蒸汽机在工业和运输业发动了一场革命。尽管它和汽油机竞争了二十多年,但是它实在太不符合实际要求了,要花很长的时间去启动,从而不能成为公路上的主导者。从作为驱动工业机械化的稳定的引擎开始,内燃机便成为引发20世纪运输革命的“主角儿”。这场革命中诞生了又轻又高效的发动机,这可是机动车能为大众运输服务的必备条件哦! Steam engines have revolutionized industry and transportation. Although it competed with the gasoline engine for more than two decades, it did not meet the actual requirements. It took a long time to get started and could not become a leader on the road. Starting from a stable engine that drives industrial mechanization, the internal combustion engine has become the “protagonist” of the transport revolution that led to the twentieth century. This revolution gave birth to a light and efficient engine, which is a prerequisite for the mass transit service of motor vehicles!
