| 1. An internal combustion engine, which is an internal combustion engine driven by igniting a mixture of air and fuel with
a spark unit to thereby combust the fuel in a combustion chamber, the internal combustion engine comprising:
a reforming unit that reforms a reforming mixture of reforming fuel and reforming air by a reforming catalyst to generate
reformed gas containing hydrogen and supply this reformed gas to the combustion chamber;
a reforming catalyst heating unit that raises a temperature of the reforming catalyst to a predetermined preheating temperature
higher than an adiabatic reaction temperature in partial oxidation reaction of the reforming fuel, before the reforming mixture
is supplied to the reforming catalyst; and
a starting unit that starts the internal combustion engine,
wherein the engine is started after the reforming by the reforming catalyst starts.
