Abstract (en)

The device has a heating element arranged in a glow tube on the combustion chamber side, whereby the glow tube is mounted in a plug housing and insulated from it. The plug housing is electrically connected to the engine block (earth). A diode (15) is integrated between the glow plug body (4) and the series circuit containing the flow tube and heating element in the connector area of the plug or a modular diode is used. An Independent claim is also included for a controller and for an arrangement for producing a glow discharge and/or for ion current measurement.
