摘要
随着汽车工业的发展,传统汽油机尾气对环境的污染问题一直备受关注。现代汽车发动机汽车普遍使用三元催化转换器以减少排气污,为提升三元催化转换器的转化效率,适应发动机控制空燃比反馈控制需要,氧传感器是必不可少的元件。对装有排气氧传感器的电控燃油喷射发动机,如果在运转中出现怠速不稳、加速无力、油耗增加、尾气超标等故障而供油、点火装置又无其他故障,那么极有可能是氧传感器及相关线路出了问题。
With the development of the automobile industry,the environmental pollution caused by the exhaust of traditional gasoline engines has always been a concern.Modern automobile engines generally use three-way catalytic converters to reduce exhaust pollution.In order to improve the conversion efficiency of three-way catalytic converters and meet the needs of engine control air-fuel ratio feedback control,oxygen sensors are indispensable components.For an electronically controlled fuel injection engine equipped with an exhaust oxygen sensor,if there are faults such as unstable idle speed,weak acceleration,increased fuel consumption,excessive exhaust gas and other faults during operation,and there are no other faults in the fuel supply and ignition device,then it is most likely to be oxygen There is a problem with the sensor and related wiring.
