摘要： A system and method for detecting arc formation in a corona discharge ignition system is provided. The system includes a driver circuit conveying energy oscillating at a resonant frequency; a corona igniter for receiving the energy and providing a corona discharge; and a frequency monitor for identifying a variation in an oscillation period of the resonant frequency, wherein the variation in the oscillation period indicates the onset of arc formation. The method includes supplying the energy to the driver circuit and to the corona igniter; obtaining the resonant frequency of the energy in the oscillating driver circuit; and identifying a variation in the oscillation period of the resonant frequency.

摘要： A corona ignition system for providing a corona discharge (24) includes an igniter (20) having an electrode (26) with an asymmetrical firing tip (28) relative to an electrode center axis (ae). The firing tip (28) includes a first surface area (A1) facing the fuel injector (42) which is greater than a second surface area (A2) facing a cylinder block (32). The first surface area (A1) presents a projection (60) having a sharp edge, and the second surface area (A2) presents a round outward surface (62). Accordingly, a radio frequency electric field emitted from the first surface area (A1) provides a robust corona discharge (24) in a flammable area at an outside edge (30) of the fuel spray. No electric field is emitted from the second surface area (A2), and no power arcing occurs between the second surface area (A2) and the cylinder block (32).

摘要： A system and method for controlling an arc formation in corona discharge ignition system is provided. The system includes a corona igniter for receiving energy at a voltage and providing a corona discharge. An energy supply providing the energy to the corona igniter at a voltage. The system also includes a corona controller for initiating a decrease in the voltage of the energy provided to the corona igniter in response to the onset of arc formation. The voltage is decreased until the arcing is depleted, and then the voltage is increased again to resume the corona discharge. Controlling the arc formation provides improved energy efficiency during operation of the corona discharge ignition system.

摘要： 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.
