An ignition distributor, for an internal combustion engine, comprising a conventional distributor body housing and a cap having a centrally disposed input terminal and peripherally disposed output terminals connected to the engine spark plugs. A rotor is mounted on the end of the distributor shaft, and a dielectric timing ring is concentrically disposed in the housing between the rotor and the cap peripheral terminals. The timing ring has a conductive segment for each terminal, and the angular positioning of the timing ring segments relative to their corresponding spark plug terminals determine the timing of the beginning of the sparking across the gap between the rotor end contact and the spark plug terminal, and consequently across the corresponding spark plug electrodes. The timing ring is supported by a plate which is angularly orientable by way of a conventional vacuum spark timing mechanism. The distributor input terminal is connected to a high voltage pulse generator, and the breaker points, cam, capacitor and ignition coil, generally associated with conventional ignition systems, are omitted.
