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.
