Research on Application Characteristics of Zirconia-Based High-Temperature NOx Sensors

The zirconia solid electrolyte SOFC (solid oxide fuel cell) has the characteristics of oxygen ion conduction function, high-temperature resistance, thermoelectric coupling effect, etc. A NOx sensor based on common and problems with in principle application. research objective this paper is to solve application smart sensors diesel vehicles or gasoline vehicles. Improvements performance can help emissions better meet requirements emission regulations. a regulatory required by for China’s Phase VI Vehicle Exhaust Emission Regulations Euro Regulations. key device improving efficiency reducing pollution. Moreover, its measurement includes dynamic immunity interference, response speed, accuracy, which are factors affecting vehicle emissions. This focuses impact physical structure, electrode characteristics, control strategies during An excellent strategy given analysis experimental testing. results show that meets exhaust aftertreatment systems.
