Abstract
A fuel evaporator for an internal combustion engine, which is provided with a ceramic heater, is disclosed. The fuel evaporator comprises a plurality of layered thin PTC ceramic plates, each of which has a plurality of open holes, electrodes which are provided on an upper surface, an under surface and between adjacent ceramic plates, and an insulator for securing the outer periphery of the layered PTC ceramic plates to the wall defining an air-fuel passage of an engine. The ceramic plates are electrically connected to one another in parallel so that each ceramic plate is rapidly heated by consuming only a small amount of electric power.
