Abstract: An exhaust system (16) of a diesel engine (10) has a diesel particulate filter (18) for treating exhaust gas. When trapped soot has accumulated to an extent that may affect performance of the filter, an engine control system (12) forces combustion of trapped soot by increasing exhaust back-pressure using a control device (20) such as a back-pressure control valve or vanes of a variable geometry turbocharger.

Abstract: De-sulfurizing a NOx adsorber catalyst (48) without significantly increasing the temperature of exhaust gases leaving the engine exhaust manifold (42) by using a diesel oxidation catalyst (46) between the exhaust manifold (42) and the NOx adsorber catalyst (48) to elevate exhaust gas temperature entering the NOx adsorber catalyst (48) to suitable de-sulfurizing temperature through control of certain aspects of engine operation (24, 28, 52).

Abstract: A control system (FIG. 4 ) for controlling regeneration of a DPF comprises a favorable-condition-based control section ( 52 ), a regular control section ( 54 ), and a regeneration termination control section ( 56 ). Section ( 54 ) initiates regeneration when the actual soot loading of the DPF becomes sufficiently large to mandate initiation of regeneration. Section ( 52 ) initiates regeneration when the actual soot loading reaches an amount less than the amount at which section ( 54 ) mandates regeneration, provided that selected engine operating conditions disclose conditions favorable for regeneration. Section ( 56 ) terminates regeneration when soot loading is reduced to some minimum amount or when conditions for continuing regeneration become unfavorable. By burning trapped soot during favorable conditions, the mandatory regeneration is postponed. This can lower the average amount of trapped soot in the CDPF, thereby lowering the average back-pressure on the engine.
