Abstract
A fuel vaporizer for internal combustion engines employs a chamber exposed to and directly below the underside of the engine carburetor and a heater wall at the bottom of the chamber to receive drops of fuel released from the engine carburetor into the intake manifold. It also includes an apertured wall having an upperside forming the bottom of the intake manifold riser and an underside forming the top of the chamber. The heater wall may be heated by exhaust gases or bypassed water from the cooling system of the engine. The chamber is shallow so that surface of the heater wall of volume of the chamber will be high enough for rapid evaporation of fuel. The drops of fuel released from the engine carburetor drop down directly onto the heater wall and fuel vapor flows out of the chamber into the intake manifold. The apertured wall is not formed with holes in the peripheral area thereof to prevent the drops of fuel from splashing and/or spilling out of the chamber into the intake manifold.
