ABSTRACT:
Engine systems and methods for accomplishing regeneration of a NOx adsorber (28) using in-cylinder post-injection in a way that creates a lean-rich transition (FIG.3) for regenerating the NOx adsorber while attenuating engine torque output fluctuations during the transition without the necessity of using torque sensing to attenuate the fluctuations.
