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.

    【課題】粒子状物質の排出量が増大し易い環境で運転しても、再生頻度の増大に伴う燃費の低下を抑制することができるハイブリッド作業機械を提供する。【解決手段】ハイブリッド制御装置45は、排気ガス浄化装置29のフィルタ29Aに粒子状物質が一定量捕集されると、該フィルタ29Aを再生すべく、エンジン制御装置26にポスト噴射を行う旨の指令を出力する。これに加えて、ハイブリッド制御装置45は、エンジン21から排出される粒子状物質の排出量を外囲条件、より具体的には、気圧センサ27により検出される気圧および温度センサ25により検出される吸気温度に基づいて予測する。さらに、ハイブリッド制御装置45は、予測された予測排出量が予め定めた所定値を超えると、エンジン21の最低回転数を高くする。【選択図】図2
