摘要： While an engine (10, 10A, 10B, 10C, 10D, 10E) is operating, a control system (22) processes data for certain engine operating parameters to calculate a quantity of exhaust gas needed to satisfy an exhaust gas recirculation requirement. If a primary EGR control loop (34) alone can satisfy the calculated quantity of exhaust gas, a secondary EGR control loop (36) is closed while the primary EGR control loop is controlled to satisfy the calculated quantity. When the processing determines that the primary EGR control loop alone cannot satisfy the calculated quantity, the secondary EGR control loop is open concurrently with the primary EGR control loop and both the primary EGR loop and the secondary EGR loop are controlled to cause the combined flow of exhaust gas through the primary EGR control loop and flow of exhaust gas through the secondary EGR control loop to satisfy the calculated quantity.

摘要： The control system controls lean-rich modulation of fueling using a set of engine specific fueling parameter maps. One set of maps is a set of lean fueling maps, and another set is a set of rich fueling maps. The two map sets each comprise a fuel injection pressure map, an EGR valve opening map, and a VGT valve opening map, established for the particular diesel engine, with neither form of modulation requiring post injection. The strategy is represented by a flow diagram and is useful in regenerating an NOx adsorber catalyst in the engine exhaust system in a manner that controls torque so that the regeneration process is transparent to the operator of the vehicle, while producing significant fuel savings.
