Facing Lao Wang and Li Dacheng who were excitedly swearing to him, Zhang waved his hands: "No need! Lao Wang and the old factory manager, this is normal cooperation between us. There is no need for you to do this. Don't be fooled by simple questions." It's complicated."

Hearing what Zhang said, Lao Wang and Li Dacheng couldn't help talking, a little embarrassed, indeed, after thinking about it carefully, they also felt that they seemed to have used too much force just now.

It was Zhang, who immediately turned his head to look at Lao Wang and said, "Old Wang, speaking of it, I really have something I would like to ask for your help."

Hearing Zhang's words, Lao Wang was shocked immediately, and quickly said: "Mr. Zhang, please don't say that. Speaking of which, Huateng Group is still a shareholder of our Yadi Battery. This is what it should be."

Huateng Industrial Group needs the help of Yadi Battery for something. In Lao Wang's opinion, this is actually a very good thing. Only cooperation that is beneficial to both parties can last for a long time. Lao Wang understands this very well.

Lao Wang understands this truth, and Li Dacheng naturally understands this truth, so seeing that there seems to be nothing wrong with him, he suddenly became anxious, and quickly said: "Mr. Zhang, what can we do at Jiangbei Machinery Factory? Just open your mouth, as long as you say a word and we say no, it's my little mother's child."

"Director Li, your words are serious," Zhang smiled and waved his hands: "But I am very grateful for your kindness, but in this matter, you really can't help much."

Li Dacheng was a little unconvinced when he heard this.

On the other hand, Zhang, seeing Li Dacheng's appearance, smiled and said: "Director Li, you still don't know what happened to our group this time, so you need Lao Wang's help."

Li Dacheng was stunned when he heard the words: Yes!I actually forgot about this, what happened to Huateng Industrial Group, and then I thought of asking Lao Wang to help.

Lao Wang was actually curious at the moment: What kind of trouble did Huateng Industrial Group encounter in this regard?
Thinking of this, Lao Wang suddenly felt a little guilty: Speaking of which, with the size of Huateng Industrial Group, they are not easy to solve the problem. Can we really help with the small body of Yadi Battery?
"Let me just say it directly." Seeing the reactions of the two, Zhang didn't want to go around in circles, and said directly: "Do you know that Stealing Oil Otter has a car called Prius?"

"Stealing Prius oil otter?" Li Dacheng heard the words, thought for a while, and couldn't help looking at Lao Wang with a confused face: "I haven't heard of it, Lao Wang, have you heard of it?"

It's no wonder that Li Dacheng has such a blank expression, in fact, he really has never heard of the Stealing Oil Otter Prius.

On the contrary, Lao Wang, after hearing Zhang mentioned the Stealing Oil Otter Prius, nodded and said: "I know this car, this car is the first in the world today, and it is also the only successful car in the world so far. It is a commercial hybrid vehicle driven by gasoline and electric motors. It is said that the fuel consumption of this vehicle is very well controlled. The fuel consumption can be achieved when the power level is comparable to that of ordinary 2.5-liter to 3.0-displacement gasoline vehicles. It takes more than 4 for [-] kilometers, which is very powerful.”

Li Dacheng's eyes were straightened, he stared wide, and asked Lao Wang in disbelief: "Old Wang, are you kidding me? A car with a power level comparable to a gasoline car with 2.5 or 3.0 displacement , but the fuel consumption per [-] kilometers is only more than four liters?"...

It’s no wonder that Li Dacheng’s reaction was so intense. It’s because the comparison between the power level and fuel consumption of this car is beyond the world’s common understanding of cars. In everyone’s consensus, if a car wants good power , then it must burn more oil. For example, luxury cars from Europe, the United States and Japan, such as imported oil-stealing crowns and Mercedes-Benz, are so powerful that they can be said to fly on fuel, but the fuel consumption corresponds to the surging power: Even if you drive sparingly, the fuel consumption per 2 kilometers will be more than ten. If you step on it harder, the fuel consumption per [-] kilometers will easily exceed [-];

On the other hand, if a car is fuel-efficient, then the power level is definitely not very good. For example, the small Alto that Li Dacheng is most familiar with only needs three or four fuel consumption per [-] kilometers, but the power level... I can’t say it in a word, I can only say it’s good or bad It is also a high-speed car.

