    • 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 adds capacitance at the second HV output, as compared to a direct mount. The secondary winding is shifted by a predetermined distance, relative to the primary winding, in direction toward the direct mount end of the ignition apparatus. The shifting reduces the internal load capacitance at the second end (top), so that when the capacitance added by the HV cable is considered, the respective load capacitances are balanced. The voltage variation between the two HV outputs is reduced.
    • 具有两个高压(HV)输出的双火花点火装置包含用于平衡每个HV输出上的负载电容的特征。 点火装置提供构造成直接安装在第一火花塞上的第一高压(HV)连接和用于通过HV电缆耦合到第二火花塞的第二HV连接。 与直接安装相比,HV电缆在第二HV输出端增加电容。 次级绕组相对于初级绕组在朝向点火装置的直接安装端的方向上偏移预定距离。 移位减小了第二端(顶部)的内部负载电容,因此当考虑到由HV电缆添加的电容时,相应的负载电容是平衡的。 两个HV输出之间的电压变化减小。
