先出一题:批量生产的汽车中都有哪些常见的动力形式?答案:燃油发动机、燃气发动机、纯电动、混合动力,以及插电式混合动力、燃料电池等。第二道题:它们中结构和技术最复杂的是哪种动力形式?答案:插电式混合动力。它将燃油汽车与纯电动汽车的两种动力形式整合在一起,组成既可加油又可充电的“两栖”汽车。整合在一起的两种动力系统既有分工又有协作配合,其结构设计和逻辑关系都需要精妙构思。近 First out a question: What are the common form of power in mass-produced cars? Answer: fuel engine, gas engine, pure electric, hybrid, plug-in hybrid, fuel cell and so on. The second question: Which of these dynamic forms is the most complex among them in structure and technology? Answer: Plug-in hybrid. It combines the two forms of fuel and pure electric cars into a “amphibious” car that refuel and recharge. The two powertrains that are integrated together have both division of labor and cooperation, and their structural design and logical relations require delicate ideas. near
