氧化锆式车用氧传感器的原理与检修

Principle and Maintenance of Zirconia type Automobile Oxygen Sensor

氧传感器是电喷汽车上使用最普遍的传感器之一,它的好坏不但要影响汽车的尾气排放,还会直接影响发动机的工况。另外,造成氧传感器信号失常的原因,除了氧传感器本身,还涉及到发动机的工况、发动机电脑、线路等诸多因素,从维修的角度和常规的做法,首先应该断定和排除氧传感器本身是否真的存在故障。

Oxygen sensor is one of the most common sensor in EFI cars,it not only affects the car＇s exhaust emission,but also directly affects the engine working conditions.In addition,the causes of oxygen sensor signal abnormalityis also related to the engine＇s working condition,engine computer,line,and many other factors,from the point of maintenance and routine practice,first of all should judge and excludeoxygen sensorfault.
