In order to ignite fuel/air mixtures in at least one combustion chamber of a spark ignition engine, the following steps arc carried out: an HF gas discharge as the main discharge ( 6 ) is ignited in order to produce a plasma channel ( 11 ) in the region of the border between an ignition element and the combustion chamber, and an HF gas discharge as an auxiliary discharge ( 5 ) is previously or, at the most, simultaneously ignited in order to generate a flow ( 12 ) oriented towards that of the plasma channel ( 11 ). The auxiliary discharge ( 5 ) is positioned, from the combustion chamber, behind the main discharge ( 6 ), such that the oriented flow ( 12 ) presses the plasma channel ( 11 ) of the main discharge into the combustion chamber.
