Embodiment Construction

[0053] figure 1 Combustion chamber 1 delimited by grounded walls 2 , 3 and 4 is shown. The ignition electrode 5 protrudes upwards into the combustion chamber 1 and is surrounded over part of its length by an insulator 6 by means of which it penetrates the upper wall 2 into the combustion chamber 1 in an electrically insulated manner. The ignition electrode 5 and the walls 2 to 4 of the combustion chamber 1 are part of a series resonant circuit 7 which also contains a capacitor 8 and an inductor 9 . The series resonant circuit 7 may have further inductors and / or capacitors as well as other components, which are known to the person skilled in the art as possible components of a series resonant circuit.

[0054]A radio-frequency generator 10 is provided for exciting the resonant circuit 7 . The high-frequency generator 10 comprises a DC voltage supply 11 , and a transformer 12 with a center tap 13 on its primary side, whereby the two primary windings 14 and 15 join at the cente...

Abstract

The invention relates to a method for controlling a corona ignition device that has a high-frequency generator and a resonant circuit that contains an ignition electrode, wherein a primary voltage is fed into the high-frequency generator, the resonant circuit is excited by a secondary voltage generated by the high-frequency generator, and a corona discharge is thus produced at the ignition electrode, a series of values of an electric variable are measured during the excitation of the resonant circuit, it is checked, by evaluating the measured values, whether the corona discharge has transitioned into an arc discharge, and a determination of an arc discharge is responded to by reducing the secondary voltage and thus extinguishing the arc discharge.

Description

technical field [0001] The invention relates to a method for controlling a corona ignition device comprising a high-frequency generator and a resonant circuit comprising ignition electrodes. Background technique [0002] A corona ignition device is disclosed in WO 2010 / 011838, in which a fuel / air mixture in a combustion chamber of an internal combustion engine can be ignited by a corona discharge generated in the combustion chamber. The corona ignition device comprises an ignition electrode inserted into an insulator. The ignition electrode together with the insulator and the bushing surrounding the insulator form a capacitor. The capacitor is part of the electrical resonant circuit of the corona ignition device, which is excited by the high frequency AC voltage. As a result, an overvoltage is generated at the ignition electrode, so that a corona discharge forms at this electrode. [0003] Corona discharge should not be broken down into arc discharge or spark discharge. ...
