Chen Geng said that in fact, I have fully taken into account the current actual situation: "What you said is, so taking into account various actual conditions, the engine I designed is two-stroke, 100CC displacement, in the design also considered our existing domestic material level and finishing capacity, the possibility of making a finished product is quite large, now the difficulty is that we are a maintenance plant, can only do some simple processing and heat treatment, without any experience in production, manufacturing, assembly of engines, There is also a lack of experience and technology in finishing, and there is no way to assemble a machine in small batches to test the performance, so teacher, can you come over and serve as our technical consultant in engine crankshaft manufacturing? ”

This guy has finally come to the fore.

In addition to being a designer, Chen Geng, who is also an engineer, of course understands machining, but Chen Geng understands CNC machining, using the technology of parts processing with this ordinary machine tool in China, Chen Geng has fallen for decades, under the current conditions of the current technical level of processing workers in China, his CNC machining program programming ability is basically useless, Chen himself is really not sure that he can process a qualified high-precision parts under the current industrial conditions in China, the only way, It is to invite these skilled old technicians to come out.

But Xia Shifu's shocked eyes even protruded: "You have finished the design according to the industrial and material conditions of our country?" ”

The point of his surprise is not that Chen Geng completed the design of a 100CC two-stroke gasoline engine, but the two keywords of 100C and two-stroke: as a practitioner in the domestic engine manufacturing industry, Xia Shifu heard that Changling Group introduced a motorcycle from Suzuki Company of Japan, and the model is not clear, but this motorcycle seems to be equipped with a 100CC two-stroke engine.

Could it be that Chen Geng "designed" that Suzuki's two-stroke engine?

"There are indeed places to borrow from the Suzuki AX100 engine, but there are many improvements and adjustments in many places." Chen Geng did not deny this.

As a generation of classic two-flush gasoline engine, Chen Geng really knows the detailed design information of AX100.

Is there a problem with asking Chen Geng to design a completely new engine? Of course, no problem, if you don't take into account the current domestic processing capacity, he can even make this 100CC engine burst out with a maximum power of more than 40 horsepower, but is this useful? The design does not mean that it can be made, and the industrial base and processing capacity are not taken into account when designing, and in the end, the design can only stay on paper.

A few years later, there was such a statement on the domestic military forum, which roughly said: "In fact, our country's aero engine designers are very powerful, and they can design a world-class aero engine, which is more powerful than the F119 of the US imperialists, but we can't do it, and our industry can't do it, so it's dragging its feet."

But in Chen Geng's view, this is a hooligan.

Let's not talk about the credibility of this statement, whether a domestic aero engine designer who has little background and accumulation in the field of aero engine technology, who has not seen the world's top aero engine designers, and how design institutions work, can really design the world's top aero engines (even if it is just a parameter on paper), but as a designer, Chen Geng wants to scold his mother every time he sees such words: any designer must have a premise when designing a certain product, That is, after comprehensively considering all the factors that may be hard to come, such as cost, material base, industrial base, heat treatment capacity, and finishing capacity, we can start to make design, rather than patting my head and saying that my design is going to do this, and then I don't care whether the country's industrial base can process this part - anyway, my work has been completed, I don't care if you can make it, whether you can do it is your business, and it has nothing to do with Lao Tzu.

Every time he sees similar arguments, Chen Geng feels that the big **** is too preferential to military designers, if it is a designer of a foreign company, he dares to be so arrogant and willful, "Anyway, my work has been completed, can I make it and have a woolen relationship with Lao Tzu?" You don't have to wait until the next day, you have to pack up and get out of the bed in less than half an hour! The capitalist is very realistic, Lao Tzu pays you a salary to let you help Lao Tzu make money, not for you to be an uncle, arrogant, right? Where do you love tsundere, where do you die, a large number of designers who are not tsundere are waiting to be exploited by Lao Tzu!

Well, this is a bit far, and when Xia Shifu once again confirmed that Chen Geng was not joking with himself, he had to accept this answer that seemed a little ridiculous.

But then, the old man was relieved, and even felt that he was making a fuss, Xiao Chen is a top student of the Department of Automotive Engineering of Huaqing University, there is a reference prototype, is it difficult to design a simple 100CC two-stroke gasoline engine?

He didn't know that the current Changling Group had not yet obtained the drawings of the AX100.

More than these, the characteristics of the profession make him more concerned about the performance of this engine.

