- A new generation of on-board automotive sensors are needed for diagnosis and control of engines and catalytic converters. With regard to catalytic converters, the intent of these regulations is to ensure that the vehicle operator is informed when emission control system are no longer performing adequately. In order to be commercialized, sensors for emission control must meet certain criteria, including low cost, reliability, and manufacturability. We have been developing solid state electrochemical sensors for emission control. Most recently, our work has focused on the development of hydrocarbon sensors for monitoring catalytic converter performance. Previous work was concerned with the development of an oxygen sensor having appropriate sensitivity for lean-burn engines. Operational limits for oxygen sensors have been defined and new materials have been developed for hydrocarbon sensors. Technical results are presented here as well as challenges to be met in the development of materials and designs for new chemical sensors for monitoring automotive emissions.
