The invention discloses a capacitor ignition system for an internal-combustion engine of the type which basically includes a direct voltage converter and, having a control circuit coupled therewith for cyclically charging a storage capacitor, a switch-through circuit for discharging the capacitor in dependence on the firing order and a firing circuit to which the discharge voltage is fed for generating the ignition voltage for the spark plugs, wherein: a first storage capacitor essentially for storing the firing energy required to ionize the ignition spark path and a second storage capacitor essentially for storing the firing energy required to assure a period of dwell for the ignition spark are connected to the output of the direct voltage converter for charging by same and discharging via the switch-through circuit; the control circuit regulates the operation of the direct voltage converter, and includes a series-RC circuit for delaying the switching on of the direct voltage converter for a period of time after the capacitors are discharged and the circuit components for charging the capacitors are dimensioned so that the frequency of charging is independent of the ignition order frequency of the breaker points of the firing circuit.
