Abstract The method involves using a discharge at an electrode in a combustion chamber. The electrode has a discharge section with a shape suitable for producing an inhomogeneous field and is supplied with a high frequency ignition signal in the megahertz range whose voltage and frequency are adjusted depending on the shape of the discharge section so the discharge is formed between the electrode and a counter electrode in the combustion chamber. The method involves using a discharge at an electrode (1) arranged in a combustion chamber (9). The electrode has a discharge section (10) in the chamber with a shape suitable for producing an inhomogeneous field and is supplied with a high frequency ignition signal in the megahertz range. The voltage and frequency of the ignition signal are adjusted depending on the shape of the discharge section of the electrode so that the discharge is formed between the electrode and a counter electrode (2) in the combustion chamber. AN Independent claim is also included for the following: a high frequency ignition device for internal combustion engines and an internal combustion engine. Bei einer Verbrennungskraftmaschine soll innerhalb eines Brennraums (9) ein Kraftstoff-Luft-Gemisch (3) mittels Hochfrequenzzündung entzündet werden. Erfindungsgemäß wird dazu eine Entladung zwischen einer Elektrode (1) und einer Gegenelektrode (2) ausgebildet, wobei die Elektrode (1) eine Form aufweist, die zur Erzeugung von Feldstärkeüberhöhungen geeignet ist. Auf diese Weise wird das Entstehen einer Entladung begünstigt, so dass nur eine geringe Frequenz im Bereich von wenigen 100 kHz bis wenigen MHz erforderlich ist. Dadurch verringert sich der Aufwand für die zur Erzeugung der Entladung verwendete Hochspannungsquelle (7) und kann durch die gezielte Ausbildung der Entladung zwischen der Elektrode (1) und der Gegenelektrode (2) die Entladungsenergie in einem genau definierten Bereich innerhalb des Brennraums (9) eingebracht werden.
