Chen Geng groaned, thinking about how he should answer this question.

"First of all, of course, we can purchase engines from your unit to run this project, but the weight of the Yangtze River 750 is only more than 300 kilograms, and the weight of the Fiat 126P is 600 kilograms, if the XJ750 engine is used as the power of this family minicar, some parameters of the engine need to be adjusted and rematched, which takes a lot of time, but Xiangjiang Engine Factory has produced this engine for twenty or thirty years, and has rich experience in how to debug and match this engine. If we can count on your support in terms of engines, we can better focus our efforts on the whole vehicle. ”

"Yes, it is." Huo Dongfang agreed with Chen Geng's statement, but he thinks that this reason is not enough, as a company that can independently develop a high-performance motorcycle engine, it is not a difficult job to rematch and adjust the XJ750 engine, he needs Chen Geng to give him a better reason: "What else?" ”

Do you want to say it? For the second reason, Chen Geng was a little embarrassed.

But after thinking about it again, Chen Geng still decided: Say! Even if you don't say it, the other party will know sooner or later, since this is the case, then simply said directly: "Don't hide a few, our unit is improving and upgrading the performance of the XJ750 engine, Xiangjiang Machinery Factory has a lot of experience in the XJ750 engine, we sincerely hope to get the technical support of Xiangjiang Machinery Factory......"

"Are you working on the XJ750?" Without waiting for Chen Geng to finish speaking, Feng Hua asked curiously, "How did you change it?" Can you tell me about it? ”

"Of course it's no problem," Chen Geng nodded. Next, we need technical support from Xiangjiang Machinery Factory. Of course, this level of R&D content is not a problem: "The main thing is the optimization and beautification of the external styling of the engine, the improvement of the strength of individual performance parts, and the improvement of the level of power output......

"You're planning to increase the output of the XJ750 engine?" As the chief engineer of the XJ750. Feng Hua was suddenly excited, as the chief engineer of the XJ750 engine, Feng Hua is definitely one of the people who know the most about the XJ750 in China, but it makes Feng Hua feel regretful, although he also knows that the improvement potential of the XJ750 engine is very large, but limited by funds, as the chief engineer of the XJ750 engine, he has not made any improvements to this engine, which is not only a pity. It's even more shameful, now that he heard Chen Geng say that they Runhua Industry is now improving the XJ750, how can he bear it? I was almost impatient: "Manager Chen, where have you been?" ”

"Our goal in the first phase is to increase the maximum output of the XJ750 to 32 horsepower, and the maximum stable speed to 4500 rpm.

The second step is to increase the maximum output to 40 hp and the maximum rev to 5500 rpm. Now we have raised the maximum stable rev to 5200 rpm, which is an optimistic estimate. By next summer, it is expected to enter the stability testing phase;

The goal of the third step is to increase the maximum output to more than 50 horsepower within one year......"

"It can't be!" Before Chen Geng finished speaking, Feng Hua had already shouted, as the chief engineer of the XJ750 engine, he knew too well where the potential of this engine was: "50 horsepower?!" To reach 50 hp, the engine revs at least 7,000 rpm, and the XJ750 is designed with redundancy and accuracy at all......"

"You're right, if it's the current XJ750, it's impossible to increase it to 50 horsepower," Chen Geng nodded: "However, the focus of our improvement is to use higher strength forged alloys, use high-precision CNC machine tools to manufacture crankshafts and gas distribution systems, use a coating process inside the cylinder to reduce the coefficient of friction, and other parts will be strengthened accordingly as needed; As for heat dissipation......"

After a pause, Chen Geng continued: "We have considered two directions for heat dissipation, namely the heat dissipation of the engine cylinder and the internal heat dissipation, and the engine heat dissipation is solved by two methods, one is to increase the surface area of the heat dissipation fins on the surface of the cylinder to increase the heat dissipation efficiency, and the other is to use the cylinder head water cooling, the two methods are two-pronged, and the problem of cylinder overheating under the high-speed operation of the engine is solved;

As for the heat dissipation problem of internal parts of the engine under high-speed operation, there is also a solution, one is to abandon the mineral oil used now, and replace it with semi-synthetic or even fully synthetic engine oil with better fluidity and high temperature resistance, and the other is to add an external oil radiator......"

