众所周知,内燃机必须借助外力起动后,才能自行运转。早期的内燃机是靠手摇或脚踏等人力方法起动。为了满足人们不断追求操作简便及舒适性的需要,人们设计了电动机起动发动机系统。早期内燃机电起动系统的操作,不像现在这样简便,是利用脚踏的力量,闭合大功率接触开关,同时靠脚 It is well known that internal combustion engines must be started by external force before they can operate on their own. Early internal combustion engine is by hand or foot and other manpower methods start. In order to meet people’s continuous pursuit of ease of operation and comfort needs, people designed the motor starting engine system. Early internal combustion engine starting system operation, not as easy as now, is the use of foot power, closed high-power contact switch, while foot
