Abstract

PURPOSE:To stabilize ignitions at the time of low revolution of an engine by inputting a signal of a fixed lead-angle characteristic based on the first signal coil and a signal corresponding to the number of revolutions based on the second signal coil leading the first one by a fixed angle into a semiconductor switching means. CONSTITUTION:A rectified voltage B of the second signal coil 4 leading the first signal coil 3 by a fixed angle in a magnetodyanmo 1 is inputted into an ignition timing control circuit 8 for obtaining an output voltage G at a time corresponding to the number of revolutions. This output voltage G and a rectified voltage H generated constantly at a required position of ignition without reference to the number of revolutions by the first signal coil 3 are commonly added to a gate 5b of a thyristor 5a in an ignition circuit 5 using the output of a generating coil 2 for an electric source. In this construction, at the time of low speed revolution under a fixed level with great changes in the number of revolutions, since the rectified voltage H by the first signal coil is generated earlier than the output voltage H, the time of ignition can be determined thereby to obtain a stalibized ignition time, and the lead-angle characteristic can be improved by means within the area of normal revolution.
