Abstract
An ion flow measurement glow plug with an electrical terminal for the ignition current of a heating element which is located in a glow tube on an end which is directed to the combustion space of an engine block. The glow tube is located in a plug housing, insulated relative to the latter, and the plug housing is electrically connected to the engine block. At a terminal-side area of the plug, a solid-state switch is integrated or modulalry arranged, which is triggered by a control signal, as a result of which the second terminal of the heating element is switched to the engine block (ground) via the plug housing.
Claims7
Ion flow measurement glow plug with an electrical terminal for receiving glow plug current for a beating element which is located in a glow tube on an end directed toward a combustion space of an engine block in use, the glow tube being located in a plug housing, insulated relative to the plug housing, and the plug housing, in use, being electrically connected to ground;
- wherein a solid-state switch is integrated into a terminal end area of the plug, the switch being triggerable by a control signal and switching a ground terminal of the heating element, via the plug housing, to ground.
Control device for triggering at least one glow plug with an electrical terminal for receiving glow plug current for a heating element which is located in a glow tube on an end directed toward a combustion space of an engine block in use, the glow tube being located in a plug housing, insulated relative to the plug housing, and the plug housing, in use, being electrically connected to ground;
- wherein a solid-state switch is arranged at a terminal end area of the plug, the switch being triggerable by a control signal from the control device and switching a second terminal of the heating element, via the plug housing, to ground in response thereto.
Arrangement for glow plug current and ion flow measurement, comprising a control device and at least one glow plug with an electrical terminal for receiving glow plug current for a heating element which is located in a glow tube on an end directed toward a combustion space of an engine block in use, the glow tube being located in a plug housing, insulated relative to the plug housing, and the plug housing, in use, being electrically connected to ground;
- wherein a solid-state switch is arranged at terminal end area of the plug, the switch being triggerable by a control signal the control device and switching a second terminal of the heating element, via the plug housing, to ground in response thereto.
