具有选择性增强电弧形成的电晕点火系统

Corona ignition system having selective enhanced arc formation
Abstract:
A corona discharge (24) ignition includes an electrode (38) emitting a radio frequency electric field and providing a corona discharge (24) to ignite a combustible mixture. The system includes a controlled high voltage energy supply (52) providing energy to a main energy storage (28) at a main voltage. A fixed high voltage energy supply (54) provides extra energy to an extra energy storage (26) at an extra voltage, which is greater than the main voltage. While the corona discharge (24) is being provided, the energy of the main energy storage (28), but not the extra energy storage (26), is provided to the electrode (38). When the corona discharge (24) switches to arc discharge, the extra energy of the extra energy storage (26) is provided to the corona igniter (22) to enhance the arc discharge and provide reliable ignition until the corona discharge (24) is restored.
Abstract(Chinese):

电晕放电（24）点火包括发射射频电场的电极（38），并提供电晕放电（24）来点燃可燃混合物。 该系统包括在主电压下向主能量存储器（28）提供能量的受控高压能量供应（52）。 固定的高压能量源（54）在额外的电压（大于主电压）的情况下向额外的能量存储器（26）提供额外的能量。 当提供电晕放电（24）时，主电能存储器（28）的能量而不是额外的能量存储器（26）的能量被提供给电极（38）。 当电晕放电（24）切换到电弧放电时，额外的能量存储器（26）的额外能量被提供给电晕点火器（22），以增强电弧放电并提供可靠的点火，直到电晕放电（24）被恢复 。
