Abstract
A liquid fuel vaporizer includes a combustion chamber in which heat is generated by burning fuel therein, an vaporization chamber in which liquid fuel is vaporized by the heat transferred from the combustion chamber to the vaporization chamber. Both chambers are integrally built in a housing, and liquid fuel is supplied from a single injector to both chambers. Liquid fuel consisting of small particles is supplied to the combustion chamber to improve combustion efficiency. Vaporized fuel in the vaporization chamber is prevented from being ignited and burnt therein by various manners, such as intercepting combustion flame, controlling an air/fuel ratio in a range out of a combustible range, or keeping vaporized fuel temperature at a level lower than its self-igniting temperature.
