ABSTRACT:
A fuel preheater for an internal combustion engine is described including a hollow housing which is mounted within an insulated cover. The hollow housing is provided with a fuel inlet at its upper end which is in communication with the engine fuel pump. A valve member is vertically movably mounted in the fuel inlet and is adapted to close the fuel inlet at times. A fuel atomizer is provided on the lower end of the valve member for atomizing the fuel supplied thereto. A float is mounted within the housing and is operatively connected to the valve member for closing the valve member upon a predetermined level of fuel accumulating in the lower end of the housing. Insulated electrical leads extend through the housing below the fuel atomizer for heating the atomized fuel. The housing is provided with a fuel discharge which is in communication with the carburetor of the engine. An air inlet is provided at one end of the housing to permit heated air to pass therethrough. A spring loaded valve normally closes the air inlet but is opened by the vacuum present within the housing. The opposite ends of the housing are provided with spring loaded covers or plates which open the opposite ends of the housing upon a predetermined pressure being experienced within the housing.
