摘要： An ignition timing adjusting system for an internal combustion engine wherein the output of a magneto-type generator driven by the engine is used as a power source to generate a constant voltage output through a voltage regulator circuit, and a rotational angular position of the engine is detected by a sensor and the corresponding output signal being used as a reference signal in order to electronically determine an ignition timing by an advance angle computing circuit energized by the constant voltage output of the voltage regulator circuit, and further detecting the constant voltage output of the regulator circuit, and an advance angle adjusting circuit cancels the computed output from the advance angle adjusting circuit when the detected voltage is less than a voltage which is an absolute minimum voltage necessary for the accurate ignition timing operation, whereby when the detected constant voltage output is not adequately regulated the computed output of the advance angle adjusting circuit causing the excessively advanced ignition timing is ignored, instead, forcibly timing the ignition to occur at the low-speed fixed angular position.
