"Electric transmission? Mr. Hu, you are kidding, how can the efficiency and volume of electric transmission equipment pose a threat to mechanical transmission? Even if we have the latest GTO technology developed in Germany, don't want to challenge the status of mechanical transmission! If you are not a professional, it is better not to talk nonsense. ”

Stuart was confident and did not care about Hu Wenhai's threat.

"Oh, that's just to say that you German engineers are not very good, but that doesn't mean that other countries can't do this kind of process. ”

Hu Wenhai gave Fu Zhiheng, who was sitting next to Stuart, an inquiring look, and after seeing him nod, he took a deep breath and said, "Chief Engineer Fu, who came with Mr. Stuart, I think you should know his position in China. Chief engineer of the Chinese railway department, he was commissioned to develop a new diesel locomotive with 8,000 horsepower. ”

Stuart raised an eyebrow, noncommittal. However, judging from his gaze, it was obvious that he was not very optimistic about dealing with Zhiheng's task.

Hu Wenhai chuckled, not caring about Stuart's attitude, and continued: "Maybe Mr. Stuart doesn't know that this new diesel locomotive is planning to use electric transmission technology. To tell the truth, China has made a major breakthrough in chopper rectification technology and developed a medium-voltage variable frequency power semiconductor control switch. Well, it's a bit of a mouthful, if you like, you can call it the abbreviation IGCT technology. ”

"IGCT?power semiconductor control zhì switch?" Stuart looked confused.

Hu Wenhai patted his head, okay, forget that this is actually the vice president of an engine company. Even if it is assumed that he is a technician, it is estimated that he also studied mechanical technology, which is almost separated from the power semiconductor by the Clark Isthmus.

Hu Wenhai no longer thought about how Stuart could understand the meaning of IGCT, but casually found a piece of paper and pen from the coffee table, and wrote down a set of numbers.

"Mr. Stuart can send this set of numbers back to Germany and let your power engineers see what it means. Please rest assured that I can get a guarantee from the Chinese government for the authenticity of this number. Chief Engineer Fu, will you tell Mr. Stuart?"

At the end, Hu Wenhai turned his head to look at Fu Zhiheng and asked frankly.

Fu Zhiheng nodded, cleared his throat and said directly: "Mr. Stuart, although Mr. Hu's identity is a businessman, as the chief engineer of the Ministry of Railways, the administrative level is at the level of deputy minister, and my identity can fully make commitments on behalf of the Chinese government - this set of numbers about IGCT technology is completely true and correct, and has been recognized by the National Academy of Sciences, an authoritative institution in our country. ”

As he spoke, Fu Zhiheng took the pen from Hu Wenhai's hand and wrote a letter of guarantee on the paper. He proved the authenticity of IGCT technology with his political credibility at the vice-ministerial level.

Hu Wenhai's choice to expose IGCT technology at this time is obviously considered mature.

First of all, the most important point is that the equipment of the new technology wafer fab has been loaded on the ship, and it is about to arrive at the Modu wharf. The new technology fab project has already begun, and unless more than half of the leaders of the Presbyterian Church are hypnotized, the project is already unstoppable.

In other words, by this time, there is no force that can stop the construction of the new technology wafer factory, and there is no force that can stop the rhythm of the new technology in the field of power semiconductors.

Fundamentally speaking, IGCT technology has no production technology problems, and is purely a design idea problem, which also makes it impossible to make money from products and patents alone. Before providing products to the market, if Hu Wenhai wants to maximize profits, he should license IGCT technology as much as possible. Sell one round of patented technology first, and then sell another round of low-priced products.

Now is the right time to throw out IGCT technology. It's just that Zhuangbility made a mistake, and the flattering eyes were thrown to the blind man......

However, although Stuart does not understand power technology, MTU has power engineers. In addition to mechanical power, MTU's diesel engines are also available for power generation.

Stuart, who was suspicious, took Hu Wenhai's number jù and Fu Zhiheng's certificate, and went back to find someone to verify it.

In his view, this is just a means of bargaining for the Chinese side. If the Chinese can really make any world-class results, I am afraid that a German will not believe it.

What is a standard German? weak-willed like a German bureaucracy, unscrupulous like a Protestant, incorruptible and shameless like a Prussian officer.

Ahem, the above is a joke. In the 80s, the Germans were not the country that made fun of the military led by Aunt Biller five days a week as a civil servant. On the contrary, the Federal Republic of Germany, which is facing the front line in Europe, still has some guarantee of combat effectiveness.

