PROBLEM TO BE SOLVED: To provide a fuel reforming device in which fuel, air and water is supplied to a reformer 6 from fuel valve 11, an air valve 15, and a water valve 19, a reformed gas containing mainly hydrogen and carbon monoxide is generated by partial oxidation reaction and vapor reforming reaction, and the reformed gas is supplied through gas valves 23, 24 from a mixer 4 to a suction passage 2 of an engine 1, wherein after stop of an engine, restart of the engine is prepared by storing the reformed gas more than that at the stop of the engine, and lowering of temperature in the reformer 6 is accelerated after stop of the engine. SOLUTION: When stop of an engine 1 is detected, gas valves 23, 24 and an air valve 15 are closed while a fuel valve 11 and a water valve 19 are kept opened to supply fuel and water to a reformer 6 and to cause vapor reforming reaction i. e., endothermic reaction by remaining heat of the reformer 6. After stop of the engine, the reformed gas produced in the reformer 6 is stored in a reformed gas storage tank 20.
