ABSTRACT:
A compression ignition engine (10) for a motor vehicle has a control system (20) for processing data, one or more combustion chambers (12), and fuel injectors (18) for injecting fuel into the chambers. The control system controls lean-rich modulation of fueling using independent maps. One set of maps is a set of lean fueling maps, and another set is a set of rich fueling maps. The strategy is represented by a flow diagram (30) and is useful in regenerating a NOxadsorber catalyst (16) in the engine exhaust system (14) in a manner that controls torque so that the regeneration process is transparent to the operator of the vehicle.
