フ装置。 In a control device for an internal combustion engine that includes a fuel injection valve and a spark plug for each cylinder of a multi-cylinder internal combustion engine, an abnormality in each ignition means including the spark plug is detected for each spark plug, and an abnormality detection signal is output. In addition to providing an abnormality detection means for each fuel injection valve, the fuel injection system forcibly stops fuel injection from the fuel injection valve in response to an abnormality detection signal from the abnormality detection means corresponding to the ignition plug of the same cylinder. A fail-safe device for a control device for an internal combustion engine, characterized in that it is provided with a stopping means.
