Abstract
A rod-type flame glow plug, with a glow tube (5), an inner pole (7), a coil combination having at least one control and glow coil (4) located in series with an ignition coil (3.2) in the glow tube (5), the ignition coil (3.2) being located at the tip of glow tube (5), making in contact with the glow tube, avoids problems associated with nonuniform centering of the coils in the glow tube by the coil combination being located predominantly within a tubular component (1) made of a heat-resistant material. The inner surface of the tubular component (1) adjoins the coil combination, and the outer surface of the tubular component (1) adjoining the inner surface of glow plug (5).