Of course, this was followed by the hostility of the Germans to the socialist countries. Although relations with China are not so tense, the Americans have established diplomatic relations with China, and the Germans will not hold on to it.

What's more, the Chinese market has great potential, and MTU is always going to come in. However, although this reason makes MTU willing to make efforts, the German ** sentiment is still the mainstream after all. This contradiction is also reflected here, on the one hand, MTU hopes to win this order, but on the other hand, the Germans, who look down on China, shout a high price.

It's not that the $100 million transfer fee is not negotiable, and the sky-high asking price is to pay back on the spot, which is not the rhythm of the business.

However, who let them meet Hu Wenhai, who did not play according to the rules, had no intention of counteroffering at all, but came up and shot a dull stick.

Stuart sent Hu Wenhai's number back to the German headquarters, repeating the negotiation process over the phone. Of course, as far as he understands personally, this is just a means of negotiation for the Chinese.

According to the analysis of the Germans, the Chinese demand for Type 1163 diesel engines should be very large. If this technology introduction fails, will China consider directly importing finished products? Although in this way, many important uses will definitely be replaced by domestic diesel engines, but MTU can sell more advanced high-performance diesel engines to China, and make money back from the production line through high added value.

It may take a little longer, but it's still acceptable as a planb.

MTU really wants to make this deal, after all, business is business, **is**. The capitalists have never hesitated to sell the ropes on which they hanged themselves.

Of course, the capitalists never thought that there was an opportunity to put the rope of sale around their necks.

The MTU executives who listened to Stuart's report also thought so. If the Chinese have any technology to threaten the hegemony of MTU diesel engines, it is better to convince them that American allies are constantly listening to the German Chancellor's phone calls, and the latter may be even more likely.

However, when the power engineer of MTU was summoned and looked at the number of Stuart faxes, his face immediately changed.

......

"Mr. Hu, MTU company, will it ......?"

Fu Zhiheng walked back and forth in the room, looking quite worried.

"Lao Fu, don't turn around, I'm dizzy!" Hu Wenhai put down the pen in his hand, and had to shake his head helplessly and smile bitterly: "What are you worried about? The Germans have long been monkeys in our hands, and they can't jump out of Wuzhi Mountain." ”

Fu Zhiheng looked at his watch, sat down on the sofa unwillingly, and said: "It's been almost 24 hours, why hasn't MTU replied yet?" In case the Germans really don't do this business, or are not interested in IGCT technology at all, the ministry wants to put on a new 8,000-horsepower nose plan, but it will all be in vain!"

"Lao Fu, you are the one who cares about it. It is impossible for the Germans not to be interested in the IGCT, which has increased the efficiency of the electric transmission above the efficiency of the mechanical transmission, how is this a big deal?

"It's hard to say, historically, the promotion of technology is not just a matter of comparing efficiency and performance. For example, the dispute between GM and Westinghouse, AC and DC, this is not a simple theoretical problem. ”

Fu Zhiheng looked a little breathless, and sighed: "Even if the Germans believe in the IGCT number index, it is not necessarily on our side, and it is possible that the IGCT technology will be suppressed simply, or even very likely." After all, mechanical transmission and electric transmission, the choice of engine performance is completely different. If IGCT technology is widely used, many of MTU's technical advantages in diesel engines will become a pile of waste paper!"

No wonder Fu Zhiheng is so worried, the impact of electric transmission on the development of diesel engine technology route is very large. Mechanical transmission engines, such as torque, response speed, transmission structure, power peak, these parameters are very important to the performance of an engine. Insufficient torque, poor climbing, unstable engine power output. The response speed is slow, and it takes half a day to feel the speed increase when you step on the throttle, and the requirements for people are high when you operate. The transmission structure is unstable, the power and operation are difficult, and it will affect the operation feeling. What is the maximum amount of power that the engine can provide? It is very difficult to increase this value......

Specifications like these are very important performance options for the engine. However, when it comes to electric transmission, it is different.

The motor has a theoretically infinite torque when it is fed electricity, and the response speed is a second-kill mechanical transmission, and the transmission structure is equal to no reliability higher than the mechanical transmission, and the peak speed is basically meaningless. As long as the traditional generator is equipped with a set of supercapacitors, it is simply easy to increase the instantaneous peak value.

So in the end, if you want to run on the electric drive, the important technical indicators of the engine have become another technical route such as trouble-free time, fuel consumption, and power conversion rate.

MTU has a high market position and technical reserves in the field of traditional mechanical transmission, if you want to switch to the electric transmission route, I don't know how much money will be wasted.

