On the Applicability of Silicon Carbide Based Field Effect Sensors in the Control of Exhaust/Flue Gas After-Treatment Systems

Abstract

The performance of Silicon Carbide based field effect gas sensor devices, modified to enable long-term reliable operation with improved sensitivity to e.g., NH3 and CO at relevant temperatures for exhaust/flue gas emissions monitoring and control of combustion processes as well as after-treatment systems in automotive/stationary applications has been investigated with promising results.
