摘要： 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.

摘要： The present disclosure relates to methods, apparatuses and systems to manage exhaust gas expelled from cylinders of an internal combustion engine. An exemplary system may comprise at least one cylinder of the engine configured to operate as a dedicated exhaust gas recirculation (EGR) cylinder, and wherein substantially all exhaust gas expelled from the dedicated EGR cylinder is recirculated to an intake system of the engine. In one embodiment, the system may include a flow restrictor configured and arranged to restrict a flow of the recirculated exhaust gas to the dedicated EGR cylinder without restricting a flow of the recirculated exhaust gas to the remaining cylinders of the engine. In another embodiment, exhaust gas may be expelled from the dedicated EGR cylinder in pulsations, and the intake system may be configured to reduce an amplitude of the pulsations of the exhaust gas expelled from the dedicated EGR cylinder.
