To suppress a discharge amount of harmful substances from increasing upon starting a stopped internal combustion engine.SOLUTION: A controller of an internal combustion engine is configured to, when fuel is combusted in a cylinder of the internal combustion engine to finish firing for operating the internal combustion engine and the rotation of the internal combustion engine is then stopped, variably adjust a time required for the internal combustion engine to stop rotating, according to an engine speed at the end of the firing and the output signal of the air-fuel ratio sensor downstream of the exhaust gas purification catalyst mounted in an exhaust passage.SELECTED DRAWING: Figure 4

    【課題】停止していた内燃機関を始動する際の有害物質の排出増を抑制する。【解決手段】内燃機関の気筒において燃料を燃焼させて内燃機関を運転するファイアリングを終了して内燃機関の回転を停止させるにあたり、その内燃機関の回転が停止するまでの所要時間を、ファイアリングを終了するときの回転数及び排気通路に装着した排気浄化用の触媒の下流の空燃比センサの出力信号に応じて可変調整する、内燃機関の制御装置を構成した。【選択図】図4
