A pressure glow plug for a diesel engine has a glow plug bodyfor being inserted into a cylinder of the diesel engine, a heating rodthat is arranged in the glow plug bodyand a pressure sensorthat is arranged between the heating rodand the glow plug bodyin such a way that the pressure in the combustion chamber of the cylinder that is transmitted by the heating rodinfluences the pressure sensor. The heating rodis arranged in the glow plug bodysuch that it can be displaced in an axially sliding fashion, namely by a corresponding sliding element, for example, a membraneor seals

Pressure glow plug for a diesel engine

A pressure-measuring glow plug for a diesel engine with a plug body () for insertion into a cylinder of the diesel engine, a heating rod () which is arranged in the plug body (), and a pressure sensor, which is arranged under an initial tension between the heating rod () and the plug body (), in such a way that the pressure sensor () is acted upon by the pressure prevailing in the combustion chamber of the cylinder. The heating rod () transmits the pressure in the combustion chamber of the cylinder to the pressure sensor () and is arranged so as to be displaceable in a sliding manner in the axial direction relative to the plug body (). A seal in the form of a bellows-shaped component () is provided between the heating rod () and the plug body ().

Pressure-measuring glow plug

A glow plug including a heating rod having a plug body composed of an electrically insulating plastic material, an inner pole connected to heating elements, and optionally, control elements, and an outer pole which is electrically insulated from adjoining components of the plug body by an insulative material provided between an inner and outer support tube, the inner support tube surrounding the heating rod while the plug body surrounds the outer support tube.
