When Xu Fufang and Wang Rui saw the drawings of the hybrid system, their first reaction was, "Isn't this the template for the train's internal combustion engine?"

But in view of the fact that he has been seemingly inexplicable by Li Fanyu before, but he can often be slapped in the face with unexpected technology. Pen %Fun %Pavilion www.biquge.info these two goods are still patient, and I have read all the drawings.

When they saw the conversion of the electric field and the power operation part, they finally noticed something different.

The unconventional energy conversion rate is one, and what makes the two of them find this system even more strange is the power recovery system and the transmission system.

In conventional dual-engine hybrid vehicles, such as Toyota's dual-engine technology, the main mode of power recuperation is to convert the force generated by braking into electricity and rush into the battery. But in this system, this power conversion is different.

What is very puzzling to the two is that in addition to the power recovery of the braking system, there are also power recovery systems on the two drive shafts. These three power systems are connected to the electric field output by the engine, which is then rushed into the battery.

This kind of circuit method seems extremely unscientific.

Needless to say, the power recovery of the braking system is a relatively conventional way to obtain hybrid electricity. But what is the power recovery system on the bottom bracket used for?

Originally, the meaning of the existence of this system is to convert power into electricity as much as possible. Although I don't believe that the energy conversion rate of this system can reach nearly 100%, it is assumed that this thing is possible.

Then the two sets of power recovery systems on the propeller shaft are completely contrary to this set of technology similar to internal combustion electric vehicles.

This is because the power recovery system itself increases the loss of kinetic energy.

As for the transmission part, it is a little different from the two of them's understanding of hybrid cars.

A conventional hybrid dual-engine car is equipped with a gearbox. Because as long as the internal combustion engine is the power output, there must be an effective transmission system.

Why?

Because the internal combustion engine cannot turn torque at low speeds. It's like a martial arts master, there is no strength to punch while standing still, and only by sprinting up and punching forward can you send out all your strength.

However, at high speeds, the output torque of the combustion engine is greatly reduced. It's still like a martial arts master, who runs too fast and doesn't have the strength to punch.

In summary, the operating speed range of an internal combustion engine is very narrow, only about 1000-4000 revolutions per minute.

This creates two more problems: the first is that there is no way to start the car, because the minimum operating speed is 1000 rpm. The second is that it can only be high-speed but not low-speed, or it can only be high-speed but not low-speed.

The gearbox and clutch exist because of this. So on the internal combustion engine, the gearbox is a rigid configuration. It is precisely because of this that the general engine is directly integrated with the gearbox to form a power system.

The motor of an electric vehicle has two characteristics: first, it can output high torque at low speed or even in a stationary state. The second is that the working speed range is particularly wide, from 0 revolutions per minute to 7000 revolutions per minute.

Combining these two points, the motor can be fun even without a gearbox.

Fundamentally speaking, Li Fanyu's so-called hybrid technology is a template for an electric vehicle with its own generator, so it does not need to be shifted.

But paradoxically, the car also has a gearbox.

Seeing that the two were puzzled, Li Fan pointed out with a smile, Xu Fufang and Wang Yu finally understood the meaning of the existence of this gearbox;

That's weird.

"Brother Fan, this set of things is a bit complicated. Looking at the drawings alone, I really can't believe that it can surpass or even achieve the emission savings and efficiency improvement effects of the existing dual-engine hybrid technology. Are you really going to apply this thing directly to Type II buses?"

Li Fanyu nodded, "Of course, although the kinetic energy provided by the internal combustion engine is used as a power generation device, it must be more straightforward without direct electricity." There is certainly no pure battery environmental protection. However, for users who have imperfect charging base station construction or need to travel for a long time, this system can be regarded as a transitional solution. ”

"But Brother Fan, have you ever thought about it. Even if this technology can work, but is it too complicated? Let's talk about the main components: the battery pack plus the cooling system, the motor, the displacement electric field, three power recovery systems plus the gearbox with the built-in power recovery system, and the internal combustion engine for power generation. Unless you're really, really fuel-efficient, otherwise, isn't it a bit ...... to have such a large vehicle cost? Chicken ribs?"

That's a problem.

Li Fanyu thought for a while, recalled the parameters of the space description when exchanging this set of hybrid technology, and then waved his hand: "Don't worry about that for now!

Faced with Li Fanyu's casual attitude, Wang Yu and Xu Fufang rolled their eyes in unison.

……

But when the first hybrid system for testing was born and tested, Xu and Wang Yu were stunned. According to the preliminary simulation test, this pseudo-hybrid technology, which does not look like four or six, has an almost amazing performance in terms of fuel consumption!

Under the simulated conditions of three tons of dead weight and two tons of load, this system can run 1,000 kilometers with 80 liters of gasoline.

If it is placed on the general hybrid car, such a performance is not shocking, and it can be called decent.

However, for a large bus like a bus, it is already unexpected.

After all, according to Li Fanyu, this is just a transitional plan. In the face of such a positioning, what other flaws can this hybrid technology have?

The engineers at the Ministry of Power are excited.

Under the leadership of Xu Fufang and Wang Yu, they immediately began to upgrade the Type II bus. The castrated version of the Type II electric bus, which was originally designed to have a reduced battery pack and reduced motor power, just left a lot of layout space to accommodate the implantation of hybrid systems.

The technical direction was determined, and Li Fanyu handed over some of the rest to Xu Fufang and Wang Yu.

But he himself failed to be the shopkeeper.

After a period of preparation, Zhengxin Group's fashion brand "Xfan" has been successfully registered, and has carried out publicity and momentum in China.

In order to cooperate with this brand that enhances the brand recognition of Zhengxin and the recognition of high-end customers, Li Fanyu still has a lot to do.

But for Zhengxin, a car company, if it wants to gain huge attention, there are just a few ways: Li Fan's foolish scandal/Li Fan's foolish death/Zhengxin technology breaks the existing pattern.

But beyond that, there is one of the simplest and crudest ......

Over there...... A new car that blows the sky!
