A glow plug, in particular for use in an internal combustion engine. The glow plug includes at least one heating body and at least one housing. The heating body has at least one first terminal contact extending from a base body of the heating body into a housing. The glow plug also has a second terminal contact extending at least partially within the housing. At least one contacting element having at least one opening is provided inside the housing, the first terminal contact and the second terminal contact being introduced into the opening from opposite sides and being electrically connected.

Glow plug for use in an internal combustion engine

The present invention relates to a sheathed-element glow plug () for an internal combustion engine, essentially made up of a plug shell () and a glow element () that is electrically connected to the plug shell (), as well as an integrated pressure sensor. The sheathed-element glow plug () has at least one elastic element () that is situated between the inner surface () of the plug shell () and the glow element (), this element forming an electrical contact both to a part of the inner surface () of the plug shell () and to a part of the glow element surface (), and this element being deformable when a force acts on the glow element (), and this element permitting a relative movement between the glow element () and the shell ().

Sheathed-element glow plug having an elastically mounted glow element

A sheathed-element glow plug for an internal combustion engine, in which the sheathed-element glow plug is arranged or constructed so that it substantially reduces the glow temperature during the heat-up process. The control filament is considerably shortened and has a resistance between 20 m&#x3a9; and 100 m&#x3a9;.

Sheated-element grow plug having a substantially shortened control filament

A sheathed-element glow plug, in particular for internal combustion engines, includes a housing, a glow plug situated on the housing and having a heating and regulating filament situated in the glow tube, current being applicable to this heating and regulating filament via a terminal stud situated in the housing. The control filament r the heating filament or the heating and control filament are optionally multiple-coil filaments.

Multiple filament for sheathed-element glow plugs

A pin heater in a sheathed-element glow plug and a sheathed-element glow plug for internal combustion engines, which have improved electrical and mechanical properties, are described. The pin heater has at least one essentially internal insulating layer and one essentially external first conductive layer, both layers including ceramic composite structures. The pin heater includes a second conductive layer, which also includes a ceramic composite structure. The second conductive layer is bonded to the first conductive layer in the region of a combustion chamber side tip of the pin heater. The second conductive layer runs inside the insulating layer.

Plug heater for a pencil-type glow plug and corresponding glow plug

An electrically heatable glow plug and a method for manufacturing an electrically heatable glow plug are proposed that enable a protection of a heating coil of the glow plug against nitridation and evaporation of the aluminum from the heating conductor alloy. The glow plug includes a glow tube that is closed at the end, into which the electrically conductive heating coil is inserted, the heating coil being formed at least partially of aluminum, in particular of an aluminun-iron-chromium alloy. In the glow tube, oxygen donors are provided in order to form an aluminum oxide layer on the surface of the heating coil before or during the heating of the heating coil.

Electrically heatable glow plug and method for producing said electrically heatable glow plug

A sheathed-element glow plug to be mounted in a combustion chamber is proposed, a rod-shaped heating element being situated in a concentric bore hole of the housing. The heating element has a first current-carrying layer, a second current-carrying layer, and an insulating layer, the insulating layer separating the first current-carrying layer and the second current-carrying layer. The first current-carrying layer and the second current-carrying layer being connected at the end of the heating element on the combustion chamber side by a conducting-layer crosspiece. The first current-carrying layer and the second current-carrying layer are different lengths, the cross section of the first current-carrying layer in a first section at the end of the heating element away from the combustion chamber being greater than the cross section of its remaining length, and the second current-carrying layer not extending into the first section.

Sheathed-element glow plug

A sheath heater in a sheathed-type glow plug for diesel engines is described, having at least one generally internal insulation layer and at least one generally external conductive layer, both layers making up a ceramic composite structure. The sheath heater has a generally uniform overall cross-section, generally over its entire length, and, in the area of a tip of the sheath heater, the proportion of the insulation layer in the overall cross-section increases, whereas the proportion of the conductive layer in the overall cross-section decreases.

Sheath heater

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.