"It's true," Lao Wang nodded, and said seriously: "Toyota has applied a lot of new technologies to this Prius. For example, the engine of this car uses a 1.5-liter engine, although the power Only 58 horsepower..."

"Old Wang, wait a moment," Li Dacheng interrupted Lao Wang, and said with a surprised face: "You said that the Stealing Oil Otter Prius is equipped with a 1.5-liter engine with a power of only 58 horsepower?"

At this moment, Li Dacheng even suspected that he had heard it wrong: How could an engine with a maximum power of only 58 horsepower be related to surging power?
A simple conversion will show that the power per liter of this engine is only more than 20 kilowatts, while the power per liter of the 4g63 engine produced by Fengtian Aerospace Mitsubishi is already almost 40 kilowatts per liter. It is said that the power per liter of the engine produced by Huateng Industrial Group is even Has reached 51 kilowatts per liter, what does this mean?
This shows that the engine on the Stealing Oil Otter Prius is a solid engine whose technology is so backward that it can only be thrown into the garbage dump. How did Lao Wang describe this backward engine as technologically advanced?

Faced with Li Dacheng's reaction, Lao Wang was not in a hurry, but said: "Listen to me, the power of the engine on the Stealing Oil Otter Prius is not high, it can even be said to be pitifully low, but this The really powerful thing about this engine is that it does not use the Otto cycle we are familiar with, but the Atkinson cycle."

Poor, Lao Wang's words touched Li Dacheng's blind spot again, and the poor old Wang looked confused at the moment: What is the Alto cycle?Oh, I know the Otto cycle, is it the working method of our ordinary four-stroke gasoline engine, intake-compression-combustion-exhaust, this is the most typical way of combustion and work of a four-stroke internal combustion engine, all piston internal combustion engines in the world do not Do they all work this way?Is this Atkinson cycle any different?This kind of cycle can't escape this basic principle, can it?
He wanted to ask, but Old Wang felt a little embarrassed, and didn't know how to speak for a while.

Don't think that Lao Wang's reaction is not in line with the accumulation of knowledge that the head of an automobile factory should have, let alone think that Lao Wang, as the director of Jiangbei Machinery Factory, doesn't even know what an Atkinson cycle is. You don’t know anything about the Atkinson cycle, why are you the director of a car factory?”, Lao Wang’s reaction is actually very normal among state-owned enterprises, after all, what he needs to be responsible for is to run the enterprise well... Well, let's not talk about it, otherwise this chapter is prone to problems. …

Seeing Li Dacheng's confused face, Zhang smiled and said to Old Wang: "Old Wang, Factory Manager Li was not born in technology, and what you said is too professional, he may not understand it."

Speaking of this, Zhang turned his head and said to Li Dacheng: "Director Li, let me tell you this, the Atkinson cycle is also one of the working principles of the internal combustion engine, but compared with the more familiar Alto cycle, this The power cycle method is relatively unpopular, and its characteristics or shortcomings are also very obvious. The most notable feature is that the power of the engine is not very good at low and high speeds, especially in the low speed range, the power is very weak, but Once it reaches the middle speed period, the engine suddenly sprang up. Not only the power performance is very good, but the most important thing is that the working efficiency of the engine is also very high.

Take the 1nz-fex Atkinson cycle engine on the Stealing Prius as an example. It is said that the thermal efficiency of this engine exceeds 33%, and it can reach a thermal efficiency of more than 30% in a very wide speed range. , which cannot be achieved by conventional internal combustion engines using the Otto cycle.

As for why the Stealing Oil Otter installed such an engine that is good at mid-speed for the Prius, it is because in essence, the Prius can be said to have no gearbox. "

"What?" Li Dacheng looked surprised: "This car doesn't have a gearbox?"

If it weren't for the words coming from Zhang Zhikou, and Lao Wang was nodding at the side, Li Dacheng definitely thought that this was someone joking with him, and it was a very bad joke that mocked his IQ: how could a car not have gearbox?

But since this was said by Zhang and approved by Lao Wang, Li Dacheng had to consider the credibility of Zhang's words-the Prius stealing oil does not have a gearbox, this may be true of?

