Internal combustion engine and starting control device of internal combustion engine

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 in which the reforming air is first supplied to the reforming catalyst, and then the reforming fuel is supplied to the reforming catalyst, and before the reforming air is supplied to the reforming unit, a temperature of the reforming catalyst is raised to a predetermined preheating temperature higher than an adiabatic reaction temperature in partial oxidation reaction of the reforming fuel;
• and
• a starting unit that starts the internal combustion engine after the reforming by the reforming catalyst starts,
• wherein the engine is started after the reforming by the reforming catalyst starts.

A starting control device of an internal combustion engine, which controls 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, and 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, and a reforming catalyst heating unit that raises a temperature of the reforming catalyst, the starting control device comprising:

• a heating control unit that raises the temperature of the reforming catalyst to a predetermined preheating temperature higher than an adiabatic reaction temperature in partial oxidation reaction of the reforming fuel by the reforming catalyst heating unit, before the reforming mixture is supplied to the reforming catalyst;
• a reforming control unit that supplies the reforming mixture to the reforming catalyst after the temperature of the reforming catalyst becomes higher than the preheating temperature;
• and
• a starting control unit that starts the internal combustion engine after the reforming by the reforming catalyst starts.
