Abstract
Systems, methods and techniques for exhaust gas recirculation are provided. The system includes controlling the mixing of exhaust flow from at least one cylinder of an engine with air in an air intake system prior to combustion in response to an EGR fraction deviation condition. 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 to mitigate or prevent the EGR flow from deviating from an expected EGR fraction.
