ABSTRACT:
A glow plug comprises a heating rod with an inner heater coil and optionally at least one control coil, the heating rod being insulated from the glow plug body and is provided with a plug-type or screw terminal for the power supply voltage. Furthermore, the terminal (4) has an electronic component (6), preferably a chip, with a terminal (7) connected to the power supply voltage, a terminal (8) connected to the glow tube (1.3) and a terminal (9) connected to the body (3). The electronic component (6) is designed as a control element for switching the functioning of the glow plug between a heating function and a sensing function for measuring the ion flow in the combustion space area in proximity to the heating rod (1).
