Abstract
A method for setting adjusting frequency of an electric oscillating circuit of a corona ignition device. The circuit is excited with a starting value (f1) of the excitation frequency and a reference value (I) of a frequency-dependent variable is measured. The excitation frequency is incrementally changed. After every increment a value (I) of the frequency-dependent variable is measured and it is determined whether the measured value (I) deviates significantly from the reference value (I). Depending upon the measured value (I) relative to the reference value, the value (f) of the excitation frequency is either set as the new starting value (f1) or stored as a boundary value. Further incremental changes to the excitation frequency are made in one of two directions and further comparisons of the values I and Iare performed. Ultimately, the excitation frequency can be set to a mean value between first and second boundary values.
