Estimating the term…
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).
A glow plug comprising a glow plug body, a glow tube, a heating rod with inner heater coil, the heating rod being insulated from the glow plug body, and a power terminal for connection to a power supply voltage source;
Plug-type terminal for a glow plug, comprising an electronic component with a terminal for connection to the power supply voltage, a terminal for connection to the glow tube and a terminal for connection to a body of the glow plug, wherein the electronic component is a control element for switching functions of the glow plug, in use, between a heating function and a sensing function for measuring ion flow in a combustion space area.
