ABSTRACT:
An auxiliary combustion chamber preheating device having a glow plug for a diesel engine with a metal shell threadedly mountable on the engine and a center electrode having a rod-like configuration. A tubular heat generating element having an opened end and a closed end is made of a nonmetalic resistance material selected from the group consisting of silicon carbide (SiC) or molybdenum disilicide (MoSi.sub.2) and inserted and is connected to the metal shell at the open end thereof. An electrical connection is established for electrically connecting a lower end surface of the center electrode and an inner wall portion of the closed end portion of the heat generating element. An electrical conductive layer is formed on an outer wall portion of the heat generating element.
