Wide Band용 NOx 센서 주변의 열·유동 특성에 관한 수치해석적 연구

Over the last decade, growing production of automobiles around the world enforce a strong concern globally on environmental pollution due to release of various hazardous gases. Such the pollutant gases exhausted by combustion of fossil fuels in automobile engines contain nitrogen oxides (NOx), unburned hydrocarbons, CO, and SOx. Thus, each country has a strong law enforcement for the reduction of various hazardous gases and effective to remove various hazardous gases has attracted attention in the system development. In these systems, the development of sensors capable of real-time feedback is required. In this study, NOx sensors for the automotive environment to develop a heat-flow characteristics is to analyze. And this research is used as a basis for the development of NOx sensor housing for Wide Band.
