Claims

[Scope of Claim for Utility Model Registration] a. An operating state detection means for detecting the operating state of the engine, and b. An intake device that is provided in the intake passage of the engine and that opens and closes to narrow the intake passage to generate a vortex in the combustion chamber of the engine. an opening/closing state detection means for detecting the opening/closing state of the control valve; c. an opening estimation means for estimating the opening of the intake control valve based on the opening/closing state of the intake control valve; d) a basic detection means based on the output of the opening estimation means. a correction amount calculation means for calculating a correction amount for correcting the ignition timing; e. an ignition timing setting means for setting a basic ignition timing based on the operating state of the engine and correcting the basic ignition timing according to the correction amount; , f An ignition timing control device for an internal combustion engine, comprising: ignition means for igniting the air-fuel mixture based on the ignition timing setting means;
