Abstract: A self-regulating heater for use in an early fuel evaporation system for an automotive engine includes a metallic radiator having a first heat-receiving side and an opposite side for transferring heat to a fuel evaporization zone. Self-regulating ceramic electrical resistance heater elements having a positive temperature coefficient of resistivity(PTC) are disposed with first sides in facing relation with respective recessed first portions of the heat-receiving side of the radiator. A thermally conducting metal heat-transfer member has recessed first portions disposed in facing relation to respective second sides of the heater elements to receive heat second sides of the heater elements to receive heat from the second sides of the heaters and also has second portions disposed in closely-spaced facing relation to corresponding second portions of the heat-receiving side of the radiator, thereby to transfer the heat received from the second heater sides to the radiator.
