting here for a while, they might be making something again, these guys seemed to have become manufacturing maniacs.
