CONTROL DEVICE OF ENGINE

To provide a control device of an engine which can make compatible both the securement of engine torque and the prevention of the deterioration of the engine.SOLUTION: When a strong knock frequency being the number of times at which knock strength reaches second determination strength or higher which is higher than prescribed first determination strength is equal to or less than a determination frequency C1, and the knock strength is higher than the first determination strength, a control device of an engine performs first control for controlling output adjustment means 13 so that the knock strength is lowered, and when a strong knock frequency is higher than a determination frequency C1, the control device performs second control for controlling the output adjustment means 13 so that the maximum torque of the engine is lowered more than the case that the strong knock frequency is equal to the determination frequency C1 or lower.SELECTED DRAWING: Figure 11 【課題】エンジントルクの確保とエンジンの劣化防止とを両立することのできるエンジンの制御装置を提供する。【解決手段】ノック強度が所定の第１判定強度よりも大きい第２判定強度以上になった回数である強ノック回数が所定の判定回数Ｃ１以下で、且つ、前記ノック強度が前記第１判定強度よりも大きい場合、前記ノック強度が低下するように出力調整手段１３を制御する第１の制御を実施し、強ノック回数が前記判定回数Ｃ１よりも大きい場合、強ノック回数が判定回数Ｃ１以下のときよりもエンジンの最大トルクが低下するように出力調整手段１３を制御する第２の制御を実施する。【選択図】図１１
