Claims

[Claims for Utility Model Registration] (1) A signal coil that generates positive and negative signals in synchronization with the rotation of the engine, which is discharged at a constant time constant by a signal of one polarity of this signal coil, and which is a comparator. a constant angle oscillation circuit having a capacitor that is charged at a constant time constant when the terminal voltage drops to a first reference voltage;
an ignition timing calculation circuit comprising means for outputting an ignition signal by comparing the reference voltage with a reference voltage of the engine, and outputting an ignition signal according to the engine speed based on the output voltage of the constant angle oscillation circuit that changes with the engine speed. In an ignition timing control device that sets the ignition timing, the ignition timing according to the rotation speed is determined by the output voltage of a throttle sensor that is linked to the throttle opening of the engine and outputs a voltage corresponding to the throttle opening. An ignition timing control device characterized in that it is configured to change the ignition timing according to the timing. (2) The ignition timing control device according to claim 1, wherein the first reference voltage is controlled by the output voltage of the throttle sensor. (3) The ignition timing control device according to claim 1, wherein the second reference voltage is controlled by the output voltage of the throttle sensor. (4) The ignition timing according to claim 1 of the utility model registration claim, characterized in that the waveform of constant angle oscillation is controlled by controlling the amount of charge or discharge of the capacitor based on the output voltage of the throttle sensor. Control device.
