PROBLEM TO BE SOLVED: To provide a clogging warning device for particle oxidizing catalyst that notifies an operator of an indication that particle oxidizing catalyst clogs up, to prevent clogging of the particle oxidizing catalyst and prevent melting of the particle oxidizing catalyst.SOLUTION: A clogging warning device 100 for particle oxidizing catalyst includes: a calculation unit 118 configured to calculate a low load operation integration period by regarding periods in which temperature of exhaust flowing into a particle oxidizing catalyst 112 is low as positive, and integrating the periods: and a warning unit 119 configured to warn an operator of clogging of the particle oxidizing catalyst 112 when the low load operation integration period exceeds a threshold value.SELECTED DRAWING: Figure 1 |
