火時期制御装置。[Claims for Utility Model Registration] An ignition timing control device for an internal combustion engine that can be used by switching or mixing different types of fuel, which detects the concentration of reference fuel in the fuel supplied to the engine. a reference fuel concentration detection means; a basic ignition timing setting means for setting a basic ignition timing based on at least the reference fuel concentration detected by the reference fuel concentration detection means; an engine temperature detection means for detecting engine temperature; Retard correction value setting means for setting a retard correction value for the basic ignition timing based on the engine temperature detected by the temperature detection means; and a retard correction value set by the retard correction value setting means for the reference fuel. a retard correction value correction means for correcting and setting based on the concentration; and a retard correction value for the basic ignition timing based on the retard correction value corrected and set by the retard correction value correction means to determine the final ignition timing. An ignition timing control device for an internal combustion engine, comprising: an ignition timing setting means for setting an ignition timing; and an ignition control means for controlling ignition based on the ignition timing set by the ignition timing setting means.
