PROBLEM TO BE SOLVED: To provide a fuel reforming device capable of further accurately determining properties of fuel stored in a reforming fuel storing means. SOLUTION: An ECU 60 is provided with a torque difference change rate determining portion determining the properties of reforming fuel stored in a reforming fuel tank 54 from the change rate of difference between estimated torque and actual torque of an engine. Therefore, the properties of the fuel supplied to a reforming catalyst can be determined. When the reforming fuel having properties except required one is supplied into the reforming catalyst 32, the reforming catalyst 32 is deteriorated and the producing amount of reforming gas is reduced, so that there is a risk of reducing the actual torque of the engine 1. Therefore, by checking the change rate of the difference between the estimated torque and the actual torque of the engine 1 when the reforming catalyst 32 ideally functions, the properties of the fuel supplied into the reforming catalyst 32 can be determined. Consequently, the properties of the fuel stored in the reforming fuel tank 54 as the reforming fuel storing means can be further accurately determined. COPYRIGHT: (C)2009,JPO&INPIT
