汽车发动机氧传感器原理及数据诊断分析

Principle and Data Diagnosis Analysis of Automobile Engine Oxygen Sensor

汽车发动机氧传感器对发动机运行至关重要,发动机的动力、状态以及排气等均受到氧传感器的影响。传统氧传感器和宽频氧传感器的技术原理及数据诊断分析上有相关,也有不同点,以上汽通用汽车某些车型为例,对两种传感器的工作原理、线路、信号波形、相关数据等进行分析,为汽车发动机氧传感器的检修提供了具有较强的参考意义的故障诊断分析方法。

The car engine oxygen sensor is essential to engine operation,the driving force,state,and exhaust gas of the engine are affected by the oxygen sensor.The technical principles and data diagnostic analysis of traditional oxygen sensors and wide frequency oxygen sensors are related,and there are different points.Some models of the above steam are used as an example.Analyze the working principle,line,signal waveform,related data,etc.of the two sensors.For the maintenance of the car engine oxygen sensor,it provides a fault diagnosis method with strong reference significance.
