Abstract (en)

A distributorless ignition system utilizes a capacitor discharge arrangement wherein the capacitor (15) is charged by voltage pulses derived from an inverter (14) through an ignition transformer (10). The capacitor (15) which is located in the secondary circuit of the transformer (10) is discharged by a controlled switching device (16) also located in the secondary circuit.
