Summary:PROBLEM TO BE SOLVED: To provide a technique for highly accurately measuring a cetane number of fuel, while the fuel is actually used for operating an internal combustion engine. SOLUTION: In a fuel cut state of the internal combustion engine (S101), a cetane number measurement fuel is injected (S105) by a specific amount of fuel into a combustion chamber in a compression stroke or an expansion stroke. The cetane number of the fuel is measured based on a period from specific timing to ignition timing wherein the fuel injected by the cetane measurement fuel injection is ignited.
