Abstract: There is disclosed apparatus for converting liquid fuel into a highly combustible dry gaseous fuel for internal combustion engines comprising a fuel injector connected to a heated baffle chamber containing a multiplicity of baffles, heated to the exhaust temperature of an internal combustion engine. The heated baffle chamber in turn communicates with an unheated baffle chamber containing a plurality of unheated baffles, which in turn communicates with a distribution chamber with throttle valves and a venturi to controllably disperse the dry gaseous fuel mixed with air into the intake manifold of an internal combustion engine.
