ABSTRACT:
A contactless ignition system for an internal combustion engine including an ignition signal generator having two pickup coils which are connected in series or parallel and oppositely in polarity to each other so as to be responsive to the rotation of a signal rotor in order to generate respective AC signals with one signal occurring at an intermediate position of the other, an input circuit disposed so as to be turned on or off when the AC signal from the ignition signal generator exceeds predetermined values in the positive and negative directions, respectively, an inverter circuit disposed to invert the output of the input circuit, first and second output circuits for generating a first output to turn on or off responsive to the output of the input circuit and a second output to turn off or on responsive to the output of the inverter circuit, and first and second ignition coils respectively responsive to the first and second outputs each so as to switch on and off the primary current therethrough.
