DPF SYSTEM FOR AN ENGINE GENERATOR A DPF system for an engine generator (E,G) that performs a recovery process on a filter (DPF), provided to remove particulate matter generated by combustion of fuel when an amount of the particulate matter in the DPF exceeds a predetermined value, the engine generator (E,G) performing the recovery process by carrying out an automatic recovery operation to raise a temperature of exhaust gas to combust the particulate matter, the system comprising: a dummy load (L) connected to the engine generator (E,G) when necessary; and control device (ECU) for allowing the engine (E) to perform a recovery preparation operation in such a manner that, once the amount of the particulate matter exceeds the predetermined value, the recovery operation is performed when the temperature of exhaust gas reaches a reference temperature, and the dummy load (L) is connected to the generator (E,G) to raise the temperature of exhaust gas when the temperature thereof fails to reach the reference temperature. 3 7, ( START AS1 STOP AS29 (MANUAL OPERATION) (MANUAL OPERATION) SET ENGINE TO ROTATE[ SET ENGINE TO AT RATED SPEED [--2 IDLING START S2 #(MANUAL OPERATION) $(MANUAL OPERATION) APGENEROATORON ~S3 CUT OFF LOAD S27 S4 OPERATE ENGINE GENERATOR IN NOMAL MANNER ' / S5 PM IN DPF INCREA SES (PM NTANEUIS BREDEY IS EXHAUST S7 AS TEMPERATURE EQUAL TO 0ON UOAI HIGHER THAN RECOVERABLE YEEAUOMATRC EMPERATURE?
