Abstract: A fuel vaporizing device has a body with a fuel inlet, air inlet, and vapor outlet. A spiral conduit is formed in the body with a length of 2-6 feet. The spiral conduit has a first end coupled to the air inlet and second end coupled to the vapor outlet. An injector assembly is disposed within the body and coupled to the fuel inlet. The injector assembly introduces atomized fuel into the first end of the spiral conduit. The fuel and air mixture is converted to vaporized fuel through a length of the spiral conduit. The vaporized fuel exits at the vapor outlet. The injector assembly has a compression spring disposed in a cavity of an injector body. An injector piston is disposed in the cavity of the injector body contacting the spring. An injector outlet introduces the atomized fuel into the spiral conduit when the injector piston is displaced.
