The invention relates to a method for igniting a fuel/air mixture in one or more combustion chambers which are delimited by walls that are at ground potential, wherein an electric resonant circuit is excited in which an ignition electrode, which is guided through one of the walls delimiting the combustion chamber in an electrically insulated manner and which extends into the combustion chamber, in cooperation with the walls of the combustion chamber that are at ground potential constitutes a capacitance, and in which the excitation of the resonant circuit is controlled such that a corona discharge igniting the fuel/air mixture is created in the combustion chamber at the ignition electrode. The strength of the AC current flowing in the resonant circuit, the AC voltage exciting the resonant circuit and/or the impedance of the resonant circuit are monitored, and the observations or one or more measurement variables derived therefrom and/or the time curve thereof are used to obtain indicators that characterize the state of the combustion chamber and/or the state of the material mixture present in the combustion chamber and are provided for further processing.

A method and device for operation of glow plugs of a Diesel engine in which the type of glow plugs used is determined, by a parameter typical of the glow plugs, for example, the electrical glow plug resistance, being detected and evaluated. The detected values of the parameter typical of the glow plugs are compared with corresponding data for various types of glow plugs stored in the glow controller to determine the type(s) of glow plug(s) in the engine. After identification of the type(s) of glow plug(s), stored sets of parameters, which correspond to the type(s) of glow plug(s) determined, are likewise called upon to control the glow plugs.

Method and device for manufacturing a noble meal reinforced electrode for a spark plug. A base electrode element () is formed and positioned in a retaining attachment (). A noble metal piece () is arranged by a suitable attachment () on the front side of the base electrode element (), and pressed into the front side of the noble metal base element () by a press attachment, in particular a die (), while the arrangement composed of the base electrode element () and noble metal piece () is preferably heated by an electric current. After cooling, subsequent pressing can be carried out, by which the noble metal piece () is pressed flat. It is also possible to weld together the noble metal piece () and the tip () of the base electrode element.
