Abstract
1. Glow plug for internal-combustion engine with applied ignition, with a heater (11) which can be fitted tightly into the cylinder of the internal-combustion engine, is surrounded by a tubular metal casing (13) and has a tubular, electrically insulating ceramic carrier (20) which is provided with a base on the combustion chamber side and is for a conductor track-like electrical heating element (37), which is arranged on the outer surface of the ceramic carrier (20), is connected via conductor track-like connecting conductors (38, 39) to the end section of the ceramic carrier (20) on the connection side and is covered by a dense, electrically insulating protective layer (40), the connecting conductors of the heating element (37) being in electrical connection with additional means of connection which can be connected to a power source, characterized in that a metal core is arranged in the section of the longitudinal bore (30) of the ceramic carrier (20) on the combustion chamber side as a heat sink (46), which metal core, on account of its expansion behaviour owing to temperature effect, is in contact over a considerable part of its surface with the ceramic carrier (20, 34) at operating temperatures above about 850/950 degrees C, but below the said operating temperature has at least partially a gap (47) with respect to the ceramic carrier (30, 34).
