Abstract
A suction heating device for an internal combustion engine including a first metal member having a planar portion and a cylindrical portion extending from the flat portion for defining a passage for a fuel-air mixture, and a second metal member having a planar portion and a cylindrical portion extending from the planar portion and arranged outside the cylindrical portion of the first metal member with a predetermined spacing. The two cylindrical portions are joined to each other at the end to provide a casing for mounting therein a ceramic heater of positive temperature coefficient characteristic having a specific Curie point.
