Abstract

Glow plug for engine starting is of the sheathed element self-limiting type and has a sheath (20) enclosing the heating and resistance coils (26,28) which has a reduced diameter or other discontinuity (32) in its wall in an intermediate zone at or adjacent to the interconnection (30) between the coils in order to delay or resist conductive dispersion of heat from the tip portion (22) of the sheath containing the heating element to the remainder thereof.
