Abstract: Systems and methods for internal combustion engine operation with exhaust gas recirculation and turbocharging are disclosed. The systems include an exhaust gas recirculation loop for recirculating exhaust gas flow from a first portion of the cylinders of the engine into an intake system prior to combustion. The system further includes a turbine with first and second inlets for receiving exhaust gas flows from respective first and second parts of the exhaust gas of the remaining portion of the cylinders.

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.
