Abstract: The invention provides a system and method for controlling corona discharge. A driver circuit provides energy to the corona igniter and detects any arc formation. Optionally, in response to each arc formation, the energy provided to the corona igniter is shut off for a short time to dissipate the arc. Once the arc dissipates, the energy is applied again to restore the corona discharge. The driver circuit obtains information relating to the corona discharge, such as timing and number of arc formations. A control unit adjusts the energy provided to the corona igniter, shut-off time, or the duration of the corona event based on the information. The adjusted energy levels and duration are applied during subsequent corona events. For example, the voltage level could be reduced or the shutoff time could be increased to limit arc formations and increase the size of the corona discharge during the subsequent corona events.

Abstract: A corona discharge ignition system comprising a plurality of corona igniters is provided. The system includes a control and drive electronics unit for directing the energy from a power supply toward the corona igniters; and a single transformer disposed between the control and drive electronics unit and the plurality of corona igniters. A plurality of igniter switching units is connected to the control and drive electronics unit and each igniter switching unit is connected to a separate one of the corona igniters. Each igniter switching unit allows current to travel from the transformer to the one connected corona igniter when activated and prevents current from traveling from the transformer to the one connected corona igniter and from the one connected corona igniter toward the transformer when deactivated. Only one of the igniter switching units is activated at any given time during operation of the system.

Abstract: A spark plug includes a metallic shell, an insulator, a center electrode, a ground electrode, and a thin firing pad. The thin firing pad is made from a noble metal and can be attached to the center electrode, the ground electrode, or to both.
