点火系统工作直接影响起动性能、发动机功率、经济性以及工作的可靠性。在实际工作中,点火系统发生的问题比较多,在活塞式发动机中2/3的故障与点火系统有关,其中尤其是系统中最复杂的核心部件磁电机的故障较多。本文通过对磁电机的易损件和典型故障进行分析,为外场机务维护人员提供磁电机在维护工作中需要的基础数据和排除方法,提高维护工作效率,提高飞机出勤率,降低人力和物力成本消耗,保证飞行安全。
Ignition system work directly affects the starting performance, engine power, economy and job reliability. In practical work, there are many problems with the ignition system. Two-thirds of the failures in the piston engine are related to the ignition system, and in particular, there are more faults in the magneto, the most complicated core component in the system. In this paper, we analyzed the consumable parts and typical faults of the magneto, provided the basic data and troubleshooting methods needed by the magneto in the maintenance work for the field maintenance personnel to improve the work efficiency, improve the aircraft attendance, reduce the manpower and material costs Consumption, to ensure flight safety.
