    • An ignition system for igniting fuel within an engine, comprising at least one ignition plug disposed in the engine, wherein the ignition plug has a pair of electrodes. A high voltage generator is connected to the ignition plug for applying a gated high voltage high frequency AC signal across the pair of electrodes so as to initiate ionization of the air/fuel mixture and create an infant plasma channel between the pair of electrodes. A plasma arc current generator is connected to the ignition plug for generating a predetermined magnitude of alternating current for a predetermined period of time so as to sustain the plasma channel and ignite the fuel, and a controller is provided for selectively enabling and disabling the high voltage generator and the plasma arc current generator at predetermined times.
    • 一种用于点燃发动机内的燃料的点火系统,包括设置在发动机中的至少一个火花塞,其中火花塞具有一对电极。 高压发生器连接到火花塞,用于在一对电极之间施加门控高压高频AC信号,以便启动空气/燃料混合物的电离,并在该对电极之间产生婴儿等离子体通道。 等离子弧电流发生器连接到火花塞,用于在预定时间段内产生预定量的交流电流,以维持等离子体通道并点燃燃料,并且提供控制器用于选择性地启用和禁用高电压 发电机和等离子弧电流发生器。
