摘　　要：对波音737NG飞机发动机滑油滤旁通故障报警案例进行了分析,从现场检查和故障报警原理入手,推断压差电门传送假信号可能引发发动机滑油滤旁通故障报警故障。This paper analyzes the case of fault alarm of oil filter bypass in Boeing 737 NG aircraft.Starting with the principle of field inspection and fault alarm,it is inferred that the false signal transmitted by differential pressure switch may cause the fault alarm failure of engine oil filter bypass fault.

关 键 词：发动机滑油滤 旁通故障报警 压差电门 假信号
