Non-contacting fuel vaporizer

A non-contact fuel vaporizer (10) adds heat to the injected fuel by combining the fuel with heated air in a vaporization chamber (12) downstream of air supply inlets (30). The fuel is metered axially through a conventional fuel injector (18). The heated air is metered through an air director plate (24) that introduces the air in a helical trajectory concentrically around the injector spray. When the hot swirling air comes in contact with the atomized fuel, substantially all of the fuel is vaporized before coming into contact with a wall (14) of the vaporization chamber (12).
