摘要:
A ceramic sheathed-element glow plug includes a ceramic glow element made of an electrically conductive layer and an electrically insulating layer, in which the conductive layer is made of supply layers and a heating layer. The higher specific electrical resistance of the heating layer allows the temperature of the heating layer and of the combustion chamber to be determined, and the electrical contact between a connecting element and the glow element is established by a contacting element that is composed of a pellet made of an electrically conductive powder.

A ceramic sheathed-type glow plug, whose ceramic heating element is made of an electrically conductive conducting layer and an electrically insulating layer, is described. The conducting layer is made of lead layers and a heating layer. The higher specific electrical resistance of the heating layer allows the temperature of the heating layer and the combustion chamber to be determined. The electrical contact between a connector element and the heating element is established by a contacting element, which is in the form of a pellet made of an electrically conductive powder.

A sheathed-element glow plug for self-igniting internal combustion engines has an electrical heating element which projects into a combustion chamber of the internal combustion engine, and a current feed-through for providing a heating current for the heating element through an opening in the combustion chamber. A switch is positioned in the region of the current feed-through, and the heating current may be controlled by the opening and closing of the switch.

A device is proposed for monitoring the combustion process in internal combustion engines, a direct monitoring and a monitoring of individual combustion processes, in particular individual combustion chambers, being possible. This is achieved using a waveguide, which is integrated in a component, which protrudes into the combustion chamber.

A ceramic sheathed-element glow plug is proposed in which a metallic tubular holder holds a ceramic U-shaped heating device in a cantilevered fashion at its combustion chamber side end and has a terminal stud for applying a voltage to the ceramic heating device on the end remote from the combustion chamber. At its end enclosed by the holder, the ceramic heating device has a segment of greatest diameter and is coated with an insulating layer which has recesses for an electrical contacting. One recess is provided at the end of the ceramic heating device remote from the combustion chamber and a second recess is provided on the external wall of the ceramic heating device. A for an electrically conductive sealing compound is provided between the external wall of the ceramic heating device and the internal wall of the holder.
摘要:
A ceramic electric resistor is proposed which can be made by means of ceramizing at least one organo-silicon polymer and at least one filler. The filler comprises at least one high-melting electrically conductive component, with the filler portion amounting to 20 to 50 vol. % relative to the solvent-free polymer-filler mixture. The specific electrical resistance can be set by varying the filler portion. The ceramic electric resistor is particularly suited as heating conductor for pencil-type glow plugs.

A glow tube, in particular for a sheathed-element glow plug. The glow tube, which has a dome-shaped, closed end section (27) and a cylindrical, open end section (28), is composed of at least two axially serially disposed glow tube parts. The one glow tube part is formed at the closed end section (27) by a seamless glow tube cap (31), and the other glow tube part is formed at the open end section (28) by a substantially cylindrical glow tube extension (32).
