ABSTRACT OF THE DISCLOSURE A fuel discharge apparatus for an internal combustion engine in which fuel in a quantity metered by a fuel metering device is continuously injected into an intake conduit leading to the engine under pressure from a fuel injection valve. An electrically heating element is provided for heating the fuel flowing through a discharge passage extending between the intake conduit and the fuel injection valve. The heating element is formed of a semiconductor ceramic material having a positive temperature coefficient of resistance exhibiting a critical temperature point beyond which the resistance of the heating element is changed abruptly so that the temperature of the heating element is maintained sub- stantially constant independently from variation in the temperature of fuel to be heated.
