Abstract:
A fuel vaporizer for use in an internal combustion engine, comprising:housing means constructed of a material having high thermal conductivity and defining an interior chamber, the housing means further defining an inlet connected to a fuel injector at which a fuel is injected into the chamber, an air intake hole comprising a one-way air intake valve, and an outlet through which the fuel exits the chamber; heating means to heat at least one surface of the interior chamber sufficiently to boil the liquid fuel upon contact with the at least one surface, the heating means comprising at least one resistance heating element mounted exterior to the interior chamber and proximate to the at least one surface of the chamber, and, an electronic control means to control the temperature of the at least one resistance heating element, the electronic control means comprising a thermostatic temperature control connected to the heating means; and, pre-heating means disposed in a fuel line connected to the fuel injector, comprising a fuel line heater with an electronic temperature controller attached thereto and, a fuel vapor siphon tube extending from the outlet inwardly to a point proximate one of the heated surfaces located at the bottom of the interior chamber, to funnel the fuel vapor and any remaining un-vaporized fuel out of the interior chamber to the intake manifold.
