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 26P 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 been producing 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 recognized Chen Geng's statement, but he thought that this reason was not enough, as a company that can 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: "There is more"

Do you want to say it, for the second reason, Chen Geng is a little embarrassed.

However, after thinking about it again, Chen Geng still decided: even if he didn't say it, the other party would know sooner or later, since this was the case, he simply said directly: "Don't hide a few, our unit is improving and upgrading the performance of the XJ750 engine, Xiangjiang Machinery QÌ Factory has a lot of experience in XJ750 this engine, and we sincerely hope to get the technical support of Xiangjiang Machinery QÌ Factory."

"You guys are making improvements to the XJ750" Before Chen Geng finished speaking, Feng Hua asked curiously: "How did you change it, can you tell me about it?"

"Of course there is no problem," Chen Geng nodded, and the next step is to need the technical support of Xiangjiang Machinery Factory, which is not a problem: "The main thing is the optimization and beautification of the external shape of the engine, the improvement of the strength of individual performance parts, and the improvement of the level of power output."

"You intend 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 XJ750 most deeply in China, but Feng Hua regrets that although he also knows that the XJ750 engine has great potential for improvement. However, 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, but also a shame. Now that he heard Chen Geng say that they Runhua Industry is now improving the XJ750, how can he still hold back and almost can't wait: "Manager Chen, what step have you done?"

"Our goal in the first phase is to increase the maximum output of the XJ750 to 32 hp and the maximum stable speed to 4500 rpm, and the concept and technical design have been completed. Now the stability test is carried out, and if nothing else, this batch of engines will be available before the end of the year;

The second step is to increase the maximum output to 40 horsepower and the maximum speed to 5500 rpm, and now we have raised the maximum stable speed to 5200 rpm, and the optimistic estimate is that it is expected to enter the stable dìng test stage by next summer;

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

"This is impossible" 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 wants to reach 50 horsepower." The engine speed is at least 7000 rpm, and the XJ750 is not so redundant and accurate 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. One is to increase the surface area of the heat dissipation fin on the cylinder surface 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 cylinder overheating problem under the high-speed operation of the engine is solved;

As for the heat dissipation of the internal parts of the engine at high speed. One is to abandon the mineral oil currently used and switch to a semi-synthetic or even fully synthetic 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. It's really not a big deal, an external oil radiator solves 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, what difficulties will there be in increasing the engine speed, not to mention that it is increased to 7000 rpm, even if it is raised to 000 rpm, 9000 rpm or even 0000 rpm, how to lose himself is the chief engineer of the XJ750 engine, how can he 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's words, 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 QÌ 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 frustrates and frustrates the three of them 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 very dry: "Since you are already there, why bother?"

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, we are stronger than technology, and Xiangjiang Machinery Factory is stronger than production.

This is indeed the case

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. That's embarrassing."

"What's so embarrassing about this," Chen Geng once again turned the topic back to the family minicar project of Xiangjiang Machinery Qì 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 is 3,600 yuan, the annual sales of 5,000 cars is 000000 yuan, and then counting the other industries of Xiangjiang Machinery Factory, the output value of the enterprise in a year 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 is so little"

"5,000 vehicles is still less" Chen Geng's disdainful expression made everyone a little unacceptable: "The production capacity of 5,000 vehicles a year, the output value of a year is 00000, which is still less"

"Less" Chen Geng said without hesitation: "The annual output value of our Runhua Industry to transform 22 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 is 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, for this kind of mini-car with a large size of shoes, he really doesn't think that 20,000 is a big number, even if we can't buy it in China, we can also 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: "It's better to go to our unit to inspect it first, and then the three of us will make a decision."
