Abstract

A particulate regeneration system (26) for an engine (10) is disclosed. The particulate regeneration system may have a particulate filter (28) configured to remove particulate matter from a flow of engine exhaust, and a diesel oxidation catalyst (30) located upstream of the particulate filter to facilitate oxidation of the trapped particulate matter. The particulate regeneration system may further have a regeneration device (32) located upstream of the diesel oxidation catalyst and configured to selectively heat the exhaust above an oxidation temperature of the trapped particulate matter, and a selective catalytic reduction device (36) located downstream of the particulate filter to remove NOx from the engine exhaust. The particulate regeneration system may also have a controller (34) in communication with the regeneration device and the engine. The controller may be configured to modify engine operation in response to initiation of a regeneration event.