Looking at it this way, it is really difficult to say whether MTU will definitely accept this idea of electric transmission.

Hu Wenhai smiled and said indifferently: "Lao Fu, what are you worried about? Without Zhang Butcher, who must have to eat hairy pigs?"

"This, MTU company is the best technology in the diesel engine market, and the products of other companies may not be able to meet the needs of the department. ”

"Who said you don't want MTU technology?" Hu Wenhai blinked and smiled mysteriously: "Even if MTU really wants to boycott IGCT, I can still guarantee that the Ministry of Railways will get the technology of 1163." ”

Fu Zhiheng looked uncertain, shook his head and said: "If MTU doesn't provide technology, even if we want to imitate, we may not be able to succeed." ”

"Who said it was going to be imitated?" Hu Wenhai was confident: "Let's give MTU a face, and only then do we plan to get the original technology from the main owner." But don't forget, Canada has already introduced the production technology of 1163 in the 70s, and we can completely import it from Canada again. ”

"Canada's technology licensing, can it be re-licensable?" Fu Zhiheng cheered up, if this is the case, there is really no need to hang himself on the tree of the MTU family.

However, Hu Wenhai shrugged his shoulders and said innocently: "Who knows, in order not to startle the snake, I have never been in contact with Canada." ”

"That ......"

Hu Wenhai laughed: "What does it matter, of course it is best that Canada's 1163 can be re-authorized, and it doesn't matter if it can't." When the time comes, a sum of money will be paid to ask Canadians to help build the factory. Nominally hanging the Canadian brand, the actual operation is needless to say. The products produced are sold back to Canada and then imported into China. You don't have to go abroad, you can take it out and sell it after going around the warehouse for a while. MTU will look at it dryly, and there will be nothing wrong!"

Fu Zhiheng was dumbfounded when he heard this, and he almost couldn't close his mouth: "You can still do this!"

Hehe, Hu Wenhai smiled softly, in order to compete openly and secretly with these large enterprises that want to earn super profits in China, the Chinese have invented more methods. Decks like this are just the most basic means of circumvention.

Fu Zhiheng thought about it with excitement on his face, and confirmed that this method was indeed really feasible, and almost jumped up from the sofa.

If he hadn't been counting on in-depth cooperation with MTU in the future, he would have even thought about putting MTU aside now and working directly with the Canadians.

Fu Zhiheng on this side is confident and high-spirited, but Stuart on the other side is full of sadness and frowns.

"Is Chinese's technology really so important?"

In the 80s, there were only a few places in China that could make international calls, and Stuart borrowed a long-distance telephone from Volkswagen's office. He sat on the sofa in the telephone room, holding the telephone in his hand, and loosened his neckline tie a little anxiously, his face full of disbelief.

On the phone, Karl, the president of MTU, was silent for a moment, and said slowly: "If the number of IGCT technology can really reach the level you transmitted, it is indeed a technology that can change the world, and the impact on engine technology cannot be ignored." ”

"That's the Chinese lying. Stuart snorted.

"What about motivation?"

Karl sighed: "You have a letter of guarantee from a high-ranking Chinese official, this technology can be verified by any power engineer, and the lie is not only quick and easy to debunk, but also harmful." ”

"Maybe it's Chinese bluff to drive down the amount of the deal we sold our technology......"

"The speculations now are inaccurate. Karl interrupted Stuart: "I've asked Volkswagen for help, and they'll assign you a power engineer." Take him with you and verify that the Chinese's technology is as advanced as they say it is. ”

"Okay, Carl. Stuart thought for a moment and nodded, "I will expose the tricks of the Chinese." ”

"Stuart, a bit of professionalism, you're the vice president of the company. Karl nodded at him noncommittally, and hung up.

Stuart held the phone and thought about it for a long time, until a piercing hang-up tone came from the phone, and then he came back to his senses.

He put the phone back in its place and walked out of the phone booth to see a black man in a blue plaid shirt and jeans standing in the doorway.

"Mr. Stuart, I'm Klay Thompson, you can just call me Clay, I heard you need help?"

Stuart frowned slightly, but quickly adjusted his expression, and took the initiative to reach out with a smile: "Mr. Clay, I will trouble you more in the next work." ”

......

"Mr. Stuart, you don't have to worry too much!"

Klay Thompson appears to be at least half white, and the black is not obvious. But as soon as he opened his mouth, it soon became clear that he was indeed a real black man - because he was so noisy.

