汽车氧传感器根据工作原理可分为3类:(1)浓差型;(2)极限电流型;(3)氧化物半导体型。汽车氧传感器是电喷发动机控制系统中关键的传感部件,电极是氧传感器中最重要的组成部分。目前,低温(600℃)下以银电极为主;高温(600～900℃)下则以铂电极为主,但因其价格昂贵,金属陶瓷复合电极正逐渐代替铂电极;一些半导体金属氧化物电极也表现出一定的应用前景。
Automotive oxygen sensors according to the working principle can be divided into three categories: (1) concentration-type; (2) limit current type; (3) oxide semiconductor type. Automotive oxygen sensors are key sensing components in EFI engine control systems and electrodes are the most important component of oxygen sensors. At present, the silver electrode is mainly used in the low temperature (600 ℃) and the platinum electrode in the high temperature (600 ℃ to 900 ℃). However, due to its high price, the cermet composite electrode is gradually replacing the platinum electrode. Some semiconducting metal oxides Electrodes also showed some application prospects.
