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.

Abstract: A method includes: receiving an inlet temperature of a selective catalytic reduction system; comparing the inlet temperature to a temperature setpoint; and adjusting at least one of a first exhaust manifold pressure setpoint for a first cylinder bank of an engine or a second exhaust manifold pressure setpoint for a second cylinder bank of the engine, based on the comparison.

Abstract: A system includes an internal combustion engine having a number of cylinders, with at least one of the cylinders plumbed to have a complete recycle of the exhaust gases from the cylinder. The system further includes the completely recycled cylinder having an EGR stroke cycle, and the non-recycled cylinders of the engine having an exhaust stroke cycle. The system includes the EGR stroke cycle being distinct from the exhaust stroke cycle. An amount and composition of the exhaust gases from the recycled cylinder are distinct from the amount and composition of the exhaust gases from the non-recycled cylinders, at least at certain operating conditions of the engine.
