Abstract

A two component metal oxide semiconductor gas sensor system has been used to investigate the detection of NOx in a combustion engine environment. The results show good detection levels of NOx and high chemical stability in the combustion engine environment. Additional tests demonstrated low cross sensitivity to impurities such as C3H8 and consistent gas response behavior in variable oxygen (0.1 – 10%) environments.
