<P>PROBLEM TO BE SOLVED: To execute the self-regeneration processing of a DPF without deteriorating the operation efficiency of a construction machine. <P>SOLUTION: This DPF self-regeneration device for the construction machine equipped with the DPF 14 for collecting a particulate matter in exhaust gas includes a clogging determination means 64 determining the state of the clogging of the DPF 14 based on the operation state of an engine 7 during the operation of the construction machine, and an engine key state detection means 9 detecting the on/off-state of an engine key after the operation of the construction machine is stopped. When the clogging determination means 64 determines that the DPF 14 is in a clogging state and the engine key state detection means 9 detects the off-state of the engine key, a regeneration control means 65 executes the self-regeneration processing of the DPF 14 without stopping the engine 7. <P>COPYRIGHT: (C)2011,JPO&INPIT |
