Abstract (en)
[origin: WO2017167437A1] The invention relates to an ignition device (10) for igniting an air-fuel mixture in a combustion chamber, in particular an internal combustion engine, having a spark plug (12), which has a first electrode (18) and a second electrode (19), and a high voltage source (14) for generating an electrical high voltage impulse on an output (22) of the high voltage source and having a high frequency voltage source (16) for generating an electrical high frequency alternating voltage on an output (26) of the high frequency voltage source (16), wherein the output (22) of the high voltage source (14) is electrically connected to the first electrode (18) of the spark plug (12) via a first electrical conductor path (24) such that the high voltage impulse is applied to the first electrode (18), wherein the second electrode (19) is connected to an electrical ground potential, wherein the spark plug (12) has a third electrode (20), wherein the output (26) of the high frequency voltage source (16) is electrically connected to the third electrode (20) via a second electrical conductor path (28), such that the high frequency alternating voltage is applied to the third electrode (20).
