Deputy Director Yang was frightened by what Chen Geng accidentally shot out: You are the boss of a company, it would be fine if you know design, but how could you be so proficient in the characteristics of materials and technology? You are like you, will you still live?

Compared with Chen Geng, he actually felt a little inferior: everyone is human, they carry one head with two shoulders, and no one compares to one more head with one leg. Why are you so much better than me?

Chen Geng did not notice the corners of Deputy Director Yang's mouth twitching slightly, and whispered: "It's not a technical problem, it's another problem."

It's not a technical problem, Deputy Director Yang nodded: "You said."

"About this backup power system, there are now two sets of solutions, each set of solutions divided into two small solutions. The first is 'battery pack + motor'. In this major category, the two subdivisions are to choose single motor or front and rear motors; the second is the scheme of 'generator set driven by internal combustion engine + battery pack + motor with adjustment capabilities'. The following two subdivisions are the same as those in the previous category, and are also divided into single motor and dual motors..."

"You need dual motors!" As soon as Chen Geng finished speaking, Deputy Director Yang said without hesitation: "As long as you can achieve technically and meet the requirements in terms of reliability, you must have dual motors."

The fool only needs a single motor solution. Chen Geng just said that the front and rear dual motor solutions can not only work at the same time to enable the car to achieve electric four-wheel drive, but also be backups for each other. Any motor fails or is damaged, and the other motor can also drive the car away. With this powerful redundancy and survivability, only the fool can choose a single motor as long as it can be technically implemented.

Deputy Director Yang frowned slightly: "What are the advantages and disadvantages of the two plans you mentioned...?"

Chen Geng: "The first solution is to ensure that the car can drive 30 to 50 kilometers in a pure electric state, the energy of the entire vehicle's battery pack must reach at least 20 kilowatt-hours. At the current battery level, the weight of these battery packs is about one ton. With the weight of two motors, control systems and cables, I estimate that the weight of the entire electric drive system will reach 2 tons, which is a big problem for the load of the car, and how to arrange the 20 kilowatt-hour battery pack under limited space is also a big problem."

Deputy Director Yang frowned: The weight of a system must reach two tons? Chen Geng said rightly, this is indeed a big burden for a car, and the space occupied by a 20-kilowatt-hour battery pack and its own weight are all very problematic. This thing is not a truck, and can be placed at will. As a key guardian vehicle that needs priority to ensure safety and crew space, there is really not much space available.

"What about the second type?" Deputy Director Yang asked: "What are the advantages and disadvantages of the second type?"

Chen Geng: "For the second plan, I plan to use the engine on a supercar we jointly developed with Yamaha as the prime mover for the generator set..."

"Wait for a while," Deputy Director Yang was stunned and asked hurriedly: "The Yamaha you lost, is it the Yamaha that makes motorcycles?"

"It's that Yamaha." Chen Geng nodded.

"Comrade Chen Geng, what are you doing?" Deputy Director Yang frowned again as he stretched his brows. He was a little unhappy: "What is a supercar? Ferrari, Lamborghini, this is a supercar. You and a motorcycle company jointly develop supercars? Isn't this a joke?!"

"Old Yang, you're very wrong," As soon as Deputy Director Yang finished speaking, someone next to him immediately teased: "You know that Yamaha is a motorcycle, do you know that Yamaha can also make pianos and musical instruments?"

"Maybe our Comrade Chen is interested in Yamaha's level of musical instruments?" Someone next to him didn't pick up any pot, and he didn't know what he was thinking.

"..." Deputy Director Yang didn't say anything and glared at Chen Geng fiercely: It would be fine if you ask others to cooperate, but you would find a company that makes musical instruments and motorcycles to cooperate in developing super sports cars? Are you thinking about it?

Comrade Chen Geng said that he was innocent: Who am I provoking whom?

"A bunch of illiterate people, don't talk nonsense if you don't understand!"

Li Xueshan finally couldn't help it. Chen Geng, a little bastard, didn't marry Lin Shuyao. Of course, Li Xueshan was very annoyed. He never gave him a good look since he met. But Li Xueshan could not give Chen Geng a good look, which did not mean that others were qualified to point at Chen Geng's nose and scold him. If I could scold him, you can't!

Looking at the major general and lieutenant generals in front of him with contempt, Li Xueshan had the urge to raise his middle finger at the guys in front of him: "What are you blind people who don't know anything? Do you know that Yamaha is not only the world's top motorcycle manufacturer, a high-level musical instrument manufacturer, but also an engine supplier for the F1 race? Do you really think that they can only build motorcycles?"

