A fuel property detector for an internal combustion engine determines a cetane number with high accuracy even when a high-cetane fuel is used. The fuel property detector includes a cylinder pressure detection device; ignition delay time calculating device for calculating ignition delay time in accordance with the cylinder pressure; a high-cetane fuel judgment device for judging based on the ignition delay time whether the cetane number of an employed fuel is high; an ignition delay time extension device that increases the ignition delay time by correcting a control parameter for the internal combustion engine; an ignition delay time recalculation device for recalculating the ignition delay time based on cylinder pressure after the ignition delay time is increased by the ignition delay time extension device; and a cetane number calculation device for calculating the cetane number of the employed fuel based on the recalculated ignition delay time.