Feng Hua's face was red and white: Yes, the engine can be liquid cooled, and the engine oil can be better semi-synthetic or even fully synthetic, but it's really not a big deal to install an external oil radiator to solve the problem of heat dissipation, and the rest is the accuracy and material strength of the parts, as long as these two problems are solved, will there be any difficulties in increasing the engine speed? Not to mention going up to 7,000 rpm, even if it goes up to 8,000 rpm, 9,000 rpm or even 10,000 rpm? I am the chief engineer of the XJ750 engine, how can I forget such a simple truth?

As the chief engineer, Feng Hua is still like this, Huo Dongfang and Wang Damin simply don't know what to say: although they haven't seen the actual improvement plan of Runhua Industry, but just listening to Chen Geng say this, the two can also think of how much energy Runhua Industry has put into the XJ750 engine.

The atmosphere fell silent abruptly.

Although Xiangjiang Machinery Factory is the manufacturer of XJ750, but for Runhua Industry to imitate and improve the XJ750 engine, neither Feng Hua nor Huo Dongfang did not feel that there was anything wrong, the national conditions of this era are like this, we have no concept of intellectual property rights at all, as long as your unit can produce then you will produce it.

Of course, there are some unpleasant ones, but the point that really makes the three of them frustrated and depressed is that as a manufacturer with a production history of twenty or thirty years, they are not as good as a unit that has never heard of the name of XJ750 before, which is really embarrassing.

After a while, Feng Hua spoke, but his voice was dry: "Since you have ...... Why ......?"

Chen Geng said sincerely: "We have indeed done some work, but after all, Xiangjiang Machinery Factory has many years of production history, rich experience, and a team of skilled workers. ”

That's true!

Although they still can't accept it in their hearts, Huo Dongfang, Wang Damin and Feng Hua have to agree with Chen Geng's words, they have not experienced the ups and downs of the market economy, and they can't see the insidiousness behind Chen Geng's seemingly win-win approach with Xiangjiang Machinery Factory...... This...... How embarrassing? ”

"What's so embarrassing about this," Chen Geng once again turned the topic back to the family minicar project of Xiangjiang Machinery Factory: "Director Huo, what is the annual production capacity of this family minicar in our previous plan?" ”

Huo Dongfang puffed out his chest and said proudly: "5,000 cars." ”

Based on the ex-factory price of each Xiangjiang brand mini-car of 3,600 yuan, the annual sales of 5,000 cars is 18 million, and then counting other industries of Xiangjiang Machinery Factory, the annual output value of the enterprise is more than 20 million, and entering 20 million means entering the threshold of state-owned super-large enterprises.

But Chen Geng couldn't accept this number, he frowned and said, "5,000? So little? ”

"5,000 is less?" Chen Geng's contemptuous expression made everyone a little unacceptable: "The production capacity of 5,000 vehicles a year, the output value of a year is 18 million, which is still less?" ”

"Less!" Chen Geng said without hesitation: "The annual output value of our Runhua Industry to transform 212 jeeps a year is similar to this, if it can't reach an annual output value of 100 million, is it worth our investment?" ”

"How much? 100 million?! ”

Huo Dongfang, Wang Damin and Feng Hua were frightened by what Chen Geng said: Do you know what 100 million means?

"Is 100 million a lot?" In Chen Geng's view, the annual output value of 100 million is only about 20,000 vehicles per year, and he really doesn't think 20,000 is a big number for this kind of mini-car as big as shoes...... Even if we can't buy it domestically, we can export it to foreigners!

But Huo Dongfang, Wang Damin and Feng Hua don't see it that way: at least 20,000 cars a year, so many cars, how can we sell them?!

To be honest, the three of them were frightened by the big cake painted by Chen Geng, and they actually felt a little retreat in their hearts.

Chen Geng sincerely hopes to cooperate with Xiangjiang Machinery Factory, and with a stable engine supply base, Runhua Industry can see all its energy invested in technology research and development and vehicle production. After thinking about it, Chen Geng said: "Why don't you go to our unit to inspect it first, and then make a decision?" (To be continued.) )
