摘　　要：电喷发动机中的氧传感器是电子控制燃油喷射系统中重要的传感器之一。氧传感器可以对发动机气缸内部的燃烧起监控和指示作用。笔者在电喷发动机故障诊断试验台上,通过测取发动机相关参数及氧传感器波形等信号,验证氧传感器在诊断电喷发动机故障中的作用。The oxygen sensor of electronic fuel injection engine is one of important sensors in electronic control gasoline injection system.The oxygen sensor can play the role of monitoring and instruction to internal combustion in engine cylinder.This paper verifies oxygen sensor in the diagnosis of the role of EFI engine failure through the measured engine-related parameters and waveforms,such as oxygen sensor signal and the experimental rig of failure simulation for electronically controlled engine on the fault diagnosis EFI engine test stand.
