排气氧传感器（EGO)是α闭环控制的反馈信号传感器，它将排气中氧气的浓度信号送到ECU，使ECU将α保持在14.7左右，以确保三元催化转化装置有效。由于EGO反映了混合气φa 的情况，又称λ 传感器。
因此应用氧传感器进行反馈的目的在于实现电喷并保证三元催化反应器的净化效果，解决功率、油耗和排气污染之间的矛盾。
So the purpose of applying oxygen sensors to keep feedback is to fulfill electronic fuel injection and solve the contradiction among power, oil-consumption, and exhaust pollution.
试验研究了摩托车在EUIII测试循环工况下的排气温度变化，以及对于两种氧传感器起燃时间、陶瓷体温度变化、动态响应特性和排放的影响。
The exhaust gas temperatures rise and variation during EUIII test cycle and its impact on the light-off time, ceramic temperature, dynamic response behavior and emission results were studied.
