Abstract
A twin spark ignition apparatus having two high-voltage (HV) outputs incorporates features for balancing load capacitance on each HV output. The ignition apparatus provides a first high-voltage (HV) connection configured for direct mounting on a first spark plug, and a second HV connection for coupling to a second spark plug by way of an HV cable. The HV cable would adds capacitance at the second HV output, as compared to a direct mount. Various structures are included to offset and balance the additional capacitance attributable to the HV cable so that the capacitance of the first HV connection and the second HV connection are balanced within a range. The voltage variation between the two HV outputs is reduced.
