Chapter 1397 Giants with a keen sense of smell

"Yes," Tian Tian nodded affirmatively. "The method is actually quite simple and crude. Just pile up motors, and pile up big motors! If one motor is not enough, then use two! If a 70-kilowatt motor is not enough, then use a 110-kilowatt motor. If that still doesn't work, then adjust the reduction ratio to a larger level, sacrificing the maximum speed in exchange for the acceleration capability in the front section."

Mr. Feng looked at Liu Ming: Will this work?

However, Liu Ming seemed to be thinking about something. After a moment, he slowly said, "Isn't this too crude?"

As the chief designer of the new generation of Excelle, Liu Ming certainly participated in the calibration work of the hybrid Excelle. He was no stranger to hybrid power and the characteristics of electric motors. As soon as Tian Tian's words came out, he knew that this was indeed a solution. However, the knowledge accumulated in the automotive field over the years made Liu Ming feel that doing so was simply too simple and crude, and too unskilled. To achieve such 0-100KM/H acceleration, shouldn't one rack one's brains to work hard on the engine, gearbox, and chassis? How can one just "bang bang" two motors and call it a day?

Tian Tian asked back: "You mean if we do this and add two 110-kilowatt motors, can we make the Excelle's 0-100km/h acceleration reach the 4-second level?"

"This……"

Liu Ming was speechless, and finally said: "I can't say whether it can reach more than 4 seconds, but more than 5 seconds should be no problem. It's just that doing this will eventually... eventually..."

What he wanted to say was that this idea was feasible, but compared with the traditional approach of trying to develop V8, V10 or even V12, it was ultimately heresy and a wrong path. But when he thought about the fact that the "hybrid electric vehicle" technology route was a new energy technology route recognized by the world today, he didn't know what to say for a moment.

Tian Tian, ​​who was born in the field of hybrid conversion engines, although she was working with internal combustion engines, had been dealing with motors, electronic controls, and batteries for no less time than she had with internal combustion engines. Although Liu Ming's words were vague, how could Tian Tian not hear what he was thinking? He said seriously: "Mr. Liu, I understand what you mean, but I think that 0-100 acceleration is, after all, just a game of 'power and speed'.

The mainstream approach of European and American manufacturers is to stack cylinders. If there is no space for stacking cylinders in the engine compartment, they will use turbocharging. I don’t think our approach of stacking motors is fundamentally different from theirs. Isn’t the ultimate goal to increase the power on the wheels? "

Tian Tian’s words really left Liu Ming speechless.

But Mr. Feng really understood it at this moment: the method of stacking motors is feasible!

  The old man suddenly became excited: Since it is feasible, then it’s easy to talk about it!

With the same power, how big is the engine and gearbox? But how big is the volume of the motor plus a single-stage gearbox?

He nodded with a smile: "Since the technical route is feasible, let's do it. Mr. Zhang will be back soon. When he comes back, you should give him a preliminary feasible plan."

....................................

Seeing Zhang Qihang again, Mr. Feng was extremely happy. After a few pleasantries, he asked Zhang Qihang impatiently, "Come on, Qihang, tell me why we all thought it was unlikely to use official channels to force the promotion of the mild hybrid system, but why did the higher-ups finally decide to do so?"

  Although we had communicated on the phone before, how could it be as comfortable to talk on the phone as to chat face to face?

Zhang Qihang smiled and said, "It's a coincidence..."

After Zhang Qihang finished speaking, the old man nodded repeatedly: "No wonder, if this is the result, it's no wonder that the leaders are tempted. During the evening rush hour, the fuel saving rate is almost 50%. How can this be possible? But such a big piece of fat meat, it is impossible for our family to eat it all, right?"

"That's not possible," Zhang Qihang shook his head. "International auto parts giants such as Bosch, Delphi, and Siemens also have their own mild hybrid systems. Even if they don't have them, they can integrate the existing technologies and come up with something that looks like it. After all, this is not a great technology.

The leaders’ meaning is very clear. They only require that all passenger cars must be equipped with mild hybrid systems when the National IV emission stage comes. However, it depends on who the mild hybrid system is. Everyone will compete in the market based on their own ability. ” At this point, Zhang Qihang was happy: “As long as no one takes sides, who are we afraid of?”

"Haha... that's right," Mr. Feng was also amused when he heard this. He nodded repeatedly and said, "That's the truth... other domestic manufacturers, even those joint venture brands, as long as they are not stupid, will also purchase a certain amount from us."

Zhang Qihang heard it and started laughing too.

In the past one or two years, all major domestic automobile brands have purchased some of the products of Huateng Auto Parts, a subsidiary of Huateng Group, from Huateng Auto Parts. Not only relatively basic products such as ABS+EBD, but also high-end automobile accessories such as ECU computers and ESC systems.

Not only domestic brands, but also joint venture brands do this.

Everyone has learned their lesson and uses this method to bargain with old auto parts giants such as Delphi and Bosch: If you don’t bargain with me, then I will increase my purchasing share for Huateng Auto Parts.

Bosch, Delphi and Siemens were so angry that they gnashed their teeth, but there was nothing they could do but slowly lower their prices, because the auto parts they could provide could also be provided by Huateng Auto Parts.

"Oh, by the way, there's something I forgot to tell you," Mr. Feng slapped his forehead when he said this, "Yesterday, Rudolf Braumen, the general manager of Bosch (Huaxia), called me and said he wanted to visit you."

Zhang Qihang reacted instantly: "Are you here for the mild hybrid system?"

"He didn't say, but I guess that's what happened."

"Then they are well-informed."

Zhang Qihang said this, but there was no strange expression on his face - if industry giants like Bosch, Siemens and Delphi did not have some direct information channels to the sky, how could they grow their business so big?

You know, when the head of Germany comes to visit China, the president of Bosch can accompany him on a special plane. This shows what level and weight of a company Bosch is.

"Normal," Mr. Feng asked leisurely, "What do you mean?"

"Just counter it as it happens," Zhang Qihang said with a smile, "We've been friends for so many years, right?"

"Hahaha……"

Mr. Feng was immediately delighted and nodded to Zhang Qihang twice.
