摘要:
An aircraft engine includes a cylinder assembly knock detection and suppression system. The knock detection and control system includes a set of knock detection sensors and an engine controller. Each cylinder assembly of the aircraft engine carries a knock detection sensor and each knock detection sensor is electrically coupled to the engine controller. During operation, each knock detection sensor transmits signals to the engine controller where the signals correspond to detected cylinder assembly vibrations. As the engine controller receives input signals from the sensors, the engine controller filters the input signals to distinguish the input signals as being associated with either knocking or as a non-knock event. In the case where the engine controller detects the occurrence of one or more knock events in a particular cylinder assembly, the engine controller automatically reduces the spark timing for that cylinder assembly and/or increases the volume of fuel delivered to that cylinder assembly.
