<p>A regeneration device (22) carries out regeneration of the filter (21) of an exhaust gas purification device (18) by burning particulate matter collected in the filter (21). The regeneration device (22) is configured to carry out two processes: an automatic regeneration process in which regeneration is carried out automatically, i.e., not on the basis of intervention by the operator; and a manual regeneration process in which the operator is requested to perform manual regeneration, and regeneration is carried out on the basis of intervention by the operator. As regards the automatic regeneration process, whether to perform regeneration or not is determined on the basis of the estimated collected amount (H) estimated from the engine rotation speed (N) and the fuel injection amount (F). As regards the manual regeneration process, whether to signal the operator or not is determined on the basis of the differential pressure (DeltaP) of the filter (21) for removing particulate matter.</p> |