Looking at the surprised Li Dacheng, Zhang continued to explain: "Of course, I said 'it can be said that there is no gearbox', but in fact this car has a gearbox, but the basic working principle of this gearbox And the structure is completely different from the principle of traditional manual or automatic transmissions we are familiar with: the core structure of this transmission is two high-power motors and a planetary gear system..."

The core structure of the gearbox of the Stealing Oil Otter Prius is actually two high-power motors?

Li Dacheng was more and more surprised, but in addition to being surprised, Li Dacheng understood why Zhang just said that this car "can be said to have no gearbox": because he has never heard of any gearbox in the world that is based on a motor of.

Hearing this, Li Dacheng couldn't help pricking up his ears, and listened to Zhang's continuation.

"One of these two motors is responsible for generating electricity and adjusting the engine speed, while the other is responsible for driving the vehicle. The maximum power of the motor driving the vehicle is 29 kilowatts, and the maximum torque is as high as 305 Nm. , very powerful!

The most powerful thing about the Stealing Oil Otter Prius is that this car can be driven by the engine to generate electricity, and the electric motor can drive the vehicle alone, or the engine and the electric motor can work together to drive the vehicle forward. …

Because the electric motor can achieve the maximum torque output at zero speed, so at the start and low-speed and medium-speed situations, the power performance of the Stealing Prius is very good, as mentioned earlier, this car The power level of the car is almost comparable to those of 2.5 or even 3.0 displacement cars.

But after all, where the maximum power of the motor and engine is placed, the maximum output power of the vehicle is limited, so when the car needs to run faster, the real power level of the car will be revealed, especially at high speeds, you can’t It is said that this car only roars but does not go away. Anyway, it is very difficult to overtake a car. If you want to speed up on the expressway, you can basically rely on slowly going up.

But having said that, because of the existence of the electric motor and the large-capacity battery, the engine does not always need to be started, and as long as it is started, it can run in the high-efficiency range of the engine, so this car is indeed very fuel-efficient. According to foreign media reports, the daily If it is used, the fuel consumption can basically be controlled at about 4.5 per 4 kilometers. Some people say that the fuel consumption can be controlled to less than 3, and the fuel consumption per [-] kilometers only needs more than [-]. It is indeed very powerful and very fuel-efficient. "

"So this car is like this, I understand a little bit," Li Dacheng roughly understood, he nodded and said: "So Mr. Zhang, the reason why you asked Lao Wang for help is related to the electronic and electrical system on this car?"

"That's right," Zhang Ying said, "This car is equipped with a set of nickel-chromium battery packs..."

Hearing this, Pharaoh immediately understood: Pharaoh's Yadi battery is the world's largest manufacturer of nickel-chromium batteries. If Huateng Industrial Group needs nickel-chromium batteries, it really needs Pharaoh's help, and his own Side also really can't help.

As for Zhang, after talking about this, Zhang looked at Lao Wang and said: "Old Wang, I won't hide it from you, our Huateng Industrial Group is very interested in stealing hybrid cars like the Oil Otter Prius, but I think the nickel-chromium battery is a bit We are lagging behind, I hope that Yadi will work with us to jointly develop a power-type nickel-metal hydride battery and a corresponding control system that can be used for deep charging and deep discharging, and is suitable for automobiles, how about it, are you interested?"

"Of course no problem," Pharaoh said without hesitation, "We'll talk about the specific details of the cooperation later, but Mr. Zhang, as far as I know, it seems that the ths gearbox on the Stealing Oil Otter Prius has applied for strict approval. As for international patents, how do you plan to solve the...patent issue?"

"I understand what you mean, don't worry, I will not infringe on the ths patent of the oil otter," Zhang said with a smile: "After all, the technical route of hybrid cars is not only the ths of the oil otter."

When Old Wang heard this, his eyes widened in shock!
Before that, he always thought that Zhang was going to "copy" the ths patent of the oil otter. **Maybe using his public power to force the oil-stealing otter to acquiesce, but what he didn't expect was that he Zhang actually thought of the second ths hybrid technology route besides the oil-stealing otter ths?
Lao Wang was really frightened.
