Claims

[Scope of utility model registration request]

In an ignition timing control device having an operating state detection means for detecting the operating state of an internal combustion engine and an ignition control means for controlling ignition timing in cooperation with the operating state detection means, a signal representative of load fluctuation is output. Based on the load fluctuation detection means, the temperature detection means for detecting a temperature dependent on the combustion chamber wall temperature, and the signals from the load fluctuation detection means and the temperature detection means,
An ignition timing control device for an internal combustion engine, comprising an ignition timing correction means that advances the ignition timing by determining an ignition timing correction amount according to a combustion chamber wall temperature when the load increases.
