Abstract (en)
[origin: EP0657698A2] A current self-control type glow plug includes a ceramic pipe 2 attached to a hollow body 1 having a connector 12, and a front end portion 15 and a body-side end portion 17 of the pipe 2 are filled with ceramic fillers 6,7. The coil 3 comprises the heating coil part 4 and the control coil part 5. The heating coil part 4 constituting a heating part is arranged in contact with the inner wall surface 20 of the pipe 2. The control coil part 5 constituting a current control part is arranged out of contact with the inner wall surface 20 of the pipe 2. The current control means 10 having a positive resistance-temperature coefficient is connected to the coil 3 and the connector 12. The resistance of the current control means 10 sharply increases above a specified temperature to cut off the current supply to the coil 3. <IMAGE>
