摘要
氧传感器是影响三元催化转化器催化净化效果的一个关键元件。通过运用气体扩散理论对汽车用氧传感器误差的产生机理做了详细的分析,并对氧传感器误差对判断三元催化转化器工作状况的影响作了理论说明,对进一步改善发动机空燃比的控制精度,减少汽车尾气排放具有理论指导作用。
Oxygen sensor is a key component which affects the purification for three-way catalytic converter. This thesis analyzes the error mechanism of automobile oxygen sensor with gas diffusion theory in detail, and explains the effect of three-way catalytic converter＇s work status by oxygen sensor＇s errors in theory. It will play an important role in improving the control precision of air fuel ratio and reducing vehicle emissions.
