| 摘要: | 为减少尾气的排放,汽车中大量使用了氧传感器及氮氧传感器。本文从测氧范围(窄域和宽域型)与核心部件结构(管式和片式)两个维度对氧传感器进行全面介绍;基于氧传感器的极限电流工作机理,详细阐述氮氧化物传感器的多腔工作模式,并对比分析其两腔和三腔结构的技术特点;同时,还基于氮氧化物传感器多腔工作模式的特点,提出了研发新型可燃气体传感器的思路。 |
| Abstract: | Oxygen sensors and nitrogen oxide sensors are used in large numbers in automobiles in order to reduce tailpipe emissions. This paper provides a comprehensive introduction to oxygen sensors from the perspectives of both oxygen measurement range (narrow and wide range type) and core component structure (tube and chip type). Based on the limiting-current working mechanism of the oxygen sensor, the multi-cavity working mode of NOx sensor is elaborated in detail, and the technical characteristics of two-cavity and three-cavity structure of NOx sensor are compared and analyzed. Meanwhile, based on the characteristics of multi-cavity working mode of NOx sensor, the idea of developing a new type of combustible gas sensor is also proposed. |
