Ignition apparatus for preventing unnecessary charging in an internal combustion engine
An ignition apparatus of a capacitive discharge type for use in an internal combustion engine is described, comprising: DC voltage generating means for generating a DC voltage; an AC generator having a rotor rotating with the rotation of the engine so as to generate as AC current; ignition timing signal generating means for generating an ignition timing signal synchronized with a rotation of the engine; an ignition coil; a capacitor; a blocking oscillator including a transformer; energizing means, responsive the the AC current, for energizing the switching element; a first rectifier for rectifying an output voltage from the ternary winding of the blocking oscillator; a switching device, for discharging the capacitor in response to the ignition timing signal, thereby generating a pulse voltage across terminals of a primary winding of the ignition coil; an ignition plug for generating a high voltage spark discharge across a spark gap; and stop control means, connected to the energizing means; the stop control means including, a half-wave rectifier for passing therethrough the pre-selected half-wave of the AC current, and switching means, responsive to the ignition timing signal and the pre-selected half-wave of the AC current, for preventing the energization of the switch element by the energizing means.
