  • Fuel preheater for diesel engines
    Patent number: 4700047
    Abstract: A fuel preheating unit for diesel engines includes a heat exchange coil positioned in a fluid-tight enclosure having an inlet and outlet for a heat exchange medium, such as hot coolant or lubricant from the engine. The coil has a length of at least one foot for each 25 cubic inches of enclosure volume and has ends connected to a diesel fuel inlet and outlet on the enclosure. A spray tube connected to the heat exchange medium inlet extends horizontally below the entire length of the coil and has a plurality of upwardly directed openings for discharge of the heat exchange medium toward the coil for agitation of the medium in the enclosure around and over the coil. The enclosure is provided with an electric heater for heating the heat exchange medium during cold weather to assist in heating the fuel prior to the time the engine reaches operating temperature.
