摘要

在理论上

汽车氧传感器电压输出特性可用能斯特方程进行计算和描述

但在实际制造上

由于材料的选取、制造工艺以及工作温度等诸多因素

造成氧传感器的电压输出特性偏离理论曲线

另外

随着汽车氧传感器服役时间的增加

也不可避免地会出现这种偏差。通过试验和研究

提出350℃和850℃是评价汽车氧传感器电压输出特性的关键温度点

评价混合气浓状态λ应选择0.97

稀状态应选择1.10。

Abstract

In theoy automobile oxygen sensors output-voltage characteristics can be described according to Nernst’s equation.But because of the material

produce process and ambient temperature

the voltage output deviates theoretic curve.The output-voltage of the oxygen sensor is studied.The result shows that 350 ℃ and 850 ℃ are key point in evaluating output-voltage characteristics of oxygen sensor

λ=0.97 for rich and λ=1.10 for lean is suitable.
