Abstract
Official abstract text for this publication.
A method for controlling a corona ignition device, which comprises an ignition electrode, at which a corona discharge is produced, a resonating circuit, which contains the ignition electrode, and a high-frequency generator connected to the resonating circuit, wherein the resonating circuit is excited with an AC voltage (U i ) produced by the high-frequency generator, the frequency of said voltage being specified by a control signal (U d ) applied across the high-frequency generator, the frequency of the control signal (U d ) is changed as the control variable of a control circuit, and the phase position between the current (I i ) flowing in the resonating circuit and a voltage signal is regulated to a target value, characterised in that the target value is changed during the operation of the corona ignition device. A corona ignition device for igniting fuel in a combustion chamber of an internal combustion engine is also described.
First claim
Opening claim text (preview).
1 . A method for controlling a corona ignition device having an ignition electrode at which a corona discharge is produced, a resonating circuit containing the ignition electrode, and a high-frequency generator connected to the resonating circuit, the method comprising: exciting the resonating circuit with an AC voltage produced by the high-frequency generator, the frequency of said voltage being specified by a control signal applied to the high-frequency generator; changing the frequency of…