"If you want me to say Chinese what kind of technology will be developed to change the world? This is incredible! Do you know? They can't even make the electroplated reflectors on the cars, and Volkswagen has to teach Chinese how to build cars, but even if their cars are assembled with original German imported parts, the quality is still not as good as the whole vehicles imported from Germany! Such a country should first lay a good industrial foundation and workers' education, instead of pursuing any high technology, I think you must have been deceived, Mr. Stuart, you must have been deceived......

The car carrying the two of them drove into the scientific research institute of the Modu Railway Bureau, surrounded by lush green trees, and the car stopped at the door of an inconspicuous three-story building.

Fu Zhiheng personally stood in front of the door, greeted Stuart and Clay with a smile and walked towards the door, introducing the research institute of the Ministry of Railways in the magic capital as he walked.

The scientific research institute of the Modu Railway Bureau is mainly responsible for the research of the principle of control and the mathematical model of railway traffic, and relatively focuses on theoretical research, so there are not too many practical equipment, but there are a lot of computers.

Passing by one department after another, many of the people in it were tapping on old computers, and some were even fiddling with Sharp's programmable calculators. With such primitive and rudimentary scientific research conditions, Stuart couldn't help but shake his head, and it was hard to imagine what great achievements could be produced in such a research institute.

And this scientific research institute under the Ministry of Railways, which is located in the magic capital, seems to be quite advantageous in the eyes of the whole of China.

"Mr. Stuart, Mr. Clay, please come here. Fu Zhiheng smiled and pushed open a door, and then made a gesture of please.

Stuart walked towards the door without relent, and for some reason, he felt that Fu Zhiheng's smile today seemed to have more confidence in his smile inexplicably. This was completely different from the first time they met, when Fu Zhiheng had a lot of respect for him, the vice president of the MTU company—no, Fu Zhiheng still respects him and Clay a lot, but, he just felt that there was something less and more in the other party's smile than then......

When Stuart saw Hu Wenhai in the real room, the old god was fiddling with the real equipment on the table, he suddenly came to his senses.

Fu Zhiheng has become the same as Hu Wenhai when he first met, more calm and less urgent than before.

This made him feel a little uncomfortable, mtu's engine technology should be an important technology that Chinese can't wait to master! Why do they smile as if they don't care?

"Mr. Stuart, we meet again. I don't know what the number I gave you, what is the opinion of the MTU company?"

Hu Wenhai raised his head, clapped his hands and asked straight to the point.

Stuart glanced at Clay out of the corner of his eye, shook his head, and said, "MTU believes that the IGCT technical indicators you claim are not certain and need to be re-identified." ”

"Of course, I'm ready. Hu Wenhai pointed to the test bench behind him: "All the equipment here can be inspected by the MTU company, and if you still feel that it is not safe, the MTU company can even provide the real equipment and personnel you believe in for testing until you believe it." ”

Hu Wenhai's strong self-confidence made Stuart a little like a man. He nodded to Clay, who whistled and walked over to the test bed.

"Hey, I don't think it's useful for you to do this, it's useless, you know?" Clay held his head high proudly, and looked at the equipment on the test bench with disdain: "I can definitely find your handle, and no tricks can escape my eyes!"

"Oh my God, can't you be more professional with what you've prepared?" Clay fiddled around on the test bench for a while, nodding, "It's kind of like it, this should be a chopper circuit." What kind of method do you use? SCR? GTO? I heard that you don't even have SCR technology, so you don't know how to use mechanical switches, right?"

The so-called chopping wave is actually very simple to understand, and in layman's terms, it is to turn the way of the sine wave into a rectangular wave. The way to realize this function is to control the proportion of time when the current is turned on and off through the guò switch, change the voltage and current average value added to the load, and finally realize the step-up and step-down functions of the current, and provide a stable current supply.

The earliest chopper was controlled by a mechanical switch, and the switch was disconnected or switched on when the voltage reached the set position, which was the initial mechanical chopper. For example, the typical method is to use a relay to connect to the electric bell to achieve the chopping.

Later, people used a sliding rheostat to replace the mechanical switch, and the resistance was controlled to realize the opening and closing of the switch, so that the switching speed and frequency could be greatly improved.

In the end, it was found that power semiconductor devices such as variable silicon can achieve higher frequencies and speeds than rheostats, so that the electric transmission can barely achieve the efficiency of mechanical transmission.

It wasn't until the advent of GTO technology that electric transmission seemed to have the slightest possibility.

However, after Clay groped for the equipment on the test bench, he couldn't help frowning. Strange, he doesn't seem to see any kind of chopper device on the market?
