An arrangement transmits a torque between a shaft and a hub. The hub has at least approximately the interior geometry of an equilateral n-sided polygon, the side surfaces of which at least approximately bear against a clutch portion, which is of circular overall cross section, of the shaft, and wherein the shaft has at least one driver portion which is rotationally conjoint with respect to the clutch portion and which extends in the direction of a corner of the n-sided polygon.

Arrangement for transmitting a torque between a shaft and a hub

A sheathed element glow plug having an ionic current sensor and a method of operating such a sheathed element glow plug are provided. The sheathed element glow plug includes a housing and a rod-shaped heating element arranged in a concentric bore in the housing. The heating element has at least one insulation layer, a first feeder layer, and a second feeder layer, the first feeder layer and the second feeder layer being connected by a web on the combustion chamber-side end of the heating element, the first and second feeder layers and the web being made of an electrically conducting ceramic material, and the insulation layer being made of an electrically insulating ceramic material. The heating element has at least one ionic current detection electrode made of an electrically conducting ceramic material.

Sheath type glowplug with ion current sensor and method for operation thereof

A sheathed-element glow plug having an ionic-current sensor, as well as a method for operating a sheathed-element glow plug having an ionic-current sensor are described, the sheathed-element glow plug having a housing and a rod-shaped heating element arranged in a concentric bore hole of the housing. The heating element has at least one insulating layer as well as a first lead layer and a second lead layer, the first lead layer and the second lead layer being connected via a bar at the end of the heating element on the combustion chamber side, the first and second lead layers and the bar being made of electroconductive ceramic material, and the insulating layer being made of electrically insulating ceramic material. The heating element has a first electrode for detecting ionic current and a second electrode for detecting ionic current which are embedded in the insulating layer or applied on the insulating layer.

Sheath type glow plug with ion current sensor and method for operation thereof

A sheathed-type glow plug is provided, for example, for starting a self-igniting combustion engine, including a heating pin engaging in a combustion chamber having an ignitable fuel-air mixture, which includes an electrically conductive ceramic, and which may be heated to an ignition temperature by being connected to a voltage source, the sheathed-type glow plug surrounding an integrated temperature sensor.
