<p><P>PROBLEM TO BE SOLVED: To provide an exhaust-gas processing device for a diesel engine, suppressing deterioration of fuel economy and a reduction in output. <P>SOLUTION: This exhaust-gas processing device for the diesel engine includes: a DPF; a means for presuming the amount of PM to be deposited on the DPF; a DPF-regeneration means; a DPF-regeneration control means; a storing means; a means for sending message to demand an accelerated regeneration; and an operation means for starting the accelerated regeneration. While normal regeneration processing is being continued S6 since it has started S2, time when a term T1 for reserving judgment as to the demand for accelerated regeneration has elapsed is taken as judging time T3 as to the demand for accelerated regeneration. At this judging time T3 as to the demand for accelerated regeneration, if the assumed value of the PM deposed amount exceeds a value J2 for judgment as to the demand for accelerated regeneration, the accelerated regeneration is deemed to be demanded. Then the DPF-regeneration control means allows the means for sending message to demand the accelerated regeneration to start S8 sending the message to demand the accelerated regeneration. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
