某发动机低频不稳定燃烧的消除

Elimination of low-frequency unstable combustion phenomenon of a certain engine

根据发动机热试车出现的低频不稳定燃烧现象,分析了产品的故障模式,建立了相关零组件模型。对相关零件进行了改进设计,消除了发动机低频不稳定燃烧现象。

The failure mode of an engine is analyzed and the model of a corresponding part is established in this paper based on the phenomenon of low-frequency combustion instability occurred in hot fire testing of the engine. The phenomenon of the low-frequency unstable combustion was eliminated after the design improvement of a corresponding part.
