備したことを特徴とする内燃機関制御装置。[Claims for Utility Model Registration] An internal combustion engine control circuit that controls an internal combustion engine so as to stop the rotation of the internal combustion engine or limit the rotational speed of the internal combustion engine when a control command signal is given, and an internal combustion engine. An internal combustion engine control device comprising: an abnormality detector that detects an abnormality in the internal combustion engine; and a control command supply circuit that supplies the control command signal to the internal combustion engine control circuit when the abnormality detector detects an abnormality in the internal combustion engine. The control command supply circuit includes a rotation detection circuit that detects the rotation speed of the internal combustion engine and outputs a stable state detection signal when the detected speed exceeds a set value; a delay circuit that starts a timed operation when a state detection signal is generated and generates a control operation permission signal when the timed operation is completed, and detects the abnormality while the delay circuit is generating the control operation permission signal. and a command signal supply control circuit that supplies the control command signal to the internal combustion engine control circuit only when the internal combustion engine detects an abnormality in the internal combustion engine.
