Chapter 1193 A New Road

"Hybrid system," Zhang Qihang said directly without going around in circles with Cai Xiangdong: "Cai Dong, tell me, if we apply a hybrid system in the commercial vehicle field, what will be the result?"

Cai Xiangdong frowned suddenly.

Don't get me wrong, Cai Xiangdong's frowning is not to express dissatisfaction with Zhang Qihang's proposal, but to seriously think about what Zhang Qihang said: Is it a hybrid system...

Comrade Lao Cai doesn't know much about hybrid systems, but coincidentally, because of Zhang Qihang, he still has a good understanding of hybrid systems for passenger cars. He knows that the biggest benefit of hybrid systems is fuel economy. Take the hybrid system on Sylphy as an example. Compared with the fuel version, the fuel-saving efficiency of the hybrid system is as high as 45%!

For a commercial vehicle that runs tens of thousands of kilometers almost every month and has an annual mileage of 15 to 25 kilometers, the fuel saving rate of 45% is not a small number. You must know that the largest commercial vehicle Cost expenditure is fuel expenditure. Calculated on the basis of an average fuel consumption of 35 liters per 20 kilometers and a slightly higher median of 70000 kilometers per year, the annual fuel consumption of a commercial vehicle is 4.6 liters. With reference to the current diesel price of about 45 yuan per liter Price, if the hybrid version of the commercial vehicle can also achieve a 14.49% fuel-saving effect, theoretically it can save 35 yuan in fuel expenses per year, even if the fuel-saving effect is reduced to 11.27%, the annual fuel cost saved is as high as [-] [-] yuan...

If you really don’t know, when you calculate it, Comrade Cai is shocked by the result of his own calculation: Even if a semi-trailer is used for 10 years, after 10 years, the fuel cost saved will be as high as millions?
Even if this hybrid system is indeed a bit expensive, compared to the millions of fuel expenses saved in the entire life cycle, Comrade Cai believes that even a semi-trailer equipped with a hybrid system costs more than an ordinary fuel semi-trailer. It is also extremely cost-effective for car owners.

So here comes the question, even if self-employed people who only buy one or two cars for transportation feel that the trailer head is too expensive and are reluctant to spend the money, but corporate users who pay more attention to the benefits of the whole life cycle, will they be impressed by the hybrid version of the trailer head? interest?

Of course!
Almost in a moment, Comrade Cai came to the conclusion that a car can save millions of fuel expenses for the company during its entire life cycle. Millions of profits, even a small and medium-sized transportation company with only 500 to [-] vehicles can make an extra [-] million in profits a year!
With this premise, for those transportation companies, can the extra money from purchasing the front of the car be called money?
However, Cai Xiangdong is the chairman of the group after all. Although he is very interested in Zhang Qihang's proposal, he will not be overwhelmed by Li Hongfei's words. After pondering for a while, he asked: "Mr. The idea is indeed very reasonable, I also know the advantages of the hybrid system, the biggest feature is fuel economy, you also fancy this point, right?"

"Yes, I also took a fancy to this point," Zhang Qihang nodded affirmatively: "After all, compared with passenger cars, our commercial vehicle users' biggest expenses in the coming year are fuel expenses and highway tolls, among which fuel expenses are even more important. The big one among the big ones, and the biggest feature of the hybrid system is fuel economy, which is also my intention."

"That's the reason." Cai Xiangdong nodded again and again, and then asked Zhang Qihang: "What do you think is the fuel-saving effect if a hybrid system is used in the commercial vehicle field?
In addition, you also know the use of commercial vehicles in our country. Can the power meet the needs of users?In terms of power, is it also necessary to optimize the engine like a passenger car? "

Cai Xiangdong's questions were on point.

If it is a hybrid commercial vehicle, how much fuel-saving effect can it have?
Moreover, commercial vehicles are used as means of production, and any car owner must try his best to avoid the situation of no-load. Not only is he trying his best to pursue full load, but he is even desperately overloading--who hasn't heard of the name "Hundred Ton King"?

So here comes the question, if the vehicle is seriously overloaded, and at the same time the car has to climb uphill in the southwest region or the Qinling Mountains, how should the hybrid gearbox be designed to ensure normal use?

Compared with these problems, the engine problem is a minor problem.

Of course, this small is only relatively "small". Although Sinotruk Group is engaged in commercial vehicles, but after working with Zhang Qihang for so long, Cai Xiangdong also knows that it is necessary to maximize the performance of the hybrid system. To optimize the working conditions of the engine, the engine of the hybrid system of Stealing Oil Otter is a gasoline engine that adopts the Atkinson cycle. The engine of this hybrid system of Huateng Group also adopts the Miller cycle. design.

So here comes the question, since the engine in the hybrid system used in passenger cars needs to be specially optimized for hybrid working conditions, does the hybrid system of commercial vehicles need targeted optimization of the engine?The answer is of course no doubt.