What?!

Yamaha’s motorcycles are very famous in the world, and everyone knows this, but not only are they very powerful in making motorcycles, they are also engine suppliers for F1 races?

Damn it is true or false?

The first reaction of a group of generals was to not believe it.

What is F1? This is the world's top automotive event, representing the world's top automotive technology and concepts. Which one is not a long-standing old company? Only top performance cars such as Ferrari, Cosworth, McLaren, and BMW are qualified to be the F1 engine supplier. When is the Japanese turn to show off in the F1 field?

"Lao Li, what are you kidding?"

"A motorcycle factory that makes pianos or an F1 engine supplier? Haha... This is the most proud joke I have heard this year..."

"I'm just pointing at this joke to make fun of it..."

…………

Li Xueshan didn't say anything, but just looked at the guys who didn't know anything and dared to draw conclusions without proof. His contemptuous eyes clearly revealed a meaning: You group of scumbags who don't know anything!

Slag?!

Who do you think is the slag?

A group of generals suddenly became angry. Everyone is a general. Why are you so awesome? Even if you, Li Xueshan, have one more golden bean on your shoulder (two) than me, you must explain it to me!

Faced with the surging feelings of the generals, Li Xueshan pushed Chen Geng forward: "If you have any questions, just ask this kid, and he knows what you want to ask."

He looks like "I actually know everything, but I just tell you disdainfully."

A group of generals were furious: I have seen people pretending to be x, but I have never seen people who can pretend to be x like this.

But there is no way. Who makes you have more golden beans on your shoulders than yourself? You can't use a strong one? Are you still looking for the upper and lower levels? Fortunately, there is someone in front of you who looks easier to bully...

Facing the malicious eyes of a group of lieutenant generals, what can Chen Geng do? He is also very desperate.

"Although Yamaha does not have experience in vehicle manufacturing, it is still very powerful," under the gaze of a group of lieutenant generals, Comrade Chen Geng, a small "two-quarter" who said weakly: "They are not only two engine providers with Honda that have experience in the F1 engine manufacturing process, but also have cooperative relationships with many automobile manufacturers in the world. Ford, Toyota and Honda's many active main engines were jointly developed with Yamaha.

Oh, by the way, Yamaha has developed a super sports car, OX99-11, based on their F1 racing engine. This super sports car has a speed of more than 360 km/h, and 0 to 96 km/h acceleration takes 3.2 seconds. It is a very powerful super sports car. In terms of performance alone, the performance of any super sports car sold by Ferrari and Lamborghini is not as good as this car, because this car directly uses a 3.5-liter V-type 12-cylinder engine for the F1 racing event, but it has made some optimizations in terms of reliability. The maximum power of the engine can reach 660 horsepower."

A 3.5-liter engine with a maximum power of 660 horsepower...

Today's generals are somewhat versatile. Even if they don't understand technology, they are very clear about what this data means: I heard that the 2.2-liter engine used in the Audi 100 sedan that FAW is producing has a maximum power of only 87 horsepower...

Deputy Director Yang was ecstatic!

Chen Geng’s meaning is that he is planning to move this 660-horsepower engine to this Phoenix bulletproof car as the prime mover for the generator set?

Damn it!

If there is such an engine to generate electricity, why can it be enough for two motors?

Although he didn't know how much the weight of this engine was, he knew one thing, that is, any engine in a professional car event would be lightweight, it must be lightweight, lightweight and lightweight. In this way, the weight of a generator set plus a battery pack should be lighter than the weight of a 20-kilowatt-hour battery pack.

Although I was already inclined to the second option, Deputy Director Yang made a decision on the safe side: "Comrade Chen Geng, in this way, you can make both systems and we will evaluate them together. We will use which one is better."

"No problem," Chen Geng agreed without saying a word, not even bargaining, but this does not mean that Chen Geng agreed so stupidly: "But the purchase application of Phoenix sedans from the Ministry of Foreign Affairs..."

I know it's not that easy.

Deputy Director Yang did not find any surprise to Chen Geng’s request. On the contrary, he felt that it was normal. Runhua Industrial took out so many things and so many real benefits. It was reasonable and he helped him.

"This is easy to say," Deputy Director Yang nodded happily, and said meaningfully: "In addition, you don't have any pressure on FAW. As long as you do your own thing well, there will be no other problems."
