Abstract:
1. A fuel supply device for supplying fuel to an internal combustion engine, comprising: a reforming catalyst which induces an isomerization reforming reaction and a decomposition reforming reaction of a source fuel at a different reaction ratio depending on a catalyst temperature of the reforming catalyst; a catalyst temperature varying mechanism which varies the catalyst temperature; a fuel supply mechanism which supplies an isomerized fuel generated by the isomerization reforming reaction and a decomposed fuel generated by the decomposition reforming reaction respectively to the internal combustion engine; and a programmable controller programmed to: determine whether a request for increasing a reaction ratio of the isomerization reforming reaction exists; control the catalyst temperature varying mechanism to regulate the catalyst temperature to a temperature below a predetermined temperature, when the request for increasing the reaction ratio of the isomerization reforming reaction has been determined to exist; determine whether a request for increasing a reaction ratio of the decomposition reforming reaction exists; and control the catalyst temperature varying mechanism to regulate the catalyst temperature to a temperature above the predetermined temperature when the request for increasing the reaction ratio of the decomposition reforming reaction has been determined to exist.
