摘要： The invention relates to a method for energizing an HF resonant circuit which contains an igniter as a component for igniting a fuel-air mixture in a combustion chamber of an internal combustion engine by means of a corona discharge, wherein the igniter comprises an ignition electrode and an insulator surrounding the ignition electrode, by means of a DC-AC inverter which is excited by successive current pulses which each last while a switch controlled by a control circuit is in its conducting switching state. It is provided according to the invention that the switch is actuated when an instantaneous value of an alternating current or an alternating current voltage excited in the HF resonant circuit falls below a first switching threshold (A−, B−, C−) and the switch s actuated when the instantaneous value of the alternating current or the alternating current voltage excited in the HF resonant circuit exceeds a second switching threshold (A+, B+, C+).

摘要： Described is an igniter comprising an arrangement composed of an ignition electrode, an outer conductor coaxially enclosing the ignition electrode, and an electric insulator disposed between the ignition electrode and the outer conductor, via which insulator the ignition electrode and the outer conductor are interconnected, for igniting a fuel/air mixture in a combustion chamber, in particular in an internal combustion engine comprising one or more combustion chambers which are delimited by walls that are at ground potential, by creating a corona discharge in an area surrounding the tip of the ignition electrode. According to the invention, the ratio of the outer diameter d of the ignition electrode and the inner diameter D of the outer conductor is in the range of 0.3 to 0.44.

摘要： Herein is described a method for the heating-up of a ceramic glow plug by applying a variable electric voltage to the glow plug. In accordance with the invention it is provided that, starting from a base value, the electric voltage increases in a time-averaged manner superproportional to the elapsed heating-up time. The invention relates also to a glow plug control unit for carrying out of such a method.
