Abstract
A fuel injector system has a pair of half-cylindrical elements of a ceramic material of positive temperature coefficient resistivity held in nested relation with a nozzle tip of a fuel injector, preferably by an annular spring fitted over the elements, to serve as self-regulating electrical resistance heaters to heat the fuel injector to heat fuel passed through the nozzle tip to an internal combustion engine. A cup-shaped electrically insulating housing has an open end fitted over the spring and heater elements on the nozzle tip and has an aperture in the bottom of the housing cup through which fuel is sprayed to the engine.
