摘　　要：目前航空汽油活塞发动机点火装置主流使用可靠性高的磁电机。由于起动机带动发动机启动时转速较低,航空磁电机的提前点火角度是固定的,不对磁电机增加额外的辅助启动装置,飞机无法正常启动,甚至可能损伤发动机。为了顺利正常地启动发动机,需要通过额外的装置在启动时既减小提前点火角度,同时又保证充足的点火能量。各发动机厂商对此研制了额外的辅助启动装置,本文对现有的三种类型辅助启动装置原理进行了归纳和特性分析,总结内容可以对通航维修工作有一定的指导作用。At present,the mainstream of aviation piston engine ignition device is still using magneto which is high reliability.Due to the low speed when the starter drives the engine to start,the advance ignition Angle of the aero-magneto is fixed,if the additional auxiliary starting device is not added to the magneto,the aircraft can not start normally,and may even damage the engine.In order to start the engine smoothly and normally,it is necessary to reduce the advance ignition Angle while ensuring sufficient ignition energy through additional devices.Various engine manufacturers have developed additional auxiliary starting devices for this purpose.This paper summarizes the principle and characteristics of the existing three types of auxiliary starting devices,and the summary content can have a certain guiding role for navigation maintenance work.
