To provide a photocatalyst fuel reforming system of an internal combustion engine that can reform fuel responsively depending on an operating state and supply fuel with an octane value suitable for the operating state, and that can therefore control ignition time and be suitably used, for example, for an internal combustion engine using HCCI gasoline.
A photocatalyst fuel reforming system 1 of an internal combustion engine includes an internal combustion engine 2, a fuel tank 3 for supplying fuel to the internal combustion engine 2, a light source 6 for emitting light, and a photocatalyst 7 provided to a flow path 4 for the fuel supplied from the fuel tank 3 to the internal combustion engine 2. The photocatalyst fuel reforming system 1 further includes light control means for changing a wavelength range and/or quantity of light emitted from the light source 6, and the light control means changes the wavelength range and/or quantity of the light emitted from the light source 6 based on the operating state of the internal combustion engine 2, so that the photocatalyst 7 absorbs at least a part of the light emitted from the light source to improve the octane value of the fuel.
