Fuel property sensing device
A control unit executes sensing of a fuel property of fuel based on a physical value, which is related to a combustion state of the fuel in an internal combustion engine, when it is determined that a predetermined prerequisite operational condition for the sensing of the fuel property is satisfied upon occurrence of at least one of consumption of a predetermined amount of fuel, traveling of a vehicle through a predetermined travel distance, and execution of a predetermined number of operation cycle(s). The predetermined prerequisite operational condition may be satisfied when an operational state of the internal combustion engine is a deceleration fuel cut-off state or an idle state.
