ABSTRACT:
A method of operating an internal combustion engine includes operating the engine in a first combustion mode. The method also includes switching operation of the engine to a second combustion mode. The method includes directing an exhaust stream of the engine into contact with a NOx adsorber substantially only during the operation in the second combustion mode.
