Abstract: Methods and systems of recirculating exhaust gas in internal combustion engines are disclosed. An internal combustion engine includes a set of cylinders, an intake system disposed in fluid providing communication with the set of cylinders, an exhaust system disposed in fluid exchanging communication with the set of cylinders, and a controller. In response to a detected recirculation condition, the controller prevents fluid communication between the intake system and a subset of the set of cylinders and recirculates exhaust gas between the subset of the set of cylinders and the exhaust system.

Abstract: Systems and methods are provided for managing low temperature NOx and HC emissions, such as during a cold start of an internal combustion engine. The systems and methods include storing NOx and HC emissions at low temperatures and passively releasing and treating these emissions as the temperature of the exhaust system increases.
