<p><P>PROBLEM TO BE SOLVED: To not only request regeneration for sharp increase of PM (Particulate Matter) generation quantity due to abnormality of an engine component or the like, but also execute necessary process at appropriate timing even when regeneration operation in response to the request is not executed in a DPF (Diesel Particulate Filter) regeneration control device for a vehicular diesel engine for travelling. <P>SOLUTION: This device includes: an operation corresponding PM accumulation quantity operation means 21 operating PM accumulation quantity on a DPF from an engine operation state; a differential pressure corresponding PM accumulation quantity operation means 22 operating PM accumulation quantity from differential pressure between an upstream side and a downstream side of the DPF; a forced regeneration request means 23 requesting forced regeneration which is done with a vehicle stopped when either of both PM accumulation quantities exceeds a reference value; and a limit process request means 24 requesting limit attainment process in case that PM accumulation quantity on the DPF reaches a limit if the PM accumulation quantity corresponding to differential pressure or a value according to the same reaches a limit value higher than the reference value, when it is determined that the forced regeneration is necessary since the PM accumulation quantity corresponding to differential pressure exceeds the reference value. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
