摘要： The present invention relates to an oxygen concentration detector to be used in a system which can simultaneously dispose of the three harmful elements in automotive emissions, i.e., unburnt hydrocarbons (unburnt HC), carbon monoxide (CO) and nitrogen oxides (NOx) through reaction with catalyst. In said detector an oxygen concentration cell comprises a solid electrolyte of a special ceramic material characterized by oxygen ion-conductivity; and the oxygen concentration of a measured gas can be analyzed by measuring the electromotive force generated through a difference in the oxygen partial pressure between the measured gas and a reference gas.