Zhang Qihang said: "In terms of fuel-saving effect, although Huateng Group is engaged in passenger cars, we have also done calculations on the application of hybrid systems to commercial vehicles. According to different hybrid systems, it can roughly achieve 35% % to 48% fuel savings..."

Cai Xiangdong was a little surprised, and before Zhang Qihang finished speaking, he couldn't help interrupting him, asking, "Can you save so much fuel?"

"It's a bit beyond imagination, isn't it?"

Seeing Cai Xiangdong nod, Zhang Qihang smiled and said: "You can understand this matter after a little thought, especially in terms of kinetic energy recovery. Commercial vehicles have a greater weight, and the same taxiing distance can recover more energy. , the fuel-saving effect is even more outstanding.”

Cai Xiangdong thought for a while, then nodded in agreement: "That's the truth."

Commercial vehicles are different from passenger cars. For ordinary family cars, 35 meters to 42 meters is the distance from a speed of 100 kilometers per hour to the stop of a small car. Under the premise, if you want to go from a speed of 100 kilometers per hour to a complete stop, it will even take one or two kilometers. If such a long braking distance is used to recover energy, how much electricity can be recovered?

There is a lot of braking energy recovery, so in turn, the natural engine running time is relatively short, and the engine running time is short, can it save fuel? In addition, the optimized engine can run at high efficiency for a long time Zone, avoiding the most fuel-consuming starting and accelerating links, naturally you can save more fuel...

"As for whether the power can meet the needs of the domestic logistics market," Zhang Qihang continued, "These are actually not a problem. The new generation of hybrid system developed by Huateng Automobile can realize the series and parallel connection between the motor and the engine. In theory, the maximum power can reach the sum of the power of the motor and the engine. In terms of gearbox design, Huateng Automobile can provide corresponding assistance.

As for the engine, Huateng Motors also has some experience in adjusting the Miller cycle, and can carry out corresponding technical cooperation with Weichai to shorten the development time of the special hybrid diesel engine. "

Speaking of this, Zhang Qihang felt a little emotional.

Speaking of it, hybrid commercial vehicles have always been in a state of "popular but not popular" in the history of China's commercial vehicle development. In the future, even pure electric trucks will develop better than hybrid vehicles, but that is really because of the hybrid version. Is your commercial vehicle bad?Zhang Qihang believes that this is not the case. The most fundamental reason is that the hybrid version of commercial vehicles was not born at the right time.

In the field of commercial vehicles in China, 2008 is recognized as the first year of the development of AMT automatic transmissions for commercial vehicles. However, it was not until 2019 that the annual sales of commercial vehicles with automatic transmissions exceeded 10000. Note that this 10000 vehicles was not achieved by a single brand. The sales of commercial vehicles with automatic transmission exceeded 10000 units, but the sales volume of commercial vehicles with automatic transmission exceeded 10000 units in the whole industry.

The development of automatic transmission models is still the same, and the development of hybrid models is naturally more conceivable. It was not until 2016 that the project team of Qinghua University developed the first domestic heavy-duty special hybrid for commercial vehicles based on AMT automatic transmission. This also supports the completion of the project development, and it will take a lot of time to improve this gearbox. The result is that when Qinghua University’s special hybrid AMT gearbox for commercial vehicles is basically ready for large-scale promotion When the conditions are met, the time has come around 2020, and at that time, Pharaoh's 2AT/4AT pure electric commercial vehicles have been promoted and launched on a large scale.

As a result, the embarrassing situation of the hybrid system in the field of commercial vehicles has been caused: in terms of price, because there is no industrial chain, the price of hybrid models remains high, and there is not much price compared to pure electric models. Advantages; in terms of daily cost, it cannot be compared with pure electric commercial trucks that can only be charged.

As a result, more and more transportation companies have begun to choose pure electric vehicles for short-distance urban transportation and point-to-point transportation in the province; at the same time, traditional pure fuel commercial vehicles are also developing rapidly, and even the sales of automatic transmission It is also rising steadily, only the hybrid version has become "two do not rely on".

Now, the time has returned to 2007. Zhang Qihang believes that this time period is the most suitable time to promote hybrid commercial vehicles: pure electric commercial vehicles have not yet appeared. As for the price, although the price of hybrid commercial vehicles is definitely higher than fuel The new version is more expensive, but with its huge fuel-saving advantages, it can still attract a considerable number of consumers.

Cai Xiangdong thought about it carefully, nodded, and asked Zhang Qihang in a low voice: "Mr. Zhang, have you calculated the cost?"

"Roughly calculated, but in the absence of a confirmed technical route, I can only give a rough figure," Zhang Qihang replied: "It is about 1.2 to 2.5 times that of the current fuel version."

"1.2 to 2.5 times..."

Cai Xiangdong frowned, thinking.
