PROBLEM TO BE SOLVED: To solve a problem where calculating only an estimated accumulation amount of particle matters on the basis of an operation state of a diesel engine is not enough for a purpose to execute a regeneration treatment of a diesel particulate filter at the right time.SOLUTION: A soot accumulation calculation and display device 20 comprises: a first calculation section 21 which calculates a first estimation value of a present soot accumulation amount; a second calculation section 22 which calculates a second estimation value of the present soot accumulation amount on the basis of operating hours of an internal combustion engine from a start time of a latest regeneration treatment of a filter, among previously conducted regeneration treatment of the filter, to a present time and a preliminarily obtained first relation between the operation hours of the internal combustion engine and the soot accumulation amount; a decision section 25 which decides a maximum estimation value of the first and the second estimation values; and a display section 26 which performs a display of the maximum estimation value decided by the decision section 25. |
