This patent describes an internal combustion engine including a fuel feed and vaporization system, the system having a fuel tank containing a liquid fuel supply, a supply and return fuel line connected to the fuel tank. The improvement described here includes: an apparatus for providing a predetermined and preset quantity of preheated fuel and air to the combustion chamber, the supply line extending between the fuel tank and the apparatus, and the return line connected at one end to the supply line and at the other end to the fuel tank, at least two fuel pumps positioned in the supply line for pumping liquid fuel to the apparatus, at least one atomizer positioned in the supply line between the pump and apparatus for atomizing the fuel prior to its admission to the apparatus, the atomizer including multiple holes for passing the fuel through in order to atomize the fuel, a first predetermined and preset electric flow meter valve positioned in the fuel supply line between the two pumps and upstream of where the return line connects to the supply line to return an unused portion of the fuel from the supply line to the fuel tank, the apparatus including a housing containing at least three electric heat exchangers, an intake opening connected with the fuel supply line, the fuel passing in heat exchange relationship with some of the electric heat exchangers, an air intake opening into the housing, the air passing through a portion of the housing separate from the fuel and in heat exchange relationship with at least one of the electric heat exchangers prior to its mixing with fuel and being fed to an outlet in the housing which connects to the intake manifold of the internal combustion engine.
