ABSTRACT:
A fuel heater is provided for internal combustion engines utilized on motorized vehicles and utilizing a fuel stored as a liquid. The fuel passes through a frusto-conically shaped coil within a heat exchanger wherein heat is transferred thereto from engine heated cooling fluid which enters the exchanger tangentially and exits axially therefrom. Flow of the fluid through the exchanger is controlled by the speed of the water pump and by an ambient temperature sensitive valve. Preferably, there is also a restriction device for the liquid which sets an initial temperature therein which temperature after setting is generally maintained by cooperation between the pump and the ambient temperature sensitive valve.
