A high-frequency ignition system for spark ignition engines has a large ignition range with a cover measuring up to a plurality of square centimeters and enables the optional adjustment of the duration of the ignition. The combustion time can be minimized as a result of the large ignition range. Excellent degrees of efficacy can be obtained with this ignition using dielectric electrodes. The high-frequency ignition system can be very economically produced by means of high-frequency electronic components which are available at a very low cost as a result of the telecommunication market, and by means of standard spark plug technology. The high-voltage requirements are also significantly lower compared to classic ignition systems.
