PROBLEM TO BE SOLVED: To provide a hybrid working machine which can suppress the lowering of fuel economy accompanied by an increase of a regeneration frequency even if the working machine is operated under an environment in which a discharge amount of particular substances is liable to increase.SOLUTION: When particular substances are collected in a filter 29A of an exhaust gas purification device 29 at a constant amount, a hybrid control device 45 outputs a command to an engine control device 26 indicating that post-injection is performed in order to regenerate the filter 29A. In addition to this, the hybrid control device 45 predicts a discharge amount of the particular substances discharged from the engine 21 on the basis of a surrounding condition, more concretely, on the basis of atmospheric pressure which is detected by an atmospheric pressure sensor 27 and an intake air temperature which is detected by a temperature sensor 25. Furthermore, when the predicted prediction discharge amount exceeds a prescribed value, the hybrid control device 45 increases the minimum rotation number of the engine 21. |
