Abstract: Systems and methods for exhaust gas recirculation are provided. The system includes a dedicated exhaust gas recirculation loop for recirculating exhaust gas flow from at least one dedicated cylinder of an engine into an intake system prior to combustion. The system further includes a low pressure exhaust gas recirculation loop for increasing the exhaust gas recirculation amount above that provided by the dedicated exhaust gas recirculation loop.

Abstract: Systems, methods and techniques for exhaust gas recirculation are provided. The system includes mixing exhaust flow from at least one cylinder of an engine with air in an air intake system prior to combustion. The exhaust flow from the at least one cylinder is accumulated prior to mixing and distributed into the intake air system in a controlled manner.
