Abstract (en)
[origin: EP0902236A2] A glow plug used in diesel engines is provided which includes a plug housing, a heater casing, and a heating element. The heating element consists of a heating coil and a current-controlling coil connected in series with the heating coil to control the current flowing to the heating coil. The heater casing has disposed therein the heating coil and the current-controlling coil and is inserted partially into the housing from an open end thereof. The heater casing includes a small-diameter portion and a large-diameter portion connected in series with the small-diameter portion. The whole of the large-diameter portion is disposed within the housing in tight engagement therewith, while the whole of the small-diameter portion projects from the open end of the housing for producing a clearance with an inner wall of a glow plug mount hole formed in an engine head to minimize the heat transfer from the heating element to the engine head. <IMAGE>
