INTERNAL COMBUSTION ENGINE CONTROL DEVICE

PROBLEM TO BE SOLVED: To provide an internal combustion engine control device capable of detecting a combustion state in a combustion chamber and controlling the operating condition of an internal combustion engine according to the combustion state in a simple configuration.SOLUTION: An internal combustion engine control device 100 includes a control part 106b for controlling the injection amount of fuel so that a first temperature TCCTQ and a second temperature TCCTI correspond to each other according to a difference between the first temperature TCCTQ corresponding to the first assumed wall surface temperature of a combustion chamber 9 of an internal combustion engine 1, calculated from the instantaneous torque of the internal combustion engine 1, and the second temperature TCCTI corresponding to the second assumed wall surface temperature of the combustion chamber 9 of the internal combustion engine 1, calculated from the injection amount of the fuel for the internal combustion engine 1.SELECTED DRAWING: Figure 1 【課題】簡便な構成で、燃焼室内の燃焼状態を検出しその燃焼状態に応じて内燃機関の運転状態を制御可能な内燃機関制御装置を提供する。【解決手段】内燃機関制御装置１００では、制御部１０６ｂが、内燃機関１の瞬時トルクから算出した内燃機関１の燃焼室９の第１の想定壁表面温度に対応した第１の温度ＴＣＣＴＱと内燃機関１の燃料の噴射量から算出した内燃機関１の燃焼室９の第２の想定壁表面温度に対応した第２の温度ＴＣＣＴＩとの差分に応じて、第１の温度ＴＣＣＴＱと第２の温度ＴＣＣＴＩとが一致するように燃料の噴射量を制御する。【選択図】図１
