Abstract
An improved glow plug (10) which is adapted to be continuously electrically heated to a preselected elevated temperature in order to ignite relatively lower-cetane-number alternative fuels. The glow plug (10) includes a ceramic surface ignition element (20) disposed substantially externally of the glow plug body (18) and means (24) for permitting thermal expansion and contraction of the ignition element (20) while maintaining continuous electrically-conductable and gas-impermeable contact between the ignition element (20) and the glow plug body (18).
