在排放法规对汽车尾气排放要求日益严格的今天,传统的氧化锆传感器和氧化钛传感器已逐渐不能满足要求。空燃比传感器在汽车上的应用越来越多,本文通过介绍三元催化转化器工作效率及氧传感器输出特性、空燃比传感器工作原理及其输出特性说明了全范围空燃比传感器的取代传统氧传感器必将成为一种趋势。
Today, emission regulations increasingly stringent requirements on vehicle exhaust emissions, the traditional zirconia sensor and titanium dioxide sensor has gradually failed to meet the requirements. Air-fuel ratio sensor in the automotive applications more and more, this paper describes the three-way catalytic converter efficiency and oxygen sensor output characteristics of the working principle of air-fuel ratio sensor and its output characteristics of the full range of air-fuel ratio sensor to replace the traditional oxygen sensor Will become a trend.
