氧传感器波形分析在电喷发动机故障诊断中的应用

Application of Oxygen Sensor Wave-Shape Analysis in Trouble Diagnosis of Electronic Fuel Injection Engine

概括了氧传感器故障波形分析的方法,指出当氧传感器的实测波形与正常波形不相符合时,电喷发动机就存在故障,并举例说明了氧传感器的波形分析在电喷发动机故障诊断中的应用。

The methods for analyzing oxygen sensor wave-shape trouble are systemically summarized in the paper, it is being pointed out that the disaccording between the actual wave-shape and the standard wave-shape of oxygen sensor induces troubles of electronic fuel injection engine. By giving an example, the paper explains how the wave-shape analysis of oxygen sensor is applied to the trouble diagnosis of electronic fuel injection engine.
