Not long ago, the "Lingqing" front-facing rear-drive hybrid system independently developed by Wuling Industry was officially released. Wuling Automobile, as an automobile brand that often makes shenche, is known for its people-friendly price and super high cost performance, although it is a joint venture with General Motors, but Wuling Automobile is an authentic independent automobile brand, and its predecessor comes from Liuzhou Power Machinery Factory.
From the information released so far, the "Lingqing" front-facing rear-drive hybrid system, using a tandem structure, somewhat similar to Nissan's e-power, using a high thermal efficiency 1.6L four-cylinder Atkinson cycle engine, high-efficiency generator and drive motor, high discharge rate power battery composed of hybrid system, and the high-power version will use a 2.0L naturally aspirated engine + motor composed of a hybrid system, the engine thermal efficiency of up to 39%.
The principle of this hybrid system is very simple, in simple terms, that is, all working conditions are driven by motors, the engine is only used as a power generation, it is the biggest difference from the series parallel hybrid is that in the case of high speed, the engine does not participate in direct drive, therefore, the structure is simple and efficient is very suitable for urban driving.
In the past two years, the domestic hybrid system can be said to be in full bloom, BYD Great Wall Geely Chery Wuling, have developed a hybrid system with low feed fuel consumption, but what makes many people wonder is why the Mercedes-Benz BMW Audi, which has stronger technical strength, is still using 48V light mixing and backward P2 architecture hybrid?
Is it because the technical strength is not enough? Obviously not, European car companies have led automotive technology for nearly a hundred years, although in the past three decades, and Japanese cars have won and lost in specific technical fields, but there is no doubt that the technical strength of European car companies, especially BBA, is beyond doubt. The two-motor series parallel hybrid system and tandem hybrid system, the difficulty is not in the hybrid system itself, the core difficulty lies in a high thermal efficiency engine, with the technical strength of BBA, to create a high thermal efficiency Ofkinson cycle engine, it should not be difficult. So what's the problem? It can only be the technical route.
In fact, since the 1990s, under the increasingly stringent emission policies, Japanese cars and German cars have diverged into two technical routes, and Japanese car companies have begun to focus on improving the thermal efficiency of the engine, and the other is to develop a gasoline-electric hybrid system, which is a more pragmatic solution. And European car companies, began to implement small displacement, turbo, in the hybrid system, European car companies do not invest much in research and development, choose P0-P2 architecture such a simple and rough hybrid route, this hybrid system, for the original power system is not much improvement, strong power, low research and development costs, can also achieve relatively low test fuel consumption, but the feed fuel consumption performance is not ideal.
Although the domestic hybrid system is in full bloom, but the grasp of the BBA such a joint venture car company technical discourse power, is still the German side, and BBA obviously believes that the current P2 architecture hybrid is enough to meet the demand, the next step of development focus on pure electric models, so do not want to invest too much in hybrid technology.
Therefore, European car companies do not develop similar to the dual motor series parallel hybrid system, not the reason for technical strength, but the reason for the technical route, there is also the so-called ship difficult to turn around, however, this also ushered in a good opportunity for the development of domestic cars, the next 10 years, will be the golden 10 years of hybrid model development, I hope that domestic cars can seize the opportunity and truly achieve the rise
