ABSTRACT:
A fuel pre-heater including a compartment for receiving fuel, a hollow metal member passing centrally through the fuel space in the compartment and coupled to the liquid cooling system of an internal combustion engine for transferring heat to the fuel, a length of a hollow pipe of insulation plastic material disposed within the hollow metal member and for regulating and controlling water flow therethrough to a heat transfer surface of the hollow metal member so that the heat transferred therefrom is received by the fuel and the fuel, being thus pre-heated, passes to the engine. The hollow plastic pipe regulates the water flow and controls the rate of heat transfer through and around it by an arrangement of apertures therein. The plastic pipe may be of polyvinyl chloride. The compartment may have a bracket for mounting it securely upon a wall in the engine compartment of the vehicle.