"DISPLACEMENT 98CC, 4-speed transmission, maximum power 7.4 kW......"

This number is slightly higher than the AX100's 7.3 kW.

"74 million?" Old Man Xia was surprised: "Really? Our happiness 250 is only 7.3 kilowatts, right? ”

He was surprised with reason: the happiness 250, one of the only two "large displacement" motorcycles in China at this stage, is equipped with a 250cc single-cylinder two-stroke engine, and the maximum power is only 7.3 kilowatts, and the engine designed by Xiao Chen is only 98CC displacement, and the maximum output power is even more powerful than the happiness 250?

"It's true," Chen Geng nodded: "In addition, I have specially designed a set of engine oil system, there is a special oil pot, which can store 4.5 liters of engine oil, and there is a special oil pump to inject oil into the mixture, so that there is no need to mix oil into the oil tank like the current two-flush gasoline engine in the future......

The current domestic two-stroke gasoline engine, such as Jialing 50 and Qingqi 15, all need to be mixed with special oil for two-stroke gasoline engines in the fuel tank according to a certain proportion.

Of course, Wolfsburg's "gasoline-oil" hybrid engine does not need to prepare an oil pot and oil pump, and people's technology is more "advanced".

The old man nodded again and again, and admired Chen Geng's design: "This design is good, with this separate oil pot, you don't have to carry a bucket of oil to mix oil when you go to refuel in the future, it's too convenient." ”

"But in this way, the problem is back to square one, we don't have any experience in producing engines, machining parts and assembling," Chen Geng looked at the old man pitifully, and folded his hands: "Teacher, will you come and help me?" ”

After speaking, Chen Geng patted his head: "Look at me, I can't let you help us in vain, let me tell you about the conditions for our company to hire consultants: for technical consultants like you, in addition to arranging housing, the consultant fee is 200 per month, and the bonus varies from month to month, but it will not be less than 20% of the salary and there is no upper limit, 14 months of salary will be paid every year, and there will be New Year's festival expenses and benefits;

In addition, if an out-of-town consultant like you has 4 days of home leave every month, the travel expenses will be reimbursed at a rate of 150%, and if the child comes to see you, the same reimbursement rate will be made. ”

150% reimbursement ratio, this is easy to understand, in addition to the travel expenses, there is always something to eat on the road, and it is not easy to go back home, always buy something for the family, right? That's 50% of the extra for this.

Aunt Ren, who had been sitting next to her and talking to the master and apprentice, immediately felt a little moved when she heard these conditions made by Chen Geng.

Although their family is a double worker, there are not many children in the family, only two, the eldest has started a family, the second is a temporary worker in the factory, the second child will be able to take over the old man's class immediately, there seems to be no pressure at home, but in fact it is not the case, a family of six lives in this more than 30 square meters of house, the pressure of housing is very great, the eldest daughter-in-law has been talking for a long time and said that she wants to go out to rent a house to live.

Also, Aunt Ren can understand the thoughts of her eldest daughter-in-law, and now this housing condition, a family of three is a bit too small, let alone a family of 6 and three generations? The young couple even have to be sneaky to live a little married life, and it feels uncomfortable to think about it.

If you and your wife go to work in other places, not to mention letting your children rent a house, at least you can free up some time to make the children live more comfortably, and the money in your hand can also help the two children, and by the way, save some money for the second child...... If it is like before, the son takes over Lao Tzu's class, and the old couple relies on that pension, and the second child will be in trouble when he gets married.

Pushing Master Xia, Aunt Ren said: "Lao Xia, you have just passed 50 this year, and you have at least twenty or thirty years to live in the future, are you going to raise flowers and grass in these twenty or thirty years?" Xiao Chen is your apprentice, how many times have you told me that this child has spirituality? Since your child needs your help, you can go and help him. ”

Of course, Xia Shifu was also excited, but at the same time he was a little hesitant: "But what I'm good at is crankshaft machining, and I don't know much about the rest." ”

"Teacher, in addition to you, I also plan to invite some masters to go over with us in our factory, oh, by the way, although the conditions of our company are still relatively difficult, the company's profitability is very good, and the number of vehicle modifications every month is hundreds, so I plan to build a few houses, if you are willing to sign a 5-year consultant contract with us, you two old people go over together, Aunt Ren's work I want to find a way to solve, at the latest half a year, you will be assigned a 2-bedroom and 1-living room house."
