ABSTRACT:
An ignition apparatus of a capacitor discharge ignition type comprises: an ignition timing signal generator to generate an ignition timing signal synchronized with the rotation of the engine; a capacitor; a blocking oscillator; a rectifier for rectifying the output voltage of the blocking oscillator and applying the rectified voltage to the capacitor thereby charging the capacitor; a switching device which is turned on in response to the ignition timing signal and discharges the stored charges of the capacitor, thereby generating a pulse voltage across the terminals of the primary winding of an ignition coil; and an ignition plug to generate a spark discharge by a high voltage generated in the secondary winding of the ignition coil. The blocking oscillator oscillates concurrently with the engine rotation. When the ignition timing signal is generated, the oscillation of the blocking oscillator is stopped in accordance with a phase of the output voltage of the AC generator. With this apparatus, a vain charging of the capacitor and a vain spark discharge can be prevented when the engine's rotation stops. The generation of a counter torque on the engine can be certainly prevented.
