Integrated WGS/ECD Exhaust Treatment Device for Internal Combustion Engine Having an EGR Loop

Abstract: 

An integrated water-gas-shift (WGS) and emissions control device (ECD) catalyst for treating exhaust from an internal combustion engine. The engine is assumed to have an EGR loop, such that exhaust is recirculated back to the engine's intake. A WGS catalyst on the EGR loop, for conditioning the EGR flow, is integrated with a catalyzed ECD on the main exhaust line, for reducing pollutant emissions.
