Abstract
Hydrogen-rich reformate gas is produced by a fuel reformer () from fuel vapor containing hydrocarbon, which is produced by a fuel vaporizer (), by means of a partial oxidation reaction and a steam reforming reaction. A fuel injector () supplies fuel to the fuel vaporizer (), and an air injector () supplies air to the fuel vaporizer (). A glow plug () partially oxidizes the air-fuel mixture inside the fuel vaporizer (). By controlling the air supply amount in relation to the fuel supply amount to obtain an excess air factor corresponding to a predetermined rich air-fuel ratio, a part of the air-fuel mixture in the fuel vaporizer () is partially oxidized, and the remaining fuel vapor is heated by the oxidation heat. As a result, the partial oxidation reaction and steam reforming reaction in the fuel reformer () are performed with a favorable balance.
