Abstract
A sub-injector injects liquid fuel into a vaporized-fuel chamber of a vaporized-fuel tank. The injected liquid fuel is vaporized in the vaporized-fuel chamber. The generated vaporized fuel is supplied to a combustion chamber through a vaporized-fuel passage. A supply of the vaporized fuel to the combustion chamber is controlled by a purge valve. Thereby, the vaporized fuel can be precisely supplied to the engine at a start of engine, so that emission can be reduced.
